Implementing the transvaginal ultrasound simulation training (TRUSST) programme for obstetric registrars.

Background: Transvaginal ultrasound (TVUS) training opportunities are limited due to its intimate nature; however, TVUS is an important component of early pregnancy assessment. Simulation can bridge this learning gap.
Aim: To describe and measure the effect of a transvaginal ultrasound simulation programme for obstetric registrars.
Materials and Methods: The transvaginal ultrasound simulation training (TRUSST) curriculum consisted of supported practice using virtual reality transvaginal simulators (ScanTrainer, Medaphor) and communication skills training to assist obstetric registrars in obtaining required competencies to accurately and holistically care for women with early pregnancy complications. Trainee experience of live transvaginal scanning was evaluated with a questionnaire. Programme evaluation was by pre-post self-reported confidence level and objective pre-post training assessment using Objective Structured Assessment of Ultrasound Skills (OSAUS) and modified Royal Australian and New Zealand College of Obstetrics and Gynaecology assessment scores. Quantitative data was compared using paired t tests.
Results: Fifteen obstetric registrars completed the programme. Numbers of performed live transvaginal ultrasound by trainees were low. Participants reported an increase in confidence level in performing a TVUS following training: mean pre score 1.6/5, mean post score 3/5. Objective assessments improved significantly across both OSAUS and RANZCOG scores following training; mean improvement scores 7.6 points (95% CI 6.2-8.9, p < 0.05) and 32.5 (95% CI 26.4-38.6, p < 0.05) respectively. It was noted that scores for a systematic approach and documentation were most improved: 1.9 (95% CI 1.4-2.5, p < 0.05) and 2.1 (95% CI 1.5-2.7, p < 0.05) respectively.
Conclusion: The implementation of a simulation-based training curriculum resulted in improved confidence and ability in TVUS scanning, especially with regard to a systematic approach and documentation.
