The early commencement of effective resuscitation is of fundamental importance for the survival of individuals experiencing out-of-hospital cardiac arrest. In such circumstances, video-assisted guidance by the dispatcher has been demonstrated to be advantageous for the recognition of cardiac arrest and the improvement of CPR quality. The present study investigates the effectiveness of a brief training program for control center dispatchers in the recognition of common errors during simulated resuscitation.
The study was approved by the local ethics committee and registered at the German Clinical Trial Register on 27th of February 2024 (Registration number: DRKS00032661) prior to inclusion of the first participant. Within a two-armed group study design, paramedics and emergency physicians were randomly assigned to either an experimental group (n = 44) or a control group (n = 44). The experimental group was initially exposed to a targeted brief training aimed at enhancing the recognition of excessively deep chest compression depth. All participants evaluated 42 distinct video sequences showing seven typical errors during CPR. The shown CPRs were simulated on a training manikin and the videos were evaluated by the participants under laboratory conditions. The primary endpoint was the accurate evaluation of the presented videos with too deep compression depth in a laboratory setting.
A total of 3696 video sequences were evaluated. The experimental group demonstrated a significantly higher recognition rate for too deep chest compressions compared to the control group (87.9% vs. 59.2%, p < 0.001). With regard to the remaining errors, no significant differences were observed between the study groups. Overall, 2861 of the 3696 videos (77.7%) were correctly classified. The proportion of correctly classified videos was significantly higher in the experimental group compared to the control group (79.8% vs. 75.6%, p = 0.003), indicating a statistically significant effect of the intervention.
The identification of chest compressions with too deep compression depth in a video of simulated CPR was found to increase significantly in evaluators who had undergone a brief training course.
The trial was registered in the German Clinical Trial Register "BfArM - Deutsches Register Klinischer Studien (DRKS)" under the registration number DRKS00032661.
对于院外心脏骤停患者的生存而言，尽早开始有效的复苏至关重要。在这种情况下，调度员通过视频辅助指导已被证明有利于识别心脏骤停并提高心肺复苏质量。本研究调查了针对控制中心调度员的简短培训计划在模拟复苏过程中识别常见错误的有效性。
本研究经当地伦理委员会批准，并于2024年2月27日在德国临床试验注册中心注册（注册号：DRKS00032661），之后纳入第一名参与者。在双臂组研究设计中，护理人员和急诊医生被随机分配到实验组（n = 44）或对照组（n = 44）。实验组最初接受了旨在提高对过度深度胸外按压深度识别能力的针对性简短培训。所有参与者评估了42个不同的视频序列，这些序列展示了心肺复苏过程中的七种典型错误。所展示的心肺复苏操作是在训练人体模型上模拟的，视频由参与者在实验室条件下进行评估。主要终点是在实验室环境中对呈现的胸外按压深度过深的视频进行准确评估。
共评估了3696个视频序列。与对照组相比，实验组对胸外按压过深的识别率显著更高（87.9%对59.2%，p < 0.001）。对于其余错误，研究组之间未观察到显著差异。总体而言，3696个视频中有2861个（77.7%）被正确分类。实验组中正确分类视频的比例显著高于对照组（79.8%对75.6%，p = 0.003），表明干预具有统计学显著效果。
发现经过简短培训课程的评估人员在模拟心肺复苏视频中识别胸外按压深度过深的能力显著提高。
该试验在德国临床试验注册中心“BfArM - 德国临床研究注册中心（DRKS）”注册，注册号为DRKS00032661。
