ObjectiveTo determine the influence of preoperative workers' compensation (WC) status on patient-reported outcome measures following lumbar decompression with or without fusion.MethodsAll patients undergoing lumbar decompression with or without fusion at a single academic institution between 2013 and 2017 were identified. Patients were split into groups based on WC status: no workers' compensation (NWC), WC), or retired. Intragroup analysis used paired t tests. Outcomes between groups were compared using Kruskal-Wallis H test. Multiple linear regression analysis determined if WC status was a predictor of change in patient-reported outcome measures. Subgroup analysis was conducted for WC patients who returned to work.ResultsOf 571 included patients, 242 (43.4%) had NWC, 83 (14.5%) had WC, and 246 (43.1%) were retired. Comparing within groups, WC patients showed significant improvement in Short Form-12 Health Survey Physical Component Score, Oswestry Disability Index, visual analog scale (VAS) back pain, and VAS leg pain (all P < 0.001) after surgery. However, WC patients improved less than NWC or retired patients in Short Form-12 Health Survey Physical Component Score (P = 0.010), VAS back pain (P = 0.028), and VAS leg pain (P = 0.015). WC was an independent predictor of decreased improvement in Short Form-12 Health Survey Physical Component Score (β = -4.31, P = 0.001), VAS back pain (β = 0.90, P = 0.034), and VAS leg pain (β = 1.50, P = 0.002) on multivariate analysis. WC patients who did not return to work was an independent predictor of decreased improvement in VAS back pain (β = 1.39, P = 0.016) and VAS leg pain (β = 2.11, P = 0.001).ConclusionsWC patients improve less than NWC patients. However, WC patients who return to work have similar VAS back and neck pain improvements as NWC patients.Copyright © 2022 Elsevier Inc. All rights reserved.
