BACKGROUND
Clinicians are increasingly using point-of-care ultrasonography for bedside examinations of patients. However, proper training is needed in this technique, and it is unknown whether the skills learned from focused Ultrasonography courses are being transferred to diagnostic performance on patients.
METHODS
Thirty-one physicians were randomized to participate in a focused Ultrasonography course or control circumstances before they examined 4 patients with different abdominal conditions by ultrasonography. Performance scores and diagnostic accuracy were compared using independent samples t test and binary logistic regression, respectively.
RESULTS
There was a significant difference in the performance score between the intervention group (27.4%) and the control group (18.0%, P = .004) and the diagnostic accuracy between the intervention group (65%) and the control group (39%, P = .014).
CONCLUSIONS
Clinicians could successfully transfer learning from an Ultrasonography course to improve diagnostic performance on patients. However, our results also indicate a need for more training when new technologies such as point-of-care ultrasonography are introduced.
背景
临床医生越来越多地使用即时超声检查对患者进行床边检查。然而，这项技术需要适当的培训，并且从聚焦超声课程中学到的技能是否能转化为对患者的诊断表现尚不清楚。
方法
31名医生在通过超声检查4例患有不同腹部疾病的患者之前，被随机分配参加聚焦超声课程或处于对照环境。分别使用独立样本t检验和二元逻辑回归比较表现得分和诊断准确性。
结果
干预组（27.4%）和对照组（18.0%，P = .004）之间的表现得分存在显著差异，干预组（65%）和对照组（39%，P = .014）之间的诊断准确性也存在显著差异。
结论
临床医生可以成功地将超声课程中学到的知识转化为提高对患者的诊断表现。然而，我们的结果也表明，当引入即时超声等新技术时，需要更多的培训。
