Radiologists are responsible for interpreting ultrasound (US) images accurately, troubleshooting, aiding sonographers, and advancing technology and research. Despite this, most radiology residents do not feel confident performing US independently. The purpose of this study is to evaluate the impact of an abdominal US scanning rotation and digital curriculum on radiology residents' confidence and skills in performing US.
All residents who were rotating in pediatric US at our institution for the first time were included (PGY 3-5). Those who agreed to participate were recruited sequentially from July 2018 to 2021 into (A) control and (B) intervention. B had a 1-week US scanning rotation and US digital course. Both groups completed a pre-and post-confidence self-assessment. Pre-and post-skills were objectively assessed by an expert technologist while participants scanned a volunteer. At completion, B completed an evaluation of the tutorial. Descriptive statistics summarized the demographics and closed questions. Pre-and post-test results were compared using paired-T tests, and effect size (ES) with Cohen's d. Open-ended questions were thematically analyzed.
PGY-3 and 4 residents participated, and were enrolled in A (N = 39) and B (N = 30). Scanning confidence significantly improved in both groups, with a greater ES in B (p < 0.01). Scanning skills significantly improved in B (p < 0.01) but not A. Eighty per cent of questionnaire responders used the integrative US tutorial and found it helpful. Free text responses were grouped into themes: 1) Technical issues, 2) Didn't complete course, 3) Didn't understand project, 4) Course was detailed and thorough.
Our scanning curriculum improved residents' confidence and skills in pediatric US and may encourage consistency in training, thus promoting stewardship of high-quality US.
放射科医生负责准确解读超声（US）图像、解决故障、协助超声医师，并推动技术和研究发展。尽管如此，大多数放射科住院医师仍对独立进行 US 检查缺乏信心。本研究旨在评估腹部 US 扫描轮转和数字课程对放射科住院医师进行 US 检查的信心和技能的影响。
本研究纳入了在我院首次轮转儿科 US 的所有住院医师（PGY3-5 级）。自 2018 年 7 月至 2021 年，同意参与的住院医师连续被招募至对照组（A）和干预组（B）。B 组进行了为期 1 周的 US 扫描轮转和 US 数字课程。两组均在入组前和出组后完成了信心自我评估。参与者对一名志愿者进行 US 扫描时，由一位专家技术员对其进行客观的技能评估。B 组在课程结束时完成了对教程的评价。描述性统计总结了人口统计学和封闭问题的结果。采用配对 T 检验比较入组前后的结果，采用 Cohen's d 计算效应量（ES）。对开放性问题进行主题分析。
PGY3 和 4 级住院医师参与了研究，其中 39 人被纳入 A 组，30 人被纳入 B 组。两组的扫描信心均显著提高，B 组的 ES 更大（p < 0.01）。B 组的扫描技能显著提高（p < 0.01），但 A 组没有。80%的问卷应答者使用了综合 US 教程，认为其很有帮助。自由文本回复被分为以下主题：1）技术问题，2）未完成课程，3）不理解项目，4）课程详细全面。
我们的扫描课程提高了住院医师在儿科 US 方面的信心和技能，可能会鼓励培训的一致性，从而促进高质量 US 的管理。
