The 2018 Washington State Legislature directed WSIPP to complete a study of single payer and universal coverage health care systems. The study will include a summary of the parameters used to define universal coverage, single-payer, and other innovative systems; a comparison of the characteristics of up to ten universal or single payer models available in the United States or elsewhere; and a summary of the available research literature that examines the effect of universal or single player models on health-related outcomes.
The original deadline was December 1, 2018, however, WSIPP's Board of Directors approved a modification. A preliminary report
was released in December 2018. A final report is due to the legislature by June 30, 2019.
