Brief summary
This is a randomized controlled trial designed to assess the efficacy of a novel smartphone application as an automated reminder tool in improving the quality of bowel preparation for patients undergoing outpatient colonoscopies. The investigators will be comparing the smartphone application to traditional instructions for bowel preparation. The quality of bowel preparation will be assessed using the Ottawa and Aronchick bowel preparation scales.
Detailed description
This is a randomized controlled trial designed to assess the efficacy of a novel smartphone application as an automated reminder tool in improving the quality of bowel preparation for patients undergoing outpatient colonoscopies at an academic teaching hospital in Kingston, Ontario. The intervention under investigation is the use of a novel smart phone application which serves as an automated reminder system for patients undergoing outpatient colonoscopies. The application requires the patients to enter the date and time of the colonoscopy appointment and automatically populates the patients' phones with calendar reminders as well as pre-recorded messages regarding cessation of solid food intake, the need for clear fluid intake, as well as timing of their bowel regimens starting 7 days prior. The design of this study is a prospective, randomized controlled trial with single blinding (endoscopist). Eligible participants will be randomized into either the control (routine paper instructions) or the intervention group (smart phone application). Those who are randomized into the intervention group will be provided with specific instructions to download and setup the smart phone application at least 7 days prior to their scheduled appointment. Upon arrival to their appointment, participants in both groups will be asked to complete a survey confirming the adherence to either paper instructions or instructions provided by the smart phone application. The primary outcome of this study is the adequacy of the bowel preparation, as assessed by using the Ottawa and Aronchick bowel preparation scales, which have been previously validated and are in common usage for colonoscopy procedures. Secondary outcomes include rate of polyp detection, rate of cecal intubation, and patient reported ease of use and adherence to the bowel regimen instructions.
Interventions
OTHERBowel Preparation
Bowel Preparation is completed prior to colonoscopy to ensure adequate visualization of the bowel lumen. This requires diet modifications and taking of medications at specified time intervals.

Masking description
Patients will be aware of the arm they were assigned to. Colonoscopist performing the colonoscopy will be masked to the intervention and will be providing the assessment of the quality of bowel preparation. The investigators will be masked to the assignment.
