详细说明
21 private practice gastroenterologist endoscopists from Berlin performed a prospective quality assessment study including at least 10.000 screening colonoscopies. After informed consent, patients data are included (age, sex, family history, colonoscopy performance parameters and findings, therapy performed, histology of biopsies and/or polypectomies, complications (immediate and late) and patient acceptance. The latter was retrieved by patient questionnaires returned after a minimum of 2 weeks. Data were centrally collected in an anonymized way
Primary outcome parameter:
- Correlation of adenoma detection rate with case volume and other confounding factors (e.g., withdrawal time)
Secondary outcome parameters:
- Complications and method of assessment (immediate recording versus later questionnaire enquiry)
- Quality of bowel preparation in relation to outcome Patient acceptance in relation to procedural factors (e.g., sedation)
- Quality of pathology reports and histologic outcome of polypectomy
Later follow-up (after 5-10 years) of the preventive effect of colonoscopy is planned and has been part of the protocol and patient consent form.
