Washington Alliance of Health Data Exchange
Statewide Health & Social Data Infrastructure for a Stronger, Healthier Washington
Overview
Launched in January 2026, the Washington Alliance of Health Data Exchange (WAHDX) is Washington State’s shared, secure, and equitable health and social data infrastructure. WAHDX enables authorized partners—including community health organizations, providers, payers, public health agencies, social service entities, and researchers—to access the trusted data they need to:
Improve care delivery
Strengthen community well‑being
