Characteristics of Hospitalization for Asthma Among Persons Less than 35 Years of Age in Chicago

Abstract

Mortality from asthma in Chicago is among the highest in the nation for 5-34-year-olds. Data for all hospitalizations among Chicago residents less than 35 years of age were examined to define characteristics that may be contributing to morbidity and mortality from asthma. From 1987 through 1989, the average annual age-adjusted hospitalization rate among persons less than 35 years of age in Chicago was 3.57 per 1000 persons. There were significant associations of community hospitalization rate with median income (r = -0.61, p < 0.001) and with proportion of community asthma hospitalizations using Medicaid, Medicare, or self-payment (r = 0.69, p < 0.001). Among 18-34-year-old men, asthma hospitalization rates for Medicaid recipients were 17.4-34.1-fold higher than among men using other forms of insurance. Asthma admissions using Medicaid, Medicare, or self-payment were more likely than those using other forms of insurance to present through the emergency department (79.3% and 66.4%, respectively, p < 0.001) and be discharged against medical advice (1.8% vs. 0.7%, respectively, p < 0.001). These data suggest that differential access to or utilization of health care may be contributing to asthma morbidity in Chicago.
