GI endoscopy is increasingly the procedure of choice for the investigation and management of upper and lower GI symptoms. Internationally, key performance indicators (KPIs) are often used to provide key data points and auditable outcomes for endoscopists and endoscopy services with published standards existing for colonoscopy, bowel cancer screening, flexible sigmoidoscopy, ERCP and upper GI endoscopy. Quality assurance (QA) and training programs aim to ensure high skill levels of endoscopists and, supported by quality improvement programs (QI), aim to raise the quality of endoscopy service provision. There are currently few defined processes to guide services where standards are not being met. This document, written by a group of international endoscopy experts, is intended to provide pragmatic guidance to units or programs for managing performance that falls below the desired level. The guidance has been written generically with principals applicable to all endoscopic techniques.

胃肠道内窥镜检查越来越成为上，下胃肠道症状的调查和处理的首选程序。在国际上，关键绩效指标（KPI）经常用于为内窥镜医师和内窥镜检查服务提供关键数据点和可审核的结果，并采用已公布的结肠镜检查，肠癌筛查，柔性乙状结肠镜检查，ERCP和上消化道内窥镜检查标准。质量保证（QA）和培训计划旨在确保内镜医师的技能水平，并在质量改进计划（QI）的支持下，旨在提高内窥镜检查服务的质量。当前，很少有未定义的流程来指导未达到标准的服务。该文件由一组国际内窥镜专家撰写，旨在为单位或程序提供实用指导，以管理低于所需水平的性能。该指南的编写原则上适用于所有内窥镜技术。
