State Denominator

Same as national.

State Numerator

Same as national.

Comments

Consistent with the AHRQ PQI software, hypertension must be the principal diagnosis. The following are excluded: admissions with kidney disease with dialysis access procedures, admissions with cardiac procedures, and transfers from other institutions.

Rates are adjusted by age and gender using the total U.S. resident 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.

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.

The SID disparities analysis file is designed to provide national estimates on disparities using weighted records from a sample of hospitals from the following 31 States: Arizona, Arkansas, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Kansas, Kentucky, Maine, Maryland, Massachusetts, Michigan, Missouri, Nevada, New Hampshire, New Jersey, New York, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Utah, Virginia, Vermont, Wisconsin, and Wyoming.
