An electronic alert to decrease Kayexalate ordering.

Important safety concerns have recently emerged regarding the use of sodium polystyrene sulfonate (Kayexalate), a cation-exchange resin commonly used for the treatment of hyperkalemia. We implemented an electronic alert system at a tertiary care academic medical center to warn providers of the safety concerns of Kayexalate. We assessed the number of Kayexalate prescriptions per month, as well as the number of grams of Kayexalate ordered per month, one year before versus one year after implementing the alert. The mean (±SD) number of Kayexalate orders decreased from 123 (±12) to 76 (±14) orders/month (38% absolute reduction, p < 0.001) after implementing the alert. Additionally, the mean (±SD) amount of Kayexalate prescribed decreased from 3332 (±329) to 1885 (±358) g/month (43% absolute reduction, p < 0.001). We conclude that an electronic alert is an effective tool to decrease Kayexalate ordering.

Well-Being in Graduate Medical Education: A Call for Action.

Job burnout is highly prevalent in graduate medical trainees. Numerous demands and stressors drive the development of burnout in this population, leading to significant and potentially tragic consequences, not only for trainees but also for the patients and communities they serve. The literature on interventions to reduce resident burnout is limited but suggests that both individual- and system-level approaches are effective. Work hours limitations and mindfulness training are each likely to have modest benefit. Despite concerns that physician trainee wellness programs might be costly, attention to physician wellness may lead to important benefits such as greater patient satisfaction, long-term physician satisfaction, and increased physician productivity. A collaborative of medical educators, academic leaders, and researchers recently formed with the goal of improving trainee well-being and mitigating burnout. Its first task is outlining this framework of initial recommendations in a call to action. These recommendations are made at the national, hospital, program, and nonwork levels and are meant to inform stakeholders who have taken up the charge to address trainee well-being. Regulatory bodies and health care systems need to be accountable for the well-being of trainees under their supervision and drive an enforceable mandate to programs under their charge. Programs and individuals should develop and engage in a "menu" of wellness options to reach a variety of learners and standardize the effort to ameliorate burnout. The impact of these multilevel changes will promote a culture where trainees can learn in settings that will sustain them over the course of their careers.

Serum Osmolality and Postdischarge Outcomes After Hospitalization for Heart Failure.

Serum osmolality may fluctuate with neurohormonal activation and in response to certain therapeutics in patients with heart failure (HF). The clinical relevance of osmolality in patients with HF has not been defined. In this post hoc analysis of the Efficacy of Vasopressin Antagonism in Heart Failure: Outcome Study with Tolvaptan trial, we analyzed serum osmolality measured at discharge in 3,744 patients hospitalized for HF and reduced ejection fraction (EF ≤40%). Median follow-up was 9.9 months. The association between discharge osmolality and all-cause mortality (ACM) and composite cardiovascular mortality or HF hospitalization was nonlinear; and thus, patients were divided into low (≤284), normal (285 to 300), and high (≥300 mOsm/kg) osmolality. Median serum osmolality at discharge was 297 (290 to 304) mOsm/kg. Patients in the low osmolality group (n = 454,12.1%) were more likely to be younger, men, have lower rates of hypertension, coronary artery disease, chronic kidney disease, diabetes, and have lower serum sodium, creatinine, systolic blood pressure, and EF (all p <0.001). Low discharge osmolality was associated with higher ACM (low 29.3%; normal 23.6%; high 25.2%; p = 0.04) and the composite endpoint (low 45.6%; normal 39.3%; high 41.8%; p = 0.04). After risk adjustment, a 15 mOsm/kg decrease in osmolality was predictive of higher ACM (hazard ratio 1.61, 95% CI 1.19 to 2.17) and the composite endpoint (hazard ratio 1.37, 95% CI 1.06 to 1.75) in the low osmolality group. These associations were not seen in patients with normal or high osmolality. Interaction analyses for tolvaptan treatment were nonsignificant (p >0.4). In conclusion, low discharge serum osmolality was independently predictive of worse postdischarge mortality and readmission. Further study is required to clarify the clinical utility of serum osmolality in hospitalized patients with HF.

Acetaminophen-induced anion gap metabolic acidosis and 5-oxoprolinuria (pyroglutamic aciduria) acquired in hospital.

A rare cause of high anion gap acidosis is 5-oxoproline (pyroglutamic acid), an organic acid intermediate of the gamma-glutamyl cycle. Acetaminophen and several other drugs have been implicated in the development of transient 5-oxoprolinemia in adults. We report the case of a patient with lymphoma who was admitted for salvage chemotherapy. The patient subsequently developed fever and neutropenia and was administered 20.8 g of acetaminophen during 10 days. During this time, anion gap increased from 14 to 30 mEq/L (14 to 30 mmol/L) and altered mental status developed. After usual causes of high anion gap acidosis were ruled out, a screen for urine organic acids showed 5-oxoproline levels elevated at 58-fold greater than normal values. Predisposing factors in this case included renal dysfunction and sepsis. Clinicians need to be aware of this unusual cause of anion gap acidosis because it may be more common than expected, early discontinuation of the offending agent is therapeutic, and administration of N -acetylcysteine could be beneficial.

Promoting Success: A Professional Development Coaching Program for Interns in Medicine.

BACKGROUND: Residency is an intense period. Challenges, including burnout, arise as new physicians develop their professional identities. Residency programs provide remediation, but emotional support for interns is often limited. Professional development coaching of interns, regardless of their performance, has not been reported. OBJECTIVE: Design, implement, and evaluate a program to support intern professional development through positive psychology coaching. METHODS: We implemented a professional development coaching program in a large residency program. The program included curriculum development, coach-intern interactions, and evaluative metrics. A total of 72 internal medicine interns and 26 internal medicine faculty participated in the first year. Interns and coaches were expected to meet quarterly; expected time commitments per year were 9 hours (per individual coached) for coaches, 5 1/2 hours for each individual coachee, and 70 hours for the director of the coaching program. Coaches and interns were asked to complete 2 surveys in the first year and to participate in qualitative interviews. RESULTS: Eighty-two percent of interns met with their coaches 3 or more times. Coaches and their interns assessed the program in multiple dimensions (participation, program and professional activities, burnout, coping, and coach-intern communication). Most of the interns (94%) rated the coaching program as good or excellent, and 96% would recommend this program to other residency programs. The experience of burnout was lower in this cohort compared with a prior cohort. CONCLUSIONS: There is early evidence that a coaching program of interactions with faculty trained in positive psychology may advance intern development and partially address burnout.

The impact of duty hours restrictions on job burnout in internal medicine residents: a three-institution comparison study.

PURPOSE: Internal medicine (IM) residents commonly develop job burnout, which may lead to poor academic performance, depression, and medical errors. The extent to which duty hours restrictions (DHRs) can mitigate job burnout remains uncertain. The July 2011 DHRs created an opportunity to measure the impact of decreased work hours on developing burnout in IM residents. METHOD: A survey was administered twice to first-year IM residents at three academic medical centers between June 2011 and July 2012. To estimate the impact of the 2011 DHRs, data from this cohort, including demographics, sleepiness, hospital-based patient service characteristics, and burnout measures, were compared with data from 2008-2009 from first-year IM residents at the same institutions. RESULTS: Of eligible residents, 128/188 (68%) from the 2011-2012 cohort and 111/180 (62%) from the 2008-2009 cohort completed both surveys. Year-end burnout prevalence (92/123 [75%] versus 91/108 [84%], P = .08) and incidence (59/87 [68%] versus 55/68 [81%], P = .07) did not differ significantly between cohorts. There was no difference in year-end prevalence of excessive Epworth sleepiness (72/122 [59%] versus 71/108 [66%], P = .29) between cohorts; however, a greater percentage of residents who developed burnout in the 2011-2012 cohort reported caring for > 8 patients on their service (2011-2012 versus 2008-2009) (29/59 [49%] versus 5/34 [15%], P < .01). CONCLUSIONS: Job burnout and self-reported sleepiness in IM resident physicians were unchanged after the 2011 DHRs at three academic institutions. Further investigation into the determinants of burnout can inform effective interventions.

Enhanced creatinine and estimated glomerular filtration rate reporting to facilitate detection of acute kidney injury.

OBJECTIVES: While acute kidney injury (AKI) can be diagnosed based on specified increases in a patient's plasma creatinine level, standard creatinine reporting methods typically only flag creatinine results as abnormal when outside the reference range and often fail to identify rising creatinine values indicative of AKI. Here, we evaluate the impact of this limitation in standard creatinine reporting and develop and implement an enhanced creatinine reporting algorithm. METHODS: We evaluated 59,712 plasma creatinine results collected over approximately 3 months, using computational simulations and statistical analyses. RESULTS: Our analyses demonstrated that 29% of creatinine results substantially increased over the patient's baseline and concerning for AKI remained within the normal reference range. These concerning results would not be flagged as abnormal using standard reporting. Likewise, we found that simple delta checks are also insensitive at AKI detection. To improve creatinine reporting, we developed and implemented an algorithm within our laboratory information system to alert clinicians to rising creatinine results, which we describe in this report. CONCLUSION: While both creatinine reference limits and simple delta checks are insensitive for AKI identification, a simple algorithm can be implemented within a common laboratory information system to enhance AKI identification.
