Seattle-King County Healthy Homes Project

Last updated: 2012

Model overview

Theoretical approach

SKC Healthy Homes is based on two evidence-based health behavior models-social cognitive theory and transtheoretical stages of change–and recognizes the importance of social support as a facilitating factor. The model also draws on social-ecological models of determinants of health and health behaviors.

Model services

SKC Healthy Homes included two service delivery approaches: a high-intensity and a low-intensity model. The high-intensity model included an initial home visit by a community asthma nurse who provided patient education, training in self-management, the development of a patient-specific asthma action plan, and case management and review. Families then received in-home support, education, indoor trigger identification, and resources (including bedding covers, vacuums, and cleaning supplies) to address environmental triggers. Support for self-management, medication use, and communication with health care providers also were reinforced. Community health workers (CHWs) provided these in-home services. The CHWs were educated and trained on asthma, asthma self-management, and the control of environmental asthma triggers. The low-intensity model included the initial home visit only. During the visit, the community asthma nurse conducted the environmental assessment, developed a home action plan, provided limited education, and gave families bedding encasements.
