Background The death of a child can have a profound impact on critical care nurses, shaping their professional practice and personal lives in diverse, enduring ways. Whilst end-of-life care is recognised as a core component of critical care nursing practice and a research priority, evidence about nurses’ experiences after death in neonatal and paediatric intensive care is poorly understood.

Research question What is the experience of the nurse after death of a patient in neonatal and/or paediatric intensive care?

Method Following registration with Open Science Framework, an integrative review of the empirical literature was undertaken. A combination of keywords, synonyms, and Medical Subject Headings was used across the Cumulative Index Nursing and Allied Health Literature (CINAHL) Complete, Medline, APA PsycInfo, Scopus, and Embase databases. Records were independently assessed against inclusion and exclusion criteria. All included papers were assessed for quality. Narrative synthesis was used to analyse and present the findings.

Findings From 13,018 records screened, 32 papers reporting primary research, representing more than 1850 nurses from 15 countries, were included. Three themes were identified: (i) postmortem care; (ii) caring for bereaved families; and (iii) nurses’ emotional response, which includes support for nurses. Nurses simultaneously cared for the deceased child and family, honouring the child and child–family relationship. Nurses were expected to provide immediate grief and bereavement support to families. In response to their own emotions and grief, nurses described a range of strategies and supports to aid coping.

Conclusion Recognising neonatal and paediatric critical care nurses' experience after death is key to comprehensively understanding the professional and personal impacts, including the shared grief of a young life lost. Enabling nurses to acknowledge and reflect upon their experiences of death and seek their preferred supports is critically important. Thus, ensuring organisational and system processes similarly align with nurses’ preferences is key.
