Abstract

Background and Aims
Post-colonoscopy 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, we 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.

Methods
This multicentre, prospective, NED Automated Performance Reports to Improve Quality Outcomes Trial (NED-APRIQOT) randomised NHS endoscopy centres to intervention or control. Intervention-arm endoscopists were emailed tailored monthly reports automatically generated within NED, informed by qualitative interviews and behaviour change theory. The primary outcome was endoscopists’ aMNP during the 9-month intervention.

Results
From November 2020-July 2021, 541 endoscopists across 36 centres (19 intervention; 17 control) performed 54,770 procedures during the intervention, and 15,960 procedures during the 3-months post-intervention period. Comparing intervention-arm to control-arm endoscopists during the intervention period: aMNP was non-significantly higher (7%, 95% confidence interval (CI) -1% to 14%; p=0·08). Unadjusted MNP (10%, 95%CI 1-20%) and polyp detection rate (PDR) (10%, 95%CI 4-16%) were significantly higher. Differences were not maintained in the post-intervention period. In the intervention-arm, endoscopists accessing NED-APRIQOT webpages had higher aMNP than those who did not (118 vs 102 aMNP, p=0.03).

Conclusion
Although our automated feedback intervention did not increase aMNP significantly in the intervention period; MNP and PDR did significantly improve. Engaged endoscopists benefited most and improvements were not maintained post-intervention; future work should address engagement in feedback and consider the effectiveness of continuous feedback.
