Eye conditions in children can have negative consequences on visual functioning and quality of life. There is a lack of data on the magnitude of children with eye conditions who need services for effective planning of school eye health programmes. To address this, the School Eye Health Rapid Assessment (SEHRA) tool is being developed to collect data to support school eye health programme planning.
The module, 'the magnitude and nature of local needs in school children' is the first of six modules in the SEHRA tool. The module outlines a school-based cluster survey designed to determine the magnitude of eye health needs in children. This paper outlines the survey sampling strategy, and sample size calculations.
The requirements for the SEHRA survey indicate that in regions where a larger sample size is required, or where fewer schools are recruited to the survey, confidence in the accuracy of the data will be lower.
The SEHRA survey module 'the magnitude and nature of local needs in school children' can be applied in any context. In certain circumstances, the confidence in the survey data will be reduced.
儿童眼部状况可能对其视觉功能和生活质量产生负面影响。由于缺乏儿童眼部状况严重程度的数据，因此难以有效规划学校眼保健计划。为了解决这个问题，正在开发学校眼健康快速评估（SEHRA）工具来收集数据，以支持学校眼保健计划规划。
模块“儿童在校的局部需求的规模和性质”是 SEHRA 工具的六个模块中的第一个。该模块概述了一项基于学校的聚类调查设计，旨在确定儿童眼健康需求的规模。本文概述了调查抽样策略和样本量计算。
SEHRA 调查的要求表明，在需要更大样本量或向调查招募较少学校的地区，对数据准确性的信心将降低。
SEHRA 调查模块“儿童在校的局部需求的规模和性质”可应用于任何环境。在某些情况下，调查数据的置信度将会降低。
