ObjectiveTo evaluate outcomes for workers' compensation (WC) patients versus patients with commercial insurance (CI) undergoing lumbar decompression at an ambulatory surgical center.MethodsThis is a retrospective cohort study utilizing propensity score matched groups. Patients undergoing elective lumbar decompression at an ambulatory surgical center with 2-year follow-up were identified and grouped based on insurance type (WC or CI). Other demographic, diagnostic, and patient-reported outcome (PRO) data were obtained as well. PROs included Patient-Reported Outcome Measurement Information System-Physical Function, Visual Analog Scale-Back, Visual Analog Scale-Leg, Oswestry Disability Index, 12-Item Veterans Rand (VR-12) Physical Composite Score, VR-12 Mental Composite Score, and 9-Item Patient Health Questionnaire (PHQ-9). PRO scores were obtained preoperatively and up to two years postoperatively. Rates of minimum clinically important difference were obtained. Multivariate regression was utilized to compare postoperative PROs.ResultsFollowing propensity score matching, 153 patients remained in the CI group and 71 were in the WC group. At baseline through one year postoperatively, WC patients reported worse Oswestry Disability Index, PHQ-9, Patient-Reported Outcome Measurement Information System-Physical Function, VR-12 Physical Composite Score, and VR-12 Mental Composite Score (P ≤ 0.041, all). At two years, WC patients reported similar outcomes as CI patients. WC patients reported significantly greater minimum clinically important difference achievement for PHQ-9 (73.1% vs. 37.7% for CI patients, P = 0.008).ConclusionsWC patients report inferior preoperative and postoperative outcomes in disability, mental health, and physical function compared to CI patients. However, WC patients were more likely to report clinically significant improvements in depressive burden. Surgeons can counsel WC patients on expected mental health improvements and recommend psychosocial and physical rehabilitation.Copyright © 2024 The Author(s). Published by Elsevier Inc.
