Brief Summary

Colonoscopy is the examination of the large intestine with an instrument called a colonoscope. To make an accurate evaluation during a colonoscopy performed for diagnosis and treatment, adequate preparation of the large intestine must be made. Information given to patients is very important for adequate bowel preparation and adherence to treatment. Therefore, this study was planned as a prospective, single-blind randomized controlled study to determine the effect of mobile application-based bowel preparation training on patients' bowel preparation compliance, quality and anxiety level in patients scheduled for colonoscopy. The study will be carried out with 160 patients (experimental: 80, control: 80) who will apply to the Istanbul University Istanbul Medical Faculty Hospital General Surgery Department Endoscopy Unit, who will undergo colonoscopy as an outpatient. Both groups will receive oral and written instructions for bowel preparation. In addition, the smart phone app group will received instructions through a medical smart phone app. The primary outcome was the rate of adequate bowel preparation according to the Boston bowel preparation scale score. The secondary outcomes included patient compliance.

Outcome Measures

Primary Outcomes (1)

• quality of bowel preparation

  The Boston bowel preparation scale is a four-point (0-3) assessment tool for bowel cleansing administered separately for each of the three sections of the colon during colonoscopy.Each region of the colon receives a "segment score" from 0 to 3 and these segment scores are summed for a total Boston bowel preparation scale score ranging from 0 to 9. Therefore, the maximum Boston bowel preparation scale score for a perfectly clean colon without any residual liquid is 9 and the minimum Boston bowel preparation scale score for an unprepared colon is 0.

Secondary Outcomes (1)

• Anxiety

  will be administered to patients before colonoscopy

Study Arms (2)

Experimental Group

EXPERIMENTAL

Patients using mobile application as well as verbal and written information in bowel preparation training in patients who will undergo colonoscopy will constitute the experimental group.

Behavioral: Mobile Application-Based Bowel Preparation Training

Control Group

NO INTERVENTION

Patients who will be given oral and written information in bowel preparation training in patients who will undergo colonoscopy will form the control group.

Interventions

Mobile Application-Based Bowel Preparation Training BEHAVIORAL

The contents of the training in the mobile application where the patients receive bowel preparation training before the procedure are; short videos, images and slides about colonoscopy, bowel preparation drugs, liquid-clear diet and foods recommendations.A mobile application-based training will be provided to guide patients, where user (patient) usage activities are monitored by the researcher, sending notifications or reminders to the patient in accordance with the colonoscopy procedure date.
