|Current Primary Outcome Measures ICMJE
||Colorectal Cancer Screening Participation, Defined as Completion of a Guaiac or Immunochemical Stool Occult Blood Test, Colonoscopy, Sigmoidoscopy, or Barium Enem. [ Time Frame: 1 year ] [ Designated as safety issue: No ]
To compare participation rates for screening between those receiving (a) mailed invitation to screening (immunochemical stool blood test (MailFIT) or colonoscopy(MailColo)) and (b) traditional visit-based screening (VisitBased), rates for these groups will be contrasted via a Chi-squared test. A p value<0.025 will be considered statistically significant.

Colon cancer (CRC) is a leading cause of cancer death in the United States. Screening can prevent CRC death, but screening rates are suboptimal, especially for vulnerable populations such as those with limited or no health insurance. This striking public health challenge demands urgent implementation of evidence-based strategies to reduce avoidable CRC death.
Prior research has shown that a direct-to-consumer strategy of inviting patients by mail to complete CRC screening may result in increased rates of screening completion. However, this approach has not been tested extensively in vulnerable populations, such as the under/uninsured, and minority populations often cared for by safety-net health systems. Further, it is unclear whether patients are more likely to participate in one CRC screening test versus another. Knowing this is important to designing programs for increasing screening. For example, the planning and resources required for a screening program with colonoscopy--which is a sensitive but invasive and expensive test--are very different from a program with that uses stool testing to detect microscopic blood such as an immunochemical stool blood test--which is a less sensitive, but non-invasive and cheap test.
Also, it is possible designing a program with a less sensitive, but more acceptable test could prevent more CRC death if participation in screening is test specific. For example, if many more patients participate in an immunochemical stool blood test based program than a colonoscopy based program, even though the immunochemical stool blood test is less sensitive, the program may save more lives because more patients are reached.
The aims of this trial are to:
Aim 1. Deliver CRC screening services (mailed invitation to screening, telephone reminders, and systematic clinical follow up) to uninsured, unscreened patients cared for by the safety-net health system serving Tarrant County, Texas. Patients will be invited to either:
Aim 2. Evaluate program outcomes, including screening rates, cancers detected, and program costs.
The primary outcome is screening completion.
Program setting. The John Peter Smith Hospital Health System (JPS) is a safety-net health care system serving Tarrant County, Texas (including Fort Worth), with over 850,000 yearly patient encounters. JPS qualifies as a safety-net health system based on a commitment to deliver health care to uninsured, Medicaid participants, and other vulnerable patients18, and is recognized as a disproportionate share hospital. JPS offers a tax-subsidized charity medical program called JPS Connection for uninsured Tarrant County residents who are not eligible for state or federal assistance programs such as Medicaid, with qualification based on federal poverty income levels.
Target population. Our specific project target population includes men and women, aged 54 to 64, without prior CRC screening, of all races/ethnicities (including African Americans, Hispanics, and Whites), who are primary English or Spanish language speaking, and uninsured but enrolled in the JPS Connection medical assistance program. We include only those individuals who qualify and are enrolled in the JPS Connection medical assistance program to ensure that all included patients have access to a primary provider, as well as surgical and medical cancer care, in the event that a patient has a cancer diagnosed.
TREATMENT (INTERVENTION) We will screen the administrative dataset that we are using to identify potential study participants for individuals who meet inclusion criteria. All patients selected to one of the programmatic screening approaches (Mailed FIT or Mailed Colonoscopy invitation) will receive the same, structured approach for encouragement of completion of CRC screening with the exception of the initial screening modality offered (e.g. FIT or colonoscopy). In addition, patients selected for program intervention will also be free to engage in usual medical care, and any associated visit-based screening at the discretion and preference of the individual and primary medical provider.
Mailed invitation program procedures. Every 3 months, ¼ of the patient group selected for the mail out program will receive an electronic, automated phone call, alerting them that an invitation to participate in CRC screening will be mailed to them shortly. All invitees, regardless of screen-group, will receive: 1) Invitation to participate in CRC screening with a specific test, including discussion of importance of screening, 2) Return card that may request to not participate in screening/be contacted in the future ("opt out" request). The invitations will be sent every 3 months in batches, rather than all at once, to allocate manpower resources for program follow up, and colonoscopy services as necessary for positive tests or screening requests.
Alert and reminder phone calls. At time of initial mailing of the invitation, a "TeleVox©" automated phone message, with a pre-recorded script (in both English and Spanish) will be generated to alert participants that an invitation is "in-the-mail." Fourteen days after initial mailing of the invitation, a "TeleVox©" automated reminder to respond to the invitation for screening with a pre-recorded script (in both English and Spanish) will be generated for all participants. Twenty-one to 36 days after initial invitation to testing, a "live" reminder phone call will be initiated by the screening coordination team for all individuals who have not responded to screening invitation. Up to 2 attempts will be made to contact individuals via phone; reaching a voice mail, an adult household member, or the target study participant will be considered a successful attempt. Reaching a disconnected, busy line, or line that rings with no answer on two attempts will be considered unsuccessful attempt. Continued intervention and follow up will not be based on whether or not phone call attempts were successful—all patients included in the program will be assessed for the outcome of screening participation.
Invitation letters. The invitation letters for screening with FIT or colonoscopy will contain the following elements: 1) Statement that risk of getting colon cancer increases with age and that screening can reduce the consequences, 2) Invitation to a specific modality, (FIT or colonoscopy) with a succinct description of the test, 3) Number to call with questions, 4) In the case of colonoscopy invitation, number to call to sign up, 5) Signature from a physician at JPS.
FIT procedures. Individuals assigned to FIT will be provided with written instructions on how to collect the stool samples for FIT testing. Kits will be mailed using return envelopes with pre-paid postage to a JPS.
Colonoscopy procedures. The colonoscopy invitation will consist of an explanation of colonoscopy, as well as a phone number to call to schedule a colonoscopy ("direct book") or a pre-colonoscopy clinic visit. The decision to "direct book" for colonoscopy or to arrange for a pre-colonoscopy clinic visit will be based on screening nurse phone interview using a short screening form. If potential medical contraindications to colonoscopy are noted, a pre-colonoscopy visit will be scheduled with a physician at JPS. Patients with uncontrolled medical conditions will be referred to primary physicians for further management and to consider CRC screening once the condition is under control. Reasons for not scheduling colonoscopy will be documented. The patient will receive a date and time assignment for the colonoscopy procedure, and instructions on bowel preparation for the procedure. The preparation kit will be mailed to the patient's home. Reminder calls 5-7 days prior to the procedure to confirm the date and time of the procedure, review bowel preparation instructions, and answer any questions will occur. The day of the procedure, a history and physical will be performed to re-assess for any contraindications for colonoscopy. Polyps identified will be removed completely, with repeat colonoscopy and/or surgery if polyp removal not successful. Any mass lesions and any areas of inflamed or irregular colon mucosa will undergo biopsy. Endoscopy findings will be reviewed with each participant.
Test Follow Up. Individuals with positive FIT will be contacted to schedule a colonoscopy, with the goal of test completion within 8-12 weeks of test positivity. If phone contact for test scheduling cannot be established, a certified letter will be sent. Individuals with findings of adenoma or cancer on colonoscopy will be scheduled for a follow up, post-colonoscopy visit with the endoscopist who performed the procedure. Individuals with normal FIT or colonoscopy screening tests will have a letter mailed to his or her home, as well as the primary outpatient clinic identified by administrative data.
