Sustained effect of simulation-based ultrasound training on clinical performance: a randomized trial

Area of Science:

• Medical Education
• Obstetrics and Gynecology
• Medical Simulation

Background:

• Transvaginal sonography (TVS) is a crucial skill for Ob-Gyn residents.
• Traditional clinical training may not adequately prepare residents for independent TVS performance.
• Objective assessment of early-stage resident competency in TVS is essential.

Purpose of the Study:

• To compare the effectiveness of simulation-based TVS training versus clinical training alone.
• To evaluate the impact of initial training modality on Ob-Gyn residents' clinical performance.
• To assess skill retention 2 months into residency.

Main Methods:

• A randomized controlled trial involving 33 Ob-Gyn residents with no prior ultrasound experience.
• Intervention group received virtual-reality TVS simulation until expert level, followed by mannequin training.
• Control group received clinical training only. Clinical performance was assessed using the Objective Structured Assessment of Ultrasound Skills (OSAUS) scale after 2 months.

Main Results:

• The simulation-based training group (n=18) demonstrated significantly higher OSAUS scores (59.1%) compared to the control group (n=15) (37.6%) (P < 0.001).
• A higher pass rate (85.7%) was observed in the intervention group versus the control group (8.3%) (P < 0.001).
• Scan completion numbers were similar between groups during the 2-month clinical training period.

Conclusions:

• Initial simulation-based TVS training significantly enhances Ob-Gyn residents' clinical performance.
• The benefits of simulation-based training are sustained after 2 months of clinical practice.
• Simulation offers a valuable adjunct to traditional clinical training for developing early ultrasound proficiency.
