Since 1989 an evaluation study of the impact of a Primary Health Care (PHC) program is being carried out in Arsi region, Ethiopia. The principal aim of the study is to estimate the mortality rates in those villages mainly involved in PHC activities. A sample of 80 villages will be recruited to allow significant differences in mortality of 20 per thousand between less treated and best treated villages. Considering the absence of routine demographic data, a population census and demographic surveillance of the recruited villages have been carried out. All the activities related to the study are considered together with the principal logistic and methodologic problems.
自1989年以来，埃塞俄比亚阿尔西地区一直在开展一项关于初级卫生保健（PHC）项目影响的评估研究。该研究的主要目的是估计那些主要参与初级卫生保健活动的村庄的死亡率。将选取80个村庄作为样本，以便使治疗较少的村庄和治疗最佳的村庄之间的死亡率存在千分之二十的显著差异。鉴于缺乏常规人口数据，已对所招募村庄进行了人口普查和人口监测。与该研究相关的所有活动以及主要的后勤和方法学问题都进行了综合考虑。
