Socioeconomic Disparities in Surgical Care for Congenital Hand Differences.

Background: The purpose of this study was to evaluate the influence of socioeconomic factors on access to congenital hand surgery care, hospital admission charges, and analyze these geographic trends across regions of the country.

Methods: Retrospective cohort study was conducted of congenital hand surgery performed in the United States from 2010 through 2020 using the Pediatric Health Information System. Multivariate regression was used to analyze the impact of socioeconomic factors.

Results: During the study interval, 5531 pediatric patients underwent corrective surgery for congenital hand differences, including syndactyly repair (n = 2439), polydactyly repair (n = 2826), and pollicization (n = 266). Patients underwent surgery at significantly earlier age when treated at above-median case volume hospitals (P < .001). Patients with above-median income (P < .001), non-white race (P < .001), commercial insurance (P < .001), living in an urban community (P < .001), and not living in an underserved area (P < .001) were more likely to be treated at high-volume hospitals. Nearly half of patients chose to seek care at a distant hospital rather than the one locally available (49.5%, n = 1172). Of those choosing a distant hospital, most patients chose a higher-volume facility (80.9%, n = 948 of 1172). On multivariate regression, white patients were significantly more likely to choose a more distant, higher-volume hospital (P < .001).

Conclusions: Socioeconomic and geographic factors significantly contribute to disparate access to congenital hand surgery across the country. Patients with higher socioeconomic status are more likely to be treated at high-volume hospitals. Treatment at hospitals with higher case volume is associated with earlier age at surgery and decreased hospital admission charges.
