HealthGrades recently examined 40.6 million Medicare hospitalization records in preparation for their 2007 report. The results show that the gap between the best and worst performing hospitals is growing. For instance, there is a 60% lower chance of dying at one of the nation’s 5-star rated hospitals than at one of the 1-star rated hospitals. If all hospitals performed at the level of a 5-star hospital across 18 of the procedures and diagnoses studies, 302,403 Medicare lives could have potentially been saved from 2003 through 2005. 50% of the potentially preventable deaths were associated with 4 diagnoses: Heart Failure, Community Acquired Pneumonia, Sepsis, and Respiratory Failure.
