Preoperative Opioid Therapy Correlated With Increased Rate of Complications in Foot and Ankle Surgery.

Abstract

BackgroundThe purpose of this study is to determine whether patients with a history of preoperative opioid use will have an increased likelihood of postoperative opioid use and complications after undergoing forefoot, hindfoot, or ankle surgery.MethodsA retrospective review was conducted on forefoot, hindfoot, and ankle surgeries between 2015 and 2020 with a single fellowship-trained orthopaedic foot and ankle surgeon at an academic medical center. A total of 326 patients (356 feet) were included with a mean follow-up up of 2.12 (range, 1.00-4.98) years. Data collected included demographics, medical comorbidities, treatment history, complications and reoperation rates, patient-reported outcome measures (eg, Foot and Ankle Outcome Score), and opioid exposure.ResultsThere were significantly more complications among opioid exposed patients than opioid naïve ones (exposed = 29.41%, naïve = 9.62%; P = .044). Preoperative opioid exposure significantly correlated with postoperative opioid exposure (90-day: r = .903, p < .001; 180-day: r = .805, p < .001), and increased hospital length of stay (r = .263, p = .029). Furthermore, body mass index was a significant predictor of postoperative opioid exposure (90-day: r = .262, p = .013; 180-day: r = .217, p = .021), as was concomitant mental illness (90-day: r = .225, p = .035).ConclusionPatients with preoperative opioid exposure have significantly more complications and increased postoperative opioid exposure after foot and ankle surgery.Levels of Evidence:Level III: Retrospective cohort study.
