Abstract

We examined trends in hospitalizations for asthma from 1967 to 1987 among members of a large health maintenance organization. During this time asthma discharges increased significantly among children, and especially among boys under the age of 5 years. Ninety-five percent of the increase in discharges among boys was explained by a corresponding increase in the number of boys who were hospitalized. Increased readmissions did not account for the rise. Changes in the International Classification of Diseases coding of asthma and diagnostic shift by physicians accounted for only part of the increase. A decline in hospitalizations since 1984 may reflect changes in the management of asthma in the emergency room and not a decline in severe asthma episodes.

      Morbidity and mortality due to asthma have increased in recent years, particularly among children and teenagers [1], suggesting the need for improving both control and prevention measures [2]. Numerous patient characteristics have been found to influence functional impairment and health utilization (emergency room and inpatient admissions) associated with asthma, including age, poverty, gender, psychosocial factors, psychiatric disorders and ethnicity [3–6]. Coexisting medical conditions such as allergic rhinitis and sinusitis have been shown to play a role in determining functional impairment in youth and adults with asthma, but the contribution of comorbid psychiatric conditions has received less attention.
