title: Carpal tunnel syndrome and workers' compensation: A cross-Canada comparison.
abstract: Carpal tunnel syndrome (CTS) is the source of substantial workers' compensation claims in industrialized countries. Its pathogenesis, however, continues to be questioned. The purpose of the present study was to assess the attitudes of Canadian plastic surgeons toward Workers' Compensation Board (WCB)-supported claims for CTS and to assess patterns of resource allocation across Canada. Sixty-seven plastic surgeons were asked to read a clinical scenario and respond whether they would support a WCB claim for CTS. Provincial WCB offices were contacted and asked to provide statistics surrounding CTS claims for 1997 to 2001. Fifty-eight per cent (39 of 67) of surgeons surveyed felt that CTS should be covered as a WCB claim, while 42% (28 of 67) felt that it should not be covered by WCB. In British Columbia, 50% (six of 12) of surgeons were in support of the claim compared to 92% (11 of 12) of those from Alberta, 55% (17 of 31) of those from the Central Provinces and 42% (five of 12) of those from the Maritime Provinces. Trends of resource allocation and number of CTS claims per year are presented for the individual provinces for 1997 to 2001. An extensive literature review revealed that there is minimal to no evidence to support the view that CTS should be a compensated claim. As defined by the WCB of Canada, a compensated claim is one that "arises out of, and in the course of, employment and that results from causes and conditions peculiar to the trade, occupation or industry." The ambiguity in the beliefs of Canadian plastic surgeons in supporting CTS as a WCB claim reflects a situation where many of the decisions to cover CTS as a WCB claim are not evidence based.
