[Selected legal aspects regarding limiting treatment at the end of life : Patient advance directive, proxy and indications].

Respect for the patient's right to self-determination and the professional medical assessment of the (continued) existence of a therapeutic prospect of success of the respective curative intervention ("indication") are the two central reference parameters of every medical therapeutic decision. This is particularly true in cases of a progressive, irreversible, fatal course of the disease. However, the assessment of the presumed will of the patient or the meaningfulness of curative (intensive care) prolongation of life frequently causes difficulties. The law cannot eliminate these doubts in each individual case; it does, however, provide a framework so that factually and ethically justified therapy decisions can be made in each case. In this function, this legal framework-no matter how much it must first be concretized in the respective decision case-demands strict observance. This also includes the most recent change in the law that went into effect on 1 January 2023, through the introduction of a statutory right of (emergency) representation for spouses.
