At Healthgrades, better health gets a head start....Healthgrades evaluates hospitals solely on risk adjusted mortality and in-hospital complications. Its website evaluates roughly 500 million claims from federal and private reviews and data to rate and rank doctors based on complication rates at the hospitals where they practice, experience, and patient satisfaction. Its analysis is based on approximately 40 million Medicare discharges for the most recent three-year time period available. Hospital rating reports for specific procedures and diagnoses are compiled primarily from Medicare claim data, and include all hospitals that are medicare participants. Some critics argue that claim data is not adequate enough to make determinations about the quality of care and that conclusions should be drawn from medical records.
Peer-reviewed research has shown that measures of mortality and complication rates based on administrative data can be used as a measure of clinical quality. Ratings are updated yearly, but data is two years old before Medicare releases it. Healthgrades develops objective ratings based on data and information obtained from several sources, mostly available to the public. The data is analyzed using a proprietary methodology that identifies the recipients of the various awards and the "1-3-5 Star" designation.
Specifically, most ratings are determined from multivariate logistic regressions of medical outcomes at a given healthcare provider to risk-adjust the patients and 1-, 3- and 5-star awards are given to providers whose negative outcomes are worse than expected, near predicted levels, and better than expected, respectively. The ratings have been criticized for oversights in the methodology that may actually penalize some institutions with ideal medical outcomes.
