Description

During the formative evaluation (Phase 1), the researchers will engage community stakeholders (primary caregivers of children with asthma, school personnel, asthma healthcare providers) to help identify, adapt and finalize strategies for PR-AIR implementation. The Consolidated Framework for Implementation Research (CFIR) will be used to identify barriers and facilitators of low-intensity and high-intensity implementation approaches, the Adaptome to guide intervention adaptation to the context of PR, and the CFIR-ERIC matching tool to identify strategies to support but low- and high-intensity implementation packages. Fifteen stakeholders will complete in-depth interviews early in Phase 1, and 16 will participate in two focus groups at the end of Phase 1 prior to the transition to Phase 2, in preparation for trial implementation. A collaborative of community stakeholders will be convened (the PR-AIR CC) to provide input throughout both phases of the trial.

In Phase 2 (Years 2-4) 480 urban children will be enrolled, ages 2-12 (expected retention for full protocol, n = 400) with asthma across 12 areas in San Juan with high asthma burden. Randomization is at the level of targeted geographic area, and data will be collected from groups in each of these areas over time. Individual-level (asthma control, QOL) and community-specific (ED use/hospitalizations, school absence) effectiveness outcomes will be evaluated. All families will participate in both a control (in our case, baseline period for the community indicators) and intervention (active trial). Each target area will begin with a low-intensity (virtual) implementation phase, and transition to a high-intensity implementation phase mid-year. Families enrolled in the first 5 months of the school year will receive the low-intensity intervention package, and those enrolled in the last 5 months of the school year will receive the high-intensity intervention package. Input will be collected throughout each year from community stakeholders about the trial, through in-depth interviews and surveys. Reach, Adoption, Implementation, and Maintenance will be measured using a mixed-methods approach at the end of each trial year (years 2 - 4). Repeated assessments will measure individual-level effectiveness outcomes (asthma control, QOL) at time points linked to the start of intervention participation; at enrollment, end of treatment (EOT; 1 - 2 months after baseline, depending on intervention assignment), and every 3 months for 1 year.
