CMS Compare 5-Star Rating

EvergreenHealth Medical Center earned a 5-star rating in the 2021 Hospital Compare overall quality systems rankings conducted by the Centers for Medicare & Medicaid Services (CMS).

EvergreenHealth was one of just 455 hospitals nationwide–and just three in the Seattle areato receive the 5-star designation. 

Achieving a five-star rating represents EvergreenHealth's high scores across a range of quality measures.

CMS' Hospital Compare reviewed 4,500 hospitals nationwide on five criteria:

  • mortality
  • safety of care
  • readmission rates
  • patient experience
  • timeliness of care

The overall hospital rating ranges from one to five stars, with more stars reflecting higher performance.

Hospital Compare's aim is to help improve hospitals' quality of care through easy-to-understand data on hospital performance, and quality information from patient perspectives.
