Jason A. Dominitz MD, MHS

Jason Dominitz, MD, MHS is the National Program Director for Gastroenterology in the Veterans Health Administration. He is also the Gastroenterology Section Chief at the VA Puget Sound Health Care System and a Professor in the Department of Medicine at the University of Washington. Dr. Dominitz joined the VA Puget Sound in 1997 after completing his residency and gastroenterology fellowship at Duke University. He also was a fellow in Health Services Research at the Durham VA and received a Master’s Degree in clinical research from Duke concurrent with his gastroenterology fellowship. 

Dr. Dominitz has a longstanding interest in colorectal cancer screening and management. During his gastroenterology fellowship, he studied patient preferences for colorectal cancer screening tests and conducted a study of racial differences in colorectal cancer treatment. Since his arrival at the VA Puget Sound, he has collaborated with investigators at the University of Washington on several projects to study the quality of colonoscopy and of colorectal cancer treatment across the United States. Currently, he co-chairs a 16 year, randomized, prospective VA cooperative study comparing two leading strategies of colorectal cancer screening in 50,000 average risk Veterans (the CONFIRM Trial). This study, involving over 46 VA medical centers, is the first large-scale, prospective study in the United States comparing screening colonoscopy to a non-invasive, stool-based screening test. While colonoscopy is often regarded as the “best” test, recent research has raised questions about the effectiveness of colonoscopy in preventing colon cancer. Also, while colonoscopy is generally safe, there are known complications from this procedure that might limit its overall value as a screening tool. This study will determine if colonoscopy is truly more effective at preventing death from colorectal cancer than a simple, annual test of stool for evidence of bleeding. It will also assess the safety of colonoscopy and the impact of colonoscopy versus stool testing on the incidence of colorectal cancer.

Dr. Dominitz has served as the Gastroenterology Section Chief of the VA Puget Sound Health Care System since 2010 and as the National Program Director (NPD) for Gastroenterology since the inception of the National Gastroenterology Program in 2011. As the NPD, Dr. Dominitz has focused on assuring access for Veterans to high quality gastroenterology services. He is particularly interested in colonoscopy quality improvement and has led the development of new policies and tools related to this issue. Dr. Dominitz is the VA representative to the National Colorectal Cancer Round Table and is a member of the US Multi-Society Task Force on Colorectal Cancer. He is also a counselor on the Governing Board of the American Society for Gastrointestinal Endoscopy.
