Quality
The Oregon Clinic Gastroenterology has a comprehensive Quality Assurance program. We monitor quality indicators such as polyp detection rates, withdrawal times, and complications. We aim to meet and exceed national standards and provide excellent care.
The physicians at The Oregon Clinic Gastroenterology participate in GIQuIC, the GI Quality Improvement Consortium, a powerful tool in the fight against colon cancer. We look at different measures to ensure our procedures are as thorough and effective as possible. Click to read more on the GIQuIC website.
Below are three measures we track against the national goals that have been set by the GI societies.
Cecal Intubation Rate
The goal of a colonoscopy is to advance the scope all the way to the cecum and that is measured by Cecal Intubation Rate. The national standard has been set at 90% by the GI societies.
Average Withdrawal Time
Once the cecum is reached, the endoscopist will withdraw the scope while searching for adenomas. Adenomas are a type of polyp that can turn cancerous, so it’s important to identify and remove them during a colonoscopy. It has been determined that the withdrawal time should be no less than six minutes to ensure a thorough examination.
Adenoma Detection Rate
Adenoma Detection Rate, or ADR, is considered the most important quality indicator for a gastroenterologist. It calculates the percentage of time that at least one adenoma is detected during a colonoscopy. In fact, for every 1% increase in ADR, colorectal cancer rates decrease by 3% and morbidity decreases by 5%. The GI societies have set a national goal of 25% for Adenoma Detection Rate in screening colonoscopies.
The Oregon Clinic Gastroenterology - East's Liver Clinic has been recognized by the NCQA as a patient-centered specialty practice. Earning this recognition shows consumers that the practice has undergone a rigorous review of its capabilities and is committed to sharing information and coordinating care.
All of our Gastroenterology endoscopy centers have been accredited by the American Society for Gastrointestinal Endoscopy (ASGE) as a quality endoscopy center.
We are proud to be recognized by the Accreditation Association for Ambulatory Health Care. All of our sites have been awarded a three-year accreditation, the maximum given by AAAHC.
