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

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.

Treatment and study plan

Text Message Instructions/Motivation

Behavioral

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.

Primary outcomes

  1. National Annie Colonoscopy Survey Score

    Time frame: Day 21 (Up to 7 Days Post-Procedure)

    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.

Secondary outcomes

  1. Percentage of Participants Who Attend Scheduled Colonoscopy Appointment

    Time frame: Up to Day 14

    Assessed via patient's electronic health record.

  2. Percentage of Participants Who Had Adequate Bowel Preparation at Colonoscopy Appointment

    Time frame: Up to Day 14

    Assessed via patient's electronic health record.
