Target Audience

Healthcare providers. 


  1. List the screening options and guidelines for colorectal cancer screening.
  2. Discuss the advantages and challenges to different population-based approaches to colorectal cancer screening.
  3. Reflect upon patient perspectives on barriers and facilitators to colorectal cancer screening.

Dr. Charlton's presentation will include the following 3 phases on the colorectal cancer screening projects she conducted in the VA. The following research questions will be addressed.

  • Phase I: Does a home fecal immunochemical test (FIT) kit mailed to veterans accompanied by educational materials result in improved CRC screening rates in an average risk, asymptomatic population with no recent record of CRC testing compared to a group receiving education materials only and a group receiving usual care (no intervention)?  
  • Phase II: Does adding introductory telephone calls plus reminders improve CRC screening rates beyond a FIT mail-only intervention?
  • Phase III: What proportion of patients previously screened with FIT would be willing to undergo a second round of FIT screening 1 year after completing their initial FIT?
