SP8.10 - Systematic Review and Meta-Analysis of Interactive multimedia Interventions used in the Informed Consent Process

Abstract

Abstract Aim The use of digital technology to improve the informed consent process has increased over the past decade. A wide range of multimedia modalities are now available. This review aimed to assess the impact of interactive multimedia interventions on the informed consent process. Methods This was a subgroup analysis of a larger systematic review and meta-analysis conducted in accordance with a predefined protocol registered on PROSPERO (CRD42023380406). Five databases were searched using pre-defined search criterion in December 2022 for randomised trials of interactive multimedia interventions designed to improve the informed consent process. Adults >18 years undergoing invasive interventions with the capacity to consent were included. The Cochrane Risk of Bias (RoB) tool was used to assess study quality. Standardised mean difference for continuous variables and risk ratios for dichotomous variables were used to assess effect. Meta-analyses were performed in RevMan5. Results 21 studies (22 interventions arms) with 2090 participants were included. All studies involved patients undergoing informed consent in an elective hospital setting for various surgical, cardiological and radiological procedures. Statistically significant improvement in immediate (SMD 0.40, 95% CI 0.18 to 0.62, I2=55%) and short-term knowledge (SMD 0.47, 95% CI 0.16 to 0.79, I2=45%) were demonstrated. No statistically significant differences were found for long term knowledge, generalised anxiety, satisfaction with the consent process or length of consultation. Conclusions Interactive multimedia interventions improve immediate and short-term knowledge in patients undergoing invasive interventions and could be considered as an adjunct to enhance patient knowledge during the informed consent process.
