Information on occupation and industry obtained via an interview prior to death was compared to occupation and industry on the death certificate of 184 colon cancer patients in Utah. The data were coded blindly using a five-digit code. Overall, agreement in the five-digit codes was found for 63 per cent. The industry codes agreed for 67 per cent of the individuals, and the occupation was identical for 68 per cent. Agreement by subjective evaluation of the two data sources, disregarding the five-digit codes, was 73 per cent. There were no differences in agreement of the five-digit codes by age, sex, and county of residence. The number of years worked at the job given by interview was related to agreement. Misclassification occurred in a random manner. It is concluded that the use of death certificates to study the association of occupation and disease is most appropriate for pilot studies.
通过死亡前访谈获得的职业和行业信息与犹他州184名结肠癌患者死亡证明上的职业和行业进行了比较。数据使用五位编码进行盲法编码。总体而言，五位编码的一致性为63%。行业编码对67%的个体一致，职业编码对68%的个体一致。不考虑五位编码，对两个数据源进行主观评估的一致性为73%。按年龄、性别和居住县划分，五位编码的一致性没有差异。访谈给出的工作年限与一致性有关。错误分类是随机发生的。得出的结论是，使用死亡证明来研究职业与疾病的关联最适合于初步研究。
