Objective: To evaluate the quality of care provided to individuals with workers’ compensation claims related to Carpal tunnel syndrome (CTS) and identify patient characteristics associated with receiving better care.

Methods: We recruited subjects with new claims for CTS from 30 occupational clinics affiliated with Kaiser Permanente Northern California. We applied 45 process-oriented quality measures to 477 subjects’ medical records, and performed multivariate logistic regression to identify patient characteristics associated with quality.

Results: Overall, 81.6% of care adhered to recommended standards. Certain tasks related to assessing and managing activity were underused. Patients with classic/probable Katz diagrams, positive electrodiagnostic tests, and higher incomes received better care. However, age, sex, and race/ethnicity were not associated with quality.

Conclusions: Care processes for work-associated CTS frequently adhered to quality measures. Clinical factors were more strongly associated with quality than demographic and socioeconomic ones.

This work was funded by a grant from the Agency for Healthcare Research and Quality (5R01HS018982–03). Prior stages in the work (quality measure development) were supported with funding from the California Commission on Health and Safety and Workers’ Compensation (CHSWC) and with an unrestricted gift from Zenith Insurance. CHSWC is a state-sponsored joint labor-management body charged with examining the health and safety and workers’ compensation systems in California and recommending administrative or legislative modifications to improve their operation. Zenith Insurance specializes in workers’ compensation insurance. The funders played no role in the design, conduct, or reporting of this work.

RAND has received funding from Insurance and Care NSW, Australia (Nuckols), and from the Collaborative Spine Research Foundation (Nuckols). The authors have no other potential conflicts of interest to report.
