Supporting families of patients who die in adult intensive care : A scoping review of interventions

Background
Families who perceive themselves as prepared for an impending death experience reduced psychological burden during bereavement. Understanding which interventions promote death preparedness in families during end-of-life care in intensive care will inform future intervention development and may help limit the burden of psychological symptoms associated with bereavement.

Aim
To identify and characterise interventions that help prepare families for the possibility of death in intensive care, incorporating barriers to intervention implementation, outcome variables and instruments used.

Design
Scoping review using Joanna Briggs methodology, prospectively registered and reported using relevant guidelines.

Data sources
A systematic search of six databases from 2007 to 2023 for randomised controlled trials evaluating interventions that prepared families of intensive care patients for the possibility of death. Citations were screened against the inclusion criteria and extracted by two reviewers independently.

Results
Seven trials met eligibility criteria. Interventions were classified: decision support, psychoeducation, information provision. Psychoeducation involving physician-led family conference, emotional support and written information reduced symptoms of anxiety, depression, prolonged grief, and post-traumatic stress in families during bereavement. Anxiety, depression, and post-traumatic stress were assessed most frequently. Barriers and facilitators to intervention implementation were seldom reported.

Conclusion
This review provides a conceptual framework of interventions to prepare families for death in intensive care, while highlighting a gap in rigorously conducted empirical research in this area. Future research should focus on theoretically informed, family-clinician communication, and explore the benefits of integrating existing multidisciplinary palliative care guidelines to deliver family conference within intensive care.

Implications for clinical practice
Intensive care clinicians should consider innovative communication strategies to build family-clinician connectedness in remote pandemic conditions. To prepare families for an impending death, mnemonic guided physician-led family conference and printed information could be implemented to prepare families for death, dying and bereavement. Mnemonic guided emotional support during dying and family conference after death may also assist families seeking closure.
