National Rankings for Hospitals

We computed hospital rankings using publicly reported data downloaded from the Centers for Medicare & Medicaid Services (CMS) Hospital Compare website (www.hospitalcompare.hhs.gov - last accessed 3/26/09¹). This data set contains hospital-specific performance on 25 quality measures for over 4,500 hospitals nationwide².

Hospitals voluntarily report these data, and some hospitals may not provide data for some topics or measures. For each measure the denominator is the number of eligible cases, and the numerator is the number of eligible cases where the recommended care was provided³. The overall success rate for each hospital is calculated by summing the numerators and denominators for all measures reported. We rank hospital performance on this overall rate and then convert the ranks to percentiles. Our analysis uses all performance measures included in the database and does not exclude any hospitals or measures based on the number of cases in the denominator. This means that for some hospitals the rankings are based on only a few eligible cases; and the rankings for these facilities should be interpreted cautiously. Results will be displayed in a new window.

Please select your state's initials and press the Show Results button.

Update: You can now sort the results by clicking on any of the headings in the results table (ie. Hospital, City, AMI, HF, Pneumonia, SIP, or National Ranking). Also, clicking on a hospital will provide detailed historical data for that hospital's rank and overall performance rate for the past 7 quarters. This will also show as graphical charts in the lower half of the window.

These data have limitations that people should be aware of when interpreting the data. For more information click here.
