WA-APCD Data Requests

In managing the data release process, the WA-APCD balances the State’s interest in promoting public reporting of health care information with careful adherence to privacy and security safeguards and appropriate data uses. Release of WA-APCD data is allowable provided the data request is approved per the criteria established by the WA-APCD Lead Organization which is guided by the WA-APCD statute (Chapter 43.371 RCW), rules (Chapter 182-70 WAC), and the WA-APCD Data Release Advisory Committee.
