[Rational therapy].

Abstract

In a time of scarce resources, the demand for a rational therapy is important in the present discussion to reform the health system. This article describes rational therapy and introduces practical approaches like drug therapy, evidence-based medicine, and clinical practice guidelines. The development of efficient cost-benefit relations may lead to more rationalization in the health sector. It is important to attain acceptance also among the patients that rationing in the health system is a necessary measure in diagnosis and therapy.
