[Insurance and preventive medicine].

Not only do insurance companies have to pay in case of death, injuries or disease, they are also concerned with their prevention. This is particularly true for the "Swiss National Accident Insurance Fund" (Caisse nationale suisse d'assurance en cas d'accidents--(CNA): for them the prevention of work related accidents and occupational diseases is required by law. Preventive activities in this area are very promising. The progress in the sickness insurance programmes for preventive medicine in the general population has, however, not been as successful. To date, the legislation denies payment for preventive medical care. Why is there this difference? In the case of accidents and occupational diseases, the cause of the pathologies are for the most part exogenous and develop in well known and controlled environments. In the case of disease or invalidity in the general population, the factors are in a large part endogenous and therefore very difficult to supervise, as they develop in much more complex and uncontrolled environments. Nevertheless progress has been done in this field as well. At present, some selected scientifically proven preventive examinations could be included in insurance programmes as part of a general plan and with strict quality control of laboratory findings.
