G2P: Guidelines to Practice: Reducing Asthma Health Disparities Through Guideline Implementation
Study Details
Study Description
Brief Summary
The primary hypothesis the investigators will test is that that improving asthma guideline implementation and providing patients with a unified asthma management plan using a multi-component and multilevel intervention will improve patient-centered asthma outcomes compared to health plan case management, passive guideline dissemination and provider education.

Detailed Description
The study will use a factorial randomized controlled design to assess the comparative effectiveness of the following interventions among 8 community health centers and 550 patients with:
-
Health plan enhanced intervention plus traditional provider education: Health plans will enhance case management support, monitor medication fills, and increase passive guideline dissemination. Traditional provider education will consist of implementation of the PACE asthma education program. Note that all participants and clinics will receive this intervention. In effect, this will be the base active comparator arm of the study.
-
Home visit intervention: Community health workers will provide in-home tailored asthma support: assess asthma self-management knowledge and skills, conduct a home environmental assessment focused on asthma triggers, and conduct follow-up visits to support patient actions to improve asthma control based on unified asthma management plan.
-
Enhanced clinic intervention with system integration: Clinics will implement a multi-component intervention that includes decision support, audit and feedback, provider and staff education, team-based care, and training and feedback in implementing office spirometry and allergy testing. EHR enhancements and clinic systems redesign will support this work. The EHR will also provide a platform for sharing a common asthma management plan and enhancing communications among care team members (clinicians, CHWs, plan case managers).
All four intervention groups will receive enhanced health plan intervention + provider education. The four study arms will receive the following additional different interventions: (a) usual clinic care; (b) a + home visit, (c) enhanced clinic care + system integration, and (d) c + home visit.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Enhanced Clinic+ Unified Management Plan Patients in study arm will receive: Enhanced Clinic Intervention Enhanced Health Plan Unified Management Plan |
Behavioral: Enhanced Clinic+ Unified Management Plan
Unified asthma management plan and asthma support team coordination: A support team (clinicians, CHWs and plan care managers) will partner with each patient to develop a single asthma management plan. An EMR will provide a web-based platform for sharing the unified asthma management plan and enhancing communications among care team.
Enhanced clinic intervention: Intervention clinics will implement a multicomponent intervention that will include decision support, audit and feedback, provider and staff education, asthma champions, team-based care, and spirometry, all supported by EMR enhancements and clinic systems redesign.

Behavioral: CHW Home Visit Only
-Home visit intervention: Community health workers will provide in-home tailored asthma support: assess asthma self-management knowledge and skills, conduct a home environmental assessment focused on asthma triggers, and conduct follow-up visits to support patient actions to improve asthma control based on unified asthma management plan.
