Umbilical catheterization training: Tissue hybrid versus synthetic trainer

Area of Science:

• Medical Simulation
• Pediatric Training
• Neonatal Procedures

Background:

• Umbilical catheterization is a common neonatal procedure.
• Deliberate practice training is crucial for developing proficiency.
• Comparing simulation modalities is essential for optimizing training.

Purpose of the Study:

• To compare skill and knowledge outcomes of umbilical catheterization training.
• To evaluate two simulation methods: a tissue-hybrid simulator (REAL) and a synthetic trainer (ART).

Main Methods:

• Prospective randomized control study design.
• Pediatric residents randomized to REAL or ART training.
• Pre-post-training skill and knowledge assessments.
• Neonatologist comparison of simulator fidelity.

Main Results:

• Significant post-training skill improvement in both groups (P < 0.001 for REAL, P < 0.0001 for ART).
• No significant differences in post-training skill, knowledge, or self-efficacy between REAL and ART.
• Higher fidelity for REAL compared to ART (P < 0.01).

Conclusions:

• Both REAL and ART simulators effectively improve resident skills and knowledge.
• REAL offers superior face validity, but resident outcomes are comparable.
• Further research on patient outcomes is needed to fully evaluate simulator impact.
