| Summary: | Background:. Carpal tunnel release is a life-changing procedure within hand surgery. Multiple factors may have an impact on the outcome following surgery.
Methods:. In this retrospective cohort study, we reviewed all patients who underwent carpal tunnel release in our institutional database from 2018 to 2020. We included patients with a minimum of 6-week follow-up. Patient demographics were identified, including insurance status and comorbidities. Patients were categorized as “improved” or “not improved” based on two-point test differences. Results were analyzed using the Fisher exact test. We ran a logistic regression model to analyze the relationship between income status (operationalized by having Medicaid/Carelink) and preoperative scores, and inferential statistics were computed with appropriate t tests.
Results:. Of the 125 patients who met the inclusion criteria, 47 (37.6%) had Medicaid or Carelink, and 79 (62.4%) had commercial insurance. Medicaid/ Carelink patients presented with worse two-point discrimination on initial presentation (P < 0.001). Compared to commercial insurance, Medicaid/Carelink patients were less likely to show improvement in postoperative two-point discrimination (P < 0.001). Male patients were also less likely to show improvement. Race, ethnicity, medical comorbidities, and age were not shown to have a significant effect on improvement in two-point discrimination.
Conclusions:. Although medical comorbidities did not have a significant effect on postoperative two-point, patients with low-income status (Medicaid/Carelink) may have a less predictable outcome. These socioeconomic considerations are critical in appropriately risk stratifying surgical candidates, and counseling patients in whom tactile acuity may be less predictable.
