National Denominator

U.S. civilian population ages 2-17 or age 18 and over, as appropriate.

National Numerator

Subset of the denominator with an emergency department asthma visit.

Comments

Consistent with the AHRQ Quality Indicators software, asthma must be the principal diagnosis and the following cases are excluded: admissions with cystic fibrosis or anomalies of the respiratory system, transfers from other institutions, and obstetric admissions.

Rates are adjusted by age and gender using the total U.S. population for 2000 as the U.S. standard population; when reporting is by age, the adjustment is by gender only; when reporting is by gender, the adjustment is by age only.

Although not all States participate in the HCUP database, NIS is weighted to give national estimates using weights based on all U.S. community, nonrehabilitation hospitals in the American Hospital Association Annual Survey Database.

State Data Source

AHRQ, CDOM, HCUP, State Inpatient Databases (SID).

State Denominator

Same as national.

State Numerator

Same as national.

Comments

Based on the 11 AHRQ PQIs for angina, asthma, bacterial pneumonia, congestive heart failure, dehydration, diabetes, hypertension, and urinary tract infection. For consistency of longitudinal reporting, the modified overall composite does not include AHRQ PQI 5 for chronic obstructive pulmonary disease because it is affected by International Classification of Diseases, Ninth Revision coding changes.

Rates are adjusted by age and gender using the total 2000 U.S. standard population.

Although not all States participate in the HCUP database, NIS is weighted to give national estimates using weights based on all U.S. community, nonrehabilitation hospitals in the American Hospital Association Annual Survey Database.

SID includes a powerful set of hospital databases from data organizations in participating States. SID contains the universe of the inpatient discharge abstracts in participating States, translated into a uniform format to facilitate multi-State comparisons and analyses. Together, SID encompasses about 90% of all U.S. community hospital discharges. SID contains a core set of clinical and nonclinical information on all patients, regardless of payer, including people covered by Medicare, Medicaid, and private insurance, as well as uninsured people. In addition to the core set of uniform data elements common to all SID, some databases within SID include other elements, such as the patient's race.
