Which Measure Groups Drove Improvement Among 5 Star Rated Hospitals in 2022?

CMS Overall Hospital Quality Star Ratings assess hospitals on the following 5 measure groups:

  • Mortality

  • Safety

  • Readmission

  • Patient Experience

  • Timely & Effective care

These measure groups are standardized to have a mean of 0 and a standard deviation of 1. Each measure group is scored across various individual measures and a summary score is calculated to rate the hospitals from 1 star to 5 Stars, with 5 being the highest Star Rating a hospital can achieve. In 2022, CMS has given 5 Star Ratings to 431 hospitals out of 3121 hospitals that received a Star Rating. These would make up roughly 14% of the total number of hospitals that were rated for 2022.

Among these, 300 hospitals retained their 5 Star rating from the previous year. 12 hospitals jumped from 3 Stars to 5 in 2022 Star Ratings and 118 hospitals jumped from 4 Stars in 2021 to 5 in 2022. An understanding of the areas in which these hospitals have improved to achieve 5 Star Ratings can provide a roadmap to improvement for other hospitals. In light of this, this article takes a closer look at the measure groups that the hospitals improved on in 2022 to achieve their 5 Star Ratings.

The 130 hospitals that improved their scores to a 5 Star Rating in 2022 have shown improvement across 4 out of 5 measure groups.The highest improvement is seen in the Readmission scores with an average improvement from 2021 of 0.36. This is followed by Mortality and Safety scores.
