Effects of Preoperative Virtual Reality Magnetic Resonance Imaging on Preoperative Anxiety in Patients Undergoing Arthroscopic Knee Surgery: A Randomized Controlled Study

Development and Effectiveness Evaluation of 360-Degree Virtual Reality-Based Educational Intervention for Adult Patients Undergoing Colonoscopy

Providing patients with accurate and organized information about colonoscopy, while reducing anxiety, is critical to the procedure's success. This study evaluated the impact of an immersive 360° virtual reality (VR)-based educational intervention for first-time adult colonoscopy patients regarding anxiety, attitudes, knowledge, compliance with bowel preparation, and bowel cleanliness. A quasi-experimental design with a non-equivalent control group and non-synchronized pretest-post-test clinical trial was conducted with 40 patients in the experimental group and 40 in the control group. The 360° VR intervention included two sessions: precautions before colonoscopy and the colonoscopy process. The control group received education through individual verbal explanations with written materials. The findings indicated that the VR intervention significantly improved patients' colonoscopy-related anxiety, attitudes, adherence to bowel preparation instructions, and bowel cleanliness. Utilizing 360° VR as an educational tool has the potential to enhance the effectiveness of educational programs by providing realistic information and engaging patients. These findings suggest that 360° VR has the capacity to enhance screening rates and clinical outcomes by reducing negative perceptions associated with colonoscopy. Furthermore, the application of this method can extend to diverse diagnostic testing-related nursing situations in clinical settings.

SAFEvR MentalVeRse.app: Development of a Free Immersive Virtual Reality Exposure Therapy for Acrophobia and Claustrophobia

Background: Specific phobias impact over 400 million people worldwide. Digitalizing mental health could alleviate the burden. Still, although the corporate-driven Metaverse is expanding rapidly, there needs to be more momentum in harnessing virtual reality exposure therapy uptake. Objective: This study aims to conceptualize, develop, and deploy a free Virtual Reality Exposure Therapy (VRET) application specifically designed for treating acrophobia and claustrophobia. This pilot study, which holds the promise of a future where mental health is more accessible and effective, explores the feasibility of leveraging transdisciplinary collaboration among specialists to create a safe, accessible, and effective VRET solution. Methods: We conducted a Delphi heuristic approach involving bioethicists, neuroscientists, and tech developers. Second, we reviewed the existing psychological theories and therapeutic strategies for addressing phobias in VR. Third, we conceptualized a thematic analysis-derived framework for a safe, adaptive-gamified free exposure to virtual reality acrophobia and claustrophobia (SAFEvR ACT). Finally, we provide an overview of the iterative improvements made during 12 workshops and 76 weekly briefings on developmental implementations. Results: We developed the SAFEvR ACT into a proof-of-concept application freely deployed on the MentalVerse app platform. Our safety-focused approach can benefit from prevalidation perspectives within future randomized control trials. Conclusions: The resulting application derived from the SAFEvR ACT framework represents a blueprint to counter the current lack of iVR mental health uptake by offering a free VRET alternative. Future research should aim towards developing similar free platforms to lessen mental health burdens and gather quantitative data. We conclude with a call to action to researchers to fine-tune our current approach and take a stand for free digital mental health within MentalVeRse.app.

Virtual reality exposure reduce acute postoperative pain in female patients undergoing laparoscopic gynecology surgery: A Randomized Control Trial (RCT) study

STUDY OBJECTIVE

Few studies have focused on the effect of virtual reality (VR) exposure on postoperative acute pain in adult female patients undergoing gynecology surgery.

DESIGN

A randomized control trial (RCT) study.

SETTING

At Beijing Fuxing Hospital.

PATIENTS

115 patients aged between 20 and 60 years, American Society of Anesthesiologists (ASA) physical status I - II were consecutively enrolled and randomly divided into VR group (n = 58) or control group (n = 57).

INTERVENTIONS

Patients in the VR group received 15 min of VR video viewing before surgery.

MEASUREMENTS

The primary outcome was acute postoperative pain at 8 h which was measured by the Visual Analogue Scale (VAS) scores. The secondary outcomes including the use of analgesic drugs, the incidence of moderate pain and postoperative recovery which were recorded 24 h after surgery. The Hospital Anxiety and Depression Scale (HADS) was also used to evaluate patients' emotional status before surgery.

MAIN RESULTS

The VAS scores at 30 min [2 (1,2) vs. 3 (2,3)], 2 h [2 (2,3) vs. 4 (3,4)], 4 h [3 (2,4) vs. 4 (4,5)], 8 h [3 (2,4) vs. 4 (4,5)], 12 h [2 (2,3) vs. 4 (3,4)], 24 h [1 (1,2) vs. 3 (2,3)] after surgery. Generalized estimation equation (GEE) indicated that VR intervention was negatively correlated with postoperative VAS values (β = -0.830, S.E = 0.199, 95%CI (-1.220,-0.439), Wald χ2 = 17.359, p<0.05), in the meanwhile, VR also lower the incidence of moderate pain (VAS > 4) at 8 h postoperatively (12.1% vs 31.0%, p = 0.013). However, the 24 h tramadol usage remained unchanged. Patients in the VR group had better sleep quality (6.33 ± 2.3 vs. 4.12 ± 2.5, p < 0.001) and lower incidence of nausea (43.1% vs. 63.2%, p < 0.05), dizziness (0% vs. 14.0%, p < 0.05), and headache (12.1% vs. 29.8%, p < 0.05). VR could reduce the median HADS scores (9.81 ± 6.1 vs 3.14 ± 3.9, p < 0.001) and blood pressure preoperatively.

CONCLUSIONS

VR intervention can reduce acute postoperative pain with better postoperative recovery and lower preoperative anxiety level in adult female patients undergoing laparoscopic gynecology surgery.

Impact of virtual reality education on disease-specific knowledge and anxiety for hepatocellular carcinoma patient scheduled for liver resection: a randomized controlled study

PURPOSE

Hepatocellular carcinoma (HCC) is a significant health concern, and the complexity of liver anatomy poses challenges in conveying radiologic findings and surgical plans to patients. This study aimed to evaluate the impact of a virtual reality (VR) education program on anxiety and knowledge in HCC patients undergoing hepatic resection.

METHOD

From 1 January 2022 to 28 February 2023, 88 patients were enrolled in a randomized controlled trial, divided into the VR group ( n =44) and the control group ( n =44). The VR group received patient-specific 3D liver model education through a VR platform, while the control group underwent conventional explanation processes. Both groups completed preintervention and postintervention questionnaires assessing anxiety (using STAI-X-1, STAI-X-2, and VAS) and knowledge about liver resection. Comparison of the questionnaires were performed between the two groups. Multivariable logistic regression was performed to analyze factor related to decrease in anxiety.

RESULT

While there was no significant difference in preintervention anxiety and knowledge scores between the two groups, the VR group exhibited significant reduction in STAI-X-1 scores (-4.14±7.5) compared to the control group (-0.84±5.7, P =0.023), as well as knowledge scores (17.20±2.6) compared to the control group (13.42±3.3, P <0.001). In the multivariable logistic regression model, VR education showed significant impact on decrease in STAI-X-1 score, postintervention. (OR=2.902, CI=1.097-7.674, P =0.032).

CONCLUSION

The VR education program significantly improved knowledge and reduced anxiety among HCC patients compared to conventional methods. This study suggests that VR can be a valuable tool in patient education, enhancing comprehension and alleviating presurgical anxiety.

BACKGROUND

The integration of virtual reality (VR) in surgery has gained prominence as VR applications have increased in popularity.

METHODS

A scoping review was undertaken, gathering the most relevant sources, utilising a detailed literature search of medical and academic databases including EMBASE, PubMed, Cochrane, IEEE, Google Scholar, and the Google search engine.

RESULTS

Of the 18 articles included, 7 focused on VR in colon surgery, 5 addressed VR in pancreas surgery, and the remaining 6 concentrated on VR in liver surgery. All the articles concluded that VR has a promising future in abdominal surgery by facilitating precision, visualisation, and surgeon training.

CONCLUSIONS

Adopting VR technology in abdominal surgery has the potential to improve preoperative planning, decrease perioperative anxiety among patients, and facilitate the training of surgeons, residents, and medical students. Additional supporting studies are necessary before VR can be widely implemented in surgical care delivery.

Surgery-related anxiety regarding arthroscopic meniscectomy under general anesthesia: a retrospective observational study

BACKGROUND

The prevalence of anxiety among patients undergoing arthroscopic surgery and its association with postoperative function has been well documented; however, the level of anxiety and anxiety-related characteristics remain unclear. As such, the present study investigated the characteristics of state anxiety in patients undergoing arthroscopic meniscectomy.

METHODS

Data from 75 patients, who underwent arthroscopic partial meniscectomy under general anesthesia and completed an anxiety status questionnaire between April 2021 and March 2022, were retrospectively collected and reviewed. The State-Trait Anxiety Inventory (STAI)-X was used to measure state anxiety; a total score ≥ 52 was defined as clinically meaningful state anxiety. STAI score, main cause of preoperative anxiety, most anxious period, and most helpful factors for reducing perioperative anxiety were investigated. Patients were divided into 2 groups according to the main cause of preoperative anxiety; surgery or anesthesia (group I [n = 47]); and postoperative pain or rehabilitation (group II [n = 28]) Characteristics of state-anxiety between the two groups were compared using independent t-tests.

RESULTS

The mean STAI score of the total population was 39.1 points (range, 20-60 points). The mean STAI score was significantly higher in group I than in group II (41.9 vs. 34.4 points, respectively; P < 0.001). The proportion of patients with clinically meaningful state anxiety was significantly higher in group I than in group II (23.4% vs. 3.6%, respectively, P = 0.02). Most patients (66.0% in group I and 50.0% in group II) responded that trust in medical staff was the most helpful factor in overcoming preoperative anxiety. In group I, 63.8% reported that the surgeon's explanation was the most helpful factor in reducing postoperative anxiety, whereas in group II, 71.4% reported that the natural course after surgery was the most helpful factor.

CONCLUSIONS

Surgeons should be aware that anxiety related to arthroscopic meniscectomy differs according to patient characteristics, and a preoperative explanation of the postoperative process with the surgeon is important for patients who experience preoperative anxiety regarding anesthesia or the surgery itself.

Advanced imaging and modeling in neonatal simulation

Advances in modeling and imaging have resulted in realistic tools that can be applied to education and training, and even direct patient care. These include point-of-care ultrasound (POCUS), 3-dimensional and digital anatomic modeling, and extended reality. These technologies have been used for the preparation of complex patient care through simulation-based clinical rehearsals, direct patient care such as the creation of patient devices and implants, and for simulation-based education and training for health professionals, patients and families. In this section, we discuss these emerging technologies and describe how they can be utilized to improve patient care.

Virtual Reality-Based Intervention to Reduce Preoperative Anxiety in Adults Undergoing Elective Surgery: A Randomized Clinical Trial

IMPORTANCE

Preoperative anxiety is common among adult patients undergoing elective surgery and is associated with negative outcomes. Virtual reality (VR)-based interventions have been considered simpler, safer, and more effective for reducing anxiety in patients undergoing surgery than conventional care.

OBJECTIVE

To examine the effectiveness of a VR-based intervention with preoperative education in reducing preoperative anxiety among adult patients undergoing elective surgery.

DESIGN, SETTING, AND PARTICIPANTS

An assessor-blinded prospective randomized clinical trial was conducted to recruit adult patients aged 18 years or older who were scheduled for their first elective surgery procedure under general anesthesia within the next 2 to 4 weeks at a preanesthesia assessment clinic in Hong Kong from July to December 2022.

INTERVENTIONS

Participants were randomly assigned to either an intervention group (an 8-minute immersive 360° VR video tour in the operating theater via a head-mounted display console) or a control group (standard care).

MAIN OUTCOMES AND MEASURES

The primary outcome of preoperative anxiety was measured using the Amsterdam Preoperative Anxiety and Information Scale (range, 6-30; higher scores indicate greater anxiety), and the secondary outcomes (ie, stress, preparedness, and pain) were assessed by Visual Analog Scale at 3 time points: baseline at beginning of clinical session (T0), at the end of the clinical session immediately after the intervention (T1), and before the surgery (T2). Pain, satisfaction levels, and postoperative length of stay were evaluated after the surgery (T3). Simulation sickness was assessed after the intervention by use of the Simulation Sickness Questionnaire. A generalized estimating equations model was applied to compare changes in outcomes over time.

RESULTS

A total of 74 participants (mean [SD] age, 46.34 [14.52] years; 38 men [51.4%] and 36 women [48.6%]) were recruited and randomized to the control group (37 participants) and intervention group (37 participants). Compared with the control group, the VR-based intervention group showed significantly decreased preoperative anxiety at T1 (β, -5.46; 95% CI, -7.60 to -3.32; P < .001) and T2 (β, -5.57; 95% CI, -7.73 to -3.41; P < .001), lower stress at T1 (β, -10.68; 95% CI, -16.00 to -5.36; P < .001) and T2 (β, -5.16; 95% CI, -9.87 to -0.45; P = .03), and higher preparedness at T1 (β, 6.60; 95% CI, 0.97 to 12.19; P = .02). Satisfaction levels were significantly increased in the intervention group vs the control group (mean [SD] score, 81.35 [9.24] vs 65.28 [8.16]; difference, 16.07; 95% CI, 12.00 to 20.15; P < .001). No significant differences in pain and postoperative length of stay were found.

CONCLUSIONS AND RELEVANCE

The findings of this study suggest that a VR-based intervention is a feasible and effective way to reduce preoperative anxiety in adult patients undergoing elective surgery. Given the promising results of this study, further study in the form of large-scale, multicenter, randomized clinical trials with broader implementation is warranted.

A new dimension in medical education: Virtual reality in anatomy during COVID-19 pandemic

Virtual reality technology has been increasingly used in the field of anatomy education, particularly in response to the COVID-19 pandemic. Virtual reality in anatomy (VRA) allows the creation of immersive, three-dimensional environments or experiences that can interact in a seemingly real or physical way. A comprehensive search of electronic databases was conducted to identify relevant studies. The search included studies published between 2020 and June 2023. The use of VRA education has been shown to be effective in improving students' understanding and retention of knowledge, as well as developing practical skills such as surgical techniques. VRA can allow students to visualize and interact with complex structures and systems in a way that is not possible with traditional methods. It can also provide a safe and ethical alternative to cadavers, which may be in short supply or have access restrictions. Additionally, VRA can be used to create customized learning experiences, allowing students to focus on specific areas of anatomy or to repeat certain exercises as needed. However, there are also limitations to the use of VRA education, including cost and the need for specialized equipment and training, as well as concerns about the realism and accuracy of VRA models. To fully utilize the potential of VRA education, it is important for educators to carefully consider the appropriate use of VR and to continuously evaluate its effectiveness. It is important for educators to carefully consider the appropriate use of VRA and to continuously evaluate its effectiveness to fully utilize its potential.

Effectiveness of virtual reality in reducing preoperative anxiety in adults: A systematic review and meta-analysis

AIM

To evaluate the impact of a virtual reality (VR) intervention on adult patients' preoperative anxiety, heart rate, respiration rate and blood pressure.

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 studies in English or Chinese on RCTs from their inception to 31 May 2022. Detailed search strategies and the checklist are provieded in Supplementary files S1 and S2.

REVIEW METHODS

Two researchers independently screened eligible studies. The Cochrane Handbook for Systematic Reviews of Interventions 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

This study included 11 articles with a total of 892 participants. VR distraction comprised five studies, and VR exposure consisted of six studies. The results indicated that VR could reduce preoperative anxiety in adult patients and VR exposure seems to be more effective. The results also indicated that VR intervention can effectively reduce patients' heart rate and blood pressure compared to traditional intervention methods, but had no significant effect on respiration rate.

CONCLUSION

VR technology could relieve preoperative anxiety in adult patients through distraction or exposure. More well-designed RCTs containing a wider range of surgical types are needed to verify our findings before we can make strong recommendations.

IMPACT

Our systematic review and meta-analysis show a positive effect of VR distraction and exposure interventions in reducing preoperative anxiety in adult patients. We suggest incorporating VR into preoperative procedures as an auxiliary way to reduce negative emotions in eligible patients.

Sensory stimulations potentializing digital therapeutics pain control

For the past two decades, using Digital Therapeutics (DTx) to counter painful symptoms has emerged as a novel pain relief strategy. Several studies report that DTx significantly diminish pain while compensating for the limitations of pharmacological analgesics (e.g., addiction, side effects). Virtual reality (VR) is a major component of the most effective DTx for pain reduction. Notably, various stimuli (e.g., auditory, visual) appear to be frequently associated with VR in DTx. This review aims to compare the hypoalgesic power of specific stimuli with or without a VR environment. First, this review will briefly describe VR technology and known elements related to its hypoalgesic effect. Second, it will non-exhaustively list various stimuli known to have a hypoalgesic effect on pain independent of the immersive environment. Finally, this review will focus on studies that investigate a possible potentialized effect on pain reduction of these stimuli in a VR environment.

Using Virtual Reality to Reduce Anxiety and Improve Hospital Experience in Paediatric Orthopaedic Patients and Their Parents

The hospital environment can be a stressful environment for paediatric patients and their parents, which is often characterised by heightened levels of pain and anxiety. To address these challenges, many innovative intervention methods has been explored. For example, immersive virtual reality (VR) headsets as a distraction method has become an increasingly popular intervention in recent years. This study aimed to evaluate the effectiveness of VR using 'Rescape DR.VR Junior' in reducing pain, anxiety, and enhancing the overall hospital experience for paediatric orthopaedic patients and their parents. A total of 64 patients aged 4-18 years were included in this study, which utilised a control group (interacting with a play specialist) and a VR intervention group (including pre-operative patients and fracture clinic patients). Anxiety and pain levels were measured using a 10-point Likert scale before and after the intervention, and validated questionnaires were used to assess parental anxiety and overall hospital experience. The results indicated that VR intervention significantly reduced patient and parental anxiety both before surgery and in the fracture clinic setting (p < 0.5). However, no significant reduction in pain scores was observed in either environments. Comparatively, VR intervention was found to be comparable to traditional play methods in terms of reducing anxiety in the pre-operative environment. All patients and parents agreed that the use of VR distraction methods significantly improved their hospital experience. In conclusion, VR is an effective method for reducing child and parental anxiety and enhancing the hospital experience and can be used alone or in conjunction with a play specialist.

Effects of virtual reality on preoperative anxiety in children: A systematic review and meta-analysis of randomised controlled trials

AIMS

To synthesise and evaluate the effectiveness of virtual reality interventions in preoperative children.

BACKGROUND

Children consider operations as a predictable threat and stressful event. Children's anxiety before an operation increases as the time draws closer. Children could understand the operating room environment and process before the operation using virtual reality, which may reduce their anxiety before an operation.

DESIGN

A systematic review and meta-analysis of randomised controlled trials following the Cochrane method were conducted.

METHOD

CINAHL, Cochrane Library, Embase, Joanna Briggs Institute, MEDLINE and PubMed databases were searched for randomised controlled trials published before February 2021. A random-effects model meta-analysis to calculate pooled prevalence and 95% confidence intervals was performed. Conduction of the review adheres to the PRISMA checklist.

RESULTS

Of 257 articles screened, six interventions involving 529 participants aged 4-12 years were included in the analysis. All study evidence levels were B2/Level 2, the quality was medium to high on the modified Jadad scale, with a low risk of bias. The results revealed that virtual reality significantly reduced preoperative anxiety in children (SMD: -0.91, 95% CI: -1.43 to -0.39, p = .0006). Furthermore, virtual reality significantly improved children's compliance with anaesthesia (SMD: 3.49, 95% CI: 1.32 to 9.21, p = .01).

CONCLUSION

Children who used virtual reality before an operation felt more familiar with the operating room environment and understood the preoperative preparation procedures. Virtual reality effectively reduced children's anxiety and improved their compliance with anaesthesia.

RELEVANCE TO CLINICAL PRACTICE

This systematic review and meta-analysis investigated the effect of virtual reality on preoperative anxiety in children and the findings supported its positive effects. The results could provide a reference for incorporating virtual reality into preoperative preparation guidelines.

The Effects of Virtual Reality on Preoperative Anxiety in Patients Undergoing Colorectal and Abdominal Wall Surgery: A Randomized Controlled Trial

PURPOSE

The purpose of this study was to investigate the effects of a virtual reality (VR) application on preoperative anxiety (PA) in patients undergoing colorectal and abdominal wall surgery.

DESIGN

A prospective, parallel two-armed, randomized controlled trial.

METHODS

Eighty six patients were divided into the control group (n = 43) and in the experimental group (n = 43). The experimental group received a preoperative VR application for 10 minutes. The routine preoperative procedure used at the clinic was used for the patients in the control group. The anxiety level was assessed using the Anxiety Specific to Surgery Questionnaire (ASSQ) and measured with physiological responses to anxiety, such as changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), respiratory rate (RR), and peripheral oxygen saturation (SpO₂), before and after the VR application.

FINDINGS

The VR application reduced PA levels in the experimental group (P < .001) and changes in the SBP (P < .001), DBP (P < .001), HR (P < .001), RR (P = .041) and SpO₂(P = .019) values) compared to the levels in the control group.

CONCLUSIONS

VR applications can reduce psychological and physiological responses to PA in patients undergoing colorectal and abdominal wall surgery.

"Mixed Reality" in patient education prior to abdominal aortic aneurysm repair

Background: To investigate the usability of Mixed-Reality (MR) during patient education in patients scheduled for abdominal aortic aneurysm (AAA) repair. Patients and methods: Consecutive patients scheduled for elective AAA repair were block-randomized in either the Mixed-Reality group (MR group) or the conventional group (control group). Patients of both groups were educated about open and endovascular repair of their respective AAA. The MR group was educated using a head-mounted display (HMD) demonstrating a three-dimensional virtual reconstruction of the respective patient's vascular anatomy. The control group was educated using a conventional two-dimensional monitor to display the patient's vasculature. Outcomes were informational gain as well as patient satisfaction with the educational process. (DRKS-ID: DRKS00025174). Results: 50 patients were included with 25 patients in either group. Both groups demonstrated improvements in scores in the Informational Gain Questionnaire (IGQ) when comparing pre- and post-education scores. (MR group: 6.5 points (±1.8) versus 7.9 points (±1.5); Control group: 6.2 points (±1.8) versus 7.6 points (±1.6); p<0.01) There was no significant difference between the MR group and the control group either in informational gain (MR group: 1.4±1.8; Control group: 1.4±1.8; p=0.5) nor in patient satisfaction scores (MR group: mean 18.3 of maximum 21 points (±3.7); Control group: mean 17 of 21 points (±3.6); p=0.1) Multiple regression revealed no correlation between the use of MR and informational gain or patient satisfaction. Usability of the system was rated high, and patients' subjective assessment of MR was positive. Conclusions: The use of MR in patient education of AAA patients scheduled for elective repair is feasible. While patients reported positively on the use of MR in education, similar levels of informational gain and patient satisfaction can be achieved with MR and conventional methods.

The effectiveness of using virtual reality technology for perioperative anxiety among adults undergoing elective surgery: a randomised controlled trial protocol

BACKGROUND

More than 2.5 million people are admitted for surgery in Australia each year, and between 40 to 80% will experience moderate to high preoperative anxiety. Elevated levels of preoperative anxiety can increase the risk of postoperative complications such as pain, delayed wound healing, infection, prolonged recovery, and longer hospitalisation. Limited previous research on Virtual Reality (VR) indicates a positive impact on surgery-related anxiety and suggests that the intervention potentially leads to reduce postoperative complications.

OBJECTIVE

To evaluate the effectiveness of using VR technology for perioperative anxiety among adults undergoing elective surgery.

METHOD

A two-group parallel randomised controlled trial (RCT) will be conducted, including 150 adult patients (aged 18 years and over) undergoing elective surgery and requiring an overnight stay at a major metropolitan hospital. Eligible participants will be screened for anxiety via the Amsterdam Preoperative Anxiety and Information score (APAIS). Those with moderate to severe anxiety will be randomly allocated to receive the VR session or usual care, in the preoperative holding area. Intervention participants will use a head-mounted VR device to watch and listen to a nature scene for 10 minutes.

STUDY OUTCOMES

The primary outcome is perioperative anxiety measured using the visual analogue scale for anxiety (VAS-A). Secondary outcomes include stress levels (measured by saliva cortisol level and heart rate), postoperative pain, patient satisfaction with perioperative care, hospital length of stay, and VR-associated adverse events.

CONCLUSION

This study will help evaluate if a brief preoperative VR session can reduce perioperative anxiety for adult elective surgical patients.

Patients' voices in the development of pre-surgical patient education using virtual reality: A qualitative study

Objective

To identify the information needs and perceptions of patients regarding the application of virtual reality in pre-surgical patient education.

Methods

A qualitative study was conducted between March and July 2020. The study population consisted of a purposive sample of patients scheduled for cardiac surgery from a single institution. Semi-structured individual interviews (n=19) were conducted and analysed using thematic analysis.

Results

Patient perceptions regarding virtual reality and information needs related to hospitalisation and surgery could be categorised into three themes: Creating familiarity, contents to explore and challenges and preconditions.

Conclusions

Virtual reality technology is a promising tool that can enhance conventional patient education to improve understanding and to potentially reduce concerns and anxieties. The virtual reality environment creates an opportunity for patients to be in control of the timing, quantity, depth and frequency of patient education. A virtual reality education tool should not be a substitute for personal contact with the physician.

Innovation

Patient information needs were identified profoundly to the further development of a virtual reality intervention. This intervention aims to educate patients prior to elective cardiac surgery.

The use of virtual reality in patient education related to medical somatic treatment: A scoping review

OBJECTIVE

To map the available evidence on the context, content and outcome of VR in patient education in situations related to preparation for medical somatic treatment.

METHODS

A Scoping review. In October 2020, the Embase, CINAHL, MEDLINE and PsycINFO databases were searched with the terms 'Virtual Reality' and 'Patient Education'. The literature was synthesised and mapped with a narrative approach.

RESULTS

17 studies published between 2015 and 2020 were included in the qualitative synthesis. VR was applied in (paediatric) surgery and radiation therapy treatment. VR interventions were heterogeneous regarding technical applications, context of implementation, guidance by healthcare professionals and integration in education sessions. Anxiety reduction was demonstrated significantly in some studies. Patients experienced VR education useful; it enhanced understanding, improved communication with healthcare professionals and encouraged treatment compliance.

CONCLUSIONS

The application of VR in patient education is a promising technology. Patients are highly satisfied and experience enhanced understanding. VR education was not effective in reducing all anxiety, pain and stress and improving preparedness for treatment. Practice implications It is important to develop VR interventions profoundly. The application of a methodological framework for VR development is recommended. Involve patients, educationalists and technology professionals in the development of technology interventions.

State-of-the-Art Review on Immersive Virtual Reality Interventions for Colonoscopy-Induced Anxiety and Pain

BACKGROUND

Colonoscopy related fear impairs the current gold standard screening of colorectal cancer. Compared to other minimally invasive procedures for cancer screening, colonoscopy-induced anxiety exceeds the procedure through bowel preparation. Immersive virtual reality's (iVR) role in alleviating the complex stress-pain relationship encountered during medical procedures is directly proportional to the rising affordability of state-of-the-art Head-Mounted-Displays (HMDs).

OBJECTIVE

to assess the effect of iVR on patients' colonoscopy-induced anxiety and pain.

MATERIALS AND METHODS

A systematic search was conducted in PubMed, Cochrane Central Register of Controlled Trials, Web of Science, Embase and Scopus databases up to January 2022. Clinical trials evaluating anxiety as an outcome were included without language restriction.

RESULTS

Four clinical trials were included: three on the patients' intraprocedural anxiety and one on patient education. Intraprocedural iVR interventions for colonoscopy-induced anxiety and pain revealed a similar effect as conventional sedation, while a statistically significant reduction was reported for non-sedated patients. iVR patient education improved the quality of bowel preparation and reduced patient anxiety before colonoscopy.

CONCLUSIONS

The current research highlights the need to use high-end HMDs and appropriate interactive iVR software content for colonoscopy-induced anxiety. Methodological frameworks regarding the eligibility of participants, double-blinding and randomization of iVR studies can facilitate the development of iVR implementation for anxiety and pain management.

The current and possible future role of 3D modelling within oesophagogastric surgery: a scoping review

BACKGROUND

3D reconstruction technology could revolutionise medicine. Within surgery, 3D reconstruction has a growing role in operative planning and procedures, surgical education and training as well as patient engagement. Whilst virtual and 3D printed models are already used in many surgical specialities, oesophagogastric surgery has been slow in their adoption. Therefore, the authors undertook a scoping review to clarify the current and future roles of 3D modelling in oesophagogastric surgery, highlighting gaps in the literature and implications for future research.

METHODS

A scoping review protocol was developed using a comprehensive search strategy based on internationally accepted guidelines and tailored for key databases (MEDLINE, Embase, Elsevier Scopus and ISI Web of Science). This is available through the Open Science Framework (osf.io/ta789) and was published in a peer-reviewed journal. Included studies underwent screening and full text review before inclusion. A thematic analysis was performed using pre-determined overarching themes: (i) surgical training and education, (ii) patient education and engagement, and (iii) operative planning and surgical practice. Where applicable, subthemes were generated.

RESULTS

A total of 56 papers were included. Most research was low-grade with 88% (n = 49) of publications at or below level III evidence. No randomised control trials or systematic reviews were found. Most literature (86%, n = 48) explored 3D reconstruction within operative planning. These were divided into subthemes of pre-operative (77%, n = 43) and intra-operative guidance (9%, n = 5). Few papers reported on surgical training and education (14%, n = 8), and were evenly subcategorised into virtual reality simulation (7%, n = 4) and anatomical teaching (7%, n = 4). No studies utilising 3D modelling for patient engagement and education were found.

CONCLUSION

The use of 3D reconstruction is in its infancy in oesophagogastric surgery. The quality of evidence is low and key themes, such as patient engagement and education, remain unexplored. Without high quality research evaluating the application and benefits of 3D modelling, oesophagogastric surgery may be left behind.

Comparison of a Cryopneumatic Compression Device and Ice Packs for Cryotherapy Following Anterior Cruciate Ligament Reconstruction

Background

The purpose of the current study was to evaluate and compare the effectiveness of a cryopneumatic compression device with that of standard ice packs following arthroscopic anterior cruciate ligament (ACL) reconstruction, with a primary focus on early postoperative pain.

Methods

Participants were divided into two groups: cryopneumatic compression device group (CC group) and standard ice pack group (IP group). Patients in the CC Group (28 patients) received a cryopneumatic compression device (CTC-7, Daesung Maref) treatment, while patients in the IP group (28 patients) received standard ice pack cryotherapy postoperatively. All cryotherapy was applied three times (every 8 hours) per day for 20 minutes until discharge (postoperative day 7). Pain scores were assessed preoperatively and at 4, 7, and 14 days after surgery, and the primary outcome for analysis was pain at postoperative day 4 assessed using a visual analog scale (VAS). Other variables were opioid and rescue medication use, knee and thigh circumferences, postoperative drainage, and joint effusion quantified by a three-dimensional magnetic resonance imaging (MRI) reconstruction model.

Results

The mean pain VAS score and difference in VAS relative to the preoperative measurements for postoperative day 4 were significantly lower in the CC group than in the IP group (p = 0.001 and p = 0.007, respectively). The sum of postoperative drainage and effusion quantified by MRI showed a significant reduction of postoperative effusion in the CC group compared to the IP group (p = 0.015). The average total rescue medication consumption was comparable between the two groups. Circumferential measurements at days 7 and 14 postoperatively relative to those at day 4 (index day) demonstrated no significant differences between the groups.

Conclusions

Compared to standard ice packs, application of cryopneumatic compression was associated with a significant reduction in VAS pain scores and joint effusion during the early postoperative period following ACL reconstruction.

Intraoperative virtual reality distraction in TKA under spinal anesthesia: a preliminary study

INTRODUCTION

The effect of patient anxiety during the perioperative period has been shown to be of great importance in its influence on post-operative recovery. Over the last 10 years, virtual reality (VR) has been developed in anesthesia for patient's distraction by immersion. The aim of this study was to evaluate post-operative patient anxiety the day after TKA surgery under spinal anesthesia (SA) with or without VR distraction.

MATERIALS AND METHODS

A single-center, prospective cohort study was performed looking at patients undergoing TKA surgery under SA with a VR headset (group 1) compared with those undergoing the same procedure with standard protocol (group 2). Data using a validated scoring system looking at patient anxiety (STAI Y-1) were collected. Secondary endpoints were need for sedation during surgery, intraoperative complications (hypotension and oxygen need), postoperative pain and comfort scores (VAS) and patient satisfaction.

RESULTS

Ten patients (group 1) received the VR headset during surgery and 10 (group 2) received the standard protocol established in our center. Average age was 73 years old. No difference was found in post-operative patient anxiety regarding to STAI Y-1 score (95% CI - 7 to 10, p = 0.71. There was a decrease of sedation and intra-operative adverse event as hypotension and oxygen requirement in group 1 (p < 0.0001, p = 0.015, p = 0.0054), and a significant increase in comfort score (p = 0.002). No difference in patient satisfaction was found.

CONCLUSION

Using VR for immersive distraction seemed to lead to no difference in patient anxiety in TKA under SA. Intra-operative adverse events were decreased, and post-operative comfort was increased. Patient satisfaction was not modified. This preliminary study is encouraging and gives us arguments to involve larger number of patients while exploring the various possibilities offered by VR.

Review of Digitalized Patient Education in Cardiology: A Future Ahead?

INTRODUCTION

An increased focus on shared decision-making and patient empowerment in cardiology and on patient outcomes such as quality of life (QoL), depression, and anxiety underline the importance of high-quality patient education. Studies focusing on digital means of patient education performed in other disciplines of medicine demonstrated its positive effect in these areas. Therefore, a review of the current literature was performed to (i) evaluate the status of innovative, digitalized means of patient education in cardiology and (ii) assess the impact of digital patient education on outcome parameters (i.e., patient knowledge (or health literacy), QoL, depression, anxiety, and patient satisfaction).

METHOD

A review of the current literature was performed to evaluate the effect of digitalized patient education for any purpose in the field of cardiology. Medline and EMBASE were searched for articles reporting any digital educational platform used for patient education up to May 2020. The articles were compared on their effect on patient knowledge or health literacy, QoL, depression or anxiety, and patient satisfaction.

RESULTS

The initial search yielded 279 articles, 34 of which were retained after applying in, and exclusion criteria. After full-text analysis, the total number of articles remaining was 16. Of these, 6 articles discussed the use of smartphone or tablet applications as a means of patient education, whereas 3 reviewed web-based content, and 7 evaluated the use of video (2 three-dimensional videos, from which one on a virtual reality headset).

CONCLUSION

This review demonstrates that digital patient education increases patient knowledge. Overall, digital education increases QoL and lowers feelings of depression and anxiety. The majority of patients express satisfaction with digital platforms. It remains important that developers of digital patient education platforms remain focused on clear, structured, and comprehensible information presentation.

Effects of virtual reality on relieving postoperative pain in surgical patients: A systematic review and meta-analysis

BACKGROUND

Postoperative pain is a prevalent problem leading to many adverse outcomes in surgical patients. Virtual reality (VR) is an emerging non-pharmacological method of postoperative pain relief, but the effects of it are not clear. This review aimed to explore the effects of VR on relieving postoperative pain.

METHODS

Studies published up to November 2019 were identified by searching the PubMed (Medline), Embase, Web of Science, and other databases. Meta-analyses were conducted to compare VR and usual care for relieving postoperative pain. Subgroup analyses and sensitivity analyses were performed to explain the heterogeneity.

RESULTS

Overall, 8 randomized control trials (RCTs) enrolling 723 participants were included. Our results demonstrated that the patients receiving the VR intervention had lower postoperative pain scores than those receiving the usual care (mean difference [MD] -0.64; 95% CI -1.05 to -0.22; P = 0.002). One subgroup analysis revealed that VR could relieve postoperative pain both in minor surgery (MD -1.48; 95% CI -2.02 to -0.95; P < 0.0001) and major surgery (MD -0.32; 95% CI -0.53 to -0.11; P < 0.03). Another subgroup analysis demonstrated a significant reduction in postoperative pain among patients receiving VR during the intraoperative (MD -1.51; 95% CI -2.04 to -0.97; P < 0.00001) and the postoperative periods (MD -0.50; 95% CI -0.76 to -0.24; P = 0.002). However, there was no significant postoperative pain relief when receiving VR during the preoperative period. Additionally, significant improvements in postoperative satisfaction were reported in two studies. However, another two studies included found that VR could not affect physiological parameters related to pain.

CONCLUSIONS

Applying VR can relieve postoperative pain effectively. The type of surgery and timing of using VR are the main sources of heterogeneity. More rigorous studies about the relationship between VR and postoperative pain relief will be needed.

The Effect of Virtual Reality on Preoperative Anxiety: A Meta-Analysis of Randomized Controlled Trials

Virtual reality (VR), a technology that provides a stimulated sensory experience, has recently been implemented in various fields of medicine. Several studies have investigated the efficacy of VR on preoperative anxiety. The purpose of this meta-analysis was to validate whether VR could relieve preoperative anxiety in patients undergoing surgery. Electronic databases were searched to identify all randomized controlled trials (RCTs) investigating the effect of VR on preoperative anxiety. The primary outcome was defined as the preoperative anxiety scores. We estimated the effect size using the standard mean difference (SMD) with a 95% confidence interval (CI) using a random effect model. Ultimately, 10 RCTs, with a total of 813 patients, were included in the final analysis. Preoperative anxiety was significantly lower in the VR group than in the control group (SMD −0.64, 95% CI −1.08 to −0.20, p = 0.004). In a subgroup analysis, the preoperative anxiety scores were lower in the VR group than in the control group in pediatric patients (SMD −0.71, 95% CI −1.14 to −0.27, p = 0.002), whereas a significant difference was not observed between the two groups in adult patients (p = 0.226). The results of this meta-analysis indicated that VR could decrease preoperative anxiety, especially in pediatric patients.
