EP27.13: The significance of proposed method of parsing complex cardiac fetal anomalies on prenatal diagnostic accuracy

Abstract

Electronic poster abstractsintrusive investigation than transabdominal (TA) and as such the use of real patients for training or skill assessment in this modality has ethical considerations. The objective of this study was to assess the quality of images obtained by novice trainees on a TV ultrasound simulator with inbuilt metrics following a simulation teaching session. Methods: 32 trainees with minimal ultrasound experience completed a two-hour gynecology ultrasound simulation session on the Volutracer OPUS system (Medge Platforms) using a TV probe. The trainees were asked to obtain 12 different views of pelvic structures and complete a pre-test, online tutorial and finally a post-test. The outcomes measures were: average accuracy score for obtaining the correct anatomical plane, percentage of correctly acquired target planes, average number of movements, time to achieve image, distance travelled by probe and accumulated angling of the probe for each image. An unpaired T test assuming equal variance pre-and post-test aggregate scores was performed. Results: Mean post-test vs. pre-test aggregate scores were accuracy score: 5.27 vs. 3.95 (p = <0.0001) percentage of correctly acquired target planes: 43% vs. 28% (p = 0.0001), reduction in number of movements: 12 vs. 23 (p = <0.0001), user time: 14.3 seconds vs. 21.6 seconds (p = 0.001), distance 14.98 vs. 24.89 (p = 0.006) and in accumulated angling: 205 vs. 316 (p = 0.053). Conclusions: There was an improvement in all outcome measures following the simulation training session. If further investigation demonstrates that the simulation metrics are able to determine differing levels of clinical competence, then simulation in TV ultrasound could provide a valuable adjunct to scanning on real patients for both training and assessment.
