[Patients' declared intentions and emergency medicine].

Patients with complex medical problems and acute life-threatening diseases deserve a physician with the capability of rapid decision making. Despite an emergency scenario with several unknown or uncertain variables an individual therapeutic plan needs to be defined for each patient. In order to achieve this goal the physician must define medical indications for each form of treatment. Secondly, the patients declared intentions must be respected concerning the previously defined medical indications; however, very often the patients' will is not known. It is very difficult to define an individual treatment plan especially if the patient is not able to adequately communicate. In these situations a custodian is helpful to find out the patients declared intentions towards the current medical situation. If there is no advance directive, family members often have to act as surrogates to find out what therapy goal is best for the individual patient. The patients' autonomy is a very highly respected ethical priority even when the ability for the otherwise usual practice of shared decision-making between physician and patient is compromised. Therefore, in order to do justice to this demanding situation it is necessary to deal with the characteristics of the physician-patient-relatives relationship in emergency medicine.
