Continuation of Opioid Therapy at Transitions of Care in Critically Ill Patients.

PURPOSE: Opioids are one of the high-risk medication classes that are administered to critically ill patients during their intensive care unit (ICU) stay. However, little attention has been given to inpatient opioid prescribing practices, especially in critically ill patients. The purpose of our study was to characterize opioid prescribing practices across 2 transitions of care during an inpatient hospital stay: medical ICU (MICU)/intermediate care unit (IMC) to floor and floor to hospital discharge and identify potential patient-specific factors that impact opioid continuation. METHODS: This is a retrospective cohort study evaluating opioid-naive adult patients with new opioid therapy initiated in MICU/IMC at a tertiary care academic medical center from December 1, 2016, to November 30, 2017. Opioid continuation rate was assessed twice: transition 1 (MICU/IMC to floor) and transition 2 (floor to hospital discharge). RESULTS: In total, 112 opioid-naive patients with initial opioid administration in the MICU/IMC were included. Opioid therapy was continued in 56.1% (37/66) at transition 1 and 56.8% of patients (21/37) at transition 2. Patients with opioids continued at transition 1 had a longer hospital length of stay compared to those not continued on opioids, 22 (interquartile range [IQR] 11-36) vs 8 (IQR 6-14; P = .0004). Among the patients continued on opioids at hospital discharge, intubation during hospital stay and cumulative opioid dosage were greater than those not continued on opioids (17 [80.9%] vs 7 [43.8%], P = .019; and 3482 mcg [IQR 1690-9530] vs 732.5 mcg [IQR 187.5-1360.9], P = .0018, respectively). CONCLUSIONS: Opioid-naive patients receiving opioid therapy in the MICU/IMC had a continuation rate of >56% during transitions of care, including hospital discharge. Factors that contributed to the continuation of opioids at transitions of care included longer hospital length of stay, intubation, and cumulative hospital opioid dosage. These findings may help to provide health systems with guidance on targeted opioid stewardship programs.

Impact of an Antipsychotic Discontinuation Bundle During Transitions of Care in Critically Ill Patients.

INTRODUCTION:: Delirium affects a large proportion of patients admitted to the intensive care unit (ICU) and is associated with increased morbidity and mortality. Antipsychotics have become frequently used agents for the treatment of delirium; however, they are often continued at transitions of care. This has potential negative short- and long-term health consequences that are preventable. We investigated the antipsychotic tapering bundle's impact on the rate of antipsychotic continuation at transitions from the medical intensive care unit (MICU). METHODS:: This was a preretrospective and postretrospective chart review that included adult patients in the MICU initiated on antipsychotic therapy for ICU delirium. A bundled multidisciplinary education program and antipsychotic discontinuation algorithm were implemented in the MICU to provide recommendations for safe and effective use of antipsychotics for ICU delirium and minimize continuation of therapy at transitions of care. Rates of antipsychotic continuation at transition from the MICU were compared between the preintervention and postintervention groups with the χ2 test. RESULTS:: A total of 140 patients in the prebundle group and 141 patients in the postbundle group were enrolled. Overall, baseline characteristics were similar. After implementation of the discontinuation bundle, antipsychotic continuation at MICU discharge decreased (27.9% in the prebundle group vs 17.7% in the postbundle group; P < .05). In the multivariate analysis, patients were less likely to be continued on antipsychotic therapy at MICU discharge after implementation of the bundle (odds ratio [OR]: 0.47; 95% confidence interval [CI]: 0.26-0.86). There were also lower rates of overall antipsychotic continuation at hospital discharge (OR: 0.4; 95% CI: 0.18-0.89). CONCLUSION:: This is the first study to demonstrate a reduction in antipsychotic continuation at transition from the MICU after implementation of an antipsychotic discontinuation bundle in ICU patients. We believe this bundle allows for safer transitions of care from the MICU and decreases unnecessary antipsychotic therapy.

Risk of venous thromboembolism in patients with chronic liver disease and the utility of venous thromboembolism prophylaxis.

OBJECTIVE: To review the current literature on the risk of venous thromboembolism (VTE) in patients with chronic liver disease (CLD). DATA SOURCES: Literature was accessed through MEDLINE/PubMed (1996-December 2011) using the search terms liver disease, cirrhosis, venous thromboembolism, deep vein thrombosis, and pulmonary embolism. STUDY SELECTION AND DATA EXTRACTION: Relevant observational and population-based studies were included to present background information. Bibliographies of all relevant articles were reviewed for additional citations. DATA SYNTHESIS: Liver disease affects the synthesis of procoagulants and anticoagulants, resulting in hemostatic alterations and abnormal laboratory values. Retrospective studies characterized the VTE incidence to be 0.5-6.3%. Population-based studies reported VTE relative risks of 1.74-2.10 in patients with CLD compared with population controls and VTE odds ratios of 0.9-1.39 for hospitalized patients with CLD compared with controls without liver disease. There is a paucity of data on the use of pharmacologic prophylaxis in patients with CLD. CONCLUSIONS: Patients with CLD should be assessed for VTE risk and given VTE prophylaxis when the benefits outweigh the risks. Diagnoses of CLD or elevated international normalized ratio do not confer protection against development of VTE and do not justify withholding pharmacologic prophylaxis based on this diagnosis.

Personality: A potentially untapped resource in the selection of postgraduate pharmacy residents.

PURPOSE: This study assessed whether personality testing of postgraduate year 1 (PGY1) pharmacy residency applicants was feasible and predicted important selection outcomes, including interview offers. METHODS: Applicants to the PGY1 pharmacy residency program at a large academic medical center were invited to complete a 50-item online personality test based on the 5-factor model (ie, the "Big Five"). Scores were sealed until after matching, at which point they were compared to screening, interview, and ranking and match outcomes. Endpoints of interest included the feasibility of the test (eg, time required for completion, completion rate) and whether personality predicted the odds of an interview offer. RESULTS: The personality test was taken by 137 PGY1 applicants (69.5%) and required a median of 6.8 minutes to complete. Openness to experience was associated with decreased odds of an interview offer (adjusted odds ratio [OR], 0.86; 95% confidence interval [CI], 0.75-0.98), whereas conscientiousness and extraversion were associated with increased odds of an interview offer (conscientiousness: adjusted OR, 1.26; 95% CI, 1.02-1.55; extraversion: OR, 1.16; 95% CI, 1.03-1.31). When combined with traditional screening criteria (eg, awards, leadership positions), openness to experience and extraversion remained predictors of an interview offer (in the directions specified above), whereas conscientiousness did not. In an exploratory analysis of interviewees, agreeableness was a negative predictor of interview score. Personality did not predict screening scores or final ranking. CONCLUSION: Personality testing, based on the traits desired at individual residency programs, could be a valuable addition to the methods used for selecting PGY1 pharmacy residents.

Vancomycin Pharmacokinetics in Obese Patients with Sepsis or Septic Shock.

STUDY OBJECTIVES: Obese patients with sepsis or septic shock may have altered vancomycin pharmacokinetics compared with the general population that may result in improper dosing or inadequate drug concentrations. The objective of this study was to characterize vancomycin pharmacokinetics in obese patients with sepsis or septic shock, and to develop a novel pharmacokinetic dosing model based on pharmacokinetic-pharmacodynamic target requirements. DESIGN: Prospective observational pharmacokinetic study. SETTING: Large quaternary academic medical center. PATIENTS: Sixteen obese (body mass index [BMI] 30 kg/m2 or higher) adults with sepsis and either a gram-positive bacteremia or requiring vasopressor support (septic shock), who were receiving vancomycin between November 2016 and June 2018, were included. Patients were excluded if they were receiving renal replacement therapy or extracorporeal membrane oxygenation, treatment for central nervous system infections, pregnant, or receiving vancomycin for surgical prophylaxis. INTERVENTION: Four blood samples per patient were collected following a single dose of vancomycin: one peak serum vancomycin level (within 1-2 hrs of infusion completion), two random levels during the dosing interval, and one trough level (within 30-60 min of the next dose) were measured. MEASUREMENTS AND MAIN RESULTS: A population pharmacokinetic model was developed to describe vancomycin concentrations over time. Simulations to determine optimal dosing were performed using the pharmacokinetic model with different ranges of creatinine clearance (Clcr ) and different vancomycin daily doses. Median age of the patients was 62 years; median BMI was 36.1 kg/m2 , Acute Physiology and Chronic Health Evaluation II score was 26, and Sequential Organ Failure Assessment score was 11. Eleven patients (69%) had an acute kidney injury. Median initial vancomycin dose was 15 mg/kg; median vancomycin trough concentration was 17 mg/L. A one-compartment model best characterized the pharmacokinetics of vancomycin in obese patients with sepsis or septic shock. Volume of distribution was slightly increased in this population (0.8 L/kg) compared with the general population (0.7 L/kg). Only Clcr effect on drug clearance was found to be significant (decrease in the objective function value by 16.4 points), confirming that it is a strong predictor of vancomycin clearance. CONCLUSION: To our knowledge, this study provides the first population-based pharmacokinetic model in obese patients with sepsis or septic shock. The nomograms generated from this pharmacokinetic model provide a simplified approach to vancomycin dosing in this patient population.

Topiramate for binge-eating disorder associated with obesity.

OBJECTIVE: To review the use of topiramate for the treatment of binge-eating disorder (BED) associated with obesity. DATA SOURCES: MEDLINE (1966-July 2006) and the Cochrane Database (2006, issue 3) were used to conduct an English-language literature search. Key search terms included eating disorder, binge-eating, and topiramate. Bibliographies of identified articles were examined for additional references. DATA SYNTHESIS: BED is characterized by excessive food intake with lack of control during eating episodes, but without subsequent compensatory weight loss mechanisms, and is often associated with obesity and psychiatric disorders. Evidence suggests that topiramate may have mood-stabilizing properties and cause decreased appetite and weight. One case series, 1 case report, 2 open-label studies, and 1 placebo-controlled trial have described the use of topiramate for BED associated with obesity. Doses ranging from 50 to 1400 mg/day were stated to be effective in these reports. Adverse reactions included paresthesias, cognitive impairment, somnolence, and gastrointestinal distress. Although these adverse effects were transient, they may interfere with patients' tolerability of topiramate therapy. CONCLUSIONS: Albeit limited, evidence suggests that topiramate may be a viable short- and long-term treatment alternative for BED associated with obesity for patients with limited options. Further controlled trials are necessary to establish topiramate's place in therapy, optimal dosing, and length of treatment for this eating disorder.

Hospital delirium treatment: Continuation of antipsychotic therapy from the intensive care unit to discharge.

PURPOSE: The rate of continuation of antipsychotics for the management of delirium during hospital transitions of care in a tertiary care medical center was investigated. METHODS: A retrospective chart review was conducted for adult patients admitted to the medical intensive care unit (MICU) between June 1, 2011, and May 31, 2012, who were initiated on antipsychotic therapy at least 24 hours before transfer out of the MICU. The primary outcome evaluated was the percentage of patients initiated on an antipsychotic in the MICU who were continued on therapy after transfer to a medical ward. Secondary outcomes included the appropriateness of continuing antipsychotic therapy during transitions of care and the percentage of patients continued on an antipsychotic after hospital discharge. RESULTS: Of the 87 patients who met the study inclusion criteria, 23 (26%) were continued on antipsychotic therapy after their transfer from the MICU to the medical ward. Of the 23 patients continued on antipsychotic therapy, 9 (39%) were discharged from the hospital with an antipsychotic. Fourteen of the 23 patients were eligible for assessment of inappropriate antipsychotic continuation upon transfer from the MICU. Of these 14 patients, 9 (64%) were inappropriately continued on an antipsychotic. Patients continued on antipsychotic therapy at hospital discharge were more likely to be discharged to a facility (rehabilitation, skilled nursing facility, or healthcare institution) (p = 0.049).Future areas for study should include (1) prospective analysis to understand the clinical decision-making of providers when treating delirium, (2) evaluation of the long-term impact of continuing antipsychotic therapy for delirium, and (3) ways to improve communication of medication regimens during transitions of care. Plans to reduce antipsychotic continuation could involve reassessing patients on the medical wards, improving documentation of the indication for use in the medical record, or developing protocols to taper off antipsychotics before patients are discharged from the hospital. CONCLUSION: The continuation of antipsychotics for the management of delirium during transitions of care was a common practice at a tertiary care medical center. Patients receiving antipsychotics for treatment of delirium in the MICU were inappropriately continued on these agents when transferred from the MICU to the medical floor or discharged from the hospital.
