ContextThough palliative sedation has been recognized as an acceptable practice in Canada for many years now, there is a lack of clinical research and guidelines pertaining to its use as a treatment of existential refractory symptoms in the terminally ill.ObjectivesThis scoping review aimed to survey the literature surrounding palliative sedation and existential suffering and to inform research, policy, and practice.MethodsTo address the main research question: Is palliative sedation an acceptable intervention to treat existential refractory symptoms in adults aged 65 and older? a scoping review following Arksey and O'Malley's framework was performed, spanning electronic databases of the peer reviewed and grey literature. Articles were screened for inclusion, and a thematic content analysis allowed for a summary of key findings.ResultsOut of 427 search results, 71 full text articles were obtained, 20 of which were included. Out of these articles, four themes were identified as key findings. These included: (1) Ethical considerations; (2) The role of the health care provider; looking specifically at the impact on nurses; (3) The need for multidisciplinary care teams; and (4) Existential suffering's connection to religiosity and spirituality.ConclusionPalliative sedation to treat existential refractory symptoms was labelled a controversial practice. A shortage of evidence-based resources limits the current literature's ability to inform policy and clinical practice. There is a need for both qualitative and quantitative multi-center research so health care professionals and regional-level institutions have firm roots to establish proper policy and practice.
