Thomson Reuters releases fourth annual list of top U.S. health systems

Thomson Reuters has released its fourth annual list of the top U.S. health systems based on quality, patient satisfaction, and efficiency, according to a press release.

To compile the list, Thomson Reuters examined data from 2010 Medicare Provider Analysis and Review and from CMS Hospital Compare for U.S. health systems. Researchers looked at eight metrics to rate clinical quality and efficiency: mortality, medical complications, patient safety, average length of stay, 30-day mortality rate, 30-day readmission rate, adherence to clinical standards of care and HCAHPS patient satisfaction score. 

The top 15 hospitals were grouped by operating size.  The list is:
