Detaljeret beskrivelse
We used a randomized controlled parallel group design to compare the intervention to a usual-care control group. We attempted to evaluate the effectiveness of the intervention in the "real world," rather than its ideal efficacy.
The CHWs used protocols that specified education content, participant skill development and participant and CHW actions. The CHWs modified their approach to meet the priorities of participants using motivational interviewing techniques. They addressed asthma patho-physiology, reliever and controller medication use, self-monitoring, use of an asthma action plan, environmental assessment, trigger avoidance, effective use of the health care system, successful communication with health care providers, and weight control (obesity is associated with increased asthma symptoms). Participants also received low-literacy educational materials, in English or Spanish. The education concepts and environmental assessment activities were based on our prior healthy homes work modified for adults.

Eksperimentel: Community Health Worker support
home 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
|
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.
