Inclusion criteria
Inclusion criteria: 1. Endoscopy units: NHS endoscopy units in the UK that perform at least 600 colonoscopies per annum 2. Endoscopists: All consenting independently-practising colonoscopists within a trial endoscopy unit 3. Colonoscopy data): All colonoscopy data from trust-employed independent endoscopists at participating endoscopy units
Exclusion criteria
Exclusion criteria: 1. Endoscopy units: 1.1. Independent sector and private sector endoscopy units 1.2. Endoscopy units performing fewer than 600 colonoscopies per annum 1.3. Endoscopy units without express support for the RCT from the endoscopy lead 1.4. Endoscopy units without express support for the RCT from the trust’s R&D team 1.5. Those units not participating in valid accurate data-uploading to NED 2. Endoscopists: 2.1. Non-consenting colonoscopists 2.2. Colonoscopists in non-independent (supervised) training (NB – trainees who are performing colonoscopies independently can participate) 3. Colonoscopy data: 3.1. Procedures performed by trainee endoscopists in non-independent (supervised) training 3.2. Procedures where an independent endoscopist was acting as a trainer 3.3. Procedures performed by endoscopists who are not employed by that trust 3.4. Procedures performed by endoscopists who are not anticipated to remain in the trust for the duration of the RCT
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Mean value of optimal detection KPI in the 2 study arms, measured at 12 months | — |
Secondary
| Measure | Time frame |
|---|---|
| Measured at 9 months in both arms: 1. Percentage of endoscopists above minimum standard for optimal detection KPI 2. Percentage of endoscopists above target standard for optimal detection KPI 3. mean value of optimal proximal detection KPI 4. Percentage of endoscopists above minimum standard for optimal proximal detection KPI 5. Percentage of endoscopists above target standard for optimal proximal detection KPI 6. Change over time in optimal detection KPI during the 9-month trial 7. Change over time in optimal proximal detection KPI during the 9-month trial 8. Subgroup analysis of endoscopists in the intervention group who access learning resource materials on the NED website during the trial 9. Subgroup analysis of endoscopists in the control group who access the basic NED website during the trial 10. Mean value in other colonoscopic KPIs (caecal intubation rate, terminal ileal intubation rate, rectal retroversion rate, colonoscopy withdrawal time, polyp retrieval success, patient comfort, bowel preparation quality) We shall also perform a nested study to correlate the opadKPI with both adenoma detection rate (ADR) and serrated polyp detection rate (SDR). This will be performed by asked each trial centre to review polyp histology from all independent colonoscopies within a specific 3-day period of the trial. We estimate that this will amount to 20-40 procedures per centre, totaling approximately 1500 procedures. | — |
