To evaluate hand surgery fellow ultrasound (US) evaluations and performance of clinically relevant tasks after brief instruction.
Six hand surgery fellows completed an US assessment and a survey on US use before and 1 month after a 30-minute US course.
The time to obtain an adequate image decreased from 4 minutes 42 seconds (4:42; range, 3:57-7:55) to 0:52 (range, 0:30-1:14; P < .001). Participants' performance for structure identification improved from 9.7 (range, 8-13) to 12 (range, 10-13) of 14 structures (P < .05). The average time to completion decreased from 14:6 (range, 12:08-18:30) to 9:34 (range, 4:40-15:54; P < .01). After instruction, all 6 participants identified and measured the cross-sectional area of the median nerve, identified and measured a zone 3 flexor tendon gap, and identified a simulated flexor digitorum profundus avulsion and its level of retraction (P < .05). Five of 6 successfully administered an US-guided injection to the extensor carpi ulnaris subsheath.
After a 30-minute instructional session, hand surgery fellows can achieve a basic level of US competency.
评估手外科住院医师在接受简短指导后的超声（US）评估和执行临床相关任务的能力。
6 名手外科住院医师在接受 30 分钟 US 课程之前和之后 1 个月分别完成了 US 评估和 US 使用调查。
获得满意图像的时间从 4 分 42 秒（4:42；范围，3:57-7:55）减少至 0:52（范围，0:30-1:14；P<0.001）。参与者对结构识别的表现从 14 个结构中的 9.7（范围，8-13）提高到 12（范围，10-13）（P<0.05）。完成时间的平均值从 14:6（范围，12:08-18:30）减少至 9:34（范围，4:40-15:54；P<0.01）。在指导后，所有 6 名参与者都能识别和测量正中神经的横截面积、识别和测量 3 区屈肌腱间隙、识别模拟的指深屈肌腱断裂及其回缩水平（P<0.05）。6 名参与者中有 5 名成功地对手腕尺侧伸肌肌腱鞘进行了 US 引导下注射。
在手外科住院医师接受 30 分钟的指导课程后，他们可以达到基本的 US 能力水平。
