This study evaluated the concordance between occupation and industry listed on death certificates with actual work history information for a group (n = 5,882) of long-term (10 years or more) workers at a chemical company. Match rates were calculated as the percent of death certificate occupation and company entries that were confirmed by work history data using 3-digit 1980 U.S. Census Bureau group codes. The concordance rate for industry differed by employment status at death: employed, 94.9%; inactive, 30.8%; and retired, 91.1%. Concordance on occupation was analyzed for employed (n = 467) and retired (n = 932) subjects who had computerized work histories (randomly done prior to the study) and who had matched on the company on the death certificate. Concordance ranged from 0 to 50% for the first job, to 50 to 70% for the last job, longest job, and longest job in the last 10 years of company employment. The most consistent predictor of concordance was job duration. Misclassification was reviewed by occupational category. Results from this and other investigations lead to the inevitable conclusion that usual occupation data from death certificates are grossly inadequate for studies of occupational risks.
本研究评估了一家化工公司一组长期（10年或更长时间）工人（n = 5882）死亡证明上列出的职业和行业与实际工作经历信息之间的一致性。匹配率计算为使用1980年美国人口普查局3位数分组代码，工作经历数据确认的死亡证明职业和公司条目的百分比。行业的一致性率因死亡时的就业状况而异：在职为94.9%；非在职为30.8%；退休为91.1%。对有计算机化工作经历（在研究之前随机进行）且死亡证明上公司匹配的在职（n = 467）和退休（n = 932）受试者的职业一致性进行了分析。第一份工作的一致性范围为0至50%，最后一份工作、最长工作以及公司就业最后10年中的最长工作的一致性范围为50至70%。一致性最一致的预测因素是工作时长。按职业类别对错误分类进行了审查。本研究及其他调查的结果不可避免地得出这样的结论：死亡证明上的通常职业数据对于职业风险研究来说严重不足。
