Technological advancements, particularly in telehealth services, have opened up new possibilities for improving the quality and accessibility of health care [The existing T-CPR protocols for lay responders primarily focus on single-rescuer CPR and lack guidance on promoting collaboration among multiple lay responders to enhance prearrival care. Studies have shown that 43.1% of OHCA rescue events involve the presence of multiple lay responders at the scene [Introducing a team-based tele-instruction plan for telecommunicators could serve as a cost-effective yet highly beneficial strategy to optimize the effectiveness of team cooperation among multiple lay responders. This plan would ensure the consistent delivery of high-quality CPR for patients who experience OHCA. In contrast to periodic mass training initiatives for team-based CPR, implementing the team-based tele-instruction plan through telecommunicators leverages its widespread reach to effectively instruct a large number of lay responders, resulting in enhanced resuscitation quality. Hence, this study aimed to develop an innovative team-based tele-instruction tool with the aim of expanding the use of telehealth emergency services. We evaluated the effectiveness and feasibility of this tool through a randomized controlled simulation trial and semistructured interviews.
