摘　　要：目的了解患者对肠道准备药物的支付意愿水平并估算支付意愿(WTP)阈值,为促进合理用药提供参考。方法以二分式条件价值评估法设计调查问卷;对数据进行描述性统计,计算累计频度中位值作为平均WTP,并基于年龄段、就诊医疗机构级别等特征变量进行亚组分析。结果患者平均WTP为264.55元/1%。亚组中30~40岁、东北地区、就诊三级医疗机构,个人年收入>35万元和家庭年收入>60万元的患者所在组别的平均WTP较大。结论本次调查估算的WTP值可为肠道准备药物的成本-效果分析提供阈值参考。二分式条件价值评估法能有效引导患者给出真实的支付意愿。一般而言,患者就诊医疗机构级别、收入水平越高,其WTP越高,实际应用时可结合人群特征适当调整该阈值。Objective To determine patients’willingness to pay(WTP)for bowel preparation medications and the WTP threshold,to promote rational medication use.Methods The WTP questionnaire was designed by dichotomous contingent evaluation method.The statistical data were described.The median cumulative frequency value was calculated as the mean WTP,and subgroup analysis was performed based on the characteristic variables of age groups and level of medical institutions.Results The mean WTP of the patients was 264.55 yuan/1%.The groups with the largest mean WTP in each subgroup were 30~40 year olds,from Northeast China,visiting a tertiary care institution,having an annual personal income of>350000 yuan,and an annual household income of>600000 yuan.Conclusion The WTP estimated in this survey may provide a threshold reference for the cost-effectiveness analysis of bowel preparation drugs.The dichotomous contingent evaluation method effectively guides patients to show their true willingnessto-pay.In general,the higher the level of the medical institutions the patients’visit and their income level,the higher their WTP.The threshold value can be adjusted with the characteristics of the population when using the threshold in practice.
