Chronic Opioid Use Independently Increases Complications and Resource Utilization After Primary Total Joint Arthroplasty

Abstract

BackgroundCurrent literature suggests a link between the chronic use of opioids and musculoskeletal surgical complications. Given the current opioid epidemic, the need to elucidate the effects of chronic opioid use (OD) on patient outcomes and cost has become important. The purpose of this study was to determine if OD is an independent risk factor for inpatient postoperative complications and resource utilization after primary total joint arthroplasty. MethodsA total of 3,545,565 patients undergoing elective, unilateral, primary total hip (THA) and knee (TKA) arthroplasty for osteoarthritis from January 2016 to December 2019 were identified using a large national database. In-hospital postoperative complications, length of stay, and total costs adjusted for inflation in opioid + patients were compared with patients without chronic opioid use (OD). Logistic regression analyses were used to control for cofounding factors. ResultsOD patients undergoing either THA or TKA had a higher risk of postoperative complications including respiratory (odds ratio (OR): 1.4 and OR: 1.3), gastrointestinal (OR: 1.8 and OR: 1.8), urinary tract infection (OR: 1.1 and OR: 1.2), blood transfusion (OR: 1.5 and OR: 1.4), and deep vein thrombosis (OR: 1.7 and OR: 1.6), respectively. Total cost ($16,619 ± $9,251 versus $15,603 ± $9,181, P < .001), lengths of stay (2.15 ± 1.37 versus 2.03 ± 1.23, P < .001), and the likelihood for discharge to a rehabilitation facility (17.8 versus 15.7%, P < .001) were higher in patients with OD. ConclusionOD was associated with higher risk for in-hospital postoperative complications and cost after primary THA and TKA. Further studies to find strategies to mitigate the impact of opioid use on complications are required.
