Background:

The long-axis in-plane approach for ultrasound-guided central venous catheterization is challenging due to the need for continuous needle visibility.
Existing training methods may not adequately address the complexities of this technique.

Purpose of the Study:

To evaluate the efficacy of a novel competency-based modular teaching system designed to improve skills in the long-axis in-plane approach for ultrasound-guided central venous catheterization.

Main Methods:

A simulator device with an ultrasound probe, simulated vessel, needle, and endoscope was used.
Participants underwent pre- and post-training assessments of success rate, needle tip visualization, and puncture accuracy.
A 2-hour hands-on training session with the developed system was provided.

Main Results:

The overall success rate for central venous catheterization significantly increased from 79% to 94% (P=.04).
Needle tip visualization was significantly improved (P=.02).
Puncture accuracy, specifically needle tip distance from the vessel center, significantly increased (P=.03).

Conclusions:

The developed competency-based modular teaching system effectively enhances needle tip visualization and puncture accuracy.
This novel system leads to a significantly higher success rate for ultrasound-guided central venous catheterization using the long-axis in-plane approach.
The step-by-step modular design facilitates skill acquisition for this challenging procedure.
