Telemedicine-Assisted vs Conventional Telephone Instruction in Cardiopulmonary Resuscitation

N/A NCT07546474 Kind: NA Apr 22, 2026

Abstract

Out-of-hospital cardiac arrest (OHCA) is a life-threatening emergency where early cardiopulmonary resuscitation (CPR) by bystanders can significantly improve survival. Emergency dispatchers often guide bystanders to perform CPR over the phone, a method known as dispatcher-assisted CPR (DA-CPR). While this approach has increased bystander CPR rates worldwide, it relies on voice communication only, which may limit the dispatcher's ability to assess the situation and guide CPR effectively.

With advances in telecommunication technology, video-based communication has become more widely available. Telemedicine-assisted CPR (TA-CPR) allows dispatchers or emergency medical providers to see the patient and the rescuer through a live video call, potentially improving CPR performance by providing real-time visual feedback. However, evidence on whether this approach improves outcomes in real-world emergency medical service (EMS) systems is still limited.

This study aims to compare the effectiveness of TA-CPR with conventional DA-CPR in adult patients with suspected non-traumatic OHCA. The study is designed as a pragmatic cluster-randomized controlled trial conducted within a hospital-based EMS system in Bangkok, Thailand. Instead of randomizing individual patients, the CPR instruction protocol is assigned by month (cluster randomization). During each month, all eligible patients receive either the TA-CPR protocol or the DA-CPR protocol.

In both groups, CPR instructions are first pr...
