Abstract
BACKGROUND Preoperative anxiety (PA) is common in children and has detrimental effects on surgical outcome. Strategies based on virtual reality (VR) have recently been introduced to address this problem. OBJECTIVE This study evaluated the usefulness of a virtual reality educational program (VREP) for reducing preoperative anxiety in elective low-complexity paediatric surgery. DESIGN Randomised clinical trial. SETTING Single tertiary centre in Barcelona, Spain. Between January 2019 and June 2022. PATIENTS Children aged 3-13 years of age, American Society of Anesthesiologists (ASA) I-II, scheduled for elective low-complexity surgery were enrolled in the study. INTERVENTION Children were randomised into a control group (received oral/written information about the anaesthetic-surgical process, and patients and their parents remained in a playroom waiting for the surgery) or VREP (viewed a VR-based educational video on the surgical process, 7-10 days prior to surgery) using the MATLAB application. MAIN OUTCOME MEASURE PA using the modified Yale Preoperative Anxiety Scale (mYPAS) during separation from parents. RESULTS In total, 241 children aged 3-12 years of age were studied (120 patients with VREP and 121 controls). Randomisation eliminated the differences between the groups, except for a greater male presence in the VREP group (83.3% vs. 71.1%; P = 0.023). The mYPAS yielded was lower in the VREP group (29.2% vs. 83.5%; P < 0.001). Sex did not influence VREP-mediated decrease in PA ( P < 0.001). In turn, VREP patients were more cooperative (Induction Compliance Checklist [ICC] score 0 points vs. 2 points; P < 0.001) during anaesthesia induction, presented less delirium (Pediatric Anesthesia Emergence Delirium [PAED] score 1 point vs. 3 points; P = 0.001) on leaving the recovery room, and experienced less pain upon arrival in the hospital ward (Wong-Baker Faces Pain Rating Scale: 0-points vs. 1 point; P < 0.001). CONCLUSIONS The VREP-based prevention strategy reduced preoperative anxiety in children undergoing elective low-complexity surgery. TRIAL REGISTRATION NCT03578393.

Abstract
PROBLEM Virtual reality (VR) is used as a novel intervention technique to alleviate uncomfortable experiences such as anxiety and pain in children. Recently, VR distraction has gained prominence in pediatric medical procedures. However, no studies have yet conducted a further quantitative analysis of the intervention effects of virtual reality exposure (VRE). This systematic review aims to analyse the effect of VRE on anxiety and pain levels in paediatric patients undergoing medical procedures. ELIGIBILITY CRITERIA Relevant studies were searched from four databases, including PubMed, Cochrane Library, Embase, and Web of Science. This systematic review has been registered in the International Prospective Register of Systematic Reviews (PROSPERO). RESULTS The meta-analysis incorporated a total of 11 articles, encompassing 1,099 pediatric patients. The results showed that VRE relieved children's anxiety [SMD = -0.61, 95% CI (-0.93, -0.28), p < 0.001], but there was no significant difference in alleviating pain in children [SMD = -1.48, 95% CI (-3.40, 0.44), p = 0.131]. CONCLUSIONS The results suggest that VRE is effective in reducing children's anxiety during medical procedures. However, 7 of the 11 original studies included in this review were from the same research project, which may increase the risk of reporting bias. Also, more high-quality studies are needed in the future to verify its effectiveness for pain levels. IMPLICATIONS VRE can help children become familiar with the medical environment, overcome anxiety and fear, and learn about medical procedures in advance. This can enhance their cooperation during medical process, leading to a more positive medical experience.

Abstract
Background This study addresses the pervasive issue of heightened preoperative anxiety in healthcare, particularly among pediatric patients. Recognizing the various sources of anxiety, we explored both pharmacological and nonpharmacological interventions. Focusing on distraction techniques, including active and passive forms, our meta-analysis aimed to provide comprehensive insights into their impact on preoperative anxiety in pediatric patients. Methods Following the PRISMA and Cochrane guidelines, this meta-analysis and systematic review assessed the efficacy of pharmaceutical and distraction interventions in reducing pain and anxiety in pediatric surgery. This study was registered on PROSPERO (CRD42023449979). Results This meta-analysis, comprising 45 studies, investigated pharmaceutical interventions and distraction tactics in pediatric surgery. Risk of bias assessment revealed undisclosed risks in performance and detection bias. Distraction interventions significantly reduced preoperative anxiety compared to control groups, with notable heterogeneity. Comparison with Midazolam favored distraction techniques. Subgroup analysis highlighted varied efficacies among distraction methods, with a notable reduction in anxiety levels. Sensitivity analysis indicated stable results. However, publication bias was observed, suggesting a potential reporting bias. Conclusion Our study confirms distraction techniques as safe and effective for reducing pediatric preoperative anxiety, offering a valuable alternative to pharmacological interventions.

Preoperative Virtual Reality to Expose Patients With Breast Cancer to the Operating Room Environment: Feasibility and Pilot Case Series Study. JMIR Form Res 2024; 8:e46367. [PMID: 38231570 PMCID: PMC10831694 DOI: 10.2196/46367] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Revised: 11/16/2023] [Accepted: 12/04/2023] [Indexed: 01/18/2024] Open
Abstract
BACKGROUND Clinically elevated preoperative distress and anxiety are common among patients undergoing cancer surgery. Preoperative interventions have been developed to mitigate this distress and anxiety but are inconsistent in efficacy and feasibility for broad implementation. OBJECTIVE This preliminary pilot study aims to assess the feasibility and utility of a newly developed virtual reality (VR) intervention to expose patients awaiting breast cancer surgery to the operating room environment and a simulation of anesthetic induction. METHODS Patients undergoing breast cancer surgery (N=7) were assigned to the VR intervention or control (treatment as usual) group and completed self-report measures of distress and anxiety before surgery, on the day of surgery, and after surgery (5 and 30 d postoperatively). Those in the intervention group trialed the VR simulation 1 to 2 weeks preoperatively and provided qualitative and quantitative feedback. We assessed the feasibility of recruitment capability and study design and evaluated participants' impressions of the intervention using self-report rating scales and open-ended questions. We also descriptively examined distress and anxiety levels throughout the duration of the study. RESULTS Recruitment occurred between December 2021 and December 2022 and progressed slowly (rate: 1 participant/7 wk on average; some hesitancy because of stress and being overwhelmed). All participants who consented to participate completed the entire study. All participants were female and aged 56 (SD 10.56) years on average. In total, 57% (4/7) of the participants were assigned to the intervention group. On average, intervention participants spent 12 minutes engaged in the VR simulation. In general, the intervention was rated favorably (eg, clear information, enjoyable, and attractive presentation; mean% agreement 95.00-96.25, SD 4.79-10.00) and as helpful (mean% agreement 87.50, SD 25.00). Participants described the intervention as realistic (eg, "It was realistic to my past surgical experiences"), impacting their degree of preparedness and expectations for surgery (eg, "The sounds and sights and procedures give you a test run; they prepare you for the actual day"), and having a calming or relaxing effect (eg, "You feel more relaxed for the surgery"). CONCLUSIONS This preoperative VR intervention demonstrated preliminary feasibility among a sample of patients undergoing breast cancer surgery. Results and participant feedback will inform modifications to the VR intervention and the study design of a large-scale randomized controlled trial to examine the efficacy of this intervention.

[PMID: 37997773 PMCID: PMC10690102 DOI: 10.2196/52022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 10/07/2023] [Accepted: 10/09/2023] [Indexed: 11/25/2023] Open
Abstract
Background Virtual reality (VR) has shown promising levels of effectiveness in nursing education, pain management, and rehabilitation. However, meta-analyses have discussed the effects of VR usage in nursing unilaterally and inconsistently, and the evidence base is diffuse and varied. Objective We aimed to synthesize the combined evidence from meta-analyses that assessed the effects of nurses using VR technology on nursing education or patient health outcomes. Methods We conducted an umbrella review by searching for meta-analyses about VR intervention in clinical nursing practice on Web of Science, Embase, Cochrane, and PubMed, and in reference lists. Eligible studies were published in English between December 1, 2012, and September 20, 2023. Meta-analyses of ≤2 intervention studies and meta-analyses without 95% CI or heterogeneity data were excluded. Characteristic indicators, population information, VR intervention information, and 95% CIs were extracted. A descriptive analysis of research results was conducted to discern relationships between VR interventions and outcomes. I2 and P values were used to evaluate publication bias. AMSTAR (A Measurement Tool to Assess Systematic Reviews) 2 and the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) checklist were used to appraise literature quality. Results In total, 768 records were identified; 74 meta-analyses were included for review. The most reported VR study conditions were neuronursing (25/74, 34%), pediatric nursing (13/74, 18%), surgical and wound care (11/74, 15%), oncological nursing (11/74, 15%), and older adult nursing (10/74, 14%). Further, 30% (22/74) of meta-analyses reported publication bias, and 15% (11/74) and 8% (6/74) were rated as "high" based on AMSTAR 2 and the GRADE checklist, respectively. The main outcome indicators among all included meta-analyses were pain (37/214, 17.3%), anxiety (36/214, 16.8%), cognitive function (17/214, 7.9%), balance (16/214, 7.5%), depression (16/214, 7.5%), motor function (12/214, 5.6%), and participation in life (12/214, 5.6%). VR treatment for cognition, pain, anxiety, and depression was effective (all P values were <.05), while the utility of VR for improving motor function, balance, memory, and attention was controversial. Adverse effects included nausea, vomiting, and dizziness (incidence: range 4.76%-50%). The most common VR platforms were Pico VR glasses, head-mounted displays, the Nintendo Wii, and the Xbox Kinect. VR intervention duration ranged from 2 weeks to 12 months (typically ≥4 wk). VR session length and frequency ranged from 5 to 100 minutes and from 1 to 10 times per week, respectively. Conclusions VR in nursing has positive effects-relieving patients' pain, anxiety, and depression and improving cognitive function-despite the included studies' limited quality. However, applying VR in nursing to improve patients' motor function, balance, memory, and attention remains controversial. Nursing researchers need to further explore the effects and standard operation protocols of VR in clinical practice, and more high-quality research on VR in nursing is needed.

Using Immersive Virtual Reality Distraction to Reduce Fear and Anxiety before Surgery. Healthcare (Basel) 2023; 11:2697. [PMID: 37830734 PMCID: PMC10572694 DOI: 10.3390/healthcare11192697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 09/22/2023] [Accepted: 10/05/2023] [Indexed: 10/14/2023] Open
Abstract
Presurgical anxiety is very common and is often treated with sedatives. Minimizing or avoiding sedation reduces the risk of sedation-related adverse events. Reducing sedation can increase early cognitive recovery and reduce time to discharge after surgery. The current case study is the first to explore the use of interactive eye-tracked VR as a nonpharmacologic anxiolytic customized for physically immobilized presurgery patients. Method: A 44-year-old female patient presenting for gallbladder surgery participated. Using a within-subject repeated measures design (treatment order randomized), the participant received no VR during one portion of her preoperative wait and interactive eye-tracked virtual reality during an equivalent portion of time in the presurgery room. After each condition (no VR vs. VR), the participant provided subjective 0-10 ratings and state-trait short form Y anxiety measures of the amount of anxiety and fear she experienced during that condition. Results: As predicted, compared to treatment as usual (no VR), the patient reported having 67% lower presurgical anxiety during VR. She also experienced "strong fear" (8 out of 10) during no VR vs. "no fear" (0 out of 10) during VR. She reported a strong sense of presence during VR and zero nausea. She liked VR, she had fun during VR, and she recommended VR to future patients during pre-op. Interactive VR distraction with eye tracking was an effective nonpharmacologic technique for reducing anticipatory fear and anxiety prior to surgery. The results add to existing evidence that supports the use of VR in perioperative settings. VR technology has recently become affordable and more user friendly, increasing the potential for widespread dissemination into medical practice. Although case studies are scientifically inconclusive by nature, they help identify new directions for future larger, carefully controlled studies. VR sedation is a promising non-drug fear and anxiety management technique meriting further investigation.

Virtual reality psychological intervention helps reduce preoperative anxiety in patients undergoing carotid artery stenting: a single-blind randomized controlled trial. Front Psychol 2023; 14:1193608. [PMID: 37457093 PMCID: PMC10342209 DOI: 10.3389/fpsyg.2023.1193608] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Accepted: 06/14/2023] [Indexed: 07/18/2023] Open
Abstract
Objective This study aimed to explore the effectiveness and applicability of a psychological intervention using virtual reality (VR) to reduce preoperative anxiety in patients undergoing carotid artery stenting (CAS). Methods A total of 114 patients aged 18-86 years who were scheduled to undergo CAS were randomized to the VR and control groups. Patients in the VR group used a VR headset to view a 16-min psychological intervention video, while those in the control group used a tablet for viewing. The primary assessment instrument was the State Anxiety Inventory (S-AI), which was given 20 min before and after the intervention and 24 h after surgery. Secondary assessment tools were the Self-efficacy for Managing Chronic Disease (SEMCD-6) scale, which was completed before the intervention and 24 h after the operation, a smart bracelet to assess sleep quality, monitored in the evening before the operation, and the VR Suitability and Satisfaction Questionnaire, completed 24 h after the operation. Results The two groups were similar in terms of demographic information, preintervention STAI scores and preintervention SEMCD-6 scores (p > 0.05). S-AI scores were lower in both groups after the intervention and surgery, and the scores of the VR group were lower than those of the control group (p = 0.036, p = 0.014). SEMCD-6 scores post-surgery had improved in both groups, but the VR group had significantly higher scores than the control group (p = 0.005). Smart bracelet measurements showed no significant differences in postintervention sleep quality between the two groups (p = 0.540). For satisfaction, the VR group scored higher in all aspects except scheduling. A total of 47 (85.45%) patients reported having a comfortable experience, and only 5 (9.09%) experienced mild adverse effects. Conclusion The use of a virtual reality psychological intervention was beneficial to reduce the anxiety of patients before CAS and improved their self-efficacy. As virtual reality devices evolve and demonstrate better comfort and safety, more comprehensive and in-depth research of the use of VR to reduce patient anxiety should be performed in the future.Clinical trial registration:https://www.chictr.org.cn/showproj.aspx?proj=186412, identifier ChiCTR2200066219.
