Non-pharmacological Interventions for Preoperative Anxiety in Children: A Systematic Review and Network Meta-Analysis

AIMS

This study aimed to compare the efficacy of non-pharmacological interventions in children with preoperative anxiety.

BACKGROUND

It is estimated that preoperative anxiety affects up to 60% of children which is associated with both immediate and long-term adverse outcomes. Several non-pharmacological interventions have been demonstrated to be effective, but further research is necessary to determine which is the most effective.

DESIGN

This study was conducted and reported in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) 2020 checklist.

METHODS

We searched randomised controlled trials in twelve databases from which inception to March 31, 2024. The primary outcome was the severity of preoperative anxiety change from the baseline to the endpoint which is usually before the anaesthesia induction. Within the frequentist framework, a random-effects network meta-analysis (NMA) was used to compare the primary outcomes. The surface under the cumulative ranking curve (SUCRA) was used to rank each intervention separately. Subgroup and sensitivity analyses were carried out for the primary outcomes.

RESULTS

A total of 36 randomised controlled trials (RCTs) with 3182 paediatric patients were included. Based on the results, psychological + digital health intervention was significantly more effective than control groups and ranked highest. Combined parental presence during induction anaesthesia and video games (PPIA + VG) had significant benefits compared to almost all other interventions with the highest rank.

CONCLUSION

Psychological + digital health interventions, especially PPIA + VG, may be the most effective non-pharmacological interventions for reducing preoperative anxiety in children. It is necessary to conduct more RCTs to evaluate the efficacy of different non-pharmacological interventions.

RELEVANCE TO CLINICAL PRACTICE

Non-pharmacological interventions can effectively improve preoperative anxiety in children.

Effects of reading augmented reality storybook versus normal storybook reading on preoperative fear and anxiety levels of children in the age group of 7-12 years: A randomized controlled trial

AIM AND OBJECTIVES

In the preoperative period, non-pharmacological methods such as multimedia applications and visual and audio technological tools are used to reduce children's fear and anxiety levels and to distract their attention to create a more enjoyable experience. One of these innovative technologies having attracted attention recently is augmented reality technology. The study was aimed investigating the effects of reading an augmented reality storybook on fear and anxiety levels of children in the age group of 7-12 years in the preoperative period.

METHODS

The sample of the study consisted of 60 children who met the inclusion criteria. Of them, 30 were in the augmented reality story group, and 30 were in the normal story group. Data were collected through the following data collection tools: 'Sociodemographic Information Form', 'Children's Anxiety Meter' and 'Child Fear Scale'. The book "One Child, One Miracle" was used as an intervention tool in the study. The clinical trial registration number of this randomized controlled experimental study is NCT06399016.

RESULTS

In the study, a statistically significant difference and a decrease in the pre-test and post-test fear and anxiety average scores of the children in both groups was observed. The mean fear score of the children in the Augmented reality storybook reading group decreased more than did the score of the children in the normal story reading group.

CONCLUSIONS

In order to prevent preoperative fear and anxiety in children staying in pediatric surgery clinics, it is recommended to expand the use of augmented reality storybooks before surgery. Reading stories is an effective, inexpensive and non-pharmacological intervention.

3-Dimensional Virtual Reality Versus 2-Dimensional Video for Distraction During the Induction of Anesthesia in Children to Reduce Anxiety: A Randomized Controlled Trial

BACKGROUND

Preoperative anxiety is common in children. It can contribute to negative experiences with anesthetic induction and may cause adverse physiological and psychological effects. Virtual reality (VR) and electronic tablet devices are 2 audiovisual distraction tools that may help to reduce anxiety and enhance the preoperative experience. This study aimed to compare the use of an immersive 3-dimensional (3D) VR to 2-dimensional (2D) video on anxiety in children during induction of general anesthesia.

METHODS

Two hundred children (4-13 years) undergoing elective or emergency surgery under general anesthesia were enrolled in this randomized, controlled trial. Participants were randomized to use either the 3D VR goggles (intervention) or 2D video tablet (control) during anesthetic induction. Anxiety, the primary outcome, was measured using the modified Yale Preoperative Anxiety Scale Short Form (mYPAS-SF) at 2 time points: in the preoperative holding area before randomization (T1) and during induction of general anesthesia (T2). The primary outcome was analyzed using a linear regression model, including demographic and other covariates, to investigate any differences in anxiety scores. Secondary outcomes included evaluating compliance during the anesthetic induction (Induction Compliance Checklist), emergence of delirium (Cornell Assessment of Pediatric Delirium), perceived usefulness of the device, and child satisfaction.

RESULTS

Participant characteristics were similar between the 3D VR (n = 98) and 2D video (n = 90) groups, with a mean (±standard deviation) age 8. 8 ± 2.8 years. The median (lower quartile, upper quartile) mYPAS-SF scores for the 3D VR group at the preoperative holding area were 22.9 (22.9, 35.4), then 29.2 (24.0, 41.7) during induction. For the 2D Video group, the scores were 27.1 (22.9, 35.4) and then 30.2 (22.9, 41.1). No significant difference was observed in the increase in mYPAS-SF scores between groups (P = .672). Children in the 3D VR group were less likely to be rated as having a perfect induction (P = .039). There was no evidence of a difference between the groups in emergence delirium. Both devices were rated highly for usefulness and patient satisfaction. Children preferred VR, while anesthesiologists and parents felt the 2D was more useful.

CONCLUSIONS

This randomized controlled trial demonstrated that preoperative anxiety was equally low and induction compliance high with both 3D VR and 2D video distraction in children with parental presence during anesthetic induction.

Non-pharmacological interventions for preventing emergence delirium in children under general anesthesia: A scoping review

PROBLEM

The phenomenon of emergence delirium in pediatric patients undergoing general anesthesia has garnered increasing attention in the academic community. While formal non-pharmaceutical interventions have demonstrated efficacy in mitigating this phenomenon, the diversity of intervention types and their varying degrees of effectiveness necessitate further discussion. A scoping review was conducted to identify and explicate the categorization, content elements, and outcomes measures of non-pharmacological interventions utilized to forestall the onset of emergence delirium in children undergoing general anesthesia.

ELIGIBILITY CRITERIA

This review was conducted in accordance with the Arksey and O'Malley's methodology framework and PRISMA-ScR. It encompassed experimental and quasi-experimental studies that involved any non-pharmacological interventions during the perioperative period to prevent emergence delirium in children aged 0 to 18 years undergoing general anesthesia for elective surgery.

SAMPLE

Thirty-two articles met the inclusion criteria, of which 29 were randomized controlled trials. The total sample size of the population was 4633.

RESULTS

The scoping review revealed 10 non-pharmacological interventions, that included distraction intervention, visual preconditioning, virtual reality, parental participation, maternal voice, light drinking, acupuncture, auditory stimulation, monochromic light and breathing training. Emergence delirium, preoperative anxiety, and postoperative pain were the primary outcomes, and four assessment instruments were employed to measure the extent and incidence of emergence delirium.

CONCLUSION

Numerous non-pharmacological interventions have been employed to prevent emergence delirium. Nevertheless, the effectiveness of some interventions is not yet evident.

IMPLICATIONS

The utilization of visual preconditioning and distraction interventions appears to be an emerging area of interest.

A Systematic Review of Tablet-Based Interactive Distraction as a Preoperative Anxiolytic in Pediatric Patients Undergoing Same-Day Procedures

Evidence shows tablet-based interactive distraction (TBID) is effective as a preoperative anxiolytic in pediatric patients. TBID involves age-appropriate video games that have been preloaded onto a tablet (TAB) and subsequently given to a pediatric patient before the administration of anesthesia. The purpose of this study is to provide a comprehensive analysis of previous studies that have investigated the use of TBID to minimize preoperative anxiety. The literature criteria for this systematic review included randomized controlled trials and prospective studies that used TBID as a method to reduce preoperative anxiety in pediatric patients aged 1-12 years. Data extraction concentrated on the patient population to which the TABs were introduced, the method of TAB administration, how anxiety was evaluated, who completed the evaluations, and the results of each publication. This chosen data set is to systematically understand if TBID is effective and to identify the most practical ways to implement TBID. Collected data from the selected publications were entered into a table. For this systematic review, 27 publications from 2006 to 2023 were screened for eligibility. These studies were selected using a combination of MeSH terms and a Title-Abstract filter in PubMed, Embase, and Scopus. These data represented 475 total patients (T) and 249 patients who implemented TAB use. The other 226 patients were used as various control groups. The outcome of each study is summarized and placed into a table. This study is expected to provide an overall assessment of the effectiveness of TBID and proposed guidelines for clinicians to incorporate TAB use into preoperative protocols. The time to give the TAB to the children impacts its efficiency. This review accentuates the effectiveness of utilizing TBID to mitigate preoperative anxiety in pediatric patients based on a comprehensive analysis of multiple prior studies conducted in diverse healthcare settings, including pediatric hospitals and surgical centers. TAB use demonstrated an effective reduction in perioperative anxiety, emergence of delirium, and time to discharge, increasing parental satisfaction compared to midazolam. These results are likely replicable across a broader range of clinical settings, provided the intervention parameters, such as the timing of TAB introduction and the personalization of content to patient interests, are carefully adapted to each situation. The anxiety evaluations of patients using TBID varied based on the evaluator. Therefore, future research should analyze if perceived anxiety in patients using TABs is consistent or not among the evaluators. The impact of this TBID review has the potential to set a new benchmark for managing pediatric preoperative anxiety, with significant implications for healthcare quality and patient satisfaction.

Effect of a game-based intervention on preoperative pain and anxiety in children: A systematic review and meta-analysis

BACKGROUND

Games are increasingly being used as a means of alleviating pain and anxiety in paediatric patients, in the view that this form of distraction is effective, non-invasive and non-pharmacological.

AIMS

To determine whether a game-based intervention (via gamification or virtual reality) during the induction of anaesthesia reduces preoperative pain and anxiety in paediatric patients.

METHODS

A systematic review with meta-analysis of randomised controlled trials was performed in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and using RevMan software. The review was based on a search of the EMBASE, CINAHL, Medline, SciELO and Scopus databases, conducted in July 2021. No restriction was placed on the year of publication.

RESULTS

26 studies were found, with a total study population of 2525 children. Regarding pain reduction, no significant differences were reported. For anxiety during anaesthesia induction, however, a mean difference of -10.62 (95% CI -13.85, -7.39) on the Modified Yale Preoperative Anxiety Scale, in favour of game-based intervention, was recorded.

CONCLUSIONS

Game-based interventions alleviate preoperative anxiety during the induction of anaesthesia in children. This innovative and pleasurable approach can be helpful in the care of paediatric surgical patients.

RELEVANCE TO CLINICAL PRACTICE

In children, preoperative management is a challenging task for healthcare professionals, and game-based strategies could enhance results, improving patients' emotional health and boosting post-surgery recovery. Distractive games-based procedures should be considered for incorporation in the pre-surgery clinical workflow in order to optimise healthcare.

Overview and Strategy Analysis of Technology-Based Nonpharmacological Interventions for In-Hospital Delirium Prevention and Reduction: Systematic Scoping Review

BACKGROUND

Delirium prevention is crucial, especially in critically ill patients. Nonpharmacological multicomponent interventions for preventing delirium are increasingly recommended and technology-based interventions have been developed to support them. Despite the increasing number and diversity in technology-based interventions, there has been no systematic effort to create an overview of these interventions for in-hospital delirium prevention and reduction.

OBJECTIVE

This systematic scoping review was carried out to answer the following questions: (1) what are the technologies currently used in nonpharmacological technology-based interventions for preventing and reducing delirium? and (2) what are the strategies underlying these currently used technologies?

METHODS

A systematic search was conducted in Scopus and Embase between 2015 and 2020. A selection was made in line with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Studies were eligible if they contained any type of technology-based interventions and assessed delirium-/risk factor-related outcome measures in a hospital setting. Data extraction and quality assessment were performed using a predesigned data form.

RESULTS

A total of 31 studies were included and analyzed focusing on the types of technology and the strategies used in the interventions. Our review revealed 8 different technology types and 14 strategies that were categorized into the following 7 pathways: (1) restore circadian rhythm, (2) activate the body, (3) activate the mind, (4) induce relaxation, (5) provide a sense of security, (6) provide a sense of control, and (7) provide a sense of being connected. For all technology types, significant positive effects were found on either or both direct and indirect delirium outcomes. Several similarities were found across effective interventions: using a multicomponent approach or including components comforting the psychological needs of patients (eg, familiarity, distraction, soothing elements).

CONCLUSIONS

Technology-based interventions have a high potential when multidimensional needs of patients (eg, physical, cognitive, emotional) are incorporated. The 7 pathways pinpoint starting points for building more effective technology-based interventions. Opportunities were discussed for transforming the intensive care unit into a healing environment as a powerful tool to prevent delirium.

Virtual reality for pediatric periprocedural care

PURPOSE OF REVIEW

Commercial availability of virtual reality headsets and software has exponentially grown over the last decade as it has become more sophisticated, less expensive, and portable. Although primarily used by the general public for entertainment, virtual reality has been adopted by periprocedural clinicians to improve patient experiences and treatments. The purpose of this review is to explore recently reported evidence for virtual reality effectiveness for pediatric periprocedural care and discuss considerations for clinical implementation.

RECENT FINDINGS

In the preprocedure setting, practitioners use virtual reality to introduce children to periprocedural environments, distract attention from preprocedural vascular access, and increase cooperation with anesthesia induction. Intraprocedure, virtual reality decreases sedation requirements, and in some instances, eliminates anesthesia for minor procedures. Virtual reality also augments pain reduction therapies in the acute and extended rehabilitation periods, resulting in faster recovery and improved outcomes. Virtual reality seems to be well treated for pediatric use, given close clinical care and carefully curated content.

SUMMARY

Given the multiple clinical applications of virtual reality to supplement pediatric periprocedural care, practitioners should consider developing clinical programs that reliably provide access to virtual reality. Future research should focus on identification of patient characteristics and types of software that yield optimal patient outcomes.

Video Glasses Reduce Preoperative Anxiety Compared With Portable Multimedia Player in Children: A Randomized Controlled Trial

PURPOSE

Preoperative anxiety in children is challenging for anesthesia providers and nurses. The use of video glasses (VG), an immersive head mount display, helps conceal the unfamiliar operating room environment from the patient's visual field. The aim of this study was to determine the anxiolytic effect of VG compared with that of a portable multimedia player (PMP) during the preoperative period in children.

DESIGN

Prospective randomized trial.

METHODS

Participants were randomized into VG or PMP groups. Patients watched their favorite animation videos using the allocated device from the time of entering the preanesthetic holding area to the end of anesthetic induction. We evaluated modified Yale Preoperative Anxiety Scale scores during anesthetic induction.

FINDINGS

The modified Yale Preoperative Anxiety Scale score in the VG group was significantly lower than that in the PMP group (P = .001).

CONCLUSIONS

In children, the anxiolytic effect of VG during the preoperative period is larger than that of PMP.
