Text Messaging to Improve Adherence To Repeat Colonoscopy In a Veterans Affairs (VA) Hospital

Study Overview
=================
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.

Official Title

Colorectal Cancer

Intervention / Treatment

* Behavioral: Text Message Instructions/Motivation


Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: • Has previously undergone a colonoscopy and is currently due for a repeat screening or surveillance colonoscopy at the VA. Exclusion Criteria: 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.

Design Details

Primary Purpose: Screening
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Text Message Intervention<br>Participants 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. | Behavioral: Text Message Instructions/Motivation<br>* 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.<br>|
| No Intervention: No Intervention<br>Participants will not receive text messages. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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 Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants who Attend Scheduled Colonoscopy Appointment | Assessed via patient's electronic health record. | Up to Day 14 | 
| Percentage of Participants who Had Adequate Bowel Preparation at Colonoscopy Appointment | Assessed via patient's electronic health record. | Up to Day 14 |
