CMS updated its Overall Hospital Quality Star Ratings on its Hospital Compare website April 28. The updated ratings are based on CMS' revised methodology.
Four things to know:
1. CMS' star rating system, launched in 2016, assigns stars based on 48 measures in the following five categories: mortality, safety of care, readmission, patient experience, and timely and effective care. This differs from CMS' previous method, which included 65 measures across seven groups.
2. Here is a breakdown of the updated star ratings:
- One-star: 204 hospitals
- Two-stars: 690
- Three-stars: 1,018
- Four-stars: 988
- Five stars: 455
3. Overall, 50 percent of hospitals received the same rating, 45 percent moved up or down by one star, and 5 percent shifted up or down by two or more stars.
4. CMS last updated its star ratings in January 2020.
