Abstract

PURPOSE:

We previously found that a multifaceted outreach intervention achieved 82 % annual adherence to colorectal cancer (CRC) screeningwith fecal occult blood testing (FOBT). This study assessed adherence to FOBT after a second outreach.

METHODS:

We followed 225 patients in community health centers in Chicago, Illinois, who were randomized to the intervention group. Our primary analysis focused on 124 patients who completed FOBT during the first outreach and were due again for annual FOBT; 90% were Latino, 87% preferred to speak Spanish, and 77% were uninsured. Second outreach consisted of (1) a mailed reminder letter, a free fecal immunochemical test (FIT) with postage-paid return envelope, (2) automated phone and text messages, (3) automated reminders 2 weeks later if the FIT was not returned, and (4) a telephone call after 3 months. Our main outcome was completion of FIT within 6 months of the due date. We also analyzed the proportion of the original 225 patients who were fully screened for CRC over the 2-year study period.

RESULTS:

A total of 88.7% of patients completed a FIT within 6 months of their second outreach. Over the 2 years since the first outreach, 71.6% of the 225 patients assigned to the intervention group were fully up to date on CRC screening, another 11.1% had been screened suboptimally, and 17.3% were inadequately screened or not screened.
