新法接生率是用来评价和衡量妇幼保健工作质量的重要指标,进行新法接生率的调查是妇幼保健部门的常规工作.只有运用正确的调查方法,才能得出与实际相符的科学结论,否则,将出入很大. 以往各地报告的新法接生率有些数据很不可靠,水份较多.过去我们也做过一些抽样调查,但由于方法不一,互相之间无法进行比较.近年来国内外已采用了WHO提出的按容量比例概率抽样法(简称PPS法).根据数学理论推导,在进行调查时,一个有数十万人口的区域(如一个县),一般抽查30个调查点为宜,而每
The new law is a birth rate to assess and measure the quality of MCH work an important indicator of the birth rate of the new law is a routine survey of the work of MCH.Only by using the correct investigation methods in order to draw scientific conclusions that match with the actual, There will be a lot of discrepancies.Nevertheless, the data of the new birth rate reported in various places in the past have been very unreliable and have a lot of water. In the past, we also conducted some sample surveys, but due to the different methods, we can not compare with each other. According to the mathematical sampling theory (PPS method) proposed by WHO, according to the mathematical theory, when conducting a survey, a region of hundreds of thousands of people (such as a county), the general spot check of 30 survey points is appropriate, And every
