我们介绍了一种创新的方法，在家庭调查中使用配备全球定位系统(GPS)单元的个人数字助理(PDA)来选择基于概率的样本并进行基于PDA的访谈。我们的方法使用带有GPS的掌上电脑快速绘制选定地区的所有家庭地图，随机选择样本，然后导航回样本家庭进行访谈。作为非洲疟疾控制努力的一部分，我们介绍了两个具有全国代表性的大规模家庭调查的最新实地经验，以评估杀虫剂处理的蚊帐覆盖率。这一方法的成功应用产生了统计上有效的样本；质量受控的数据输入；以及在完成实地工作后的几天内快速汇总、分析和提供初步结果。当在枚举区水平几乎没有人口普查信息的环境中需要快速、统计有效的调查时，我们建议将该方法作为扩大免疫规划整群抽样方法的替代方法。
We introduce an innovative method that uses personal digital assistants (PDAs) equipped with global positioning system (GPS) units in household surveys to select a probability-based sample arid perform PDA-based interviews. Our approach uses PDAs with GPS to rapidly map all households in selected areas, choose a random sample, and navigate back to the sampled households to conduct an interview. We present recent field experience in two large-scale nationally representative household surveys to assess insecticide-treated bed net coverage as part of malaria control efforts in Africa. The successful application of this method resulted in statistically valid samples; quality-controlled data entry; and rapid aggregation, analyses, and availability of preliminary results within days of completing the field work. We propose this method as an alternative to the Expanded Program on Immunization cluster sample method when a fast, statistically valid survey is required in an environment with little census information at the enumeration area level.
