A Randomised Control Trial: Effectiveness of a Video Assisted Teaching on Knowledge, Anxiety, Physiological and Behavioural Responses of Patients Undergoing Gastroscopy

Information is one of the important resources for coping and it can alter the subject's feeling of the threat and thus enhances compliance. Inadequate information regarding gastroscopy may cause severe anxiety, fear, and poor compliance and reduce the patient's tolerance. An experimental design was used in this study to assess the effectiveness of a video assisted teaching on knowledge, anxiety, physiological and behavioural responses of patients undergoing gastroscopy. The study was conducted in Christian Medical College, Vellore. A total of 72 subjects were selected by block randomization technique who fulfilled the inclusion criteria and their consent was obtained. On the day of appointment, State Trait Anxiety Inventory (Y1) was used to assess the anxiety and questionnaire prepared by the investigator to assess the knowledge regarding gastroscopy, its preparation and complications. For experimental group, the video was played and control group received routine information. On the day of gastroscopy procedure, same questionnaire was used to assess their anxiety and knowledge. Physiological responses were assessed before and during procedure. Behavioural responses were assessed during procedure using checklist. Pain was assessed post-procedurally. Most of the subjects (68.1%) were male, 83.3% were married. There was a statistically significant increase in mean scores of knowledge from 4.55 to 12.38 in experimental group (p<.001). There was a statistically significant decrease in mean scores of anxiety from 42.83 to 35.75 in experimental group (p<0.001). The study revealed that providing structured teaching using video will help the patient to increase their knowledge and reduce anxiety.
