The Effects of Virtual Reality Ultrasound Training in Pairs Compared to Training Alone
Virtual Reality (VR) simulation has enabled high-quality, safe and efficient training of medical health care providers. However, training costs are considerable and may be optimized using interventions to improve learning. The aim of this study is to compare the effects of training in pairs versus training alone on an VR ultrasound simulator.
Methods: 30 medical students in their final year are randomized to either training in pairs or training alone. All participants are trained for two hours. Subsequently, all students are assessed on ultrasound performance on real patients in an ambulatory setting. Performance is assessed using a rating scale that has been validated in a previous study by two blinded assessors.
Other: Training in pairs (Dyad training)
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
- Performance test [ Time Frame: 6 hours ]The outcome measure was ultrasound examination skills on pelvic ultrasound examination of patients in an ambulatory setting. Participants were asked to perform a systematic ultrasonic transvaginal examination including measurement of endometrial thickness and estimate the volume of the right ovary. All patients were required to provide written consent to participate. A blinded OB/GYN consultant rated performance using a previously validated rating scale.Sample size calculation and statistical methods.
- Confidence [ Time Frame: 6 hours ]Students' confidence in managing the vaginal ultrasound examination are assessed after the post-intervention performance tests
