In this issue of Endoscopy, Ravindran and colleagues from the TEAM-ENTS working group present a framework for core relevant non-technical skills (NTS) for endoscopy teams, derived from a two-phase qualitative mixed-method process involving the development of an NTS taxonomy for endoscopy teams, and refinement into a behavioral marker system (BMS) using Delphi methodology [1]. The authors' approach in this paper is robustbeginning with a systematic review, which included 14 team-based BMSs from other health disciplinesand has resulted in the creation of an endoscopy-specific team BMS that is applicable in numerous circumstances, ranging from generic everyday diagnostic endoscopy to emergency lifesaving procedures."The TEAM-ENTS BMS is an especially valuable resource in two areas: team-based endoscopy training and assessment of endoscopy teams."Medicine has drawn from other spheres, including business, sports, and other industries, in the preliminary development of schemata of highly effective healthcare teams [2]. One of the most referenced of these is crew resource management (CRM), a series of procedures from the aviation industry, which aims to ensure a high level of team performance, particularly in NTS, in a field where errors can lead to devastating adverse effects.In gastroenterology, we are perhaps more familiar with multidisciplinary teams in the delivery of care for patients with complex diseases, such as inflammatory bowel disease, cancer, or cirrhosis. However, endoscopy itself is performed by teams with varying roles, including endoscopists, nurses, trainees, technicians, allied healthcare staff, and other professionals. Furthermore pre-endoscopy care, such as bowel preparation and anticoagulation management, and post-endoscopy care are performed by teams that may either include members of the endoscopy team, work closely with the team, or be completely disparate from them. Endoscopy teams are often created ad hoc and may not be constructed with specific roles in advance. Team members may not have worked together, much Creating and improving highly effective endoscopic teams Referring to Ravindran S et al.
