Inpatient Quality Indicators Overview

Inpatient Quality Indicators Overview
The Inpatient Quality Indicators (IQIs) are a set of measures that provide a perspective on hospital quality of care using hospital administrative data. These indicators reflect quality of care inside hospitals and include inpatient mortality for certain procedures and medical conditions; utilization of procedures for which there are questions of overuse, underuse, and misuse; and volume of procedures for which there is some evidence that a higher volume of procedures is associated with lower mortality.

The IQIs are a software tool distributed free by the Agency for Healthcare Research and Quality (AHRQ). The software can be used to help hospitals identify potential problem areas that might need further study and which can provide an indirect measure of inhospital quality of care. The IQI software programs can be applied to any hospital inpatient administrative data. These data are readily available and relatively inexpensive to use.

The IQIs are the second in the set of AHRQ Quality Indicators (QIs) developed by investigators at Stanford University and the University of California, under a contract with AHRQ.

The AHRQ QIs expanded the original Quality Healthcare Cost and Utilization Project (HCUP) QIs. The Prevention Quality Indicators, the first set of AHRQ QIs, were released in November 2001. The IQIs were released of in May 2002. The third set, the Patient Safety Indicators, were released in March 2003. In February 2006, the fourth QI module, the Pediatric Quality Indicators, was added while the pediatric population was removed from the other modules.

IQI Facts
Inpatient Quality Indicators:
Can be used to help hospitals identify potential problem areas that might need further study.
Provide the opportunity to assess quality of care inside the hospital using administrative data found in the typical discharge record.
Include 15 mortality indicators for conditions or procedures for which mortality can vary from hospital to hospital.
Include 11 utilization indicators for procedures for which utilization varies across hospitals or geographic areas.
Include 6 volume indicators for procedures for which outcomes may be related to the volume of those procedures performed.
Are publicly available without cost.
Are available for download.
