Language difficulties persist until age 13 for very preterm infants

Article Type
Changed

Children born very preterm continue to display language difficulties compared with term controls at 13 years of age, with no evidence of developmental “catch up.”

Given the functional implications associated with language deficits, early language-based interventions should be considered for children born VP, investigators wrote in Pediatrics.

“Difficulties in language functioning in this cohort of children born VP remained stable from 2 to 13 years of age. Although generalized language deficits were observed, the VP group had marked difficulties on expressive components of language,” wrote Thi-Nhu-Ngoc Nguyen, BSc, of Monash University, Melbourne, and her associates.

Ms. Nguyen and associates assessed language skills using performance-based or parent-report measures in 244 children born VP (less than 30 weeks’ gestation) and 77 term controls, at 2, 5, 7, and 13 years of age. Compared with term controls, children born VP had poorer functioning across all components of language (mean group differences ranged from −0.5 SD to −1 SD; all P less than .05) at 13 years of age. At each follow-up age, the VP group displayed poorer language functioning than did the term controls, with the groups exhibiting similar developmental trajectories (slope difference = −0.01 SD per year; P = .55). “With our findings, we emphasize the need for effective and timely interventions for language skills in children born VP to close the gap with their term peers,” the investigators concluded.

Questionnaire Body

A 31-year-old man is brought to your facility by local law enforcement for evaluation of left wrist pain following an altercation. The patient was reportedly at a local bar; as he was leaving, he started arguing with some other patrons. A fight ensued.

The patient believes he was struck by something on his left wrist. He denies any other injuries or complaints. His medical history is unremarkable, and vital signs are stable.

Physical examination of his left wrist shows no obvious deformity. There is some mild swelling over the dorsal aspect of his wrist. Range of motion is painful and limited. Good capillary refill is noted in the fingers, and sensation is intact. Good pulses are present.

Radiograph of the left wrist is obtained. What is your impression?

Use of a risk score may be able to identify high-risk patients presenting with acute heart failure

Article Type
Changed

 

Clinical question: Can we use readily available data to risk stratify patients who present to the emergency department in acute heart failure (AHF)?

Background: Although cardiac biomarkers such as troponin and B-natriuretic peptide have general prognostic value in patients with AHF presenting to the emergency department, these values do not reliably aid in determining patients’ risk for unfavorable outcomes at the time of clinical decision making. Currently available published scores for risk-stratifying patients with AHF in the ED have limited applicability.

Dr. Noble Maleque
Study design: Prospective cohort study (with second validation cohort).

Setting: The registry included patients from 34 different hospitals in Spain.

Synopsis: This study analyzed clinical variables from a cohort of 4,897 AHF patients to determine predictors of patient outcomes. Thirteen clinical variables were identified as independent predictors of 30-day mortality and were incorporated into a risk score calculator (MEESSI-AHF). The risk score includes variables such as vital signs, age, labs values, and performance status. A second cohort of 3,229 patients were used to validate the risk score. The risk score effectively discriminates patients into low-, intermediate-, and high-risk patients. One important limitation is a high number of missing values in derivation cohort that required advanced statistics to overcome. The generalizability of the population studies (Spanish population) to other countries is still unclear. A risk score that can reasonably identify low-risk patients may be the most clinically useful in order to identify patients that either can be treated effectively in the emergency department and may not warrant inpatient admission.

Bottom line: The MEESSI-AHF risk score may be a helpful tool in identifying the risk of 30-day mortality in patients who present to the ED with AHF, but it is currently unclear if the score can be generalized to other populations.

Two scoring systems helpful in diagnosing heparin-induced thrombocytopenia

Article Type
Changed

– Both the 4Ts Score and the HIT Expert Probability (HEP) Score are useful in clinical practice for the diagnosis of heparin-induced thrombocytopenia, but the HEP score may have better operative characteristics in ICU patients, results from a “real world” analysis showed.

“The diagnosis of heparin-induced thrombocytopenia (HIT) is challenging,” Allyson M. Pishko, MD, one of the study authors, said at the biennial summit of the Thrombosis & Hemostasis Societies of North America. “The 4Ts Score is commonly used, but limitations include its low positive predictive value and significant interobserver variability.”

Dr. Allyson M. Pishko
The HEP Score, on the other hand, is based on the opinion of 26 HIT experts, said Dr. Pishko, a hematology/oncology fellow at the University of Pennsylvania. It contains eight categories with positive or negative points assigned within each category. Results from a single-center retrospective study showed a higher positive predictive value and less inter-rater variability, compared with the 4Ts Score (J Thromb Haemost 2010 Dec;8[12]:2642-50).

One external prospective study showed operating characteristics similar to those of 4Ts scores (Thromb Haemost 2015;113[3]:633-40).

The aim of the current study was to validate the HEP Score in a “real world” setting and to compare the performance of the HEP Score versus the 4Ts Score. The researchers enrolled 292 adults with suspected acute HIT who were hospitalized at the University of Pennsylvania or affiliated community hospitals, and who had HIT laboratory testing ordered.

The HEP Score and the 4Ts Score were calculated by a member of the clinical team and were completed prior to return of the HIT lab test result. The majority of scorers (62%) were hematology fellows, followed by attendings (35%), and residents/students (3%). All patients underwent testing with an HIT ELISA and serotonin-release assay (SRA). Patients in whom the optical density of the ELISA was less than 0.4 units were classified as not having HIT. The researchers used the Wilcoxon rank-sum test to compare HEP and 4Ts Scores in patients with and without HIT.

Of the 292 patients, 209 were HIT negative and 83 had their data reviewed by an expert panel. Of these 83 patients, 40 were found to be HIT negative and 43 were HIT positive, and their mean ages were 65 years and 63 years, respectively. Among the cases found to be positive for HIT, 93% had HIT ELISA optical density of 1 or greater and 69.7% were SRA positive. The median HEP Score in patients with and without HIT was 8 versus 5 (P less than .0001).
 

 


At the prespecified screening cut-off of 2 or more points, the HEP Score was 97.7% sensitive and 21.9% specific, with a positive predictive value of 17.7% and a negative predictive value of 98.2%. A cut-off of 5 or greater provided 90.7% sensitivity and 47.8% specificity with a positive predictive value of 23.1% and a negative predictive value of 96.8%. The mean time to calculate the HEP Score was 4.1 minutes.

The median 4Ts Score in patients with and without HIT was 5 versus 4 (P less than .0001), Dr. Pishko reported. A 4Ts Score of 4 or greater had a sensitivity of 97.7% and specificity of 32.9%, with a positive predictive value of 20.1% and a negative predictive value of 98.8%.

The area under the ROC curves for the HEP Score and 4Ts Score were similar (0.81 vs. 0.76; P = .121). Subset analysis revealed that compared with the 4Ts Score, the HEP Score had better operating characteristics in ICU patients (AUC 0.87 vs. 0.79; P= .029) and with trainee scorers (AUC 0.79 vs. 0.73; P = .032).

“Our data suggest that either the HEP Score or the 4Ts Score could be used in clinical practice,” Dr. Pishko said.

The National Institutes of Health funded the study. Dr. Pishko reported having no financial disclosures.

Boosting bedside skills in hands-on session

Article Type
Changed

A low faculty-to-learner ratio helped HM18 attendees get the most from their learning experience in the Sunday pre-conference course “Bedside Procedures for the Hospitalist.”

The pre-course blended live didactic teaching and hands-on training with simulators so participants could not only learn but also review and demonstrate techniques for many common invasive procedures hospitalists encounter in practice.

“Our goal is to make the entire bedside procedures pre-course a unique experience,” course codirector Alyssa Burk­hart, MD, of the Billings (Mont.) Clinic, said in an interview before the session.

Dr. Alyssa Burkhart


“We carefully select the curriculum to create a program most relevant to the participants and their day-to-day work in patient care,” said Dr. Burkhart.

“The low faculty-to-learner ratio coupled with ample time to practice under expert guidance separates us from others. ... It’s a privilege to share our love of procedures with this year’s SHM participants,” said Dr. Burkhart, who comoderated the session with Joshua Lenchus, DO, SFHM, of the University of Miami.
Dr. Joshua Lenchus


An interactive focus on bedside procedures benefits novices and experienced clinicians, said Dr. Lenchus.

The simulation experience involved practice with ultrasound as well as anatomically representative training equipment.
 

 


“Our hope is that many hospitalists may once again find that spark of interest in performing more of their own procedures. The interactive sessions embedded within the pre-course are vital to the success of our program. Many other training sessions are didactics based. We strive to keep lecture time to a minimum so that small groups can learn from the expert facilitators,” Dr. Burkhart added.

“Ample hands-on practice time, interactive experience, and direct supervision separate our pre-course from other commercially available offerings,” Dr. Lenchus said.

The agenda kicked off with vascular and intraosseous access in the morning, followed by paracentesis, thoracentesis, lumbar puncture, and basic airway management, including the use of supraglottic devices.

Dr. Burkhart noted that the course included two separate practice sessions for vascular access because of the number of technical steps and potential complications. “Attendees typically wish to spend a considerable amount of time on vascular access,” she said. “The intraosseous access station and its exceptional trainers always receive very positive feedback.”

Dr. Burkhart and Dr. Lenchus had no financial conflicts to disclose.

It’s a privilege to share our love of procedures with this year’s SHM participants,” said Dr. Burkhart, who comoderated the session with Joshua Lenchus, DO, SFHM, of the University of Miami.

An interactive focus on bedside procedures benefits novices and experienced clinicians, said Dr. Lenchus.

The simulation experience involved practice with ultrasound as well as anatomically representative training equipment.
 

 


“Our hope is that many hospitalists may once again find that spark of interest in performing more of their own procedures. The interactive sessions embedded within the pre-course are vital to the success of our program. Many other training sessions are didactics based. We strive to keep lecture time to a minimum so that small groups can learn from the expert facilitators,” Dr. Burkhart added.

“Ample hands-on practice time, interactive experience, and direct supervision separate our pre-course from other commercially available offerings,” Dr. Lenchus said.

The agenda kicked off with vascular and intraosseous access in the morning, followed by paracentesis, thoracentesis, lumbar puncture, and basic airway management, including the use of supraglottic devices.

Dr. Burkhart noted that the course included two separate practice sessions for vascular access because of the number of technical steps and potential complications. “Attendees typically wish to spend a considerable amount of time on vascular access,” she said. “The intraosseous access station and its exceptional trainers always receive very positive feedback.”

Dr. Burkhart and Dr. Lenchus had no financial conflicts to disclose.

A low faculty-to-learner ratio helped HM18 attendees get the most from their learning experience in the Sunday pre-conference course “Bedside Procedures for the Hospitalist.”

The pre-course blended live didactic teaching and hands-on training with simulators so participants could not only learn but also review and demonstrate techniques for many common invasive procedures hospitalists encounter in practice.

“Our goal is to make the entire bedside procedures pre-course a unique experience,” course codirector Alyssa Burk­hart, MD, of the Billings (Mont.) Clinic, said in an interview before the session.

Practical changes for improving practice management

Article Type
Changed

An all-day HM18 pre-course – “Hospitalist Practice Management: How to Thrive in a Time of Intense Change” – for hospitalist leaders and practice administrators was all about practicality.

One of the goals of the session was to provide “quick, actionable interventions that attendees can implement right away, as well as alternatives for attendees to consider, which will require some work to employ,” said John Nelson, MD, MHM, a partner at Nelson Flores Hospital Medicine Consultants, La Quinta, Calif., the medical director of the Overlake Medical Center, Bellevue, Wash., and a course codirector and a faculty presenter.

Dr. John Nelson
Session speakers addressed strategies to help position a hospitalist group for success, “which we define as having happy physicians and other providers, good metrics performance, and good financial performance,” Dr. Nelson, a cofounder and past president of SHM, said in an interview before the pre-course.

Dr. Nelson pointed out that the hospitalist practice is a unique practice model. “We can’t effectively use the same approaches that other medical specialties use to ensure we have successful practices,” he said.

The pre-course, held Sunday before the official start of HM18, included more commentary and specifics than in past years about how to prosper in the rapidly changing health care landscape and how to reduce the chance of burnout.

Leslie Flores
“Our goal is to help hospitalist groups put the right operational framework and infrastructure into place so they can be successful in taking care of patients and deliver value to institutions where they work,” Leslie Flores, MHA, SFHM, a partner at Nelson Flores Hospital Medicine Consultants, who was the course codirector, said in an interview before the session.

Topics addressed included how to find, measure, and demonstrate value; how to incorporate different types of providers and clinical support staffing into a practice to support hospitalists; and how to recruit the right people and build a desirable culture.
 

 


The pre-course also covered effective roles for a variety of providers in a hospitalist group, including nurses, scribes, and coordinators, and delineated the benefits of providing telemedicine.

For group leaders and administrators in attendance, the session also shed light on how to interact with individual providers in their group and how to collaborate to build a healthy culture and practice, Ms. Flores said.

The day began with presentations that laid out valuable information and frameworks, including “A Tour of Survey Data: What It Does and Doesn’t Tell You” and “Defining and Measuring Value.” Sessions included six didactic lectures with a question-and-answer period, as well as what Dr. Nelson has dubbed “point/counterpoint” sessions in which faculty members debated particular issues, such as work scheduling models. During the last session, “Learning From Each Other,” participants shared with other attendees their own best practices in the areas covered.

Although there is no single best way to organize a hospitalist’s practice, the course provided lots of information and perspective to help listeners decide what is best for their practice.

“Even though we work in a stressful environment of constant change, hospitalists do have some control over their destiny, and there are things they can do to make hospitalist groups thrive in this challenging environment,” Ms. Flores concluded.

Journal of Hospital Medicine releases consensus statement on inpatient opioid prescribing

Article Type
Changed
Bolstering prescribing practices to improve patient outcomes.

The Journal of Hospital Medicine, the official peer-reviewed journal of the Society of Hospital Medicine, has released a statement titled “Improving the Safety of Opioid Use for Acute Noncancer Pain in Hospitalized Adults: A Consensus Statement from the Society of Hospital Medicine” in response to the growing issue of managing opioid prescribing in the inpatient setting.

The statement offers 16 recommendations covering whether to use opioids in the hospital and how to improve the safety of opioid prescribing both during hospitalization and at discharge. The statement is available in the April 2018 issue of the journal.

Dr. Shoshana Herzig
“Our prescribing patterns in the setting of acute pain meaningfully impact downstream outcomes and prescribing practices,” said Shoshana J. Herzig, MD, MPH, director of hospital medicine research at Beth Israel Deaconess Medical Center, assistant professor of medicine at Harvard Medical School, and lead author on the consensus statement. “The degree of importance related to this topic often is underestimated by hospitalists because we think of it as a more straightforward situation – prescribing for acute pain. In reality, there are nuances to it, and we have data to show that it’s not done well a lot of the time.”

SHM convened a working group to develop the consensus statement, intended for clinicians practicing in the inpatient setting. The development of the statement began with the working group conducting a systemic review of relevant guidelines and composing a draft based on extracted recommendations. The working group then obtained feedback from external experts in hospital-based opioid prescribing, SHM members, the SHM Patient-Family Advisory Council, other professional societies and peer reviewers.

The statement reads, “Despite a paucity of data on the comparative effectiveness of different management strategies for acute pain, several areas of expert consensus emerged across existing guidelines, which were felt to be relevant and applicable to the hospital setting. The objective of these recommendations is to provide information that can be used to inform and support opioid-related management decisions for acute pain by clinicians practicing medicine in the inpatient setting.”

“The journal is always pleased to be able to publish results of rigorous and innovative work, and the consensus document authored by Dr. Herzig and her team represents an outstanding example,” said Andrew Auerbach, MD, MPH, MHM, Professor of Medicine in Residence at the University of California, San Francisco, and editor in chief for the Journal of Hospital Medicine. “As we enter the ‘post-opioid’ era of pain management, papers like these will provide critical guidance for how to improve pain control among hospitalized patients; they are important first steps in the transition to new pain care strategies that are safer, more effective and patient-centered.”

Study: Type 2 narcolepsy is significantly different from type 1

Article Type
Changed

Patients with type 1 narcolepsy have more clinical impairments and distinct functional abnormalities than do patients with type 2 narcolepsy, according to investigators.

Patients with type 2 “do not present with such severe handicaps and are clinically closer to hypersomniac patients than the patients with type 1 narcolepsy,” reported Yu-Shu Huang, MD, of Chang Gung Memorial Hospital and Chang Gung University, Taoyuan City, Taiwan, and associates. The study was published in Neurology.

The researchers used brain scans, neuropsychological tests, and other screening tests to analyze three groups of subjects – 104 patients with Na-1, 29 with Na-2, and a control group of 26 subjects. Depending on the group, 62%-66% of the subjects were men, and the mean age ranged from 19 to 20.

The mean age of onset for the narcolepsy groups was 12-13. Those with Na-1 had higher mean body mass indexes – 27 kg/m2 vs. 24 (Na-2) vs. 20 (control), (P = .001).

The patients in both narcolepsy groups showed similar levels of sleepiness, but those with Na-2 had significantly fewer abnormal findings and disturbances.

Patients with Na-2 had significantly fewer sleep-onset REM periods, longer mean sleep latencies, and lower apnea-hypopnea indexes. The human leukocyte antigen DQ-Beta1*0602 was also found less frequently in Na-2 compared to Na-1 (52% vs. 97%, respectively, P less than .001).

PET findings also revealed less impairment in Na-2 compared to Na-1. The researchers noted increased metabolic rate in several brain areas in Na-1, although hypometabolism is more common in some areas in Na-2.

 

 


Based on their findings, the authors challenge a previous study of insurance data that suggests patients with both types have similarly poor outcomes over the long term. (PLoS One 2012;7:e33525.)

“In our study,” the authors wrote, “compared to patients with type 2 narcolepsy, patients with type 1 narcolepsy present with much more severe handicaps as early as adolescence. Further studies are needed to clarify the issue.”

The Taiwan Ministry of Science and Technology funded the study. The authors report no relevant disclosures.
