The Feasibility Analysis Of The Proposal Of The Third National Mortality Retrospective Sampling Survey

According to the current situation that our country haven't yet built up a consummate system on vital statistics system, it is hard to handle the real,dynamic,precise situation of people's mortality and it's changing trend.To aim directly at these questions and made the third National Mortality Retrospective Sampling Survey feasible, Ministry of Health organized a small scale preliminary test in some areas in december of 2005. The main objective of the preliminary test is to check the maneuverability of the survey method,to evaluate the feasibility of the techniqual route for the formal survey,to find out the key point of the factors which have a contribution to the survey quality and to provide scientific foundation for the proposal formal survey.Objective:Utilizing the data of the preliminary test of the third National Mortality Retrospective Sampling Survey to point out the problems of the proposal,to analysis the feasibility of the survey proposal and to provide constructive view for the formal survey.Method:Verificating the population data,death data and other correlation information from the areas of where already carried out the registration of death causes, compare different resource data between different departments and use rate of missing report and coincidence to evaluate the dependablity and accuration of the data collected in the survey.Making use of SPSS 10.0 statistical analysis software and chi square test to analysis the variability of rate between different resource data and the variability between city and rural areas on the aspect of data collecting.Result:1.Either city area or rural area collecting population data department is Public Security Bureau.Get birth pupolation data from birth-control committee.If no birth information is found in rural areas,we can use crude rate of missing report of birth population to estimate prediction consequence.2.On the aspect of collecting death data,either city area or rural area, the departments of the death causes registration exists the phenomenon of loss.The rate of missing report of city area and rural area is different from each other and have significance disparity through chi square test(P<0.05).3.The survey results displayed that dysoemia and basic death cause unknowed cases occupied mostly of all the death cases.Adding death cause inference measuring scale in order to accord with quality control index.4.Quality control is essential and important during the whole survey because on the aspect of collecting data and definiting the death cause,it is esay to have quality problems.Conclusion:The result of the mortality survey in city areas and rural areas of where already carried out the registration of death causes shows that the method of the mortality survey is feasible,and it can be reflected as the reasons below:1. either city area or rural area the Public Security Bureau is the department that controls almost the whole population data,and from where we can collect the population data;2.the birth-control committee and Maternal and Child Health department control almost the whole birth pupolation data and infant death data,they are the one from where we collect the data about birth population and infant death;3.the department of death cause registration controls the death data,we can either get data from there or from the Public Security Bureau in order to check and compare different resource data;if there are missing reports exist in the populationg data and death data,we can use different population missing report rate and death missing report rate to estimate the real state of the region investigated; 4.use death cause inference measuring scale to investigate the cases which are unkown about the death cause;5. to formulate quality control index in order to control the bias;6. using the rate of missing report of the areas of where already carried out the registration of death causes to evaluate the dependablity of household survey and toestimate the real death state of the areas of where not yet carried out the registration of death causes.
