ABSTRACT
BACKGROUND: No previous literature has compared methadone with oxycodone for intravenous (IV) opioid weaning. OBJECTIVE: To determine if a weaning strategy using enteral methadone or oxycodone results in faster time to IV opioid discontinuation. METHODS: This was a single-center, retrospective, cohort medical record review of mechanically ventilated adults in an intensive care unit (ICU) who received a continuous IV infusion of fentanyl or hydromorphone for ≥72 hours and an enteral weaning strategy using either methadone or oxycodone from January 1, 2020, through December 31, 2021. Differences between groups were controlled for using Cox proportional hazards models. The primary outcome was time to continuous IV opioid discontinuation from the initiation of enteral opioids. Secondary outcomes included the primary endpoint stratified for COVID-19, duration of mechanical ventilation, ICU and hospital length of stay, and safety measures. RESULTS: Ninety-three patients were included, with 36 (38.7%) patients receiving methadone and 57 (61.3%) receiving oxycodone. Patients weaned using methadone received IV opioids significantly longer before the start of weaning (P = 0.04). However, those on methadone had a significantly faster time to discontinuation of IV opioids than those on oxycodone, mean (standard deviation) 104.7 (79.4) versus 158.3 hours (171.2), P = 0.04, and, at any time, were 1.89 times as likely to be weaned from IV opioids (hazard ratio, HR 1.89, 95% confidence interval, CI 1.16-3.07, P = 0.01). CONCLUSION AND RELEVANCE: This was the first study showing enteral methadone was associated with a shorter duration of IV opioids without differences in secondary outcomes compared with oxycodone. Prospective research is necessary to confirm this finding.
ABSTRACT
BACKGROUND AND PURPOSE: The American Society of Health-System Pharmacists (ASHP) postgraduate year 2 (PGY2) critical care pharmacy residency program offers an elective competency area, E3: Mass Casualty. Similar elective competencies are also available for PGY2 emergency medicine and postgraduate year 1/2 pharmacotherapy programs. Because of the COVID-19 pandemic, pharmacist proficiency in the management of disasters is even more urgent. However, few residency programs require or include a specific learning experience to achieve this competency. This article provides examples of opportunities that residency programs can implement to offer an Emergency Preparedness/Mass Casualty (EP/MC) learning experience. EDUCATIONAL ACTIVITY AND SETTING: A longitudinal EP/MC learning experience was integrated into a PGY2 critical care program. FINDINGS: A longitudinal EP/MC learning experience within the PGY2 critical care, emergency medicine, and pharmacotherapy residency program curricula is achievable and promotes resident development. Learning experience components included topic discussions, participation on local and state-level emergency preparedness (EP) committees, completion of certification programs, projects, and participation on statewide emergency response teams. SUMMARY: Implementation of a longitudinal EP/MC learning experience formalizes topics and activities that support achievement of the ASHP elective competency area of Mass Casualty for PGY2 residency programs. EP/MC goals and objectives should be a requirement for critical care, emergency medicine, pharmacotherapy, and health-system pharmacy administration and leadership PGY2 programs. By formalizing training, pharmacists can be better prepared for EP and more integrated into multidisciplinary disaster response teams.
