Evaluating the effects of comprehensive simulation on central venous catheterization training: a comparative...

Area of Science:

• Medical Education
• Surgical Simulation
• Medical Device Technology

Background:

• Ultrasound-guided central venous catheterization (US-IJCVC) requires physician experience to minimize complications.
• Current simulation-based training (SBT) often covers only needle insertion, limiting comprehensive skill development.
• The Dynamic Haptic Robotic Trainer (DHRT) and its extended version, DHRT+, offer advanced training solutions.

Purpose of the Study:

• To evaluate the impact of the DHRT+ on resident self-efficacy and skill acquisition in US-IJCVC.
• To compare the effectiveness of comprehensive training (DHRT and DHRT+) versus standard training (DHRT alone).

Main Methods:

• 47 residents trained on DHRT; 59 residents trained on DHRT and DHRT+.
• Central line self-efficacy (CLSE) surveys administered pre- and post-training.
• Post-simulation manikin-based US-IJCVC assessed by expert raters using a standardized checklist.

Main Results:

• The DHRT+ group demonstrated significantly better performance in "verbalizing consent" and "aspirating blood through the catheter".
• Both groups showed improved self-efficacy, but comprehensive training predicted higher self-efficacy in "equipment use" and "catheter securing".
• DHRT+ training enhanced specific procedural skills and overall self-efficacy in central line placement.

Conclusions:

• Integrating comprehensive training modules, like the DHRT+, significantly enhances US-IJCVC education.
• Advanced simulation tools improve both learning gains and self-efficacy in medical residents.
• Comprehensive SBT is a valuable approach for improving complex procedural training.
