Physician-assisted death for patients suffering from psychiatric disorders is allowed in the Netherlands under certain circumstances. One of the central problems that arise with regard to this practice is the question of whether it is possible to distinguish between suicidality and a request for physician-assisted death. We set up this study to gain insight into how psychiatrists and general practitioners distinguish between suicidality and physician-assisted death. The data for this study were collected through qualitative interviews with 20 general practitioners and 17 psychiatrists in the Netherlands. From the interviews, we conclude that physicians distinguish three types of death wishes among patients suffering from psychiatric disorders: 'impulsive suicidality,' 'chronic suicidality,' and 'rational death wishes.' To discern between them they evaluate whether the death wish is seen as part of the psychopathology, whether it is consistent over time, and whether they consider it treatable. Some considered physician-assisted death an alternative to a 'rational suicide,' as this was perceived to be a more humane manner of death for the patient and their relatives. We argue that physician-assisted death can be justified also in some cases in which the death wish is part of the psychopathology, as the patient's suffering can be unbearable and irremediable. Physician-assisted death in these cases may remain the only option left to relieve the suffering.
