Efficacy of Bystander Intervention Program in Nursing Students

This randomized controlled trial evaluated the effectiveness of a bystander intervention program for dating violence among nursing students. The study was conducted with second-year nursing students at Istanbul University-Cerrahpaşa Florence Nightingale Faculty of Nursing. A total of 84 students were randomized to the intervention and control groups. Due to missing data from one participant in the control group, 83 students were included in the final analysis (intervention group, n=42; control group, n=41). Participants were allocated to the groups using computer-generated randomization. The intervention group received the Bystander Intervention Program, which was developed based on the Bystander Behavior Model and the Theory of Planned Behavior and adapted to the cultural and institutional context. The control group received a single 90-minute educational session on dating violence during the study period. After completion of all outcome assessments, participants in the control group were also offered the Bystander Intervention Program for Dating Violence. Data were collected face-to-face using an Individual Information Form, the Bystander Efficacy Scale, the Intention to Help Scale-Short Version, the Bystander Behavior Scale, and a Program Evaluation Form. Bystander efficacy and intention to help were assessed at baseline, immediately after the intervention, and at two-month follow-up. Bystander behavior was assessed at baseline and at two-month follow-up.

A Study on the Impact of a New Canton-Wide First Responder System in Zug, Switzerland, on Survival After Adult Cardiac Arrest-Examining Early Life-Saving Organized Help, Fast Defibrillation, and Improved Outcomes for Out of Hospital Cardiac Arrest

REVIVE Zug: Improving Emergency Response for Out-of-Hospital Cardiac Arrest Out-of-hospital cardiac arrest (OHCA) represents one of the most time-critical medical emergencies, where rapid recognition and immediate intervention are decisive for survival and neurological outcome. Early activation of emergency services, prompt initiation of cardiopulmonary resuscitation, and rapid defibrillation using automated external defibrillators (AEDs) are key components of the chain of survival. In many regions, organized First Responder systems-such as fire services, police forces, and trained lay responders supported by dispatcher-assisted instructions-arrive at the scene before emergency medical services (EMS) and initiate life-saving measures. Evidence from multiple EMS systems indicates that the early involvement of First Responders is associated with higher rates of return of spontaneous circulation (ROSC) and improved survival to hospital discharge with favorable neurological outcomes. Regions with well-established First Responder networks consistently report better OHCA outcomes compared with regions without such systems. In the canton of Zug, a comprehensive First Responder system has recently been implemented alongside an established hybrid EMS response model. In this system, resuscitation efforts are led either by an Emergency Physician (EP) or by a highly trained Critical Care Paramedic (CCP), depending on operational availability. Both roles operate within clearly defined competencies and provide the full scope of advanced prehospital care. This hybrid leadership model offers a unique opportunity to examine whether the professional background of the team leader influences resuscitation outcomes in real-world clinical practice. The REVIVE Zug study aims to evaluate the impact of the canton-wide First Responder system on outcomes following OHCA. Key outcomes of interest include ROSC rates, hospital admission after cardiac arrest, the occurrence of shockable rhythms at EMS arrival, and outcomes achieved before EMS arrival. In addition, the study explores whether team leadership by an EP or a CCP is associated with differences in resuscitation outcomes. Further analyses focus on time intervals within the chain of survival, such as time from cardiac arrest to arrival of organized help and time to first defibrillation, as well as on event timing and basic demographic characteristics. The study is based on anonymized data from established EMS quality registries and the national Swiss Reca database. By comparing OHCA cases before and after implementation of the comprehensive First Responder system, the project seeks to provide robust, practice-oriented evidence to inform future development of prehospital emergency care systems in Switzerland and comparable settings.
