Virtual reality simulations to alleviate fear and anxiety in children awaiting MRI: a small-scale randomized controlled trial

Up to 75% of paediatric patients experience anxiety and distress before undergoing new medical procedures. Virtual reality is an interesting avenue for alleviating the stress and fear of paediatric patients due to its ability to completely immerse the child in the virtual world and thus expose them to the sights and sounds of an MRI before undergoing the exam. We aimed to explore the impact of virtual reality exposure on reducing fear and anxiety in paediatric patients scheduled to undergo an MRI. We hypothesised that patient who had undergone VR exposure before the MRI would experience lower levels of fear and anxiety and subsequently have a higher MRI success rate. We conducted a prospective randomized control trial in a tertiary paediatric hospital over three weeks. Inclusion criteria comprised children aged 4 to 14 undergoing MRI without medical contraindications for VR use. Thirty patients (16 in VR, 14 in control) were included in the study. The VR room, created in-house by a researcher, that the VR group experienced, simulated MRI room with typical sounds for up to 5 min before their actual MRI. Fear and anxiety were measured using the FACES scale before and after MRI for the control group as well as after VR exposure for the VR group. The VR group exhibited a significant reduction in anxiety post-VR exposure regarding the upcoming MRI (p = 0.009). There was no significant difference with regards to fear and anxiety between the VR and control groups before or after the MRI exam. There was no significant difference between the MRI exam success rates. VR exposure effectively reduces pre-MRI anxiety in paediatric patients who are about to undergo the exam, this is important as it alleviates the psychological burden on the child. This research is in line with previous findings, showing the validity of VR as a method of reducing pre-procedural paediatric anxiety and suggesting that complex VR experiences may not be necessary to have a significant impact. There is, however, a need for further investigation in this field using larger and MRI-naïve groups of patients.

Use of Biofeedback-Based Virtual Reality in Pediatric Perioperative and Postoperative Settings: Observational Study

BACKGROUND

Biofeedback-based virtual reality (VR-BF) is a novel, nonpharmacologic method for teaching patients how to control their breathing, which in turn increases heart rate variability (HRV) and may reduce pain. Unlike traditional forms of biofeedback, VR-BF is delivered through a gamified virtual reality environment, increasing the accessibility of biofeedback. This is the first study to systematically integrate VR-BF use in the pediatric perioperative setting, with the ultimate goal of evaluating the efficacy of VR-BF to reduce pain, anxiety, and opioid consumption once feasibility and acceptability have been established.

OBJECTIVES

The primary objective was to develop a clinical trial protocol for VR-BF use in the pediatric perioperative setting, including preoperative education and training, and postoperative application of VR-BF in children undergoing surgery. A secondary objective was to evaluate the patient and parent experience with VR-BF.

METHODS

A total of 23 patients (12-18 years of age) scheduled for surgery at Nationwide Children's Hospital were recruited using purposive sampling. Following training, participants independently completed a daily, 10-minute VR-BF session for 7 days before surgery and during their inpatient stay. Participants could use VR-BF up to 2 weeks after hospital discharge. Patient- and session-level data of VR-BF usage and achievement of target HRV parameters were measured to identify the optimal frequency and duration of sessions before and after surgery for this population. Standardized questionnaires and semistructured interviews were conducted to obtain qualitative information about patients' experiences with VR-BF.

RESULTS

Patient-level data indicated that the highest odds of achieving 1 session under target HRV parameters was after 4 sessions (odds ratio [OR] 5.1 for 4 vs 3 sessions, 95% CI 1.3-20.6; OR 16.6 for 3 vs 2 sessions, 95% CI 1.2-217.0). Session-level data showed that a session duration of 9 to 10 minutes provided the greatest odds of achieving 1 session under target HRV parameters (OR 1.3 for 9 vs 8 min, 95% CI 1.1-1.7; OR 1.4 for 8 vs 7 min, 95% CI 1.1-1.8; OR 1 for 10 vs 9 min, 95% CI 0.9-1.2). Qualitative data revealed patient satisfaction with the VR-BF technology, particularly in managing perioperative stress (17/20, 85%). Few patients reported VR-BF as beneficial for pain (8/20, 40%).

CONCLUSIONS

Children and adolescents undergoing surgery successfully learned behavioral strategies with VR-BF with 10-minute sessions once daily for 5 days. To integrate VR-BF as a therapeutic intervention in a subsequent clinical trial, patients will be instructed to complete three 10-minute sessions a day for 7 days after surgery.

How to use participatory design to develop an eHealth intervention to reduce preprocedural stress and anxiety among children visiting the hospital: The Hospital Hero app multi-study and pilot report

BACKGROUND

Medical procedures can cause considerable stress and anxiety among children. Current interventions mainly diminish stress and anxiety during procedures, while stress and anxiety often build up at home. Moreover, interventions often focus on either distraction or preparation. eHealth can combine multiple strategies and provide a low-cost solution that can be used outside the hospital.

OBJECTIVE

To develop an eHealth solution to diminish preprocedural stress and anxiety, and to evaluate the app on use, usability and user experience in practice. We also aimed to gain in-depth insights in children's and caregivers' opinions and experiences to inform future improvements.

METHODS

This is a multi-study report on the development (Study 1) and evaluation (Study 2) of a first version of the developed app. In study 1 we adopted a participatory design approach in which children's experiences were central to the design process. We performed an experience journey session with stakeholders (n = 13) to map the child's outpatient journey, identify pains and gains, and formulate the desired experience journey. Iterative development and testing with children (n = 8) and caregivers (n = 6) resulted in a working prototype. The prototype was tested with children, resulting in a first version of the Hospital Hero app. The app was evaluated on use, user-experience and usability during an eight-week pilot study in practice (Study 2). We triangulated data from online interviews with children and caregivers (n = 21) and online questionnaires (n = 46).

RESULTS

Multiple stress and anxiety experience touchpoints were identified. The Hospital Hero app supports children in their hospital journey by facilitating preparation at home and providing distraction at the hospital. The pilot study showed that the app was evaluated positively on usability and user-experience and is considered feasible. Qualitative data showed five themes: (1) user-friendliness, (2) coherence and power of storytelling, (3) motivation and reward, (4) fit with real hospital journey, (5) procedural comfort.

DISCUSSION

Using participatory design, we developed a child-centered solution that supports children in the entire hospital journey and may diminish preprocedural stress and anxiety. Future efforts should create a more tailored journey, define an optimal engagement window and formulate implementation strategies.

Heart Rate Variability Biofeedback in Cancer Patients: A Scoping Review

Heart Rate Variability (HRV) Biofeedback (BFB) has been shown to improve autonomic balance and wellbeing in chronic diseases. As cardiac variability represents an index of cognitive and emotional regulation, HRV-BFB has been shown to lead to improvements in physiological and psychological adaptability and quality of life. However, knowledge of HRV-BFB in cancer patients is lacking, and available results are diversified according to methods and outcomes. The present paper undertakes a scoping review, exploring the use of HRV-BFB to modulate autonomic balance, cancer symptom management, and quality of life in cancer. This scoping review analyzes empirical evidence considering study designs, BFB methods, and psychophysiological outcomes. Research that focused on HRV-BFB effects in cancer patients was selected (79%). In addition, a systematic review and meta-analysis (31%) focusing on HRV, or BFB in chronic conditions, including cancer, were considered. The studies examined BFB treatment for thyroid, lung, brain or colon cancer, hematologic cancer, and survivors or terminal cancer patients. Retrieved studies reported physiological and psychological indices as primary outcomes: they included HRV values, sleep, pain, fatigue, depression, anxiety, and quality of life. Although the heterogeneity of publications makes it difficult to generalize the effectiveness of HRV-BFB, the training has been proven to improve cancer symptoms and well-being.

The effects of a biofeedback and music training programme in reducing stress in Thai patients living with cancer receiving palliative care

BACKGROUND

Stress can physically effect patients with cancer undergoing palliative care and should be targeted for prevention.

AIM

To examine the effects of the biofeedback and music training programme (BMT programme) in decreasing stress among patients living with cancer receiving palliative care.

METHODS

A randomised controlled trial (RCT) repeated measure study was used to investigate the effects of the BMT programme.

FINDINGS

The participants in the BMT programme had the lowest mean stress recorded before, during and after the experiment, while the control group had a higher mean of stress in every measurement period. There were significant differences among groups across the time periods (Wilks' lambda =0.269, F=7.081, p<0.01).

CONCLUSION

Use of the BMT programme resulted in a significant reduction in patient stress. This confirms that the BMT programme plays an important role in helping patients living with cancer that experience high volumes of stress.

Is heart rate variability biofeedback useful in children and adolescents? A systematic review

BACKGROUND

Heart rate variability (HRV) is considered as an index of both physical and emotional health, and biofeedback aiming to increase the level of HRV has demonstrated extensive beneficial effects. Although HRV biofeedback is commonly and reliably applied in adults, the use of this technique, alone or in addition to other treatments, in children and adolescents has not been widely explored to date.

METHODS

This systematic review following PRISMA guidelines covers all human studies using HRV biofeedback in children and adolescents. A literature search was conducted in PsycINFO, PubMed and Scopus, and a standardized methodological quality assessment was performed.

RESULTS

Results showed the efficiency of HRV biofeedback sessions with children and adolescents to reduce physical and mental health-related symptoms and enhance well-being.

CONCLUSIONS

These findings underline the therapeutic value of using HRV biofeedback as a complement to more conventional behavioural and cognitive interventions to help children to manage stress and/or pain. Capitalizing on the identified strengths and shortcomings of available results, we propose research avenues as well as evidence-based clinical guidelines for using HRV biofeedback in clinical paediatric settings.

Non-drug Stress Management for Patients with Cancer: A Systematic Review

Background:

Patients with cancer suffer from the physical impacts of the disease, including pain in organs where cancer has spread to and treatment side effects. Many factors affect the mental state of cancer patients, especially stress which can cause muscle tension around the affected area and create a higher degree of pain. Stress impacts physical conditions and results in a worse quality of life. Thus, an appropriate approach to cope with, evaluate, and manage stress in cancer patients is considered crucial.

Objective:

The purpose of this systematic review was to determine and evaluate non-drug stress management guidelines for cancer patients.

Methods:

A systematic review was undertaken to synthesize knowledge concerning stress and non-drug stress management for cancer patients. Information was sourced from documents and articles published by related institutions in relevant electronic databases, including PubMed, PsycINFO, Dynamed, and ScienceDirect between 2013 and 2019. No limitations were imposed regarding the type of study design previously used. Conference abstracts were not accepted. The quality of all included studies was independently appraised by two review writers.

Results:

The search generated 129 studies, of which only 20 met the inclusion criteria. The 20 studies cover 11 studies of music for cancer prevention and 6 studies of mindfulness-based stress reduction in cancer patients. The studies utilized both quantitative and qualitative approaches, while three studies of biofeedback in cancer patients only collected quantitative data. For the outcome from the reviews, 6 studies found that music therapy, biofeedback, and mindfulness greatly impact physical alterations such as insomnia, nausea or vomiting, and pain. Furthermore, 17 studies found that non-drug management techniques had a positive impact on psychological adjustments such as stress and anxiety reduction and relaxation promotion. Non-drug stress management such as music, biofeedback, and mindfulness was found to reduce stress among patients.

Conclusion:

This review confirms that non-drug stress management approaches can reduce suffering, lead to a better quality of life, reduce mortality rates, minimize treatment costs, and prevent and mitigate unwanted symptoms in cancer patients. This approach can be adapted and applied to patients with other diseases in the future. However, because several of the reviewed studies did not have a follow-up period, the present study was unable to collect evidence suggesting how long the observed benefits will remain.

Targeted self-regulation interventions in low-income children: Clinical trial results and implications for health behavior change

Self-regulation, known as the ability to harness cognitive, emotional, and motivational resources to achieve goals, is hypothesized to contribute to health behaviors across the lifespan. Enhancing self-regulation early in life may increase positive health outcomes. During pre-adolescence, children assume increased autonomy in health behaviors (e.g., eating; physical activity), many of which involve self-regulation. This article presents results from a clinical trial (NCT03060863) that used a factorial design to test behavioral interventions designed to enhance self-regulation, specifically targeting executive functioning, emotion regulation, future-oriented thinking, and approach biases. Participants were 118 children (9-12 years of age, M = 10.2 years) who had a history of living in poverty. They were randomized to receive up to four interventions that were delivered via home visits. Self-regulation was assayed using behavioral tasks, observations, interviews, and parent- and child-report surveys. Results were that self-regulation targets were reliably assessed and that interventions were delivered with high fidelity. Intervention effect sizes were very small to moderate (d range = .02-.65, median = .14), and most were not statistically significant. Intercorrelation analyses indicated that associations between measures within each target varied based on the self-regulation target evaluated. Results are discussed with regard to the role of self-regulation-focused interventions in child health promotion. Implications of findings are reviewed for informing next steps in behavioral self-regulation interventions among children from low-income backgrounds.

Feasibility of Using a Single Heart Rate-Based Measure for Real-time Feedback in a Voluntary Deep Breathing App for Children: Data Collection and Algorithm Development

Background

Deep diaphragmatic breathing, also called belly breathing, is a popular behavioral intervention that helps children cope with anxiety, stress, and their experience of pain. Combining physiological monitoring with accessible mobile technology can motivate children to comply with this intervention through biofeedback and gaming. These innovative technologies have the potential to improve patient experience and compliance with strategies that reduce anxiety, change the experience of pain, and enhance self-regulation during distressing medical procedures.

Objective

The aim of this paper was to describe a simple biofeedback method for quantifying breathing compliance in a mobile smartphone app.

Methods

A smartphone app was developed that combined pulse oximetry with an animated protocol for paced deep breathing. We collected photoplethysmogram data during spontaneous and subsequently paced deep breathing in children. Two measures, synchronized respiratory sinus arrhythmia (RSA_sync) and the corresponding relative synchronized inspiration/expiration heart rate ratio (HR-I:E_sync), were extracted from the photoplethysmogram.

Results

Data collected from 80 children aged 5-17 years showed a positive RSA_sync effect in all participants during paced deep breathing, with a median (IQR; range) HR-I:E_sync ratio of 1.26 (1.16-1.35; 1.01-1.60) during paced deep breathing compared to 0.98 (0.96-1.02; 0.82-1.18) during spontaneous breathing (median difference 0.25, 95% CI 0.23-0.30; P<.001). The measured HR-I:E_sync values appeared to be independent of age.

Conclusions

An HR-I:E_sync level of 1.1 was identified as an age-independent threshold for programming the breathing pattern for optimal compliance in biofeedback.

Systematic Review of Biofeedback Interventions for Addressing Anxiety and Depression in Children and Adolescents with Long-Term Physical Conditions

Children and adolescents with long-term physical conditions are at increased risk of psychological problems, particularly anxiety and depression, and they have limited access to evidence-based treatment for these issues. Biofeedback interventions may be useful for treating symptoms of both psychological and physical conditions. A systematic review of studies of biofeedback interventions that addressed anxiety or depression in this population was undertaken via MEDLINE, EMBASE, PsycINFO, CINAHL and the Cochrane Central Register of Controlled Trials databases. Primary outcomes included changes in anxiety and depression symptoms and 'caseness'. Secondary outcomes included changes in symptoms of the associated physical condition and acceptability of the biofeedback intervention. Of 1876 identified citations, 9 studies (4 RCTs, 5 non-RCTs; of which all measured changes in anxiety and 3 of which measured changes in depression) were included in the final analysis and involved participants aged 8-25 years with a range of long-term physical conditions. Due to the heterogeneity of study design and reporting, risk of bias was judged as unclear for all studies and meta-analysis of findings was not undertaken. Within the identified sample, multiple modalities of biofeedback including heart rate variability (HRV), biofeedback assisted relaxation therapy and electroencephalography were found to be effective in reducing symptoms of anxiety. HRV was also found to be effective in reducing symptoms of depression in two studies. A range of modalities was effective in improving symptoms of long-term physical conditions. Two studies that assessed acceptability provided generally positive feedback. There is currently limited evidence to support the use of biofeedback interventions for addressing anxiety and depression in children and adolescents with long-term physical conditions. Although promising, further research using more stringent methodology and reporting is required before biofeedback interventions can be recommended for clinical use instead or in addition to existing evidence-based modalities of treatment.

Internalizing symptoms in AYA survivors of childhood cancer and matched comparisons

OBJECTIVE

As the number of pediatric cancer survivors increases, so does our need to understand behavioral late effects. Prior studies show mixed results, with some noting increased emotional distress and psychiatric diagnoses in cancer survivors and others suggesting resilience. The purpose of our study was to evaluate internalizing symptoms such as anxiety and depression in young adult survivors of childhood cancer compared with matched classroom matched peers.

METHOD

We completed a multisource, cross-sectional examination of internalizing symptoms using a semistructured psychiatric interview with 18-year-olds with a history of pediatric cancer compared with age, race, and gender matched classroom peers who had been identified during the survivor's first year of treatment and their primary caregivers.

RESULTS

Fifty-seven young adult survivors of childhood cancer and 60 comparison peers participated. There were no significant differences between survivors and their peers on the basis of self- or parent-reported depressive or anxiety symptoms or number of psychiatric diagnoses.

CONCLUSIONS

Young adult survivors of childhood cancer and their parents did not report increased rates of anxiety or depression compared with their former classroom peers. Despite experiencing a major life challenge, this group of young adults with cancer did not report more current or past symptoms of internalizing psychopathology.

Intervention Protocol: Technology-Based Psychosocial Motivation for Children with Cancer and Their Parents: A Randomized Trial

Objective:

This experimental randomized controlled trial will be to examine the impact of a technology-based psychosocial motivation program on children and families who are being followed up on a diagnosis of cancer.

Methods:

The research is based on the “Transactional Model of Stress and Coping.” This study will be conducted on children with leukemia, aged 9–18 years, and their parents, who will be followed in the consolidation treatment phase in the hematology wards and outpatient clinic of a university hospital. Data collection will consist of the children's and parents' descriptive characteristic form, the Spielberger State Anxiety Inventory for Parents, the State-Trait Anxiety Inventory for Children, the Pediatric Cancer Coping Scale, the Pediatric Quality of Life Inventory, and process evaluation forms. A 10-week program will be implemented for the children in the intervention group through web-based training, coaching interviews and counseling via video mobile calls, mobile messages and children's stories, progressive muscle relaxation and breathing exercises, and imagination interventions. During the same period, parents will also receive web-based training, coaching sessions, counseling, mobile messages, and progressive muscle relaxation exercises.

Results:

It is thought that after the intervention the stress level of the child and the family will decrease, the coping skills of the children will improve, and their quality of life will increase.

Conclusions:

It is thought that the treatment process can be affected positively by providing psychosocial support to children and their families who receive cancer treatment.

Creating authentic video scenarios for use in prehospital research

Video scenarios have been used to explore clinical reasoning during interviews in Think Aloud studies. This study used nominal group technique with experts to create video scenarios to explore the ways paramedics think and reason when caring for children who are sick or injured. At present there is little research regarding paramedics' clinical reasoning with respect to performing non-urgent procedures on children. A core expert panel identified the central structure of a prehospital clinical interaction and the range of contextual factors that may influence a paramedic's clinical reasoning [the way in which information is gathered, interpreted and analysed by clinicians]. The structure and contextual factors were then incorporated into two filmed scenarios. A second panel of clinical practice experts, then critiqued the body language, spoken word and age appropriate behaviours of those acting in the video scenarios and compared them against their own experience of clinical practice to confirm authenticity. This paper reports and reflects on the use of nominal group technique to create authentic video scenarios for use in prehospital research.

Mind-Body Therapies in Children and Youth

Mind-body therapies are popular and are ranked among the top 10 complementary and integrative medicine practices reportedly used by adults and children in the 2007-2012 National Health Interview Survey. A growing body of evidence supports the effectiveness and safety of mind-body therapies in pediatrics. This clinical report outlines popular mind-body therapies for children and youth and examines the best-available evidence for a variety of mind-body therapies and practices, including biofeedback, clinical hypnosis, guided imagery, meditation, and yoga. The report is intended to help health care professionals guide their patients to nonpharmacologic approaches to improve concentration, help decrease pain, control discomfort, or ease anxiety.

Procedural Preparation and Support as a Standard of Care in Pediatric Oncology

Youth with cancer undergo many repeated and invasive medical procedures that are often painful and highly distressing. A systematic review of published research since 1995 identified 65 papers (11 review articles and 54 empirical studies) that investigated preparatory information and psychological interventions for a variety of medical procedures in pediatric cancer. Distraction, combined cognitive-behavioral strategies, and hypnosis were identified as effective for reducing child pain and increasing child coping. Low- to high-quality evidence informed strong recommendations for all youth with cancer to receive developmentally appropriate preparatory information and psychological intervention for invasive medical procedures.
