Prevalence Rate of Depression in Palliative and Hospice Care: A Narrative Review

Depression is a common but not universal experience among individuals receiving hospice and palliative care. Though much research exists on depression in this population, there is little consensus on the actual prevalence rate, with estimates varying drastically. This is due, in part, to non-standardized definitions of what constitutes depression, variance based on assessment methods and tools, and the presence of somatic symptoms that may be due to physical illness and not depression, thus distorting the prevalence rate in this population. Depression can cause significant negative consequences for individuals and those who care for them, robbing them of precious time, increasing suffering, and decreasing overall quality of life. This narrative review seeks to understand depression's prevalence among people living with severe and life limiting illness based on the existing literature.
