First Year APCD Collected Data: 
APCD Snapshot: 
Puget Sound Health Alliance kicked off in 2004 by King County Executive Ron Sims in response to concerns about rising health care costs and quality in the delivery of health care services. King County rallied business groups to the table and started the Puget Sound Health Alliance (now called the Washington Health Alliance). The Alliance is a purchaser-led, multi-stakeholder collaborative. One of the initiatives of the Alliance was to develop a claims database. Today, the Alliance’s database comprises approximately 65% of the non-Medicare claims in the region. The database currently captures information from 1/1/2004 through 12/31/2016, representing over 4 million lives and approximately 1.6 billion claim lines from commercial insurance, managed Medicaid and Medicaid Fee for Service. Since its beginning, the Alliance focused on a 5-county area in the greater Seattle metropolitan area (the Puget Sound region). In late 2013, the Alliance re-branded itself the Washington Health Alliance and expanded its various activities statewide, including performance measurement and public reporting. At present, access to the Alliance’s database by researchers and other interested parties is possible but is quite limited.
