Brief Summary
Colorectal cancer is a common but preventable condition, and increasing colorectal cancer screening is one of the most impactful public health contributions in the field of gastroenterology. Text messaging is a simple, cheap, and rapid method to reach patients that may improve adherence to colonoscopy appointments as well as simplify the process of bowel preparation. The purpose of the study is to evaluate the feasibility of a pilot bidirectional text messaging intervention on attendance for screening/surveillance colonoscopy and bowel preparation quality at an urban VA hospital. The goal is to improve adherence to colonoscopy among patients who are due for a repeat colonoscopy.

Outcome Measures
Primary Outcomes (1)
National Annie Colonoscopy Survey Score
7-item assessment of participant satisfaction with the "Annie" text intervention. Items are rated on a 5-point scale from 1 (strongly disagree) to 5 (strongly agree). The total score is the sum of responses and ranges from 7 to 35; higher scores indicate greater satisfaction with the intervention.
Day 21 (Up to 7 Days Post-Procedure)
Secondary Outcomes (2)
Percentage of Participants Who Attend Scheduled Colonoscopy Appointment
Up to Day 14
Percentage of Participants Who Had Adequate Bowel Preparation at Colonoscopy Appointment
Up to Day 14
Study Arms (2)
Text Message Intervention
EXPERIMENTALParticipants in the experimental arm will receive a series of instructional and motivational text messages, which will be sent starting 7-14 days before and until the day of the colonoscopy procedure.
No Intervention
NO INTERVENTIONParticipants will not receive text messages.
Interventions
For instructional messages, earlier messages will remind patients of the colonoscopy appointment and later messages will help patients complete the bowel preparation process in real-time. Motivational messages will be sent along with instructional messages.
Eligibility Criteria
You may qualify if:
- Has previously undergone a colonoscopy and is currently due for a repeat screening or surveillance colonoscopy at the VA.
You may not qualify if:
- Patients not due for screening or surveillance colonoscopy. This will be based on 2020 guidelines from the U.S. Multi-Society Task Force on Colorectal Cancer.
- Patients with personal history of colorectal cancer (CRC)/inflammatory bowel disease/ hereditary colon cancer syndrome or family history of hereditary colon cancer syndrome. These criteria will be determined based on ICD9/10 codes or the medical record.
