SMART-SBAT: Transforming Pediatric Asthma Care Through School-Based Single-Inhaler Therapy

Despite well-established asthma guidelines and effective preventive medications, many children with persistent asthma do not receive recommended daily anti-inflammatory therapy, and follow-up care with guideline-based step-up adjustments and specialty evaluation is inconsistent. Over a decade ago, in partnership with the Rochester City School District, the investigators co-developed the School-Based Asthma Therapy (SBAT) program to enhance adherence to guideline-based treatment through school-based directly observed therapy (DOT) of preventive medications. Research demonstrated reductions in exacerbations and asthma symptoms, and key stakeholders strongly supported program continuation and scale-up. However, despite its clinical impact, SBAT has not been broadly implemented or sustained outside research trials, and some children continued to have suboptimal asthma control. Recent guideline endorsement of single maintenance and reliever therapy (SMART) offers a timely opportunity to accelerate translation of evidence-based asthma care into real-world practice. SMART simplifies asthma management, improves symptom control, and enables rapid intensification of anti-inflammatory therapy when control remains poor, yet uptake in routine pediatric care remains limited. To address this critical implementation gap and advance pediatric asthma care, the investigators plan to initiate SMART-SBAT, integrating a single ICS-formoterol inhaler at school for both DOT and symptom-driven use. Because school nurses already manage reliever medications, replacing separate controller and reliever inhalers with a single ICS-formoterol inhaler simplifies medication management, facilitates rapid adoption of SMART within existing school health workflows, and enables a "natural" step-up in therapy when symptoms occur. By embedding guideline-recommended SMART delivery in schools, SMART-SBAT provides a pragmatic pathway to accelerate real-world implementation at scale. SMART-SBAT also provides a platform to evaluate treatment response under conditions of reliable medication exposure, including differential effects by asthma phenotype and environmental context, while facilitating specialty evaluation for children with ongoing poor control. Using a pragmatic Type 1 hybrid stepped-wedge trial, the investigators will evaluate effectiveness while simultaneously assessing implementation processes relevant to real-world delivery. Approximately 330 caregivers in SMART-SBAT and usual care schools will be enrolled for longitudinal surveys and medical record reviews to assess outcomes (primary outcome = urgent care and emergency visits for asthma over 12 months). Explanatory mixed-methods analyses will assess reach, fidelity, dose, and adaptations, and evaluate whether baseline clinical characteristics, environmental exposures, and social context modify response to SMART-SBAT. Findings will inform foundational components of a SMART-SBAT toolkit to support broader dissemination. By accelerating uptake of simplified, guideline-based therapy within routine school systems and enabling evaluation beyond adherence barriers, SMART-SBAT aims to reduce exacerbations, improve asthma control, and generate actionable evidence for scalable, high-quality asthma care.
