Psychosocial factors affecting the bereavement experience of relatives of palliative-stage cancer patients: a systematic review

Abstract

Background Cancer is one of the leading causes of death worldwide and a cancer death is a major risk factor for pathological bereavement. This systematic review of the literature aimed to identify biopsychosocial and existential determinants specific to the palliative phase of cancer that influence the grieving experience of the caregiving relative. Method A systematic review of the literature was conducted without language or time restrictions. The Cairn, Cochrane Library, PubMed, PsycArticle, PsychInfo, Psychology and Behavioral Sciences Collection databases were explored. All studies assessing pre- and post-death measures and focusing on friends and relatives caring for adults with cancer in palliative care services were included in the review. Results Out of 645 articles identified, 18 full text studies were finally included in our systematic review of the literature. Many factors specific to the cancer palliative phase were identified as influencing the bereavement experience of caregivers, with factors relating to: 1) the caregiver (e.g. social support, psychological burden, preparation for loss, action and discussion related to death); 2) the patient (e.g. denial or acceptance); 3) the interactions between patient and their caregivers (e.g. tensions, communication difficulties, and presence at the time of death); and 4) the end-of-life context. The caregiver's grief experience can be described by the following terms: typical and pathological grief, anxiety, depression, guilt, psychological distress, post-traumatic stress disorder and post-traumatic growth, and life satisfaction. Conclusions Many contextual, sociodemographic, dispositional and transactional factors specific to the palliative cancer phase are involved in the caregiver's grieving experience. Avenues for reflection and recommendations are proposed including supporting communication and patient-relative relationships, evaluating the nature and degree of functionality of coping strategies, strengthening the robustness of methodologies, considering impact of COVID-19, and new lines of enquiry for research.

The caregiver’s perspective on end-of-life inpatient palliative care: a qualitative study

“…End-of-life conversations are often avoided due to fears of stirring up emotional distress and the perceived need to keep hope alive through engaging in positive conversations [ 52–54 ]. However, the absence of end-of-life communication has been shown to affect the bereavement process negatively and lead to pathological mourning [ 55 ], while – paradoxically - death-talk is associated with acceptance of death and relationship quality. According to Wanget al [ 56 ], death-talk leads to a psychological state of death awareness and death acceptance for both patients and caregivers.…”

Posttraumatic growth and related factors among relatives, caring for cancer patients. Systematic review (Part 1)

“…Сведения ПТР у родственников, опекающих взрослых больных, в литературе встречаются значительно реже. В то же время систематические обзоры, включающие метаанализ качественных и количественных исследований, посвященных изучению опыта и переживаний родственников в ситуации болезни взрослого члена семьи отражают, что тема ПТР неизменно возникает в процессе ухода за больным [33,39,57,64,66].…”
