Overall Hospital Quality Star Ratings Updated on Medicare Care Compare

Share this:

Overall hospital quality star ratings have been updated on the Centers for Medicare and Medicaid Services (CMS) Care Compare Website for over 4,500 U.S. hospitals. The overall hospital quality star ratings now include new methodology in five measure groups – mortality, safety of care, readmission, patient experience and timely and effective care.

The star rating summarizes a variety of measures across five areas of quality into a single star rating for each hospital. Once reporting thresholds are met, a hospital’s overall star rating is calculated using only those measures for which data are available, the average is about 37 measures.

Only hospitals that have at least three measures within three measure groups with at least one of those groups being mortality or safety of care, are eligible for an overall star rating. Not all hospitals report all measures so some hospitals may not be eligible.

For each hospital, a summary score is calculated by taking the weighted average of the hospital’s scores for each measure group or category. Mortality is weighted at 22%; safety at 22%; readmission at 22%; patient experience at 22%; and timely and effective care at 12%.

Under an interim final rule released in August (AHT, 8/7/2020), CMS did not use quality data from January 1 through June 30 2020. For the April 2021 update to overall star ratings, CMS used October data to calculate the ratings. CMS did not update the overall hospital quality star ratings at Hospital Compare in January 2020 to allow time to review public comment and finalize proposed changes to the star ratings methodology (AHT, 11/18/2020). The next quarterly update to Hospital quality data on Care Compare will be July 2021.
