Pilot study. Two pilot studies were conducted to determine which modules to include in the training curriculum and how to provide a standardized instruction of trainees. The first pilot study included 10 OB/GYN residents and 10 OB/GYN consultants, who rated and commented each module with regards to how useful they were to pelvic ultrasound training. These ratings were used to develop a training curriculum consisting of a series of basic gynecologic training modules. The second pilot study included 6 medical students, of which half trained in pairs and the other half trained alone with clinician instructions. This enabled the research team to develop a template for the instruction that should be provided by clinician instructors in the group of participants that practiced alone.
