Authors' conclusion
New support interventions for bystanders involved in OHCA are emerging, particularly in Western countries. The most common component of these interventions is information-giving, with the majority also providing debriefing and psychological support. However, more research is needed on the most effective ways to promote these interventions and on the effects of these interventions on outcomes important to bystanders.
