Outcomes evaluation of a comprehensive intervention program for asthmatic children enrolled in Medicaid

Objectives. To evaluate health care and financial outcomes in a population of Medicaid-insured asthmatic children after a comprehensive asthma interve ntion program. Design. Controlled clinical trial. Setting. Pediatric allergy clinic in an urban, tertiary care children's hos pital. Subjects. Eighty children, 2 to 16 years old, with a history of frequent us e of emergent health care services for asthma. Intervention. Children in the intervention group received asthma education and medical treatment in the setting of a tertiary care pediatric allergy c linic. An asthma outreach nurse maintained monthly contact with the familie s enrolled in the intervention group. Outcome Measures. Emergency department (ED) visits, hospitalizations, and h ealth care charges per patient in the year after enrollment. Results. Baseline demographics did not differ significantly between the 2 g roups. In the year before the study, there were no significant differences between intervention and control children in ED visits (mean, 3.5 per patie nt), hospitalizations (mean, .6 per patient) or health care charges ($2969 per patient). During the study year, ED visits decreased to a mean of 1.7 p er patient in the intervention group and 2.4 in controls, while hospitaliza tions decreased to a mean of .2 per patient in the intervention group and . 5 in the controls. Average asthma health care charges decreased by $721/chi ld/year in the intervention group and by $178/patient/year in the control g roup. Conclusions. A comprehensive asthma intervention program for Medicaid-insur ed asthmatic children can significantly improve health outcomes while reduc ing health care costs.
