HealthGrades patient safety study shows increase in hospital incidents, gaps among state, hospitals…Incidents cost Medicare $9.3 billion over 3 years; patients at top-performing hospitals have 43 percent lower incidence of medical errors compared to worst; Minnesota, ranked #1, is success story

Patient safety incidents in American hospitals grew from 1.18 million to 1.24 million among the 40 million hospitalizations covered under the Medicare program, and incidents varied widely from state to state, and among the best and worst hospitals, according to a study released today by HealthGrades, the leading healthcare ratings company.

"Overall we see the number of patient safety incidents in American hospitals continuing to increase, at an enormous cost, and we still see a large gap between the incidence rates at the nation's top-performing and worst-performing hospitals," said Dr. Samantha Collier, HealthGrades vice president of medical affairs. "But we do find the results of serious attempts to grapple with this issue in the success of top-performing hospitals and in progressive states like Minnesota."

The third HealthGrades Patient Safety in American Hospitals study, the largest annual study of its kind, also finds:

Differences Among Hospitals

Medicare patients going to hospitals ranked among the top 15 percent in terms of patient safety incidents had, on average, 43 percent lower incidence of patient safety incidents compared to bottom-ranked hospitals

If all hospitals performed at the level of the top 15 percent, 280,134 fewer patient safety incidents and 44,153 fewer deaths among Medicare patients would have occurred, saving $2.45 billion during the years 2002 through 2004

Of the 304,702 deaths that occurred among patients who developed one or more patient safety incidents, 250,246 were potentially preventable

Medicare beneficiaries experiencing one or more patient safety incidents had a one-in-four chance of dying during their hospitalization, a rate that is unchanged since HealthGrades' first study

Number and Cost of Patient Safety Incidents

Approximately 1.24 million total patient safety incidents occurred among the nearly 40 million hospitals under the Medicare program over the years 2002, 2003 and 2004. That compares with 1.18 million over the previous three-year period, and 1.14 million over the years 2000, 2001 and 2002

These patient safety incidents were associated with $9.3 billion in excess costs during the years 2002 to 2004

State Rankings and Differences

Wide and highly significant gaps in patient safety incidence levels were discovered between the top-performing states and those at the bottom over the years 2002, 2003 and 2004

Minnesota, Wisconsin, Iowa, Michigan and Kansas ranked as the top states for hospital patient safety

New Jersey, New York, Nevada, Tennessee and the District of Columbia ranked last

Medicare patients in the best state, Minnesota, had an almost 30 percent overall lower relative risk of developing one or more of the patient safety incidents, compared with the worst state, New Jersey

Trends in Patient Safety Incidents

The patient safety incidents with the highest prevalence continue to be failure to rescue, decubitus ulcer and post-operative sepsis

Failure to rescue improved over the study period, while post-operative sepsis worsened by almost 25 percent

State Rankings The study ranked the nation's states in terms of the prevalence of patient safety incidents in each states' hospitals and are grouped as performing better, as expected, or worse than expected to a statistically significant degree:

Minnesota ranked first overall in this year's state ranking by HealthGrades, and in this state are progressive efforts to improve patient safety. While twenty-five states now have some form of mandatory reporting of medical errors, Minnesota was the first state, in 2003, to legislate mandatory public reporting, using guidelines from the National Quality Forum. Minnesota's Safest in America program allows competitive hospitals to work together to share data, highlight best practices and implement evidence-based, community-tested solutions. Of the eight non-children's hospital systems participating in the Safest in America collaborative, four have hospitals that ranked in the top 15 percent in the national according to this study.

"Two of the patient-safety incidents found in the study to be among the most prevalent are failure to rescue and post-operative sepsis," continued Dr. Collier. "Failure to rescue is the inability to save a hospitalized patient's life when that patient has acquired in the hospital a complication, such as when a patient admitted for a total knee replacement develops pneumonia and dies. An example of post-operative sepsis is when an otherwise previously healthy patient is admitted for a total knee replacement and develops an overwhelming bacterial bloodstream infection requiring potent antibiotics and other treatment resulting in a longer hospital stay and possibly death. Both of these are areas of focus for the most progressive hospitals, who have developed successful ways of minimizing or eliminating deaths from these incidents."

Distinguished Hospital Awards and Findings
Based on the study, HealthGrades identified 238 hospitals reaching the top 15 percent in the nation in terms of patient safety, qualifying them to receive the HealthGrades Distinguished Hospital Award for Patient Safety. The award was designed to highlight hospitals with the best records of patient safety in the nation and to encourage consumers to research their local hospitals' patient safety records before undergoing a procedure. As a category, Medicare patients at Distinguished Hospitals experienced patient safety incidents, on average, 43.27 percent less often than patients at the bottom 15 percent of all hospitals.
