title: [Hidden statistics of traffic accidents].
abstract: Only 19% of the 3,071 injured persons who were treated in the casualty department of Odense Hospital following traffic accidents in 1987 could be found again in the police registers of traffic accidents from the same region. All of the registrations from the police registers from the central region could be found again in the casualty department. In 1971, the corresponding coverage was 36%. The degree of coverage is particularly low for single bicycle accidents, other bicycle accidents, other single accidents and the hours immediately after midnight. Considerable disagreement exists concerning registration of the use of safety belts and crash helmets. In Odense, the municipal road authorities utilize the localization of the accidents reported by the casualty department. The decrease in the degree of coverage is due mainly to an increasing proportion of bicycle accidents. Where casualties require admission to hospital, the coverage is approximately 75%. This has remained unchanged throughout the years and it is therefore suggested that this proportion should be employed as indicator of the effect of the majority of prophylactic measures. In addition, proposals are made for simplification of the police registration forms.
