Colorectal cancer screening saves lives, yet many people in primary care do not get screened on time. This randomized trial looked at ways to help overdue patients aged 50 to 74 years complete a fecal immunochemical test, or FIT. The study involved 5,244 patients who were past due for screening. Researchers wanted to know if specific reminders would help more people get tested within four months. The results show that simple communication methods can make a real difference for patients waiting for screening.
The researchers compared three different approaches against a standard control group. The control group received a regular envelope with no text messages and no reminder letter. One group received a health system-branded blue box. Another group received text message reminders. A third group received a reminder letter. The main goal was to see how many people completed the FIT within four months of being contacted.
The findings revealed clear differences between the methods. Patients who received text messages had a 21.2 percent completion rate compared to 14.6 percent for those who received no text reminders. This represents an increase of 6.6 percent. Patients who received a reminder letter had a 20.3 percent completion rate compared to 15.5 percent for those who received no letter. This represents an increase of 4.8 percent. Both of these increases were statistically significant. In contrast, the health system-branded blue box did not increase response rates. The completion rate for the blue box group was 17.8 percent, which was very close to the 18.0 percent rate of the standard envelope group. The difference was not statistically significant.
No safety concerns were reported in this study. There were no adverse events, serious adverse events, discontinuations, or tolerability issues to note. The interventions were simple communications that did not carry medical risks. Patients could feel safe using these reminder methods without worry about side effects or harm.
It is important to remember that this is a single randomized trial. While the results are positive for text messages and letters, one study cannot change all medical practice on its own. The study was conducted in a primary care setting with a specific group of patients. Other settings or patient populations might respond differently. The lack of effect from the branded box suggests that the physical appearance of the mail may not be as important as the message content. Patients should not assume that a fancy box will help them get screened if a simple letter or text works better.
For patients right now, this study suggests that asking for text reminders or letters from their doctor's office could help them get screened sooner. The evidence supports using these low-cost communication tools to improve screening rates. Patients who are overdue for screening should talk to their primary care team about setting up these reminders. Simple steps like this can help close the gap in screening and protect health.
