Details and patient eligibility

About

In a prospective, randomized Trial, the investigators compare Hands-on teaching and frontal teaching using a Training Video for learning how to perform an assisted delivery by vacuum extraction on a pelvic Training model. Objective Structured Assessment of Technical Skills (OSATS) scores are the primary outcome. The investigators hypothesize that Hands-on Training is superior to a video-teaching with regard to the OSATS scores achieved by the Trainees.

Full description

The optimal mode of Training surgical novices how to perform an assisted delivery by means of vacuum extraction is unknown. We prospectively randomize probands to a 30 min hands-on (group 1) and a 30 min demonstration (group 2) training session teaching a standardized vacuum Extraction (VE) algorithm scheme on a pelvic training model. Probands are tested with a 24 item Objective Structured Assessment of Technical Skills (OSATS) scoring system after training and 48 hours, and 72 hours thereafter. OSATS scores are the primary outcome. Performance time (PT), self assessment (SA), confidence (CON), and global rating scale (GRS) are the secondary outcomes. Statistics will beperformed using Mann-Whitney U-test, chi-square test, and multivariable logistic regression analysis.

137 participants in 2 patient groups

hands-on Teaching

Experimental group

Description:

Medical students receive a 30 minutes hands-on training session. All study probands perform assisted delivery (operative vaginal delivery) by vacuum extraction on a pelvic model immediately after the training.

Treatment:

Other: hands-on teaching

Frontal teaching

Active Comparator group

Description:

Medical students receive a 30 minutes frontal teaching session using a training video demonstrating how to perform assisted delivery (operative vaginal delivery) by vacuum extraction on a pelvic model immediately after the training.
