Quality control of colonoscopy in daily practice -experience from Beskydy Gastrocentre

Abstract

Quality control of colonoscopy is indispensable for every endoscopy unit. The most important quality indicators include adenoma detection rate (ADR) or polyp detection rate (PDR), caecal intubation rate and procedure complications. The aim of our paper is to introduce the methodology and results of quality control in our endoscopy unit in 2012.

Methods: The data from all examinations are recorded in a database of colonoscopy in MS Excel. The main parts of the database comprise data about the endoscopist, epidemiologie data about the patient (sex, age, antiplateletand anticoagulation therapy, family history of colorectal cancer), data about the procedure (type, indication, sedation, bowel preparation, caecal intubation, ileal intubation, number of lesions, histology) and complications. A trained endoscopic nurse records histologie results separately. Quality parameters are evaluated every three months by a gastroenterologist and they are evaluated both for the endoscopy unit and for every endoscopist separately.

Results: From January to December 2012 194 sigmoideoscopies and 1,675 colonoscopies were performed, out of which 299 (18%) were screening colonoscopies. Intersubject variability of ADR forthe endoscopists involved was 40-65%.

Conclusions: Monitoring of basic quality parameters in the endoscopy unit including ADR is feasible. Intersubject variability of ADR among the endoscopists in our unit is relatively low.
