Background: 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., Objective: To examine the effectiveness of an in-home asthma intervention program for children and adults in Connecticut, we conducted a panel study to analyze quality-of-life indicators for asthmatic patients and the cost-benefit relationship in preventive care versus acute care., Methods: 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., Results: Twenty percent of participants in the program met the criteria for well-controlled asthma, 16% for not well-controlled asthma, and 64% for very poorly controlled asthma. At 6 months follow-up, the mean number of unscheduled acute care visits, days absent from school/work due to asthma, and times rescue inhaler used in the past week decreased by 87%, 82%, and 74%, respectively, whereas the mean number of symptom-free days increased by 27% compared to the initial visit. Furthermore, the percent of participants with very poorly controlled asthma decreased from 64% at initial visit to 13% at 6 months follow-up. All changes were statistically significant at p < 0.05. A net savings of $26,720 per 100 participants was estimated at 6 months follow-up due to decreases in unscheduled acute care visits for adults and children., Conclusion: Significant improvement in quality-of-life and decreases in healthcare resource utilization and costs were found after implementation of the AIRS program in Connecticut.
