Poster Session I - A64 ENHANCING INFORMED CONSENT: A SYSTEMATIC REVIEW AND META-ANALYSIS OF VIDEO- AND COMPUTER-BASED APPROACHES COMPARED WITH CONVENTIONAL METHODS

Background Informed consent is a critical component of patient-centered care. Traditional consent processes may not always optimize patient comprehension, satisfaction, or anxiety reduction, due to time constraints. Video- or computer-based consent interventions have emerged as potential tools to enhance these outcomes. Aims To systematically review and synthesize evidence comparing video/computer-based consent processes with standard or conventional consent approaches, focusing on patient knowledge, satisfaction, and anxiety. Methods A comprehensive search was conducted in MEDLINE, Embase, and the Cochrane Library. Eligible studies included randomized controlled trials and comparative studies evaluating video/computer-based versus conventional consent methods. Primary outcomes were patient knowledge, satisfaction, and anxiety. Risk of bias was assessed using standardized tools, and pooled analyses were performed where data permitted. Results A total of 376 studies were identified through database searching, of which 9 studies met inclusion criteria. Compared with standard consent, video/computer-based interventions significantly improved patient knowledge (OR 2.21, 95% CI 1.72-2.84, I2 = 87%). Patient satisfaction was also higher with video/computer-based methods, but not significant (OR 1.35, 95% CI 0.87-2.10, I2 = 67%). Anxiety levels showed significant difference/reduction between groups (OR 0.59, 95% CI 0.42–0.85, I2 = 0%). The overall risk of bias was moderate, with frequent limitations in blinding and allocation concealment. Conclusions Video- and computer-based consent processes enhance patient knowledge and satisfaction without increasing anxiety. These findings support incorporating digital tools as effective adjuncts to conventional consent, though further high-quality studies with standardized outcome measures are needed.
