超声成像设备在临床和教学环境中越来越受欢迎，但没有关于其在医学教育中使用的系统信息。我们对手持超声（HHU）设备在本科医学教育中的作用、意义和局限性进行了系统评价。我们使用以下策略检索了科克伦、PubMed、Embase和Medline：[（手持式或便携式或袖珍或“床旁系统”）和超声]和（教育或培训或本科或“医学生”或“医学院”）。我们保留了12篇关于本科医学教育的文章。我们总结了HHU的使用模式、合并和估计HHU检测左心室功能不全的敏感性和特异性。报告的特征是异质的：培训时间（1-25小时），参与的学生人数（1-整个队列），扫描的受试者人数（27-211）和学习类型（自我指导与传统讲座+动手课程）。大多数研究报告了心脏HHU检查，但检查了其他解剖区域，例如腹部和甲状腺。合并敏感性0.88 [95%可信区间（CI）0.83-0.92]和特异性0.86（95% CI 0.81-0.90）高的检测左心室收缩功能障碍的学生。医学教育中关于HHU设备的数据很少且不完整，但经过培训的学生可以达到较高的诊断准确性，尽管在有限数量的（主要是心脏）病理中。目前还没有达成共识的协议最适合医学生的教育需求，也没有长期影响的数据，在熟练程度的衰减或在这种情况下部署HHU的财务影响。
Ultrasound imaging devices are becoming popular in clinical and teaching settings, but there is no systematic information on their use in medical education. We conducted a systematic review of hand-held ultrasound (HHU) devices in undergraduate medical education to delineate their role, significance, and limitations. We searched Cochrane, PubMed, Embase, and Medline using the strategy: [(Hand-held OR Portable OR Pocket OR “Point of Care Systems”) AND Ultrasound] AND (Education OR Training OR Undergraduate OR “Medical Students” OR “Medical School”). We retained 12 articles focusing on undergraduate medical education. We summarised the patterns of HHU use, pooled and estimated sensitivity, and specificity of HHU for detection of left ventricular dysfunction. Features reported were heterogeneous: training time (1–25 hours), number of students involved (1-an entire cohort), number of subjects scanned (27–211), and type of learning (self-directed vs. traditional lectures + hands-on sessions). Most studies reported cardiac HHU examinations, but other anatomical areas were examined, e.g. abdomen and thyroid. Pooled sensitivity 0.88 [95% confidence interval (CI) 0.83–0.92] and specificity 0.86 (95% CI 0.81–0.90) were high for the detection of left ventricular systolic dysfunction by students. Data on HHU devices in medical education are scarce and incomplete, but following training students can achieve high diagnostic accuracy, albeit in a limited number of (mainly cardiac) pathologies. There is no consensus on protocols best-suited to the educational needs of medical students, nor data on long-term impact, decay in proficiency or on the financial implications of deploying HHU in this setting.
