Effect of Multimedia Teaching Tools in Parental Anxiety and Comprehension of Informed Consent Procedure in Pediatric Surgical Procedures: A Single Centre Randomized Control Trial

Introduction: Informed consent is an essential component of medical ethics. In children, the parent or legally authorized guardian must consent to any medical or surgical intervention. A number of adjuncts have been developed to supplement the consent process including multimedia tools. Unfortunately, there is little information regarding the use of Multimedia teaching tools (MMT) in pediatric settings in developing countries with diversities in language, socioeconomic and educational status.Objectives: The objectives of the study were to compare the parental comprehension of the surgery through the informed consent obtained either by conventional method or by multimedia tool and the effect of MMT in alleviating parental anxiety against the conventional method and to assess their overall satisfaction.Methods: A randomized control trial was conducted between 2018 and 2020, including MMT and conventional groups. A novel Multimedia tool with a Microsoft PowerPoint presentation was created. A 5Question knowledge-based test, State-Trait Anxiety Inventory (STAI) tool, and a Likert-based questionnaire were used to assess the comprehension, anxiety, and satisfaction of parents.Results: Among 122 randomized cohorts, the mean value of percentage fall in anxiety STAI score in the MMT group was 44.64 +/- 10.14 whereas in the Conventional group it was 26.6 +/- 11.91 (p < 0.05). MMT cohort scored higher in the knowledge-based test (p < 0.05) and recorded higher parental satisfaction.Conclusion: The Multimedia tool aided consent procedure is effective in reducing parental anxiety and improving their comprehension and overall satisfaction. Thus, they can be used as an effective supplement in preoperative surgical education and consent procedure.Level of evidence: Level I.(c) 2023 Elsevier Inc. All rights reserved.
