Intervention group; counselling with visual aid
First of all, counselling was done in which patients were given a briefing about the procedure; the use of local anesthetic along with potential benefits and side effects of the drug. The steps of the endoscopy procedure (gastroscopy or colonoscopy) were explained in detail including the position, intubation, biopsy or intervention wherever applicable, extubation and post-procedure observation period in the recovery room. Detailed instructions were provided regarding post-procedural care, introduction of diet & follow-up. In addition to that, video education was provided. During video education, patients watched a 2-min video of the respective procedure. Video showed the animation of a gastroscopy or colonoscopy procedure with a voice over explaining all the steps of the procedure in addition to the pre- and post-procedure precautions to be observed [
