- Abstract
Introduction: Due to a lack of time and staff, informed consent (IC) in clinical practice often lacks clarity, comprehensibility and scope of information. Digital media offer great potential to enhance IC. Aim of this study is to evaluate the effectiveness of multimedia-supported compared to traditional paper-based IC., Methods: In the randomized, controlled, three-arm DICon (Digital Informed Consent for urological surgery) study 70 patients with an indication for prostate biopsy were randomized 1:1:1 to receive traditional paper-based IC vs. multimedia-supported information before IC vs. multimedia-supported information during IC. Patient satisfaction, anxiety and information gain were measured by validated questionnaires 2 weeks and directly before the procedure and time efficiency was recorded. Statistical analysis was performed using Kruskal-Wallis and Dunn's test (one-way ANOVA) and two-way ANOVA (with bonferroni post-test)., Results: Multimedia information prior to the consultation saved 32.9% time compared to paper-based (5.3 min. vs. 9.5 min; p < 0.05) and 60.4% time compared to shared multimedia information (5.3 min. vs. 13.9 min.; p < 0.001), with no difference in satisfaction (62.6 vs. 62.7 vs. 68.6 of max. 80; p = 0.07), anxiety (8 vs. 8.1 vs. 7 of max. 16; p = 0.35), or information gain (6.5 vs. 5.7 vs. 6.7 of max. 10; p = 0.23). Results on satisfaction (56.6 vs. 62.6 vs. 66; p = 0.06), anxiety (7.2 vs. 7.2 vs. 6.8; p = 0.84), and information gain (7 vs. 6.4 vs. 5.9; p = 0.43) remained stable over time., Conclusions: Multimedia-supported IC prior to consultation provided improved time efficiency (33% gain) compared to traditional paper-based IC, with comparable satisfaction, anxiety and information gain. Multimedia-supported information materials should therefore be used more frequently in patient education., (© 2023. The Author(s).)
