Disparities in Treatment of Closed Distal Radius Fractures in Patients Aged 18-64 Years and ≥65 Years by Insurance Type.

PURPOSE: Type of and time to definitive treatment for distal radius fractures can influence the outcomes. The impact of social determinants of health (eg, insurance type) on distal radius fracture care remains unknown despite having health equity implications. Thus, we evaluate the association between insurance type and rate of surgery, the time to surgery, and the complication rate for distal radius fractures. METHODS: We conducted a retrospective cohort study using the PearlDiver Database. We identified adults with closed distal radius fractures. Patients were divided into subgroups by age (18-64 years, 65+ years) and further stratified on the basis of the insurance type (Medicare Advantage, Medicaid-managed care, and commercial). The primary outcome was the rate of surgical fixation. Secondary outcomes included the time to surgery and 12-month complication rates. Logistic regression modeling was used to calculate the odds ratios for each outcome, adjusting for age, sex, geographic region, and comorbidities. RESULTS: In patients aged ≥65 years, a lower proportion of Medicaid patients underwent surgery within 21 days of diagnosis compared with Medicare or commercially insured patients (12.1% vs 15.9% or 17.5%, respectively). Complication rates did not differ between Medicaid and other insurance types. In patients aged
