adenoma detection rate
Also written as: ADR
Quality metric measuring the percentage of average-risk screening colonoscopies that detect at least one adenomatous polyp.
Full Definition
The adenoma detection rate is a key quality indicator for colonoscopy screening programs, calculated as the percentage of screening examinations in average-risk patients aged 50 and older that identify one or more adenomatous polyps. ADR serves as a surrogate marker for colonoscopy effectiveness and is associated with reduced risk of interval colorectal cancers. Professional societies establish minimum ADR benchmarks (typically 25% for men, 15% for women) to ensure adequate screening quality and patient safety.
Usage
Usage note: May be abbreviated as ADR in technical reports; specify patient demographics when reporting rates.
