Results of an asthma education program delivered via telemedicine in rural schools

Asthma morbidity is high in low-income children living in rural US regions, yet few interventions have been designed to decrease the asthma burden in rural populations.

To examine the effect of a school-based asthma education program delivered by telemedicine in children living in an impoverished rural region.

We conducted a cluster randomized trial with rural children 7 to 14 years old by comparing a school-based telemedicine asthma education intervention with usual care. The intervention provided comprehensive asthma education by telemedicine to participants and provided evidence-based treatment recommendations to primary care providers.

Of the 393 enrolled children, median age was 9.6 years, 81% were African American, and 47% lived in households with an annual income less than $14,999. At enrollment, 88% of children reported uncontrolled asthma symptoms. At the end of the intervention, there were no statistically significant differences in reported symptom-free days (primary outcome) for the intervention or usual-care group. Participants in the intervention group reported significantly higher use of peak flow meters to monitor asthma and reported taking their asthma medications as prescribed more frequently compared with the usual-care group. There were no changes in other outcome measures, including quality of life, self-efficacy, asthma knowledge, or lung function, between groups.

Although there was some evidence of behavior change among intervention participants, these changes were inadequate to overcome the significant morbidity experienced by this highly symptomatic rural impoverished population. Future interventions should be designed with a multifaceted approach that considers caregiver engagement, distance barriers, and inadequate access to asthma providers in rural regions.
