Randomised comparison of theoretical versus hands-on training of vaginal operative delivery by vacuum extraction using Objective Structured Assessment of Technical Skills (OSATS)

Objective: To compare vaginal operative delivery by vacuum extraction (VE) after hands-on training vs. expert video demonstration. Material and Methods: We randomized medical students to a 30 min expert demonstration (group one) or a 30 min hands-on (group two) training using a standardized VE algorithm on a pelvic training model. Students were tested with a 40 item Objective Structured Assessment of Technical Skills (OSATS) scoring system after training and four days later. OSATS scores were the primary outcome. Performance time (PT), self assessment (SA), confidence (CON), and global rating scale (GRS) were se…
