A community-based asthma program: Study design and methods of RVA Breathes

Abstract

Disparities in pediatric asthma morbidity and healthcare utilization exist on the basis of race, ethnicity, environment, and income; interventions are needed to address these inequities. The following protocol describes an evidence-based intervention, RVA Breathes, designed to coordinate pediatric asthma care across family, home, community, and medical sectors. Community stakeholder feedback was utilized to refine the intervention specifically for the Richmond, Virginia community. The aims of this study are to assess the effect of RVA Breathes on asthma-related healthcare utilization, as well as secondary outcomes of asthma control, asthma symptoms, and quality of life. We will enroll 300 elementary school children from the Richmond City Public School system. Participants will be between the ages of 5-11, have a diagnosis of asthma, and have had an asthma exacerbation (as indicated by an asthma-related ED visit, hospitalization, unscheduled PCP visit, or use of systemic steroids) in the last two years. Participants will be randomized to one of three groups: asthma education + home environment remediation + school intervention, asthma education + home environment remediation, or a comparator condition. Data will be collected across one baseline research visit, four intervention sessions, and four follow-up research visits over the course of 18 months. A General Linear Mixed Model (GLMM) will be used to test primary aims. We expect the findings will provide support for coordination of asthma care across sectors. Further, we hope RVA Breathes will serve as a model of community-based pediatric asthma care.
