Abstract
Background
Globally, work-related deaths (injuries and diseases) are a major social and public health problem. Register data on fatal occupational injuries in high-income countries may be considered to have high quality, especially when reporting is mandatory and regulated by law. We aimed to assess the accuracy of work-related injury death statistics in Norway, with reference to the Labour Inspection Authority and three other on-going registration systems (the cause-specific mortality register, the register for governmental compensations, and the register for insurance companies).
Methods
In this register-based study, we used the capture-recapture technique to adjust for undercounting. We investigated whether the capture-recapture method using two or three sources gave a valid estimate of fatal occupational injuries as compared with the number of cases identified in four registers administrated by the Norwegian Labour Inspection Authority, Statistics Norway, the Labour and Welfare Administration, and Finance Norway. The inclusion criteria were fatal unintentional injuries among residents of Norway between 2000 and 2003 that occurred while working for income in private and public land-based industries. We obtained ethical and legal approvals.
Results
In a period of four years (2000−2003), the Labour Inspection Authority registered 171 occupational injury deaths among residents employed in land-based industries. Two combinations of data sources gave capture-recapture estimates of 246 [95% CI 216; 279] and 265 [95% CI 234; 299] deaths. In total, 246 cases were identified in the four registration systems, which was 44% higher than the number of deaths registered by the Labour Inspection Authority. The Labour Inspection Authority had the most complete register out of the four registration systems.
Conclusions
The capture-recapture method used on two overlapping data sources gave highly valid estimates of the total deaths. We demonstrated the existence of significant weaknesses in the registration systems in a country considered to have high-quality register data.
在全球范围内,与工作有关的死亡(伤害和疾病)是一个重大的社会和公共卫生问题。高收入国家关于致命职业伤害的登记数据可被认为具有高质量,特别是在报告是强制性和受法律管制的情况下。我们的目的是评估挪威工伤死亡统计数据的准确性,参照劳动监察局和其他三个正在进行的登记系统(特定原因死亡登记、政府赔偿登记和保险公司登记)。方法在这项基于记录的研究中,我们使用捕获-再捕获技术来调整漏记。我们调查了使用两个或三个来源的捕获-再捕获方法是否给出了致命职业伤害的有效估计,与由挪威劳动监察局、挪威统计局、劳工和福利管理局和挪威财政部管理的四个登记册中确定的病例数量相比。纳入标准是2000年至2003年期间挪威居民在私营和公共土地工业中为赚取收入而工作时发生的致命意外伤害。我们获得了道德和法律上的批准。结果在四年期间(2000 - 2003年),劳动监察局在陆地工业就业的居民中登记了171人因职业伤害死亡。两种数据来源的组合给出了捕获-再捕获的估计值为246 [95% CI 216;279]和265 [95% CI 234;299]死亡。在四个登记系统中总共发现了246起案件,比劳动监察局登记的死亡人数高出44%。在四个登记系统中,劳工视察局拥有最完整的登记册。结论在两个重叠数据源上使用的捕获-再捕获方法对总死亡人数给出了高度有效的估计。我们证明,在一个被认为拥有高质量登记数据的国家,登记系统存在重大弱点。
