Abstract

BACKGROUND/AIMS:

The preparation-to-colonoscopy (PC) interval is one of several important factors for the bowel preparation. Short message service (SMS) reminder from a cellular phone has been suggested to improve compliance in various medical situations. We evaluated the effectiveness of SMS reminders to assure the PC interval for colonoscopy.

METHODOLOGY:

This prospective randomized study was investigator blinded. In the No-SMS group, patients took the first 2 L polyethylene glycol (PEG) between 6 and 8 PM on the day before colonoscopy and the second 2 L PEG approximately 6 hours before the colonoscopy without SMS. In the SMS group, patients took first 2 L PEG in the same manner as the No-SMS group and the second 2 L PEG after receiving an SMS 6 hours before the colonoscopy.

RESULTS:

The SMS group had a lower score than the No-SMS group, according to the Ottawa Bowel Preparation Scale (P < 0.001). Multivariate logistic regression analysis showed that compliance with diet instructions (odds ratio (OR) 2.109; 95% confidence interval (CI), 1.11-3.99, P = 0.022) and intervention using SMS ((OR) 2.329; 95% (CI), 1.34-4.02, P = 0.002) were the independent significant factors for satisfactory bowel preparation.

CONCLUSIONS:

An SMS reminder to assure PC interval improved the bowel preparation quality for colonoscopy with bowel preparation.
