Summary
A new, low-cost central venous catheterization (CVC) simulation model was preferred by fellows and faculty over commercial trainers. This realistic and reusable model enhances understanding and ultrasound landmark identification for CVC placement training.
Area of Science:
- Medical Education
- Simulation Technology
- Pulmonary and Critical Care Medicine
Background:
- Central venous catheterization (CVC) is a core skill in pulmonary and critical care medicine (PCCM).
- Commercial CVC task trainers are effective but costly and logistically challenging for repeated practice.
- Access to effective CVC training tools is crucial for developing procedural competency.
Purpose of the Study:
- To assess learner and faculty perceptions of a novel, low-cost CVC simulation model.
- To compare the usability of the new model against a standard commercial CVC trainer.
- To provide a technical report on the construction of the developed CVC simulation model.
Main Methods:
- A prospective educational evaluation was conducted during a PCCM CVC workshop.
- Participants practiced CVC placement using both a standard commercial trainer and a newly developed simulation model.
- Faculty instructors evaluated both models for their instructional utility.
Main Results:
- All 15 fellows preferred the novel model, with 93% reporting improved understanding of CVC insertion steps.
- 73% of fellows found ultrasound landmark identification easier with the new model.
- Faculty instructors also preferred the novel model for teaching, citing its educational value and cost-effectiveness ($288.96 initial cost, reusable materials).
Conclusions:
- The developed CVC simulation model is a realistic, reusable, and cost-effective alternative to commercial simulators.
- The novel model demonstrates high learner and faculty preference and significant educational value.
- This task-aligned simulation model is suitable for integration into fellowship training programs, warranting further studies on skill acquisition and retention.
