Adding extra simulation training after achieving mastery did not improve ultrasound-guided peripheral intravenous (USGPIV) catheter placement skills in medical students. Further practice beyond initial mastery did not enhance skill transfer to real-world procedures.
Area of Science:
- Medical Education
- Simulation Training
- Ultrasound-Guided Procedures
Background:
- Simulation-based mastery learning (SBML) enhances skill transfer.
- Limited data exist on the benefits of additional training after achieving mastery.
- This study investigates if extra SBML improves ultrasound-guided peripheral intravenous (USGPIV) catheter placement skill transfer.
Purpose of the Study:
- To determine if additional mastery-level simulated performances improve skill transfer for USGPIV catheter placement.
- To evaluate the impact of extra practice on procedural success and checklist performance.
- To assess skill retention after 6 months.
Main Methods:
- 48 medical students underwent SBML for USGPIV placement to a mastery standard.
- Participants were assigned to 0, 4, or 8 additional mastery-level simulated sessions.
- Skill transfer was assessed on human volunteers, with a retention phase after 6 months.
Main Results:
- No significant improvement in USGPIV placement success or checklist performance with additional training sessions.
- Success and checklist performance were comparable across all training groups.
- Retention rates after 6 months were higher for groups with 4 or 8 additional sessions compared to the control group.
Conclusions:
- In novices, additional mastery-level simulated USGPIV practice did not improve immediate skill transfer.
- Skill retention after 6 months showed promise with additional practice sessions.
- Further research may be needed to optimize SBML protocols for complex procedures.
