Semaglutide Use Prior to Total Hip Arthroplasty Results in Fewer Postoperative Prosthetic Joint Infections and Readmissions

Background: Semaglutide, a novel diabetes management medication, is known for its efficacy in inducing weight loss. Despite this, its impact on outcomes after total hip arthroplasty (THA) remains unclear. The aim of this study was to evaluate if THA patients on semaglutide demonstrate: (1) fewer medical complications; (2) fewer implant -related complications; (3) fewer readmissions; and (4) lower costs. Methods: Using a national claims database from 2010 to 2021, we retrospectively examined diabetic patients prescribed semaglutide who underwent primary THA. This yielded 9,465 patients (Semaglutide = 1,653; Control = 7,812). Multivariable logistic regression was used to evaluate the following outcomes: 90 -day postoperative medical complications, 2 -year implant -related complications, 90 -day readmissions, in -hospital lengths of stay, and day -of -surgery and 90 -day episode of care costs. Results: Semaglutide users exhibited lower 90 -day readmission rates (6.2 versus 8.8%; odds ratio 0.68; P < .01) and reduced prosthetic joint infections (1.6 versus 2.9%; odds ratio 0.56; P < .01). However, medical complication rates, hospital stays, same -day surgical costs, and 90 -day episode costs showed no significant differences. Conclusions: This study highlights semaglutide users undergoing THA with fewer 90 -day readmissions and 2 -year prosthetic joint infections. Although no variance appeared in medical complications, hospital stays, or costs, the medication's notable glycemic control and weight loss benefits could prompt presurgery consideration. Further research is essential for a comprehensive understanding of semaglutide's impact on post-THA outcomes. (c) 2023 Elsevier Inc. All rights reserved.
