Comparative Effectiveness of Multi Versus Single Intervention Allergen Reduction Strategies on Asthma Morbidity
Tulane University
Summary
The Allergen Reduction and Child Health Study (ARCHS) is a 12-month, two group randomized control trial of children with asthma and who are exposed to cockroaches. Children ages 5 - 17 living in the Greater New Orleans area will be recruited from a variety of clinic and community settings. The overall goal of the study is to improve patient-centered asthma outcomes (asthma symptom days, health care utilization, asthma control and quality of life) by targeting one key allergen - cockroach exposure in the child's home. The investigators propose a simple intervention of insecticidal bait that is low cost, simple to implement, and which is lower toxicity than other forms of pest control. The reduction in the number of cockroaches in the home is an environmental outcome that is patient-centered and is likely to add to its acceptance by families of children with asthma.
Description
Background and Significance: Asthma is a serious, complex, and highly prevalent childhood respiratory disorder leading to inflammation and narrowing of the airways. If uncontrolled it negatively impacts long-term lung function. An estimated 6.2 million, 1 in 12, U.S. children have asthma and asthma outcome disparities are pervasive. An important contributor to asthma disparities is greater exposure to asthma triggering allergens. The proposed study addresses an evidence gap related to the most effective way to reduce exposure to asthma triggers in the home. Study Aims: There are three specifi…
