a. Based on the eight Agency for Healthcare Research and Quality (AHRQ) Prevention Quality Indicators (PQIs) for angina, asthma, congestive heart failure, diabetes, and hypertension. 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 coding changes to the International Classification of Diseases, 9th Revision (ICD-9-CM).

b. 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.

Key: SE: standard error.
