Effect of interactive, multimedia-based home-initiated education on preoperative anxiety inchildren and their parents: a single-center randomized controlled trial

Abstract

BackgroundAnesthesiologists need to appreciate the impact of preoperative anxiety in children. The present study aimed to explore whether interactive multimedia-based home-initiated interventions could effectively relieve preoperative anxiety in pediatric patients.MethodsIn this prospective study, we compared preoperative anxiety between two groups of children aged 4–9 years. Children in the control group received a question-and-answer (Q&A) introduction, and children in the intervention group received multimedia-based home-initiated preoperative education using comic booklets, videos, and coloring game books. Differences in anxiety between the two groups were evaluated by the modified Yale Preoperative Anxiety Scale-Short Form (mYPAS-SF) at four time points: in the ophthalmology outpatient clinic before intervention as the baseline (T0); in the preoperative waiting area (T1); at the time of separating from their parents and moving to the operating room (T2); and at the time of anesthesia induction (T3). Parental anxiety was assessed by the Self-rating Anxiety Scale (SAS) and Visual Analog Scale (VAS) at T0 and T2. Other related information was collected by questionnaire.ResultsEighty-four children who underwent pediatric strabismus in our center between November 2020 and July 2021 were included in this study. An intention-to-treat (ITT) analysis was performed on data from 78 enrolled children. Children in the intervention group exhibited lower m-YPAS-SF scores at T1, T2, and T3 than those in the control group (all p < 0.001). By using a mixed-effect model with repeated measurement (MMRM) after adjusting the m-YPAS score at T0 as a covariate, the interventional effect in terms of themYPAS-SF score was also significant over time (p < 0.001). The percentage of children with perfect induction compliance (ICC = 0) in the intervention group was significantly higher than that in the control group [18.4% vs. 7.5%], and poor induction compliance (ICC>4) was lower (2.6% vs. 17.5%, p = 0.048). The mean parental VAS score at T2 in the intervention group was significantly lower than that in the control group (p = 0.021).ConclusionsInteractive multimedia-based home-initiated intervention could reduce preoperative anxiety in children and improve the quality of anesthesia induction based on ICC scores, which may in turn impose a positive impact on parental anxiety.
