Cambodia (2004): MAP Study Evaluating the Coverage and Quality of Coverage of Malaria Prevention, Diagnostic, and Treatment Products. First Round.

In June 2004, Population Services International in Cambodia (PSI/Cambodia) conducted a Project MAP survey to identify the baseline coverage of Malaria diagnosis, prevention, and treatment products. Coverage indicates geographic access by users from retail outlets. The fundamental goal of this process was to assist in refining and expanding an existing social marketing program by clarifying the status of product placements and exposing strengths and weaknesses in the market. The survey investigated all available malaria treatments, including Malarine for Children (called Malarine-3 at the time of fieldwork) and Malarine for Adults (called Malarine-4 at the time of fieldwork), Rapid Diagnosis Tests (RDTs; including Paracheck/Malacheck), untreated bednets, insecticide treated bednets, and insecticide treatment kits. Lot Quality Assurance Sampling (LQAS) was used for data analysis. LQAS is a statistical method that combines a sampling framework and one-sided hypothesis testing for data analysis that allows for the sample selected from each lot to be quite small, while still providing valid and useful results.

2004年6月，国际人口服务组织柬埔寨分部（PSI/柬埔寨）开展了MAP项目调查，旨在明确疟疾诊断、预防与治疗产品的基线覆盖率。此处的覆盖率指用户通过零售网点获取产品的地理可及性。本次调查的核心目标为，通过厘清产品布局现状、剖析市场的优势与不足，助力优化并拓展现有社会营销项目。本次调研涵盖所有可获取的疟疾治疗相关产品，包括儿童用疟疾宁（现场调研阶段命名为Malarine-3）与成人用疟疾宁（现场调研阶段命名为Malarine-4）、快速诊断检测试剂（Rapid Diagnosis Tests, RDTs；含Paracheck/Malacheck）、未处理蚊帐、经杀虫剂处理的蚊帐以及杀虫剂处理套装。数据分析采用批量质量保证抽样（Lot Quality Assurance Sampling, LQAS）方法。LQAS是一种结合抽样框架与单侧假设检验的统计分析手段，允许从每个批量中抽取规模极小的样本，同时仍可获得有效且具备实用价值的分析结果。
