About this trial
Prospective observational cohort study on the learning curve for the sonographic assessment of labor progress (fetal head position and station) amongst obstetric caregivers.
Study participants: convenience sample of 20 obstetric caregivers working in the department of obstetrics and gynecology at the University Hospital of Leuven - recruited over a 12-month period.
Format of the training program:
1. Observational phase: the goal is to measure the accuracy of the clinical assessment of fetal head position and station throughout the different stages of labor by caregivers working within the department. 2. Self-study: reading of the 2018 practice guidelines on intra-partum ultrasound by ISUOG and watching the corresponding teaching video. 3. Supervised implementation phase: one-to-one teaching by experienced sonographers, who initially demonstrate, later interactively supervise the quality of the scans acquired by the obstetric caregiver. 4. Proficiency testing: from this point onwards, the trainee independently performs ultrasound scans in labor to asses fetal head position and station. The scans will be repeated by the expert sonographer, the results will be compared (qualitatively and quantitatively) and immediate feedback provided if indicated. Every observation will have a binary outcome (success or failure of trainee acquisition) according to predefined quality assessment criteria. Observations will be continued until proficiency is reached (saturation of the learning curve).

Trial outcomes
Primary outcomes
Proficiency for the sonographic assessment of fetal head station during labor.
Number of ultrasound examinations a caregiver needs to perform under expert supervision to obtain proficiency - defined as the CUSUM (Cumulative Sum analysis) performance graph dropping below two consecutive boundary lines.

Secondary outcomes
Knowledge, attitude and practices regarding intrapartum ultrasound use.
Changes in KAP (Knowledge, Attitude and Practice) survey scores throughout the completion of the training program. Higher scores indicate better knowledge or a more favorable opinion regarding intrapartum ultrasound use (attitude, practice) - lower scores the opposite. * Knowledge survey: 5 questions on the sonographic assessment of fetal head station (score ranging from 0-5/5), 5 questions on the sonographic assessment of fetal head position (score ranging from 0-5/5). * Attitude: 6 questions, score ranging from 0-6/6. * Practice: 6 questions, score ranging from 0-6/6. * One Likert scale on confidence level regarding sonographic assessment of fetal head station (score ranging 0-5/5, 0 indicating "not confident at all", 5/5 "very confident") * One Likert scale on confidence level regarding sonographic assessment of fetal head position (score ranging 0-5/5, 0 indicating "not confident at all", 5/5 "very confident")
