Colorectal Cancer Screening Preventive Reminder Ordering AssistanCe Via Texting for Improved Visit Encounters

A substantial portion of the United States population remains overdue for preventive care screenings, despite availability of health services. This gap in care persists due to both patient and clinician facing barriers. Patients may not always remain actively engaged with their care team, while clinicians are impacted by time constraints and the complexity of managing multiple care tasks during visits. One population health strategy to address these barriers is visit-based nudges, which are anchored around office visits and use methods such as post-visit texting to patients. One study aimed at improving colorectal cancer screening rates uses visit-based outreach, in addition to direct outreach, to offer patients colonoscopy and fecal immunochemical tests (FIT), which are top tier tests for CRC screening. Another prior study, aimed at improving mammogram completion, utilized pended orders and post-visit texting to increase screening rates by 5 percentage points at six months for intervention patients. Both studies have highlighted the need to create a scalable program for a cohesive patient experience. Building upon our prior and current work and in collaboration with primary care, we propose to develop and evaluate an integrated visit-based preventive health program with nudges to patients using a stepped wedge design, with the goal of implementing this system across primary care practices. This trial will run concurrently with another trial, PROACTIVE (IRB #589571), evaluating pre-visit and post-visit nudges to clinicians and patients to increase screening completion for multiple care gaps identified as high priority by primary care. Because this trial only utilizes post-visit text messaging to the patient and no clinician nudge, it will be a distinct analysis and considered a separate trial.
