USE OF HIGH-DEFINITION EQUIPMENT IMPROVES POLYP DETECTION RATE: OBSERVATIONS FROM THE EUROPEAN COLONOSCOPY QUALITY INVESTIGATION (ECQI) QUESTIONNAIRE
Publication History
Publication Date:

Aims:
To assess the influence of the use of high-definition (HD) equipment on polyp detection rate (PDR) using questionnaire responses from across Europe.
Methods:
The development of the procedure questionnaire, by the European Colonoscopy Quality Investigation (ECQI) Group, has been previously described in posters presented at UEGW, 2015 and 2016. Data collection is an ongoing process: we analysed data collected between 2/6/16 and 30/4/18. The ESGE definition of PDR was used: all screening and diagnostic colonoscopies in patients aged ≥50 years were identified in our dataset. A polyp was considered detected if there was a positive answer to 'Polyp detected' in any colon segment, or a polypectomy was reported under 'Endoscopic intervention'.
A univariate binary logistic regression model was used to determine the effect of use of HD equipment on PDR.
Results:
3335 of 6445 procedures met the criteria for PDR analysis, 2975 of which provided information upon their use (or not) of HD equipment. PDR was higher in procedures where HD equipment was used: 44.2% (957/2166) vs. 30.9% (250/809); odds ratio 1.77, 95% CI 1.49, 2.10, p < 0.001. Of the 2157 providing information on the type of HD equipment used, the majority, 1804 (83.6%) used both HD scope and monitor/screen, while 256 (11.9%) reported using scope only and 97 (4.5%) monitor/screen only: the effect on PDR approached significance (p = 0.054, see table).

Conclusions:
The use of HD equipment is associated with an improved PDR. The reported use of HD scope alone appears to produce a worse PDR than HD monitor/screen either with or without HD scope.
