Effect of multimedia teaching tools in parental anxiety and comprehension of informed consent procedure in pediatric surgical procedures

Abstract

Introduction: Informed consent is an essential component of medical ethics. A number of adjuncts have been developed to supplement the consent process, which includes informational pamphlets, and multimedia tools such as interactive apps and videos. Unfortunately, there is little information regarding the use of Multimedia tools in pediatric settings in the developing world. The purpose of this study was to measure the impact of Multimedia tool-assisted versus the conventional consenting method on parental anxiety and their comprehension of surgical procedures. Methods: A randomized control trial was conducted between 2018-2020, including MMT and conventional groups. A novel Multimedia tool with Microsoft PowerPoint presentation was created. A 5-Question 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.
