The Risk-Adjusted Mortality Rate** is a outcome measure developed to normalize mortality rates. The Hospital Compare risk-adjusted mortality rates are based on Medicare Fee-for-Service patients, at least 65 years of age, hospitalized with a principal discharge diagnosis of acute myocardial infarction (AMI), heart failure (HF), or pneumonia (PN) for which death occurs within 30 days of admission.

Hospitals are shown to be Better or Worse Than U.S. National Rate only if we can be 95% certain that the difference between their risk-adjusted death (mortality) rates and the U.S. National rate is not due to chance. All others are shown in the No Different Than U.S. National Rate category.

Better Than U.S. National Rate

Hospitals in the Better Than U.S. National Rate category have 30-day risk-adjusted death (mortality) rates that are lower than the U.S. National rate, and we can be 95% certain that this difference is not due to chance.

No Different than U.S. National Rate

Many hospitals in the No Different Than U.S. National Rate category have 30-day risk-adjusted death (mortality) rates that are about the same as the U.S. National rate. Other hospitals in this category have rates that are higher or lower than the U.S. National rate, but we cannot be 95% certain that these differences are not due to chance. One cannot be certain about differences when a hospital has very few relevant patients.

Worse Than U.S. National Rate

Hospitals in the Worse Than U.S. National Rate category have 30-day risk-adjusted death (mortality) rates that are higher than the U.S. National rate, and we can be 95% certain that this difference is not due to chance.

    Note: Medicare derived the 30-Day Risk-Adjusted Death (Mortality) measures from its own data about patients on Original Medicare and the hospitals that treat them. The information in this table reflects care given only to patients who are on Original Medicare. All data are risk-adjusted.

    These percentages were calculated from Medicare data on patients discharged between July 2008 and June 2011. They do not include people in Medicare Advantage (managed care) plans or people who do not have Medicare.
