背景：在台湾，关于2型糖尿病患者中与DR筛查相关的WTP值的人群研究很少。这项以社区为基础的研究旨在探讨台湾金门地区2型糖尿病患者中与不同程度DR相关的糖尿病视网膜病变(DR)筛查的支付意愿(WTP)值。方法：1999-2002年，共有725名符合条件的社区2型糖尿病成人接受DR筛查，并于2003年评估WTP值。DR的诊断是由一个眼科医生小组进行的，他们使用眼底镜和45度彩色视网膜照片来检查散瞳后的眼底。结果：参加WTP调查的406名成人2型糖尿病患者的有效率为56%。在406名受试者中，265名(65.3%)表示他们愿意为DR筛查付费以减少失明。整体平均WTP值为新台币468.9+/-327.7(美元+/-10.0)。年龄与WTP值呈极显著正相关(p=0.07)。结论：糖尿病视网膜病变程度是影响社区成年2型糖尿病患者糖尿病视网膜病变筛查WTP值的独立因素。
BACKGROUND: 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.METHODS: 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.RESULTS: 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.CONCLUSIONS: Degree of DR was the independent factor affecting WTP values in DR screening among community-dwelling adults with type 2 diabetes.
