The Association of Insurance Status and Complications After Carpal Tunnel Release

Background: Carpal tunnel release (CTR) is one of the most commonly performed procedures in hand surgery. Complications from surgery are a rare but significant patient dissatisfier. The purpose of this study was to determine whether insurance status is independently associated with complications after CTR. Methods: We retrospectively identified all patients undergoing CTR between 2008 and 2018 using the Indiana Network for Patient Care, a state-wide health information exchange, and built a database that included patient demographics and comorbidities. Patients were followed for 90 days to determine whether a postoperative complication occurred. To minimize dropout, only patients with 1 year of encounters after surgery were included. Results: Of the 26 151 patients who met inclusion criteria, 2662 (10.2%) had Medicare, 7027 (26.9%) had Medicaid, and 16 462 (62.9%) had commercial insurance. Compared with Medicare, Medicaid status (P < .001) and commercial insurance status (P < .001) were independently associated with postoperative CTR complications. The overall complication rate was 2.23%, with infection, wound breakdown, and complex regional pain syndrome being the most common complications. Younger age, alcohol use, diabetes mellitus, hypertension, and depression were also independently associated with complications. Conclusions: The incidence of complications after CTR is low. Insurance status, patient demographics, and medical comorbidities, however, should be evaluated preoperatively to appropriately risk stratify patients. Furthermore, surgeons can use these data to initiate preventive measures such as working to manage current comorbidities and lifestyle choices, and to optimize insurance coverage.
