Purpose: Surgery is a major risk factor for chronic opioid use among patients who had not recently been prescribed opioids. This study identifies the rate of, and risk factors for, persistent opioid use following laparoscopic cholecystectomy and open inguinal hernia repair in patients not recently prescribed opioids. Methods: This retrospective population-based cohort study included all patients who had not been prescribed opioids in the 6 months prior to undergoing open inguinal hernia repair or laparoscopic cholecystectomy from January 2013 to July 2016 in Ontario. Opioid prescription was identified from the provincial Narcotics Monitoring System and data were obtained from the Institute for Clinical Evaluative Sciences. The primary outcome was persistent opioid use after surgery (3, 6, 9 and 12 months). Associated risk factors and prescribing patterns were also examined. Results: Among the 90,326 patients in the study cohort, 80% filled an opioid prescription after surgery, with 11%, 9%, 5% and 1% filling a prescription at 3, 6, 9 and 12 months, respectively. Significant variability was identified in the type of opioid prescribed (41% codeine, 31% oxycodone, 18% tramadol) and in regional prescribing patterns (mean prescription/region range, 135–225 oral morphine equivalents). Predictors of continued opioid use included age, female gender, lower income quintile and being operated on by less experienced surgeons. Conclusion: Most patients who undergo elective cholecystectomy and hernia repair will fill a prescription for an opioid after surgery, and many will continue to fill opioid prescriptions for considerably longer than clinically anticipated. There is important variability in opioid type, regional prescribing patterns and risk factors that identify strategic targets to reduce the opioid burden in this patient population.

Background: There has been a dramatic rise in opioid abuse, and diversion of excess, unused prescriptions is a major contributor. We assess the impact of implementing a new standardized pain care bundle to reduce postoperative opioids in outpatient general surgical procedures.Study Design: This study was designed to demonstrate non-inferiority for the primary end point: patient-reported average pain in the first 7 postoperative days. We prospectively evaluated 224 patients who underwent laparoscopic cholecystectomy or open hernia repair (inguinal, umbilical) pre-intervention to 192 patients post-intervention. We implemented a multimodal intra- and postoperative analgesic bundle, including promoting co-analgesia, opioid-reduced prescriptions, and patient education designed to clarify patient expectations. Patients completed a brief pain inventory at their first postoperative visit. Groups were compared using chi-square test, Mann-Whitney U test, and independent samples t-test, where appropriate.Results: No difference was seen in average postoperative pain scores in the pre- vs post-intervention groups (2.3 vs 2.1 of 10; p = 0.12). The reported quality of pain control improved post-intervention (good/very good pain control in 69% vs 85%; p < 0.001). The median total morphine equivalents for prescriptions filled in the post-intervention group were significantly less (100; interquartile range 75 to 116 pre-intervention vs 50; interquartile range 50 to 50 post-intervention; p < 0.001). Only 78 of 172 (45%) patients filled their opioid prescription in the post-intervention group (p < 0.001), with no significant difference in prescription renewals (3.5% pre-intervention vs 2.6% post-intervention; p = 0.62).Conclusions: For outpatient open hernia repair and cholecystectomy, a standardized pain care bundle decreased opioid prescribing significantly and frequently eliminated opioid use, and adequately treating postoperative pain and improving patient satisfaction.
