Study Summary
This is a pragmatic, randomized, controlled trial of a geographically randomized intervention in which all eligible patients will receive a mailed fecal immunochemical test (FIT) kit (the GeoMail study). In this study, all ZIP Codes in Dallas County will be randomized to either treatment or usual care. Patients in treated neighborhoods will receive kits at the same time; patients in usual care neighborhoods will receive FIT kits randomly throughout the year. All eligible patients will receive a FIT kit each year. The trial will be conducted in a racially and socioeconomically diverse cohort of patients served by an integrated safety net delivery system. This study represents a pragmatic adaptation to the "FIT first" population health screening strategy in which all eligible patients are mailed FIT kits. All patients will also have access to whatever colorectal cancer (CRC) screening is recommended through usual visit-based care.
Primary Outcome
Defined as screening completed within 6 months of when the FIT kit is mailed for each patient by any recommended screening modality (FIT, colonoscopy, sigmoidoscopy; i.e., the proportion of treated vs. usual care patients who have completed screening). Screening will be measured using electronic medical record procedure, result, and billing data (Parkland-specific, CPT, ICD9/10 codes) and will be considered complete when satisfactory (e.g., adequate sample collection) FIT or colonoscopy test res
