When CMS updated the methodology used in its Overall Hospital Quality Star Rating program in December after a five-month delay, the number of hospitals that received the highest possible overall rating increased from 83 in December 2016 to 337.
CMS' Hospital Compare website reports on quality measures for more than 4,000 hospitals from around the country. Changes in the specific methodology used to stratify the ratings include the removal of winsorization from the statistical breakdown. Winsorization is a process that limits extreme values from arising in statistical analysis. As a result, the new ratings have a higher number of 5-star and 1-star hospitals.
Below is a listing of 337 hospitals that received five stars from CMS in December, broken down by state, as listed on the Hospital Compare website.
