[Methods for cost-effectiveness evaluation of intensive care].

Intensive care costs are a challenge to the health care system. Because of a political strategy aiming at competition as well as the documentation of treatment quality, cost-effectiveness evaluations are important in order to clarify the association between quality and the costs of treating critically-ill patients. The context of cost-effect analyses is important. Most studies apply the hospital's perspective based on surrogate markers such as organ failure and length of stay as a replacement for health status evaluation in the context of society. The treatment of critically-ill patients aims at improved health. Cost-effectiveness analyses should therefore include quality variables in that the healthcare system is an integral and inseparable part of society.
