Dr. David Ransohoff, professor of medicine at the University of North Carolina, Chapel Hill, will present “Making Guidelines for Colon Cancer Screening: Evidence, Policy and Politics” at the next Medicine: Mind the Gap Seminar on Tuesday, Sept. 27 from 11 a.m. to noon via NIH VideoCast, This seminar is the first of a three-part series on disease prevention screening. 

A major goal of clinical practice guidelines is to maximize benefit and minimize harm for patients. Yet many guidelines are made by many organizations and often they conflict on the same topic. As a result, Congress commissioned the Institute of Medicine to write a report about how to identify “guidelines you can trust.” This seminar will illustrate challenges and practical realities in guidelines-making by describing the evolution of evidence and of guidelines for colon cancer screening. 

As one of the first clinical epidemiologists trained at Yale University with Alvan Feinstein, Sr., Ransohoff has written extensively about how to improve research methods used to evaluate diagnostic tests, with seminal publications in major journals. Also trained in gastroenterology at the University of Chicago, he was one of the first clinical epidemiologists in a subspecialty field and has widely published on colon cancer screenings, including colonoscopies, fecal occult blood testing, sigmoidoscopies and virtual colonoscopies, as well as clinical practice guidelines and policy.  

Ransohoff will accept questions before and during his presentation via email at and on Twitter with #NIHMtG.
