From: Financial incentives to improve glycemic control in African American adults with type 2 diabetes: a pilot randomized controlled trial

Group Description Incentive Structure
Group 1: Low Frequency Financial Incentive Single incentive at 3-months for absolute percentage drop in HbA1c from baseline to 3-month follow-up, up to $300. HbA1c Reduction: After 3 months, if their HbA1c has dropped 2% from baseline, or absolute HbA1c is 7%, they will receive a reward of $300. For a 1% drop, or an absolute HbA1c between 7 and 8 they will receive a reward of $150
Group 2: Moderate Frequency Financial Incentive Single two-part incentive for uploading glucose measurements through home testing of glucose and absolute percentage drop in HbA1c from baseline to 3-month follow-up, up to $300. Glucose Uploads: Each week participants in Group 2 can receive up to $10 for uploading glucose measurements and having good glucose control throughout the week. For each day they upload at least one glucose measurement, they will receive $1 (up to $7 at the end of the week). If they upload measurements every day of the week and their average glucose measurements at the end of the week are 150 or below, they will receive an additional $3 for up to $10 per week for 3-months.
HbA1c Reduction: After 3 months, if their HbA1c has dropped 2% from baseline, or absolute HbA1c is 7%, they will receive a reward of $170. For a 1% drop, or an absolute HbA1c between 7 and 8 they will receive a reward of $85.
Group 3: High Frequency Financial Incentive Single multiple component incentive for uploading glucose measurements using home testing, attending weekly phone educational sessions, and absolute percentage drop in HbA1c from baseline to 3-month follow-up, up to $300. Glucose Uploads: Each week participants in Group 3 can receive up to $10 for uploading glucose measurements and having good glucose control throughout the week. For each day they upload at least one glucose measurement, they will receive $1 (up to $7 at the end of the week). If they upload measurements every day of the week and their average glucose measurements at the end of the week are 150 or below, they will receive an additional $3 for up to $10 per week for 3-months.
Attendance of Educational Sessions: Educational sessions will last for 8 weeks, so they can receive up to $5 per week for 8 weeks.
HbA1c Reduction: After 3 months, if their HbA1c has dropped 2% from baseline, or absolute HbA1c is 7%, they will receive a reward of $130, for a 1% drop, or an absolute HbA1c between 7 and 8 they will receive a reward of $65.
