A central venous catheter (CVC) is an important medical tool used in critical care and emergent situations. Integral to proper care in many circumstances, insertion of a CVC introduces the risk of central line-associated blood stream infections and mechanical adverse events; proper training is important for safe CVC insertion. Cognitive task analysis (CTA) methods have been successfully implemented in the medical field to improve the training of postgraduate medical trainees, but can be very time-consuming to complete and require a significant time commitment from many subject matter experts (SMEs). Many medical procedures such as CVC insertion are linear processes with well-documented procedural steps. These linear procedures may not require a traditional CTA to gather the information necessary to create a training curriculum. Accordingly, a novel, streamlined CTA method designed primarily to collect cognitive cues for linear procedures was developed to be used by medical professionals with minimal CTA training. This new CTA methodology required fewer trained personnel, fewer interview sessions, and less time commitment from SMEs than a traditional CTA. Based on this study, a streamlined CTA methodology can be used to efficiently gather cognitive information on linear medical procedures for the creation of resident training curricula and procedural skills assessments.
中心静脉导管（CVC）是重症监护和紧急情况下使用的重要医疗工具。在许多情况下，CVC 的插入是适当护理的关键，但它会增加与中心静脉导管相关的血流感染和机械不良事件的风险；因此，安全插入 CVC 需要进行适当的培训。认知任务分析（CTA）方法已成功应用于医学领域，以提高研究生医学生的培训水平，但完成这些方法非常耗时，并且需要许多主题专家（SME）投入大量时间。许多医疗程序，如 CVC 插入，都是线性过程，具有记录良好的程序步骤。这些线性过程可能不需要传统的 CTA 来收集创建培训课程所需的信息。因此，开发了一种新颖的简化 CTA 方法，主要用于收集线性程序的认知线索，以便接受过最少 CTA 培训的医疗专业人员使用。与传统 CTA 相比，这种新的 CTA 方法需要更少的训练有素的人员、更少的访谈会议和 SME 较少的时间投入。基于这项研究，简化的 CTA 方法可用于高效收集有关线性医疗程序的认知信息，以创建住院医师培训课程和程序技能评估。
