Case-mix-adjusted mean number of polyps per 100 procedures: a new candidate gold standard colonoscopy key performance indicator

Authors: Catlow, J, Lu, L, Sharp, L, Rutter, M, & NED APRIQOT Trialists Group

DOI: 10.1136/bmjgast-2025-001743

Journal: BMJ Open Gastroenterology

Year Published: 2025

Adenoma detection rate (ADR) has been criticised as a colonoscopy key performance indicator (KPI), for excluding serrated polyps, requiring histological data and fostering a ‘one-and-done’ attitude. Catlow et al. hypothesised that a case-mix-adjusted mean number of polyps (aMNP) would address these criticisms and provide a better measure of colonoscopy quality. Catlow et al. aimed to develop an aMNP using the National Endoscopy Database (NED) and assess its relationship with quality metrics.


Nationally Automated Colonoscopy Performance Feedback Increases Polyp Detection: The NED APRIQOT Randomized Controlled Trial

Authors: Catlow, J, Sharp, L, Wagnild, J, Lu, L, Bhardwaj-Gosling, R, Ogundimu, E, Kasim, A, Brookes, M, Lee, T, McCarthy, S, Gray, J, Sniehotta, F, Valori, R, Westwood, C, McNally, R, Ruwende, J, Sinclair, S, Deane, J, NED APRIQOT Trialists Group,& Rutter, M

Year Published: 2024

Postcolonoscopy colorectal cancer incidence and mortality rates are higher for endoscopists with low polyp detection rates. Using the UK’s National Endoscopy Database (NED), which automatically captures real-time data, Catlow et al. assessed if providing feedback of case-mix–adjusted mean number of polyps (aMNP), as a key performance indicator, improved endoscopists’ performance. Feedback was delivered via a theory-informed, evidence-based audit and feedback intervention.

Year Published: 2023

Significant morbidity and mortality can be associated with gastrostomy insertion, likely influenced by patient selection, indication and aftercare. Parr et al. aimed to establish what current variation in practice exists and how this has improved by comparison to their previously published British Society of Gastroenterology survey of 2010.


Impact of the National Endoscopy Database (NED) on colonoscopy withdrawal time: a tertiary centre experience

Authors: Shiha, M, Al-Rifaie, A & Thoufeeq, M

DOI: 10.1136/bmjgast-2021-000699

Journal: BMJ Open Gastroenterology

Year Published: 2021

Colonoscopy withdrawal time (CWT) is a key performance indicator affecting polyp detection rate (PDR) and adenoma detection rate (ADR). However, studies have shown wide variation in CWT and ADR between different endoscopists. The National Endoscopy Database (NED) was implemented to enable quality assurance in all endoscopy units across the UK and also to reduce variation in practice. Shiha, Al-Rifaie & Thoufeeq aimed to assess whether CWT changed since the introduction of NED and whether CWT affected PDR.
