Background: Ultrasound has emerged as an important diagnostic tool in the management of multiple obstetric pathologies. However, the poor skills of trainee doctors in the application of ultrasound can significantly impact clinical outcomes. To overcome these challenges, simulation-based training can bridge the gap in skills and enhance the quality of patient care.
Materials and methods: The ultrasound simulation training curriculum involved virtual-reality simulator training to assist residents in acquiring competencies for accurate and holistic care of pregnant patients and complicated pregnancies. After hands-on training on the simulator, evaluation was done using pre- and post-tests based on the Objective Structured Assessment of Ultrasound Skills (OSAUS) scale and image-based questionnaire. Quantitative data was compared using paired t-tests.
Result: A total 28 resident doctors completed the study. Participants reported an increase in mean response score to the image-based questionnaire following the training, with a mean pre-score of 9.86/15 and mean post-score of 11.43/15 with a mean improvement score 1.57 points (95%CI 1.64-1.5, p < 0.05). Objective assessments improved significantly across OSAUS scores following training, with 14.79/25 (SD 2.79) Pre-training and 19.36 (SD 3.03) post-training mean improvement score 4.57 points (95% CI 3.91-5.23, p < 0.05). It was noted that scores for systematic approach and documentation were most improved.
Conclusion: This study highlights the effectiveness of a simulation-based training curriculum in improving the ability of residents in scanning, especially with regard to a systematic approach and documentation of ultrasound scans. The use of virtual reality ultrasound simulator training can be an effective way to bridge the learning gap in ultrasound scanning.
