Health Systems Quality Assurance

Health System Quality Assurance's top priority is to protect and improve the health of people in Washington State. We do this by helping to prevent injuries, develop health systems and improve patient safety. We work closely with communities and local health partners to build strong health systems and prevention programs. This helps ensure that everyone has access to good healthcare and emergency medical services.

Health Systems Quality Assurance (HSQA) regulates and supports more than 404,000 health professionals in 83 health professions, and 7,000 health groups and programs. Each year we review nearly 9,800 complaints and inspect thousands of facilities. Each month we respond to about 20,000 phone calls and thousands of emails.
