|15 Highest Performing Hospital Systems Improve Quality, Have Lower 30-Day Mortality Rate
ANN ARBOR, Mich., Jan. 17, 2012 -- Thomson Reuters today released its fourth annual study identifying the top U.S. health systems based on balanced system-wide clinical performance.
The Thomson Reuters 15 Top Health Systems study culled data from more than 300 organizations and singled out 15 hospital systems that achieved superior clinical outcomes based on a composite score of eight measures of quality, patient perception of care and efficiency.
"This year we are seeing stronger system-wide performance and increased rates of improvement, particularly among the 15 Top Health Systems award winners. Health system performance is beginning to reflect aspirations to provide more consistent outcomes across communities served," said Jean Chenoweth, senior vice president for performance improvement and 100 Top Hospitals® program at Thomson Reuters. "Healthcare reform appears to have stimulated the increased rate of improvement at the system level."
Among the key findings in the study were the following:
The study divides the top health systems into three comparison groups based on total operating expense of the member hospitals. The winners are as follows:
- Lower 30-Day Mortality Rates: 15 Top Health Systems held post-discharge 30 day mortality rates steady, while peer health systems demonstrated a significant increase in post discharge mortality.
- Better Survival Rates: Winning hospitals had 17 percent fewer deaths than expected considering patient severity, while non-winning hospitals had 4 percent more deaths than expected.
- Fewer Complications: Patients of the winning health systems had 19 percent fewer complications.
- Shorter Hospital Stays: Patients treated in the winning system hospitals have a median average length of stay of 4.7 days, nearly half a day shorter than their peers' median of 5.1 days.
- Better Patient Safety and Core Measure Adherence: Top health systems had 23 percent fewer adverse patient safety events than expected and had better adherence to core measures of care than their peers.
U.S. health systems with two or more short-term, general, non-federal hospitals; cardiac and orthopedic hospitals; and critical access hospitals were assessed in the study. Researchers looked at eight metrics that gauge clinical quality and efficiency: mortality, medical complications, patient safety, average length of stay, 30-day mortality rate, 30-day readmission rate, adherence to clinical standards of care (evidence-based core measures published by the Centers for Medicare and Medicaid Services), and HCAHPS patient survey score (part of a national initiative sponsored by the United States Department of Health and Human Services to measure the quality of care in hospitals).
