The Kaiser Permanente Northern California Gastroenterology (GI) Fellowship program – which is based out of the San Francisco Medical Center – has been committed to advancing health care delivery through research and scholarship since its inception in 2019. Two fellows join our program each year, and they are required to pursue scholarly activities and complete a capstone research project before graduating. Despite being a young program, our GI fellows have been extremely productive academically, rivaling many of the established University-based GI fellowship programs across the United States.
In just four years, our GI fellows have published 34 manuscripts in high impact clinical journals (e.g., Gastroenterology, Clinical Gastroenterology and Hepatology, American Journal of Gastroenterology, Digestive Diseases and Sciences, and the New England Journal of Medicine) on topics such as COVID-19’s impact on colorectal cancer screening, risk of tumor seeding during colonoscopy, quantifying and forecasting the burden of eosinophilic esophagitis-related emergency department visits in the US, endoscopic management of achalasia and complex GI precancerous lesions, nutritional status and inflammatory bowel disease-related outcomes, colonoscopy quality, and reducing unnecessary surgeries for complex colorectal polyps. In addition, our GI fellows have presented their work in several national GI society conferences and received numerous accolades for their scholarship including the American College of Gastroenterology (ACG) Governor’s Award for Clinical Research, ACG Outstanding Poster Presentation Award, ACG Presidential Abstract Award, United European Gastroenterology Week’s Top Paper of the Year award, and KPSF’s Academy of Educators Quality Improvement Research Award.
Our GI fellowship program has been incredibly fortunate to attract these top-notch fellows who have elevated the academic status of our training program nationally. We are also extremely thankful for the entire village that supports these fellows including our KPSF Physician-and-Chiefs, GME leadership and staff, Division of Research’s biostatistical consulting unit, Drs. Aida Shirazi and Juleon Rabbani, and the fellowship’s program directors and faculty. It is truly remarkable how much these fellows have accomplished over the past four years, and we look forward to their continued success.
