Danish Society of Insurance Medicine was formed in 1902 as an association between the Danish Society of Accident Insurance and the Danish Society of Life Insurance Medicine, both founded a year before. The purpose of the society is to apply and to further the scientific basis of insurance medicine. The meetings also play a role as a forum for discussions. The members of the society are all working part-time in an insurance company in Denmark (in contrast to many other countries where it is a full-time job). The members are mainly specialists in medicine and surgery. During the first half life of the society nearly all members were high-qualified doctors, i.e. professors and consultants at a university hospital in Copenhagen usually with a doctoral degree. These prominent doctors had a significant influence on insurance medicine in Denmark. The managing directors of the Insurance Companies were invited to the meetings. Many scientific works and textbooks were written on the subject. The society arranges two meetings yearly - one concerning with life insurance and one with accident-insurance medicine. Previously, the question put to the medical adviser was always "Which impairments can still be insured?", but today the question is the opposite "Which impairments are not insurable?" The members have increased to currently 112, still only men, but today the members are younger, comprise fewer professors and fewer with a doctoral degree. During the last 6 years, all interested members in the insurance companies have been invited to the meetings, providing a broader input for the discussions. The topic of the meeting is of current interest: new laws or a new treatment of a disease (medication, surgery) which has been introduced. One to three speakers open the meeting, followed by a discussion. The meetings are always concluded with a light meal and a glass of wine, in earlier days also with cigars and Danish schnaps. 190 meetings have been held during the last 100 years. Often the speakers are members of the society. In the future the Danish Society of Insurance Medicine will face new challenges as regards to the communication of knowledge about new diseases and new treatments in the light of with biostatistics and new insurance products.
