Abstract

Abstract : BACKGROUND: Extended-release (ER) opioids are indicated for the management of persistent moderate to severe pain in patients requiring around-the-clock opioid analgesics for an extended period of time. Concerns have been raised regarding safety of ER opioids due to its potential for abuse and dependence. However, little is known about perioperative prescribing practices of ER opioids. This study assessed perioperative prescribing practices of ER opioids in noncancer surgical patients stratified by type of opioid exposure prior to admission and examined predictors of postoperative opioid administration in oral morphine equivalents (OME). METHODS: This was a retrospective cohort study using the University of California San Francisco Medical Center electronic health record data. This study included 25, 396 adult noncancer patients undergoing elective surgery under general anesthesia in the period 2015–2018. The primary study outcome was predictors of postoperative administration of opioids in hospitalized surgical patients. Secondary outcomes included patients discontinued and initiated on ER opioids during their hospital stay. RESULTS: substance use disorder diagnosis and use of opioids, surgery type, and postoperative administration of nonopioid analgesics were associated with postoperative administration of opioids ( P < .0001). The estimated adjusted mean (95% confidence interval [CI]) of postoperative administration of OME prior to admission in ER opioid users (170.08 mg; 147.08–196.67) was twice the amount for opioid-naïve patients (81.36 mg; 70.7–93.63; P < .0001). One in 5 prior to admission ER opioid users were weaned off ER opioids while hospitalized without adversely affecting their postoperative pain or hospital length of stay (LOS). Four of 5 patients who used ER opioids prior to admission also received ER opioids after surgery, whereas, 1 in 100 opioid-naïve patients received ER opioids during their hospital stay. CONCLUSIONS: We found significant variability in the perioperative prescribing practices of ER opioids in hospitalized noncancer surgical patients by use of opioids prior to admission and surgery type. Pain medicine practitioners and surgeons may play a significant role tackling the surgery-related risk of exposure to ER opioids and decreasing opioid-related complications.
