了解疾病的空间分布对于有效的疾病控制至关重要。在不存在正式地址网络的地方，很难跟踪临床疾病的空间模式。地理定位战略在肯尼亚西部的农村卫生设施进行了测试。方法包括大院负责人对住所进行地理编码，参与性绘图和记录自我报告的最近地标。地理编码能够将72.9%[95%置信区间（CI）67.7 - 77.6]的个体定位到距离真实化合物位置250 m以内。参与式绘图作业能够将82.0%的化合物（95%CI 78.9 - 84.8）正确定位到具有500 m缓冲区的2 × 2.5 km区域。自我报告的最近地标能够将78.1%（95%CI 73.8 - 82.1）的化合物定位到正确的集水区。这些策略测试提供了快速获得个人在卫生设施的空间信息的选项。
Understanding the spatial distribution of disease is critical for effective disease control. Where formal address networks do not exist, tracking spatial patterns of clinical disease is difficult. Geolocation strategies were tested at rural health facilities in western Kenya. Methods included geocoding residence by head of compound, participatory mapping and recording the self-reported nearest landmark. Geocoding was able to locate 72·9% [95% confidence interval (CI) 67·7–77·6] of individuals to within 250 m of the true compound location. The participatory mapping exercise was able to correctly locate 82·0% of compounds (95% CI 78·9–84·8) to a 2 × 2·5 km area with a 500 m buffer. The self-reported nearest landmark was able to locate 78·1% (95% CI 73·8–82·1) of compounds to the correct catchment area. These strategies tested provide options for quickly obtaining spatial information on individuals presenting at health facilities.
