Funded by the 2019 Legislature (ESHB 1109), the Better Health Through Housing pilot program sought to reduce health care costs by providing housing and other services to homeless, frequent emergency department visitors with complex healthcare needs. The program was administered by the Department of Commerce and implemented by Better Health Together, an Accountable Community of Health located in northeastern Washington. This report describes program implementation and the experiences and characteristics of individuals referred to the pilot, including their: 1) progression through key program milestones; 2) health histories; and 3) medical utilization patterns before and after referral to the program.
