Brief Summary:

The specific aims of this study are to test whether in a cohort of low-income minority veterans with poor diabetes mellitus (DM) control:

  1. Peer counseling is an effective means of reducing HbA1c (a measure of glucose control).
  2. Financial incentives are an effective means of reducing HbA1c. This is a randomized controlled pilot study. There will be 3 arms: 1) a control group of poorly controlled diabetics getting usual care; 2) peer counseling with no incentives; and 3) financial incentives without peers. Ultimately, contingent on the success of this intervention, the researchers plan to apply for funding for a large scale intervention employing both peer counseling and incentives to improve DM control in low income and minority patients who are at high risk for premature morbidity and mortality.

Arm Intervention/treatment
No Intervention: Control
This group will receive usual diabetes care through their primary care clinicians.
Experimental: Peer counseling
A peer counselor will be assigned to each participant who currently has good diabetes control but had poor control in the past 3 years.
Behavioral: Assigned a peer counselor
Dyads will be given $20 per month if they have contact 4 or more times during a month.

Experimental: Financial incentives
Patient participants in the financial incentive arm will be given $100 for reduction of HbA1c by 1 point in a 6 month period and $200 for reduction by 2 points.
Behavioral: Financial incentives
Participants will be given $100 for reduction of HbA1c by 1 point in a 6 month period and $200 for reduction by 2 points.

Primary Outcome Measures :
  1. Hemoglobin A1c [ Time Frame: Baseline, 6 months ]
    Change in HbA1c from baseline will be the primary outcome measure.

Secondary Outcome Measures :
  1. Counts of the number of hypoglycemic events [ Time Frame: 6 months ]
    All events and serious events related to hypoglycemia will be counted over the 6 month intervention period, including emergency room visits and hospitalizations.

  2. Number of peer encounters [ Time Frame: 6 months ]
    The number of peer encounters by arm will be described.

  3. Experience of peer counseling [ Time Frame: 6 months ]
    The experience of peer counseling from both poorly controlled diabetics and counselors will be described.
