HealthGrades Seventh Annual Patient Safety in American Hospitals Study.
Approach to Improving Safety
Setting of Care
This report, the latest in an annual series, uses the Agency for Healthcare Research and Quality's Patient Safety Indicators (PSIs) to estimate the incidence of preventable patient safety events, estimate the attributable morbidity and mortality from such events, and identify hospitals with lower rates of PSIs. It is important to note that prior research has questioned the validity of using PSIs for hospital comparison purposes.
