Implementation and Effectiveness of Opioid Prescribing Guidelines After Hiatal Hernia Repair.

INTRODUCTION: We defined institutional opioid prescribing patterns, established prescribing guidelines, and evaluated the adherence to and effectiveness of these guidelines in association with opioid prescribing after hiatal hernia repair (HHR). METHODS: A retrospective chart review was completed for patients who underwent transthoracic (open) or laparoscopic HHR between January and December 2016. Patient-reported opioid use after surgery was used to establish prescribing recommendations. Guideline efficacy was then evaluated among patients undergoing HHR after implementation (August 2018 to June 2019). Data are reported in oral morphine equivalents (OMEs). RESULTS: The initial cohort included n = 87 patients (35 open; 52 laparoscopic) with a 68% survey response rate. For open repair, median prescription size was 338 mg OME (interquartile range [IQR] 250-420) with patient-reported use of 215 mg OME (IQR 78-308) (P = 0.002). Similarly, median prescription size was 270 mg OME (IQR 200-319) with patient-reported use of 100 mg OME (IQR 4-239) (P < 0.001) for laparoscopic repair. Opioid prescribing guidelines were defined as the 66th percentile of patient-reported opioid use. Postguideline implementation cohort included n = 108 patients (36 open; 72 laparoscopic). Median prescription amount decreased by 54% for open and 43% laparoscopic repair, with no detectable change in the overall refill rate after guideline implementation. Patient education, opioid storage, and disposal practices were also characterized. CONCLUSIONS: Evidence-based opioid prescribing guidelines can be successfully implemented for open and laparoscopic HHR with a high rate of compliance and without an associated increase in opioid refills.
