To study the optimal method for delivery of spectacles at eye camps to maximize procurement and use.
A cluster randomized controlled trial, undertaken in the catchment districts of Aravind Eye Hospital - Theni, in the state of Tamil Nadu, India. Community eye camps (n = 21) were allocated to offer one of three types of service for purchase of spectacles to correct refractive error: (1) Issuance of a prescription only; (2) booking orders for spectacles with subsequent delivery; (3) on-the-spot fitting and dispensing of spectacles. Follow-up questionnaires were administered 6 weeks after interventions to assess patient outcomes. The primary outcome measured was spectacle procurement at follow-up 6 weeks post-screening. Secondary outcomes included use of and satisfaction with spectacles. Reasons for purchase/non-purchase were also assessed.
Compared to those who were issued only a prescription and adjusting for distance from base hospital, spectacle procurement was significantly higher for those allowed to book spectacles for subsequent delivery (odds ratio, OR, 8.79, 95% confidence interval, CI, 4.61-16.78) and for those receiving spectacles on the spot (OR 13.97, 95% CI 8.12-24.05). Among those with spectacles at 6 weeks, spectacle use was nearly universal and satisfaction with spectacles varied between 92 and 94% among the three different dispensing modalities.
Making spectacles available on the spot is important to ensure procurement in a context where availability and access to dispensing opticians is poor.
研究在眼科义诊活动中发放眼镜以实现采购和使用最大化的最佳方法。
在印度泰米尔纳德邦阿拉文德眼科医院（蒂鲁吉拉伯利院区）的集水区开展了一项整群随机对照试验。社区眼科义诊活动（n = 21）被分配为提供三种购买眼镜以矫正屈光不正服务类型中的一种：（1）仅开具处方；（2）预订眼镜并随后发放；（3）当场配镜和分发眼镜。干预措施实施6周后进行随访问卷调查，以评估患者的结果。测量的主要结果是筛查后6周随访时的眼镜采购情况。次要结果包括眼镜的使用情况和满意度。还评估了购买/未购买的原因。
与仅开具处方的人相比，并对距总院的距离进行调整后，允许预订眼镜以便随后发放的人（优势比，OR，8.79，95%置信区间，CI，4.61 - 16.78）和当场领取眼镜的人（OR 13.97，95% CI 8.12 - 24.05）的眼镜采购量显著更高。在6周时拥有眼镜的人中，眼镜使用率几乎达到普遍水平，三种不同配镜方式的眼镜满意度在92%至94%之间。
在配镜师的可及性较差的情况下，当场提供眼镜对于确保采购至关重要。
