This study will test the effectiveness of mailing fecal immunochemical tests (FITs) in increasing colorectal cancer (CRC) screening rates in U.S. adults ages 45-75. We are implementing this study in two age groups, 45-49 years and 50-75 years.
Trial (Age Group 50-75) This randomized controlled trial assesses the effectiveness, feasibility, acceptability, and cost-effectiveness of mailing FITs from a central location to patients served by FQHCs. Subjects are randomly selected and assigned to receive either a mailed FIT intervention (Arm 1: Trial Mailed FIT Intervention - Age Group 50-75) or usual care (Arm 2: Trial Usual Care - Age Group 50-75). To assess United States Preventive Services Task Force recommendations for annual screening, we will mail subjects one round of FIT per year for up to two years. Sub-study (Age Group 45-49) A sub-study assesses the effectiveness of mailing FITs from a central location to patients who are 45-49 years of age and newly eligible for CRC screening. The sub-study also assesses the impact of varying the appearance of the FIT packet mailing envelope on FIT return. All eligible patients from one FQHC clinic site are randomly assigned to receive either a mailed FIT intervention that includes an enhanced mailing envelope (Arm 3: Sub-study Mailed FIT Intervention Enhanced Envelope - Age Group 45-49) or a plain envelope (Arm 4: Sub-study Mailed FIT Active Comparator Plain Envelope - Age Group 45-49). The Trial (Age Group 50-75) and the Sub-study (Age Group 45-49) also assess the effectiveness of delivering patient navigation from a central location to facilitate follow up colonoscopy for patients with a positive (abnormal) FIT result.

Subjects are mailed an introductory letter advising them that they will receive a FIT kit in the mail. Next, subjects are mailed a FIT packet in an envelope that contains a cover letter, CRC information sheet, FIT instruction sheet, and FIT kit with a pre-paid return envelope. Subjects receive up to two mailed letters reminding them to complete and return the FIT. Subjects receive FIT results via letter or phone call.
Subjects are mailed an introductory letter advising them that they will receive a FIT kit in the mail. Next, subjects are mailed a FIT packet in an enhanced envelope that contains a cover letter, CRC information sheet, FIT instruction sheet, and FIT kit with a pre-paid return envelope. The enhanced envelope is a yellow padded envelope with a USPS tracking label and sticker message: "Important information from your doctor". Subjects receive up to two mailed letters reminding them to complete and return the FIT. Subjects receive FIT results via letter or phone call.

Proportion of Subjects Who Completed Colorectal Cancer (CRC) Screening Within 6 Months (Trial - Age Group 50-75)
"The proportion of subjects who received study Intervention (Age Group 50-75) and did not receive study intervention (Usual Care - Age Group 50-75 who completed CRC screening using any of the screening modalities recommended by the United States Preventive Services Task Force per electronic health record review. Fecal immunochemical test (FIT), fecal occult blood test \[FOBT\], fecal immunochemical test - deoxyribonucleic acid (FIT-DNA), colonoscopy, flexible sigmoidoscopy, flexible sigmoidoscopy with FIT, Computerized Tomography colonography."
Time frame: Up to 6 months after randomization
Proportion of Subjects Who Returned a Completed Mailed FIT at 60 Days
The proportion of subjects who received study Intervention (Age Group - 50-75) and returned a completed FIT per electronic health record review.
Time frame: Up to 60 days after randomization
Proportion of Subjects Who Completed a Follow-up (Diagnostic) Colonoscopy
The proportion of subjects who received study Intervention (Age Group 50-75) and did not receive study information (Usual Care only - Age Group 50-75), who had a positive (abnormal) FIT/FOBT result, and for whom colonoscopy was deemed to be clinically appropriate by the subject's provider, who completed follow-up (diagnostic) colonoscopy per electronic health record review.
Time frame: Up to 6 months after diagnostic colonoscopy referral date
Number of Subject Colorectal Carcinoma (CRC) and Advanced Adenomas Detected at 12 Months
Number of CRCs and advanced adenomas detected among subjects who received study Intervention (Age Group 50-75) and subjects who did not receive study intervention (Usual Care only - Age Group 50-75) per electronic health record review.
Time frame: Up to 12 months after screening or diagnostic colonoscopy result date

Subjects are mailed an introductory letter advising them that they will receive a FIT kit in the mail. Next, subjects are mailed a FIT packet in plain envelope that contains a cover letter, CRC information sheet, FIT instruction sheet, and FIT kit with a pre-paid return envelope. The plain envelope is a white envelope without a USPS tracking label or sticker message. Subjects receive up to two mailed letters reminding them to complete and return the FIT. Subjects receive FIT results via letter or phone call.
Number of Days From CRC Diagnosis to the Date of Evaluation for CRC Treatment
Number of days from CRC diagnosis to the date of evaluation for CRC treatment among subjects who received study Intervention (Age Group 50-75) and subjects who did not receive study intervention (Usual Care - Age Group 50-75) using electronic health record data to ascertain the dates of CRC diagnosis and evaluation for CRC treatment.
Time frame: Up to 12 months after CRC diagnosis
Number of Subjects Who Received Referral for Cancer Treatment
Number of subjects who received study Intervention (Age Group 50-75) and did not receive intervention (Age Group 50-75) who received referral for cancer treatment among individuals diagnosed with CRC per electronic health record review.
Time frame: Up to 6 months after cancer diagnosis date
Number of Subjects Mailed FITs Completed After Two Rounds of Annual FIT Outreach
"Number of annual FIT screenings completed (0, 1, or 2) by subjects who received Intervention (Age Group 50-75) after two annual rounds of mailed FIT outreach per electronic health record review.
Time frame: Round 1 time frame: at 6 months after randomization; Round 2 time frame: at 6 months after determining eligibility for Round 2
Incremental Cost of Each Additional Patient Screened in the Intervention Arm Compared to Usual Care (Trial - Age Group 50-75)
Comparison of the programmatic costs incurred and number of subjects screened in Arm 1(Trial Mailed FIT Intervention - Age Group 50-75) compared to Arm 2 (Trial Usual Care - Age Group 50-75), measured as cost of intervention minus the cost of usual care, divided by the number screened in Arm 1 minus the number screened in Arm 2. Intervention costs will be assessed using periodic episodes of direct observation of mailed FIT outreach activities, time logs maintained by the intervention team, and assembly of administrative data capturing non-personnel/non-labor expenditures, such as costs associated with materials printing, FIT processing, and mailing costs. Usual care costs will be assessed using a combination of clinic observations and interviews with staff.
