Quantifying Preventive Asthma Care Delivered at Office Visits: The Preventive Asthma Care–Composite Index (PAC-CI)

Abstract

Our objective was to develop a composite index to measure and quantify preventive asthma care delivered in the primary care office. We documented preventive actions used for children with asthma at the time of an office visit and weighted actions based on their intensity to create a composite index. The usefulness of the index was supported by significant correlations with several measures of symptom severity. The composite index also varied by visit type, with the highest scores noted for asthma-related visits, compared to well-child and other illness visits. This composite index has potential use for research and quality improvement efforts.
