Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Detection of growth restricted fetuses relies primarily on abdominal ultrasound examinations during pregnancy. Many clinicians, however, have not received systematic training and may therefore perform inadequately. We wish to examine, whether systematic, simulation-based training can improve diagnostic accuracy of estimated fetal weight by ultrasound at different levels of clinical experience.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants are physicians working at obstetric departments. Participant characteristics (age, experience in years and number of monthly scans) are recorded. Participants perform two abdominal growth scans prior to randomization and estimated fetal weight is compared to birth weight. Mean absolute percentage error is calculated as a measure of diagnostic accuracy.

Participants are then randomized to either control (no intervention) or intervention. The latter group receives training on the Metaphor Scantrainer trans abdominal ultrasound simulator until they pass a previously validated test. After completing the training the participants use a mannikin to practice systematic approach and 'knobology'.

All participants then perform another two growth scans. Diagnostic accuracy before and after the intervention or control period is compared.

We wish to examine the effect of systematic training on the diagnostic accuracy of estimated fetal weight by ultrasound across different levels of clinical experience.

If an effect can be found in the inexperienced participants, simulation-based training in obstetric ultrasound could be implemented as a part of basic obstetric training and/or as a means of maintaining skills.
