[Intensive care for geriatric patients--legal problems]

Treatment of the geriatric patient in the intensive care unit always requires the prior permission of the patient, whose ability to give this must be carefully examined. If the patient is no longer able to do this, a social worker has to act for him/her. This person is appointed by the guardianship court and can agree to risky treatment on the patient's behalf only with the permission of the court. This also applies equally to measures that will constrain the patient's freedom. Only in the case of an emergency may the physician act immediately. The question as to terminating treatment and the considerable need of the will of the patient to do so is discussed. The importance of correct documentation is particularly emphasized.
