With advancements in technology and push for health care reform and reduced costs, minimally invasive procedures, such as those that are ultrasound-guided, have become an essential part of radiology, and are used in many divisions of radiology. By incorporating standardized training methodologies in a risk free environment through utilization of a simulation center with phantom training, we hope to improve proficiency and confidence in procedural performance.
Twenty-nine radiology residents from four levels of training were enrolled in this prospective study. The residents were given written, video, and live interactive training on the basics of ultrasound-guided procedures in our simulation center on a phantom mannequin. All of the teaching materials were created by residents and staff radiologists at the institution.
Residents demonstrated statistically significant improvement (P < .05) between their pre- and posttest scores on both the written and practical examinations. They also showed a trend toward improved dexterity in the technical aspects of ultrasound-guided procedures (P = .07) after training. On the survey questionnaire, residents confirm improved knowledge level, technical ability, and confidence levels pertaining to ultrasound-guided procedures.
The use of controlled simulation based training can be an invaluable tool to improve the knowledge level, dexterity, and confidence of residents performing ultrasound-guided procedures. Additionally, a simulation model allows standardization of education.
随着技术的进步以及医疗改革和降低成本的推动，微创程序（如超声引导程序）已成为放射学的重要组成部分，并广泛应用于放射学的多个领域。通过在模拟中心利用模拟训练来实施标准化的培训方法，我们希望提高程序操作的熟练度和信心。
本前瞻性研究纳入了来自四个培训级别的 29 名放射科住院医师。住院医师在我们的模拟中心的模拟人体模型上接受了关于超声引导程序基础知识的书面、视频和现场互动培训。所有教学材料均由机构内的住院医师和放射科工作人员创建。
在书面和实践考试中，住院医师的预测试和后测试分数均显示出统计学上的显著改善（P <.05）。在培训后，他们在超声引导程序的技术方面的灵巧度也表现出改善的趋势（P =.07）。在问卷调查中，住院医师证实他们的超声引导程序的知识水平、技术能力和信心水平均有所提高。
基于受控模拟的培训可以成为提高执行超声引导程序的住院医师的知识水平、灵巧度和信心的宝贵工具。此外，模拟模型还可以实现教育的标准化。
