Evidence-Based
The Science Behind Colonoscopy Quality
Scopia is built on decades of research showing that measuring quality indicators and providing feedback directly improves patient outcomes.
Every 1% ADR Increase = 3% Fewer Interval Cancers
The landmark study by Corley et al. (2014), published in the New England Journal of Medicine, demonstrated that each 1% increase in adenoma detection rate is associated with a 3% decrease in the risk of interval colorectal cancer.
This means that improving detection quality during colonoscopy directly saves lives. Quality monitoring is not bureaucracy — it is a clinical intervention.

European Guidelines
ESGE Quality Indicators
The European Society of Gastrointestinal Endoscopy defines key performance indicators for colonoscopy quality. Scopia tracks all of them.
| Indicator | ESGE Minimum | ESGE Target | Scopia Users | Status |
|---|---|---|---|---|
| Adenoma Detection Rate (ADR) Percentage of colonoscopies in which at least one adenoma is detected | 25% | As high as possible | 0% | Exceeded |
| Caecal Intubation Rate (CIR) Percentage of colonoscopies reaching the caecum | 90% | ≥95% | 0% | Exceeded |
| Withdrawal Time (WT) Mean withdrawal time in negative screening colonoscopies | 6 min | ≥6 min | 0 min | Exceeded |
| Bowel Preparation Quality Adequate preparation rate | 90% | ≥90% | 0% | Exceeded |
Awareness
Most endoscopists don't know their own ADR. Without measurement, there's no basis for improvement.
Benchmarking
Seeing how you compare to peers creates natural motivation to improve — especially when the comparison is anonymous.
Continuous Improvement
Regular feedback creates a positive cycle: measure → feedback → adjust technique → measure again. Quality improves continuously.
Why Feedback Works
Audit and feedback is one of the most well-evidenced interventions for changing clinical practice. Studies consistently show that providing endoscopists with data about their performance leads to measurable improvement.
Scopia automates this process — every endoscopist receives personalised, timely feedback without any manual effort from leadership.
