In 2020, the Centers for Medicare & Medicaid Services (CMS) overhauled the Hospital Overall Quality Star Ratings methodology with the expressed purpose of making ratings more transparent, equitable, stable and predictable.
AHA commissioned KNG Health to assess whether these methodological changes have fully achieved CMS' goals, while also estimating expected performance variation and drivers of performance and variation under the new methodology. Based on this analysis, it’s clear that CMS has more work to do to ensure that these ratings are equitable.
