Conditions

Colorectal Cancer

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.

Interventions

BEHAVIORALText Message Instructions/Motivation

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.

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 outcomes

Primary

MeasureTime frameDescription
National Annie Colonoscopy Survey ScoreDay 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.

Text Message Intervention
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. Text Message Instructions/Motivation: 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.

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.

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

Population: Control patients were not given text messaging intervention, therefore did not participate in the Annie text message survey. All intervention patients were encouraged to complete the survey, and 16 of 25 did.
