Mo1708 ASSESSMENT OF QUALITY INDICATORS IN COLONOSCOPY TRAINING SERVICE IN BRAZI

Abstract

The aim of this study is to assess quality criteria in colonoscopy in the examinations of patients of the public health system, performed by the students of our unit. We retrospectively analyzed 1943 colonoscopies and its anatomopathological reports, performed from February 2018 to February 2019 by students of our endoscopy unit . Data were collected such as gender, age, body mass index, examination indication, family history, quality of preparation, withdraw time, polyp detection rate, adenoma detection rates, serrated polyp detection rates, and malignant neoplasms, as well as data on immediate complications. In the 1943 exams analyzed, we found that 1345 (69.22%) was female. The average age was 59 years. The main indication was prevention (36.64%). The caecum arrival rate was 98.9% in patients without obstructive lesions or inadequate preparation. The quality of the preparation was proper in 97% of the cases. The withdraw time was 10.54 minutes in examinations without procedures. Polyps resection rate was 40.92% and overall adenoma detection rate of adenomas was 30.83%. Nine malignant neoplasms were found (2.16%). Men had 1.3 times the prevalence of adenoma compared with women (P < 0.001: 95% CI: 1.1-1.5). Patients over 60 years old have 3.8 times the prevalence of adenomas than those under 40 years old (P < 0.001; 95% CI: 2.2-6.5). Patients aged 40 to 60 years have almost 3 times the prevalence of adenomas than patients under 40 years (P < 0.001; 95% CI: 1.6-5.0). There was 1 case of postpoiypectomy bleeding. The data obtained are compatible with the international quality criteria. The adenoma detection rate was higher in men. The detection of adenomas increased with age, highlighting the significant increase from 40 years. We emphasize the importance that colonoscopy training services measure their adenoma detection rates to achieve adequate levels of quality.
