Assisted dying for persons with mental illness


Short description

Switzerland has the longest history of nonmedicalized assistance in dying, which is considered a civil right even in non-pathological situations. Public debate in Switzerland about the issue of suffering in the context of medical assistance in dying is current and ongoing.

We hold that intolerable suffering is a necessary but insufficient condition for assistance in dying, and criteria should also include decision-making capacity and refractoriness of suffering. We further contend that suffering is a subjective experience that can only be quantified by the patient and cannot be objectively compared across different individuals. On this view, some patients with severe and persistent mental illness, refractory suffering, and preserved decision-making capacity will meet the criteria for medical assistance in dying, and we advocate palliative psychiatric care that includes as much relief of suffering as possible while accepting assistance in dying following conscientious assessment of the criteria.
