Evaluation of a Comprehensive Telemedicine Pathway for Carpal Tunnel Syndrome: A Comparison of Virtual and In-Person Assessments.

PURPOSE: We evaluated a comprehensive telemedicine pathway for carpal tunnel syndrome (CTS). Our primary aim was to compare telemedicine and in-person administration of the six item CTS-6 instrument (CTS-6) in patients undergoing carpal tunnel release (CTR) and to determine whether surgical plans determined via telemedicine were altered by in-person assessments. We additionally aimed to assess agreement between telemedicine and in-person examinations.

METHODS

In this prospective investigation, patients referred to a hand surgeon for evaluation of CTS were offered a telemedicine pathway. A modified, virtual CTS-6 was administered during the telemedicine consultation and a virtual exam was performed. Patients indicated for CTR were evaluated in person on the day of surgery. Agreement between the telemedicine and in-person CTS-6 and exam findings was determined. Patients were evaluated via telemedicine postoperatively to determine satisfaction with the program and assess surgical complications.

RESULTS

A total of 32 cases were included. The mean CTS-6 score administered via telemedicine was 17.7, compared with 16.8 in person; this difference was not statistically significant. There were no cases indicated for CTR during the telemedicine visit that had a subsequent change in management based on the in-person evaluation. Agreement was lowest for the sensory assessment (63%). The Phalen and Durkan compression tests demonstrated high levels of agreement (97% and 94%, respectively). Satisfaction was high for patients in the telemedicine CTS pathway.

CONCLUSIONS

Overall agreement between telemedicine and in-person administration of the CTS-6 is high for patients with CTS. In patients indicated for CTR via telemedicine, an in-person examination does not appear to alter management. The telemedicine examination of hand sensation demonstrates lower levels of agreement with the in-person assessment. Telemedicine can serve as an alternative to conventional, in-person clinic visits for the diagnosis and postoperative management of uncomplicated, primary CTS.
