UNLABELLED
High-quality chest compressions are pivotal to improve survival from cardiac arrest. Basic life support training of school students is an international priority. The aim of this trial was to assess the effectiveness of a real-time training software (Laerdal QCPR®) compared to a standard instructor-based feedback for chest compressions acquisition in secondary school students. After an interactive frontal lesson about basic life support and high quality chest compressions, 144 students were randomized to two types of chest compressions training: 1) using Laerdal QCPR® (QCPR group- 72 students) for real-time feedback during chest compressions with the guide of an instructor who considered software data for students' correction 2) based on standard instructor-based feedback (SF group- 72 students). Both groups had a minimum of a 2-minute chest compressions training session. Students were required to reach a minimum technical skill level before the evaluation. We evaluated all students at 7 days from the training with a 2-minute chest compressions session. The primary outcome was the compression score, which is an overall measure of chest compressions quality calculated by the software expressed as percentage. 125 students were present at the evaluation session (60 from QCPR group and 65 from SF group). Students in QCPR group had a significantly higher compression score (median 90%, IQR 81.9-96.0) compared to SF group (median 67%, IQR 27.7-87.5), p = 0.0003. Students in QCPR group performed significantly higher percentage of fully released chest compressions (71% [IQR 24.5-99.0] vs 24% [IQR 2.5-88.2]; p = 0.005) and better chest compression rate (117.5/min [IQR 106-123.5] vs 125/min [115-135.2]; p = 0.001). In secondary school students, a training for chest compressions based on a real-time feedback software (Laerdal QCPR®) guided by an instructor is superior to instructor-based feedback training in terms of chest compression technical skill acquisition.

高质量胸外按压对于提高心脏骤停后的生存率至关重要。对在校学生进行基础生命支持培训是一项国际优先事项。本试验的目的是评估一款实时培训软件（Laerdal QCPR®）与标准的基于教员反馈的方法相比，在中学生获得胸外按压技能方面的有效性。在进行了一次关于基础生命支持和高质量胸外按压的互动式正面课程后，144名学生被随机分为两种胸外按压培训类型：1）使用Laerdal QCPR®（QCPR组 - 72名学生），在教员的指导下进行胸外按压时获得实时反馈，教员参考软件数据对学生进行纠正；2）基于标准的教员反馈（SF组 - 72名学生）。两组都至少有一次2分钟的胸外按压培训课程。在评估前，学生需达到最低技术技能水平。我们在培训7天后对所有学生进行了一次2分钟的胸外按压课程评估。主要结局是按压得分，这是软件计算得出的胸外按压质量的总体衡量指标，以百分比表示。125名学生参加了评估课程（QCPR组60名，SF组65名）。与SF组（中位数67%，四分位间距27.7 - 87.5）相比，QCPR组学生的按压得分显著更高（中位数90%，四分位间距81.9 - 96.0），p = 0.0003。QCPR组学生完全释放胸外按压的百分比显著更高（71% [四分位间距24.5 - 99.0] 对 24% [四分位间距2.5 - 88.2]；p = 0.005），胸外按压频率也更好（117.5次/分钟 [四分位间距106 - 123.5] 对125次/分钟 [115 - 135.2]；p = 0.001）。在中学生中，基于实时反馈软件（Laerdal QCPR®）并由教员指导的胸外按压培训在胸外按压技术技能获取方面优于基于教员反馈的培训。
