In retrospective epidemiological cohort studies the mortality rate of a cohort exposed to certain agents under investigation is compared to the mortality rate of the general population. In Germany, vital status of the cohort is followed up via local population registries. Cause of death of deceased members of the cohort is obtained from death certificates by local health authorities. Since storage time for death certificates is short in some Federal German states, causes of death cannot be obtained if death occurred before storage deadline. Recently it became possible to obtain the cause of death from regional statistical offices. Initial co-operation has been established with the statistical offices of North Rhine Westphalia and Berlin. For a cohort study in the chemical industry, the initially low proportion of causes of death obtained from local health authorities (44.8 %) was increased by 30 % to 74.0 % after obtaining ICD coded causes of death from two regional statistical offices. Further advantages of this new data source are reduction in duration of inquiry time and of overall cost.
在回顾性流行病学队列研究中，将暴露于某些正在调查的因素的队列的死亡率与一般人群的死亡率进行比较。在德国，通过当地人口登记处对队列的生命状况进行随访。队列中已故成员的死因由当地卫生当局从死亡证明中获取。由于德国一些联邦州死亡证明的存储时间较短，如果死亡发生在存储截止日期之前，就无法获取死因。最近，从地区统计局获取死因成为可能。已经与北莱茵-威斯特法伦州和柏林的统计局建立了初步合作。对于一项化工行业的队列研究，从当地卫生当局获取的死因最初比例较低（44.8%），在从两个地区统计局获取国际疾病分类编码的死因后，这一比例提高了30%，达到74.0%。这个新数据源的其他优势包括查询时间和总体成本的降低。
