Background: Following the 2002 enactment of the Belgian law on euthanasia, which requires the consultation of an independent second physician before proceeding with euthanasia, the Life End Information Forum (LEIF) was founded which provides specifically trained physicians who can act as mandatory consultants in euthanasia requests. This study assesses quality of consultations in Flanders and Brussels and compares these between LEIF and non-LEIF consultants. Methods: A questionnaire was sent in 2009 to a random sample of 3,006 physicians in Belgium from specialties likely involved in the care of dying patients. Several questions about the last euthanasia request of one of their patients were asked. As LEIF serves the Flemish speaking community (i.e. region of Flanders and the bilingual Brussels Capital Region) and no similar counterpart is present in Wallonia, analyses were limited to Flemish speaking physicians in Flanders and Brussels. Results: Response was 34%. Of the 244 physicians who indicated having received a euthanasia request seventy percent consulted a second physician in their last request; in 30% this was with a LEIF physician. Compared to non-LEIF physicians, LEIF physicians were more often not a colleague (69% vs 42%) and not a co-attending physician (89% vs 66%). They tended to more often discuss the request with the attending physician (100% vs 95%) and with the family (76% vs 69%), and also more frequently helped the attending physician with performing euthanasia (44% vs 24%). No significant differences were found in the extent to which they talked to the patient (96% vs 93%) and examined the patient file (94% vs 97%). Conclusion: In cases of explicit euthanasia requests in Belgium, the consultation procedure of another physician by the attending physician is not optimal and can be improved. Training and putting at disposal consultants through forums such as LEIF seems able to improve this situation. Adding stipulations in the law about the necessary competencies and tasks of consulting ...
