Opioid prescribing trends in a Veterans Affairs emergency department and dental clinic before and after implementation of opioid-prescribing guidelines

INTRODUCTION: Opioid overdose is highly prevalent among veterans. The Opioid Safety Initiative (OSI) and Centers for Disease Control and Prevention (CDC) issued prescribing guidelines for managing chronic pain. The purpose of this study was to investigate the impact of the 2013 OSI and 2016 CDC guidelines on opioid-prescribing trends in the emergency department and dental clinic within the Veterans Affairs Salt Lake City Health Care System. METHODS: In this retrospective, cohort study, opioid prescriptions were queried from January 1, 2013, through March 31, 2017, and separated into 3 groups: pre-OSI, post-OSI, and post-CDC. The primary outcome was to determine a decrease in opioid prescribing. Secondary outcomes included changes in concurrent benzodiazepine and naloxone prescriptions and prescriber status. Analysis of variance was used to determine a difference between study periods. RESULTS: There were 7339 opioid prescriptions identified. A statistically significant difference was found between the 3 groups in average number of opioids prescribed, morphine milligram equivalents per prescription, days' supplied, and medication quantity per prescription (P < .01). There was no significant difference between the 3 groups regarding morphine milligram equivalents per day (P = .24). Benzodiazepine prescribing remained the same. Concurrent naloxone prescriptions increased. DISCUSSION: The results demonstrate that days' supply, quantity, and morphine milligram equivalent per day in the post-CDC group were consistent with guideline recommendations. Concurrent naloxone prescribing increased throughout all time periods. Implementation of guidelines impacted opioid-prescribing trends, ultimately lessening potential for misuse and abuse. However, there is still need for improvement with reducing concurrent benzodiazepine prescriptions.
