目的了解成都市死因登记工作中死亡病例漏报情况,用捕获-再捕获计算方法校正人群死因死亡率数据。方法采用多阶段随机整群抽样方法抽取在成都市6个行政村(居委会),通过入户调查的方法获得2013-2014年居民死亡数据,与同期医学死亡登记系统电子数据库核对,统计漏报率。结果 2013-2014年成都市报告粗死亡率7.39‰,利用捕获-再捕获统计方法,计算校正漏报率7.41%,校正报告粗死亡率为7.98‰。结论成都市死因监测漏报率较低,在全人群的范围内能合理反映全市居民的死因模式。
Objective To understand the missed cases of deaths in the death cause registration in Chengdu, and to use the capture-recapture calculation method to correct the mortality data of the death causes. Methods A multi-stage random cluster sampling method was used to collect data from 6 administrative villages (neighborhood committees) in Chengdu. Resident death data from 2013 to 2014 were obtained through the household survey method. The data were compared with the electronic database of the medical death registration system at the same time. . Results In 2013-2014, Chengdu City reported a crude mortality rate of 7.39‰. Using the capture-recapture statistics method, the calculated missed report rate was 7.41%, and the corrected report crude death rate was 7.98‰. Conclusion The missing rate of death cause monitoring in Chengdu is low, and it can reasonably reflect the mode of death of the residents in the whole population.
