群随机设计的农村地区产前保健项目评价

Evaluation of a cluster randomized designed prenatal care object in rural areas

目的:评价产前保健是否能改善围产儿健康水平。方法:运用群随机设计方法,选取定远县55个乡镇中具备实施干预基础条件的20个乡镇,按照社会经济发展、孕产期保健服务的提供和利用等指标进行匹配,随机将乡镇分入干预组和对照组。干预内容包括:①对乡镇医疗机构的产科医生进行培训,使其能够提供系统的产前保健服务;②通过发放宣传单,张贴海报等形式,告知产前保健的重要性;③为乡镇医院提供基本的产前检查设备。通过应用观察、小组讨论、问卷调查等方法对所获得的资料进行评价。结果:过程评价发现,干预措施未能完全按照计划实施。主要的制约因素有:卫生部门与计划生育部门的工作协调有障碍;项目实施期间有关政策发生改变;政府对母婴保健工作的投入不足。结果评价显示干预组和对照组的围产儿死亡率差别无统计学意义。结论:由于项目受到政策改变等因素的影响而未能完全按计划实施,因此,该研究未能回答产前保健是否能改善妊娠结局这一问题;在开展社区卫生项目评价中,为真正了解项目是否能够取得预期效果,过程评价和结果评价都是必需的。
