Overview of Presentation

• MATCH study design

• Primary outcomes

• What additional studies are needed?

• Advocacy for CHWs as evidence-based therapy

• What if CHWs were a new medication?

Preliminary Evidence Swider, 2002

• ACCESS TO CARE

• KNOWLEDGE

• BEHAVIOR CHANGE

• HEALTH STATUS… but few well-designed randomized controlled trials

that demonstrate the efficacy of CHWs

Limitations of Literature

• Absence of clear conceptual intervention model

• Failure to state hypothesis and outcomes a priori

• Weak attention to intervention fidelity

• No behavioral attention control

• Failure to blind outcome assessment

• Poor participant retention

MEXICAN-AMERICAN TRIAL OF COMMUNITY HEALTH

WORKERS

• Behavioral Randomized Controlled Trial

• Efficacy: Testing CHWs under ideal conditions

• Population:

• Community-dwelling urban Mexican-Americans

• Defined as born in Mexico themselves - or - 1 parent or 2 grandparents born in MX

• Type 2 Diabetes mellitus without major end-organ complication

[R01 DK061289]

Health Status, Behavior Change

PRIMARY STUDY OUTCOMES

Improved risk factors after 2 years

•A1c – glucose control

•% with Blood Pressure at goal (<130/80)

INTERVENTION

• Diabetes Self-management training

• Delivered by Community Health Workers

• 36 home visits over 24 months, 1-on-1 coaching

– Scheduled every 2 weeks for 1st year

– Scheduled every month in 2nd year

• Behavioral Content from American Association of Diabetes Educators (AADE-7)

MATCH CURRICULUMDiabetes Self-Management BEHAVIORS

(AADE-7) General Self-Management SKILLS

1) Check blood glucose daily and understand the results

1) Problem-solve using brainstorming (“lluvia de ideas”)

2) Take action to respond to abnormally high or low blood glucose results

2) Record adherence to specific diabetes behaviors through the use of a journal or written log (“márquelo”)

3) Obtain regular medical care and communicate your concerns with your medical providers

3) Restructure the environment to either support desired behaviors or reduce the risk of unhealthy behaviors (“cambielo”)

4) Take medications as prescribed by your medical provider

4) Seek out social support from family members or friends

5) Check your feet regularly 5) Use strategies to reduce stress

6) Engage in daily physical activity

7) Make healthy dietary choices, with emphasis on reducing the fat content of meals

INTERVENTION FIDELITY

• CHWs documented content of visits, duration, skills taught

• All encounters audiotaped with random audits and feedback by physician, psychologist

• Average visit time ~ 90 minutes

• High rates of adherence / completion

CONTROL CONDITION

• Diabetes Self-management curriculum

• Delivered by bilingual newsletters mailed to home

• 36 newsletters, 24 months

• Same AADE 7 Content and self-management skills as in CHW intervention arm

OUTCOME ASSESSMENT

• Research Assistants blinded to group allocation; separated from CHW interventionists

• NO use of information from CHWs used to follow-up participants (differential ascertainment)

• High retention rates at 2 years: 121 out of 144 randomized (84% retention)

• Intention to treat analysis

NEXT STEPS?

• Other racial / ethnic groups

• Increased emphasis on BP control

• Increased emphasis to other risk factors

• Evaluate sustainability post-intervention

• Determine optimal maintenance dose

• Multi-center Effectiveness Trial – test under “real world conditions”

• Patient-oriented outcomes (Hospitalization, Complications, Death)

AN ACTION AGENDA FOR CHWs

• Document the costs and benefits of existing CHW interventions

• Educate payer & business community

• Educate health care sector

• Advocate for policies that support CHWs– Training

– Career ladder

Conclusion

We have an effective, safe intervention that brings best clinical practices and improved diabetes control to people who experience excess disability and death due diabetes health disparities

Is there a reason to wait to disseminate this intervention while we gather more data and refine the intervention further?

What if CHWs were a Medication?
