four groups based on these rates, 35 ranked hospitals (70 percent) were in the group with the fewest deaths, 11 (22 percent) were in the middle two groups and four (8 percent) were in the worst-performing group.
Eleven ranked hospitals (22 percent) and 28 non-ranked hospitals (0.73 percent) had standardized mortality ratios significantly less than one, meaning that although ranked hospitals were more likely to have lower-than-expected death rates, non-ranked hospitals with favorable ratios outnumbered ranked hospitals with similar performance by nearly three to one.
As a result, the U.S. News & World Report ranking list does not include many hospitals that have outstanding performances for the care of patients with acute myocardial infarction, or heart attack, the authors write.
One reason for this may be the reputation component of the rankings, which accounts for one-third of the overall ranking score and is based on cardiologists opinions of hospitals that provide the best treatment, the authors speculate.
Citations by cardiologists likely favor tertiary centers with strong subspecialty care for the most critically ill patients while not necessarily reflecting the perceived care for the overwhelming majority of admissions for more common diagnoses, which in turn have a more substantial impact on overall hospital outcomes, they continue.
The U.S. News & World Report ranking, which includes many of the nations most prestigious hospitals, did identify a group of hospitals that was much more likely than non-ranked hospitals to have superb performance on 30-day mortality after acute myocardial infarction, the authors conclude.
However, our study also revealed that not all ranked hospitals had outstanding performance and that many non-ranked hospitals performed well. Consequently, although the U.S. News & World Report rankings provide some guidance about the performance on outcomesPage: 1 2 3 Related medicine news :1
