An RCT of Virtual Teach-to-Goal Versus Brief Instruction for Children With Asthma in Clinics

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. Urban, minority, and underserved youth are disproportionally affected. On Chicago's South Side, one-in-five children have an asthma diagnosis; over half visit an urgent care or emergency department (55%), miss school (51.2%), or require parents to miss work annually due to asthma (56.1%).

Effective self-management is crucial to optimize asthma care and improve outcomes. A key barrier to self-management is the 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. Our team developed a V-TTG intervention for adults with demonstrated efficacy. It remains unknown whether this interactive and adaptive module will be feasible and effective in the pediatric population due to varied developmental levels and parental involvement in care.

Virtual Teach-to-Goal (V-TTG) holds the potential to improve inhaler technique in children; however, because learning theory indicates children and adults learn differently, the same learning module cannot be utilized. We have already constructed V-TTG for children with feedback from children with asthma, parents, and healthcare professionals. The learning module is tailored for age by using developmentally and age-appropriate vocabulary, concepts, format, and pacing.
