Slide 2

Community Health Workers (CHW) to improve functioning in diabetes + chronic pain

• Pain is common in diabetes:
  • 60-80% persons with diabetes report chronic pain.
  • Osteoarthritis (OA) most common cause.
• Pain is a barrier to self-care.
• Cluster-randomized controlled trial (RCT), rural Alabama:
  • Participants: adults w. diabetes + chronic pain.
  • Intervention:
    • CHW-delivered telephone + DVD.
    • Cognitive behavior training to maximize functioning despite pain.
    • Diabetes self-care.
    • Comparative Effectiveness Reviews (CERs): OA, diabetes; integrated into education/training program content.
  • Outcomes: risk factors (A1c, BP, chol), functional status.

Slide 3

Reach

• Participation rates.
• Representativeness among the sampling frame of patients with diabetes.

Strengths:

• Telephonic delivery.

Challenges:

• Community realities—"bring a neighbor".
• Denominators.

Slide 4

Reach

• HIGH.

Slide 5

Efficacy/Effectiveness:

• Design: RCT.
• Outcomes:
  • Primary:
    Metabolic control (A1c, BP, chol).
    Functional status.
  • Secondary:
    Self-care behaviors.
    Cost.

Strengths:

• Community setting—representativeness/effectiveness.
• One-on-one, potent intervention.
• DVD component.

Challenges:

• Community-member delivered—intervention fidelity.

Slide 6

Effectiveness

• MED-HIGH.

Slide 7

Adoption:

• More speculative (!).
• Cost.
• Requires new resources?

Strengths:

• Low-cost.

Challenges:

• No infrastructure to sustain program (Healthcare Reform?).

Slide 8

Adoption

• LOW (MED?).

Slide 9

Implementation:

• Low complexity: high.
• Sustainable intervention fidelity: high.

Strengths:

• Cultural concordance lowers complexity.
• Telephone.

Challenges:

• Community interventionists increase complexity.
• Training needs.
• Reliance on tenuous infrastructure (Healthcare Reform?).

Slide 10

Implementation

• LOW (MED?).

Slide 11

Maintenance:

• Individual:
  • What is f/u?
  • Do social networks form?
  • Is tailoring required?
• System:
  • Does motivation for intervention reside in community-based organization?
  • Outreach via telephone: low cost, flexible (reimbursement?).

Slide 12

Maintenance:

• Strengths:
  • Social networks?
  • Telephone delivery.
• Challenges:
  • No structure for sustained f/u (Healthcare Reform?).
  • Motivation for intervention does not reside in community-based organization.

Slide 13

Maintenance

• MED.
