Colorectal cancer (CRC) is the second leading cause of cancer deaths in the United States. Furthermore, it is preventable with routine screening that reduces the incidence of and mortality from CRC.
Nearly all authoritative groups endorse CRC screening, yet more than 40% of the population remains unscreened.1 Although much effort has been invested in trying to improve rates of CRC screening, the overall effect of individual strategies at the patient, physician, or system level has been relatively modest to date. In particular, web-based approaches have been viewed as having tremendous promise for increasing participation, but to date there has been little supporting evidence.
