Quality-of-Life and Cost–Benefit Analysis of a Home Environmental Assessment Program in Connecticut

The National Asthma Education Prevention Program's (NAEPP) Expert Panel Report 3 (EPR3) guidelines have stressed the need for environmental control measures for asthma, but there is limited evidence of their efficacy. To examine the effectiveness of an in-home asthma intervention program for children and adults in Connecticut, the Connecticut Department of Health conducted a panel study to analyze quality-of-life indicators for asthmatic patients and the cost–benefit relationship in preventive care versus acute care.

The Asthma Indoor Reduction Strategies (AIRS) program was developed to reduce acute asthma episodes and improve asthma control through patient education and a home environmental assessment. Follow-up was conducted at 2-week, 3-month, and 6-month intervals. Measured quality-of-life indicators included number of unscheduled acute care visits, days absent from school/work due to asthma, times rescue inhaler used, and number of symptom-free days. Repeated measures analysis of variance (ANOVA) was used to determine whether significant differences exist in quality-of-life indicators at follow-up compared to that at the initial visit. Cost–benefit analysis was conducted by tabulating costs associated with physician office visits and emergency department (ED) visits due to asthma for children and adults separately.
