Pediatric heart surgery mortality rate (number of deaths per 1,000 heart surgeries in patients under age 18 years)

Measure Source

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


1.51 Deaths per 1,000 pediatric heart surgery admissions, patients age less than 18 years (excluding obstetric admission; patients with transcatheter interventions as single cardiac procedures, performed without bypass but with catheterization; patients with septal defects as single cardiac procedures without bypass; heart transplant; premature infants with patent ductus arteriosus (PDA) closure as only cardiac procedure; and age less than 30 days with PDA closure as only cardiac procedure; 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 with either a procedure for (1) specified heart surgery in any field or (2) any heart surgery and diagnosis of hypoplastic left heart syndrome in any field, age less than 18 years.

Excludes patients transferring to another short-term hospital; obstetric admission; patients who underwent PDA ligation as a single cardiac procedure; patients with prosthetic closures of atrial septal defects or ventricular septal defects or atrial septal enlargement without concomitant use of cardiopulmonary bypass; patients with PDA closure as a single cardiac procedure with concomitant cardiac catheterization; patients with occlusion of thoracic vessel without congenital heart defect.


Number of deaths with a code of pediatric heart surgery 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.

Although not all States participate in the HCUP database, the Nationwide Inpatient Sample 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.

This table was created using version 2.1, revision 3, of the AHRQ IQI software. This measure is referred to as indicator 10 in the software documentation. More information about the AHRQ Quality Indicators is available at

Abdominal aortic aneurysm (AAA) repair mortality rate (number of deaths per 1,000 AAA repairs). Hospital admissions for congestive heart failure (CHF).
