Improvement of the quality and comparability of causes-of-death statistics inside the European Community. EUROSTAT Task Force on "causes of death statistics"

Rev Epidemiol Sante Publique. 1998 Dec;46(6):447-56.


Background: Cause-of-death statistics are widely used for comparing health characteristics of European Community (EC) countries. Before attempting to interpret between-country differences, it is essential to assess the biases affecting the comparability of the data. EUROSTAT decided to address globally this problem with the objective to improve the quality and comparability of cause-of-death data within the EC.

Methods: The material is based on a review of results of international comparative cause-of-death studies and on specific inquiries among EC. Both cause-of-death certification and codification practices are analysed. Certification is studied comparing the models of death certificates, the type of information captured, certifiers training and querying practices. The different coding systems are analysed (International classification of diseases (ICD) in use, interpretation of the ICD rules, implementation of automated coding systems).

Results: International studies on comparability of certification and coding practices between countries are rare. These studies are based on certification of cases histories and recoding of samples of death certificates. Recent studies on respiratory diseases, cancers and diabetes outline differences that influenced on the reported level of mortality. The specific EUROSTAT investigation (1997) outline general discrepancies: models of death certificates, nature and amount of information entered, way to establish the diagnosis, degree of consistency of the certification process, autopsy practices, certifiers practices, implementation of ICD-10 and implementation of automated coding systems.

Conclusion: EUROSTAT studies are now focused on causes of death requiring special attention for comparability (e.g. suicide, accidental deaths, drug and alcohol related deaths, unknown and ill-defined causes), on procedures to improve the homogeneity of certifiers training and querying practices, on the effect of the transition to ICD-10. The international model of death certificate recommended by the World Health Organization should be adopted as widely as possible. Uniform complementary information (e.g. surgery, pregnancy, autopsy, place of occurrence of accidental deaths, work accident) should also be adopted. The EUROSTAT investigations must result in definitions of common recommendations and guidelines to EC.
