Socioeconomic Status Affects Pre- and Postoperative Two-point Discrimination in Patients with Carpal Tunnel Syndrome.

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 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 ( 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.
