Pneumonia mortality rate (number of deaths per 1,000 discharges for pneumonia)

Measure Source

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


1.98 Deaths per 1,000 admissions with pneumonia as principal diagnosis, age 18 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.


All discharges age 18 and older with principal diagnosis code of pneumonia. Exclude patients transferring to another short-term hospital and obstetric and neonatal admissions.


Number of deaths with a principal diagnosis code of pneumonia.


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. See Guide to Inpatient Quality Indicators at for a discussion of this measure, including a complete list of ICD-9-CM codes.

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 20 in the software documentation. More information about the AHRQ Quality Indicators is available at
