ObjectiveTo determine the association between PPOU and the long-term risk of OUD and opioid overdose.Summary Background DataPPOU is a commonly used outcome in the surgical literature; its incidence and risk factors have been well described. However, its association to long term outcomes, including OUD and opioid overdose, is unknown.MethodsA retrospective cohort study utilizing the Veterans Health Administration corporate data warehouse. Patients undergoing any surgery between January 1, 2008 and December 31, 2018 were included and followed until December 31, 2020. Univariate and multivariate survival analysis were used to determine the association between PPOU and OUD and overdose. Sensitivity analyses were conducted to determine the impact of different definitions of persistent opioid use and the effect of preoperative opioid use.ResultsA total of 344,745 patients undergoing surgery were included and followed for a median of 6.18 years (IQR 3.53-9.12). PPOU was associated with an increased hazard of developing both OUD (HR = 1.88, CI: 1.81-1.95, P < 0.001) and overdose (HR = 1.83, CI: 1.72-1.94, P < 0.001). This association remained consistent after adjustment for comorbidities and across all sensitivity analyses.ConclusionsSurgical patients who develop PPOU are at increased risk of both OUD and overdose as compared to surgical patients who do not develop persistent use.Copyright © 2021 Wolters Kluwer Health, Inc.
