The medical statistics in the compulsory accident insurance are conceived as a secondary statistic. It includes both injuries and medical services. Since the Swiss National Accident Insurance Fund started in 1918, there were regular reports about medical statistics. The current statistics of the agency are organized as a sampling statistic. Only disability benefits are covered in toto. The statistical organization permits the identification of single cases in terms of specific characteristics and to analyze them further. The new accident insurance law makes accident insurance obligatory for all persons who are not self-employed. The regulation, included in this law, to record statistics uniformly will hopefully help toward the improvement of medical statistics within the compulsory accident insurance scheme.
