Clinical quality measures for electrodiagnosis in suspected carpal tunnel syndrome.

Extensive research has documented that medical care in the United States is not of optimal quality, meaning that well-established care processes are not consistently provided to the patients who would benefit from them. To assess and improve quality of care, specific measures are needed. The objective of this study was to develop quality measures for electrodiagnostic testing in suspected carpal tunnel syndrome (CTS). We used a variation of the well-established RAND/UCLA Appropriateness Method to develop the measures. A physiatrist and quality measurement experts developed draft measures based on guidelines and literature. Subsequently, in a two-round, modified-Delphi process, a multidisciplinary panel of 11 national experts in CTS reviewed a summary of the evidence and then rated the measures for validity and feasibility. Seven draft measures were developed. The expert panel combined two, modified the others, and then judged all resulting measures to be valid and feasible. The measures cover compelling indications for testing, essential test components when CTS is suspected, skin temperature measurement and normalization, and the appropriate interpretation of test results. These measures define a minimum standard of care for the use of electrodiagnostic tests in suspected CTS and are consistent with recent guidelines developed by the American Association of Neuromuscular and Electrodiagnostic Medicine. Provider organizations, insurance companies, and professional societies can use these measures in efforts to monitor and improve quality of care for this common and disabling condition.
