Ultrasound in primary care: Consensus recommendations on its applications and training. Results of a 3-round Delphi study

BACKGROUND: The introduction of portable and pocket ultrasound scanners has potentiated the use of ultrasound in primary care, whose many applications have been studied, analyzed and collected in the literature. However, its use is heterogeneous in Europe and there is a lack of guidelines on the necessary training and skills. OBJECTIVES: To identify the fundamental applications and indications of ultrasound for family physicians, the necessary knowledge and skills, and the definition of a framework of academic and pragmatic training for the development of these competencies. METHODS: A modified 3-round Delphi study was carried out in Catalonia, with the participation of 65 family physicians experts in ultrasound. The study was carried out over six months (from September 2020 to February 2021). The indications of ultrasound for family physicians were agreed (the > = 75th percentile was considered) and prioritised, as was the necessary training plan. RESULTS: The ultrasound applications in primary care were classified into seven main categories. For each application, the main indications (according to reason for consultation) in primary care were specified. A progressive training plan was developed, characterised by five levels of competence: A (principles of ultrasound and management of ultrasound scanners); B (basic normal ultrasound anatomy); C (advanced normal ultrasound anatomy); D (pathologic ultrasound, description of pathological images and diagnostic orientation); E (practical skills under conditions of routine clinical practice). CONCLUSION: Training family physicians in ultrasound may consider seven main applications and indications. The proposed training plan establishes five different levels of competencies until skill in real clinical practice is achieved.
