The use of client reminders to increase screening for breast and cervical cancers is recommended on the basis of strong evidence of effectiveness. The use of client reminders to increase colorectal cancer screening with fecal occult blood testing also is recommended based on strong evidence of effectiveness. Evidence is insufficient, however, to determine effectiveness of client reminders in increasing colorectal cancer screening with other tests (colonoscopy, flexible sigmoidoscopy), because of inconsistent evidence. Client reminders are written (letter, postcard, email) or telephone messages (including automated messages) advising people that they are due for screening. Client reminders may be enhanced by 1 or more of the following: follow-up printed or telephone reminders; additional text or discussion with information about indications for, benefits of, and ways to overcome barriers to screening; and assistance in scheduling appointments. These interventions can be untailored to address the overall target population or tailored with the intent to reach one specific person, based on characteristics unique to that person, related to the outcome of interest, and derived from an individual assessment.
