Adenoma Detection Rate

An adenoma is a benign (non-cancerous) tumor of glandular origin. Adenomas can grow from many organsincluding the colon. Although these growths are benign, over time they can potentially progress to become malignant (cancerous), at which point they are called adenocarcinomas. Even while benign, they have the potential to cause serious health complications by compressing other structures (mass effect) and by producing large amounts of unregulated hormones.

*Adenoma detection rate

The goals of screening colonoscopy are to prevent colorectal cancer by identifying and removing adenomas and to identify colon or rectal (referred to as colorectal) cancer if it is already present. The most important quality indicator, the Adenoma Detection Rate is the proportion of average-risk patients in whom a physician identifies adenomas during colonoscopy.

Complication Rate

Complication Rate is another indicator of quality care. The following chart shows the number of complications compared to the total number of colonoscopies performed:
