What is your Adenoma Detection Rate?

This is the main question to ask a gastroenterologist when you are considering a colonoscopy. The British Society of Gastroenterology (BSG), have developed quality assurance measures and key performance indicators for the delivery of colonoscopies within the UK.

The Adenoma Detection Rate (ADR) is the national BSG benchmark for measuring high quality colonoscopy procedures.

An ADR is a direct measure of the effectiveness of the colonoscopy that a gastroenterologist offers. So always pick a colonoscopy doctor with a high adenoma detection rate. This will mean they are locating and removing precancerous colon polyps from a higher percentage of patients.

Look for a GI specialist with a colonoscopy Adenoma Detection Rate of at least 15% in women and 25% in men.

Adenoma Detection Rates at OneWelbeck Digestive Health:

  • The BSG aspirational ADR rate is 20%. All our specialist endoscopists have upper quintile ADR (33.51-52.51%) of the BSG aspirational target, with an average performance of around 30%
  • This high ADR rate reduces the risk of a missed diagnosis or the need for a more invasive or expensive treatment

How much time do you normally take to do a colonoscopy?

As part of a colonoscopy procedure, a gastroenterologist will insert the colonoscope device into your colon (bowel) until it stops near the appendix and then carefully inspect the colon for precancerous polyps while withdrawing the colonoscope to look at the lining of your large bowel. This is called the withdrawal time.

The longer your doctor spends examining each segment of your colon, the more likely they are to find a precancerous polyp or lesion. Longer withdrawal times during screening colonoscopies are associated with increased adenoma detection rates.

So, when you are looking for a qualified gastroenterologist for a colonoscopy, ask for their withdrawal time because this will be one of the best ways to compare gastroenterologists.

How many colonoscopies do you perform each year?

The BSG aspirational target is 150 colonoscopies per year. Many of our gastrointestinal consultants carry out over 1,000 a year between their NHS and private practice services.

Leading the way in bowel cancer prevention

At OneWelbeck, we have brought together an outstanding clinical team and excellent patient experience, creating an ideal environment for a bowel screening programme.

Our endoscopists each take great pride in their individual colonoscopy performance and are leading the way in bowel cancer prevention by exceeding the BSG colonoscopy aspirational targets.

As a company, Welbeck Health will openly register our colonoscopy outcomes in UK and international databases to continue preventing potential bowel cancer and gastrointestinal problems.
