About this study
Official title: The Effect of Bowel Preparation Training Given to Patients Planned to Undergo Colonoscopy and the Monitoring Carried Out by the Nurse on Anxiety, Compliance With Bowel Preparation and Bowel Cleansing
This study was planned to examine the effect of bowel preparation training and monitoring given to patients planned to undergo colonoscopy on the level of anxiety, compliance with bowel preparation and bowel cleansing. The research sample was collected at the Sultan II. University of Health Sciences affiliated to the Istanbul Provincial Health Directorate between December 2022 and August 2023. 34 intervention and 34 control groups will be randomly selected from outpatients who apply to the Colonoscopy Unit of Abdülhamid Han Training and Research Hospital and meet the inclusion criteria.
In this study, it is aimed to increase the effect of bowel preparation training, supported by nurses in the clinic and via instant messaging/calling or communication application, on patients' anxiety level, level of compliance with bowel preparation, and bowel cleansing in patients scheduled for colonoscopy.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Intervention group: nurse-led education for bowel preparation of colonoscopyOther
- PRE-TEST
- Patients will be evaluated using the Patient Information Survey, Procedure Compliance Survey and Beck Anxiety Scale.
- INTERVENTION
- Patients will be given face-to-face training in the clinic training room of the unit.
- After face-to-face training is given, an educational brochure will be given to the patient.
- If the patient is constipated, the bowel preparation diet is requested to be started 5 days in advance. If the patient is not constipated, the bowel preparation diet is started 3 days in advance.
- After the intervention group is given bowel preparation training, reminders about colonoscopy will be made via instant messaging 3 to 5 days before the day of the colonoscopy.
- LAST TEST
- Data will be collected again using the Patient Information Survey, Procedure Compliance Survey and Beck Anxiety Scale.
- The cleanliness of the intestines will be evaluated by the physician using the Ottawa Bowel Preparation Scale.
| Study group | Role | What they receive |
|---|---|---|
| Control Group: Data Collection | Other | 1. PRE-TEST
a) Who is decided to have a colonoscopy, using the Patient Information Survey, Procedure Compliance Survey and Beck Anxiety Scale.
2. ROUTINE APPLICATION
1. Patients who are planned to undergo colonoscopy and are included in the control group will be trained according to the bowel preparation protocol routinely applied by the clinical nurse.
2. The Procedure Compliance Survey, which is routinely used as a clinical procedure, is given to the patient/patient's relative after the training of the clinical nurse.
3. FINAL TEST
1. Immediately after the procedure, data will be collected again with the Patient Information Survey, Procedure Compliance Survey and Beck Anxiety Scale.
2. After the procedure, the cleanliness of the intestines will be evaluated by the physician with the Ottawa Bowel Preparation Scale.
3. The control group will be given training and a booklet after all data collection is completed. Receives: Other: Intervention group: nurse-led education for bowel preparation of colonoscopy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Patient Information Survey
It includes data about the personal characteristics
Measured: baseline, pre-intervention (pre-colonoscopy procedure)
Beck Anxiety Inventory
It measures the level of anxiety before colonoscopy prosedure
Measured: pre-intervention (pre colonoscopy procedure)
Procedure Compliance Survey
