The ophthalmic service lacks to supply spectacles following standard refraction, because of the absence of the optical dispensing unit. The aim was to determine willingness to pay for a pair of spectacles among presbyopic people if the service begins.
An interview-based questionnaire was employed among presbyopic people, who were refracted during a community-based outreach service conducted at Debre-Tabor town, South Gondar.
A total of 322 study subjects have completed the questionnaire. The median value of gross monthly income was US $75.0 (Range from US $7.1-321.4). The mean amount of willing to pay for a pair of spectacles was US $17.9 (Range from US $1.1-107.1). Participants who were willing to pay at least US $12.5 (minimum cost at the public optical dispensing unit) for a pair of spectacles accounted 63.0% (95% CI: 57.8-68.3). Based on multivariable logistics regression output analysis age ( = .049), occupation ( = .001), monthly income ( = .001), and positive history of previous spectacles wear ( = .005) show statistically significant association with willingness to pay for a pair of spectacles.
In the study area, the mean amount willing to pay for a pair of spectacles was higher than the average set of the price at the public optical dispensing units in Gondar. Public willingness to pay for a pair of spectacles could be considered as an assurance to set up an affordable and financially sustainable spectacle supply service. Conducted on a community-based outreach service may likely pool keen population segments to overestimate the result. : ANOVA: Analysis of Variance; CI: Confidence Interval; SPSS: Statistical Package for Social Science; USA: United States of America; US$: United States dollar.
由于缺乏配镜光学设备,眼科服务无法按照标准验光配镜。本研究旨在确定如果开始提供该服务,远视人群配眼镜的支付意愿。
在德布雷塔博镇进行的一项基于社区的外展服务中对远视人群进行折射后,采用基于访谈的问卷调查。
共有 322 名研究对象完成了问卷调查。毛月收入中位数为 75 美元(范围为 7.1-321.4 美元)。愿意支付一副眼镜的平均金额为 17.9 美元(范围为 1.1-107.1 美元)。至少愿意支付 12.5 美元(公立配镜光学设备的最低成本)一副眼镜的参与者占 63.0%(95%CI:57.8-68.3)。基于多变量逻辑回归输出分析,年龄(P=0.049)、职业(P=0.001)、月收入(P=0.001)和以前戴眼镜的阳性史(P=0.005)与支付配一副眼镜的意愿呈统计学显著关联。
在研究区域,支付一副眼镜的平均金额高于贡德尔公立配镜光学设备的平均价格。公众对一副眼镜的支付意愿可以被认为是建立负担得起和财务可持续的眼镜供应服务的保证。在社区外展服务中进行的调查可能会汇集有兴趣的人群,从而高估结果。
