title: Severity of illness and ambulatory care-sensitive conditions.
abstract: This study describes how severity of illness may refine the definition of ambulatory care-sensitive conditions, or ACSCs. Hospital discharge abstract data from Philadelphia were combined with census data to develop population-based adjusted rates of hospitalization for diabetes and asthma, two ACSCs. By stratifying ACSC hospitalization by severity of illness, variations were observed by age, race, and gender. Minority groups may be at higher risk for less access to outpatient primary care and were observed to have higher rates of more severely ill, Stage 3 hospitalization. Geographic map displays indicated wide ranges of age-sex-adjusted rates for high-severity hospitalization in the five-county Philadelphia region. This refined ACSC measure may help to identify specific groups and clinical conditions within a population to assist health care planners estimate health care resources such as facilities, manpower, and programs, as well as to evaluate their outcomes.
