Study to Increase Colorectal Screening

August 30, 2025 updated by: Samir Gupta, University of California, San Diego

A RCT of Outreach and Inreach Strategies for Boosting CRC Screening in a Federally-Qualified Health Center

The purpose of this study is to determine whether inreach and outreach strategies will be superior to usual care, and combination of both will be superior to either strategy alone.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Colorectal cancer (CRC) screening saves lives, but screening rates are low among underserved populations, particularly Latinos. The screening rate in the predominantly Latino population served by San Ysidro Health Center (SYHC, a Federally Qualified Health Center (FQHC)), is just 31%, similar to that reported for Latinos nationally, but lower than the overall national average of 65%. Previous research has demonstrated that inreach interventions at point of medical care such as patient navigation after screening referral, and outreach outside of usual medical care (such as with mailed invitations) can increase screening rates among underserved populations. However, since these have undergone limited evaluation among low income predominantly Spanish-speaking Latinos, it is unclear which approach is best, and whether implementing both approaches would be synergistic for optimizing screening rates. We hypothesize that two culturally and linguistically tailored interventions: a) an inreach strategy (IR, consisting of community health worker-delivered in clinic education regarding CRC screening and other components), and b) an outreach strategy (OS, consisting of mailed invitations to complete screening with an enclosed fecal immunochemical test (FIT) and telephone reminders) can substantially increase screening, and further, that the two interventions together will be substantially better than either alone. To test these hypotheses, we propose a randomized trial comparing usual care, IR, OS, and IR+OS for CRC screening.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
673

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Individuals age 50 to 75 years,
  • One or more SYHC visits in the last year,
  • Not uptodate with CRC screening

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Inreach strategy
This consists of a community health worker-delivered in clinic education regrading CRC screening with a fecal immunochemical test (FIT) kit, and telephone reminders.
Behavioral: Inreach strategy
Inreach strategy: In clinic education and delivery of fecal immunochemical test (FIT) kit
Experimental: Outreach strategy
This consists of mailed invitations to complete screening with an enclosed fecal immunochemical test (FIT) kit and telephone reminders.
Behavioral: Outreach strategy
Outreach strategy: Mailed fecal immunochemical test (FIT) kit and telephone reminders
Experimental: Both Inreach and Outreach strategies
This is a combination of the above two strategies: Inreach and Outreach combined.
Behavioral: Both Inreach and Outreach strategies
Both Inreach and Outreach strategies: Both In clinic education and delivery of fecal immunochemical test (FIT) kit and Mailed fecal immunochemical test (FIT) kit and telephone reminders
Active Comparator: Usual care
Usual care in the clinic using the fecal immunochemical test (FIT) kit.
Behavioral: Usual care
Usual care: FIT kit delivery as part of usual care

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
