HealthGrades ratings reflect hospital track records
The HealthGrades study, the largest annual report of its kind, analyzed patient outcomes in nearly 40 million Medicare hospitalization records from 5,000 hospitals from 2006 through 2008.
HealthGrades’ hospital ratings and awards reflect the track record of patient outcomes at hospitals in the form of mortality and complication rates. HealthGrades rates hospitals independently based on data that hospitals submit to the federal government. No hospital can opt in or out of being rated, and no hospital pays to be rated.
For 28 procedures and treatments, HealthGrades issues star ratings that reflect the mortality and complication rates for each category of care. Hospitals receiving a five-star rating have mortality or complication rates that are below the national average to a statistically significant degree.
A three-star rating means the hospital performs as expected. One-star ratings indicate the hospital’s mortality or complication rates in that procedure or treatment are statistically higher than average. Because the risk profiles of patient populations at hospitals are not alike, HealthGrades risk adjusts the data to allow for apples-to-apples comparisons.
