HealthGrades Study: New Hospital Ratings Show Wide 'Quality Chasm'; Eighth Annual HealthGrades Hospital Quality in America Study Released; 2006 Ratings of 5,000 Hospitals Launched at HealthGrades.Com

Posted on: Monday, 17 October 2005, 09:00 CDT

65% Lower Chance of Dying at Five-Star Hospitals

Compared with One-Star Hospitals; Better Outcomes Associated with

Higher Volume and More Specialists in Intensive Care,

Confirming Leapfrog Standard

A typical patient has a 65 percent lower chance of dying at the nation's highest-rated hospitals compared with the lowest-rated hospitals, in 18 common procedures and diagnoses, according to a large-scale study released today by HealthGrades (Nasdaq: HGRD). That "quality chasm," the HealthGrades study shows, is growing, as the nation's best-performing hospitals lowered their mortality rates 45 percent faster than the poorest-performing hospitals over the same time period.

The findings are part of the eighth annual HealthGrades Hospital Quality in America Study, which analyzes 37 million Medicare hospitalization records, from the years 2002 through 2004, to rate the quality of care at each of the nation's more than 5,000 nonfederal hospitals. The hospital ratings, for 28 procedures and diagnoses at each facility, are listed free of charge for consumers at www.healthgrades.com.

"There is real reason to celebrate in this year's study of quality at America's hospitals," said Samantha Collier, MD, the primary author of the study and the vice president of medical affairs at HealthGrades, the leading healthcare ratings company. "Overall, mortality rates are declining at our nation's hospitals. However, there's still a lot of work to be done because our findings support that we're not making much headway in closing the 'quality chasm' between the best and worst hospitals. If all hospitals performed as well as the highest-rated hospitals, more than a quarter million lives would have been saved over the past three years."

Overall mortality rates improved 12 percent, the study shows, with some of the better outcomes associated with higher hospital volumes and higher numbers of physicians who specialize in critically ill patients, called intensivists, staffing intensive care units (ICUs).

The annual HealthGrades study rates each nonfederal hospital with a one-, three- or five-star rating indicating poor, average or excellent outcomes in each of 28 medical categories. Taken together, the ratings produce the following findings:

-- The nation's in-hospital risk-adjusted mortality rate

improved, on average, 12 percent from 2002 to 2004. But the

degree of improvement varied widely by procedure and diagnosis

studied.

-- Five-star-rated hospitals had significantly lower

risk-adjusted mortality rates across all three years studied

and improved 21 percent more than the U.S. hospital average

and 45 percent more than 1-star-rated hospitals.

-- A typical patient would have, on average, a 65 percent lower

chance of dying in a 5-star-rated hospital compared to a

1-star-rated hospital, and a 45 percent lower chance of dying

in a 5-star-rated hospital compared to the U.S. hospital

average.

-- If all hospitals performed at the level of a 5-star-rated

hospital across 18 of the procedures and diagnoses studied,

273,137 Medicare lives could have potentially been saved from

2002 through 2004. Fifty percent of the potentially

preventable deaths were associated with just four diagnoses:

Heart Failure, Community Acquired Pneumonia, Sepsis and

Respiratory Failure.

-- Five-star-rated hospitals have higher volumes and higher rates

of intensivists staffing ICUs associated with three severe

illnesses. Higher volumes are associated with better outcomes

for Abdominal Aortic Aneurysm Repair. Higher rate of ICUs

staffed with intensivists is associated with better outcomes

for Diabetic Acidosis and Coma and Pulmonary Embolism. ICU

intensivist staffing is an indicator of quality promoted by

the Leapfrog Group, and the data used in this study is part of

the Leapfrog Group Survey.

Effective in 2004, drug eluting stents were coded with their own ICD-9 code, and this code was one of the predictors used to create the expected value. This code decreased the "expected" for 2004 only, resulting in a larger ratio for that year.
