Quality in pancreatic endoscopic ultrasound: what’s new in 2020?

Quality assessment and improvement of an endoscopic service has emerged as a basic component of everyday gastrointestinal endoscopy. In order to ensure a high level of quality, a series of actions must be adopted when performing an endoscopic examination. Nonetheless, quality still remains a qualitative parameter; thus, implementation of specific indicators of quality is warranted. Irrespective of the nature of the endoscopic procedure, quality indicators usually refer to either structural properties of an endoscopy unit (e.g., examination availability), procedural factors (e.g., diagnostic accuracy), or patient outcomes (e.g., occurrence of an adverse event related to performance of an endoscopic procedure). Moreover, they are usually classified into 3 distinct sections, according to the phase of the procedure they relate to: i.e., before, during, and after the examination. The aim of this review is to present measures that need to be adopted in order to reach an optimal quality level during an endoscopic ultrasound examination and to provide up-to-date data regarding the respective quality indicators implicated.
