Brief Summary
This study tests the hypothesis that community health workers providing home visits to provide education and support for self-management of asthma, assessment of the home for environmental triggers, resources for asthma control, and assistance in effective communication with medical providers over the course of one year would reduce asthma morbidity, asthma-related urgent health care use and exposure to indoor asthma triggers among low income adults with not well controlled asthma.

Study Arms (2)
Community Health Worker support
EXPERIMENTALhome visits from community health workers providing education and support for self-management of asthma, assessment of the home for environmental triggers, resources for asthma control, and assistance in effective communication with medical providers
the usual care control group
NO INTERVENTIONUsual care is defined as services received by participants in the absence of the intervention plus information about community resources that support asthma self-management (such as classes and support groups) and educational pamphlets
Interventions
For the intervention group, a trained Community Health Worker (CHW) provided education, support and service coordination through home visits. The CHW first made an in home assessment visit. At the assessment visit, the participant had the opportunity to ask questions and sign written consent. During this visit, the CHW assessed the participant's knowledge of asthma, current status of asthma control, challenges with controlling asthma, self-management practices and exposure to asthma triggers. After enrollment, the participant received up to four follow-up educational visits 0.5, 1.5, 3.5 and 7 months later. In addition to scheduled visits, the CHWs worked with their participants on an as-needed basis via telephone, email, or additional home visits.
