目的
2
基于Miller金字塔模型构建“知识整合—操作强化—临床协同”三维一体教学模式,通过小样本随机对照试验初步探索其在介入超声住院医师规范化培训学员临床胜任力培养中的效果。
方法
2
选取三峡大学第一临床医学院2023至2024级40名超声影像专业住院医师规范化培训学员作为研究对象,所有学员先接受3个月传统带教(理论授课+临床跟台),结束后采用客观结构化临床考试(objective structured clinical examination, OSCE)进行首次考核(含5个标准化考站,Cronbach’s
α
=0.89)。随后在确保性别、学历、入科成绩及首次OSCE成绩基线均衡的前提下,采用分层区组随机化法将学员分为对照组(
n
=20,继续传统带教)与试验组(
n
=20,实施三维一体教学干预),干预包括知识整合(每周1次多学科融合课程)、操作强化(每周2次手术模拟穿刺训练和并发症处理应急演练)和临床协同(每周1例PBL-CBL联合案例教学)。干预3个月后进行第2次OSCE考核,比较组间得分及提升幅度差异,并采用Likert 5级量表调查教学满意度。

Objective
2
To preliminarily evaluate the effectiveness of a Miller's pyramid-based three-dimensional integrated teaching model (knowledge integration
skill reinforcement
and clinical collaboration) for clinical competence enhancement in standardized training of interventional ultrasound residents through a randomized control trial with a small sample size.
Methods
2
We enrolled 40 ultrasound residents undergoing standardized training in the 2023 and 2024 cohorts from The First Clinical Medical College of China Three Gorges University. All the participants received three months of traditional teaching (theoretical lectures + clinical observation)
followed by an initial assessment using an objective structured clinical examination (OSCE) consisting of five standard stations (Cronbach's
α
=0.89). Subsequently
ensuring baseline equivalence in sex
education level
entry scores
and initial OSCE scores
the participants were divided by stratified block randomization into control group (
n
=20) to continue to receive traditional teaching and experimental group (
n
=20) to receive the triad instruction that comprised knowledge integration (multidisciplinary courses once a week)
skill reinforcement (punctur
e simulation and complication management/ emergency response training twice a week)
and clinical collaboration (PBL-CBL case studies once a week). A second OSCE was administered after three months of intervention. OSCE scores and score improvements were compared between the two groups. Teaching satisfaction was surveyed using a 5-point Likert scale.
Results
2
The two groups showed no significant difference in the initial OSCE score [(60.60±4.50) vs. (60.20±3.33)
P
=0.751
]
or other baseline indicators (sex
education level
and entry score). The experimental group exhibited a significantly higher post-intervention OSCE score [(84.20±2.80) vs. (73.65±2.82)
P
<
0.001
]
and a significantly greater improvement in the overall score [(23.60±4.35) vs. (13.45±3.02)
P
<
0.001

compared with the control group. Specifically
