Incentives in Diabetic Eye Assessment by Screening (IDEAS) Trial
In Brief
A clinical study evaluating Fixed financial incentive, Probabilistic financial incentive, and 1 other intervention for Diabetes and Diabetic Retinopathy. Completed, enrolled 1,051 participants.
Detailed Summary
This trial is a randomised controlled trial to assess whether annual attendance rates at diabetic eye screening appointments in Kensington, Chelsea and Westminster could be improved by offering invitees a small financial incentive. The research questions are: 1. Are incentives an effective strategy to encourage participation in the screening programme? 2. Does the design of the financial incentive scheme affect its effectiveness in influencing participation in health screening? 3. Does the choice of incentive scheme, if successful, attract patients who have a different demographic or socioeconomic status to those who attend screening regularly? 4. Is offering these incentives a cost-effective strategy for enhancing participation?

Interventions
Participants receiving the "fixed financial incentive" intervention will be sent a screening appointment letter offering them a fixed amount of £10 if they attend their screening appointment.
Participants receiving the "probabilistic financial incentive" intervention will be sent a screening appointment letter offering them an entry into a lottery with at least a 1 in 100 chance of winning £1000 if they attend their screening appointment.
Participants receiving the "active comparator", (i.e. "control") intervention, will be sent the standard diabetic retinopathy screening appointment letter.
