摘要
Teaching ultrasound (US) has not been sufficiently standardised yet. Most educational devices in US consist of 2-dimensional B-mode images. However, the identification of anatomic structures in the 3-dimensional space can only be learned by practical hands-on education. In US simulators, US images of real pathologies are created by the examination of a dummy with a mock transducer. The resulting US images were previously recorded in a 3-dimensional format and were processed in a way which facilitates the reconstruction and projection of the images on a screen corresponding to the sectional plane of the mock transducer, simulating the conventional B-mode images. This enables standardised, real-time, hands-on training of US pathology detection. In June 2007, a hands-on workshop on US simulators was performed in the 1st Department of Internal Medicine of the Johannes Gutenberg-University in Mainz/Germany. During 15 days, 209 participants from all parts of Germany were trained. The workshop included an evaluation to elucidate the value and acceptance of this kind of US training. 149 evaluation forms could be analysed (72%). The participants were fairly heterogeneous and belonged to the following subspecialties: internal medicine (50%), surgery (11%), others (18%). 72% were residents, 22% consultants. 40% of the participants worked in university hospitals, 12% in hospitals of highest clinical level, and 42% in hospital of basic care. Baseline knowledge in US was quite different, too, reflected in the number of independently performed US examinations prior to this course: 0-400 examinations (44%), 401-1000 examinations (14%), 1001-4000 examinations (7%), and >4000 examinations (2%). Of note, 56% of the participants had not received any kind of formal training in US. In daily practice 77% were trained by tutors, whose formal qualification in US was unknown. Only a small proportion of the tutors had received training in US according to the standards of the German Association of US in Medicine (DEGUM). This evaluation shows the high level of acceptance of simulator-based training in US despite the heterogeneity of the participants. 95% rated the teaching value as "high" and 95% wished an integration of US simulators in training curricula. In summary, this analysis proves the need for standardised training programmes in US teaching in Germany and a high level of acceptance of simulator-based US training.
