Kaiser Permanente Researcher Profiles


Theodore R. Levin, MD, is a Research Scientist at the Kaiser Permanente Northern California Division of Research; Chief of Gastroenterology at Kaiser Permanente Medical Center, Walnut Creek; and Assistant Clinical Professor of Medicine, University of California, San Francisco. He is the Clinical Lead for Colorectal Cancer Screening for The Permanente Medical Group. Dr. Levin's research interests include health services and outcomes research in gastroenterology. Particular areas of interest are colorectal cancer screening with colonoscopy fecal occult blood tests, and newer DNA-based technologies.

Current Position(s):

  • Research Scientist II, Division of Research, Kaiser Permanente Northern California
  • Chief of Gastroenterology, Kaiser Permanente Medical Center, Walnut Creek
  • Assistant Clinical Professor of Medicine, University of California, San Francisco

Section Affiliations:

Primary Research Interests:

  • Health services and outcomes research related to colorectal cancer screening in average risk populations and in patients with a positive family history of colorectal cancer
  • Outcomes research related to gastroesophageal reflux disease and dyspepsia

    Outreach for Colorectal Cancer Screening in African Americans Aged 45 to 49

    This study aims to 1) evaluate uptake of fecal immunochemical testing among African Americans aged 45 to 49 who receive outreach for such testing by mail, 2) examine the yield of screening results, including advanced adenomas and colon cancers, and 3) describe adverse events of screening among this population and compare them to those seen in people aged 50 to 55.
