Sponsored by Sanko University · Not applicable, Interventional, and Prevention
This randomized controlled experimental study was conducted in the endoscopy unit of a private hospital between March and June 2023 to evaluate the effect of nurse-delivered counseling on pain, anxiety, and comfort levels in patients undergoing colonoscopy. Sixty patients were assigned to intervention (n=30) and control (n=30) groups. The intervention group received counseling beginning 24 hours before the procedure, including face-to-face education, telephone support, and reminder messages, while the control group received routine care. Anxiety was assessed using the State Anxiety Scale, and pain and comfort were evaluated using the Visual Analog Scale.
This randomized controlled experimental study was conducted in the endoscopy unit of a private hospital between March 2023 and June 2023. The study was designed to evaluate the effect of nurse-delivered online counseling on pain, anxiety, and comfort levels in patients undergoing colonoscopy. Sixty eligible patients were assigned to either an intervention group (n=30) or a control group (n=30) using the minimization method. Patients in the intervention group received online counseling based on standard colonoscopy preparation materials beginning approximately 24 hours before the procedure, including face-to-face education, telephone support, and reminder messages. Patients in the control group received routine care only. Anxiety was assessed using the State-Trait Anxiety Inventory, while pain and comfort were evaluated using the Visual Analog Scale. Outcome measures were collected before and after the colonoscopy procedure.

Time frame: Before and after colonoscopy procedure (same day)
Comfort Level
Measured using the Visual Analog Scale (VAS), a self-reported scale ranging from 0 to 10, where 0 indicates no comfort and 10 indicates maximum comfort. Higher scores indicate greater comfort.
