Objective:
Currently, there are no established guidelines for obstetric ultrasound training at the core medical student clerkship level. Our objective was to develop practical, consensus-based learning objectives in second- and third-trimester ultrasound and assess the feasibility of implementing these objectives into a clinical curriculum.
Study Design:
Using the modified Delphi approach, a panel of expert stakeholders (n = 23) was assembled to reach consensus on the proposed learning objectives. A model curriculum was created consisting of a video tutorial, in-person training, and an optional tracker and piloted at two academic medical centers. Participant perception of acquired ultrasound skills and the program were assessed using a modified, previously validated survey. Pre- and postprogram survey responses were compared using the Chi-squared test of association. A p-value of <0.05 was considered statistically significant.
Results:
The expert panel reached consensus on five learning objectives to include determination of fetal number and presentation, assessment of fetal heart rate, determination of placental location, assessment of amniotic fluid volume, and a general understanding of the biophysical profile and its indications. A total of 26 students participated in the piloted curriculum. On completion, a majority of participants reported improved confidence in understanding and performing prenatal ultrasound in the second and third trimesters (p < 0.05). The majority of participants valued a hands-on ultrasound curriculum.
Conclusion:
We propose practical, consensus-based learning objectives for second- and third-trimester sonography during the core clerkship with demonstrated feasibility in a two-center pilot program.
Key Points:
· Ultrasound is a valuable skill for medical students.. · Specific learning objectives in obstetric ultrasound are currently lacking.. · We propose consensus-based objectives and a model curriculum.. · A two-center pilot study demonstrated efficacy..

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
