Incidence and Outcomes After Out-of-Hospital Cardiac Arrest at Train Stations in Denmark.

Background: Following international guidelines, communities have deployed automated external defibrillators at train stations without substantive evidence.

Methods And Results: We geocoded public out-of-hospital cardiac arrests (OHCAs) (2016-2020), automated external defibrillators, and train stations. The stations were divided into the following groups according to passenger flow: 1 (0-499), 2 (500-4999), 3 (5000-9999), and 4 (>10 000) passengers per day.

Volunteer Responder Interventions in Out-of-Hospital Cardiac Arrest in Urban, Suburban, and Rural Areas.

Background: Patients with out-of-hospital cardiac arrest (OHCA) in rural areas experience longer emergency response times and have lower survival rates compared with patients in urban areas. Volunteer responders might improve care and outcomes for patients with OHCA specifically in rural areas. Therefore, we investigated volunteer responder interventions based on the degree of urbanization.

Community intervention to improve defibrillation before ambulance arrival in residential neighbourhoods with a high risk of out-of-hospital cardiac arrest: study protocol of a cluster-randomised trial (the CARAMBA trial).

Introduction: In Denmark, multiple national initiatives have been associated with improved bystander defibrillation and survival following out-of-hospital cardiac arrest (OHCA) in public places. However, OHCAs in residential neighbourhoods continue to have poor outcomes. The Cardiac Arrest in Residential Areas with MoBile volunteer responder Activation trial aims to improve bystander defibrillation and survival following OHCA in residential neighbourhoods with a high risk of OHCA.
