The Influence of Insurance Status on Extensor Tendon Repair Outcomes

Le résumé fourni par la source

Background: Little is known regarding how patient insurance status influences outcomes after extensor tendon-injury repair. We aim to establish a relationship between the outcomes of primarily repaired extensor tendon injuries and patient insurance status. We hypothesize that commercially insured patients will achieve superior outcomes due to more facile access to postoperative hand therapy and fewer barriers to appropriate postoperative care. Methods: A retrospective chart review was conducted of patients who underwent primary extensor tendon repair in any zone, excluding the thumb, at a single large safety-net hospital. Inclusion criteria included a minimum of eight weeks of follow-up, complete data available for review, and an extensor tendon injury requiring primary surgical repair. Four cohorts were examined: patients with commercial insurance, patients with Medicare/Medicaid, patients with county hospital-sponsored insurance, and uninsured patients. Statistical analysis was performed using Chi-Square and ANOVA analyses, with significance defined as p ≤ 0.05. Results: Of the 62 patients (100 digits) included, 20 had commercial insurance, 12 had Medicare/Medicaid, 13 had hospital-sponsored insurance, and 17 were uninsured. Except for mean age, there were no significant differences between groups in terms of demographic data, medical comorbidities, or digit characteristics. There were also no significant differences in mean follow-up, time to return to full activity, or surgical complications among groups. Procedure duration differed significantly between groups, with procedures lasting longer in uninsured patients. Postoperative final flexion total arc of motion (TAM) and extension measurements were similar across all groups. Additionally, hand therapy visits did not differ significantly between groups. Conclusions: Following extensor tendon repair, patient insurance status did not affect outcomes in terms of final range of motion, return to full activity, or postoperative complications.
