Project Summary

This implementation project is complete.

PCORI implementation projects promote the use of findings from PCORI-funded studies in real-world healthcare and other settings. These projects build toward broad use of evidence to inform healthcare decisions.

This PCORI-funded implementation project expanded a community health worker asthma home visit program to new regions in Washington State.

Asthma is a health problem that can make it hard for people to breathe. More than 25 million adults and children in the United States have asthma. Removing or reducing triggers for asthma symptoms at patients’ homes, like pollen or dust, can help control symptoms.

Implementation Project Summary

What was the goal of this implementation project?

Community health workers, or CHWs, are people from the local community who are trained to teach about health and link people with health care and social services. A PCORI-funded research study showed that a CHW asthma home visit program helped people ages 5–75 with uncontrolled asthma learn about and avoid triggers for their symptoms at home. Compared with people who didn’t receive the program, people who did had more days without asthma symptoms and fewer nights when they woke up because of asthma. They also missed fewer days of work or school and had fewer emergency room, or ER, visits and improved quality of life.

This project expanded the CHW program, which was developed in Seattle and greater King County, to other communities across Washington State to make the program part of standard asthma care.

What did this project do?

The project team put the CHW program in place in four communities with diverse needs in Washington State. The team worked with three regional healthcare organizations and a federally qualified health center within these communities to:

  • Develop online tutorials for CHWs who care for patients with asthma
  • Develop in-person and virtual training sessions for CHWs, supervisors, and program managers

The project team held online and in-person meetings each month to:

  • Train CHWs to provide asthma education, help patients set goals to improve their health, and communicate with children and adults about their health concerns
  • Train CHW program managers to prepare their organizations, support and manage CHWs, and work with clinical partners

The project team trained CHWs and CHW managers. Then, the team adapted the program based on feedback from trainees.

Shortly after the launch of the CHW program in January 2020, CHWs had to stop in-person home visits due to COVID-19 social distancing guidelines. To continue the program during the pandemic, the project team adapted their materials for use during phone- and video-based home visits. The team also developed asthma education videos that CHWs could share with patients during remote or in-person home visits, or that patients could watch on YouTube.

The project team provided one-on-one support to CHWs and CHW organizations throughout the project. The team monitored progress and helped tailor the program for each community.

What was the impact of this project?

During the project, 64 CHWs and 22 CHW supervisors in counties across Washington State completed the CHW asthma home visit training program, including in rural and frontier areas.

Once trained, however, CHWs faced COVID-19-related challenges in reaching their patients with asthma. For example, CHWs had trouble signing patients up for home-based care. Also, some health departments and clinics shifted their priorities. Many CHWs had to take on new work, like contact tracing for COVID-19. As a result, the program reached fewer patients with asthma than intended during this project.

Forms completed by trained CHWs showed that:

  • 10 of the 64 trained CHWs provided asthma education visits during the project.
  • 155 people with uncontrolled asthma received an asthma visit from a trained CHW.
  • Most visits (70 percent) occurred by phone.

The training program was well accepted by participants. The project didn’t have sufficient data to assess the impact on the patients served as planned.

All trainees in the project will continue to use the program. Future sites can use the training materials for CHWs, supervisors, and program managers developed through this project to put the asthma home visit program in place. The project team has made these materials publicly available.

Project Achievements

  • Developed a comprehensive package of resources for CHWs who care for patients with asthma, including:
    • 10 interactive online training modules
    • Curricula for case-based in-person or virtual trainings
    • Curricula for CHW supervisor and program manager trainings
    • Protocols to support phone- and video-based asthma home visits
    • Patient educational videos and resources
  • Trained 86 CHWs, CHW supervisors, and CHW program managers
  • Provided CHW asthma home visits to 155 low-income patients with poorly controlled asthma

Implementation Strategies

  • Adapted the CHW asthma home visit program by modifying protocols to work with sites’ existing resources and workflows, transferring roles from research staff to site staff, and creating processes and materials to support phone- and video-based visits.
  • Provided sites with tools to support implementation, including supervisor checklists.
  • Provided educational materials to patients, as handouts and videos.
  • Trained CHWs, CHW supervisors, and CHW program managers to deliver the CHW asthma home visit program, including shadowing opportunities.
  • Used a phased implementation approach.
  • Created a learning collaborative.
  • Identified and prepared champions at sites.
  • Provided technical assistance to CHWs and CHW organizations, including practice facilitation and consultation.

Evaluation Outcomes*

To document implementation:

  • Number of Medicaid patients with severe, uncontrolled asthma receiving CHW visits
  • Fidelity to intervention protocol
  • Adaptations to program delivery
  • Implementation facilitators and barriers

To assess healthcare and health outcomes:

  • New referral pathways established with other care providers
  • Self-management goal setting and goals met
  • Symptom-free days
  • Rescue medication use
  • Missed school or work
  • Self-rated asthma control
  • Urgent care use (hospitalizations, ER visits)

*This project did not have sufficient data to complete its planned evaluation.
