Purpose of patient information

The basic principle is that only the person on whom the medical treatment is performed can give a legally effective consent to an intervention. Since information is an indispensable prerequisite for such consent, the person concerned must also be informed.
In principle, this also applies to minors or incapacitated persons, provided that they are capable of judgement. In the case of incapacity to judge, it is the legal representative who gives consent to the intervention. In the absence of a legal representative, the patient’s wider environment (relatives) must be involved and an attempt made to weigh up the objective interests and define a presumed will of the patient.
