Admissions for perforated appendix to Indian Health Service hospitals per 1,000 population in Indian Health Service areas.

Measure Source

Agency for Healthcare Research and Quality (AHRQ) Prevention Quality Indicators (PQI).

Tables

228 Hospitalizations for perforated appendix per 1,000 hospitalizations with appendicitis in Indian Health Service and Tribal hospitals, 2003.

Data Source

Indian Health Service (IHS), National Patient Information Reporting System (NPIRS).

Denominator

Population in Indian Health Service areas.

Numerator

Subset of the denominator with principal or secondary diagnosis code for perforation or abscess of appendix.

Comments

This measure is adapted from the AHRQ Prevention Quality Indicators where it is referred to as indicator 2. The ICD-9-CM codes used to identify discharges for uncontrolled diabetes are the same as AHRQ Prevention Quality Indicator 2, but the format of NPIRS did not allow for exclusion of transfers.

The numerator includes hospitalizations in IHS Service hospitals and contract hospitals with admissions during 2003. Because of concerns about the quality of the data, hospitalizations from the California and Portland regions are deleted; the denominator is correspondingly reduced.

The total estimates are age adjusted using the total U.S. population for 2000 as the standard population.
