HealthGrades study shows a large variance in quality at U.S. hospitals

Patients Have a 52% Lower Chance of Dying at Top-Rated Hospitals

HealthGrades released The Twelfth Annual HealthGrades Hospital Quality in America Study which examined nearly 40 million Medicare hospitalization records for the years 2006, 2007 and 2008. The study looks at trends in mortality and complication rates and also provides the foundation for HealthGrades’ quality ratings of procedures and diagnoses at each individual hospital.

According to the HealthGrades press release, The largest annual study of patient outcomes at each of the nation’s 5,000 nonfederal hospitals found a wide gap in quality between the nation’s best hospitals and all others. According to the study, patients at highly rated hospitals have a 52% lower chance of dying compared with the U.S. hospital average, a quality chasm that has persisted for the last decade even as mortality rates, in general, have declined.

The Twelfth Annual HealthGrades Hospital Quality in America Study shows that a large gap exists between the top-performing, highest quality hospitals and the rest of the hospitals in the country. After examining 40 million Medicare hospitalization records dating from 2006 through 2008, HealthGrades found that patients treated at a top hospital were 52% less likely to die as a result of their care, as compared with the average American hospital.
