目的本研究旨在通过探索临沂市糖尿病视网膜病变筛查(DRS)服务的支付意愿,为DRS服务的决策提供一定的研究参考。方法2022年3月到2024年2月在山东医学高等专科学校附属医院眼科进行了为期24个月的描述性横断面研究,共有425人参加本研究。收集并复核受访者的基本信息和病史。数据包括受访者姓名、年龄、性别、居住地(农村或城市)、教育程度、职业、保险、经济状况(家庭收入用于食品的比例)以及疾病史。眼科检查包括视力及眼底图像。进行糖尿病视网膜病变筛查的调查问卷。通过支付意愿的逻辑回归分析和受访者愿意支付的不同金额的线性回归分析来检查潜在因素和结果之间的关联。拟合单变量和多变量回归模型。结果在逻辑回归模型中,城市居民和为食物支付30%或以上收入的人更愿意参与DRS。在单变量线性回归模型中,男性、城市居住和受教育程度较高的人愿意支付更多费用,视力较差的受访者愿意支付较少的费用。在多变量模型中,只有男性及城市居住受访者的关联仍然显著。结论最有可能愿意支付费用的群体是城市居民和经济弱势家庭。在愿意支付一定费用的受访者中,愿意支付更多费用的人为男性和城市居民。
