简要总结
The purpose of this study is to improve the health of African-American adults who have poorly controlled asthma. The study compares a home-based exposure reduction and asthma control intervention to enhanced in-clinic care that includes a standard clinical appointment as well as information from a detailed exposure history, asthma education, assessment for allergies, and a customized asthma self-management plan developed using motivational interviewing. The interventional group receives enhanced in-clinic care, as well as a customized home-based environmental exposure assessment and multicomponent exposure reduction and asthma control intervention (five home visits over approximately 12 months).
详细描述
The study hypothesis is that the addition of a holistic, home-based environmental exposure reduction and asthma control intervention to enhanced in-clinic care will result in statistically significant improvements in key measures of health and quality of life among Houston-area African-American adults with poorly controlled asthma.
This is a pragmatic randomized controlled clinical trial that compares the effectiveness of a customized, holistic, patient-centered, home-based environmental intervention for improving asthma control (the "intervention") with enhanced clinic-based care. Both arms receive identical in-clinic care, including collected self-report information from detailed health and exposure questionnaires, asthma education, assessment for allergies, and a customized asthma self-management plan developed using motivational interviewing. The intent of the study is to assess-real-life effectiveness of a home-based intervention in African-American adults with poorly controlled asthma.

结局指标
主要结局
Change in Juniper Mini Asthma Quality of Life Questionnaire Score (MiniAQLQ)
时间窗: At baseline (enrollment) and exit (approximately 12 mo after enrollment)
Self report. A validated 15-item questionnaire, with each question having seven possible answers score from 1 (worst) to 7 (best). Minimum total score is 15 (worst asthma quality of life). Maximum total score is 105 (best asthma quality of life). By design, an individual's score is reported as the mean (total score/15). Thus the possible mean reported score ranges from 1 (worst asthma quality of life) to 7 (best asthma quality of life).
Change in Asthma Control Test (ACT) Score
时间窗: At baseline (enrollment) and exit (approximately 12 mo after enrollment)
Self report. The ACT is a validated 5-question scale assessing asthma control over the previous four weeks. Each question has five possible responses, from 1 (worst) to 5 (best). The total score ranges from 5 (worst control) to 25 (best control). In general, a total score of 19 or less suggests poor control.
次要结局
- Change in Emergency Department (ED) Visits for Asthma(At baseline (enrollment) and exit (approximately 12 mo after enrollment))
