“…Introduction to death, palliative care, and hospice. Eighteen studies (13 studies for health professionals, two for family caregivers, two for volunteers, and one for indigenous community carers) covered the following aspects: definitions of palliative care, hospice, and death in medical and legal terms [25,26,27,28,29,30,31,32,33,34,35,36]; core hospice concepts such as supporting not only the patient but also caregivers and interdisciplinary practices [37]; the theory of 'circle of care', philosophies, and principles of palliative care [38,39,40]; death as a developmental story [41]; and trajectories of various end-stage diseases [42]. While the content of this theme largely followed the medical and legal terms of death, the PCE for Northern Plains American Indians (NPAIs) delivered the program by consulting with the targeted indigenous community and employed indigenous language to introduce the concept of death.…”
