Stool testing is currently the preferred method of screening for colorectal cancer (CRC), due to the relatively low risk (1). Currently, two main fecal tests are considered: the guaiac fecal occult blood test (gFOBT) and the fecal immunochemical test (FIT). Majority of the evidence states that FIT has superior performance characteristics compared to the gFOBT. Additionally, research suggests that gFOBT is used within hospital acute care settings as a diagnostic test, despite the lack of evidence supporting the use of stool-based tests outside of CRC screening (2-4). The objective of this research project was to determine the current practices within Newfoundland and Labrador regarding CRC screening and to determine under what context gFOBT and FIT are being used. An online survey was distributed to physicians in NL who are members of the Newfoundland and Labrador Medical Association (NLMA). Due to poor response rate, preliminary rudimentary statistical data analysis was completed on the responses. The conclusions are made based on limited responses. All of the family and internal medicine physicians recommend CRC screening within their practice. Additionally, the primary method of CRC screening, unanimously, was FIT and that a majority of the responders agree to discontinue gFOBT. The results showed that stool tests are currently being ordered for reasons other than CRC screening such as GI bleeding, anemia and iron deficiency investigations. The survey responses suggested that the stool testing protocols were being followed appropriately, although there is room for improvement.
