Comparing fatal occupational accidents in Denmark and Sweden 1993–2012

Background: Denmark and Sweden are in many respects two very similar countries with similar welfare state systems and work environment authorities. Nevertheless, marked differences in the incidence of fatal occupational accidents have been found in earlier comparisons of the two countries. Aims: To investigate differences in the incidence of fatal occupational accidents in the period from 1993 to 2012 to establish to what extent characteristics of the deceased can explain some of the difference between the two countries. Methods: Analyses of the accident registers of the two countries' national work environment authorities with supplemental linkages to official registers on employment status are used to determine the incidence of fatal occupational accidents for different groups. The analysis is based on 2375 accidents (1068 in Denmark and 1307 in Sweden) over the period of 20 years. Poisson regression is used to derive incidence rates over time for specific groups. Results: In the study period, the incidence of fatal occupational accidents decreased in both countries (incidence rate ratio [IRR]: 0.95), although the incidence was on average higher in Denmark (IRR: 1.20) and grew larger over time. This difference did not disappear after adjusting for age, sex and industry among the deceased (IRR: 1.12). Conclusions: The incidence of fatal occupational accidents was slightly higher in Denmark in the entire period. The difference could not be explained completely by sociodemographic differences or differences related to the labour market structure in the two countries, i.e. other factors (e.g. cultural) may play a role in producing the difference.
