This is a grant-funded research project from the Patient Centered Outcomes Research Institute. Its purpose is to help children and adults with asthma. The goal of the study is to work with clinics, health plans, and with patients in their homes to improve asthma care. The focus of this program is on low-income and minority asthma patients: these patients are affected on a larger scale by asthma. We are currently enrolling patients to receive up to three home visits from a Community Health Worker to help manage their asthma and clear homes of asthma triggers. Patients receive many supplies for participating. In addition to working directly with patients, we are working with 8 Neighborcare Health Community Health Centers and 5 HealthPoint Community Health Centers. We are also working with Molina Healthcare and Community Health Plan of Washington to make improvements to their Medicaid managed care plans.

Outcomes and future plans

We expect this research will improve the health of people with asthma. We hope to improve their lives by:

  • Increasing days without symptoms and by improving the quality of life for people with asthma and their caretakers.
  • Showing a new approach to asthma control. This could save money for the state Medicaid program and for other payers of health services.
  • Providing a model for improving asthma that could be shared across the state and nationally.
  • Stimulating economic activity by creating jobs for community health workers (CHW). The US Department of Labor has recently named CHWs as a distinct occupation. Hiring and using large numbers of CHWs would be a valuable economic stimulus for low income and minority communities.
  • Working with health plans and clinics to communicate better with each other, with patients, and with Community Health Workers. This saves money, increases efficiency, and makes it easier for asthma patients to access care.
  • Economic activity will also be increased by preventing missed work and school days.
