A Randomized Clinical Trial Evaluating the Effectiveness of Virtual Teach-to-Goal Education vs. Brief Intervention for Children

Asthma is the most common chronic childhood condition and has significant adverse consequences. One in 12 United States children has asthma, resulting in 13.4 million missed school days, 1 million emergency department visits, and 140,000 hospitalizations annually.

A key barrier to self-management of asthma is improper use of respiratory inhalers, which limits disease control. Better inhaler technique is associated with improved asthma outcomes for children. Assessment and education of inhaler technique are recommended at all healthcare encounters, however it is limited in practice because it is resource intensive (both personnel and time) and lacks fidelity. Thus, low-resource interventions that accurately teach inhaler skills are needed to impact pediatric asthma outcomes.

Teach-to-Goal (TTG) is a patient-centered strategy that uses tailored rounds of teaching and assessments to ensure mastery of inhaler technique. Studies show it is effective but resource intensive. A "virtual TTG" (V-TTG) intervention represents an opportunity to deliver inhaler technique education with a high-fidelity, low-resource, and feasible strategy. The module utilizes innovative learning technology with video demonstrations and assessment questions to tailor education to each user; the cycles of assessment and education continues until satisfactory mastery is achieved.

This study evaluates the comparative effectiveness of this high-fidelity, low-resource, and feasible model (V-TTG) versus a standardized brief intervention that mimics usual care to deliver tailored inhaler technique education to children with severe asthma via a randomized clinical trial.
