Simulation-based Central Venous Catheter Insertion Training Increases Comfort Amongst Residents.

Abstract

Purpose: Central venous catheter (CVC) insertion is a fundamental skill required for trainees to become proficient. Simulation-based training (SBT) has been shown to improve trainees' CVC insertion performance effectively. However, implementing a CVC curriculum requires substantial costs and resources. Currently, there is a lack of validated CVC curricula that institutions can adopt as frameworks. This study aimed to evaluate the effectiveness of our institution's CVC simulation curriculum in improving residents' confidence and comfort with CVC insertion and management.

Materials and methods: First-year residents (n=118) participated in SBT between 2017 and 2023. Among them, 57 (48%) participants completed surveys before training and 6 months post-training to assess changes in comfort levels across various aspects of CVC insertion. Survey responses were analyzed to evaluate the overall changes in comfort by year and items.

Results: Overall comfort increased from 42.1% before training to 81.3% after training (P<0.01), with notable improvements in nonprocedural aspects. Comfort with performing the unsupervised procedure increased by 16.7% (P<0.05) but remained low post-training (29.6%).

Conclusion: These findings suggest that the curriculum effectively enhances residents' comfort, particularly in nonprocedural aspects, but only partially prepares them for unsupervised CVC insertions. This indicates a gap in procedural skill acquisition despite the overall positive trends. Implementing a similar CVC curriculum may help institutions reduce CVC insertion-associated complications.
