糖尿病是英国和全球日益严重的公共卫生问题。糖尿病视网膜病变是糖尿病的微血管并发症，是英国工作年龄人群失明的主要原因之一。英格兰的糖尿病眼睛筛查计划旨在邀请所有12岁或以上的糖尿病患者进行视网膜照相，以筛查是否存在糖尿病视网膜病变。然而，出勤率仅为81%，使许多人面临可预防的视力丧失的风险。这是一项三臂随机对照试验，旨在研究不同类型的经济激励（基于行为经济学原理）对伦敦糖尿病眼科筛查预约就诊率增加的影响。符合条件的参与者将年满16岁或以上，并且是那些每年被邀请参加筛查预约，但在过去24个月内没有参加或打电话重新安排预约的人。控制条件（通常的邀请函）固定激励条件（通常的邀请函，包括一张10英镑的代金券，如果他们参加他们的约会）概率激励条件（邀请函，包括一张代金券，如果他们参加他们的约会，有100分之一的机会赢得1000英镑）。符合条件的参与者将被随机分配到三个条件之一：参与者将收到邀请函，主要结果将是他们是否参加约会。总共将纳入1000例受试者，按1.4：1：1的比例随机分配。为了测试激励计划是否对来自不同人口统计学或社会经济群体的患者具有不同的影响，将记录年龄、性别、与筛查中心的距离、社会经济状况和自上次筛查以来的时间长度等信息。还将进行成本效益分析。这项研究将是第一次试验的财政激励措施，以提高糖尿病眼睛筛查的吸收。如果有效的话，这种干预可能会提供一种具有成本效益的方法来提高筛查率，从而减少不必要的失明。ISRCTN14896403，2016年2月25日
Diabetes is an increasing public health problem in the UK and globally. Diabetic retinopathy is a microvascular complication of diabetes, and is one of the leading causes of blindness in the UK working age population. The diabetic eye screening programme in England aims to invite all people with diabetes aged 12 or over for retinal photography to screen for the presence of diabetic retinopathy. However, attendance rates are only 81 %, leaving many people at risk of preventable sight loss. This is a three arm randomized controlled trial to investigate the impact of different types of financial incentives (based on principles from behavioral economics) on increasing attendance at diabetic eye screening appointments in London. Eligible participants will be aged 16 or over, and are those who have been invited to screening appointments annually, but who have not attended, or telephoned to rearrange an appointment, within the last 24 months. Control condition (usual invitation letter) Fixed incentive condition (usual invitation letter, including a voucher for £10 if they attend their appointment) Probabilistic incentive condition (invitation letter, including a voucher for a 1 in 100 chance of winning £1000 if they attend their appointment). Eligible participants will be randomized to one of three conditions: Participants will be sent invitation letters, and the primary outcome will be whether or not they attend their appointment. One thousand participants will be included in total, randomized with a ratio of 1.4:1:1. In order to test whether the incentive scheme has a differential impact on patients from different demographic or socio-economic groups, information will be recorded on age, gender, distance from screening center, socio-economic status and length of time since they were last screened. A cost-effectiveness analysis will also be performed. This study will be the first trial of financial incentives for improving uptake of diabetic eye screening. If effective, the intervention may suggest a cost-effective way to increase screening rates, thus reducing unnecessary blindness. ISRCTN14896403, 25 February 2016
