Background:
Pediatric asthma is among the most common health conditions and disproportionately impacts Black and Latino children. Gaps in asthma care exist and may contribute to racial and ethnic inequities. The Rhode Island Asthma Integrated Response (RI-AIR) program was developed to address current limitations in care. The aims of the RI-AIR Hybrid Type II effectiveness-implementation trial were to: a) simultaneously evaluate the effectiveness of RI-AIR on individual-level and community-level outcomes; b) evaluate implementation strategies used to increase uptake of RI-AIR. In this manuscript, we outline the design and methods used to implement RI-AIR.
Methods:
School-based areas (polygons) with the highest asthma-related urgent healthcare utilization in Greater Providence, R.I., were identified using geospatial mapping. Families with eligible children (2-12 years) living in one of the polygons received evidence-based school- and/or home-based asthma management interventions, based on asthma control level. School-based interventions included child and caregiver education programs and school staff trainings. Home-based interventions included individualized asthma education, home-environmental assessments, and strategies and supplies for trigger remediation. Implementation strategies included engaging school nurse teachers as champions, tailoring interventions to school preferences, and engaging families for input.
Results:
A total of 6420 children were screened throughout the study period, 811 were identified as eligible, and 433 children were enrolled between November 2018 and December 2021.
Conclusions:
Effective implementation of pediatric asthma interventions is essential to decrease health inequities and improve asthma management. The RI-AIR study serves as an example of a multi-level intervention to improve outcomes and reduce disparities in pediatric chronic disease.

Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
