Spatial clustering of out-of-hospital cardiac arrest in northern France and its association with social deprivation: a population-based registry study

The authors aimed to identify spatial clusters of out-of-hospital cardiac arrest (OHCA) incidence in northern France and investigate the association between these clusters and social deprivation. Their study found significant geographic variability in OHCA incidence, with high-incidence areas correlating with greater socioeconomic deprivation, lower bystander support, and poorer survival outcomes. The findings suggest a need for targeted interventions in these vulnerable communities to improve OHCA care and outcomes.
