Supplementary Material for: Quality Assurance in Endoscopy: Which Parameters?

<b><i>Background:</i></b> The verbalisation of quality standards and parameters by medical societies are relevant for qualitative improvement but may also be an instrument to demand more resources for health care or be a unique characteristic. Within the health care system 3 different quality levels can be defined: structure, process and result quality. <b><i>Methods:</i></b> The current S2k guideline of the German Society for Gastroenterology (quality requirements for gastrointestinal endoscopy) AWMF registry no. 021-022 provides recommendations based on the available evidence for the structure quality (requirements for equipment, human resources) as well as for the process quality (patient preparation, conduct, documentation) and result quality (follow-up of specific endoscopic procedures). <b><i>Results:</i></b> Based on these recommendations, measurable quality indicators/parameters for the endoscopy have been selected and formulated. General quality parameters for endoscopic examinations are given as well as quality parameters for specific procedures for the preparation, conduct, and follow-up of specific endoscopic interventions. <b><i>Conclusion:</i></b> Only the regular review of processes and courses by means of defined measurement parameters builds up the basis for corrections based on facts. In addition, the implementation of recommended standards may be an instrument in demanding more resources from the health care system and, therefore, should be embedded as routine.
