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.

The description of the implementation of the model(s) here may differ from how the model(s) was implemented in the research reviewed to determine this model’s evidence of effectiveness. Inclusion in the implementation report does not mean the practices described meet the HHS criteria for evidence of effectiveness. Similarly, models described here may not all have impact studies, and those with impact studies may vary in their effectiveness.

The Seattle-King County (SKC) Healthy Homes project was implemented by Public Health - Seattle & King County, located in Washington State. The project was sponsored by the King County Asthma Forum and funded through the National Institutes of Environmental Health Sciences.
SKC Healthy Homes was offered to low-income households of children with persistent asthma residing in Seattle and King County. Participants were patients at community health centers. A screening tool was available to help identify eligible families.
The project aimed to reduce asthma morbidity and related health care utilization and improve asthma-related quality of life by increasing asthma self-management skills and reducing exposure to indoor asthma triggers among low-income children with uncontrolled asthma.
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.
Model intensity and length
The high-intensity model of SKC Healthy Homes included an initial intervention visit from a community asthma nurse and up to six followup visits conducted by a CHW during a one year period. The low-intensity model included the initial intervention visit only.
