Adults at average risk for colorectal cancer can reduce the likelihood of receiving a diagnosis of late-stage disease by 70% by undergoing screening colonoscopy, according to the results of a case-control study published yesterday in Annals of Internal Medicine.
This decrease in risk was also seen for right colon cancer (OR=0.36; 95% CI, 0.16-0.80), where evidence of the effectiveness of colonoscopy has been limited.
A second study published in Annals found that patients who received electronic health record–linked automated reminders to undergo colorectal cancer screening were twice as likely to be up-to-date on screening as patients who were given usual care (56.8% vs 26.3%; P<.001). In this study, automated reminders included letters, pamphlets, and fecal occult blood tests mailed to participants.
Additional support—such as a follow-up phone call or nurse navigation—when added to automated reminders, increased the number of patients who were up-to-date on screening compared with automated methods alone.
