Abstract

Background: People receiving palliative care have complex, wide-ranging, and changing needs, not just physical distress, but also psychosocial, practical, and spiritual. Influences on complexity in palliative care are different among healthcare providers and may depend on diverse aspects of the patient’s condition, time, and environment. Therefore, this study aimed to integrate and describe the perspective of complexity in palliative care. Methods: We used an integrative review, which is a method of compiling, summarizing, and analyzing existing insights from previous studies. We conducted an electronic literature search in MEDLINE (Ovid), PsycINFO (EBSCOhost), Web of Science Core Collection, and CINAHL (EBSCOhost), examining literature from May 1972 to September 2020 and updated in December 2020. Subsequently, synthesis without meta-analysis of the findings was completed. Results: We identified 32 peer-reviewed articles published in English. The included 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 identified 29 that influenced complexity in palliative care, 25 perceptions of the patient, including background and physical, psychological, social, and spiritual; two perceptions in the healthcare setting; and two perceptions in the socio-cultural setting. Above all, the perceptions of complexity in palliative care included younger age, prognosis, and spirituality. In addition, we added the identified perceptions of complexity with references to the complexity model in palliative care. Conclusions: Although this review was limited in its search strategy and some data sources may have been overlooked, it still provided perceptions that influenced complexity in palliative care. These complex influencing perceptions are necessary for patients to receive appropriate palliative care at the right time and for health care providers to conduct a multi-disciplinary team approach. Furthermore, longitudinal prospective data are needed to examine the changes and relationships among complexity over time.
