"When life was ended without the explicit request of the patient, there had been discussion about the act or a previous wish of the patient for the act in 60.0% of patients, as compared with 26.5% in 2001. In 2005, the ending of life was not discussed with patients because they were unconscious (10.4%) or incompetent owing to young age (14.4%) or because of other factors (15.3%). Of all cases of the ending of life in 2005 without an explicit request by the patient, 80.9% had been discussed with relatives. In 65.3% of cases, the physician had discussed the decision with one or more colleagues"
So, part of this is due to the fact that the law states that doctors must check that the patient consents _now_ with the choice. A written statement that, for example, one doesn't want to live on with Alzheimer's when one has reached a well-described state is not sufficient.
