Do drug-eluting stents improve outcomes after ST-elevation myocardial infarction (STEMI)?

Background: Drug-eluting stents reduce restenosis rates compared to bare-metal stents. However, there is concern drug-eluting stents increase the risk of stent thrombosis leading to MI and death. Prior studies compared patients who received bare-metal versus those who received drug-eluting stents. Outcomes on a population level might provide new insight.

Study design: Observational study.

Setting: 100% national sample of patients 65 and older who received a coronary stent from 2002-05 enrolled in the traditional fee-for-service Medicare program.

Synopsis: 38,917 patients in the pre-drug-eluting-stent era from October 2002 to March 2003 received bare-metal stents. Nearly 62% of 28,086 patients studied from September to December 2003 received drug-eluting stents. The remaining 38.5% received bare-metal stents. Outcomes of percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), STEMI, and death were observed through December 31, 2005.

Patients in the drug-eluting-stent era had a lower two-year risk for repeat revascularization compared to patients in the bare-metal-stent era. In the drug-eluting versus bare-metal eras, repeat PCI was 17.1% versus 20.0% (p<0.001) and need for CABG was 2.7% versus 4.2% (p<0.01). Comparing adjusted outcomes for death, or STEMI, at two years, the two groups appeared similar.

The study did have limitations: the data only reflect sirolimus stents, the authors could not assess dual-antiplatelet therapy or obtain information on coronary anatomy or procedure details to account for selection bias in stent utilization, and the patients were all Medicare beneficiaries.

Bottom line: Drug-eluting stents are associated with fewer repeat revascularization procedures than bare-metal stents, but have not shown a significant improvement in the subsequent risk of STEMI or death.

Does case volume affect hospital performance for publicly reported process measures?

Background: Hospitals are increasingly graded and compared to one another. “Top medical centers” are defined as those within the top 10% of hospitals in specified performance measures. Hospitals with large and small case volumes might not be compared evenly and fairly.

Study design: Eight publicly reported process measures for acute myocardial infarction (AMI) were compared to hospital case volume, process performance, and label as “top hospital.”

Setting: Data were analyzed from the Hospital Quality Alliance for 3,761 hospitals from January to December 2005.

Synopsis: Hospitals with large case volume overall had better process performance. For example, looking at use of beta-blockers in patients with AMI on arrival to a hospital, small-volume hospitals (<10 AMI cases) averaged 72% while large volume (>100 AMI cases) averaged 80% (p<0.001). However, hospitals with small case volumes were more likely to receive “top hospital” rating even when hospitals with very low case volumes were excluded.

Hospital quality reporting that does not account for case volume is misleading to hospitals and consumers. In this study, larger-volume hospitals appeared to perform better in process measures, but were less likely to receive “top hospital” rating.

Bottom line: Hospitals with large and small case volumes can easily be compared to one another for process measures in AMI.

What is the predictive value of QRS duration in patients hospitalized with worsening CHF?

Background: In outpatients, a prolonged QRS duration (greater than 120 ms) is associated with increased mortality. Its value in the inpatient setting is unclear. For patients hospitalized with CHF exacerbations, establishing the value of QRS duration may allow for tailored management.

Study design: Retrospective post hoc analysis from the Efficacy of Vasopressin Antagonism in Heart Failure Outcome Study with Tolvaptan (EVEREST).

Setting: 4,133 patients were enrolled from North American, South American, and European sites.

Synopsis: Of 2,962 patients included in the final post hoc analysis, 1,321 (44.6%) had a prolonged QRS duration. During a median follow up of 9.9 months, the all-cause mortality rate was 18.7% for patients with a normal baseline QRS duration and 28.1% for patients with a prolonged baseline QRS.

After adjusting for confounding variables, patients with a prolonged baseline QRS had a 24% increased risk of all-cause mortality and a 28% increased risk for a composite endpoint of cardiac mortality or hospitalization for heart failure exacerbation.

The retrospective nature of the analysis represents the major limitation of this study. In addition, most of the enrolled patients were white, which limits the studies generalizability to other ethnic groups.

Bottom Line: A prolonged QRS duration for patients admitted with decompensated left ventricular heart failure is common and may be associated with increased morbidity and mortality.

For patients with out-of-hospital cardiac arrest, does the addition of vasopressin to epinephrine in a protocol for ACLS improve outcomes?

Background: The outcome for patients experiencing cardiac arrest who require vasopressors remains extremely poor. Despite disappointing data on vasopressin as an alternative treatment during cardiac arrest, a recent subgroup analysis suggested patients who received epinephrine and vasopressin together had superior clinical outcomes.

Study Design: Prospective multicenter randomized double-blind controlled trial.

Setting: 31 emergency medical service organizations in France.

Synopsis: Of the 2,894 patients, 20.7% of those receiving combination treatment (vasopressin plus epinephrine) survived to hospital admission versus 21.3% of those in the epinephrine-only group. For those same groups, 1.7% of combination and 2.3% of epinephrine-only patients survived to hospital discharge. No significant outcome differences were found in any group or subgroup analysis.

The study had lower-than-expected overall survival to hospital discharge, which may have handicapped its effort to find a true difference in treatment arms.

Bottom line: The addition of vasopressin to epinephrine in the treatment of out-of-hospital cardiac arrest does not improve outcomes.

Is oral rivaroxaban more efficacious than subcutaneous enoxaparin in preventing VTE after hip-replacement surgery?

Background: Venous thromboembolism (VTE) prophylaxis after total hip replacement (THR) is important but can be cumbersome because the most commonly used anticoagulants are either subcutaneous or require frequent monitoring. Rivaroxaban, an oral direct inhibitor of factor Xa may provide more convenient anticoagulation postoperatively. However, its efficacy and safety are unknown.

Study design: Randomized double-blind trial.

Setting: Multicenter study performed in 27 countries.

Synopsis: Patients undergoing THR surgery were randomized to oral rivaroxaban (10mg once daily without monitoring, started six to eight hours after surgery) or subcutaneous enoxaparin (40mg once daily, started 12 hours prior to surgery). After surgery, prophylaxis was administered for 35 days. The primary outcome was a composite of asymptomatic deep venous thrombosis (DVT), symptomatic DVT or pulmonary embolism (PE), or death from any cause at 36 days after surgery.

In the enoxaparin group, 3.7% of patients experienced the primary outcome. This decreased to 1.1% in the rivaroxaban group. Approximately one-third of events were symptomatic. Major bleeding occurred in 0.1% and 0.3% (p=NS) of patients in the enoxaparin and rivaroxaban groups, respectively.

The study is limited by the exclusion of 1,388 of the 4,541 patients (30.6%) randomized, primarily due to having inadequate venography. Also, because the majority of thromboembolic events were asymptomatic, the primary outcome overemphasizes the clinical difference.

Bottom line: Oral rivaroxaban without monitoring is more efficacious than, and as safe as, subcutaneous enoxaparin when used for VTE prophylaxis for THR.

Is LMWH more efficacious than UFH in preventing postoperative VTE in cancer patients?

Background: Patients with cancer are at increased risk for VTE and require prophylaxis to prevent this complication postoperatively. Low molecular weight heparin (LMWH) has proven more efficacious than subcutaneous unfractionated heparin (UFH) in other settings (e.g., DVT treatment). However, it is still unknown whether LMWH offers better prophylaxis compared to UFH for cancer patients undergoing surgery.

Study design: Systematic review and meta-analysis.

Setting: 14 randomized controlled trials.

Synopsis: Eleven trials exclusively examined patients with cancer (n=4006) and three trials reported data for cancer patients as subgroups (n=1816). There were in differences in mortality, pulmonary embolism, and symptomatic DVT rates between the two groups.

LMWH was associated with a decrease in total (asymptomatic or symptomatic) DVT (RR, 0.72; 95% CI, 0.55-0.94). Rates of major bleeding, minor bleeding, and intraoperative blood loss were similar between the two treatments.

This meta-analysis is limited because 12 remaining trials (n=3185) also enrolled cancer patients but did not provide specific data for the cancer patient subgroup. The study also is limited by the heterogeneity of the original trials, including utilizing varying LMWHs and dosing regimens, numerous types of surgeries, and a wide range of neoplasms.

Bottom line: LMWH does not decrease mortality, pulmonary embolism, or symptomatic DVT compared to UFH in cancer patients undergoing surgery.

Does salmeterol added to inhaled corticosteroids improve severe asthma-related events?

Background: Asthma is a chronic disease causing major morbidity and mortality worldwide. Disease guidelines recommend all patients with persistent asthma be treated with inhaled corticosteroids. These same guidelines recommend adding a long-acting beta-agonist for patients whose symptoms persist. However, the safety of this practice has come under scrutiny.

Study design: Meta-analysis.

Setting: Sixty-six randomized, controlled trials conducted worldwide.

Synopsis: Analysis included 66 GlaxoSmithKline trials with a total of 20,966 patients with persistent asthma. Patients used either salmeterol (50mcg twice daily) plus inhaled corticosteroid (10,400 patients) or inhaled corticosteroid alone (10,566 patients).

Results showed no differences in asthma-related hospitalizations, asthma-related intubations, or deaths between the two groups. However, due to the low number of events, definitive conclusions are difficult to make. Severe asthma exacerbations requiring systemic corticosteroids significantly decreased in the inhaled corticosteroid plus salmeterol group.

The study is limited by it inclusion of only those trials sponsored by GlaxoSmithKline and by the short duration of most of the studies. Additionally, the studies included in the analysis used clinical outcomes as secondary endpoints.

Bottom line: Adding salmeterol to inhaled corticosteroid decreases severe asthma exacerbations and is likely safe, but does not have an effect on asthma-related hospitalization or death.

Is an early invasive strategy effective in women with unstable angina or NSTEMI?

Background: Despite many trials showing the value of an early invasive strategy for patients with non-ST-segment elevation acute coronary syndrome (NSTE ACS), data from several trials question this benefit in women. Some trials show higher risk of death and myocardial infarction (MI) in subgroup analysis of women.

Study Design: Meta-analysis.

Setting: Eight randomized, controlled trials conducted worldwide.

Synopsis: Analysis included eight trials with 10,412 patients (3,075 women) with NSTE ACS. The invasive group (5,083 patients) was defined as those referred for coronary angiography with subsequent intervention as needed. The composite endpoint of death, MI, or rehospitalization within 12 months with ACS occurred in 21.1% of the invasive group and 25.9% of the medically managed group (OR, 0.78; CI, 0.61-0.98).

The subgroup, including only women, had a non-statistically significant OR of 0.81 (CI, 0.65-1.01), including no effect on all-cause mortality, nonfatal MI, or the composite of death and MI. However, women with high-risk features (elevated biomarkers) undergoing the invasive strategy had a significant reduction in the composite endpoint (OR, 0.67; CI, 0.50-0.88).

The study is limited by the use of subgroup analysis, secondary endpoints, heterogeneity between trials, and possible publication bias.

Bottom line: Early invasive strategy is effective in men and high-risk women with NSTE ACS, but not in low-risk women.

What strategies are used to prevent contrast-induced acute kidney injury?

Background: Contrast-induced acute kidney injury (CIAKI) is a condition potentially amenable to preventive care. Several trials have identified intravenous hydration, N-acetylcysteine, and withdrawal of NSAIDS as interventions that reduce the possibility of CIAKI in high-risk patients. Little is known about whether healthcare providers routinely use these strategies.

Study design: Prospective observational cohort study.

Setting: Veterans Affairs (VA) Pittsburgh Healthcare System.

Synopsis: 11,410 patients scheduled for radiographic procedures were screened. After exclusion criteria and eligibility, 660 patients with an estimated glomerular filtration rate less than 60ml/min/1.73m2 were identified. Usage of intravenous fluids, N-acetylcysteine, and discontinuation of NSAIDS were recorded. Serum creatinine (SCr) was measured 48 to 96 hours post-procedure. CIAKI was defined as relative increase in SCr from baseline (≥25%, ≥50% and ≥100%) and absolute increase in SCr levels from baseline (≥0.25, ≥0.5, and ≥1.0). CIAKI association with adverse outcomes was evaluated by tracking 30-day mortality, need for dialysis, and hospitalization.

The incidence of CIAKI was less common in patients undergoing CT scans versus those having angiograms. Adverse 30-day outcomes were uncommon. Pre- and post-procedure intravenous hydration was administered to 40% of study patients, more commonly with coronary angiogram than with computed tomography (91.2% vs. 16%, p<0.0001). N-acetylcysteine was administered to 39.2%. Only 6.8% of those taking NSAIDS reported being told to discontinue the medication.

Study limitations include the small sample size and the single site location, both limiting generalizability.

Bottom line: Clinically significant CIAKI is uncommon, and preventive care is not uniformly implemented in patients undergoing contrast-enhanced radiographic procedures.

How does hyperglycemia affect morbidity and mortality in children admitted to a community pediatric hospital?

Background: Inpatient hyperglycemia in adult patients is a predictor of poor clinical outcomes. The association of hyperglycemia and clinical outcomes in children admitted to a general community hospital has not been studied.

Study design: Retrospective observational cohort study.

Setting: A community pediatric hospital in Atlanta, Ga.

Synopsis: Review of medical records of 903 consecutive pediatric patients admitted to critical and non-critical areas took place. Of these, 542 patients constituted the study population. The study excluded 342 patients who didn’t have a blood glucose measurement. Hyperglycemia was defined as an admission or in-hospital blood glucose greater than 120mg/dl.

One-fourth of the children admitted to the hospital had hyperglycemia, most without a prior history of diabetes. The presence of hyperglycemia on admission was not associated with increased length of stay (LOS) or increased mortality. Children with hyperglycemia were more likely to be admitted to the ICU and had longer ICU LOS.

This was a retrospective study conducted at a single site whose demographics and disease spectrum may differ from those of other institutions. There were an insufficient number of deaths to make any conclusions regarding the impact of hyperglycemia on mortality. Prospective, randomized, multicenter trials are needed to better elucidate the effects of in-patient hyperglycemia.

Bottom line: Hyperglycemia is common in children with or without diabetes admitted to the hospital, and is associated with increased ICU admissions and ICU length of stay. Its connection to mortality is inconclusive.

Is an early invasive strategy effective in women with unstable angina or NSTEMI?

Background: Despite many trials showing the value of an early invasive strategy for patients with non-ST-segment elevation acute coronary syndrome (NSTE ACS), data from several trials question this benefit in women. Some trials show higher risk of death and myocardial infarction (MI) in subgroup analysis of women.

Study Design: Meta-analysis.

Setting: Eight randomized, controlled trials conducted worldwide.

Synopsis: Analysis included eight trials with 10,412 patients (3,075 women) with NSTE ACS. The invasive group (5,083 patients) was defined as those referred for coronary angiography with subsequent intervention as needed.

The subgroup, including only women, had a non-statistically significant OR of 0.81 (CI, 0.65-1.01), including no effect on all-cause mortality, nonfatal MI, or the composite of death and MI. However, women with high-risk features (elevated biomarkers) undergoing the invasive strategy had a significant reduction in the composite endpoint (OR, 0.67; CI, 0.50-0.88).

Bottom line: Early invasive strategy is effective in men and high-risk women with NSTE ACS, but not in low-risk women.

What strategies are used to prevent contrast-induced acute kidney injury?

Background: Contrast-induced acute kidney injury (CIAKI) is a condition potentially amenable to preventive care. Several trials have identified intravenous hydration, N-acetylcysteine, and withdrawal of NSAIDS as interventions that reduce the possibility of CIAKI in high-risk patients. Little is known about whether healthcare providers routinely use these strategies.

Study design: Prospective observational cohort study.

Setting: Veterans Affairs (VA) Pittsburgh Healthcare System.

Synopsis: 11,410 patients scheduled for radiographic procedures were screened. After exclusion criteria and eligibility, 660 patients with an estimated glomerular filtration rate less than 60ml/min/1.73m2 were identified. Usage of intravenous fluids, N-acetylcysteine, and discontinuation of NSAIDS were recorded. Serum creatinine (SCr) was measured 48 to 96 hours post-procedure. CIAKI was defined as relative increase in SCr from baseline (≥25%, ≥50% and ≥100%) and absolute increase in SCr levels from baseline (≥0.25, ≥0.5, and ≥1.0). CIAKI association with adverse outcomes was evaluated by tracking 30-day mortality, need for dialysis, and hospitalization.

The incidence of CIAKI was less common in patients undergoing CT scans versus those having angiograms. Adverse 30-day outcomes were uncommon. Pre- and post-procedure intravenous hydration was administered to 40% of study patients, more commonly with coronary angiogram than with computed tomography (91.2% vs. 16%, p<0.0001). N-acetylcysteine was administered to 39.2%. Only 6.8% of those taking NSAIDS reported being told to discontinue the medication.

Study limitations include the small sample size and the single site location, both limiting generalizability.

Bottom line: Clinically significant CIAKI is uncommon, and preventive care is not uniformly implemented in patients undergoing contrast-enhanced radiographic procedures.

How does hyperglycemia affect morbidity and mortality in children admitted to a community pediatric hospital?

Background: Inpatient hyperglycemia in adult patients is a predictor of poor clinical outcomes. The association of hyperglycemia and clinical outcomes in children admitted to a general community hospital has not been studied.

Study design: Retrospective observational cohort study.

Setting: A community pediatric hospital in Atlanta, Ga.

Synopsis: Review of medical records of 903 consecutive pediatric patients admitted to critical and non-critical areas took place. Of these, 542 patients constituted the study population. The study excluded 342 patients who didn’t have a blood glucose measurement. Hyperglycemia was defined as an admission or in-hospital blood glucose greater than 120mg/dl.

One-fourth of the children admitted to the hospital had hyperglycemia, most without a prior history of diabetes. The presence of hyperglycemia on admission was not associated with increased length of stay (LOS) or increased mortality. Children with hyperglycemia were more likely to be admitted to the ICU and had longer ICU LOS.

This was a retrospective study conducted at a single site whose demographics and disease spectrum may differ from those of other institutions. There were an insufficient number of deaths to make any conclusions regarding the impact of hyperglycemia on mortality. Prospective, randomized, multicenter trials are needed to better elucidate the effects of in-patient hyperglycemia.

Bottom line: Hyperglycemia is common in children with or without diabetes admitted to the hospital, and is associated with increased ICU admissions and ICU length of stay. Its connection to mortality is inconclusive.

Do drug-eluting stents improve outcomes after ST-elevation myocardial infarction (STEMI)?

Background: Drug-eluting stents reduce restenosis rates compared to bare-metal stents. However, there is concern drug-eluting stents increase the risk of stent thrombosis leading to MI and death. Prior studies compared patients who received bare-metal versus those who received drug-eluting stents. Outcomes on a population level might provide new insight.

Study design: Observational study.

Setting: 100% national sample of patients 65 and older who received a coronary stent from 2002-05 enrolled in the traditional fee-for-service Medicare program.

Synopsis: 38,917 patients in the pre-drug-eluting-stent era from October 2002 to March 2003 received bare-metal stents. Nearly 62% of 28,086 patients studied from September to December 2003 received drug-eluting stents. The remaining 38.5% received bare-metal stents. Outcomes of percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), STEMI, and death were observed through December 31, 2005.

Patients in the drug-eluting-stent era had a lower two-year risk for repeat revascularization compared to patients in the bare-metal-stent era. In the drug-eluting versus bare-metal eras, repeat PCI was 17.1% versus 20.0% (p<0.001) and need for CABG was 2.7% versus 4.2% (p<0.01). Comparing adjusted outcomes for death, or STEMI, at two years, the two groups appeared similar.

The study did have limitations: the data only reflect sirolimus stents, the authors could not assess dual-antiplatelet therapy or obtain information on coronary anatomy or procedure details to account for selection bias in stent utilization, and the patients were all Medicare beneficiaries.

Bottom line: Drug-eluting stents are associated with fewer repeat revascularization procedures than bare-metal stents, but have not shown a significant improvement in the subsequent risk of STEMI or death.

Does case volume affect hospital performance for publicly reported process measures?

Background: Hospitals are increasingly graded and compared to one another. “Top medical centers” are defined as those within the top 10% of hospitals in specified performance measures. Hospitals with large and small case volumes might not be compared evenly and fairly.

Study design: Eight publicly reported process measures for acute myocardial infarction (AMI) were compared to hospital case volume, process performance, and label as “top hospital.”

Setting: Data were analyzed from the Hospital Quality Alliance for 3,761 hospitals from January to December 2005.

Synopsis: Hospitals with large case volume overall had better process performance. For example, looking at use of beta-blockers in patients with AMI on arrival to a hospital, small-volume hospitals (<10 AMI cases) averaged 72% while large volume (>100 AMI cases) averaged 80% (p<0.001). However, hospitals with small case volumes were more likely to receive “top hospital” rating even when hospitals with very low case volumes were excluded.

Hospital quality reporting that does not account for case volume is misleading to hospitals and consumers. In this study, larger-volume hospitals appeared to perform better in process measures, but were less likely to receive “top hospital” rating.

Bottom line: Hospitals with large and small case volumes can easily be compared to one another for process measures in AMI.

What is the predictive value of QRS duration in patients hospitalized with worsening CHF?

Background: In outpatients, a prolonged QRS duration (greater than 120 ms) is associated with increased mortality. Its value in the inpatient setting is unclear. For patients hospitalized with CHF exacerbations, establishing the value of QRS duration may allow for tailored management.

Study design: Retrospective post hoc analysis from the Efficacy of Vasopressin Antagonism in Heart Failure Outcome Study with Tolvaptan (EVEREST).

Setting: 4,133 patients were enrolled from North American, South American, and European sites.

Synopsis: Of 2,962 patients included in the final post hoc analysis, 1,321 (44.6%) had a prolonged QRS duration. During a median follow up of 9.9 months, the all-cause mortality rate was 18.7% for patients with a normal baseline QRS duration and 28.1% for patients with a prolonged baseline QRS.

After adjusting for confounding variables, patients with a prolonged baseline QRS had a 24% increased risk of all-cause mortality and a 28% increased risk for a composite endpoint of cardiac mortality or hospitalization for heart failure exacerbation.

The retrospective nature of the analysis represents the major limitation of this study. In addition, most of the enrolled patients were white, which limits the studies generalizability to other ethnic groups.

Bottom Line: A prolonged QRS duration for patients admitted with decompensated left ventricular heart failure is common and may be associated with increased morbidity and mortality.

Citation: Wang NC, Maggioni AP, Konstam MA, Zannad F, Drasa HB, Burnett JC, et al. Clinical implications of QRS duration in patients hospitalized with worsening heart failure and reduced left ventricular ejection fraction. JAMA. 2008;299(22):2656-2666.

For patients with out-of-hospital cardiac arrest, does the addition of vasopressin to epinephrine in a protocol for ACLS improve outcomes?

Background: The outcome for patients experiencing cardiac arrest who require vasopressors remains extremely poor. Despite disappointing data on vasopressin as an alternative treatment during cardiac arrest, a recent subgroup analysis suggested patients who received epinephrine and vasopressin together had superior clinical outcomes.

Study Design: Prospective multicenter randomized double-blind controlled trial.

Setting: 31 emergency medical service organizations in France.

Synopsis: Of the 2,894 patients, 20.7% of those receiving combination treatment (vasopressin plus epinephrine) survived to hospital admission versus 21.3% of those in the epinephrine-only group. For those same groups, 1.7% of combination and 2.3% of epinephrine-only patients survived to hospital discharge. No significant outcome differences were found in any group or subgroup analysis.

The study had lower-than-expected overall survival to hospital discharge, which may have handicapped its effort to find a true difference in treatment arms.

Bottom line: The addition of vasopressin to epinephrine in the treatment of out-of-hospital cardiac arrest does not improve outcomes.

Is oral rivaroxaban more efficacious than subcutaneous enoxaparin in preventing VTE after hip-replacement surgery?

Background: Venous thromboembolism (VTE) prophylaxis after total hip replacement (THR) is important but can be cumbersome because the most commonly used anticoagulants are either subcutaneous or require frequent monitoring. Rivaroxaban, an oral direct inhibitor of factor Xa may provide more convenient anticoagulation postoperatively. However, its efficacy and safety are unknown.

Study design: Randomized double-blind trial.

Setting: Multicenter study performed in 27 countries.

Synopsis: Patients undergoing THR surgery were randomized to oral rivaroxaban (10mg once daily without monitoring, started six to eight hours after surgery) or subcutaneous enoxaparin (40mg once daily, started 12 hours prior to surgery). After surgery, prophylaxis was administered for 35 days. The primary outcome was a composite of asymptomatic deep venous thrombosis (DVT), symptomatic DVT or pulmonary embolism (PE), or death from any cause at 36 days after surgery.

In the enoxaparin group, 3.7% of patients experienced the primary outcome. This decreased to 1.1% in the rivaroxaban group. Approximately one-third of events were symptomatic. Major bleeding occurred in 0.1% and 0.3% (p=NS) of patients in the enoxaparin and rivaroxaban groups, respectively.

The study is limited by the exclusion of 1,388 of the 4,541 patients (30.6%) randomized, primarily due to having inadequate venography. Also, because the majority of thromboembolic events were asymptomatic, the primary outcome overemphasizes the clinical difference.

Bottom line: Oral rivaroxaban without monitoring is more efficacious than, and as safe as, subcutaneous enoxaparin when used for VTE prophylaxis for THR.

Is LMWH more efficacious than UFH in preventing postoperative VTE in cancer patients?

Background: Patients with cancer are at increased risk for VTE and require prophylaxis to prevent this complication postoperatively. Low molecular weight heparin (LMWH) has proven more efficacious than subcutaneous unfractionated heparin (UFH) in other settings (e.g., DVT treatment). However, it is still unknown whether LMWH offers better prophylaxis compared to UFH for cancer patients undergoing surgery.

Study design: Systematic review and meta-analysis.

Setting: 14 randomized controlled trials.

Synopsis: Eleven trials exclusively examined patients with cancer (n=4006) and three trials reported data for cancer patients as subgroups (n=1816). There were in differences in mortality, pulmonary embolism, and symptomatic DVT rates between the two groups.

LMWH was associated with a decrease in total (asymptomatic or symptomatic) DVT (RR, 0.72; 95% CI, 0.55-0.94). Rates of major bleeding, minor bleeding, and intraoperative blood loss were similar between the two treatments.

This meta-analysis is limited because 12 remaining trials (n=3185) also enrolled cancer patients but did not provide specific data for the cancer patient subgroup. The study also is limited by the heterogeneity of the original trials, including utilizing varying LMWHs and dosing regimens, numerous types of surgeries, and a wide range of neoplasms.

Bottom line: LMWH does not decrease mortality, pulmonary embolism, or symptomatic DVT compared to UFH in cancer patients undergoing surgery.

Does salmeterol added to inhaled corticosteroids improve severe asthma-related events?

Background: Asthma is a chronic disease causing major morbidity and mortality worldwide. Disease guidelines recommend all patients with persistent asthma be treated with inhaled corticosteroids. These same guidelines recommend adding a long-acting beta-agonist for patients whose symptoms persist. However, the safety of this practice has come under scrutiny.

Study design: Meta-analysis.

Setting: Sixty-six randomized, controlled trials conducted worldwide.

Synopsis: Analysis included 66 GlaxoSmithKline trials with a total of 20,966 patients with persistent asthma. Patients used either salmeterol (50mcg twice daily) plus inhaled corticosteroid (10,400 patients) or inhaled corticosteroid alone (10,566 patients).

Results showed no differences in asthma-related hospitalizations, asthma-related intubations, or deaths between the two groups. However, due to the low number of events, definitive conclusions are difficult to make. Severe asthma exacerbations requiring systemic corticosteroids significantly decreased in the inhaled corticosteroid plus salmeterol group.

The study is limited by it inclusion of only those trials sponsored by GlaxoSmithKline and by the short duration of most of the studies. Additionally, the studies included in the analysis used clinical outcomes as secondary endpoints.

Bottom line: Adding salmeterol to inhaled corticosteroid decreases severe asthma exacerbations and is likely safe, but does not have an effect on asthma-related hospitalization or death.

Is an early invasive strategy effective in women with unstable angina or NSTEMI?

Background: Despite many trials showing the value of an early invasive strategy for patients with non-ST-segment elevation acute coronary syndrome (NSTE ACS), data from several trials question this benefit in women. Some trials show higher risk of death and myocardial infarction (MI) in subgroup analysis of women.

Study Design: Meta-analysis.

Setting: Eight randomized, controlled trials conducted worldwide.

Synopsis: Analysis included eight trials with 10,412 patients (3,075 women) with NSTE ACS. The invasive group (5,083 patients) was defined as those referred for coronary angiography with subsequent intervention as needed. The composite endpoint of death, MI, or rehospitalization within 12 months with ACS occurred in 21.1% of the invasive group and 25.9% of the medically managed group (OR, 0.78; CI, 0.61-0.98).

The subgroup, including only women, had a non-statistically significant OR of 0.81 (CI, 0.65-1.01), including no effect on all-cause mortality, nonfatal MI, or the composite of death and MI. However, women with high-risk features (elevated biomarkers) undergoing the invasive strategy had a significant reduction in the composite endpoint (OR, 0.67; CI, 0.50-0.88).

The study is limited by the use of subgroup analysis, secondary endpoints, heterogeneity between trials, and possible publication bias.

Bottom line: Early invasive strategy is effective in men and high-risk women with NSTE ACS, but not in low-risk women.

Ed note: This article is the second in a series of interviews with members of Team Hospitalist: 12 hospital medicine experts who are serving a two-year term as special editorial consultants to our magazine.

Ever consider working as an academic hospitalist? Here to give you the scoop on what it’s like is “Team Hospitalist” member R. Neal Axon, MD, assistant professor of internal medicine and pediatrics at the Medical University of South Carolina (MUSC) in Charleston.

Dr. Axon completed his residency at Duke University Medical Center and received his medical degree from the University of Alabama School of Medicine in 2000.

Why is it important to conduct research in hospital medicine?

We haven’t perfected medicine just yet, and until we do we have to work to make it better. Even though hospital medicine research is different from clinical medicine, we need to have people who are working to make the systems of care better.

What attracted you to academic medicine?

I love teaching residents and medical students, and I missed doing it when I entered in private practice. I just completed my master’s at MUSC in clinical research. My department was very supportive and even paid my tuition.

Is it difficult to balance research work with shift work?

It’s definitely a challenge. Fortunately for me, my group does not have shift work in the traditional sense. We do have a night shift, but it’s something we do on an infrequent basis. It would be extremely difficult to do in a seven-on, seven-off schedule that most hospitalists have.

What type of research are you working on?

I’m currently doing some work with hypertension. One of the projects is doing survey work where we access the attitudes of providers (doctors and house staff) on what to do with patients who have hypertension. My observation has been that, in many cases, when patients are admitted to a hospital, they also have high blood pressure that may equate with hypertension in the outpatient setting. It’s not clear when that should be addressed--or how. This survey would help us understand that.

What do you like about what you do?

I worry more about what the department chief thinks than what the CEO of the hospital thinks. At community and non-teaching hospitals, the focus is much more on the bottom line.

So is it impossible to do research if you work at a non-teaching hospital?

I think it’s likely to be more difficult--in that setting--to be a pure clinical researcher, but I do think there are opportunities out there for every day hospitalists to participate in research. This is one of the things I’m currently working on as a member of the SHM Research Committee. One deliverable we’re excited about is the fact that there will be sessions at the [2009] annual meeting in Chicago that will specifically address how hospitalists can do research.

Another thing I hope can evolve is practice-based research networks, which exist in the primary care setting, but not so much in hospital medicine. These networks include groups of community doctors who band together to do clinical research projects. Central leadership helps the members of the group come up with research questions. This is something I’m working on in my state to develop, but this type of setup does exist in other areas.

What advice do you have for hospitalists who are interested in research?

The most important piece of advice is to find a good mentor.

The second thing is that most medical schools have master’s degree programs that teach you the skills that will get you started in clinical research. I went to medical school, but didn’t learn anything about biostatistics or trial design. TH

Not content with the status quo, SHM has taken significant steps to ensure the society’s reach grows in line with the exponential expansion of hospital medicine. These investments put SHM’s premier educational content into the hands of more hospitalists and increase the society’s ability to hear firsthand—and more quickly react to—the challenges of the field.

One key initiative is SHM’s Champions Program, which identifies hospitalists on the ground to serve as information conduits. These “champions” share feedback with SHM’s staff and leadership about the state of hospital medicine locally, and react to SHM plans and proposals. They also help SHM disseminate news and resources to hospitalists in their communities.

In the Champions Program’s short tenure, it already has proven its value. Champions in 26 key markets are engaged and providing valuable feedback in a wide variety of areas, through participation on conference calls, individual surveys, and even a private breakfast with SHM CEO Larry Wellikson.

On top of that, the program has enabled SHM to expand its pool of identified hospitalists by nearly 60%. This expansion not only means SHM’s education and quality improvement resources will reach more communities, but that the society will gain clout and credibility in all facets of healthcare from divergent groups, such as MedPAC and Congress.

Champions are leaders in their communities, dedicated to making a difference in hospital medicine. If this describes you, consider becoming a Champion. Committing to this vital program means helping to steer the course of hospital medicine locally and globally. If you aspire to become a leader within the society, the Champions Program is a great way to begin.

If you’re interested in becoming a Champion or want to suggest someone in your community who would be a good fit, call Cathy Peduzzi, SHM’s manager of membership outreach programs at (215) 351-2584 or e-mail her at cpeduzzi@hospitalmedicine.org.

Ed note: This article is the first in a series of interviews with members of Team Hospitalist: 12 hospital medicine experts who are serving a two-year term as special editorial consultants to our magazine.

Raajev Alexander, MD, is one busy hospitalist. For the past three years, he has been the lead hospitalist for the Oregon Medical Group, a group that caters to McKenzie-Willamette Medical Center in Springfield, Ore., and Sacred Heart Medical Center in Eugene, Ore. In addition to seeing about 15 patients a day, Dr. Alexander’s expertise in systems development has made him an attractive local expert. He serves on about five hospital committees (“I’ve lost track.”) and often attends meetings on his days off.

Dr. Alexander graduated from the University of Utah School of Medicine in 1995. After completing an internship and residency at Legacy Portland Hospital’s Internal Medicine program in 1998, he was recruited into the Oregon Medical Group.

He recently spoke with The Hospitalist about what he likes about his job, but why he also feels hospitalists should be compensated for the extra duties they undertake.

What attracted you to hospital medicine?

There is this kind of patient acuity where the sort of problems you’re solving seem important. Patients can have serious illnesses so you’re using your skills as an internist. I also like that there is a discreet arch to the hospitalization: There is the beginning of the hospitalization, the middle, the end, and then you’re sort of done. And I like that there is an interdisciplinary aspect; you work with nurses, care management, speech therapists, physical therapists, and ancillary therapists.

What are the challenges of leading a hospitalist group?

I do more than the full number of shifts per year. In addition to that, I go to meetings and deal with everything from a nurse calls and complaints about a hospitalist, to administration of the group. The CEO [of Oregon Medical Group] and I talk about staffing plans and how we can better serve the two hospitals in our area. I also sit on several hospital committees where I contribute my opinions on how to deploy pharmacists to how to redesign the case management program. My group finally decided to compensate me for certain meetings, but I still don’t get paid for half the meetings I go to.

Is this an issue other groups have?

I’m almost positive this is an ongoing issue for all hospitalist groups—at least I think it ought to be.

Hospitalists provide quality improvement on two different levels. One level is that, because we are in the hospital every day, we get to know the nurses, case managers, unit managers, lead respiratory therapists, and physical therapists. So, we effect change just by standing in the hallway.

The cross-education of pharmacists, nurses, and doctors is getting better every day. This is different from the way it used to be when a doctor had to run to the hospital at noon to see two patients, then run back to the office. Another way we improve quality is through committees. For all of the committees I sit on, the hospital gets get all my knowledge and ideas about systems, medications, and cross-reactions of drugs for free. But there isn’t enough time in my day to see patients, do nurse education and respiratory therapy education, to create protocols, and to sit on committees.

What’s the solution?

There are certain business models in hospital medicine that don’t make it possible to last as a hospitalist for 25 to 30 years. For example, there are some models where you get a bonus if you hit 18 to 20 patient encounters a day—even though those numbers are outside the SHM guidelines. If you’re seeing that many patients, you’re not providing optimal patient care.

A good business model is one where you can have 12 encounters per day and make a good living. Or see eight encounters per day and do administrative work, and still make a good living. The way to get there is for the specialty to better identify its mission and who its constituents are. TH

Case

A 66-year-old female with a pack-a-day smoking habit is admitted to orthopedics with a hip fracture following a fall in her home. You are consulted to perform a pre-operative risk assessment and manage her heart failure. The following day, she undergoes an open reduction and internal fixation and does well following the surgery. She is scheduled to be discharged for rehabilitation in two days. She will continue taking her cardiac medications and the narcotics (as needed) for pain. What else can you recommend to reduce her chances of suffering another hip fracture?

Overview

Approximately 300,000 hip fractures occur each year in the United States.¹ The lifetime risk of sustaining a hip fracture is 18% for a woman and 6% for a man.2 One-year mortality after a hip fracture is 20% to 25%, and up to half of patients who live independently prior to their fracture cannot gain independence afterward.

In the late 1990s, inpatient care, nursing home care, and outpatient services associated with hip fractures totaled approximately $14 billion annually. These costs are predicted to reach $50 billion by the year 2040.3 Not surprisingly, second hip fractures are common, with up to 12% of patients suffering another fracture within one year of follow up.1 Risk of morbidity and mortality are even higher after a second hip fracture.

In most experts’ opinions, a fragility fracture indicates osteoporosis and warrants treatment—regardless of bone densitometry findings. Still, multiple studies have shown patients who sustain a hip fracture frequently are not diagnosed, evaluated, or treated for osteoporosis.4 This is analogous to treating an acute coronary syndrome without initiating treatment for a patient’s hypertension and hyperlipidemia prior to discharge. As such, providers clearly are missing an opportunity to begin effective measures at a critical stage in the disease.

Data Review

Physiology of bone strength: Bone minerals—in particular calcium hydroxyapatite—contribute to bone strength by making bone a hard tissue. Collagen adds flexibility and gives bone the ability to absorb energy. The degree of bone mineralization and the number of collagen crosslinks help determine how much stress a bone can tolerate before it breaks. Further, in response to daily stressors, bone accumulates microcracks. Remodeling is then accomplished by bone resorption and formation.5

Estrogen plays an important role in normal remodeling by controlling osteoclast action. Thus, estrogen deficiency leads to prolonged osteoclast activity and increased rates of bone resorption. This explains why bone remodeling typically favors bone resorption later in life and why women are at greatest risk for fracture.5

Vitamin D and calcium: Vitamin D, produced by the skin or ingested, is transported in the circulation by a binding protein to the liver, where it is converted to 25-hydroxyvitamin D. This form is inactive and must be converted by the kidneys to the active form, 1,25-dihydroxyvitamin D. The active form is needed for absorption of renal and intestinal calcium.6

Without vitamin D only 10% to 15% of dietary calcium is absorbed. In one study, serum levels of 25-hydroxyvitamin D directly were related to bone mineral density. When the level was 30 ng/mL or less, there was a significant decrease in intestinal calcium absorption and bone mineral density.6

Diagnostic evaluation: The “gold standard” for diagnosis of osteoporosis is bone mineral density (BMD) testing. The National Osteoporosis Foundation (NOF), the American Association of Clinical Endocrinologists (AACE), and the North American Menopause Society (NAMS) all agree, however, that the history of fragility fracture is diagnostic for osteoporosis, and all recommend initiating pharmacologic therapy in patients with this type of fracture. BMD testing is then used to track a patient’s response to therapy rather than as a diagnostic test.7 An osteoporosis diagnosis should always trigger a history, physical, and evaluation to identify the underlying cause.

Laboratory testing: All patients with osteoporosis should receive laboratory testing. As a baseline obtain chemistry studies, glucose, liver enzymes, albumin, total protein, alkaline phosphatase, and a complete blood count. Also, obtain a 25-hydroxyvitamin D level to help direct the immediate treatment.

Management

Patients with previous fractures related to osteoporosis require aggressive nonpharmacologic and pharmacologic therapy. Physicians should encourage lifestyle changes that include regular weight-bearing exercise, fall prevention, and discontinuation of tobacco products. Minimizing alcohol ingestion and sedating medications also is recommended. Physical therapy should evaluate gait and balance prior to discharge. Hip protectors may be beneficial, although the data to support this practice is sparse. It also is helpful to arrange a home nurse/therapy visit to assess for hazards in the home that might contribute to falls.

In addition, patients should have adequate calcium and vitamin D intake. The Women’s Health Initiative study showed that calcium with vitamin D use lead to a statistically significant improvement in hip bone density and a 29% reduction in the risk of hip fracture.3 The NOF recommends adults 50 and older have a daily intake of 1,200 mg of calcium and 800 to 1,000 IU of vitamin D. While no definitive data exist to guide the doses of vitamin D and calcium for osteoporosis treatment, it’s reasonable to tailor treatment to the patient’s 25-hydroxyvitamin level.

Specifically, initiate bisphosphonates along with calcium and vitamin D in patients with mild vitamin D deficiency (levels 10 to 30 ng/mL). Patients with severe vitamin D deficiency (<10 ng/mL) should have two to three months of aggressive vitamin D replacement prior to beginning a bisphosphonate. Vitamin D deficiency often is associated with impaired bone mineralization, which potentially could worsen with a bisphosphonate.

Some of the FDA-approved pharmacologic therapies for osteoporosis include antiresorptive bisphosphonates, such as alendronate, risedronate, ibandronate, zoledronic acid, and raloxifene, as well as the human parathyroid hormone teriparatide. Morin et al., performed a population-based, retrospective cohort study using administrative databases to identify patients hospitalized for a hip fracture. They found patients exposed to antiresorptives had a 26% reduction in the rate of recurrent fractures.8

Bisphosphonates are the current first-line treatment of choice unless the clinical situation warrants otherwise. Do not prescribe oral bisphosphonates for patients with hypocalcemia, creatinine clearance lower than 30mL/min, esophageal stricture, or for those who cannot remain upright for 30 minutes.7

Recently, the use of the IV bisphosphonate zolendronic acid within three months of a hip fracture was evaluated. The study randomized approximately 2,100 patients to zolendronic acid 5 mg IV or placebo annually and followed them for a median of 1.9 years. Both groups received vitamin D and calcium supplementation. Those patients using zolendronic acid saw a statistically significant reduction in overall fracture (13.9% vs. 8.6%) and mortality (13.3% vs. 9.6%) rates. While these data support the timely use of bisphosphonate therapy, it is notable that only patients who refused or couldn’t tolerate oral bisphosphonate therapy received the drug, and it was generally not started in the hospital. Still, it’s reasonable to suspect that these beneficial effects would occur even if started in the hospital, as long as the vitamin D and calcium levels did not contraindicate commencement.9

Physicians Don’t Recognize Osteoporosis

In 2000, Kamel et al. retrospectively studied the charts of 170 patients age 65 and older who were hospitalized with a hip fracture, and found that fewer than 5% had been diagnosed with or treated for osteoporosis.7 Follin et al., noted similar results in 2003, reporting that only 14% of the patients were diagnosed with osteoporosis prior to discharge and 75% of patients received no therapy.10

Follin et al., also noted patients who received a diagnosis of osteoporosis prior to discharge were more likely to receive therapy. Sixty-five percent of patients diagnosed with osteoporosis received treatment as opposed to 20% of those not diagnosed. They surmised the lack of treatment may relate to the lack of recognition that a fragility fracture often means osteoporosis.10

Hospitalist Consult, Treatment of Osteoporosis in Hip Fracture Patients

A 2003 retrospective analysis from a university-based academic hospital aimed to determine whether hospitalist consultation during admission for a hip fracture resulted in improved treatment of osteoporosis. The results indicated 29% of patients received treatment for osteoporosis at the time of discharge. Twenty percent received calcium, and only 7% received a bisphosphonate. Those who received hospitalist consultation did not have a significant improvement in osteoporosis treatment, thus representing a huge missed opportunity.11

Back to the Case

You recognize that, because your patient has sustained a fragility fracture, she has osteoporosis and you wish to initiate treatment before she leaves the hospital. Her 25-hydroxyvitamin D level is 18 ng/mL. You commence 50,000 units of vitamin D once weekly and advise that she have her vitamin D level checked again in three months by her primary care provider. She has no contraindications, thus you also initiate a bisphosphonate and remind her to take 1,200 mg of calcium daily.

You encourage smoking cessation, decreased alcohol use, a simplified medication regimen, and weight-bearing exercises in the future. In addition, you ensure she has the proper gait stability items at discharge. You arrange a visiting nurse/therapist to assess her home for fall risks. Lastly, you schedule an outpatient bone mineral density scan and arrange a follow-up with her primary care provider. TH

In the late 1990s, inpatient care, nursing home care, and outpatient services associated with hip fractures totaled approximately $14 billion annually. These costs are predicted to reach $50 billion by the year 2040.3 Not surprisingly, second hip fractures are common, with up to 12% of patients suffering another fracture within one year of follow up.1 Risk of morbidity and mortality are even higher after a second hip fracture.

In most experts’ opinions, a fragility fracture indicates osteoporosis and warrants treatment—regardless of bone densitometry findings. Still, multiple studies have shown patients who sustain a hip fracture frequently are not diagnosed, evaluated, or treated for osteoporosis.4 This is analogous to treating an acute coronary syndrome without initiating treatment for a patient’s hypertension and hyperlipidemia prior to discharge. As such, providers clearly are missing an opportunity to begin effective measures at a critical stage in the disease.

Data Review

Physiology of bone strength: Bone minerals—in particular calcium hydroxyapatite—contribute to bone strength by making bone a hard tissue. Collagen adds flexibility and gives bone the ability to absorb energy. The degree of bone mineralization and the number of collagen crosslinks help determine how much stress a bone can tolerate before it breaks. Further, in response to daily stressors, bone accumulates microcracks. Remodeling is then accomplished by bone resorption and formation.5

Estrogen plays an important role in normal remodeling by controlling osteoclast action. Thus, estrogen deficiency leads to prolonged osteoclast activity and increased rates of bone resorption. This explains why bone remodeling typically favors bone resorption later in life and why women are at greatest risk for fracture.5

Vitamin D and calcium: Vitamin D, produced by the skin or ingested, is transported in the circulation by a binding protein to the liver, where it is converted to 25-hydroxyvitamin D. This form is inactive and must be converted by the kidneys to the active form, 1,25-dihydroxyvitamin D. The active form is needed for absorption of renal and intestinal calcium.6

Without vitamin D only 10% to 15% of dietary calcium is absorbed. In one study, serum levels of 25-hydroxyvitamin D directly were related to bone mineral density. When the level was 30 ng/mL or less, there was a significant decrease in intestinal calcium absorption and bone mineral density.6

Diagnostic evaluation: The “gold standard” for diagnosis of osteoporosis is bone mineral density (BMD) testing. The National Osteoporosis Foundation (NOF), the American Association of Clinical Endocrinologists (AACE), and the North American Menopause Society (NAMS) all agree, however, that the history of fragility fracture is diagnostic for osteoporosis, and all recommend initiating pharmacologic therapy in patients with this type of fracture. BMD testing is then used to track a patient’s response to therapy rather than as a diagnostic test.7 An osteoporosis diagnosis should always trigger a history, physical, and evaluation to identify the underlying cause.

Laboratory testing: All patients with osteoporosis should receive laboratory testing. As a baseline obtain chemistry studies, glucose, liver enzymes, albumin, total protein, alkaline phosphatase, and a complete blood count. Also, obtain a 25-hydroxyvitamin D level to help direct the immediate treatment.

Management

Patients with previous fractures related to osteoporosis require aggressive nonpharmacologic and pharmacologic therapy. Physicians should encourage lifestyle changes that include regular weight-bearing exercise, fall prevention, and discontinuation of tobacco products. Minimizing alcohol ingestion and sedating medications also is recommended. Physical therapy should evaluate gait and balance prior to discharge. Hip protectors may be beneficial, although the data to support this practice is sparse. It also is helpful to arrange a home nurse/therapy visit to assess for hazards in the home that might contribute to falls.

In addition, patients should have adequate calcium and vitamin D intake. The Women’s Health Initiative study showed that calcium with vitamin D use lead to a statistically significant improvement in hip bone density and a 29% reduction in the risk of hip fracture.3 The NOF recommends adults 50 and older have a daily intake of 1,200 mg of calcium and 800 to 1,000 IU of vitamin D. While no definitive data exist to guide the doses of vitamin D and calcium for osteoporosis treatment, it’s reasonable to tailor treatment to the patient’s 25-hydroxyvitamin level.

Specifically, initiate bisphosphonates along with calcium and vitamin D in patients with mild vitamin D deficiency (levels 10 to 30 ng/mL). Patients with severe vitamin D deficiency (<10 ng/mL) should have two to three months of aggressive vitamin D replacement prior to beginning a bisphosphonate. Vitamin D deficiency often is associated with impaired bone mineralization, which potentially could worsen with a bisphosphonate.

Some of the FDA-approved pharmacologic therapies for osteoporosis include antiresorptive bisphosphonates, such as alendronate, risedronate, ibandronate, zoledronic acid, and raloxifene, as well as the human parathyroid hormone teriparatide. Morin et al., performed a population-based, retrospective cohort study using administrative databases to identify patients hospitalized for a hip fracture. They found patients exposed to antiresorptives had a 26% reduction in the rate of recurrent fractures.8

Bisphosphonates are the current first-line treatment of choice unless the clinical situation warrants otherwise. Do not prescribe oral bisphosphonates for patients with hypocalcemia, creatinine clearance lower than 30mL/min, esophageal stricture, or for those who cannot remain upright for 30 minutes.7

Recently, the use of the IV bisphosphonate zolendronic acid within three months of a hip fracture was evaluated. The study randomized approximately 2,100 patients to zolendronic acid 5 mg IV or placebo annually and followed them for a median of 1.9 years. Both groups received vitamin D and calcium supplementation. Those patients using zolendronic acid saw a statistically significant reduction in overall fracture (13.9% vs. 8.6%) and mortality (13.3% vs. 9.6%) rates. While these data support the timely use of bisphosphonate therapy, it is notable that only patients who refused or couldn’t tolerate oral bisphosphonate therapy received the drug, and it was generally not started in the hospital. Still, it’s reasonable to suspect that these beneficial effects would occur even if started in the hospital, as long as the vitamin D and calcium levels did not contraindicate commencement.9

Physicians Don’t Recognize Osteoporosis

In 2000, Kamel et al. retrospectively studied the charts of 170 patients age 65 and older who were hospitalized with a hip fracture, and found that fewer than 5% had been diagnosed with or treated for osteoporosis.7 Follin et al., noted similar results in 2003, reporting that only 14% of the patients were diagnosed with osteoporosis prior to discharge and 75% of patients received no therapy.10

Follin et al., also noted patients who received a diagnosis of osteoporosis prior to discharge were more likely to receive therapy. Sixty-five percent of patients diagnosed with osteoporosis received treatment as opposed to 20% of those not diagnosed. They surmised the lack of treatment may relate to the lack of recognition that a fragility fracture often means osteoporosis.10

Hospitalist Consult, Treatment of Osteoporosis in Hip Fracture Patients

A 2003 retrospective analysis from a university-based academic hospital aimed to determine whether hospitalist consultation during admission for a hip fracture resulted in improved treatment of osteoporosis. The results indicated 29% of patients received treatment for osteoporosis at the time of discharge. Twenty percent received calcium, and only 7% received a bisphosphonate. Those who received hospitalist consultation did not have a significant improvement in osteoporosis treatment, thus representing a huge missed opportunity.11

Back to the Case

You recognize that, because your patient has sustained a fragility fracture, she has osteoporosis and you wish to initiate treatment before she leaves the hospital. Her 25-hydroxyvitamin D level is 18 ng/mL. You commence 50,000 units of vitamin D once weekly and advise that she have her vitamin D level checked again in three months by her primary care provider. She has no contraindications, thus you also initiate a bisphosphonate and remind her to take 1,200 mg of calcium daily.

You encourage smoking cessation, decreased alcohol use, a simplified medication regimen, and weight-bearing exercises in the future. In addition, you ensure she has the proper gait stability items at discharge. You arrange a visiting nurse/therapist to assess her home for fall risks. Lastly, you schedule an outpatient bone mineral density scan and arrange a follow-up with her primary care provider. TH

Case

A 66-year-old female with a pack-a-day smoking habit is admitted to orthopedics with a hip fracture following a fall in her home. You are consulted to perform a pre-operative risk assessment and manage her heart failure. The following day, she undergoes an open reduction and internal fixation and does well following the surgery. She is scheduled to be discharged for rehabilitation in two days. She will continue taking her cardiac medications and the narcotics (as needed) for pain. What else can you recommend to reduce her chances of suffering another hip fracture?

Observation care provides a mechanism to evaluate and treat patients without the resource utilization and financial responsibility associated with an inpatient admission. Hospitalists may not understand the billing compliance risk and corresponding revenue implications when observation services (OBS) are not captured correctly.

Are OBS best reported with observation care codes (99218-99220, 99234-99236), office visit codes (99201-99215), or initial hospital care codes (99221-99223)? Code selection depends upon the patient’s registered status, the nature of the provided service, and the length of stay. Review the following information before reporting OBS to ensure an accurate claim submission.

Attending Physician Responsibilities

The physician-documented reason for observation substantiates the medical necessity for the OBS admission. Contractors often evaluate medical records to determine the consistency between the physician order (physician intent), the services actually provided (inpatient or outpatient), and the medical necessity of those services, including the medical appropriateness of the inpatient or observation stay.

Certain diagnoses and procedures generally do not support an inpatient admission and fall within the definitions of outpatient observation. Uncomplicated presentations of chest pain (rule out MI), mild asthma/COPD, mild CHF, syncope and decreased responsiveness, atrial arrhythmias, and renal colic all frequently are associated with the expectation of a brief (less than 24-hour) stay unless serious pathology is uncovered.2 Situations that do not meet the criteria for observation care are considered “not medically necessary” and separate payment is not permitted. Examples of circumstances that lack medical necessity include:

• Outpatient blood administration;
• Lack of/delay in patient transportation;
• Provision of a medical exam for patients who do not require skilled support;
• Routine preparation prior to and recovery after diagnostic testing;
• Routine recovery and post-operative care after ambulatory surgery;
• When used for the convenience of the physician, patient or patient’s family;
• While awaiting transfer to another facility;
• Duration of care exceeding 48 hours;
• When an overnight stay is planned prior to diagnostic testing;
• Standing orders following outpatient surgery;
• Services that would normally require inpatient stay;
• No physicians order to admit to observation;
• Observation following an uncomplicated treatment or procedure;
• Services that are not reasonable and necessary for care of the patient;
• Services provided concurrently with chemotherapy; and
• Inpatients discharged to outpatient observation status.3

The attending physician of record assumes responsibility for the patient’s admission to observation and is permitted to report observation care codes. In addition to the reason for admission, a medical record involving the observation stay must include dated and timed physician admitting orders outlining the care plan, physician progress notes, and discharge orders. This documentation must be added to any other record prepared as a result of an emergency department or outpatient clinic encounter. If physicians other than the admitting physician/group (i.e., physicians in different specialties) provide services to the patient during observation, they must use the appropriate outpatient visit (e.g., 99214) or consultation code (e.g., 99244).

Length of Stay⁴

In general, the duration of observation care services typically does not exceed 24 hours, although in some circumstances patients may require a second day. Observation care for greater than 48 hours without inpatient admission is not considered medically necessary but may be payable after medical review. When the stay spans two calendar days, physician billing is straightforward: Select an initial observation care code (99218-99220) for calendar day one and the observation discharge code (99217) for day two. Only the admitting physician/group may report the discharge service, when applicable. Documentation must demonstrate a face-to-face encounter by the physician for each date of service.

Should the stay only constitute one calendar day, the duration of care becomes a crucial factor in determining the code category. Standard OBS codes (99218-99220) are applicable if the patient stay is less than eight hours on any given date. The OBS discharge code (99217) is not reported in this instance, although the documentation should reflect the attending physician’s written order and appropriate discharge plan. Alternately, same day admit/discharge codes (99234-99236) apply to single-day stays lasting more than eight hours. The OBS discharge code (99217) also is not reported in this instance. Documentation must identify, at a minimum:

• Duration of the stay;
• Presence by the billing physician; and
• Physician performance of each service (i.e., both an admission and discharge note).

Inpatient Admission^1,4-5

Sometimes the patient requires inpatient admission after initially being placed in observation. If the inpatient admission occurs on the same day as the OBS admission, only one service is reported (e.g., 99222). The physician need not redocument a complete history and physical (H&P) but merely write the new order for admission and update the OBS assessment with any relevant, new information.

Should the inpatient admission occur on the second calendar day of the OBS stay, the physician is able to report the initial observation care code (e.g., 99219) on day one, and the initial inpatient care code (e.g., 99223) on day two. However, the physician must meet the documentation guidelines for initial hospital care and redocument the H&P associated with the reported visit level. In the case of 99223, the physician must document a comprehensive history (only referring to the previous review of systems and histories, while rewriting the history of present illness) and high complexity decision making. If the physician chooses not to document to this extent, a subsequent hospital care code (99231-99233) is reasonable because the episode of care is a continuation from the observation phase.

Beware that some insurers may change the patient’s status for the entire episode of care. In other words, the conversion to inpatient status occurs on day two of the patient stay, but the insurer may convert the entire stay, including day one, to an inpatient status. Should this happen, the physician is responsible for reporting the visit category that corresponds with the patient’s status. Inpatient services codes are required for claim submission when the patient stay qualifies as an inpatient admission. Because these conversions occur with some frequency, it is advisable to hold claims intended for observation patients until the correct patient status can be confirmed by the utilization review team, and communicated to the physician.

Length of Stay⁴

In general, the duration of observation care services typically does not exceed 24 hours, although in some circumstances patients may require a second day. Observation care for greater than 48 hours without inpatient admission is not considered medically necessary but may be payable after medical review. When the stay spans two calendar days, physician billing is straightforward: Select an initial observation care code (99218-99220) for calendar day one and the observation discharge code (99217) for day two. Only the admitting physician/group may report the discharge service, when applicable. Documentation must demonstrate a face-to-face encounter by the physician for each date of service.

Should the stay only constitute one calendar day, the duration of care becomes a crucial factor in determining the code category. Standard OBS codes (99218-99220) are applicable if the patient stay is less than eight hours on any given date. The OBS discharge code (99217) is not reported in this instance, although the documentation should reflect the attending physician’s written order and appropriate discharge plan. Alternately, same day admit/discharge codes (99234-99236) apply to single-day stays lasting more than eight hours. The OBS discharge code (99217) also is not reported in this instance. Documentation must identify, at a minimum:

• Duration of the stay;
• Presence by the billing physician; and
• Physician performance of each service (i.e., both an admission and discharge note).

Inpatient Admission^1,4-5

Sometimes the patient requires inpatient admission after initially being placed in observation. If the inpatient admission occurs on the same day as the OBS admission, only one service is reported (e.g., 99222). The physician need not redocument a complete history and physical (H&P) but merely write the new order for admission and update the OBS assessment with any relevant, new information.

Should the inpatient admission occur on the second calendar day of the OBS stay, the physician is able to report the initial observation care code (e.g., 99219) on day one, and the initial inpatient care code (e.g., 99223) on day two. However, the physician must meet the documentation guidelines for initial hospital care and redocument the H&P associated with the reported visit level. In the case of 99223, the physician must document a comprehensive history (only referring to the previous review of systems and histories, while rewriting the history of present illness) and high complexity decision making. If the physician chooses not to document to this extent, a subsequent hospital care code (99231-99233) is reasonable because the episode of care is a continuation from the observation phase.

Beware that some insurers may change the patient’s status for the entire episode of care. In other words, the conversion to inpatient status occurs on day two of the patient stay, but the insurer may convert the entire stay, including day one, to an inpatient status. Should this happen, the physician is responsible for reporting the visit category that corresponds with the patient’s status. Inpatient services codes are required for claim submission when the patient stay qualifies as an inpatient admission. Because these conversions occur with some frequency, it is advisable to hold claims intended for observation patients until the correct patient status can be confirmed by the utilization review team, and communicated to the physician.

Observation care provides a mechanism to evaluate and treat patients without the resource utilization and financial responsibility associated with an inpatient admission. Hospitalists may not understand the billing compliance risk and corresponding revenue implications when observation services (OBS) are not captured correctly.

Are OBS best reported with observation care codes (99218-99220, 99234-99236), office visit codes (99201-99215), or initial hospital care codes (99221-99223)? Code selection depends upon the patient’s registered status, the nature of the provided service, and the length of stay. Review the following information before reporting OBS to ensure an accurate claim submission.

Attending Physician Responsibilities

The physician-documented reason for observation substantiates the medical necessity for the OBS admission. Contractors often evaluate medical records to determine the consistency between the physician order (physician intent), the services actually provided (inpatient or outpatient), and the medical necessity of those services, including the medical appropriateness of the inpatient or observation stay.

Certain diagnoses and procedures generally do not support an inpatient admission and fall within the definitions of outpatient observation. Uncomplicated presentations of chest pain (rule out MI), mild asthma/COPD, mild CHF, syncope and decreased responsiveness, atrial arrhythmias, and renal colic all frequently are associated with the expectation of a brief (less than 24-hour) stay unless serious pathology is uncovered.2 Situations that do not meet the criteria for observation care are considered “not medically necessary” and separate payment is not permitted. Examples of circumstances that lack medical necessity include:

• Outpatient blood administration;
• Lack of/delay in patient transportation;
• Provision of a medical exam for patients who do not require skilled support;
• Routine preparation prior to and recovery after diagnostic testing;
• Routine recovery and post-operative care after ambulatory surgery;
• When used for the convenience of the physician, patient or patient’s family;
• While awaiting transfer to another facility;
• Duration of care exceeding 48 hours;
• When an overnight stay is planned prior to diagnostic testing;
• Standing orders following outpatient surgery;
• Services that would normally require inpatient stay;
• No physicians order to admit to observation;
• Observation following an uncomplicated treatment or procedure;
• Services that are not reasonable and necessary for care of the patient;
• Services provided concurrently with chemotherapy; and
• Inpatients discharged to outpatient observation status.3

The attending physician of record assumes responsibility for the patient’s admission to observation and is permitted to report observation care codes. In addition to the reason for admission, a medical record involving the observation stay must include dated and timed physician admitting orders outlining the care plan, physician progress notes, and discharge orders. This documentation must be added to any other record prepared as a result of an emergency department or outpatient clinic encounter. If physicians other than the admitting physician/group (i.e., physicians in different specialties) provide services to the patient during observation, they must use the appropriate outpatient visit (e.g., 99214) or consultation code (e.g., 99244).

CMS has taken up the e-prescribing torch. In July, the agency announced a preliminary program to promote widespread adoption of electronic prescribing.

E-prescribing is a natural goal for CMS; it has been proven to improve quality of care, reduce medication errors, increase efficiency, and lower administrative costs. Kerry Weems, the acting CMS administrator, says an all-electronic prescribing system could save Medicare as much as $156 million over five years—largely through improved quality care.

Though details on the e-prescribing plan are not yet decided, CMS has revealed that beginning in 2009 (and for the next four years) it will provide incentive payments to physicians who are “successful electronic prescribers.”

Details to Be Determined

The e-prescribing plan will be included in the Physician Quality Reporting Initiative (PQRI), with guidelines included in the 2009 PQRI. (How the new plan will work with the current PQRI e-prescribing measure is one of the unknown details.)

Weems says CMS will use its standard rule-making process to shape the e-prescribing plan. Therefore, details of the incentives program will not be available until this fall, when Medicare releases its final rule on the 2009 physician fee schedule. According to Weems, the 2009 fee schedule and PQRI will clarify some murkiness. “They will be specific about what constitutes e-prescribing, including the extent and reporting of what needs to be done through PQRI,” he says.

Rewards, Then Possible Punishments

Physicians can start reporting on e-prescribing Jan. 1, and those who do will reap the benefits. Patrick Conway, MD, MSc, a hospitalist, an assistant professor at Cincinnati Children’s Hospital Medical Center, and a 2007-2008 White House Fellow working in the Department of Health and Human Services (HHS), says initial discussions about promoting e-prescribing included talk of an incentive-based plan.

“It’s my opinion that, for physicians, it’s beneficial to start with a reward or carrot rather than a punishment,” he says. “And generally, CMS has approached physician programs with this method—like the PQRI.”

The current plan’s outlines indicates that in 2009 and 2010, physicians who successfully report on e-prescribing will receive an incentive payment of up to 2% of their total Medicare allowed charges, matching the maximum bonus they can earn under the regular PQRI. Payment will be additive, so a physician can earn up to 4% (2% for PQRI and 2% for e-prescribing.)

The e-prescribing incentive will drop to 1% in 2011 and 2012, and to 0.5% incentive payment in 2013. After 2013, the carrot is replaced with a stick, and those who do not use e-prescribing will suffer a reduction in payment.

Cost Concerns

CMS estimates the cost of adopting e-prescribing will be approximately $3,000 per individual prescriber. This includes equipment, training, and program maintenance. That can add up to a sizeable expense—particularly for small groups. For that reason, the agency promises a built-in hardship exemption for small practices and others who prove they cannot afford to adopt e-prescribing.

Also, some funding is available: Dr. Conway says CMS has a financial-incentive program for electronic health records, many of which include e-prescribing. “The CMS Electronic Health Records Demonstration is a $150 million program that will provide funds to 1,200 physician practices to adopt this technology,” he says. “They’re currently recruiting practices.” Details on the demonstration are available at www.cms.hhs.gov/DemoProjectsEvalRpts/.

Will Hospitalists Participate?

Until details of the e-prescribing program are published, no one can say whether the plan will encompass hospitalists. However, Dr. Conway says, “I think this plan is conceptually relevant to hospitalists: It’s possible that hospitalists will be able to participate in the current plan. We don’t know yet. But CMS will continue to push forward on initiatives that increase quality and decrease costs, including e-prescribing. They’ll support electronic health records, whether this particular initiative applies to hospitals or not.”

Even if it turns out hospital medicine groups can’t reap incentive payments from the new plan, Dr. Conway hopes they still will adopt the technology. “Computerized physician order entry (CPOE) and e-prescribing have the potential to decrease errors and increase the quality of care,” he says. “Therefore, I would encourage hospitals and hospitalists to implement electronic health records with computerized order entry and e-prescribing when possible.”

He says the real benefit to hospitals seeking to improve quality and reduce error is not the electronic transmission of prescriptions to the pharmacy, but CPOE. “Most evidence of increased quality is around computerized physician order entry, which includes decision support at the time of the order,” he points out. “One could argue that you could have an incentive for hospitals that utilize CPOE, but I have no idea if CMS will pursue that.”

Next Steps

On Oct. 6-7 CMS will host a conference on the complete e-prescribing plan for pharmacists and physicians in Boston. For details, check the CMS site at www.cms.hhs.gov/eprescribing or www.cms.hhs.gov/pqri.

Dr. Conway thinks the meeting is a good next step for CMS. “I believe it’s very important to engage frontline providers and stakeholders, so the concept of holding a conference to ensure the design of the program is understood, and to get buy-in from the people participating, is a wise choice,” he says.

In the next few months, physicians likely will be inundated with information on e-prescribing processes under the CMS plan. Stay abreast of the latest information through the CMS Web site and, if it turns out, hospitalists can actively participate in the plan, through the SHM Web site at www.hospitalmedicine.org. TH

If you’re in an HM leadership position, don’t be surprised if you’re asked to be a mentor for a less-experienced hospitalist. Why should you voluntarily spend valuable time sharing your guidance and advice? Because to lead is to mentor, and when you dive into the process it rewards all parties involved.

To Lead Is to Mentor

Whether you were just promoted or you’re a leadership veteran approached for the first time by an eager new hospitalist, don’t hesitate to add mentoring to your schedule and responsibilities.

“When you start out as a leader, you get where you want to go by being a mentor,” says Eric E. Howell, MD, director of Collaborative Inpatient Medicine Service, Department of Medicine, Johns Hopkins Bayview Medical Center, Baltimore and faculty for SHM’s Leadership Academy. “You gather disciples, as it were, who will then see you as a leader and support you as a good leadership choice.”

Not only that, but mentoring can add to your skill set as a leader, says Joan C. Faro, MD, FACP, MBA, chief medical officer at John T. Mather Memorial Hospital, Port Jefferson, N.Y. “If you’re interested in developing leadership skills, it’s one of those things you need to do, and do well. If you can’t mentor, then you really can’t lead.”

Plus, when you mentor, you get to feel the reward inherent in helping a young physician whose shoes you once filled. “It’s like raising a kid,” says Dr. Faro. “You want to do a good job because you want to see someone succeed.” This is especially true for mentoring relationships within your HM group.

That means fully flushing out the program and dedicating the time necessary to make it a success. “If you are the de facto leader of a group, you have some obligation to people interested in career development,” says Dr. Howell. “I think it’s part of the job to help advance those people.”

The Ground Rules

Any new mentoring arrangement should start with a discussion of expectations, responsibilities, time frames, and communication. What are the mentee’s expectations for the relationship? How much time can you, the mentor, offer?

Whether the arrangement is formal (a director mentoring a new hire) or casual (an established hospitalist asking a conference speaker for a long-distance mentoring relationship), ground rules are important, Dr. Howell insists. “The mentoring relationship can be established informally, but it’s worthwhile to set some rules on responsibilities: How is the feedback going to come, how frank and honest do you want to be, when should we meet? …Rules will depend on the relationship and on the individuals involved.”

If nothing else, agree to how frequently you will meet or speak. “It could be quarterly or it could be weekly,” says Dr. Howell. “Face time is important, but e-mail and phone calls will work, too, as long as you’ve established some ground rules about this. If the mentee expects a face-to-face meeting and you’re e-mailing your answers, that could be a problem. So you need to establish how you’re going to communicate.”

Those meetings can add up to a sizeable commitment. How much time, exactly, should a new mentor expect to devote to this aspect of leadership? “It varies widely,” Dr. Howell admits. “But I will say that many younger mentees require much more time than older mentors expect. If they’re struggling or haven’t found their stride yet, it can require several hours a week, which is a lot for a busy person’s schedule. But many relationships can be handled weekly or monthly.”

Dr. Faro, who has mentored many hospitalists within her organization, says, “You need to build the relationship; you need enough contact time so that you can understand each other.” For her, that amounts to 40 to 50 hours of getting-to-know-you time, she says. “After that, maybe an hour a week.”

Tailor Mentoring

Dr. Faro tailors her guidance to the personality, capabilities, and level of independence of each person she mentors—hence her lengthy initial time frame.

“You need to start with setting up a clear set of goals and outcomes,” she says. “They really need to know what they’re doing and why they’re doing it. So, set up a plan with specific time frames. It’s your job to determine how independent they are; you may end up giving them goals rather than them stating what they’re going to do.”

For example, she might tell one mentee to develop an order set for patients with syncope, and expect a document by an agreed-upon deadline. She might give another individual the same assignment, but walk that person through each step—within reason. “You can’t do it for them, or they’re not going to learn,” she maintains.

Each completed task is met with constructive criticism. How well was the task done? Did the physician leave out anything? If Dr. Faro senses that more guidance is necessary, she steps up her level of involvement.

What Makes a Successful Mentor?

Dr. Faro understands the mentor/mentee process because she’s been part of it for so long. How can you get to that point? Simply agreeing to be a mentor and having regular meetings with your mentee doesn’t necessarily mean you’re doing a good job.

“Good mentors probably listen more than they talk,” explains Dr. Howell. “For many people, if they can talk it out, they will reach their own conclusions and that’s much more powerful than being told something. That ‘Aha!’ moment is a big career moment.”

He also believes strong mentors can give even non-hospitalists helpful career advice. “Good mentors are able to step out of their own shoes and look at the unique situation of the other person, and give advice tailored to that situation,” he explains. “You have to be altruistic in your mentoring; you can’t do it for your own needs.”

Successful mentors also understand their mentees. For example, mentees in leadership positions should receive advice about how to invest in themselves and their careers. “I always recommend SHM’s Leadership Academy, as well as several books, including Getting to Yes and Good to Great to improve themselves as leaders,” says Dr. Howell.

Finally, a mentor who does the job well understands when the relationship isn’t working. If this is the case, “be up-front and honest, and if possible, point that person to another mentor,” Dr. Howell says. “If you can introduce them and get them started, that’s best. You can also share a mentee with someone else; you can each handle different areas. I have many different mentors in different areas. It’s more productive that way.” TH

Jane Jerrard also writes “Public Policy” for The Hospitalist.

If you’re in an HM leadership position, don’t be surprised if you’re asked to be a mentor for a less-experienced hospitalist. Why should you voluntarily spend valuable time sharing your guidance and advice? Because to lead is to mentor, and when you dive into the process it rewards all parties involved.

To Lead Is to Mentor

Whether you were just promoted or you’re a leadership veteran approached for the first time by an eager new hospitalist, don’t hesitate to add mentoring to your schedule and responsibilities.

“When you start out as a leader, you get where you want to go by being a mentor,” says Eric E. Howell, MD, director of Collaborative Inpatient Medicine Service, Department of Medicine, Johns Hopkins Bayview Medical Center, Baltimore and faculty for SHM’s Leadership Academy. “You gather disciples, as it were, who will then see you as a leader and support you as a good leadership choice.”

Not only that, but mentoring can add to your skill set as a leader, says Joan C. Faro, MD, FACP, MBA, chief medical officer at John T. Mather Memorial Hospital, Port Jefferson, N.Y. “If you’re interested in developing leadership skills, it’s one of those things you need to do, and do well. If you can’t mentor, then you really can’t lead.”

Plus, when you mentor, you get to feel the reward inherent in helping a young physician whose shoes you once filled. “It’s like raising a kid,” says Dr. Faro. “You want to do a good job because you want to see someone succeed.” This is especially true for mentoring relationships within your HM group.

That means fully flushing out the program and dedicating the time necessary to make it a success. “If you are the de facto leader of a group, you have some obligation to people interested in career development,” says Dr. Howell. “I think it’s part of the job to help advance those people.”

The Ground Rules

Any new mentoring arrangement should start with a discussion of expectations, responsibilities, time frames, and communication. What are the mentee’s expectations for the relationship? How much time can you, the mentor, offer?

Whether the arrangement is formal (a director mentoring a new hire) or casual (an established hospitalist asking a conference speaker for a long-distance mentoring relationship), ground rules are important, Dr. Howell insists. “The mentoring relationship can be established informally, but it’s worthwhile to set some rules on responsibilities: How is the feedback going to come, how frank and honest do you want to be, when should we meet? …Rules will depend on the relationship and on the individuals involved.”

If nothing else, agree to how frequently you will meet or speak. “It could be quarterly or it could be weekly,” says Dr. Howell. “Face time is important, but e-mail and phone calls will work, too, as long as you’ve established some ground rules about this. If the mentee expects a face-to-face meeting and you’re e-mailing your answers, that could be a problem. So you need to establish how you’re going to communicate.”

Those meetings can add up to a sizeable commitment. How much time, exactly, should a new mentor expect to devote to this aspect of leadership? “It varies widely,” Dr. Howell admits. “But I will say that many younger mentees require much more time than older mentors expect. If they’re struggling or haven’t found their stride yet, it can require several hours a week, which is a lot for a busy person’s schedule. But many relationships can be handled weekly or monthly.”

A healthy 30-year-old female presented to the urgent care center with confusion, tremor, and a blood pressure of 160/110 mm Hg. She had no history of hypertension, diabetes, dyslipidemia, renal dysfunction, or smoking. A basic metabolic panel revealed no abnormalities.

Her medication history revealed use of paroxetine (20 mg) subsequent to a depressive episode two years prior. A source of the hypertension was not identified, and she was sent home without further follow-up. The next day, she was admitted to the hospital via the emergency department for stroke symptoms, including numbness and weakness on her right side (extremities and face), with confusion and diplopia. She remained hospitalized for four days during which time she continued to experience transient ischemic attacks. The paroxetine eventually was discontinued. She subsequently has recovered without negative sequelae.

Serotonin syndrome is a consequence of a hyperserotonergic state, due to drug-induced serotonin intensification.1 It can be mild or life-threatening and is characterized by a triad of clinical manifestations: mental status changes, autonomic hyperactivity, and neuromuscular abnormalities.2 Clinicians may miss mild symptoms, such as diarrhea, tremor, tachycardia, diaphoresis, or mydriasis. This can result in an increase in the dose of the causative agent or addition of a serotonergic agent, thus yielding a worsening clinical decline.3

Patients with a more severe clinical presentation include those with severe hypertension (as in the case above), tachycardia, muscular rigidity, and shock. Laboratory abnormalities may be present if the patient develops subsequent rhabdomyolysis, seizures, metabolic acidosis, or renal failure. Serotonin syndrome is diagnosed based on the patient’s presentation, history, and physical examination. It should be differentiated from neuroleptic malignant syndrome, which has a similar presentation.4

Serotonergic agents used alone, or in combination, may lead to serotonin syndrome.5 A recent report discussed the appearance of serotonin syndrome in patients receiving only sumatriptan. Other offenders include such antidepressants as monoamine oxidase inhibitors, buspirone, citalopram, clomipramine, escitalopram, fluoxetine, fluvoxamine, nefazodone, paroxetine, sertraline, trazodone, and venlafaxine. Other causative agents include dextromethorphan, fentanyl, granisetron, levodopa, linezolid, lithium, meperidine, metoclopramide, ondansetron, pentazocine, sibutramine, sumatriptan, tramadol, valproate, and drugs of abuse (e.g., amphetamines, cocaine, LSD, ecstasy). Additionally, ginseng, St. John’s Wort, and tryptophan have been implicated.

Many of these agents require an adequate washout period prior to beginning other serotonergic agents. Mild to moderately severe cases usually resolve within 24 to 72 hours, although most resolve within a week depending on the half-life of the medication. Serotonin syndrome carries an 11% mortality rate and is best managed by stopping the offending agent and providing supportive care. TH

Literature at a Glance

• ICU management by critical care physicians may increase the odds of hospital mortality
• Iatrogenic drug overdose common among patients with renal insufficiency
• An educational effort lowers hospital mortality for severe sepsis and septic shock
• SSRI and problem-solving therapy prevents post-stroke depression
• Stop orders for Foley catheters reduce the duration of inappropriate urinary catheterization
• No thromboembolism risk with interrupting anticoagulation in atrial fibrillation patients undergoing surgery
• Obese patients may be initially under-dosed with vancomycin
• Antipsychotic therapy is associated with short-term serious events in older adults with dementia
• Cardiac troponin is associated with worse outcome in acute heart failure

Does management of ICU patients by critical care physicians reduce mortality?

Background: There is variation in the extent of involvement by critical care physicians in managing patients in ICUs. Several small studies have demonstrated improved outcomes when patients are managed by critical care physicians. This study expanded these findings by examining a national database of multiple ICUs.

Study design: Retrospective database analysis.

Setting: 123 ICUs in 100 U.S. hospitals

Synopsis: Using a national database of ICU patients, 101,832 admissions were analyzed. Controlling for ICU characteristics, patient demographics, and severity of illness (SOI), the impact of critical care management (CCM) on the primary outcome of hospital mortality was analyzed. Patients who received CCM had higher SOI, received more procedures, and had higher mortality rates than those who did not receive CCM. After adjustment for these variables, hospital mortality rates were higher for those patients who received CCM.

Because this was a retrospective analysis, it is not possible to state there was a causal relationship between care by a critical care physician and worse outcome. Other unmeasured clinical differences between the patients receiving CCM and those that did not may have existed that resulted in the higher mortality. Additionally, although the database identified management by a critical care physician, it did not differentiate whether the management was by a full-time intensivist. Therefore, conclusions cannot be made regarding the value of full-time, on-site intensivist management.

Bottom line: Additional analysis is required to determine the value of intensivists in the management of critically ill patients.

Citation: Levy MM, Rapoport J, Lemeshow S, Chalfin DB, Phillips G, Danis M. Association between critical care physician management and patient mortality in the intensive care unit. Ann Int Med 2008; 148: 801-809.

What is the frequency of iatrogenic drug overdose in patients with renal insufficiency?

Background: The Institute of Medicine Report, “To Err is Human” suggested 7,000 deaths occur annually because of medication errors. Renal insufficiency is relatively common in hospitalized patients. Previous studies have suggested overdose of medications is frequent in patients with renal insufficiency. There is a lack of large-scale studies identifying the most commonly overdosed medications and the predictive physician factors for these errors.

Study design: Retrospective observational study.

Setting: A single 1,080-bed tertiary teaching hospital

Synopsis: A clinical data mart was constructed that contained 48 months of prescription data, serum creatinine levels, along with physician characteristics. 28,954 patients with renal insufficiency had 431,119 prescription orders to analyze. 3.5% of drug doses were found excessive. The overdose rate in patients with moderate to severe renal insufficiency was 28.2%. 10 drugs accounted for 85.4% of the overdoses. There was a negative correlation between physician clinical experience and overdose rate.

Study results are limited by the study’s retrospective nature. Further, the prescribed dose was presumed to be the dose actually administered, and there were no data on the actual doses given to patients. The study was limited to a single institution and may not be generalizable.

Bottom line: Iatrogenic drug overdose is quite common among inpatients with renal insufficiency. Only a few drugs are commonly responsible. The physicians’ clinical experience, workload of prescriptions, and patients’ renal function correlated with overdose.

Will a national education program based on the “Surviving Sepsis Campaign” guidelines improve survival and processes of care?

Background: Sepsis is one of the most prevalent diseases and one of the main causes of death among hospitalized patients. Several single-center studies have suggested quality improvement efforts based on the Surviving Sepsis Guidelines were associated with better outcomes.

Study design: Prospective multicenter before-and-after study design.

Setting: 59 medical and surgical ICUs throughout Spain.

Synopsis: 854 patients with severe sepsis were enrolled in the pre–intervention group. The intervention consisted of education on the use of bundles of care. The treatment was organized into two bundles: a resuscitation bundle (six tasks to be performed within six hours) and a management bundle (four tasks to be completed within 24 hours). 1,465 patients were enrolled in the post-training period. Hospital mortality, adherence to the bundles, ICU mortality, 28-day mortality, hospital and ICU length of stay were measured.

Patients in the post-intervention group had lower mortality (44.0% vs. 39.5% P=0.04) and better compliance with the bundles improved. No other outcomes improved. One year later, mortality gains persisted but compliance with the resuscitation bundle had lapsed.

This study did not employ a control group, making it difficult to ascribe the improvement in compliance solely to the training given (some improvement in processes may have occurred independent of the training).

Bottom line: A national education effort to promote bundles of care for severe sepsis and septic shock was associated with improved guideline compliance and lower hospital mortality.

Can SSRI and problem-solving therapy reduce the incidence of depression in non-depressed patients with a recent stroke?

Background: Depression occurs in more than half of previously non-depressed patients after a stroke. Post-stroke depression is associated with impaired recovery and increased mortality.

Study design: A multicenter randomized controlled trial.

Setting: Two urban university-affiliated hospitals and a suburban rehabilitation hospital in the U.S.

Synopsis: 178 patients age 50 to 90 were enrolled within three months of an index stroke in a 12-month trial. The patients were randomized into three groups of a double-blind placebo control comparison of escitalopram with placebo, and non-blinded problem-solving therapy group.

During the period of the trial, patients on escitalopram experienced significant reductions in the incidence of depression versus placebo (23.1% vs. 34.5%). Problem-solving therapy did not result in significant benefit over the placebo.

The study results were limited by several factors. The study did not include all patients with acute stroke, employed a relatively small sample size, used a non-blinded psychological problem-solving therapy group, and had a high drop out rate.

Bottom line: Consider SSRI use to prevent depression in post-stroke patients.

Do stop orders for indwelling urinary catheters reduce the duration of inappropriate urinary catheterization and incidence of urinary tract infection?

Background: About 25% of hospitalized patients have an indwelling urinary catheter inserted, and in 30% to 50% of these patients, urinary catheters are not indicated. Approximately 50% of patients with a catheter inserted for five days or more will develop bacteriuria with about 80% of hospital-acquired urinary tract infections occurring in patients with a urinary catheter.

Study design: A randomized controlled study.

Setting: Three tertiary care hospitals in Ontario, Canada.

Synopsis: 692 patients with indwelling urinary catheters admitted to seven general medical units in three tertiary care hospitals from January 2004 to June 2006 were randomized into two groups: 269 in the stop-order group, and 252 in the usual care group. Patients in the stop-order group had fewer days of inappropriate and total urinary catheter used (2.20 days) compared with the usual care group (3.89 days). There was no difference in the incidence of urinary tract infection between both groups.

Study results were limited by several factors, including a lack of control for exposure of participants to antimicrobials, missing urine cultures, and lack of evaluation of the effect of reducing urinary catheter use on mobility and quality of life. The 1.34-day reduction in the duration of catheterization may not be sufficient to significantly reduce bacteriuria.

Bottom line: Consider using stop orders in all patients with indwelling urinary catheters.

Does interrupting anticoagulation in patients with atrial fibrillation undergoing surgery cause an increased rate of thromboembolism?

Background: There is a known risk of thromboembolism (between 0.5% and 20% annually) in patients with atrial fibrillation. Studies are limited regarding the risk of thromboembolism with holding anticoagulation in the perioperative period for nonvalvular atrial fibrillation. This study attempted to answer this question.

Study design: Prospective cohort.

Setting: Thromboembolism clinic of the Mayo Clinic.

Synopsis: 345 patients with nonvalvular atrial fibrillation whose anticoagulation was perioperatively held were monitored for three months after surgery for thromboembolic events. Warfarin therapy was held for 5.3 days +/- three days before surgery and restarted 1.3 days +/- 3.4 days after surgery. Bridging heparin therapy was used for 204/386 procedures.

Four patients suffered six thromboembolic events; two patients while receiving bridging heparin therapy and two without heparin. The total incidence of thromboembolic events was 1.1%. This is compared with an expected incidence of 0.09% to 2.07% for patients with atrial fibrillation on warfarin. Bleeding complications rates were also low.

The authors recognized a possible selection bias and the fact patients who received bridging heparin therapy were not randomized. Despite these potential flaws, there seems to be minimal risk of holding anticoagulation in the perioperative period. Bridging heparin therapy added no additional benefit.

Bottom line: There is no increased risk of thromboembolism if anticoagulation is interrupted without bridging therapy in nonvalvular atrial fibrillation patients undergoing surgery.

Are obese patients under-dosed when prescribed intravenous vancomycin?

Background: Weight-based vancomycin dosing has been recommended by the Infectious Diseases Society of America, yet flat dosing is still commonly employed. Flat dosing has the potential of increasing resistance and having adverse clinical effects.

Study design: Retrospective cohort.

Setting: Two tertiary care medical centers without pharmacy-guided vancomycin dosing programs.

Synopsis: A retrospective review was done of pharmacy prescription files at two tertiary care medical centers that did not have pharmacy-guided vancomycin programs. Patients were divided into cohorts based on their body mass index: underweight (<18.5 kg/sqm) normal weight (18.5-24.9 kg/sqm) overweight (25.0-29.9 kg/sqm) and obese (>29.9 kg/sqm). Each class was studied for rates of adequate vancomycin dosing which was defined as >10 mg/kg/dose. A total of 421 patients were included. There were no other dissimilar baseline characteristics. Total daily dose was similar for all groups with adequate initial dosing achieved in 100%, 99.0%, 93.9% and 27.7% for underweight, normal weight, overweight and obese patients, respectively.

Bottom line: Use weight-based dosing of vancomycin to limit the possibility of under-dosing in obese patients.

What is the rate of adverse events with short-term antipsychotic therapy in elderly demented patients?

Study design: Population-based retrospective cohort study.

Setting: Community-dwelling cohort and nursing home cohort.

Synopsis: A cohort of patients from Ontario age 66 and older with the diagnosis of dementia and a prescription for an anti-psychotic drug between April 1, 1997, and March 31, 2004, were divided into two groups by where they lived (community or nursing home). Each cohort was further divided into three groups based on antipsychotic exposure of none, atypical, or conventional.

All serious adverse events (defined as extra-pyramidal symptoms (EPS), cerebrovascular events, and acute care hospital admission or death) were evaluated within 30 days of initiating therapy. In the community group, individuals who received conventional antipsychotic therapy were 3.8 times more likely to have an adverse event compared with the group taking no antipsychotics. The patients prescribed an atypical antipsychotic medicine were 3.2 times more likely to experience an adverse event. In the nursing home group, patients who received conventional and atypical antipsychotic therapy were 2.4 and 1.9 times more likely to have a serious adverse event, respectively.

Bottom line: Serious events are frequent following the short-term use of antipsychotic therapy in older adults with dementia. Serious adverse events were more common among those who received a prescription for conventional rather than atypical antipsychotic drugs.

What is the association between troponin levels and adverse events in hospitalized patients with acute decompensated heart failure?

Background: There were more than 1 million hospitalizations for heart failure in 2007, making it the most costly medical condition based on diagnosis and treatment. Evidence suggests an initial risk stratification process allows for earlier implementation of aggressive therapy, which can affect hospital utilization.

Study design: Retrospective analysis of Acute Decompensated Heart Failure National Registry (ADHERE).

Setting: Hospitalization records from 274 hospitals from October 2001 to January 2004.

Synopsis: Evaluation of the data from ADHERE for outcomes associated with elevated troponin levels in patients with acute decompensated heart failure (ADHF). Patients who had a creatinine level above 2.0 mg per deciliter were excluded.

Cardiac troponin I was measured in 61,379 patients and cardiac troponin T in 7880 patients. Overall, 4,240 patients (6.2%) had an elevated troponin level. Troponin positive patients had a higher rate of in-hospital mortality than troponin negative patients (8.0% vs. 2.7%, P<0.001). The adjusted odds ratio for death among patients with a positive troponin test was 2.55. Ischemic heart failure was present in 53% of the troponin positive patients and was not a useful predictor of troponin status or mortality.

Bottom line: Measurement of troponin is an important prognostic indicator in the initial evaluation of patients with ADHF. This early assessment of risk should be factored into medical decisions with respect to triage and medical management.

Does management of ICU patients by critical care physicians reduce mortality?

Background: There is variation in the extent of involvement by critical care physicians in managing patients in ICUs. Several small studies have demonstrated improved outcomes when patients are managed by critical care physicians. This study expanded these findings by examining a national database of multiple ICUs.

Study design: Retrospective database analysis.

Setting: 123 ICUs in 100 U.S. hospitals

Synopsis: Using a national database of ICU patients, 101,832 admissions were analyzed. Controlling for ICU characteristics, patient demographics, and severity of illness (SOI), the impact of critical care management (CCM) on the primary outcome of hospital mortality was analyzed. Patients who received CCM had higher SOI, received more procedures, and had higher mortality rates than those who did not receive CCM. After adjustment for these variables, hospital mortality rates were higher for those patients who received CCM.

Because this was a retrospective analysis, it is not possible to state there was a causal relationship between care by a critical care physician and worse outcome. Other unmeasured clinical differences between the patients receiving CCM and those that did not may have existed that resulted in the higher mortality. Additionally, although the database identified management by a critical care physician, it did not differentiate whether the management was by a full-time intensivist. Therefore, conclusions cannot be made regarding the value of full-time, on-site intensivist management.

Bottom line: Additional analysis is required to determine the value of intensivists in the management of critically ill patients.

What is the frequency of iatrogenic drug overdose in patients with renal insufficiency?

Background: The Institute of Medicine Report, “To Err is Human” suggested 7,000 deaths occur annually because of medication errors. Renal insufficiency is relatively common in hospitalized patients. Previous studies have suggested overdose of medications is frequent in patients with renal insufficiency. There is a lack of large-scale studies identifying the most commonly overdosed medications and the predictive physician factors for these errors.

Study design: Retrospective observational study.

Setting: A single 1,080-bed tertiary teaching hospital

Synopsis: A clinical data mart was constructed that contained 48 months of prescription data, serum creatinine levels, along with physician characteristics. 28,954 patients with renal insufficiency had 431,119 prescription orders to analyze. 3.5% of drug doses were found excessive. The overdose rate in patients with moderate to severe renal insufficiency was 28.2%. 10 drugs accounted for 85.4% of the overdoses. There was a negative correlation between physician clinical experience and overdose rate.

Study results are limited by the study’s retrospective nature. Further, the prescribed dose was presumed to be the dose actually administered, and there were no data on the actual doses given to patients. The study was limited to a single institution and may not be generalizable.

Bottom line: Iatrogenic drug overdose is quite common among inpatients with renal insufficiency. Only a few drugs are commonly responsible. The physicians’ clinical experience, workload of prescriptions, and patients’ renal function correlated with overdose.

Will a national education program based on the “Surviving Sepsis Campaign” guidelines improve survival and processes of care?

Background: Sepsis is one of the most prevalent diseases and one of the main causes of death among hospitalized patients. Several single-center studies have suggested quality improvement efforts based on the Surviving Sepsis Guidelines were associated with better outcomes.

Study design: Prospective multicenter before-and-after study design.

Setting: 59 medical and surgical ICUs throughout Spain.

Synopsis: 854 patients with severe sepsis were enrolled in the pre–intervention group. The intervention consisted of education on the use of bundles of care. The treatment was organized into two bundles: a resuscitation bundle (six tasks to be performed within six hours) and a management bundle (four tasks to be completed within 24 hours). 1,465 patients were enrolled in the post-training period. Hospital mortality, adherence to the bundles, ICU mortality, 28-day mortality, hospital and ICU length of stay were measured.

Patients in the post-intervention group had lower mortality (44.0% vs. 39.5% P=0.04) and better compliance with the bundles improved. No other outcomes improved. One year later, mortality gains persisted but compliance with the resuscitation bundle had lapsed.

This study did not employ a control group, making it difficult to ascribe the improvement in compliance solely to the training given (some improvement in processes may have occurred independent of the training).

Study design: A randomized controlled study.

Setting: Three tertiary care hospitals in Ontario, Canada.

Synopsis: 692 patients with indwelling urinary catheters admitted to seven general medical units in three tertiary care hospitals from January 2004 to June 2006 were randomized into two groups: 269 in the stop-order group, and 252 in the usual care group. Patients in the stop-order group had fewer days of inappropriate and total urinary catheter used (2.20 days) compared with the usual care group (3.89 days). There was no difference in the incidence of urinary tract infection between both groups.

Study results were limited by several factors, including a lack of control for exposure of participants to antimicrobials, missing urine cultures, and lack of evaluation of the effect of reducing urinary catheter use on mobility and quality of life. The 1.34-day reduction in the duration of catheterization may not be sufficient to significantly reduce bacteriuria.

Bottom line: Consider using stop orders in all patients with indwelling urinary catheters.

Does interrupting anticoagulation in patients with atrial fibrillation undergoing surgery cause an increased rate of thromboembolism?

Background: There is a known risk of thromboembolism (between 0.5% and 20% annually) in patients with atrial fibrillation. Studies are limited regarding the risk of thromboembolism with holding anticoagulation in the perioperative period for nonvalvular atrial fibrillation. This study attempted to answer this question.

Study design: Prospective cohort.

Setting: Thromboembolism clinic of the Mayo Clinic.

Synopsis: 345 patients with nonvalvular atrial fibrillation whose anticoagulation was perioperatively held were monitored for three months after surgery for thromboembolic events. Warfarin therapy was held for 5.3 days +/- three days before surgery and restarted 1.3 days +/- 3.4 days after surgery. Bridging heparin therapy was used for 204/386 procedures.

Four patients suffered six thromboembolic events; two patients while receiving bridging heparin therapy and two without heparin. The total incidence of thromboembolic events was 1.1%. This is compared with an expected incidence of 0.09% to 2.07% for patients with atrial fibrillation on warfarin. Bleeding complications rates were also low.

The authors recognized a possible selection bias and the fact patients who received bridging heparin therapy were not randomized. Despite these potential flaws, there seems to be minimal risk of holding anticoagulation in the perioperative period. Bridging heparin therapy added no additional benefit.

Bottom line: There is no increased risk of thromboembolism if anticoagulation is interrupted without bridging therapy in nonvalvular atrial fibrillation patients undergoing surgery.

Are obese patients under-dosed when prescribed intravenous vancomycin?

Background: Weight-based vancomycin dosing has been recommended by the Infectious Diseases Society of America, yet flat dosing is still commonly employed. Flat dosing has the potential of increasing resistance and having adverse clinical effects.

Study design: Retrospective cohort.

Setting: Two tertiary care medical centers without pharmacy-guided vancomycin dosing programs.

Synopsis: A retrospective review was done of pharmacy prescription files at two tertiary care medical centers that did not have pharmacy-guided vancomycin programs. Patients were divided into cohorts based on their body mass index: underweight (<18.5 kg/sqm) normal weight (18.5-24.9 kg/sqm) overweight (25.0-29.9 kg/sqm) and obese (>29.9 kg/sqm). Each class was studied for rates of adequate vancomycin dosing which was defined as >10 mg/kg/dose. A total of 421 patients were included. There were no other dissimilar baseline characteristics. Total daily dose was similar for all groups with adequate initial dosing achieved in 100%, 99.0%, 93.9% and 27.7% for underweight, normal weight, overweight and obese patients, respectively.

Bottom line: Use weight-based dosing of vancomycin to limit the possibility of under-dosing in obese patients.

What is the rate of adverse events with short-term antipsychotic therapy in elderly demented patients?

Study design: Population-based retrospective cohort study.

Setting: Community-dwelling cohort and nursing home cohort.

Synopsis: A cohort of patients from Ontario age 66 and older with the diagnosis of dementia and a prescription for an anti-psychotic drug between April 1, 1997, and March 31, 2004, were divided into two groups by where they lived (community or nursing home). Each cohort was further divided into three groups based on antipsychotic exposure of none, atypical, or conventional.

All serious adverse events (defined as extra-pyramidal symptoms (EPS), cerebrovascular events, and acute care hospital admission or death) were evaluated within 30 days of initiating therapy. In the community group, individuals who received conventional antipsychotic therapy were 3.8 times more likely to have an adverse event compared with the group taking no antipsychotics. The patients prescribed an atypical antipsychotic medicine were 3.2 times more likely to experience an adverse event. In the nursing home group, patients who received conventional and atypical antipsychotic therapy were 2.4 and 1.9 times more likely to have a serious adverse event, respectively.

Bottom line: Serious events are frequent following the short-term use of antipsychotic therapy in older adults with dementia. Serious adverse events were more common among those who received a prescription for conventional rather than atypical antipsychotic drugs.

What is the association between troponin levels and adverse events in hospitalized patients with acute decompensated heart failure?

Background: There were more than 1 million hospitalizations for heart failure in 2007, making it the most costly medical condition based on diagnosis and treatment. Evidence suggests an initial risk stratification process allows for earlier implementation of aggressive therapy, which can affect hospital utilization.

Study design: Retrospective analysis of Acute Decompensated Heart Failure National Registry (ADHERE).

Setting: Hospitalization records from 274 hospitals from October 2001 to January 2004.

Synopsis: Evaluation of the data from ADHERE for outcomes associated with elevated troponin levels in patients with acute decompensated heart failure (ADHF). Patients who had a creatinine level above 2.0 mg per deciliter were excluded.

Cardiac troponin I was measured in 61,379 patients and cardiac troponin T in 7880 patients. Overall, 4,240 patients (6.2%) had an elevated troponin level. Troponin positive patients had a higher rate of in-hospital mortality than troponin negative patients (8.0% vs. 2.7%, P<0.001). The adjusted odds ratio for death among patients with a positive troponin test was 2.55. Ischemic heart failure was present in 53% of the troponin positive patients and was not a useful predictor of troponin status or mortality.

Bottom line: Measurement of troponin is an important prognostic indicator in the initial evaluation of patients with ADHF. This early assessment of risk should be factored into medical decisions with respect to triage and medical management.
