Abstract

English

Background: A survey conducted by the European Society of Gastrointestinal Endoscopy (ESGE) highlights significant variability in the provision of medical information across Europe. Furthermore, it has been demonstrated that patients frequently leave consultations feeling inadequately informed, with such dissatisfaction being cited as a contributing factor to subsequent treatment errors. Full information on gastroscopy could provide a remedy here. This study aims to assess whether the incorporation of an additional educational video can reduce patient anxiety, enhance satisfaction, and minimize the required sedation. Methods: This is a duocentric prospective randomized study. Before and after receiving the self-created video, both groups completed a specially standardized questionnaire. At the end, descriptive statistic was calculated, and the two groups were compared with each other. Results: A total of 311 participants were enrolled (intervention group (n=127, Group A) and the control group (n=124, Group B)). The educational video, viewed prior to the medical consultation, significantly alleviated subjective anxiety (p<0.001) to a degree comparable to the conventional consultation alone. Moreover, 88% of patients rated the video as a useful or highly beneficial addition to their education. There was no difference in the sedation between the two groups (p = 0.176, 95%KI [-13.5,37.6]). Conclusion: The educational video represents an effective adjunct to the standard educational interview, enhancing the clarity and comprehensibility of pre-procedural information. It similarly reduces anxiety to the same extent as a direct explanation by the physician, and as such, can be recommended as a valuable supplement in routine clinical practice. The dosage of propofol is not affected.
