Agency for Healthcare Research and Quality (AHRQ) Quality Indicators Home

The Agency for Healthcare Research and Quality (AHRQ) Quality Indicators (QIs) are measures of health care quality that make use of readily available hospital inpatient administrative data.

The AHRQ QIs consist of four modules measuring various aspects of quality:

Prevention QIs identify hospital admissions that evidence suggests could have been avoided, at least in part, through high-quality outpatient care. Download PQI Module.

Inpatient QIs reflect quality of care inside hospitals including inpatient mortality for medical conditions and surgical procedures. Download IQI Module.

Patient Safety Indicators also reflect quality of care inside hospitals, but focus on potentially avoidable complications and iatrogenic events. Download PSI Module.

Pediatric QIs both reflect quality of care inside hospitals and identify potentially avoidable hospitalizations among children. Download PedQI Module.


Software and user guides for all four modules are available to assist users in applying the Quality Indicators to their own data.
