Effect of Text Messaging on Bowel Preparation and Appointment Attendance for Outpatient Colonoscopy

Key Points Question Do automated text messages improve outpatient colonoscopy attendance rate and bowel preparation quality? Findings In this randomized clinical trial including 753 patients, usual care patient instructions were compared with an automated text messaging intervention in the week prior to outpatient colonoscopy. There was no significant difference between groups in appointment attendance rate or bowel preparation quality. Meaning This randomized clinical trial found that automated text message reminders and instructions did not improve outpatient colonoscopy adherence, although future studies may identify patient subgroups that benefit from this approach.
