Complexity In The Context of Palliative Care: A Scoping Review
Abstract Background: Understanding the factors of complexity of patients in palliative care is very important for healthcare providers in addressing the care needs of their patients. However, the healthcare providers’ perception of the factors of complexity in palliative care lacks a common understanding. This study aimed to determine the scope of research activities and specific factors of complexity in the context of palliative care.Methods: A scoping literature review was performed, following the methods described by the Joanna Briggs Institute. We conducted an electronic literature search in MEDLINE (Ovid), PsycINFO, Web of Science Core Collection, and CINAHL, examining literature from May 1972 to 2020.Results: We identified 32 peer-reviewed articles published in English before 2020. The target literature mainly originated in Europe and the United States. The research methods included quantitative studies (n=13), qualitative studies (n=12), case studies (n=3), and reviews (n=4). We reviewed 32 studies and summarized the factors of complexity into three levels: the patient’s level, the healthcare setting level, and the socio-cultural landscape level. We identified factors affecting patient-specific complexity, including sex, race, age, living situation, family burden, resources, treatment, decision-making, communication, prognosis, disease, and comorbidity/complexity. Other factors identified as contributing to patient complexity were the interaction of physical, psychological, social, and spiritual categories, as well as the healthcare providers’ confidence and skills, and the socio-cultural components.Conclusions: This scoping review shows specific factors of complexity and future challenges in the context of palliative care. Future research should include the factors of complexity identified in this review and conduct longitudinal studies on the interactions among them. In addition, it is necessary to examine specific complexity factors in patients from various social and ethnic backgrounds.
