Hospital opioid use predicts the need for discharge opioid prescriptions following laparoscopic bariatric surgery
Diaz SE, Dandalides AM, and Carlin AM. Hospital opioid use predicts the need for discharge opioid prescriptions following laparoscopic bariatric surgery. Surg Endosc 2022.
BACKGROUND: Overprescribing of opioids after surgery increases new persistent opioid use and diversion contributing to the opioid epidemic. There is a paucity of evidence regarding discharge opioid prescribing after bariatric surgery.
METHODS: We conducted a retrospective, cohort study analyzing post-operative opioid use at a single institution in patients who underwent laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LGB) from July 2019 thru February 2020. Multimodal analgesia was used including 5 mg oxycodone pills as needed during hospitalization with five prescribed on discharge if requested after discussion. Opioid use was determined from medical record review and post-operative data collected from patients at a 2-week follow-up visit. The Michigan Automated Prescription System (MAPS) was used as an adjunct to evaluate perioperative opioid prescriptions.
RESULTS: The cohort of 84 patients included those having LSG (72) and LGB (12). Fifty-five patients (65%) received a prescription for opioids on discharge and 91% filled their prescription. Only 44% (22/50) of those filling their opioid prescription took any opioids with 24% (65/275) of the total pills prescribed actually consumed. Opioid use on the surgical ward had the strongest correlation with discharge opioid use (rho = 0.65, CI 0.494, 0.770). The number of opioid pills taken on the surgical ward was positively associated with the number of pills taken after discharge. Those who took none, 1 to 3, or 4 or more opioid pills consumed 0.14 ± 0.48, 0.95 ± 1.71, and 3.14 ± 1.86 pills after discharge (p < 0.001). No patients required an additional opioid prescription within 90 days of surgery with MAPS confirmation.
CONCLUSION: Postoperative in-hospital opioid use following laparoscopic bariatric surgery predicts opioid use after discharge. This knowledge can guide patient-specific discharge opioid prescribing with the potential to mitigate diversion and reduce chronic opioid use.
