(PHILADELPHIA) -- Researchers at the University of Pennsylvanias School of Medicine have found that hospitals with high and low performance on Medicare quality measures had little difference in the rate of death for three common conditions at the hospitals, indicating that the performance measures may not accurately reflect patient outcomes. Senior author Rachel M. Werner, MD, PhD, Assistant Professor of Medicine at the University of Pennsylvania, Core Investigator with the Center for Health Equity Research and Promotion at the Philadelphia Veterans Affairs Medical Center, and colleague Eric Bradlow, PhD, Professor of Marketing and Statistics at the University of Pennsylvanias Wharton School report their findings in the December 13th issue of JAMA.
In the United States, quality of care delivered in hospitals is often variable. Because it is assumed that measuring quality of care is a key component in improving care, quality measures have an increasingly prominent role in quality improvement, according to background information in the article. These measures can provide an incentive to improve quality of the care delivered and to influence consumer choice of hospitals and health care plans. While some research has documented an association between higher adherence to care guidelines and better outcomes of patients who receive that care, to date there has been limited evidence demonstrating that hospitals that perform better on process measures also have better overall quality.
"What we would like is a kind of Consumer Reports for hospitals so that patients can find out which hospitals are better and then go to these hospitals," said Werner. "Medicare has taken an important step toward that goal by publishing hospital performance in all acute care hospitals in the United States on their website, Hospital Compare."
This study was conducted to determine whether these quality measures are correlated with and predictive of hospitals risk-adjusted death
