Quality ratings for medical practices, hospitals, and statewide performance:

The WA-APCD medical practice and hospital quality measures use measures drawn from the Washington Statewide Common Measure Set –state performance measures for health care accountability and performance.  The Common Measure Set is comprised of more than 50 measures of health care quality and value. Most of these measures are part of national measurement systems sponsored by the National Committee for Quality Assurance (NCQA) and the Centers for Medicare and Medicaid Services (CMS).  Additionally, Washington state agencies have authored select measures.

Statewide performance results are reported by the nine Accountable Communities of Health (ACH) regions and by the major health insurance market sectors. Patients, based on residence, are grouped into the nine ACHs to produce the regional results.  Similarly, patients, based on their insurance coverage, are grouped by their insurance coverage -- commercial, Medicaid and the Washington Health Benefits Exchange -- to produce results by these three insurance market sectors.

Performance results are computed separately for the commercial and Medicaid populations. For a few measures, only Medicaid results are reported as the commercial population data is not available.  Some of the hospital measures are based on patients across all insurance programs -- Medicare, commercial, and Medicaid; other hospital measures include care and experiences for Medicare patients only.
