Effect of Enhanced Interactive Text Messages and Phone Instruction on the Quality of Bowel Preparation for Colonoscopy.

This is a prospective, randomized, controlled clinical investigation designed to evaluate the efficacy of enhanced bowel preparation instructions (automated SMS, information website, and pre-recorded phone call) in improving bowel preparation quality in elective colonoscopy.

Subjects from the interventional and control group will receive standard of care bowel preparation instruction.

The interventional group will receive enhanced instructions delivered by automated SMS, information website and pre-recorded phone calls in the 48 hours leading up to the colonoscopy day. The intention is to provide a reminder, to reiterate instruction on clear fluid diet and timing of bowel preparation medication, and to provide additional graphical illustration on the information website.

Subjects in the interventional group must reply "OK" to each automated SMS or press "1" on the keypad at the end of the automated phone call to acknowledge understanding and receipt of instruction. Failure to acknowledge trigger an alert for a booking office staff member to directly call the patient and confirm compliance.

The clinical investigation will be conducted at one hospital in the state of New South Wales, Australia.

Subjects will be randomized to the interventional group (enhanced instruction) versus the control group (standard instruction).

The proceduralist assessing outcome measures at the time of colonoscopy is blinded to the intervention.
