Virtual parental presence with coaching for reducing preoperative anxiety in children: a feasibility and pilot randomized controlled trial
Abstract
Background: Preoperative anxiety in children causes negative postoperative outcomes. Parental presence at induction is a non-pharmacological strategy for relieving anxiety; nevertheless, it is not always possible or effective, namely when parents are overly anxious. Parental presence via video has been demonstrated to be useful in other contexts (divorce, criminal court). This study reports the feasibility of a randomized controlled trial to investigate the effect of video parental presence and parental coaching at induction on preoperative anxiety. Methods: The study was a randomized, 2 × 2 factorial design trial examining parental presence (virtual vs. physical) and coaching (provided vs. not provided). Feasibility was assessed by enrollment rate, attrition rate, compliance, and staff satisfaction with virtual method with the NASA-Task Load Index (NASA-TLX) and System Usability Scale (SUS). For the children's anxiety and postoperative outcomes, the modified Yale Preoperative Anxiety Scale (mYPAS) and Post-Hospitalization Behavioral Questionnaire (PHBQ) were used. Parental anxiety was evaluated with the State-Trait Anxiety Inventory (STAI) questionnaire. Results: A total of 41 parent/patient dyads were recruited. The enrollment rate was 32.2%, the attrition rate 25.5%. Compliance was 87.8% for parents and 85% for staff. The SUS was 67.5/100 and 63.5/100 and NASA-TLX was 29.2 (21.5–36.8) and 27.6 (8.2–3.7) for the anesthesiologists and induction nurses, respectively. No statistically significant difference was found in mYPAS, PHBQ and STAI. Conclusion: A randomized controlled trial to explore virtual parental presence effect on preoperative anxiety is feasible. Further studies are needed to investigate its role and the role of parent coaching in reducing preoperative anxiety.
