A systematic review of the literature on predictors of complicated grief (CG) was undertaken with the aim of clarifying the current knowledge and to inform future planning and work in CG following bereavement. Predictors of CG prior to the death include previous loss, exposure to trauma, a previous psychiatric history, attachment style, and the relationship to the deceased. Factors associated with the death include violent death, the quality of the caregiving or dying experience, close kinship relationship to the deceased, marital closeness and dependency, and lack of preparation for the death. Perceived social support played a key role after death, along with cognitive appraisals and high distress at the time of the death. Inconsistent definitions of CG and measurement tools were noted in the earlier studies reviewed. Limitations identified in the studies included use of cross-sectional designs, heterogeneous samples, high attrition, demographic differences between cases and controls, differences in length of time since death, and differences in types of death experienced. Notwithstanding these limitations, some consistent findings have emerged. Further research into conceptualizations of CG in terms of attachment theory and constructivist and cognitive-behavioral concepts of finding purpose and meaning after bereavement is warranted.

There is a need for health professionals to better understand the concept of palliative care, and factors that contribute to honest, open, authentic and therapeutic relationships of those concerned in the care of the dying child. This will facilitate a better understanding by both parents and their children with cancer, and acceptance of the integration of palliative and supportive care in routine cancer care.

This study explored the experiences and needs of nine parents who had received hospital-based bereavement support following the death of their child from cancer, in Western Australia. Six prominent themes emerged from thematic data analysis: personal grief, personal coping, concern for siblings of the deceased child, hospital bereavement support, community supports and unmet needs. Parents identified the need for more supportive contact from hospital staff during the palliative phase and following the child's death, early provision of information on how to practically and emotionally prepare for the death of their child, contact with other bereaved parents, and formal grief support for siblings. Areas for future research include exploration of parents' wish to become involved in activities to help others, bereavement support for siblings, the level of contact with the hospital unit that may be therapeutically beneficial, and parental behaviors associated with accessing both hospital and community-based bereavement supports.

Care for children and their families should be coordinated by a multidisciplinary team in consultation with children and their families, and should be linked and integrated with the treating hospital in collaboration with community services.
