为确保1991年儿童死亡基础调查质量,首都儿科研究所采取核查基础资料、召开座谈会、信件反馈及走访调查等方法,再次对生命监测地区的基础调查数据进行了质量控制。结果表明,监测地区仍存在不同程度的漏报现象,而且农村的漏报率明显高于城市,沿海地区儿童出生和死亡漏报情况明显低于内地和边远地区。
In order to ensure the quality of the basic investigation of child deaths in 1991, the Capital Institute of Pediatrics took the verification of basic information, held symposiums, letters and visits, and conducted surveys and other methods to further control the quality of the basic survey data in the life monitoring areas. The results show that there are still some underreporting phenomena in monitoring areas, and the false negative rate in rural areas is obviously higher than that in urban areas. The incidence of omission in birth and death of children in coastal areas is obviously lower than that in the interior and remote areas.
