UrduCRC is known as the “most preventable yet least prevented” form of cancer.[1],[2] As the second leading cause of cancer death in the United States, CRC remains a significant public health challenge. Just this year, more than 150,000 patients will be diagnosed and treated, and 50,000 patients will die from colorectal cancer.[3] It is estimated 64 percent of these deaths could be prevented through early detection and screening.[4]
This latest set of guidelines, published online and in the September print issues of The American Journal of Gastroenterology (AJG) and GIE Gastrointestinal Endoscopy, emphasize the importance of determining and measuring priority quality indicators. While quality measurements related to all indicators may not always be feasible, given time, cost, and staffing constraints, a set of extremely important measures called priority indicators have been developed to guide practices in where to focus. Based on clinical relevance, evidence of variable performance, and feasibility of measurement, the priority indicators for colonoscopy outlined are:
- Adenoma detection rate (ADR), or how often the endoscopist finds an adenoma, which is a precancerous growth in the colon
- Sessile serrated lesion detection rate, or how often the endoscopist finds a sessile serrated lesion, which is another precancerous growth in the colon
- Rate of using recommended screening and surveillance intervals
- Bowel preparation adequacy rate
- Cecal intubation rate, or what proportion of the time the endoscopist is able to view the entire colon
“ADR plays a critical role in evaluating the performance of the colonoscopists,” said Douglas K. Rex, MD, MACG, MASGE, the lead author. “It is recommended that ADR calculations include screening, surveillance, and diagnostic colonoscopy but exclude indications of a positive noncolonoscopy screening test and therapeutic procedures for resection or treatment of known neoplasia, genetic cancer syndromes, and inflammatory bowel disease.”
Co-author Nicholas J. Shaheen, MD, MPH, MACG, MASGE, added, “Endoscopy teams now have an updated set of guidelines which can be used to enhance the quality of their colonoscopies, and should certainly use these current quality measures to ‘raise the bar’ on behalf of their patients.” He added, “Understanding deficiencies in performance is only possible through quality measurement, and this has an important impact on critical outcomes including cancer development. One way endoscopy units can do so is to participate in GIQuIC.”
GIQuIC (GI Quality Improvement Consortium, Inc.) is a medical specialty registry designed by gastroenterologists for gastroenterologists to collect, organize, and display digestive healthcare data for multiple purposes, such as research, quality improvement initiatives, and providing quality measure data to CMS’ Merit-based Incentive Payment System (MIPS). ACG and ASGE are collaborators in GIQuIC.

About the ASGE/ACG GI Colonoscopy Quality Indicators
As a product of the ASGE/ACG Task Force on Quality in Endoscopy, this document was reviewed and approved by the governing boards of the American Society for Gastrointestinal Endoscopy and the American College of Gastroenterology. The present update integrates new data pertaining to previously proposed quality indicators. Gastroenterologists should review this updated guidance with their healthcare teams and create a plan for evolving their quality improvement programs to align with priority indicators set forth in the document.
About the ASGE/ACG Task Force on Quality in Endoscopy
In the early 2000s, physician leaders in gastroenterology started a movement to define aspects of quality for endoscopy. As leaders in promoting excellence in gastrointestinal endoscopy, ASGE and ACG formed a Task Force, comprised of nationally recognized endoscopic experts, to identify objective measures that could be used to define high-quality endoscopic services for the diagnosis and treatment of diseases and conditions of the digestive tract. Published in April 2006 and updated in 2015, the ACG-ASGE Gastrointestinal Endoscopic Quality Indicators established the foundation for assessing prevailing patterns of care against best practices, revolutionizing the area of quality in endoscopy. These indicators have guided measure development for use not only in continuous quality improvement activities, but for inclusion in government reporting programs such as the Medicare Quality Payment Program (QPP) and its Merit-based Incentive Payment System (MIPS).
About Gastrointestinal Endoscopy
Gastrointestinal endoscopic procedures allow the gastroenterologist to visually inspect the upper gastrointestinal tract (esophagus, stomach and duodenum) and the lower bowel (colon and rectum) through an endoscope, a thin, flexible device with a lighted end and a powerful lens system. Endoscopy has been a major advance in the treatment of gastrointestinal diseases. For example, the use of endoscopes allows the detection of ulcers, cancers, polyps and sites of internal bleeding. Through endoscopy, tissue samples (biopsies) may be obtained, areas of blockage can be opened, and active bleeding can be stopped. Polyps in the colon can be removed, which has been shown to prevent colon cancer.
About the American College of Gastroenterology
Founded in 1932, the American College of Gastroenterology (ACG) is an organization with an international membership of more than 20,000 individuals from 86 countries. The College’s vision is to be the preeminent professional organization that champions the prevention, diagnosis, and treatment of digestive disorders, serving as a beacon to guide the delivery of the highest quality, compassionate, and evidence-based patient care. The mission of the College is to enhance the ability of our members to provide world class care to patients with digestive disorders and advance the profession through excellence and innovation based upon the pillars of Patient Care, Education, Scientific Investigation, Advocacy and Practice Management. www.gi.org
About the American Society for Gastrointestinal Endoscopy
