RESUMEN
PURPOSE: Results of a study to determine the effect of a pharmacist-led opioid task force on emergency department (ED) opioid use and discharge prescriptions are presented. METHODS: An observational evaluation was conducted at a large tertiary care center (ED volume of 115,000 visits per year) to evaluate selected opioid use outcomes before and after implementation of an ED opioid reduction program by interdisciplinary task force of pharmacists, physicians, and nurses. Volumes of ED opioid orders and discharge prescriptions were evaluated over the entire 25-month study period and during designated 1-month preimplementation and postimplementation periods (January 2017 and January 2018). Opioid order trends were evaluated using linear regression analysis and further investigated with an interrupted time series analysis to determine the immediate and sustained effects of the program. RESULTS: From January 2017 to January 2018, ED opioid orders were reduced by 63.5% and discharge prescriptions by 55.8% from preimplementation levels: from 246.8 to 90.1 orders and from 85.3 to 37.7 prescriptions per 1,000 patient visits, respectively. Over the entire study period, there were significant decreases in both opioid orders (ß, -78.4; 95% confidence interval [CI], -88.0 to -68.9; R2, 0.93; p < 0.0001) and ED discharge prescriptions (ß, -24.4; 95% CI, -27.9 to -20.9; R2, 0.90; p < 0.001). The efforts of the task force had an immediate effect on opioid prescribing practices; results for effect sustainability were mixed. CONCLUSION: A clinical pharmacist-led opioid reduction program in the ED was demonstrated to have positive results, with a more than 50% reduction in both ED opioid orders and discharge prescriptions.
