King County Healthy Homes Project



Through the King County Healthy Homes Project, community health workers conduct home visits to low-income families with children with uncontrolled asthma. The high-intensity model includes an initial home visit by a community asthma nurse who provides patient education, training in self-management, the development of a patient-specific asthma action plan and case management/review. Families then receive in-home support, education, indoor trigger identification and resources to address environmental triggers. The low-intensity model includes an initial home visit only. During the visit, the community asthma nurse conducts an environmental assessment, develops a home action plan, provides limited education and gives families bedding encasements.
