The Puerto Rico Asthma Integrated Response Program ("PR-AIR")

The purpose of this study is to adapt and deliver an evidence-based multi-level intervention to reduce asthma disparities, and that promote and improve population health in the high-burden communities of San Juan, Puerto Rico.

The Puerto Rico-Asthma Integrated Response Program (PR-AIR) will be implemented and evaluated to address pediatric asthma disparities in San Juan, PR, an area of high asthma burden. This study unfolds in two phases: In Phase 1, the researchers will collaborate with community stakeholders to identify needs, barriers and facilitators of PR-AIR implementation. Phase 2 consists of an evaluation of low-intensity (virtual) and high-intensity (in-person) methods of PR-AIR implementation outcomes using the RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) framework and a mixed methods approach.

About this study

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.

Treatment and study plan

CASE in person version (High Intensity Package)

Behavioral

Controlling Asthma in Schools Effectively (CASE) is a multi-level school-based asthma management program delivered by a Community Health Worker (CHW) that includes 1) staff training involving education on asthma management in school, 2) child-based asthma management education with an emphasis on control of symptoms in the school setting provided in a group setting during the school day, 3) caregiver education after school involving supporting children's asthma control in the school setting, 4), and provision of an Asthma Action Plan (AAP) to the school for child enrollees.

CASE-V remote version (Low Intensity Package)

Behavioral

CASE-V, the low intensity version of CASE, includes similar child and caregiver-based asthma management education that is provided in a remote format with adaptation to integrate technological feature of Zoom. All CASE-V components (for staff, children, and parents) have been adapted to promote engagement (e.g., use of chat and polling function).

CASE and HARP in person (High Intensity package)

Behavioral

Children with "poorly controlled" asthma will receive both the CASE and HARP programs. HARP is a home-visiting program that includes individualized asthma management education and strategies and supplies for environmental remediation. All 3 visits can be conducted by a CHW. The first includes a "walk-through" to identify triggers. Asthma education and self-management strategies are provided using a structured protocol and low-literacy flip-book (English or Spanish). Referrals and advocacy are offered to address asthma management barriers (e.g., communication with landlord/housing re: code violation). The 2nd and 3rd visits include delivery of supplies (e.g., HEPA vacuum, pest gels, mattress covers), instruction for use, review of AAP, and follow-up on environmental control recommendations provided during the 1st visit.

CASE-V and HARP-V remote version (Low Intensity package)

Behavioral

HARP-V replicates the content delivered in HARP in a remote format. The first session includes a virtual "walk-through" in which the educator uses a structured script and checklist to guide the caregiver through the home and show specific components of the environment (e.g., carpeting, area under the kitchen sink, exhaust fan in bathroom) to identify asthma triggers. Asthma education and self-management strategies are provided using a structured protocol and slide overview based on the HARP flip-book. Supplies for environmental remediation are delivered prior to the 2nd visit. The 2nd and 3rd visit include instruction for use of supplies, review of AAP, and follow-up on recommendations and referrals.

Primary outcomes

  1. Change in Child Asthma Control (Individual Level, ages 2-4 years)

    Time frame: Asthma Control will be measured at baseline, End of Treatment (EOT; 1 - 2 months after baseline, depending on intervention assignment), and every 3 months for 1 year.

    Effectiveness of the intervention on child-level asthma control is measured using the Test for Respiratory and Asthma Control in Kids (TRACK). The TRACK is a 5-item measure assessing asthma symptoms and control in young children by caregiver report. Items assessing frequency of various asthma-related events (e.g., breathing problems, quick-relief medication use, etc.) are rated on a Likert-type scale from Not at all (scored 20) to Extremely (scored 0). Scores < 80 suggest child's asthma is not well controlled.

  2. Change in Child Asthma Control (Individual Level, ages 5-11 years)

    Time frame: Asthma Control will be measured at baseline, End of Treatment (EOT; 1 - 2 months after baseline, depending on intervention assignment), and every 3 months for 1 year.

    Effectiveness of the intervention on child-level asthma control is measured using the Childhood Asthma Control Test (cACT). Children answer 4 questions on a 0-3 scale, and caregivers answer 3 questions on a 0-5 scale related to the frequency child's asthma symptoms in the previous 4 weeks. Lower scores indicate worse symptoms. Scores of 19 or less suggest asthma is not well controlled.

  3. Change in Child Asthma Control (Individual Level; ages 12 and up)

    Time frame: Asthma Control will be measured at baseline, End of Treatment (EOT; 1 - 2 months after baseline, depending on intervention assignment), and every 3 months for 1 year.

    Effectiveness of the intervention on child-level asthma control is measured using the Asthma Control Test. Youth ages 12 and up complete 5-items related to their asthma on Likert-type scales ranging from 1-5, with lower scores indicating more severe symptoms. A cutoff score <19 indicates suboptimal asthma control; scores <=15 suggest poorly controlled asthma.

  4. Health Care Utilization-ED visits (Community Level)

    Time frame: 12 months pre- and post-intervention year

    Health care utilization will be assessed by community-level rates of Emergency Department visits of children within the targeted geographic area. Obtaining utilization rates in this way will help the researchers to assess effectiveness of the intervention on the community level.

  5. Health Care Utilization-Hospitalizations (Community Level)

    Time frame: 12 months pre- and post-intervention year

    Effectiveness of the intervention on the community level. Health care utilization will be assessed by community-level rates of hospitalizations in children within the targeted geographic area.

  6. Health Care Utilization-Urgent Care Visits (Community Level)

    Time frame: 12 months pre- and post-intervention year

    Effectiveness of the intervention on the community level. Health care utilization will be assessed by community-level rates of urgent care visits in children within the targeted geographic area.

Secondary outcomes

  1. Asthma-related Quality of Life (QoL) (Individual Level)

    Time frame: Asthma-related QOL will be measured at baseline, End of Treatment (EOT; 1 - 2 months after baseline, depending on intervention assignment), and every three months for 1 year.

    Effectiveness on child-level quality of life (QOL) will be measured by the Pediatric Asthma Quality of Life Questionnaire (PAQLQ). The instrument consists of 23 items related to limitation across three domains (activity limitation, symptoms and emotional function). Each item is rated 1-7 on a Likert scale, with lower numerical responses indicating greater impairment.

  2. School Absences (Community Level)

    Time frame: 12 months pre- and post-intervention year

    Community-level school absences will be assessed by attendance data (i.e., number of school absences) from the schools in the targeted area that correspond to each "step" in the wedge of the study design.
