Coronary artery bypass graft (CABG) mortality rate (number of deaths per 1,000 CABG procedures)

Measure Source

Agency for Healthcare Research and Quality (AHRQ) Inpatient Quality Indicators (IQI).


1.53 Deaths per 1,000 admissions with coronary artery bypass graft (CABG), age 40 and older (excluding obstetric and neonatal admissions and transfers to another hospital), United States, 2001 and 2002.

Data Source

AHRQ, Center for Delivery, Organization, and Markets, Healthcare Cost and Utilization Project (HCUP), Nationwide Inpatient Sample.


Hospital inpatient discharges, age 40 and older, with a coronary artery bypass graft (ICD-9-CM codes of 3610 through 3619) in any procedure field.

Excludes patients transferring to another short-term hospital and obstetric and neonatal admissions.


Number of deaths with a code of CABG in any procedure field.


Rates are adjusted by age, gender, age-gender interactions, and APR-DRG risk of mortality score. When reporting is by age, the adjustment is by gender and APR-DRG risk of mortality score; when reporting is by gender, the adjustment is by age and APR-DRG risk of mortality score.

This table was created using version 2.1, revision 3, of the AHRQ IQI software. This measure is referred to as indicator 12 in the software documentation.

Although not all States participate in the HCUP database, it is weighted to give national estimates using weights based on all U.S. community, non-rehabilitation hospitals in the American Hospital Association Annual Survey of Hospitals.
