Using oral and topical cosmeceuticals to prevent and treat skin aging, Part II
This month’s column resumes my review of prevention and treatment strategies for aging skin using oral and topical cosmeceutical agents.
Preventing and treating inflammation
Skin aging can result from inflammation through several mechanisms, including the formation of reactive oxygen species. Inflammation itself arises from myriad etiologic pathways, with multiple inflammatory mediators potentially involved, including histamines, cytokines, eicosanoids (for example, prostaglandins, thromboxanes, and leukotrienes), complement cascade components, kinins, fibrinopeptide enzymes, nuclear factor–kappa B, and free radicals.
Topically applied argan oil, caffeine, chamomile, feverfew, green tea, licorice extract, aloe, linoleic acid (found in high concentrations in argan oil and safflower oil), and niacinamide are among the anti-inflammatory ingredients that have been used successfully in topical skin care to reduce inflammation. The Food and Drug Administration does not allow cosmetics to make “anti-inflammatory” claims. For this reason, these products will state they have “soothing” effects or imply they improve of redness.
Oral polypodium leucotomos has been demonstrated to suppress the effect of UV radiation on COX-2 expression.2 Also, glycolic acid has exhibited the capacity to inhibit COX-2 signaling and other inflammatory mediators.3
Preventing and treating glycation
Glycation is produced by the Maillard reaction, a chemical reaction – particularly well known in cooking – between an amino acid and a sugar molecule that typically requires heat. This reaction was first described by Louis Camille Maillard in 1912 when he noted that amino acids can react with sugar to yield brown or golden-brown substances. It took until the 1980s for scientists to understand the importance of glycation in health.
When glycation occurs, sugar molecules attach to proteins, creating cross-linked proteins known as advanced glycation end products (or AGEs) and causing a series of chemical reactions. Glycation occurs in collagen fibers and results in the formation of cross-links that bind collagen fibers to each other, which leaves the skin stiffer. Glycosylated collagen is believed to be a factor in the appearance of aged skin.4 Glycation also can affect elastin: Recent research suggests that glycation can engender elastosis, which is elastin that is abnormally clumped together and presents more frequently in aged skin.
Several antiaging skin care products claim to treat glycation, but – unfortunately – glycation is not a reversible reaction. It must be prevented in the first place. Some studies suggest that antioxidants can prevent glycation, but it is more likely that they just divert the process down a different pathway that still leads to glycation. Reducing serum glucose levels is the optimum method of preventing glycation.5 Dietary intervention and oral metformin are recommended for lowering glycation.
REVERSING SKIN CELL AGING
Epidermal keratinocytes in aging
Young basal stem cells synthesize a plethora of new keratinocytes at a pace that leads to fast cell turnover and vigorous production of protective epidermal constituents. Old keratinocytes display less energy, show reduced responsiveness to cellular signals, and do not synthesize these protective components.6,7 Keratinocyte stem cell function declines over time while damage accumulates, as seen in a diminished response to growth factors, decreased keratinization, and impaired function.8
Dermal fibroblasts in cutaneous aging
Young fibroblasts produce key cellular constituents, including collagen, elastin, hyaluronic acid, and heparan sulfate. This production declines in older fibroblasts. Like aging keratinocytes, old fibroblasts lose energy and responsiveness to growth factors and other cellular signals.6,7
Rejuvenating aged skin with cosmeceuticals
Gene expression, growth factors, cytokines, chemokines, and receptor activation guide the function of keratinocytes and fibroblasts. To reverse or slow cellular skin aging, old keratinocytes and fibroblasts must be galvanized to respond to such signals or the signals must be enhanced.
Stimulating old keratinocytes and fibroblasts
Essential steps in stimulating aged keratinocytes and fibroblasts include: activating gene expression, adding growth factors, activating cytokines and chemokines, turning on receptors, and making cells more responsive to signals.
Influencing gene expression
Retinoids are known to affect collagen genes and increase activity of procollagen genes, thereby reducing the production of collagenase. Many studies have shown the efficacy of retinoids in treating aged skin and preventing cutaneous aging in both areas frequently exposed to the sun but also those that aren’t.9,10 Prescription retinoids (tretinoin, adapalene, tazarotene) and over-the-counter retinoids (retinol) are first-line options to treat and prevent aging by stimulating old keratinocytes and fibroblasts.10,11 However, exposing retinoic acid receptors to retinoids almost invariably leads to erythema and flaking in the first few weeks. Therefore, retinoids should be titrated slowly. Note that retinoid esters, such as retinyl palmitate and retinyl linoleate, do not penetrate well into the dermis;12 they also are not as effective as retinol, tretinoin, adapalene, and tazarotene. Compliance with retinoids is always an issue with patients. They should receive printed educational material about how to begin use and why it is important to use these products consistently.
Growth factors
The use of cosmetic formulations that contain growth factors can contribute to skin rejuvenation. There are various types of growth factors that have the capacity to stimulate old keratinocytes and fibroblasts to enhance function.17 Growth factors, which are inactive or vulnerable to degradation in their native, soluble form, can directly energize genes or act as a signaling mechanism. To exert their quintessential functions, growth factors must be transferred to the correct receptor site in order for the cell to respond to their signal.18
Heparan sulfate
Heparan sulfate (HS) plays a primary role in cell-to-cell communications. It increases cellular response to growth factors by facilitating the response of old, lazy fibroblasts to the cellular signals.18 HS binds, stores, and protects growth factors, which allows them to complete movement to their targets, and then presents them to the appropriate binding site.18,19 A topically applied analogue of HS has been demonstrated to rejuvenate aged skin.20
Stem cells
Stem cells included and pointedly marketed in cosmeceutical products are usually plant derived, are too large to penetrate the stratum corneum, display short shelf lives, and do not behave as human stem cells would. As a result, stem cells in cosmeceutical agents are essentially useless.
However, novel technologies have revealed ingredients that can incite native stem cells to repopulate the epidermis and dermis with young cells. Stem cells in skin include basal stem cells and 10 varieties of hair follicle stem cells. The LGR6+ hair follicle cells play a pivotal role in repopulating the epidermis after wounding has occurred.21,22 Aesthetic physicians have known for several years that inducing skin wounding with lasers, needles, and acidic peels leads to improvement in its appearance. Researchers have provided new data showing that wounding the skin prompts LGR6+ stem cells to repopulate the epidermis. Once wounding occurs, neutrophils release the peptide defensin, which stimulates the LGR6+ stem cells to repopulate the epidermis.23 Topical defensin that has been formulated to penetrate into hair follicles, where the LGR6+ stem cells reside, has been demonstrated to render a smoother, more youthful appearance to the skin.
Conclusion
It is important for practitioners to identify patients at risk for premature skin aging as early as possible and start them on an appropriate and consistent skin care regimen. This typically will include at least a daily sunscreen with an SPF 15 or higher, a nightly topical retinoid, and oral and topical antioxidants. The patient’s additional skin type proclivities (for example, dryness, inflammation, melanocyte activity) should guide the physician as to how to combine these baseline product types with cleansers, moisturizers, and formulations with hydroxy acids, growth factors, heparan sulfate, and defensin.
Several studies have revealed that patients exhibit poor compliance with recommended regimens.24 Informing patients about the need for skin protection and providing printed instructions can help to improve compliance.25 This can promote healthy lifestyle habits and compliance with scientifically proven antiaging therapies.

Antipsychotics for OCD: What the guidelines recommend
The 2013 American Psychiatric Association (APA) obsessive-compulsive disorder (OCD) treatment guidelines include recommendations regarding the use of antipsychotics in patients who do not respond to first-line treatment with selective serotonin reuptake inhibitors (SSRIs) and/or cognitive-behavioral therapy (CBT). The APA recommends evaluating contributing factors, including comorbidities, family support, and ability to tolerate psychotherapy or maximum recommended drug doses, before augmenting or switching therapies.1
In patients with a partial response to SSRIs and/or CBT, the APA suggests that augmentation may be preferable to switching treatments. Augmentation strategies for SSRIs include antipsychotics or CBT with Exposure Response Prevention (ERP); augmentation strategies for CBT include SSRIs. Combining SSRIs and CBT may decrease the chance of relapse when medication is discontinued. If the patient has a partial response to ERP, intensification of therapy also can be considered based on patient-specific factors. In non-responders, switching therapies may be necessary. Alternative treatments including a different SSRI; an antidepressant from a difference class, such as clomipramine or mirtazapine; an antipsychotic; or CBT.
The 2006 National Institute for Health and Clinical Excellence guidelines for OCD recommend additional high-intensity CBT, adding an antipsychotic to an SSRI or clomipramine, or combining clomipramine with citalopram in non-responders. There is no guidance regarding the order in which these treatments should be trialed. Antipsychotics are recommended as an entire class, and there are no recommendations regarding dosing or long-term risks. These guidelines are based on limited evidence, including only 1 trial of quetiapine and 1 trial of olanzapine.2,3
Efficacy
The 2013 National Institute for Health Care and Excellence Evidence Update included a 2010 Cochrane Review of 11 randomized controlled trials (RCTs) of antipsychotics as adjunctive treatment to SSRIs.5 All trials were <6 months, and most were limited regarding quality aspects. Two trials found no statistically significant difference with olanzapine in efficacy measures (Y-BOCS mean difference [MD] −2.96; 95% confidence interval [CI] −7.41 to 1.22; effect size d = −2.96 [−7.14, 1.22]). Among patients with no clinically significant change (defined as ≤35% reduction in Y-BOCS), there was no significant difference between groups (n = 44, 1 RCT, odds ratio [OR] 0.76; 95% CI 0.17 to 3.29; effect size d = 0.76 [0.17, 3.29]). Studies found increased weight gain with olanzapine compared with antidepressant monotherapy.
Statistically significant differences were demonstrated with the addition of quetiapine to antidepressant monotherapy as shown in Y-BOCS score at endpoint (Y-BOCS MD −2.28; 95% CI −4.05 to −0.52; effect size d −2.28 [−4.05, −0.52]). Quetiapine also demonstrated benefit for depressive and anxiety symptoms. Among patients with no clinically significant change (defined as ≤35% reduction in Y-BOCS), there was a significant difference between groups (n = 80, 2 RCTs, OR 0.27; 95% CI 0.09 to 0.87; effect size d = 0.27 [0.09, 0.87]).
Adjunctive treatment with risperidone was superior to antidepressant monotherapy for participants without a significant response in OCD symptom severity of at least 25% with validated measures (OR 0.17; 95% CI 0.04 to 0.66; effect size d = 0.17 [0.04, 0.66]), and in depressive and anxiety symptoms. Mean reduction in Y-BOCS scores was not statistically significant with risperidone (MD −3.35; 95% CI −8.25 to 1.55; effect size d = −3.35 [−8.25, 1.55]).5
A 2014 meta-analysis by Veale et al3 included double-blind, randomized trials that examined atypical antipsychotics compared with placebo for adults with OCD that used an intention-to-treat analysis. Unlike the Cochrane Review, these studies used the Y-BOCS as a primary outcome measure. Participants had a Y-BOCS score of ≥16; had at least 1 appropriate trial of an SSRI or clomipramine (defined as the maximum dose tolerated for at least 8 weeks); and had to continue taking the SSRI or
Fourteen articles were included in the meta-analysis, but all had small sample sizes and no long-term follow-up data.3 Antipsychotics in the meta-analysis included risperidone (4 studies), quetiapine (5 studies), olanzapine (2 studies),
The overall difference in Y-BOCS score change between drug and placebo groups was 2.34 points, which had an overall effect size of d = 0.40. Those taking antipsychotics had approximately a 10% reduction in Y-BOCS score over time. The overall difference was statistically significant with risperidone (overall mean reduction of 3.89 points on the Y-BOCS; 95% CI 1.43 to 5.48; effect size of d = 0.53) and aripiprazole (difference in Y-BOCS outcome 0.1 scores of 6.29 points; effect size of d = 1.11). One trial of risperidone used a low dose (0.5 mg) and had a larger effect size than the studies that used moderate doses. The overall difference was not statistically significant for quetiapine (difference of Y-BOCS outcome scores of 0.81 points) or olanzapine (difference in Y-BOCS outcome scores of −0.19; indicating <1 point difference on the Y-BOCS).3
Studies included in the meta-analysis ranged in durations from 6 to 16 weeks; duration of ≥4 weeks did not make a difference in response. One study demonstrated a worsening of symptoms in the quetiapine group between weeks 4 and 12. Only 4 studies included most patients that had a previous trial of CBT. One study with an additional treatment arm evaluating CBT found that adding CBT was superior to adjunctive risperidone or placebo. Another study found that adding clomipramine or placebo to
Two studies included in the meta-analysis classified OCD symptoms by subtype, such as by dimensions of checking; symmetry, ordering, counting, and repeating; contamination and cleaning; and hoarding. Currently, no clinically significant predictor of outcome of antipsychotic therapy has been identified. Two studies included in the meta-analysis assessed patients with comorbid tic disorders and found no difference by treatment. One study demonstrated benefit of haloperidol in patients with comorbid tic disorders compared with those without comorbid tic disorders. Of note, none of the studies included in the meta-analysis excluded patients with hoarding characteristics, which generally indicate a worse prognosis with treatment.3
In 2015, Dold et al6 provided an update to a 2013 meta-analysis7 assessing antipsychotic augmentation of SSRIs in treatment-resistant OCD. This update included 2 new RCTs. The 2013 analysis7 concluded that risperidone should be considered first-line and is preferred over olanzapine and quetiapine. However, the update found the highest effect size for aripiprazole (d = −1.35), followed by haloperidol (d = −0.82), risperidone (d = −0.59), quetiapine (d = −0.50), olanzapine (d = −0.49), and paliperidone (d = −0.21).6,7
The 2015 update6 concluded that the antipsychotic doses used in trials were moderate and that there was no association between dose and treatment response, indicating that high doses of antipsychotics may not be more effective. Dold et al6 postulated that the antipsychotic doses required for treating OCD are similar to those used in treating major depressive disorder and lower than doses used in treating schizophrenia. The 2013 meta-analysis demonstrated that moderate doses of antipsychotics resulted in statistically significant efficacy (relative risk [RR] = 3.99, 95% CI 1.92 to 8.27), while low doses did not demonstrate statistical significance (RR = 1.06, 95% CI 0.45 to 2.53).6,7
The 2015 subgroup analysis update evaluated the duration of SSRI treatment prior to the antipsychotic augmentation phase, but did not demonstrate statistically significant efficacy for studies with <8 weeks’ duration of SSRI treatment, further highlighting the need for extended duration of treatment with an SSRI prior to augmentation.6
The 2013 meta-analysis discussed populations with comorbid tic disorders, including a study that found that patients with OCD and comorbid tic disorders benefit more from adjunctive antipsychotic therapy than those without the comorbidity. The 2015 update excluded trials that included patients with comorbid tic disorders to reduce bias, which did not affect the overall effect sizes of the data.6,7
In summary, efficacy has been demonstrated for risperidone and aripiprazole. There has been no benefit demonstrated with olanzapine and limited benefit with quetiapine. One study suggested worsening of symptoms with quetiapine the longer that treatment persisted.3,5-7
Safety
Assessing potential harms related to the use of antipsychotics in treating OCD is complicated, because this information is not always assessed in trials. Instead, researchers often focus on exploring potential benefits because long-term effects of antipsychotics, including sedation, weight gain, metabolic syndrome, and extrapyramidal side effects, are well documented.3
Trials included in the meta-analysis by Veale et al3 had a maximum duration of 16 weeks, so it is likely that many of the potential harms of antipsychotic use would not yet have been measurable. The authors cautioned that, although aripiprazole and risperidone demonstrated benefit, their benefit must be weighed against the potential physical risks of long-term antipsychotic use.3One study that was not included in the meta-analysis by Veale et al3 evaluated individuals who did not respond to a SSRI, and randomly assigned them to quetiapine, olanzapine, or risperidone plus CBT. At 1-year follow-up, 50% of participants receiving an antipsychotic had an increase of >10% in body mass index (BMI) and had higher fasting blood sugars compared with only 15.2% of participants with increased BMI in the comparison group (SSRI responders).3
Foa et al8 investigated long-term outcomes (ie, 6 months) of SSRI augmentation with ERP or risperidone in patients with OCD. Forty patients were randomized to receive risperidone, and 9 were considered responders. Only 8 chose to enter the maintenance phase, and of those participants, 5 did not complete the study. Two withdrew due to worsening depression, 2 withdrew due to intolerable adverse effects, and 1 was lost to follow-up. Unfortunately, there was no further discussion of what the intolerable adverse effects were.8
Patients with comorbid schizophrenia and OCD face additional risks. Lifetime prevalence rates of OCD are greater in persons with schizophrenia compared with the general population (26% vs 8%, respectively). Most studies have demonstrated poor prognosis and medication adherence among patients with comorbid schizophrenia and OCD. Fonseka et al9 assessed the risk of antipsychotic induction and exacerbation of OCD symptoms in patients with schizophrenia. Induction and exacerbation of OCD symptoms
Evidence of olanzapine induction and exacerbation of OCD symptoms is also limited to case reports and retrospective studies. However, some studies have estimated induction of OCD symptoms with olanzapine in 11% to 20% of patients.9 There is insufficient evidence to form conclusions regarding other antipsychotics. Fonseka et al9 recommends switching to an antipsychotic with lower 5HT-2 binding affinity or adding an SSRI, such as fluvoxamine, if induction or exacerbation of OCD symptoms occurs.
Consider long-term risks
The evidence for benefits with antipsychotics in treatment-resistant OCD is limited by different populations recruited, small sample sizes, and lack of long-term follow-up. Most evidence supports using ERP over antipsychotics for treating OCD symptoms that have not responded to SSRIs. However, ERP poses its own challenges that may limit clinical utility, such as economic and time restraints. Therefore, benefits with antipsychotics, such as risperidone and aripiprazole, must be weighed against potential long-term risks of treatment, including sedation, weight gain, metabolic syndrome, and extrapyramidal side effects.
Regarding Mr. E’s case, because he had been maximized on SSRI therapy for an adequate duration (escitalopram, 40 mg/d, for 12 weeks) and completed CBT with ERP with a partial response, adding risperidone, 0.5 mg at bedtime, was an appropriate treatment option that is supported by the available guidelines and evidence. The risperidone dose is reflective of the initial dosing strategies used in clinical trials. It is recommended to assess efficacy of treatment at 8 weeks with a validated measure, such as the Y-BOCS. A dose increase may be needed to achieve clinically significant symptom improvement, because moderate doses of risperidone have demonstrated efficacy in trials; however, high doses of risperidone are unlikely to provide additional benefit and increase the risk of adverse effects. If risperidone does not provide a clinically favorable risk–benefit ratio for Mr. E, aripiprazole is a potential alternative.

There is no guidance regarding the order in which these treatments should be trialed.

These guidelines are based on limited evidence, including only 1 trial of quetiapine and 1 trial of olanzapine.2,3
Efficacy
The 2013 National Institute for Health Care and Excellence Evidence Update included a 2010 Cochrane Review of 11 randomized controlled trials (RCTs) of antipsychotics as adjunctive treatment to SSRIs.5 All trials were <6 months, and most were limited regarding quality aspects. Two trials found no statistically significant difference with olanzapine in efficacy measures (Y-BOCS mean difference [MD] −2.96; 95% confidence interval [CI] −7.41 to 1.22; effect size d = −2.96 [−7.14, 1.22]). Among patients with no clinically significant change (defined as ≤35% reduction in Y-BOCS), there was no significant difference between groups (n = 44, 1 RCT, odds ratio [OR] 0.76; 95% CI 0.17 to 3.29; effect size d = 0.76 [0.17, 3.29]). Studies found increased weight gain with olanzapine compared with antidepressant monotherapy.
Statistically significant differences were demonstrated with the addition of quetiapine to antidepressant monotherapy as shown in Y-BOCS score at endpoint (Y-BOCS MD −2.28; 95% CI −4.05 to −0.52; effect size d −2.28 [−4.05, −0.52]). Quetiapine also demonstrated benefit for depressive and anxiety symptoms. Among patients with no clinically significant change (defined as ≤35% reduction in Y-BOCS), there was a significant difference between groups (n = 80, 2 RCTs, OR 0.27; 95% CI 0.09 to 0.87; effect size d = 0.27 [0.09, 0.87]).
Adjunctive treatment with risperidone was superior to antidepressant monotherapy for participants without a significant response in OCD symptom severity of at least 25% with validated measures (OR 0.17; 95% CI 0.04 to 0.66; effect size d = 0.17 [0.04, 0.66]), and in depressive and anxiety symptoms. Mean reduction in Y-BOCS scores was not statistically significant with risperidone (MD −3.35; 95% CI −8.25 to 1.55; effect size d = −3.35 [−8.25, 1.55]).5
A 2014 meta-analysis by Veale et al3 included double-blind, randomized trials that examined atypical antipsychotics compared with placebo for adults with OCD that used an intention-to-treat analysis. Unlike the Cochrane Review, these studies used the Y-BOCS as a primary outcome measure. Participants had a Y-BOCS score of ≥16; had at least 1 appropriate trial of an SSRI or clomipramine (defined as the maximum dose tolerated for at least 8 weeks); and had to continue taking the SSRI or
Fourteen articles were included in the meta-analysis, but all had small sample sizes and no long-term follow-up data.3 Antipsychotics in the meta-analysis included risperidone (4 studies), quetiapine (5 studies), olanzapine (2 studies),
The overall difference in Y-BOCS score change between drug and placebo groups was 2.34 points, which had an overall effect size of d = 0.40. Those taking antipsychotics had approximately a 10% reduction in Y-BOCS score over time. The overall difference was statistically significant with risperidone (overall mean reduction of 3.89 points on the Y-BOCS; 95% CI 1.43 to 5.48; effect size of d = 0.53) and aripiprazole (difference in Y-BOCS outcome 0.1 scores of 6.29 points; effect size of d = 1.11). One trial of risperidone used a low dose (0.5 mg) and had a larger effect size than the studies that used moderate doses. The overall difference was not statistically significant for quetiapine (difference of Y-BOCS outcome scores of 0.81 points) or olanzapine (difference in Y-BOCS outcome scores of −0.19; indicating <1 point difference on the Y-BOCS).3
Studies included in the meta-analysis ranged in durations from 6 to 16 weeks; duration of ≥4 weeks did not make a difference in response. One study demonstrated a worsening of symptoms in the quetiapine group between weeks 4 and 12. Only 4 studies included most patients that had a previous trial of CBT. One study with an additional treatment arm evaluating CBT found that adding CBT was superior to adjunctive risperidone or placebo. Another study found that adding clomipramine or placebo to
Two studies included in the meta-analysis classified OCD symptoms by subtype, such as by dimensions of checking; symmetry, ordering, counting, and repeating; contamination and cleaning; and hoarding. Currently, no clinically significant predictor of outcome of antipsychotic therapy has been identified. Two studies included in the meta-analysis assessed patients with comorbid tic disorders and found no difference by treatment. One study demonstrated benefit of haloperidol in patients with comorbid tic disorders compared with those without comorbid tic disorders. Of note, none of the studies included in the meta-analysis excluded patients with hoarding characteristics, which generally indicate a worse prognosis with treatment.3
In 2015, Dold et al6 provided an update to a 2013 meta-analysis7 assessing antipsychotic augmentation of SSRIs in treatment-resistant OCD. This update included 2 new RCTs. The 2013 analysis7 concluded that risperidone should be considered first-line and is preferred over olanzapine and quetiapine. However, the update found the highest effect size for aripiprazole (d = −1.35), followed by haloperidol (d = −0.82), risperidone (d = −0.59), quetiapine (d = −0.50), olanzapine (d = −0.49), and paliperidone (d = −0.21).6,7
The 2015 update6 concluded that the antipsychotic doses used in trials were moderate and that there was no association between dose and treatment response, indicating that high doses of antipsychotics may not be more effective. Dold et al6 postulated that the antipsychotic doses required for treating OCD are similar to those used in treating major depressive disorder and lower than doses used in treating schizophrenia. The 2013 meta-analysis demonstrated that moderate doses of antipsychotics resulted in statistically significant efficacy (relative risk [RR] = 3.99, 95% CI 1.92 to 8.27), while low doses did not demonstrate statistical significance (RR = 1.06, 95% CI 0.45 to 2.53).6,7
The 2015 subgroup analysis update evaluated the duration of SSRI treatment prior to the antipsychotic augmentation phase, but did not demonstrate statistically significant efficacy for studies with <8 weeks’ duration of SSRI treatment, further highlighting the need for extended duration of treatment with an SSRI prior to augmentation.6
The 2013 meta-analysis discussed populations with comorbid tic disorders, including a study that found that patients with OCD and comorbid tic disorders benefit more from adjunctive antipsychotic therapy than those without the comorbidity. The 2015 update excluded trials that included patients with comorbid tic disorders to reduce bias, which did not affect the overall effect sizes of the data.6,7
In summary, efficacy has been demonstrated for risperidone and aripiprazole. There has been no benefit demonstrated with olanzapine and limited benefit with quetiapine. One study suggested worsening of symptoms with quetiapine the longer that treatment persisted.3,5-7
Safety
Assessing potential harms related to the use of antipsychotics in treating OCD is complicated, because this information is not always assessed in trials. Instead, researchers often focus on exploring potential benefits because long-term effects of antipsychotics, including sedation, weight gain, metabolic syndrome, and extrapyramidal side effects, are well documented.3
Trials included in the meta-analysis by Veale et al3 had a maximum duration of 16 weeks, so it is likely that many of the potential harms of antipsychotic use would not yet have been measurable. The authors cautioned that, although aripiprazole and risperidone demonstrated benefit, their benefit must be weighed against the potential physical risks of long-term antipsychotic use.3One study that was not included in the meta-analysis by Veale et al3 evaluated individuals who did not respond to a SSRI, and randomly assigned them to quetiapine, olanzapine, or risperidone plus CBT. At 1-year follow-up, 50% of participants receiving an antipsychotic had an increase of >10% in body mass index (BMI) and had higher fasting blood sugars compared with only 15.2% of participants with increased BMI in the comparison group (SSRI responders).3
Foa et al8 investigated long-term outcomes (ie, 6 months) of SSRI augmentation with ERP or risperidone in patients with OCD. Forty patients were randomized to receive risperidone, and 9 were considered responders. Only 8 chose to enter the maintenance phase, and of those participants, 5 did not complete the study. Two withdrew due to worsening depression, 2 withdrew due to intolerable adverse effects, and 1 was lost to follow-up. Unfortunately, there was no further discussion of what the intolerable adverse effects were.8
Patients with comorbid schizophrenia and OCD face additional risks. Lifetime prevalence rates of OCD are greater in persons with schizophrenia compared with the general population (26% vs 8%, respectively). Most studies have demonstrated poor prognosis and medication adherence among patients with comorbid schizophrenia and OCD. Fonseka et al9 assessed the risk of antipsychotic induction and exacerbation of OCD symptoms in patients with schizophrenia. Induction and exacerbation of OCD symptoms
Evidence of olanzapine induction and exacerbation of OCD symptoms is also limited to case reports and retrospective studies. However, some studies have estimated induction of OCD symptoms with olanzapine in 11% to 20% of patients.9 There is insufficient evidence to form conclusions regarding other antipsychotics. Fonseka et al9 recommends switching to an antipsychotic with lower 5HT-2 binding affinity or adding an SSRI, such as fluvoxamine, if induction or exacerbation of OCD symptoms occurs.
Consider long-term risks
The evidence for benefits with antipsychotics in treatment-resistant OCD is limited by different populations recruited, small sample sizes, and lack of long-term follow-up. Most evidence supports using ERP over antipsychotics for treating OCD symptoms that have not responded to SSRIs. However, ERP poses its own challenges that may limit clinical utility, such as economic and time restraints. Therefore, benefits with antipsychotics, such as risperidone and aripiprazole, must be weighed against potential long-term risks of treatment, including sedation, weight gain, metabolic syndrome, and extrapyramidal side effects.
Regarding Mr. E’s case, because he had been maximized on SSRI therapy for an adequate duration (escitalopram, 40 mg/d, for 12 weeks) and completed CBT with ERP with a partial response, adding risperidone, 0.5 mg at bedtime, was an appropriate treatment option that is supported by the available guidelines and evidence. The risperidone dose is reflective of the initial dosing strategies used in clinical trials. It is recommended to assess efficacy of treatment at 8 weeks with a validated measure, such as the Y-BOCS. A dose increase may be needed to achieve clinically significant symptom improvement, because moderate doses of risperidone have demonstrated efficacy in trials; however, high doses of risperidone are unlikely to provide additional benefit and increase the risk of adverse effects. If risperidone does not provide a clinically favorable risk–benefit ratio for Mr. E, aripiprazole is a potential alternative.

Welcome to The New Gastroenterologist online!
Dear Colleagues,
It is with great excitement that I introduce the first e-newsletter version of The New Gastroenterologist! As more content in medicine, and life in general, is moving toward digital platforms, we at the AGA believe this transition will improve both content dissemination and accessibility to all our readers. In this new format, we will continue to provide articles on topics of importance to the early-career community, expand our offerings by including the new “In Focus” articles (concise overviews of GI topics) both digitally and in GI & Hepatology News print issues, as well as increase the use of multimedia resources, such as videos, to further enhance our content.
In this issue of The New Gastroenterologist, our In Focus article provides a practical overview of the management of chronic constipation. This article, written by Nitin Ahuja and James Reynolds from the Neurogastroenterology and Motility Program at the University of Pennsylvania, Philadelphia, addresses a common topic in our field, and can also be found in the February print issue of GI & Hepatology News. To complement this article, there is a corresponding video abstract that can be viewed.
Also in this issue, Richard Peek (Vanderbilt University, Nashville, Tenn.) – one of the Coeditors in Chief of Gastroenterology – provides a summary of the newly created 1-year editorial fellowship for the AGA’s flagship journal. This is a fantastic new opportunity and you can learn firsthand about the experience of the inaugural editorial fellow, Eric Shah (University of Michigan, Ann Arbor), in an accompanying video. Additionally, as helping patients make a successful transition from a pediatric GI practice to an adult GI practice can be very challenging, in this issue Manreet Kaur and Allyson Wyatt (Baylor College of Medicine, Houston) provide a primer on how to successfully aid in this transition.
Are you considering a career in hospital administration? If so, you will enjoy reading about pursuing a career in hospital administration from Brijen Shah, who is the chief medical officer of Mount Sinai Queens (Icahn School of Medicine at Mount Sinai, New York). Have you been to one of the AGA’s Regional Practice Skills Workshops? These workshops are sponsored by the AGA Trainee and Early Career Committee and held in a growing number of cities across the country. In this issue, Munish Ashat (University of Iowa, Iowa City) provides a recap of the workshop he attended, complete with many useful career pearls.
I hope that you also enjoy the other features in the new e-newsletter format of The New Gastroenterologist. I especially want to point out one of our new sections entitled “In Case You Missed It.” As we all undoubtedly experience information overload with so many new articles released each month, this section collects relevant articles from the numerous AGA publications and consolidates them to ensure you don’t miss any of this great content.
If you are interested in contributing to future issues of The New Gastroenterologist or if there are topics that would interest you, please let us know. You can contact me (bryson.katona@uphs.upenn.edu) or the managing editor of The New Gastroenterologist, Ryan Farrell (rfarrell@gastro.org).

Study eyed natural history of branch-duct intraductal papillary mucinous neoplasms
Branch-duct intraductal papillary mucinous neoplasms (BD-IPMNs) grew at a median annual rate of 0.8 mm in a retrospective study of 1,369 patients.
While most of these cysts were “indolent and dormant,” some grew rapidly and developed “other worrisome features,” Youngmin Han, MS, of Seoul (South Korea) National University reported with his associates in the February issue of Gastroenterology. Therefore, clinicians should plan follow-up surveillance based on initial cyst size and growth rate, they concluded.
Based on their findings, the researchers recommended surgery for young, fit, asymptomatic patients who have BD-IPMNs with a diameter of least 30 mm or with thickened cyst walls or those who have a main pancreatic duct measuring 5-9 mm. Surgery also should be considered when patients have lymphadenopathy, high tumor marker levels, or an abrupt change in pancreatic duct caliber with distal pancreatic atrophy or a rapidly growing cyst, they said.
For asymptomatic patients whose cysts are under 10 mm and who do not have worrisome features, they recommended follow-up with CT or MRI at 6 months and then every 2 years after that. Cysts of 10-20 mm should be imaged at 6 months, at 12 months, and then every 1.5-2 years after that, they said. Patients with cyst diameters greater than 20 mm “should undergo MRI or CT or EUS [endoscopic ultrasound] every 6 months for 1 year and then annually thereafter, until the cyst size and features become stable,” they added. Patients whose cysts have a diameter of 30 mm or greater “should be closely monitored with MRI or CT or EUS every 6 months. Surgical resection can be considered in younger patients or those with other combined worrisome features.”
To characterize the natural history of BD-IPMN, the investigators evaluated clinical and imaging data collected between 2001 and 2016 from patients with classical features of BD-IPMN. Each patient included in the study provided 3 or more years of CT, MRI, EUS, and endoscopic retrograde cholangiopancreatography data. The researchers used regression models to estimate changes in sizes of cysts and main pancreatic ducts.
Median follow-up time was 61 months (range, 36-189 months). Cyst diameter averaged 12.8 mm (standard deviation, 6.5 mm) at baseline and 17 mm (SD, 9.2 mm) at final measurement. Larger baseline diameter was associated with faster growth (P = .046): Cysts measuring less than 10 mm at baseline grew at a median annual rate of 0.8 mm (SD, 1.1 mm), while those measuring at least 30 mm grew at a median annual rate of 1.2 mm (SD, 2.1 mm).
Worrisome features were present in 59 patients at baseline and emerged in another 150 patients during follow-up. At baseline, only 2.3% of cysts exceeded 30 mm in diameter, but 8.0% did at final measurement. Cyst wall thickening was found in 0.5% of patients at baseline and 3.7% of patients at final measurement. Main pancreatic ducts measured 5-9 mm in 1.9% of patients at baseline and in 5.6% of patients at final measurement. Additionally, the prevalence of mural nodules rose from 0.4% at baseline to 3.1% at final measurement.
Main pancreatic ducts averaged 1.8 mm (SD, 1.0 mm) at baseline and 2.4 mm (SD, 1.8 mm) at final measurement. Compared with the values seen with smaller cysts, larger baseline cyst diameter correlated significantly with larger main pancreatic ducts, more cases of cyst wall thickening, and more cases with mural nodules (P less than .001 for all comparisons).
The study was funded by a grant from Korean Health Technology R&D Project of Ministry of Health and Welfare, Republic of Korea. The investigators reported having no conflicts of interest.

The appropriate management of branch-duct intraductal papillary mucinous neoplasms (BD-IPMNs), a precursor cystic lesion to pancreatic cancer, has been a controversial issue since their initial description in 1982. Current national and international guidelines are primarily based on surgical series with potential selection bias and on observational studies with short surveillance periods. Consequently, there is limited information on the natural history and, more importantly, the malignant potential of BD-IPMNs.
The study by Youngmin Han and colleagues represents a comprehensive analysis of over 1,000 patients, each with at least 3 years of follow-up for a suspected BD-IPMN. In addition, the authors identified an optimal screening method for patients based on cyst size. Their data largely validates prior reports and will undoubtedly serve as the basis for future pancreatic cyst guidelines.
However, as the authors note, limitations of their study include its retrospective design and validation of their screening protocol. Moreover, several lingering questions remain for patients with BD-IPMNs: What is the best method of measuring a BD-IPMN (for example, CT, MRI, or endoscopic ultrasound)? How long should surveillance continue? And what is the role for cytopathology and ancillary studies, such as carcinoembryonic antigen testing, molecular testing, and testing for other pancreatic cyst biomarkers? At the risk of enouncing a cliché, “further studies are needed” to identify an optimal treatment algorithm and, considering the increasingly frequent detection of pancreatic cysts, a cost-effective approach to the evaluation of patients with BD-IPMNs.

For asymptomatic patients whose cysts are under 10 mm and who do not have worrisome features, they recommended follow-up with CT or MRI at 6 months and then every 2 years after that. Cysts of 10-20 mm should be imaged at 6 months, at 12 months, and then every 1.5-2 years after that, they said. Patients with cyst diameters greater than 20 mm “should undergo MRI or CT or EUS [endoscopic ultrasound] every 6 months for 1 year and then annually thereafter, until the cyst size and features become stable,” they added. Patients whose cysts have a diameter of 30 mm or greater “should be closely monitored with MRI or CT or EUS every 6 months. Surgical resection can be considered in younger patients or those with other combined worrisome features.”
To characterize the natural history of BD-IPMN, the investigators evaluated clinical and imaging data collected between 2001 and 2016 from patients with classical features of BD-IPMN. Each patient included in the study provided 3 or more years of CT, MRI, EUS, and endoscopic retrograde cholangiopancreatography data. The researchers used regression models to estimate changes in sizes of cysts and main pancreatic ducts.
Median follow-up time was 61 months (range, 36-189 months). Cyst diameter averaged 12.8 mm (standard deviation, 6.5 mm) at baseline and 17 mm (SD, 9.2 mm) at final measurement. Larger baseline diameter was associated with faster growth (P = .046): Cysts measuring less than 10 mm at baseline grew at a median annual rate of 0.8 mm (SD, 1.1 mm), while those measuring at least 30 mm grew at a median annual rate of 1.2 mm (SD, 2.1 mm).
Worrisome features were present in 59 patients at baseline and emerged in another 150 patients during follow-up. At baseline, only 2.3% of cysts exceeded 30 mm in diameter, but 8.0% did at final measurement. Cyst wall thickening was found in 0.5% of patients at baseline and 3.7% of patients at final measurement. Main pancreatic ducts measured 5-9 mm in 1.9% of patients at baseline and in 5.6% of patients at final measurement. Additionally, the prevalence of mural nodules rose from 0.4% at baseline to 3.1% at final measurement.
Main pancreatic ducts averaged 1.8 mm (SD, 1.0 mm) at baseline and 2.4 mm (SD, 1.8 mm) at final measurement. Compared with the values seen with smaller cysts, larger baseline cyst diameter correlated significantly with larger main pancreatic ducts, more cases of cyst wall thickening, and more cases with mural nodules (P less than .001 for all comparisons).
The study was funded by a grant from Korean Health Technology R&D Project of Ministry of Health and Welfare, Republic of Korea. The investigators reported having no conflicts of interest.

Branch-duct intraductal papillary mucinous neoplasms (BD-IPMNs) grew at a median annual rate of 0.8 mm in a retrospective study of 1,369 patients.
While most of these cysts were “indolent and dormant,” some grew rapidly and developed “other worrisome features,” Youngmin Han, MS, of Seoul (South Korea) National University reported with his associates in the February issue of Gastroenterology. Therefore, clinicians should plan follow-up surveillance based on initial cyst size and growth rate, they concluded.
Based on their findings, the researchers recommended surgery for young, fit, asymptomatic patients who have BD-IPMNs with a diameter of least 30 mm or with thickened cyst walls or those who have a main pancreatic duct measuring 5-9 mm.

One in five Crohn’s disease patients have major complications after infliximab withdrawal
About doi: 10.1016/j.cgh.2017.09.061).
, according to research published in the February issue of Clinical Gastroenterology and Hepatology (About 70% of patients remained free of both infliximab restart failure and major complications, said Catherine Reenaers, MD, PhD, of Centre Hospitalier Universitaire de Liège (Belgium), and her associates. Significant predictors of major complications included upper gastrointestinal disease at the time of infliximab withdrawal, white blood cell count of at least 5.0 x 109 per L, and hemoglobin level under 12.5 g per dL. “Patients with at least two of these factors had a more than 40% risk of major complication in the 7 years following infliximab withdrawal,” the researchers reported.
Little is known about long-term outcomes after patients with Crohn’s disease withdraw from infliximab. Therefore, Dr. Reenaers and her associates retrospectively studied 102 patients with Crohn’s disease who had received infliximab and an antimetabolite (azathioprine, mercaptopurine, or methotrexate) for at least 12 months, had been in steroid-free clinical remission for at least 6 months, and then withdrew from infliximab. Patients were recruited from 19 centers in Belgium and France and were originally part of a prospective cohort study of infliximab withdrawal in Crohn’s disease (Gastroenterology. 2012;142[1]:63-70.e5).
About half of patients relapsed and restarted infliximab within 12 months, which is in line with other studies, the researchers noted. Over a median follow-up of 83 months (interquartile range, 71-93 months), 21% (95% confidence interval, 13.1%-30.3%) of patients had no complications, did not restart infliximab, and started no other biologics. In all, 70.2% of patients (95% CI, 60.2%-80.1%) had no major complications and did not fail to respond after restarting infliximab.
Eighteen patients (19%; 95% CI, 10%-27%) developed major complications: 14 who required surgery and 4 who developed new complex perianal lesions. In a multivariable model, the strongest independent predictor of major complications was leukocytosis (hazard ratio, 10.5; 95% CI, 1.3-83; P less than .002), followed by upper gastrointestinal disease (HR, 5.8; 95% CI, 1.5-22) and low hemoglobin level (HR, 4.1; 95% CI, 1.5-21.8; P less than .01). The 13 patients who lacked these risk factors had no major complications of infliximab withdrawal. Among 72 patients who had at least one risk factor, 16.3% (95% CI, 7%-25%) developed major complications over 7 years. Strikingly, among 17 with at least two risk factors, 43% (95% CI, 17%-69%) developed major complications over 7 years, the researchers noted.
Complications emerged a median of 50 months (interquartile range, 41-73 months) after patients received their last infliximab infusion, highlighting the need for close long-term monitoring even if patients show no signs of early clinical relapse after infliximab withdrawal, the investigators said. “One strength of this cohort was the homogeneity of the population,” they stressed. “Most studies of anti–tumor necrosis factor withdrawal after clinical remission were limited by heterogeneous populations, variable lengths of infliximab treatment before discontinuation, and variable use of immunomodulators and corticosteroids. In [our] cohort, the population was homogenous, infliximab withdrawal was standardized, and the disease characteristics at the time of stopping were collected prospectively.” Although follow-up times varied, less than 5% of patients were followed for less than 3 years, they noted.
The researchers did not acknowledge external funding sources. Dr. Reenaers disclosed ties to AbbVie, Takeda, MSD, Mundipharma, Hospira, and Ferring.

The option of stopping a biologic agent is an attractive prospect for most Crohn's disease (CD) patients in stable clinical remission. The STORI trial, published in 2012, was among the earliest and select few studies addressing withdrawal of biologic therapy in CD among patients in sustained clinical remission with combination therapy (infliximab and thiopurine/methotrexate) for at least 6 months. Almost 50% of patients experienced disease relapse within a year of stopping infliximab in the trial.
Reenaers et al. recently published long-term follow-up of the original STORI cohort. After a median follow-up time of 7 years; four out five patients previously in clinical remission with combination therapy experienced worsening disease activity following withdrawal of infliximab. While the majority (70%) were able to resume infliximab and recapture disease response without any untoward adverse effects; one in five patients experienced major disease-related complications such as complex perianal disease or need for abdominal surgery. Upper GI tract involvement, high white blood cell count, and low hemoglobin concentration were associated with increased likelihood of a major complication. Notably, median time to a major complication was almost 4 years.
These results are similar to long-term relapse rates reported in other studies of withdrawal of therapy in CD. While biomarkers such as C-reactive protein, fecal calprotectin, along with endoscopic disease activity are reliable predictors of short-term relapse; clinical factors such as family history of CD, disease extent, stricturing or penetrating disease, and cigarette smoking are more relevant predictors of long-term disease activity. It is important to consider both types of predictors when considering withdrawal of therapy in CD.
Lastly, while the majority of patients who relapse following withdrawal of a biologic agent will do so within a year or two, a subset may not experience disease-related complications for several years - underscoring the need for long-term follow-up.

APOE4: Elders with allele benefit from lifestyle changes
“Whether such benefits are more pronounced in APOE4 carriers, compared with noncarriers, should be further investigated,” wrote Dr. Solomon of the Institute of Clinical Medicine/Neurology at the University of Eastern Finland, Kuopio, and her associates.
The investigators analyzed data of 1,109 participants in the multicenter Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER), a randomized, controlled trial of at-risk individuals from the general population. Participants were aged 60-77 years, and 362 of them were carriers of the APOE4 allele.
Those randomized to the intervention group received targeted information about nutrition, instructions about physical exercise, and cognitive training – including group sessions led by a psychologist. The control group received “regular health advice” (JAMA Neurol. 2018 Jan 22. doi: 10.1001/jamaneurol.2017.4365).
After the interventions, participants underwent a battery of neuropsychological testing. Dr. Solomon and her associates found that the per-year difference between the intervention and control groups in the total score change was 0.037 (95% confidence interval, 0.001-0.073) among APOE4 carriers and 0.014 (95% CI, −0.011-0.039) among noncarriers.
Among other things, the findings stress the importance of early prevention strategies targeting simultaneously many risk factors that are modifiable, the investigators said.

Preparing from the Outside Looking In for Safely Transitioning Pediatric Inpatients to Home
The transition of children from hospital to home introduces a unique set of challenges to patients and families who may not be well-versed in the healthcare system. In addition to juggling the stress and worry of a sick child, which can inhibit the ability to understand complicated discharge instructions prior to leaving the hospital,1 caregivers need to navigate the medical system to ensure continued recovery. The responsibility to fill and administer medications, arrange follow up appointments, and determine when to seek care if the child’s condition changes are burdens we as healthcare providers expect caregivers to manage but may underestimate how frequently they are reliably completed.2-4
In this issue of the Journal of Hospital Medicine, the article by Rehm et al.5 adds to the growing body of evidence highlighting challenges that caregivers of children face upon discharge from the hospital. The multicenter, retrospective study of postdischarge encounters for over 12,000 patients discharged from 4 children’s hospitals aimed to evaluate the following: (1) various methods for hospital-initiated postdischarge contact of families, (2) the type and frequency of postdischarge issues, and (3) specific characteristics of pediatric patients most commonly affected by postdischarge issues.
Using standardized questions administered through telephone, text, or e-mail contact, postdischarge issues were identified in 25% of discharges across all hospitals. Notably, there was considerable variation of rates of postdischarge issues among hospitals (from 16% to 62.8%). The hospital with the highest rate of postdischarge issues identified had attending hospitalists calling families after discharge. Thus, postdischarge issues may be most easily identified by providers who are familiar with both the patient and the expected postdischarge care.
Often, postdischarge issues represented events that could be mitigated with intentional planning to better anticipate and address patient and family needs prior to discharge. The vast majority of postdischarge issues identified across all hospitals were related to appointments, accounting for 76.3% of postdischarge issues, which may be attributed to a variety of causes, from inadequate or unclear provider recommendations to difficulty scheduling the appointments. The most common medication postdischarge issue was difficulty filling prescriptions, accounting for 84.8% of the medication issues. “Other” postdischarge issues (12.7%) as reported by caregivers included challenges with understanding discharge instructions and concerns about changes in their child’s clinical status. Forty percent of included patients had a chronic care condition. Older children, patients with more medication classes, shorter length of stay, and neuromuscular chronic care conditions had higher odds of postdischarge issues. Although a high proportion of postdischarge issues suggests a systemic problem addressing the needs of patients and families after hospital discharge, these data likely underestimate the magnitude of the problem; as such, the need for improvement may be higher.
Postdischarge challenges faced by families are not unique to pediatrics. Pediatric and adult medical patients face similar rates of challenges after
Given the prevalence of postdischarge issues after both pediatric and adult hospitalizations, how should hospitalists proceed? Physicians and health systems should explore approaches to better prepare caregivers, perhaps using models akin to the Seamless Transitions and (Re)admissions Network model of enhanced communication, care coordination, and family engagement.10 Pediatric hospitalists can prepare children for discharge long before departure by delivering medications to patients prior to discharge,11,12 providing discharge instructions that are clear and readable,13,14 as well as utilizing admission-discharge teaching nurses,15 inpatient care managers,16,17 and pediatric nurse practitioners18 to aid transition.
While a variety of interventions show promise in securing a successful transition to home from the hospitalist vantage point, a partnership with primary care physicians (PCPs) in our communities is paramount. Though the evidence linking gaps in primary care after discharge and readmission rates remain elusive, effective partnerships with PCPs are important for ensuring discharge plans are carried out, which may ultimately lead to decreased rates of unanticipated adverse outcomes. Several adult studies note that no single intervention is likely to prevent issues after discharge, but interventions should include high-quality communication with and involvement of community partners.9,19,20 In practice, providing a high-quality, reliable handoff can be difficult given competing priorities of busy outpatient clinic schedules and inpatient bed capacity concerns, necessitating efficient discharge practices. Some of these challenges are amenable to quality improvement efforts to improve discharge communication.21 Innovative ideas include collaborating with PCPs earlier in the admission to design the care plan up front, including PCPs in weekly team meetings for patients with chronic care conditions,16,17 and using telehealth to communicate with PCPs.
Ensuring a safe transition to home is our responsibility as hospitalists, but the solutions to doing so reliably require multi-fold interventions that build teams within hospitals, innovative outreach to those patients recently discharged to ensure their well-being and mitigate postdischarge issues and broad community programs—including greater access to primary care—to meet our urgent imperative.

The transition of children from hospital to home introduces a unique set of challenges to patients and families who may not be well-versed in the healthcare system. In addition to juggling the stress and worry of a sick child, which can inhibit the ability to understand complicated discharge instructions prior to leaving the hospital,1 caregivers need to navigate the medical system to ensure continued recovery. The responsibility to fill and administer medications, arrange follow up appointments, and determine when to seek care if the child’s condition changes are burdens we as healthcare providers expect caregivers to manage but may underestimate how frequently they are reliably completed.2-4
In this issue of the Journal of Hospital Medicine, the article by Rehm et al.5 adds to the growing body of evidence highlighting challenges that caregivers of children face upon discharge from the hospital. The multicenter, retrospective study of postdischarge encounters for over 12,000 patients discharged from 4 children’s hospitals aimed to evaluate the following: (1) various methods for hospital-initiated postdischarge contact of families, (2) the type and frequency of postdischarge issues, and (3) specific characteristics of pediatric patients most commonly affected by postdischarge issues.
Using standardized questions administered through telephone, text, or e-mail contact, postdischarge issues were identified in 25% of discharges across all hospitals. Notably, there was considerable variation of rates of postdischarge issues among hospitals (from 16% to 62.8%). The hospital with the highest rate of postdischarge issues identified had attending hospitalists calling families after discharge. Thus, postdischarge issues may be most easily identified by providers who are familiar with both the patient and the expected postdischarge care.

Accuracy Comparisons between Manual and Automated Respiratory Rate for Detecting Clinical Deterioration in Ward Patients
Respiratory rate is the most accurate vital sign for predicting adverse outcomes in ward patients.1,2 Though other vital signs are typically collected by using machines, respiratory rate is collected manually by caregivers counting the breathing rate. However, studies have shown significant discrepancies between a patient’s respiratory rate documented in the medical record, which is often 18 or 20, and the value measured by counting the rate over a full minute.3 Thus, despite the high accuracy of respiratory rate, it is possible that these values do not represent true patient physiology. It is unknown whether a valid automated measurement of respiratory rate would be more predictive than a manually collected respiratory rate for identifying patients who develop deterioration. The aim of this study was to compare the distribution and predictive accuracy of manually and automatically recorded respiratory rates.
METHODS
In this prospective cohort study, adult patients admitted to one oncology ward at the University of Chicago from April 2015 to May 2016 were approached for consent (Institutional Review Board #14-0682). Enrolled patients were fit with a cableless, FDA-approved respiratory pod device (Philips IntelliVue clResp Pod; Philips Healthcare, Andover, MA) that automatically recorded respiratory rate and heart rate every 15 minutes while they remained on the ward. Pod data were paired with vital sign data documented in the electronic health record (EHR) by taking the automated value closest, but prior to, the manual value up to a maximum of 4 hours. Automated and manual respiratory rate were compared by using the area under the receiver operating characteristic curve (AUC) for whether an intensive care unit (ICU) transfer occurred within 24 hours of each paired observation without accounting for patient-level clustering.
RESULTS
DISCUSSION
In this prospective cohort study, we found that manual respiratory rates were different than those collected from an automated system and, yet, were significantly more accurate for predicting ICU transfer. These results suggest that the predictive accuracy of respiratory rates documented in the EHR is due to more than just physiology. Our findings have important implications for the risk stratification of ward patients.
Though previous literature has suggested that respiratory rate is the most accurate predictor of deterioration, this may not be true.1 Respiratory rates manually recorded by clinical staff may contain information beyond pure physiology, such as a proxy of clinician concern, which may inflate the predictive value. Nursing staff may record standard respiratory rate values for patients that appear to be well (eg, 18) but count actual rates for those patients they suspect have a more severe disease, which is one possible explanation for our findings. In addition, automated assessments are likely to be more sensitive to intermittent fluctuations in respiratory rate associated with patient movement or emotion. This might explain the improved accuracy at higher rates for manually recorded vital signs.
Although limited by its small sample size, our results have important implications for patient monitoring and early warning scores designed to identify high-risk ward patients given that both simple scores and statistically derived models include respiratory rates as a predictor.4 As hospitals move to use newer technologies to automate vital sign monitoring and decrease nursing workload, our findings suggest that accuracy for identifying high-risk patients may be lost. Additional methods for capturing subjective assessments from clinical providers may be necessary and could be incorporated into risk scores.5 For example, the 7-point subjective Patient Acuity Rating has been shown to augment the Modified Early Warning Score for predicting ICU transfer, rapid response activation, or cardiac arrest within 24 hours.6
Manually recorded respiratory rate may include information beyond pure physiology, which inflates its predictive value. This has important implications for the use of automated monitoring technology in hospitals and the integration of these measurements into early warning scores.

It is unknown whether a valid automated measurement of respiratory rate would be more predictive than a manually collected respiratory rate for identifying patients who develop deterioration. The aim of this study was to compare the distribution and predictive accuracy of manually and automatically recorded respiratory rates.
METHODS
In this prospective cohort study, adult patients admitted to one oncology ward at the University of Chicago from April 2015 to May 2016 were approached for consent (Institutional Review Board #14-0682). Enrolled patients were fit with a cableless, FDA-approved respiratory pod device (Philips IntelliVue clResp Pod; Philips Healthcare, Andover, MA) that automatically recorded respiratory rate and heart rate every 15 minutes while they remained on the ward. Pod data were paired with vital sign data documented in the electronic health record (EHR) by taking the automated value closest, but prior to, the manual value up to a maximum of 4 hours. Automated and manual respiratory rate were compared by using the area under the receiver operating characteristic curve (AUC) for whether an intensive care unit (ICU) transfer occurred within 24 hours of each paired observation without accounting for patient-level clustering.
RESULTS
DISCUSSION
In this prospective cohort study, we found that manual respiratory rates were different than those collected from an automated system and, yet, were significantly more accurate for predicting ICU transfer. These results suggest that the predictive accuracy of respiratory rates documented in the EHR is due to more than just physiology. Our findings have important implications for the risk stratification of ward patients.
Though previous literature has suggested that respiratory rate is the most accurate predictor of deterioration, this may not be true.1 Respiratory rates manually recorded by clinical staff may contain information beyond pure physiology, such as a proxy of clinician concern, which may inflate the predictive value. Nursing staff may record standard respiratory rate values for patients that appear to be well (eg, 18) but count actual rates for those patients they suspect have a more severe disease, which is one possible explanation for our findings. In addition, automated assessments are likely to be more sensitive to intermittent fluctuations in respiratory rate associated with patient movement or emotion. This might explain the improved accuracy at higher rates for manually recorded vital signs.
Although limited by its small sample size, our results have important implications for patient monitoring and early warning scores designed to identify high-risk ward patients given that both simple scores and statistically derived models include respiratory rates as a predictor.4 As hospitals move to use newer technologies to automate vital sign monitoring and decrease nursing workload, our findings suggest that accuracy for identifying high-risk patients may be lost. Additional methods for capturing subjective assessments from clinical providers may be necessary and could be incorporated into risk scores.5 For example, the 7-point subjective Patient Acuity Rating has been shown to augment the Modified Early Warning Score for predicting ICU transfer, rapid response activation, or cardiac arrest within 24 hours.6
Manually recorded respiratory rate may include information beyond pure physiology, which inflates its predictive value. This has important implications for the use of automated monitoring technology in hospitals and the integration of these measurements into early warning scores.

Lean-Based Redesign of Multidisciplinary Rounds on General Medicine Service
Given that multiple disciplines are often involved in caring for patients admitted to the hospital, timely communication, collaboration, and coordination amongst various disciplines is necessary for safe and effective patient care.1 With the focus on improving patient satisfaction and throughput in hospitals, it is also important to make more accurate predictions of the discharge date and allow time for patients and their families to prepare for discharge.2-4
Multidisciplinary rounds (MDR) are defined as structured daily communication amongst key members of the patient’s care team (eg, nurses, physicians, case managers, social workers, pharmacists, and rehabilitation services). MDR have shown to be a useful strategy for ensuring that all members of the care team are updated on the plan of care for the patient.5 During MDR, a brief “check-in” discussing the patient’s plan of care, pending needs, and barriers to discharge allows all team members, patients, and families to effectively coordinate care and plan and prepare for discharge.
Multiple studies have reported increased collaboration and improved communication between disciplines with the use of such multidisciplinary rounding.2,5-7 Additionally, MDR have been shown to improve patient outcomes8 and reduce adverse events,9 length of stay (LOS),6,8 cost of care,8 and readmissions.1
We redesigned MDR on the general medicine wards at our institution in October 2014 by using Lean management techniques. Lean is defined as a set of philosophies and methods that aim to create transformation in thinking, behavior, and culture in each process, with the goal of maximizing the value for the patients and providers, adding efficiency, and reducing waste and waits.10
In this study, we evaluate whether this new model of MDR was associated with a decrease in the LOS. We also evaluate whether this new model of MDR was associated with an increase in discharges before noon, documentation of estimated discharge date (EDD) in our electronic health record (EHR), and patient satisfaction.
METHODS
Setting, Design, and Patients
The study was conducted on the teaching general medicine service at our institution, an urban, 484-bed academic hospital. The general medicine service has patients on 4 inpatient units (total of 95 beds) and is managed by 5 teaching service teams.
We performed a pre-post study. The preperiod (in which the old model of MDR was followed) included 4000 patients discharged between September 1, 2013, and October 22, 2014. The postperiod (in which the new model of MDR was followed) included 2085 patients discharged between October 23, 2014, and April 30, 2015. We excluded 139 patients that died in the hospital prior to discharge and patients on the nonteaching and/or private practice service.
All data were provided by our institution’s Digital Solutions Department. Our institutional review board issued a letter of determination exempting this study from further review because it was deemed to be a quality improvement initiative.
Use of Lean Management to Redesign our MDR
Our institution has incorporated the Lean management system to continually add value to services through the elimination of waste, thus simultaneously optimizing the quality of patient care, cost, and patient satisfaction.11 Lean, derived from the Toyota Production System, has long been used in manufacturing and in recent decades has spread to healthcare.12 We leveraged the following 3 key Lean techniques to redesign our MDR: (1) value stream management (VSM), (2) rapid process improvement workshops (RPIW), and (3) active daily management (ADM), as detailed in supplementary Appendix 1.
Interventions
Outcomes
The primary outcome was mean LOS. The secondary outcomes were (1) discharges before noon, (2) recording of the EDD in our EHR within 24 hours of admission (as time stamped on our EHR), and (3) patient satisfaction.
Data for patient satisfaction were obtained using the Press Ganey survey. We used data on patient satisfaction scores for the following 2 relevant questions on this survey: (1) extent to which the patient felt ready to be discharged and (2) how well staff worked together to care for the patient. Proportions of the “top-box” (“very good”) were used for the analysis. These survey data were available on 467 patients (11.7%) in the preperiod and 188 patients (9.0%) in the postperiod.
Data Analysis
A sensitivity analysis was conducted on a second cohort that included a subset of patients from the preperiod between November 1, 2013, and April 30, 2014, and a subset of patients from the postperiod between November 1, 2014, and April 1, 2015, to control for the calendar period (supplementary Appendix 2).
All analyses were conducted in R version 3.3.0, with the linear mixed-effects model lme4 statistical package.13,14
RESULTS
Table 3 shows the differences in the outcomes between the pre- and postperiods. There was no change in the LOS or LOS adjusted for CMI. There was a 3.9% increase in discharges before noon in the postperiod compared with the preperiod (95% CI, 2.4% to 5.3%; P < .001). There was a 9.9% increase in the percentage of patients for whom the EDD was recorded in our EHR within 24 hours of admission (95% CI, 7.4% to 12.4%; P < .001). There was no change in the “top-box” patient satisfaction scores.
There were only marginal differences in the results between the entire cohort and a second subset cohort used for sensitivity analysis (supplementary Appendix 2).
DISCUSSION
In our study, there was no change in the mean LOS with the new model of MDR. There was an increase in discharges before noon and in recording of the EDD in our EHR within 24 hours of admission in the postperiod when the Lean-based new model of MDR was utilized. There was no change in patient satisfaction. With no change in staffing, we were able to accommodate the increase in the discharge volume in the postperiod.
We believe our results are attributable to several factors, including clearly defined roles and responsibilities for all participants of MDR, the inclusion of more experienced general medicine attending physician (compared with housestaff), Lean management techniques to identify gaps in the patient’s journey from emergency department to discharge using VSM, the development of appropriate workflows and standard work on how the multidisciplinary teams would work together at RPIWs, and ADM to ensure sustainability and engagement among frontline members and institutional leaders. In order to sustain this, we planned to continue monitoring data in daily, weekly, and monthly forums with senior physician and administrative leaders. Planning for additional interventions is underway, including moving MDR to the bedside, instituting an afternoon “check-in” that would enable more detailed action planning, and addressing barriers in a timely manner for patients ready to discharge the following day.
Our study has a few limitations. First, this is an observational study that cannot determine causation. Second, this is a single-center study conducted on patients only on the general medicine teaching service. Third, there were several concurrent interventions implemented at our institution to improve LOS, throughput, and patient satisfaction in addition to MDR, thus making it difficult to isolate the impact of our intervention. Fourth, in the new model of MDR, rounds took place only 5 days per week, thereby possibly limiting the potential impact on our outcomes. Fifth, while we showed improvements in the discharges before noon and recording of EDD in the post period, we were not able to achieve our target of 25% discharges before noon or 100% recording of EDD in this time period. We believe the limited amount of time between the pre- and postperiods to allow for adoption and learning of the processes might have contributed to the underestimation of the impact of the new model of MDR, thereby limiting our ability to achieve our targets. Sixth, the response rate on the Press Ganey survey was low, and we did not directly survey patients or families for their satisfaction with MDR.
Our study has several strengths. To our knowledge, this is the first study to embed Lean management techniques in the design of MDR in the inpatient setting. While several studies have demonstrated improvements in discharges before noon through the implementation of MDR, they have not incorporated Lean management techniques, which we believe are critical to ensure the sustainability of results.1,3,5,6,8,15 Second, while it was not measured, there was a high level of provider engagement in the process in the new model of MDR. Third, because the MDR were conducted at the nurse’s station on each inpatient unit in the new model instead of in a conference room, it was well attended by all members of the multidisciplinary team. Fourth, the presence of a visibility board allowed for all team members to have easy access to visual feedback throughout the day, even if they were not present at the MDR. Fifth, we believe that there was also more accurate estimation of the date and time of discharge in the new model of MDR because the discussion was facilitated by the case manager, who is experienced in identifying barriers to discharge (compared with the housestaff in the old model of MDR), and included the more experienced attending physician. Finally, the consistent presence of a multidisciplinary team at MDR allowed for the incorporation of everyone’s concerns at one time, thereby limiting the need for paging multiple disciplines throughout the day, which led to quicker resolution of issues and assignment of pending tasks.
In conclusion, our study shows no change in the mean LOS when the Lean-based model of MDR was utilized. Our study demonstrates an increase in discharges before noon and in recording of EDD on our EHR within 24 hours of admission in the post period when the Lean-based model of MDR was utilized. There was no change in patient satisfaction. While this study was conducted at an academic medical center on the general medicine wards, we believe our new model of MDR, which leveraged Lean management techniques, may successfully impact patient flow in all inpatient clinical services and nonteaching hospitals.

While this study was conducted at an academic medical center on the general medicine wards, we believe our new model of MDR, which leveraged Lean management techniques, may successfully impact patient flow in all inpatient clinical services and nonteaching hospitals.

Given that multiple disciplines are often involved in caring for patients admitted to the hospital, timely communication, collaboration, and coordination amongst various disciplines is necessary for safe and effective patient care.1 With the focus on improving patient satisfaction and throughput in hospitals, it is also important to make more accurate predictions of the discharge date and allow time for patients and their families to prepare for discharge.2-4
Multidisciplinary rounds (MDR) are defined as structured daily communication amongst key members of the patient’s care team (eg, nurses, physicians, case managers, social workers, pharmacists, and rehabilitation services). MDR have shown to be a useful strategy for ensuring that all members of the care team are updated on the plan of care for the patient.5 During MDR, a brief “check-in” discussing the patient’s plan of care, pending needs, and barriers to discharge allows all team members, patients, and families to effectively coordinate care and plan and prepare for discharge.
Multiple studies have reported increased collaboration and improved communication between disciplines with the use of such multidisciplinary rounding.2,5-7 Additionally, MDR have been shown to improve patient outcomes8 and reduce adverse events,9 length of stay (LOS),6,8 cost of care,8 and readmissions.1
We redesigned MDR on the general medicine wards at our institution in October 2014 by using Lean management techniques. Lean is defined as a set of philosophies and methods that aim to create transformation in thinking, behavior, and culture in each process, with the goal of maximizing the value for the patients and providers, adding efficiency, and reducing waste and waits.10
In this study, we evaluate whether this new model of MDR was associated with a decrease in the LOS. We also evaluate whether this new model of MDR was associated with an increase in discharges before noon, documentation of estimated discharge date (EDD) in our electronic health record (EHR), and patient satisfaction.
METHODS
Setting, Design, and Patients
The study was conducted on the teaching general medicine service at our institution, an urban, 484-bed academic hospital. The general medicine service has patients on 4 inpatient units (total of 95 beds) and is managed by 5 teaching service teams.
We performed a pre-post study. The preperiod (in which the old model of MDR was followed) included 4000 patients discharged between September 1, 2013, and October 22, 2014. The postperiod (in which the new model of MDR was followed) included 2085 patients discharged between October 23, 2014, and April 30, 2015. We excluded 139 patients that died in the hospital prior to discharge and patients on the nonteaching and/or private practice service.
All data were provided by our institution’s Digital Solutions Department. Our institutional review board issued a letter of determination exempting this study from further review because it was deemed to be a quality improvement initiative.
Use of Lean Management to Redesign our MDR
Our institution has incorporated the Lean management system to continually add value to services through the elimination of waste, thus simultaneously optimizing the quality of patient care, cost, and patient satisfaction.11 Lean, derived from the Toyota Production System, has long been used in manufacturing and in recent decades has spread to healthcare.12 We leveraged the following 3 key Lean techniques to redesign our MDR: (1) value stream management (VSM), (2) rapid process improvement workshops (RPIW), and (3) active daily management (ADM), as detailed in supplementary Appendix 1.
Interventions
Outcomes
The primary outcome was mean LOS. The secondary outcomes were (1) discharges before noon, (2) recording of the EDD in our EHR within 24 hours of admission (as time stamped on our EHR), and (3) patient satisfaction.
Data for patient satisfaction were obtained using the Press Ganey survey. We used data on patient satisfaction scores for the following 2 relevant questions on this survey: (1) extent to which the patient felt ready to be discharged and (2) how well staff worked together to care for the patient. Proportions of the “top-box” (“very good”) were used for the analysis. These survey data were available on 467 patients (11.7%) in the preperiod and 188 patients (9.0%) in the postperiod.
Data Analysis
A sensitivity analysis was conducted on a second cohort that included a subset of patients from the preperiod between November 1, 2013, and April 30, 2014, and a subset of patients from the postperiod between November 1, 2014, and April 1, 2015, to control for the calendar period (supplementary Appendix 2).
All analyses were conducted in R version 3.3.0, with the linear mixed-effects model lme4 statistical package.13,14
RESULTS
Table 3 shows the differences in the outcomes between the pre- and postperiods. There was no change in the LOS or LOS adjusted for CMI. There was a 3.9% increase in discharges before noon in the postperiod compared with the preperiod (95% CI, 2.4% to 5.3%; P < .001). There was a 9.9% increase in the percentage of patients for whom the EDD was recorded in our EHR within 24 hours of admission (95% CI, 7.4% to 12.4%; P < .001). There was no change in the “top-box” patient satisfaction scores.
There were only marginal differences in the results between the entire cohort and a second subset cohort used for sensitivity analysis (supplementary Appendix 2).
DISCUSSION
In our study, there was no change in the mean LOS with the new model of MDR. There was an increase in discharges before noon and in recording of the EDD in our EHR within 24 hours of admission in the postperiod when the Lean-based new model of MDR was utilized. There was no change in patient satisfaction. With no change in staffing, we were able to accommodate the increase in the discharge volume in the postperiod.
We believe our results are attributable to several factors, including clearly defined roles and responsibilities for all participants of MDR, the inclusion of more experienced general medicine attending physician (compared with housestaff), Lean management techniques to identify gaps in the patient’s journey from emergency department to discharge using VSM, the development of appropriate workflows and standard work on how the multidisciplinary teams would work together at RPIWs, and ADM to ensure sustainability and engagement among frontline members and institutional leaders. In order to sustain this, we planned to continue monitoring data in daily, weekly, and monthly forums with senior physician and administrative leaders. Planning for additional interventions is underway, including moving MDR to the bedside, instituting an afternoon “check-in” that would enable more detailed action planning, and addressing barriers in a timely manner for patients ready to discharge the following day.
Our study has a few limitations. First, this is an observational study that cannot determine causation. Second, this is a single-center study conducted on patients only on the general medicine teaching service. Third, there were several concurrent interventions implemented at our institution to improve LOS, throughput, and patient satisfaction in addition to MDR, thus making it difficult to isolate the impact of our intervention. Fourth, in the new model of MDR, rounds took place only 5 days per week, thereby possibly limiting the potential impact on our outcomes. Fifth, while we showed improvements in the discharges before noon and recording of EDD in the post period, we were not able to achieve our target of 25% discharges before noon or 100% recording of EDD in this time period. We believe the limited amount of time between the pre- and postperiods to allow for adoption and learning of the processes might have contributed to the underestimation of the impact of the new model of MDR, thereby limiting our ability to achieve our targets. Sixth, the response rate on the Press Ganey survey was low, and we did not directly survey patients or families for their satisfaction with MDR.
Our study has several strengths. To our knowledge, this is the first study to embed Lean management techniques in the design of MDR in the inpatient setting. While several studies have demonstrated improvements in discharges before noon through the implementation of MDR, they have not incorporated Lean management techniques, which we believe are critical to ensure the sustainability of results.1,3,5,6,8,15 Second, while it was not measured, there was a high level of provider engagement in the process in the new model of MDR. Third, because the MDR were conducted at the nurse’s station on each inpatient unit in the new model instead of in a conference room, it was well attended by all members of the multidisciplinary team. Fourth, the presence of a visibility board allowed for all team members to have easy access to visual feedback throughout the day, even if they were not present at the MDR. Fifth, we believe that there was also more accurate estimation of the date and time of discharge in the new model of MDR because the discussion was facilitated by the case manager, who is experienced in identifying barriers to discharge (compared with the housestaff in the old model of MDR), and included the more experienced attending physician. Finally, the consistent presence of a multidisciplinary team at MDR allowed for the incorporation of everyone’s concerns at one time, thereby limiting the need for paging multiple disciplines throughout the day, which led to quicker resolution of issues and assignment of pending tasks.
In conclusion, our study shows no change in the mean LOS when the Lean-based model of MDR was utilized. Our study demonstrates an increase in discharges before noon and in recording of EDD on our EHR within 24 hours of admission in the post period when the Lean-based model of MDR was utilized. There was no change in patient satisfaction. While this study was conducted at an academic medical center on the general medicine wards, we believe our new model of MDR, which leveraged Lean management techniques, may successfully impact patient flow in all inpatient clinical services and nonteaching hospitals.

Issues Identified by Postdischarge Contact after Pediatric Hospitalization: A Multisite Study
Many hospitals are considering or currently employing initiatives to contact patients after discharge. Whether conducted via telephone or other means, the purpose of the contact is to help patients adhere to discharge plans, fulfill discharge needs, and alleviate postdischarge issues (PDIs). The effectiveness of hospital-initiated postdischarge phone calls has been studied in adult patients after hospitalization, and though some studies report positive outcomes,1-3 a 2006 Cochrane review found insufficient evidence to recommend for or against the practice.4
Little is known about follow-up contact after hospitalization for children.5-11 Rates of PDI vary substantially across hospitals. For example, one single-center study of postdischarge telephone contact after hospitalization on a general pediatric ward identified PDIs in ~20% of patients.10 Another study identified PDIs in 84% of patients discharged from a pediatric rehabilitation facility.11 Telephone follow-up has been associated with reduced health resource utilization and improved patient satisfaction for children discharged after an elective surgical procedure6 and for children discharged home from the emergency department.7-9
More information is needed on the clinical experiences of postdischarge contact in hospitalized children to improve the understanding of how the contact is made, who makes it, and which patients are most likely to report a PDI. These experiences are crucial to understand given the expense and time commitment involved in postdischarge contact, as many hospitals may not be positioned to contact all discharged patients. Therefore, we conducted a pragmatic, retrospective, naturalistic study of differing approaches to postdischarge contact occurring in multiple hospitals. Our main objective was to describe the prevalence and types of PDIs identified by the different approaches for follow-up contact across 4 children’s hospitals. We also assessed the characteristics of children who have the highest likelihood of having a PDI identified from the contact within each hospital.
METHODS
Study Design, Setting, and Population
Main Outcome Measures
The main outcome measure was identification of a PDI, defined as a medication, appointment, or other discharge-related issue, that was reported and recorded by the child’s caregiver during conversation from the standardized questions that were asked during follow-up contact as part of routine discharge care (Table 1). Medication PDIs included issues filling prescriptions and tolerating medications. Appointment PDIs included not having a follow-up appointment scheduled. Other PDIs included issues with the child’s health condition, discharge instructions, or any other concerns. All PDIs had been recorded prospectively by hospital contact personnel (hospitals A, B, and D) or through an automated texting system into a database (hospital C). Where available, free text comments that were recorded by contact personnel were reviewed by one of the authors (KB) and categorized via an existing framework of PDI designed by Heath et al.10 in order to further understand the problems that were reported.
Patient Characteristics
Patient hospitalization, demographic, and clinical characteristics were obtained from administrative health data at each institution and compared between children with versus without a PDI. Hospitalization characteristics included length of stay, season of admission, and reason for admission. Reason for admission was categorized by using 3M Health’s All Patient Refined Diagnosis Related Groups (APR-DRG) (3M, Maplewood, MN). Demographic characteristics included age at admission in years, insurance type (eg, public, private, and other), and race/ethnicity (Asian/Pacific Islander, Hispanic, non-Hispanic black, non-Hispanic white, and other).
Clinical characteristics included a count of the different classes of medications (eg, antibiotics, antiepileptic medications, digestive motility medications, etc.) administered to the child during admission, the type and number of chronic conditions, and assistance with medical technology (eg, gastrostomy, tracheostomy, etc.). Except for medications, these characteristics were assessed with International Classification of Diseases, Ninth Revision-Clinical Modification (ICD-9-CM) diagnosis codes.
We used the Agency for Healthcare Research and Quality Chronic Condition Indicator classification system, which categorizes over 14,000 ICD-9-CM diagnosis codes into chronic versus nonchronic conditions to identify the presence and number of chronic conditions.12 Children hospitalized with a chronic condition were further classified as having a complex chronic condition (CCC) by using the ICD-9-CM diagnosis classification scheme of Feudtner et al.13 CCCs represent defined diagnosis groupings of conditions expected to last longer than 12 months and involve either multiple organ systems or a single organ system severely enough to require specialty pediatric care and hospitalization.13,14 Children requiring medical technology were identified by using ICD-9-CM codes indicating their use of a medical device to manage and treat a chronic illness (eg, ventricular shunt to treat hydrocephalus) or to maintain basic body functions necessary for sustaining life (eg a tracheostomy tube for breathing).15,16
Statistical Analysis
Given that the primary purpose for this study was to leverage the natural heterogeneity in the approach to follow-up contact across hospitals, we assessed and reported the prevalence and type of PDIs independently for each hospital. Relatedly, we assessed the relationship between patient characteristics and PDI likelihood independently within each hospital as well rather than pool the data and perform a central analysis across hospitals. Of note, APR-DRG and medication class were not assessed for hospital D, as this information was unavailable. We used χ2 tests for univariable analysis and logistic regression with a backwards elimination derivation process (for variables with P ≥ .05) for multivariable analysis; all patient demographic, clinical, and hospitalization characteristics were entered initially into the models. All statistical analyses were performed using SAS version 9.3 (SAS Institute, Cary, NC), and P < .05 was considered statistically significant. This study was approved by the institutional review board at all hospitals.
RESULTS
Study Population
There were 12,986 (51.4%) of 25,259 patients reached by follow-up contact after discharge across the 4 hospitals. Median age at admission for contacted patients was 4.0 years (interquartile range [IQR] 0-11). Of those contacted, 45.2% were female, 59.9% were non-Hispanic white, 51.0% used Medicaid, and 95.4% were discharged to home. Seventy-one percent had a chronic condition (of any complexity) and 40.8% had a CCC. Eighty percent received a prescribed medication during the hospitalization. Median (IQR) length of stay was 2.0 days (IQR 1-4 days). The top 5 most common reasons for admission were bronchiolitis (6.3%), pneumonia (6.2%), asthma (5.2%), seizure (4.9%), and tonsil and adenoid procedures (4.1%).
PDIs
Characteristics Associated with PDIs
Age
Older age was a consistent characteristic associated with PDIs in 3 hospitals. For example, PDI rates in children 10 to 18 years versus <1 year were 30.8% versus 21.4% (P < .001) in hospital A, 19.4% versus 13.7% (P = .002) in hospital B, and 70.3% versus 62.8% (P < .001) in hospital D. In multivariable analysis, age 10 to 18 years versus <1 year at admission was associated with an increased likelihood of PDI in hospital A (odds ratio [OR] 1.7; 95% CI, 1.4-2.0), hospital B (OR 1.4; 95% CI, 1.1-1.8), and hospital D (OR 1.7; 95% CI, 0.9-3.0) (Table 3 and Figure).
Medications
Length of Stay
Shorter length of stay was associated with PDI in 1 hospital. In hospital A, the PDI rate increased significantly (P < .001) from 19.0% to 33.9% as length of stay decreased from ≥7 days to ≤1 day (Table 3). In multivariable analysis, length of stay to ≤1 day versus ≥7 days was associated with increased likelihood of PDI (OR 2.1; 95% CI, 1.7-2.5) in hospital A (Table 3 and Figure).
CCCs
A neuromuscular CCC was associated with PDI in 2 hospitals. In hospital B, the PDI rate was higher in children with a neuromuscular CCC compared with a malignancy CCC (21.3% vs 11.2%). In hospital D, the PDI rates were higher in children with a neuromuscular CCC compared with a respiratory CCC (68.9% vs 40.6%) (Table 3). In multivariable analysis, children with versus without a neuromuscular CCC had an increased likelihood of PDI (OR 1.3; 95% CI, 1.0-1.7) in hospital B (Table 3 and Figure).
DISCUSSION
In this retrospective, pragmatic, multicentered study of follow-up contact with a standardized set of questions asked after discharge for hospitalized children, we found that PDIs were identified often, regardless of who made the contact or how the contact was made. The PDI rates varied substantially across hospitals and were likely influenced by the different follow-up approaches that were used. Most PDIs were related to appointments; fewer PDIs were related to medications and other problems. Older age, shorter length of stay, and neuromuscular CCCs were among the identified risk factors for PDIs.
Our assessment of PDIs was, by design, associated with variation in methods and approach for detection across sites. Further investigation is needed to understand how different approaches for follow-up contact after discharge may influence the identification of PDIs. For example, in the current study, the hospital with the highest PDI rate (hospital D) used hospitalists who provided inpatient care for the patient to make follow-up contact. Although not determined from the current study, this approach could have led the hospitalists to ask questions beyond the standardized ones when assessing for PDIs. Perhaps some of the hospitalists had a better understanding of how to probe for PDIs specific to each patient; this understanding may not have been forthcoming for staff in the other hospitals who were unfamiliar with the patients’ hospitalization course and medical history.
Similar to previous studies in adults, our study reported that appointment PDIs in children may be more common than other types of PDIs.17 Appointment PDIs could have been due to scheduling difficulties, inadequate discharge instructions, lack of adherence to recommended follow-up, or other reasons. Further investigation is needed to elucidate these reasons and to determine how to reduce PDIs related to postdischarge appointments. Some children’s hospitals schedule follow-up appointments prior to discharge to mitigate appointment PDIs that might arise.18 However, doing that for every hospitalized child is challenging, especially for very short admissions or for weekend discharges when many outpatient and community practices are not open to schedule appointments. Additional exploration is necessary to assess whether this might help explain why some children in the current study with a short versus long length of stay had a higher likelihood of PDI.
The rate of medication PDIs (5.2%) observed in the current study is lower than the rate that is reported in prior literature. Dudas et al.1 found that medication PDIs occurred in 21% of hospitalized adult patients. One reason for the lower rate of medication PDIs in children may be that they require the use of postdischarge medications less often than adults. Most medication PDIs in the current study involved problems filling a prescription. There was not enough information in the notes taken from the follow-up contact to distinguish the medication PDI etiologies (eg, a prescription was not sent from the hospital team to the pharmacy, prior authorization from an insurance company for a prescription was not obtained, the pharmacy did not stock the medication). To help overcome medication access barriers, some hospitals fill and deliver discharge medications to the patients’ bedside. One study found that children discharged with medication in hand were less likely to have emergency department revisits within 30 days of discharge.19 Further investigation is needed to assess whether initiatives like these help mitigate medication PDIs in children.
Hospitals may benefit from considering how risk factors for PDIs can be used to prioritize which patients receive follow-up contact, especially in hospitals where contact for all hospitalized patients is not feasible. In the current study, there was variation across hospitals in the profile of risk factors that correlated with increased likelihood of PDI. Some of the risk factors are easier to explain than others. For example, as mentioned above, for some hospitalized children, short length of stay might not permit enough time for hospital staff to set up discharge plans that may sufficiently prevent PDIs. Other risk factors, including older age and neuromuscular CCCs, may require additional assessment (eg, through chart review or in-depth patient and provider interviews) to discover the reasons why they were associated with increased likelihood of PDI. There are additional risk factors that might influence the likelihood of PDI that the current study was not positioned to assess, including health literacy, transportation availability, and language spoken.20-23
This study has several other limitations in addition to the ones already mentioned. Some children may have experienced PDIs that were not reported at contact (eg, the respondent was unaware that an issue was present), which may have led to an undercounting of PDIs. Alternatively, some caregivers may have been more likely to respond to the contact if their child was experiencing a PDI, which may have led to overcounting. PDIs of nonrespondents were not measured. PDIs identified by postdischarge outpatient and community providers or by families outside of contact were not measured. The current study was not positioned to assess the severity of the PDIs or what interventions (including additional health services) were needed to address them. Although we assessed medication use during admission, we were unable to assess the number and type of medications that were prescribed for use postdischarge. Information about the number and type of follow-up visits needed for each child was not assessed. Given the variety of approaches for follow-up contact, the findings may generalize best to individual hospitals by using an approach that best matches to one of them. The current study is not positioned to correlate quality of discharge care with the rate of PDI.
Despite these limitations, the findings from the current study reinforce that PDIs identified through follow-up contact in discharged patients appear to be common. Of PDIs identified, appointment problems were more prevalent than medication or other types of problems. Short length of stay, older age, and other patient and/or hospitalization attributes were associated with an increased likelihood of PDI. Hospitals caring for children may find this information useful as they strive to optimize their processes for follow-up contact after discharge. To help further evaluate the value and importance of contacting patients after discharge, additional study of PDI in children is warranted, including (1) actions taken to resolve PDIs, (2) the impact of identifying and addressing PDIs on hospital readmission, and (3) postdischarge experiences and health outcomes of children who responded versus those who did not respond to the follow-up contact. Moreover, future multisite, comparative effectiveness studies of PDI may wish to consider standardization of follow-up contact procedures with controlled manipulation of key processes (eg, contact by administrator vs nurse vs physician) to assess best practices.

Many hospitals are considering or currently employing initiatives to contact patients after discharge. Whether conducted via telephone or other means, the purpose of the contact is to help patients adhere to discharge plans, fulfill discharge needs, and alleviate postdischarge issues (PDIs). The effectiveness of hospital-initiated postdischarge phone calls has been studied in adult patients after hospitalization, and though some studies report positive outcomes,1-3 a 2006 Cochrane review found insufficient evidence to recommend for or against the practice.4
Little is known about follow-up contact after hospitalization for children.5-11 Rates of PDI vary substantially across hospitals. For example, one single-center study of postdischarge telephone contact after hospitalization on a general pediatric ward identified PDIs in ~20% of patients.10 Another study identified PDIs in 84% of patients discharged from a pediatric rehabilitation facility.11 Telephone follow-up has been associated with reduced health resource utilization and improved patient satisfaction for children discharged after an elective surgical procedure6 and for children discharged home from the emergency department.7-9
More information is needed on the clinical experiences of postdischarge contact in hospitalized children to improve the understanding of how the contact is made, who makes it, and which patients are most likely to report a PDI. These experiences are crucial to understand given the expense and time commitment involved in postdischarge contact, as many hospitals may not be positioned to contact all discharged patients. Therefore, we conducted a pragmatic, retrospective, naturalistic study of differing approaches to postdischarge contact occurring in multiple hospitals. Our main objective was to describe the prevalence and types of PDIs identified by the different approaches for follow-up contact across 4 children’s hospitals. We also assessed the characteristics of children who have the highest likelihood of having a PDI identified from the contact within each hospital.
METHODS
Study Design, Setting, and Population
Main Outcome Measures
The main outcome measure was identification of a PDI, defined as a medication, appointment, or other discharge-related issue, that was reported and recorded by the child’s caregiver during conversation from the standardized questions that were asked during follow-up contact as part of routine discharge care (Table 1). Medication PDIs included issues filling prescriptions and tolerating medications. Appointment PDIs included not having a follow-up appointment scheduled. Other PDIs included issues with the child’s health condition, discharge instructions, or any other concerns. All PDIs had been recorded prospectively by hospital contact personnel (hospitals A, B, and D) or through an automated texting system into a database (hospital C). Where available, free text comments that were recorded by contact personnel were reviewed by one of the authors (KB) and categorized via an existing framework of PDI designed by Heath et al.10 in order to further understand the problems that were reported.
Patient Characteristics
Patient hospitalization, demographic, and clinical characteristics were obtained from administrative health data at each institution and compared between children with versus without a PDI. Hospitalization characteristics included length of stay, season of admission, and reason for admission. Reason for admission was categorized by using 3M Health’s All Patient Refined Diagnosis Related Groups (APR-DRG) (3M, Maplewood, MN). Demographic characteristics included age at admission in years, insurance type (eg, public, private, and other), and race/ethnicity (Asian/Pacific Islander, Hispanic, non-Hispanic black, non-Hispanic white, and other).
Clinical characteristics included a count of the different classes of medications (eg, antibiotics, antiepileptic medications, digestive motility medications, etc.) administered to the child during admission, the type and number of chronic conditions, and assistance with medical technology (eg, gastrostomy, tracheostomy, etc.). Except for medications, these characteristics were assessed with International Classification of Diseases, Ninth Revision-Clinical Modification (ICD-9-CM) diagnosis codes.
We used the Agency for Healthcare Research and Quality Chronic Condition Indicator classification system, which categorizes over 14,000 ICD-9-CM diagnosis codes into chronic versus nonchronic conditions to identify the presence and number of chronic conditions.12 Children hospitalized with a chronic condition were further classified as having a complex chronic condition (CCC) by using the ICD-9-CM diagnosis classification scheme of Feudtner et al.13 CCCs represent defined diagnosis groupings of conditions expected to last longer than 12 months and involve either multiple organ systems or a single organ system severely enough to require specialty pediatric care and hospitalization.13,14 Children requiring medical technology were identified by using ICD-9-CM codes indicating their use of a medical device to manage and treat a chronic illness (eg, ventricular shunt to treat hydrocephalus) or to maintain basic body functions necessary for sustaining life (eg a tracheostomy tube for breathing).15,16
Statistical Analysis
Given that the primary purpose for this study was to leverage the natural heterogeneity in the approach to follow-up contact across hospitals, we assessed and reported the prevalence and type of PDIs independently for each hospital. Relatedly, we assessed the relationship between patient characteristics and PDI likelihood independently within each hospital as well rather than pool the data and perform a central analysis across hospitals. Of note, APR-DRG and medication class were not assessed for hospital D, as this information was unavailable. We used χ2 tests for univariable analysis and logistic regression with a backwards elimination derivation process (for variables with P ≥ .05) for multivariable analysis; all patient demographic, clinical, and hospitalization characteristics were entered initially into the models. All statistical analyses were performed using SAS version 9.3 (SAS Institute, Cary, NC), and P < .05 was considered statistically significant. This study was approved by the institutional review board at all hospitals.
RESULTS
Study Population
There were 12,986 (51.4%) of 25,259 patients reached by follow-up contact after discharge across the 4 hospitals. Median age at admission for contacted patients was 4.0 years (interquartile range [IQR] 0-11). Of those contacted, 45.2% were female, 59.9% were non-Hispanic white, 51.0% used Medicaid, and 95.4% were discharged to home. Seventy-one percent had a chronic condition (of any complexity) and 40.8% had a CCC. Eighty percent received a prescribed medication during the hospitalization. Median (IQR) length of stay was 2.0 days (IQR 1-4 days). The top 5 most common reasons for admission were bronchiolitis (6.3%), pneumonia (6.2%), asthma (5.2%), seizure (4.9%), and tonsil and adenoid procedures (4.1%).
PDIs
Characteristics Associated with PDIs
Age
Older age was a consistent characteristic associated with PDIs in 3 hospitals. For example, PDI rates in children 10 to 18 years versus <1 year were 30.8% versus 21.4% (P < .001) in hospital A, 19.4% versus 13.7% (P = .002) in hospital B, and 70.3% versus 62.8% (P < .001) in hospital D. In multivariable analysis, age 10 to 18 years versus <1 year at admission was associated with an increased likelihood of PDI in hospital A (odds ratio [OR] 1.7; 95% CI, 1.4-2.0), hospital B (OR 1.4; 95% CI, 1.1-1.8), and hospital D (OR 1.7; 95% CI, 0.9-3.0) (Table 3 and Figure).
Medications
Length of Stay
Shorter length of stay was associated with PDI in 1 hospital. In hospital A, the PDI rate increased significantly (P < .001) from 19.0% to 33.9% as length of stay decreased from ≥7 days to ≤1 day (Table 3). In multivariable analysis, length of stay to ≤1 day versus ≥7 days was associated with increased likelihood of PDI (OR 2.1; 95% CI, 1.7-2.5) in hospital A (Table 3 and Figure).
CCCs
A neuromuscular CCC was associated with PDI in 2 hospitals. In hospital B, the PDI rate was higher in children with a neuromuscular CCC compared with a malignancy CCC (21.3% vs 11.2%). In hospital D, the PDI rates were higher in children with a neuromuscular CCC compared with a respiratory CCC (68.9% vs 40.6%) (Table 3). In multivariable analysis, children with versus without a neuromuscular CCC had an increased likelihood of PDI (OR 1.3; 95% CI, 1.0-1.7) in hospital B (Table 3 and Figure).
DISCUSSION
In this retrospective, pragmatic, multicentered study of follow-up contact with a standardized set of questions asked after discharge for hospitalized children, we found that PDIs were identified often, regardless of who made the contact or how the contact was made. The PDI rates varied substantially across hospitals and were likely influenced by the different follow-up approaches that were used. Most PDIs were related to appointments; fewer PDIs were related to medications and other problems. Older age, shorter length of stay, and neuromuscular CCCs were among the identified risk factors for PDIs.
Our assessment of PDIs was, by design, associated with variation in methods and approach for detection across sites. Further investigation is needed to understand how different approaches for follow-up contact after discharge may influence the identification of PDIs. For example, in the current study, the hospital with the highest PDI rate (hospital D) used hospitalists who provided inpatient care for the patient to make follow-up contact. Although not determined from the current study, this approach could have led the hospitalists to ask questions beyond the standardized ones when assessing for PDIs. Perhaps some of the hospitalists had a better understanding of how to probe for PDIs specific to each patient; this understanding may not have been forthcoming for staff in the other hospitals who were unfamiliar with the patients’ hospitalization course and medical history.
Similar to previous studies in adults, our study reported that appointment PDIs in children may be more common than other types of PDIs.17 Appointment PDIs could have been due to scheduling difficulties, inadequate discharge instructions, lack of adherence to recommended follow-up, or other reasons. Further investigation is needed to elucidate these reasons and to determine how to reduce PDIs related to postdischarge appointments. Some children’s hospitals schedule follow-up appointments prior to discharge to mitigate appointment PDIs that might arise.18 However, doing that for every hospitalized child is challenging, especially for very short admissions or for weekend discharges when many outpatient and community practices are not open to schedule appointments. Additional exploration is necessary to assess whether this might help explain why some children in the current study with a short versus long length of stay had a higher likelihood of PDI.
The rate of medication PDIs (5.2%) observed in the current study is lower than the rate that is reported in prior literature. Dudas et al.1 found that medication PDIs occurred in 21% of hospitalized adult patients. One reason for the lower rate of medication PDIs in children may be that they require the use of postdischarge medications less often than adults. Most medication PDIs in the current study involved problems filling a prescription. There was not enough information in the notes taken from the follow-up contact to distinguish the medication PDI etiologies (eg, a prescription was not sent from the hospital team to the pharmacy, prior authorization from an insurance company for a prescription was not obtained, the pharmacy did not stock the medication). To help overcome medication access barriers, some hospitals fill and deliver discharge medications to the patients’ bedside. One study found that children discharged with medication in hand were less likely to have emergency department revisits within 30 days of discharge.19 Further investigation is needed to assess whether initiatives like these help mitigate medication PDIs in children.
Hospitals may benefit from considering how risk factors for PDIs can be used to prioritize which patients receive follow-up contact, especially in hospitals where contact for all hospitalized patients is not feasible. In the current study, there was variation across hospitals in the profile of risk factors that correlated with increased likelihood of PDI. Some of the risk factors are easier to explain than others. For example, as mentioned above, for some hospitalized children, short length of stay might not permit enough time for hospital staff to set up discharge plans that may sufficiently prevent PDIs. Other risk factors, including older age and neuromuscular CCCs, may require additional assessment (eg, through chart review or in-depth patient and provider interviews) to discover the reasons why they were associated with increased likelihood of PDI. There are additional risk factors that might influence the likelihood of PDI that the current study was not positioned to assess, including health literacy, transportation availability, and language spoken.20-23
This study has several other limitations in addition to the ones already mentioned. Some children may have experienced PDIs that were not reported at contact (eg, the respondent was unaware that an issue was present), which may have led to an undercounting of PDIs. Alternatively, some caregivers may have been more likely to respond to the contact if their child was experiencing a PDI, which may have led to overcounting. PDIs of nonrespondents were not measured. PDIs identified by postdischarge outpatient and community providers or by families outside of contact were not measured. The current study was not positioned to assess the severity of the PDIs or what interventions (including additional health services) were needed to address them. Although we assessed medication use during admission, we were unable to assess the number and type of medications that were prescribed for use postdischarge. Information about the number and type of follow-up visits needed for each child was not assessed. Given the variety of approaches for follow-up contact, the findings may generalize best to individual hospitals by using an approach that best matches to one of them. The current study is not positioned to correlate quality of discharge care with the rate of PDI.
Despite these limitations, the findings from the current study reinforce that PDIs identified through follow-up contact in discharged patients appear to be common. Of PDIs identified, appointment problems were more prevalent than medication or other types of problems. Short length of stay, older age, and other patient and/or hospitalization attributes were associated with an increased likelihood of PDI. Hospitals caring for children may find this information useful as they strive to optimize their processes for follow-up contact after discharge. To help further evaluate the value and importance of contacting patients after discharge, additional study of PDI in children is warranted, including (1) actions taken to resolve PDIs, (2) the impact of identifying and addressing PDIs on hospital readmission, and (3) postdischarge experiences and health outcomes of children who responded versus those who did not respond to the follow-up contact. Moreover, future multisite, comparative effectiveness studies of PDI may wish to consider standardization of follow-up contact procedures with controlled manipulation of key processes (eg, contact by administrator vs nurse vs physician) to assess best practices.
