Family presence during adult resuscitation from cardiac arrest: A systematic review

Aim: Objective: To conduct a systematic review of the published evidence related to family presence during adult resuscitation from cardiac arrest. Methods: This review, registered with PROSPERO (CRD42021242384) and reported according to PRISMA guidelines, included studies of adult cardiac arrest with family presence during resuscitation that reported one or more patient, family or provider outcomes. Three databases (Medline, CINAHL and EMBASE) were searched from inception to 10/05/2022. Two investigators screened the studies, extracted data, and assessed risks of bias using the Mixed Method Appraisal Tool (MMAT). The synthesis approach was guided by Synthesis Without Meta-Analysis (SWiM) reporting guidelines and a narrative synthesis method. Results: The search retrieved 9,459 citations of which 31 were included: 18 quantitative studies (including two RCTs), 12 qualitative studies, and one mixed methods study. The evidence was of very low or low certainty. There were four major findings. High-certainty evidence regarding the effect of family presence during resuscitation on patient outcomes is lacking. Family members had mixed outcomes in terms of depression, anxiety, post-traumatic stress disorder (PTSD) symptoms, and experience of witnessing resuscitation. Provider experience was variable and resuscitation setting, provider education, and provider experience were major influences on family presence during resuscitation. Finally, providers reported that a family support person and organisational guidelines were important for facilitating family presence during resuscitation. Conclusion: The effect of family presence during resuscitation varies between individuals. There was variability in the effect of family presence during resuscitation on patient outcomes, family and provider outcomes and perceptions.
