Using A Customized SMS Program to Promote Colonoscopy Adherence and Support Bowel Cleanliness for Spanish-speaking Patients.

INTRODUCTION: Low colorectal cancer (CRC) screening rates among Hispanic and Latino patients result in advanced disease at the time of diagnosis and decreased survival chances. METHODS: We performed a prospective study at an academic endoscopy center in Boston, Massachusetts from May 1, 2019 to January 31, 2020. We identified 887 Spanishspeaking patients as controls and enrolled 412 (59%) Spanish-speaking patients in a short message service (SMS) program for pre-procedure instructions. RESULTS: Intervention and control group participants were similar in age, sex, and indications. Patients receiving SMS messages were less likely to no-show or cancel last minute (OR=1.66, 95%CI=0.44-0.83, p=.002) and had more adequate bowel preparations compared with the control arm (OR=1.55, 95%CI=0.45-0.92, p=.01). Overall, 93% (117/126) of patients stated they would "highly recommend" the program to others. CONCLUSIONS: Our automated SMS reminders for colonoscopy preparation increased appointment adherence, bowel preparation quality, and showed good patient satisfaction among Spanish speakers.
