This study will provide a longitudinal, program focused account of the impacts of programs funded by the new Pierce County Behavioral Health Fund. This study tests the assumption that behavioral health programs divert patients from emergency systems by tracking their usage of medical services pre and post behavioral health intervention programs. Our research will show if these programs are effective in diverting patients with behavioral health issues away from more expensive systems. Our research will use hazard rates and other modeling work to show the impacts of these programs. Our work will have implications for Pierce County’s procurement of behavioral health services for its constituents (to be explicit, not its employees) and allow for the county to reward improvement over time. It will enable providers and hospitals and the behavioral health system more broadly to make informed choices about behavioral health programs and improve their benchmarking. This sort of data analysis will also hopefully provide a model for other counties on how to use the APCD for this sort of work.
