Incentives in Diabetic Eye Assessment by Screening (IDEAS) Trial

Imperial College London·interventional·Posted Jan 16, 2015·Updated Oct 19, 2023

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?
