West Philadelphia Controls Asthma (WPCA)

West Philadelphia Asthma Care Implementation Plan

This project uses community health workers (CHW) or lay health educators to implement asthma interventions that have been proven to work in the primary care setting and in schools. The objective is to integrate the home, school, healthcare system, and community for 640 school-aged asthmatic children in West Philadelphia through use of CHWs.

The children enrolled in the study will be randomized to one of four groups including: primary care CHW, school CHW, primary care and school CHW or the control group (no CHW).

Study Overview

• Status: Completed
• Conditions: Childhood Asthma; Community Health Workers
• Intervention / Treatment: Behavioral: Yes We Can Children's Asthma Program; Behavioral: Open Airways for School Plus; Behavioral: School-Based Asthma Therapy

Detailed Description

The Community Asthma Prevention Program (CAPP) at the Children's Hospital of Philadelphia has a two-decade history of utilizing CHWs to improve asthma outcomes of children in Philadelphia. Building on this foundation, a network of stakeholders was established including, The West Philadelphia Asthma Care Collaborative (WEPACC), with representation from public housing, healthcare, community, and schools. As a result of assessment of local needs, resource mapping, and months of planning, Investigators designed an asthma care implementation program with the broad objective of integrating home, school, healthcare system, and community for school-aged asthmatic children in West Philadelphia. Investigators seek to accomplish this goal using CHWs to deliver sustainable patient-centered evidence-based interventions. The evidence-based interventions include (1) a primary care-based Yes We Can intervention with home visitation and (2) a comprehensive and rigorously evaluated school-based intervention, Open Airways for schools and School Based Asthma Therapy. CHWs will function as the hub of each interventions, serving either as primary care CHWs or school CHWs to provide a network of education, care coordination support, and to facilitate communication for families of children with asthma between the four sectors. This project seeks to integrate interventions in a comprehensive and sustainable manner to reduce asthma disparities in poor, minority children.

Using a factorial design, Investigators will recruit and randomize 640 asthmatic children (ages 5-13 years) from up to five inner-city primary care clinics who attend one of 36 West Philadelphia schools to one of four study conditions: both interventions (both primary care and school CHWs intervention), primary care CHW or school-CHW alone, or control and follow for one year. As a part of this project the Investigators seek to accomplish the following objectives:

Objective 1. Compare effectiveness of the primary care and school interventions to improve asthma control and reduce symptom days using main and simple effects from the factorial design.

Objective 2. Explore moderators and mechanisms of effectiveness and sustainability of the interventions.

Objective 3. Use mixed methods to explore implementation determinants and outcomes of school intervention that promote effectiveness, fidelity and sustainability

Objective 4. Examine the costs, savings, and cost effectiveness associated with the intervention and implementation strategies to promote sustainability.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Asthma Control	Asthma Control Questionnaire (ACQ) developed by E.F. Juniper et al. is a 6-item recall of asthma control indicators over the past week and one objective measure of airway caliber (FEV1%) through pulmonary function testing. The 6-item recall includes awakening at night with asthma symptoms, asthma symptoms upon waking, activity limitations due to asthma symptoms, shortness of breath, wheezing, and administration of asthma rescue medications. The score range for the ACQ is 0 - 6, with lower numbers indicating poor asthma control and higher numbers indicating greater asthma control.	Baseline and 3, 6, 9, and 12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Asthma Symptoms	Asthma symptoms will be measured using a 2-week recall diary	Baseline and 3, 6, 9, and 12 months
Change in School Absences	School and parental report of child's school absences pre and post study enrollment	Baseline and 12 months
Change in Emergency Department (ED) visits and hospitalizations	ED visits and hospitalizations for an asthma-related cause in the 12 months pre and post study enrollment	Baseline and 3, 6, 9, and 12 months
Intervention Cost-Effectiveness	Healthcare costs for child during the 12-month follow-up period will be measured by parental report using a 3-month recall diary	Baseline and 3, 6, 9, and 12 months
Change in Asthma Caregiver's Quality of Life	The Paediatric Asthma Caregiver's Quality of Life Questionnaire (PACQLQ) by Juniper et al. is a 13-item measure of asthma caregiver's quality of life in two domains, activity limitation and emotional function, over the past week. All items are weighted equally and the score range is 1 - 7, with lower numbers indicating poor quality of life and higher numbers indicating better quality of life around caring for a child with asthma.	Baseline and 12 months
Baseline School Asthma Program Sustainability	Semi-structured interviews with key school staff members and parents at the start of the intervention to assess barriers to sustainability of the intervention	At start of school intervention
Post-Intervention School Asthma Program Sustainability	Semi-structured interviews with key school staff members and parents one year after the school intervention has ended to assess barriers to sustainability of the intervention	One year post end of school intervention
Baseline School Climate	The Organizational Climate Index (OCI) is a 30-item descriptive measure for schools. The index has four dimensions: principal leadership, teacher professionalism, achievement press for students to perform academically, and vulnerability to the community. The score range for each questionnaire item is 1 - 4. The range for the principal leadership and teacher professionalism dimensions is 7 - 28. The range for achievement press is 8 - 32. The range for vulnerability to the community is 5 - 20. Higher scores reflect a better organizational climate. The total school score, range 27 - 108, is computed by summing the subscale means. Total school score can be converted to standardized scores and compared with national norms.	At start of school intervention

Total school score can be converted to standardized scores and compared with national norms.	One year post end of school intervention
Baseline School Leadership	The Implementation Leadership Scale (ILS) is comprised of 12 items assessing the degree to which a leader is Proactive, Knowledgeable, Supportive, and shows Perseverance in implementing evidence-based practice. The range for total score and each subscale score is 0 - 4. Higher scores represent better implementation leadership. The mean of the subscale scores yields the total score.	At start of school intervention
Post-Intervention School Leadership	The Implementation Leadership Scale (ILS) is comprised of 12 items assessing the degree to which a leader is Proactive, Knowledgeable, Supportive, and Perseverant in implementing evidence-based practice. The range for total score and each subscale score is 0 - 4. Higher scores represent better implementation leadership. The mean of the subscale scores yields the total score.	One year post end of school intervention
Baseline School Staff Attitudes	The Evidence-Based Practice Attitude Scale (EBPAS) is a 15-item self-report measure of attitudes toward adoption of EBPs. It consists of four subscales: Appeal (is EBP intuitively appealing), Requirements (would an EBP be used if required), Openness (general openness to innovation), and Divergence (perceived divergence between EBP and current practice). Total score range is 0 - 60. The Appeal, Openness, and Divergence subscales have a range of 0 - 16. The Requirements subscale has a range of 0 - 12. Higher scores indicate more positive attitudes. Subscales are summed to compute a total score.	At start of school intervention
