Effectiveness of Vaginal Delivery Simulation in Novice Trainees

Area of Science:

• Medical Education
• Obstetrics and Gynecology
• Simulation Training

Background:

• Medical student confidence in vaginal deliveries increases with simulation, but skill performance impact is unclear.
• Assessing the effectiveness of simulation training in obstetrics and gynecology (OB/GYN) clerkships is crucial for skill development.

Purpose of the Study:

• To evaluate if integrating vaginal delivery simulation into the OB/GYN clerkship enhances third-year medical students' performance.
• To compare the skill performance of students receiving vaginal delivery simulation versus cervical exam simulation.

Main Methods:

• Third-year medical students were divided into two groups: vaginal delivery simulation (n=54) and cervical exam simulation (n=56).
• Performance was assessed via a simulated vaginal delivery, scored by blinded observers using a procedural checklist (0-30 scale).
• Statistical analysis included Mann-Whitney U and chi-square tests to compare scores and passing rates.

Main Results:

• Students who underwent vaginal delivery simulation achieved significantly higher mean scores (27 ± 3.2) compared to the control group (22 ± 3.5).
• A higher percentage of students in the simulation group (85%) passed the assessment compared to the control group (15%).
• No significant differences in performance were observed based on gender or the number of real-life deliveries performed.

Conclusions:

• A brief period of simulation training markedly improved end-of-rotation performance in vaginal delivery skills, despite equivalent clinical experience.
• Further simulation training, potentially over 5 hours, may be necessary for comprehensive preparation of residents and midwives.
• Simulation training is an effective tool for enhancing practical skills in medical education.
