The quality of the visual information transmitted from a scene is crucial for effective medical supervision in prehospital settings. This study investigated the influence of wearable camera mount locations on visibility during simulated out-of-hospital cardiopulmonary resuscitation. A prospective, observational, non-randomized simulation study was conducted to replicate a cardiac arrest scenario adhering to an advanced life support (ALS) protocol. Seven advanced emergency medical technicians (AEMTs) participated, and 5 camera mount locations were tested: the sternum, forehead, lateral side of the eyelid, mid-nasal, and glabella. Video recordings were captured from the Airway, Intravenous (IV), and Leading providers. Five experienced medical directors independently evaluated visibility scores (1-5) for each procedure with optimal visibility defined as a score of 4 to 5. Glabella mount demonstrated the highest median visibility score and interquartile range (5 [4-5]) and proportion of optimal visibility (77.5%) for most procedures across provider positions. Mixed models revealed significant estimates for the lateral side of the eyelid, mid-nasal, and glabella mounts compared to the sternum, with glabella having the largest effect size (estimate = 1.62). Generalized linear mixed models showed that the glabella mount had the highest odds ratio (OR = 8.07, 95% confidence interval [CI]: 3.01-21.6) to achieve optimal visibility. Wearable camera mount location significantly affected visibility during simulated resuscitation. Mounting cameras closer to eye level provided the most accurate visual data. Further research using objective measures, such as artificial intelligence, and evaluating the visibility of wearable cameras in real-world situations is warranted to optimize simulation-based training for prehospital care.
从场景传输的视觉信息质量对于院前环境中的有效医疗监督至关重要。本研究调查了可穿戴式摄像头安装位置对模拟院外心肺复苏期间可见性的影响。进行了一项前瞻性、观察性、非随机模拟研究，以复制遵循高级生命支持（ALS）方案的心脏骤停场景。七名高级急救医疗技术人员（AEMT）参与其中，测试了5个摄像头安装位置：胸骨、前额、眼睑外侧、鼻中部和眉间。从气道、静脉输液（IV）和主导提供者处捕获视频记录。五名经验丰富的医疗主任独立评估每个程序的可见性评分（1-5），最佳可见性定义为4至5分。眉间安装在大多数程序中，跨提供者位置显示出最高的中位数可见性评分和四分位间距（5 [4-5]）以及最佳可见性比例（77.5%）。混合模型显示，与胸骨相比，眼睑外侧、鼻中部和眉间安装有显著估计值，眉间的效应量最大（估计值 = 1.62）。广义线性混合模型表明，眉间安装实现最佳可见性的优势比最高（OR = 8.07，95%置信区间[CI]：3.01-21.6）。可穿戴式摄像头安装位置在模拟复苏期间显著影响可见性。将摄像头安装在更接近眼睛水平的位置可提供最准确的视觉数据。有必要使用人工智能等客观测量方法进行进一步研究，并评估可穿戴式摄像头在现实世界中的可见性，以优化基于模拟的院前护理培训。
