AHRQ - Inpatient Quality Indicators (IQIs)

Area-Level (Statewide, County) for California

The Agency for Healthcare Research and Quality (AHRQ) has developed four types of Quality Indicators (QIs), measures of healthcare quality, that make use of hospital inpatient discharge data.

Inpatient Quality Indicators (IQIs) are measures that represent hospitalization rates for four medical procedures for which there could be possible over- or under-use and for which utilization varies across hospitals or geographic areas. High or low rates, by themselves, do not represent poor quality of care. Instead, the information is intended to inform consumers about local practice patterns or identify potential problem areas that might need further study.

Area-Level (Statewide, County) hospitalization rates are provided for the following IQI measures:

  • IQI #26 Coronary Artery Bypass Graft (CABG) (heart bypass surgery)
  • IQI #27 Percutaneous Coronary Intervention (PCI) (widening of a narrowed or blocked artery in the heart using a device inserted in the blood vessel)
  • IQI #28 Hysterectomy (the surgical removal of the uterus or womb)
  • IQI #29 Laminectomy (removal of part of a vertebrae) or Spinal Fusion (back surgery - joining together of two or more vertebrae)

OSHPD views the area-level indicators as useful starting points for examining healthcare quality, but does not regard them as definitive measures of quality. For information about how the indicators are calculated, including technical details about each of the IQIs, visit the AHRQ Website.
