Centers of Occupational Health & Education (COHE)

Research and Results

L&I's Health Services Analysis team works with Centers of Occupational Health & Education (COHEs) to pilot new best practices. These occupational health best practices are often developed in partnership with the University of Washington (UW).

UW has evaluated the COHEs and found that workers treated by COHE providers have fewer time-loss days and their claims have overall lower costs. These savings benefit employers and workers by lowering injury costs.

From the extensive evaluation by the UW, the program has transitioned to a quarterly report that illustrates the overall aggregated impact of the COHEs. Measurement information is supplied by L&I Research & Data Services and L&I Actuarial Services.

L&I works to ensure that best practices are implemented successfully and that COHEs are given data that helps them provide the best service to providers, employers, and workers.
