A core curriculum for basic EUS skills: An international consensus using the Delphi methodology

BACKGROUND AND OBJECTIVES: During recent years, the demand for EUS has increased. However, standardized training programs and assessments of clinical quality measures are lacking. We therefore aimed to establish a basic curriculum for EUS fellows that includes a prioritized list of interpretational capabilities and technical skills. MATERIALS AND METHODS: International key-opinion leaders were invited to participate in a Delphi process. An electronic three-round iterative survey was performed to attain consensus on skills that 70% of the participants found either very important or essential for a newly graduated endosonographer. RESULTS: Of 125 invited experts, 77 participated in the survey. Initially, 1,088 skills were suggested, resulting in a core curriculum containing 29 interpretational skills and 12 technical skills. The top-five interpretation skills included abilities to discern between normal anatomy and pathology, to identify the entire pancreas and ampullary region, to identify solid versus fluid-filled structures, to detect bile duct and gallstones, and to identify a pancreatic mass of 5 mm or larger. For technical skills, ability to insert the endoscope from the mouth to the second part of duodenum, to obtain FNA adequately and safely, to navigate the scope tip to follow anatomical landmark structures, to achieve endoscopic position of each of the four stations, and to perform passage of the scope past a hiatal hernia were given the highest ranking. CONCLUSIONS: After a structured Delphi process involving 77 international experts, a consensus was reached for a basic curriculum for EUS fellows to be included during training.
