Abstract
IntroductionThis study assesses the association of preoperative use of gabapentinoids (GBPs) with postoperative risk of opioid-related disorders in peripheral artery disease patients undergoing lower extremity bypass operation. MethodsThis is a retrospective propensity score-matched analysis of patients undergoing peripheral artery bypass in TriNetX, a multicenter national database. Two study groups were constituted based on the preoperative history of prescribed GBPs. Primary outcomes were opioid-related disorders and mortality. The outcomes were reported at two-time endpoints that is, at 1 and 5 y. ResultsThis study population included a total of 23,706 patients. After propensity score-matched analysis, each group contained 5130 patients. The primary outcomes showed a significant increase in postoperative opioid-related disorders at the 1 and 5-y time points between GBPs and no GBPs groups: 1-y outcome (2.0% versus 1.1%; adj. P = 0.007) and 5-y outcome (4.5% versus 3.5%; adj. P = 0.035). Logistic regression analysis revealed an increase in the 1-y (adjusted odds ratio= 1.664; 95% CI [1.217, 2.273], P = 0.001) and 5-y (OR = 1.353; 95% CI [1.107, 1.653], P = 0.003) odds of opioid-related disorders in patients on GBPs. A secondary analysis showed a significant dose-dependent increase in the associated risk of 5-y opioid-related disorders in patients with a history of prescribed gabapentin. ConclusionsIn patients undergoing lower extremity bypass with a history of gabapentin use, there is an associated increased long-term risk of opioid-related disorders in a dose-dependent fashion. Overall, this study highlights weighing risks and benefits of prescribing GBPs for pain control versus their long-term associated risk of opioid-related disorders among other adverse outcomes.
