Eligibility criteria

	Include	Exclude	Rationale for exclusion
Population	Health care clinicians/practitioners- Nurses, Midwives, Doctors, Allied health workers, students from all health disciplines.	Sonographers Non-health professionals.	Sonographers and trainee sonographers possess more advanced imaging skills and are not within the scope of this review. Focus on training of populations with minimum basic healthcare training/experience/qualification. It is not advisable for non-healthcare professionals without training to perform PoCUS on patients/people.
Intervention/ Exposure	Antenatal Point-of-Care ultrasound (PoCUS) training including broader courses teaching scanning of multiple organ systems.	PoCUS training with no antenatal specific content (e.g., critical care- FAST, Abdominal, cardiac, lung, vascular). Advanced training (complex and interventional scanning) or full diagnostic ultrasound training leading to registration and qualification (sonographer training).	Non-antenatal PoCUS training is beyond the scope of this review. This review is focused on basic PoCUS training of health professionals. Advanced training such as those requiring lengthy courses, long-term supervision and formal accreditation/registration are beyond the scope of this review.
Outcome	Efficacy of training.Types of evidence/evaluation measures: Training course evaluation/Trainee satisfaction, testing of knowledge and practical skills (OSCE), Image quality review, diagnosis review, Confidence measures, Scanning frequency, Maternal/fetal outcomes.	Articles with limited description or reporting of the training intervention (training delivered), training assessment (evaluation measures) and outcome.	Inadequate methodological detail inhibits quality assessment and comparison between studies.
Study type	Original research. Studies involving antenatal PoCUS training evaluation- Cohort studies, cross-sectional studies, case control studies, observational studies, qualitative studies, case reports, clinical and randomized control trials. English language. Clinical/Human studies.	Review articles, Conference presentations/Abstracts, Letters, Editorials, Commentaries.Articles with Insufficient detail of described training interventions (training delivered), training assessment (evaluation measures) and outcome. Non-English articles. Animal studies.	Only original research articles were included for review. Conference presentations and abstracts (not full length articles) provide insufficient detail and peer-review scrutiny.
