A) The tiered medical emergency system should be used adequately; this aim could be attained by (1) information of the public about the "24-h" on-call service of panel doctors; information about the fact that the majority of medical conditions can be treated by panel doctors and that in severe cases a professional and quick referral will be done; information about the fact that self-referral to hospitals may reduce or even obstruct professional resources for the treatment of "real" emergency patients. Target groups are men, younger age groups and people with a higher level of education. (2) information of target groups (elderly people) about the emergency call number 112. (3) information of the public about the national phone number 19222 for patient transports. B) Structural measures such as (1) specific on-call services, (2) improvement of the transparency and reach-ability of panel doctors' on-call services.
