The practical application of rational concepts will be possible in the
health care system if two conditions will be met. The legal framework
has to fit these goals and new strategies are to establish. The new s
trategies will be needed to identify from the huge amount of data ''ev
idence'' which will support the medical progress. Evidence-Based Medic
ine (EBM) offers these strategies. Modifications of our conventional p
rocedures are necessary to establish EBM: the conditions of clinical a
ctions, the definitions of goals of medical training, the rational of
clinical decisions and the continued medical education.
