“…Up to 29% of palliative care patients have been identified as experiencing depression or other mood disorders at some time during the palliative phase (Durkin et al, 2003;Lloyd-Williams et al, 2004;Miovic & Block, 2007;Teunissen et al, 2007) and it has been shown with cancer patients in the palliative care stage, that previously mentally healthy individuals become psychologically vulnerable as the disease progresses (Dudgeon et al, 1995;Mazzocato et al, 2000;Akechi et al, 2004). A clinical diagnosis of depression in terminally ill cancer patients has been significantly associated with a desire for hastened death and can have an adverse effect on their quality of life (Breitbart et al, 2000;Tiernan et al, 2002). A recent study showed that among patients in Oregon who requested a physician's aid in dying, one in four had clinical depression (Ganzini et al, 2008) and a Swiss study found that in 114 cases of assisted suicide, 27% had been observed by the assessor to be depressed (Bosshard et al, 2008).…”
