Pathway-driven, post-pancreatectomy opioid reduction interventions have proven effective and sustainable and may have a "halo effect" on other major abdominal cancer operations. This study's aim was to analyze the sequential effects of expanding opioid reduction efforts from pancreatectomy on opioids prescribed after hepatectomy. This is a retrospective cohort study utilizing data from the electronic health record and a prospective quality improvement database for consecutive hepatectomy patients (09/2016-02/2024). Cohorts were based on 5 distinct eras (E) of opioid-related protocol updates (E1/pre-intervention historical baseline: 09/2016-03/2017, E2/introduction of 5x-multiplier: 04/2017-09/2018, E3/departmental opioid education program: 10/2018-12/2019, E4/initial post-hepatectomy pathways: 01/2020-06/2022, E5/updated pancreatectomy pathways influencing hepatectomy care: 07/2022-02/2024). Of 2005 patients, 31% underwent major hepatectomy, 14% intermediate, 46% minor, and 9% combination surgery/other. Most (79%) were performed via open approach. Median hospital stay decreased from 5 to 4 days between E1-E5. Both intraoperative (E1:80mg, E5:37mg; p<0.001) and total inpatient (E1:181mg, E5:86mg; p<0.001) median oral morphine equivalents (OME) were reduced >50%. A 73% reduction in discharge OME was observed between E1 (225mg) and E5 (60mg; p<0.001), with clinically similar median pain scores at discharge (score 1-2 of 10). Concurrent universal adoption of routine 3-drug non-opioid discharge prescriptions (E1:70%, E5:98%) correlated with proportion of patients discharged opioid-free (E1:8%, E5:43%; p<0.001). Directed opioid reduction efforts for pancreatectomy influenced clinically meaningful post-hepatectomy reductions in inpatient and discharge opioid volumes. A "halo effect" of intradepartmental opioid reduction efforts is attainable and corresponds to measurable increases in opioid-free or nearly opioid-free discharges after major abdominal cancer surgery.
