Abstract

Background: Carpal tunnel syndrome (CTS) is the most common peripheral mononeuropathy and thus is frequently encountered by general practitioners (GPs). The aim of this study is to investigate the referral pattern of GPs with regard to electrodiagnostic (EDX) testing for suspected CTS prior to hand surgery consultation, as well as to investigate the results of EDX testing for suspected CTS when requested by GPs prior to evaluation by a hand surgeon.

Methods: We retrospectively reviewed patients referred to our hand surgery clinic over a consecutive 2-year period for suspected CTS.

Results: A total of 403 patients were referred to our hand surgery clinic from January 1, 2016, to December 31, 2017. Of the 403, 295 (73.2%) were referred by GPs. GPs obtained prereferral EDX testing in 198 (67.1%) of these patients. EDX testing confirmed their diagnosis in 177 patients (89.4%). There were 21 patients (10.6%) identified with normal EDX testing and a more likely diagnosis reached based on clinical examination.

Conclusions: GPs make up the majority of our referrals for CTS, and they obtain EDX testing prior to consultation in two-thirds of referrals. GPs appear to accurately utilize EDX testing to confirm their diagnosis prior to referral and have a low rate of normal testing where symptoms are more readily explained by an alternative diagnosis.
