Accreditation of digestive endoscopy services: a method of quality assuring?

Accreditation is one method of assuring quality, but the evidence base in support of service accreditation is mixed. More recent experiences indicate that accreditation may accelerate improvements. Our aim is focused on endoscopy service accreditation and we conducted a literature search using Medline (via Pubmed) and the Cochrane Center Register of Controlled Trials up to January 2020. Worldwide numerous centers fail to meet important quality indicators as suggested by international guidelines. Accreditation can provide means for detecting many problems and correcting them by implementing agreed standards.
