In Taiwan, there were few population-based studies of WTP values related to DR screening among persons with type 2 diabetes. This community-based study was to explore the willingness- to-pay (WTP) values for screening for diabetic retinopathy (DR) associated with varying degrees of DR among persons with type 2 diabetes in Kinmen, Taiwan.
A total of 725 eligible community-dwelling adults diagnosed with type 2 diabetes received DR screening during 1999-2002 and then evaluated WTP values in 2003. Diagnosis of DR was performed by a panel of ophthalmologists using ophthalmoscopy and a 45-degree color retinal photographs to examine fundus after dilating pupils. WTP values were measured by discrete-choice method.
The 406 adults with type 2 diabetes participating in the WTP survey had a 56% response rate. Of 406 subjects, 265 (65.3%) said they would be willing to pay for DR screening to reduce blindness. The overall mean WTP value was New Taiwan Dollars 468.9 +/- 327.7 (US dollars 14.3 +/- 10.0). Age was borderline significant (p=0.07) related to WTP values. Those with severe stage DR had higher WTP values for screening than subjects with mild stage.
Degree of DR was the independent factor affecting WTP values in DR screening among community-dwelling adults with type 2 diabetes.
在台湾，基于人群的2型糖尿病患者糖尿病视网膜病变（DR）筛查意愿支付（WTP）值的研究较少。这项基于社区的研究旨在探讨台湾金门地区2型糖尿病患者对不同程度DR筛查的意愿支付值。
1999年至2002年期间，共有725名符合条件的社区成年2型糖尿病患者接受了DR筛查，并于2003年评估了他们的WTP值。DR的诊断由一组眼科医生通过检眼镜检查和散瞳后用45度彩色视网膜照片检查眼底来进行。WTP值通过离散选择法测量。
参与WTP调查的406名成年2型糖尿病患者的回复率为56%。在406名受试者中，265名（65.3%）表示愿意为DR筛查付费以预防失明。总体平均WTP值为新台币468.9 +/- 327.7（美元14.3 +/- 10.0）。年龄与WTP值的相关性接近显著（p = 0.07）。重度DR患者的筛查WTP值高于轻度患者。
DR程度是影响社区成年2型糖尿病患者DR筛查WTP值的独立因素。
