目的：目的是调查是否有可能通过官方死亡证明来评估心血管疾病社区干预方案中的死亡模式。研究方法：对于干预地区（Norsjo）的所有死者，将官方死亡证明的准确性与Vasterbotten其他地区的匹配对照进行了比较。将官方死亡原因与新证书进行比较，新证书基于最近的临床记录，由三位作者发布，并由其中一位作者编码，因此所有四位作者均设盲。结果如下：在“心血管疾病”（CVD）和重新评估的证书中，官方的潜在死亡原因之间的一致程度在Norsjo和Vasterbotten的其他地区之间没有差异。在章节水平上的一致性分别为87%和88%，但在4位数水平上分别仅为55%和55%。重新分类导致Norsjo和V sterbotten其余地区的“心血管死亡”减少1%。结论：死亡原因重新分类的分歧是平等的，但在两个方向上都很大。在小型社区干预项目中，应谨慎使用官方死亡证明来评估心血管疾病，并仅限于章节水平和总人口。
Aim: The aim was to investigate the possibility to evaluate the mortality pattern in a community intervention programme against cardiovascular disease by official death certificates. Methods: For all deceased in the intervention area (Norsjo), the accuracy of the official death certificates were compared with matched controls in the rest of Vasterbotten. The official causes of death were compared with new certificates, based on the last clinical record, issued by three of the authors, and coded by one of the authors, all four accordingly blinded. Results: The degree of agreement between the official underlying causes of death in "cardiovascular disease" (CVD) and the re-evaluated certificates was not found to differ between Norsjo and the rest of Vasterbotten. The agreement was 87% and 88% at chapter level, respectively, but only 55% and 55% at 4-digit level, respectively. The reclassification resulted in a 1% decrease of "cardiovascular deaths" in both Norsjo and the rest of V sterbotten. Conclusions: The disagreements in the reclassification of cause of death were equal but large in both directions. The official death certificates should be used with caution to evaluate CVD in small community intervention programmes, and restricted to the chapter level and total populations.
