Decreasing Pain and Fear in Medical Procedures with a Pediatric Population (DREAM): A Pilot Randomized Within-Subject Trial

Extended Reality (XR) in Pediatric Acute and Chronic Pain: Systematic Review and Evidence Gap Map

BACKGROUND

The use of extended reality (XR), including virtual reality (VR) and augmented reality (AR), for treating pain has accelerated in the last 10 years. XR is an attractive biobehavioral intervention that may support management of pain or pain-related disability. Reviews of the literature pertaining to adults report promising results, particularly for acute procedural pain.

OBJECTIVE

This study aimed to (1) summarize the available evidence with respect to feasibility, safety, and effectiveness (pain intensity) of XR for pediatric acute and chronic pain; (2) summarize assessment tools used to measure study outcomes; and (3) identify gaps in evidence to guide future research efforts.

METHODS

This study is a systematic review of the literature. Multiple databases (CINAHL, Cochrane Central, Embase, MEDLINE, PsycINFO) were searched from inception until March 2023. Titles, abstracts, and full-text articles were reviewed by 2 team members to determine eligibility. Articles were included if the (1) participants were aged 0 to 18 years; (2) study intervention was VR or AR; (3) study outcomes included safety, feasibility, acceptability, or effectiveness on the outcome of pain; and (4) study design was observational or interventional. Data were collected on bibliographic information; study characteristics; XR characteristics; outcome domains; outcome measures; and study findings pertaining to safety, feasibility, and effectiveness.

RESULTS

We included 90 articles in the review. All included studies used VR, and 93% (84/90) studied VR in the context of acute pain. Of the 90 studies, 74 studies were randomized trials, and 15 studies were observational. Safety was assessed in 23 studies of acute pain, with 13 studies reporting no adverse events and 10 studies reporting events of low concern. Feasibility was assessed in 27 studies. Of the 84 studies of acute pain, 62% (52/84) reported a positive effect on pain intensity, 21% (18/84) reported no effect, and 13% (11/84) reported mixed effects. All 6 studies of chronic pain reported a positive effect on pain intensity. An evidence gap map was used to illuminate gaps in specific research areas stratified by subtypes of pain. Risk of bias assessment revealed 67 studies had a moderate risk of bias, 17 studies had a high risk, and 5 studies were deemed to be low risk.

CONCLUSIONS

The current body of literature around XR for pediatric pain is focused on acute pain with promising results of safety and effectiveness on pain intensity. The literature pertaining to chronic pain lags behind, limiting our ability to draw conclusions. The risk of bias in studies is problematic in this field, with the inherent challenge of blinding participants and researchers to the intervention. Future research should aim to measure effectiveness beyond pain intensity with a consistent approach to measuring key outcome domains and measures. Current efforts are underway to establish expert consensus on best research practices in this field.

Effectiveness of Virtual Reality for Managing Pain, Fear, and Anxiety in Children and Adolescents Undergoing Needle-Related Procedures: Systematic Review with Meta-Analysis

The most frequently performed invasive procedures in hospitals and healthcare centers are needle-related procedures, such as intravenous cannulation and phlebotomy, and they are identified as the major sources of pain, fear, and anxiety in children and adolescents. The objective of this systematic review was to evaluate the effectiveness of VR as a distraction measure to reduce pain, fear, and anxiety in children and adolescents undergoing needle-related invasive procedures. For this purpose, the CINAHL, Scopus, WOS, and Cochrane Library scientific databases were used. The protocol review was registered in PROSPERO (ID:42024563245), and inclusion and exclusion criteria were applied. Twenty-one studies were included in the systematic review, involving a total of 2663 participants. Significant differences favored the use of virtual reality for the control of pain intensity (WBFSpatients p = 0.001; MD = -1.83; 95% CI -2.93 to -0.72; WBFSparents p = 0.0002; MD = -2.61; 95% CI -4.00 to -1.23; WBFSnurses p = 0.0001; MD = -2.71; 95% CI -2.82 to -2.60; VAS/NRS p = 0.001, MD = -0.71; 95% CI -1.13 to -0.28), anxiety (CAMpatient p = 0.02, MD = -2.92; 95% CI -5.45 to -0.38; CAMparents p = 0.01, MD = -3.87; 95% CI -6.99 to -0.75) and fear (CFSpatients p = 0.0005, MD = -1.27; 95% CI -1.99 to -0.56; CFSparents p = 0.0005, MD = -1.33; 95% CI -2.08 to -0.58; and CFSnurses p = 0.04, MD = -1.13; 95% CI -2.24 to -0.03). However, high heterogeneity was noted. The use of virtual reality as a distraction appears to be a valuable strategy for reducing pain, fear, and anxiety during needle-related procedures, although further studies with higher methodological rigor, based on a standardized protocol, are needed.

Technology and Children's health: Effect of virtual reality on pain and clinical outcomes during hydrotherapy for children with burns

BACKGROUND

Virtual Reality (VR) has been frequently used as an engaging, interactive, and effective non-pharmacological distraction technique for children during painful procedures, including burnt wound care.

AIM

This study aimed to evaluate the effect of virtual reality on pain and clinical outcomes during hydrotherapy for children with burns.

DESIGN

A randomized controlled pretest, during, and post-test research design was utilized.

METHODS

Sixty children with burns underwent hydrotherapy, divided randomly and assigned equally into two groups. Children of the control group received the standard pharmacological treatment of the unit to manage pain and stabilize their physiological parameters throughout the three days of study. Children of the virtual reality intervention group received all basic standard care as the control group plus VR intervention across different software content, and interaction immersion designs which took place using a cell phone coupled with the three-dimensional (3D) image glasses. Outcome measures were physiological parameters, wound healing, and Face, Leg, Activity, Cry and Consolability (FLACC) Behavioral Pain Assessment Scale.

SETTING

This study was carried out in the burns unit at the Plastic, Reconstructive, and Burns Surgery Center affiliated to Mansoura University, from September to November 2023.

RESULTS

Children in the study group had lower pain scores, more stable physiological parameters, and higher rates of wound healing compared to the control group with a statistically significant difference between both groups.

CONCLUSION

Using VR intervention significantly reduced pain intensity, enhanced physiological parameters and promoted the rate of wound healing in children with burns during hydrotherapy.

The Effect of Using Virtual Reality During Burn Dressing on Pain, Anxiety and Fear Felt in Children: A Randomized Controlled Trial

This study was conducted to determine the effect of using virtual reality (VR) during burn dressing on the level of fear, anxiety, and pain that children would experience. This randomized controlled trial was conducted in a pretest-posttest design. Randomization of the participants (n = 65) was performed with the block randomization method. Then, 33 children were included in the intervention and 32 children in the control group with simple sequential randomization. The study data were collected using the "Family and Child Personal Information Form," "Physiological Parameters Registration Form," "Wong-Baker Faces Pain Scale," "Children's Fear Scale," and "Children's Anxiety Meter-State." The chi-square test, t-test, Shapiro-Wilk, mean, and percentile distributions were used for the data analysis. After dressing, the physiological parameters of the children who used VR were found to be within normal limits (HR: 108.48 ± 12.43, O2: 98.39 ± 1.14) compared to the children who did not use (HR: 117.38 ± 15.25, O2: 97.81 ± 1.35) (P < .05). After the dressing, children using VR (0.85 ± 1.23) were determined to have less fear than those who did not use them (3.03 ± 1.06), and similarly, children who used VR (2.64 ± 2.73) experienced less anxiety than those who did not use them (5.84 ± 2.26). When the pain levels were evaluated, the VR group (1.79 ± 2.04) was reported to feel less pain compared to the control group (5.50 ± 2.36). The VR used by children aged 5-10 years during burn dressing has been found to affect their physiological parameters and is effective in reducing fear, anxiety, and pain levels.

Comparing novel virtual reality and nursing standard care on burn wound care pain in adolescents: A randomized controlled trial

PURPOSE

This study compared the effectiveness of age-appropriate, high technology, interactive virtual reality (VR) distraction with standard care (SC) provided by the nurse on adolescents' acute procedural pain intensity perception during burn wound care treatment in the ambulatory clinic setting.

DESIGN

This randomized controlled trial included 43 adolescents ages 10-21 from the ambulatory burn clinic of a large children's hospital.

METHODS

Blinded study participants were randomly assigned to either VR or SC (non-significantly different, current mean burn surface area, 1.3 and 1.7, respectively) during the first burn wound care procedure in the burn clinic. Blinded research staff collected pre-procedure data including Spielberger's State-Trait Anxiety Inventory and postprocedure wound care pain intensity using the Adolescent Pediatric Pain Tool. A total of 41 participants completed all study procedures.

RESULTS

No statistically significant difference in burn wound care procedural pain was noted between the VR and SC groups after adjusting for several factors. Pre-procedure state and trait anxiety correlated with reported pre-procedure pain. Wound care pain was found to be significantly associated with pre-wound care pain score, time from original burn to clinic burn care treatment, and length of wound care treatment. These factors accounted for approximately 45% of the variation in pain scores during wound care treatment.

PRACTICE IMPLICATIONS

VR distraction can be a useful pain management strategy but may not take the place of the unique nurse-patient relationship that occurs during clinical encounters. Tailoring pain management during burn wound care requires consideration of anxiety, time from the burn injury to the wound care procedure, length of time of the wound care procedure, and pretreatment pain level. Knowing patients' needs, desires, and temperaments along with the specifics about the healthcare procedures are critical to formulating individualized care plans that may or may not include VR. Newer technology, such as easier-to-use, less expensive VR, may assist with translation into practice making its clinical use more routine.

The effect of visual and/or auditory distraction techniques on children's pain, anxiety and medical fear in invasive procedures: A randomized controlled trial

PURPOSE

This study was conducted to determine the effects of visual and/or auditory distraction techniques applied to children aged 7-12 during invasive procedures on pain, anxiety, and medical fear.

METHODS

This single-blinded, randomized controlled trial was carried out in the pediatric emergency department of a public hospital between November 2021 and March 2022. In the study, 144 children were assigned to three different intervention groups, in which a kaleidoscope, music, and virtual reality were applied during invasive procedures, and the control group in which the standard invasive procedure was applied, by using the stratified block randomization method. The data were collected using a Personal Information Form, Wong-Baker Faces Pain Rating Scale, Children's Anxiety Meter-State, and Child Medical Fear Scale.

RESULTS

In the study, the levels of pain, anxiety, and medical fear after the invasive procedure were lower in the intervention groups than in the control group. In addition, there was no difference between the three different distraction techniques in terms of reducing pain and medical fear, but the virtual reality application was more effective in reducing the level of anxiety.

CONCLUSION

Visual and/or auditory distraction techniques are effective methods that can be used by nurses in pediatric healthcare to reduce invasive procedure-related pain, anxiety, and medical fear.

IMPLICATIONS FOR PRACTICE

This study provides evidence that can guide the use of non-pharmacological methods such as distraction to prevent the traumatic effects of invasive procedures in children.

Effectiveness of virtual reality intervention on reducing the pain, anxiety and fear of needle-related procedures in paediatric patients: A systematic review and meta-analysis

AIMS

To evaluate the effectiveness of virtual reality (VR) intervention in the management of pain, anxiety and fear in paediatric patients undergoing needle-related procedures.

DESIGN

A systematic review and meta-analysis of randomized controlled trials (RCTs).

DATA SOURCES

A librarian-designed search of the Cochrane Library, PubMed, Web of Science, EMBASE, CINAHL, CBM, CNKI, and Wanfang databases was conducted to identify research articles in English or Chinese on RCTs up to February 28, 2022.

REVIEW METHODS

Two researchers independently screened eligible articles. The Cochrane Handbook for Systematic Reviews was used to assess the risk of bias in the included studies. A fixed- or random-effects meta-analysis model was used to determine the pooled mean difference based on the results of the heterogeneity test.

RESULTS

A total of 2269 articles were initially screened. The meta-analysis included data from 27 studies representing 2224 participants. Compared with the non-VR group, the VR intervention group significantly reduced pain, anxiety, and fear in paediatric patients who underwent puncture-related procedures. Subgroup analysis showed that VR has advantages over conventional and other distraction methods.

CONCLUSION

Paediatric patients undergoing needle-related procedures would benefit from VR interventions for pain, anxiety and fear management.

IMPACT

VR intervention has the potential to reduce pain, anxiety and fear in paediatric patients undergoing puncture-related procedures. Future clinical interventions could incorporate VR into puncture procedures as an effective method to reduce negative emotions in children eligible for VR distractions.

Virtual reality mobility for burn patients (VR-MOBILE): A within-subject-controlled trial protocol

In the acute phase, burn patients undergo several painful procedures. Pediatric burn care procedures conducted in hydrotherapy have been known to generate severe pain intensity and moderate to high levels of anxiety. Hydrotherapy treatments are done with the use of opioids and benzodiazepines for pain and anxiety. Unfortunately, nonpharmacological methods are rarely combined with pharmacological treatments despite evidence showing that distraction can serve as an effective method for pain management and can potentially decrease analgesic requirements in other painful medical procedures. Virtual reality (VR) is a method that uses distraction to interact within a virtual environment. The use of VR is promising for pain reduction in varying settings. Considering the lack of optimal pain and anxiety management during burn wound care and the positive effect of an immersive distraction for painful procedures, using VR for burn wound care procedures may show promising results. This is a within-subject randomized controlled trial design in which each participant will serve as his/her own control. A minimum of 20 participants, aged 7 to 17 years old undergoing a burn care session, will receive both standard and experimental treatments during the same session in a randomized order. The experimental treatment will consist of combining VR distraction using the video game Dreamland® to the current standard pharmacological care as per unit protocol. The control group will only receive the unit's standard pharmacological care. The mean difference in both pain intensity scores and in anxiety between the two different sequences will be the primary outcomes of this study. This study evaluates the effect of VR on burn wound care. If results from this study show a positive effect of VR compared to standard care, this protocol may provide guidance on how to implement this type of immersive care as part of the tools available for distraction of painful procedures for acute burn victims.

Effect of immersive virtual reality on pain in different dental procedures in children: A pilot study

BACKGROUND

Implementing effective pain management is important to increase patient compliance during paediatric dental procedures.

AIM

This pilot study was conducted to evaluate the effectiveness of virtual reality (VR) on pain perception in dental procedures in children.

MATERIAL AND METHODS

Fifty-four children aged between 5 and 12 years were included. Patients scheduled to receive dental procedures not requiring local anesthesia (eg, fluoride therapy) were assigned to Group A, and patients scheduled to receive painful dental procedures requiring local anesthesia (eg, pulp therapy, teeth extraction) were assigned to Group B. Patients in each group were randomly assigned and were equally likely to either receive VR during their dental procedure, or treatment as usual (without VR). Visual analog scale (VAS), Wong-Baker FACES rating scale, and the 'Face, Legs, Activity, Cry, Consolability' scale (FLACC scale) were used to assess the pain levels during dental procedures.

RESULTS

Patients receiving painful dental procedures requiring local anesthesia reported significant reductions in pain intensity/worst pain during the dental procedure on all subjective and behavioral pain measures of pain intensity with the use of VR distraction technique (P < .05 on each). Patients receiving non-painful dental procedures showed the predicted pattern but no significant reduction in worst pain during VR.

CONCLUSION

The use of VR was found to be an effective distraction tool to ease pain and anxiety in the tested dental procedures, for children receiving painful dental procedures.

Impact of Virtual Reality Technology on Pain and Anxiety in Pediatric Burn Patients: A Systematic Review and Meta-Analysis

INTRODUCTION

Virtual reality (VR) has the potential to lessen pain and anxiety experienced by pediatric patients undergoing burn wound care procedures. Population-specific variables require novel technological application and thus, a systematic review among studies on its impact is warranted.

OBJECTIVE

The objective of this review was to evaluate the effectiveness of VR on pain in children with burn injuries undergoing wound care procedures.

METHODS

A systematic literature review was performed using PubMed and CINAHL databases from January 2010 to July 2021 with the keywords "pediatric," "burn," "virtual reality," and "pain." We included experimental studies of between- and within-subjects designs in which pediatric patients' exposure to virtual reality technology during burn wound care functioned as the intervention of interest. Two researchers independently performed the literature search, made judgements of inclusion/exclusion based on agreed-upon criteria, abstracted data, and assessed quality of evidence using a standardized appraisal tool. A meta-analysis was conducted to evaluate the effectiveness of the VR on burning procedural pain in pediatric population. Standardized mean difference (SMD) was used as an index of combined effect size, and a random effect model was used for meta-analysis.

RESULTS

Ten articles published between January 2010 and July 2021 passed the selection criteria: six randomized controlled trials and four randomized repeated-measures studies. Consistent results among the studies provided support for VR as effective in reducing pain and potentially pain related anxiety in children undergoing burn wound care through preprocedural preparation (n = 2) and procedural intervention (n = 8). VR effects on pain intensity ratings were moderate to large (SMD=0.60, 95%CI=0.28-0.93, p=0.0037 with no significant heterogeneity of VR intervention effects between studies. Only one study reported direct influence of VR intervention on pre-procedural situational anxiety with a moderate effect size (Cohen's d = 0.575, 95%CI = 0.11-1.04).

CONCLUSION

Children's exposure to VR during burn care procedures was associated with lower levels of pain and pain related anxiety. Moderate to large effect sizes support the integration of VR into traditional pediatric burn pain protocols irrespective of innovative delivery methods and content required for use in burned pediatric patients.

The Effect of Virtual Reality Game Preparation for Children scheduled for MRI (IMAGINE): a Randomized Controlled Trial Protocol (Preprint)

Background

It is known that magnetic resonance imaging (MRI) procedures generate fear and anxiety. Children may become restless during scanning, which results in movement artifacts requiring the MRI procedure to be repeated with sedation. Few studies seem to have looked at the effect of immersive virtual reality (IVR) on anxiety in children scheduled for MRI scans and how to identify which children are more responsive.

Objective

The aims of this study are 3-fold: develop an algorithm of predictability based on biofeedback, address feasibility and acceptability of preprocedural IVR game preparation for anxiety management during MRI procedures, and examine the efficacy of IVR game preparation compared with usual care for the management of procedural anxiety during MRI scans.

Methods

This study will have 2 phases. We will first conduct a field test with 10 participants aged 7 to 17 years to develop a predictive algorithm for biofeedback solution and to address the feasibility and acceptability of the research. After the field test, a randomized controlled trial will be completed using a parallel design with 2 groups: an experimental group (preprocedural IVR game preparation) and a usual care group (standard care as per the radiology department’s protocol) in an equal ratio of 49 participants per group for 98 participants. Recruitment will be carried out at a hospital in Quebec, Canada. The experimental group will receive a preprocedural IVR game preparation (IMAGINE) that offers an immersive simulation of the MRI scan. Participants will complete a questionnaire to assess the acceptability, feasibility, and incidence of side effects related to the intervention and the biofeedback device. Data collected will include sociodemographic and clinical characteristics as well as measures of procedure-related anxiety with the French-Canadian version of the State-Trait Anxiety Inventory for Children (score 1-3) and the Children’s Fear Scale (score 0-4). Physiological signs will be noted and include heart rate, skin conductance, hand temperature, and muscle tension. Measures of the level of satisfaction of health care professionals, parents, and participants will also be collected. Analyses will be carried out according to the intention-to-treat principle, with a Cronbach α significance level of .05.

Results

As of May 10, 2022, no participant was enrolled in the clinical trial. The data collection time frame is projected to be between April 1, 2022, and March 31, 2023. Findings will be disseminated through peer-reviewed publications.

Conclusions

Our study provides an alternative method for anxiety management to better prepare patients for an awake MRI procedure. The biofeedback will help predict which children are more responsive to this type of intervention. This study will guide future medical practice by providing evidence-based knowledge on a nonpharmacological therapeutic modality for anxiety management in children scheduled for an MRI scan.
