Podcast # 327: No More Hemoccults

Author: Don Stader, MD

Educational Pearls:

  • The use of fecal occult blood tests is falling out of favor in emergency departments
  • These tests have strong evidence suggesting their efficacy in colon cancer screening but clinical significance in ED is limited
  • They have relatively high false positive and false negative rates
  • Small/microscopic bleeding are often not clinically significant in the ED but can lead to increased costs from over-testing and other harms from fecal occult blood testing
