The Impact of Virtual Reality on Anxiety and Pain During US-Guided Breast Biopsies: A Randomized Controlled Clinical Trial.

OBJECTIVE: To investigate the efficacy of immersive virtual reality (VR) in combination with standard local anesthetic for mitigating anxiety and pain during US-guided breast biopsies compared to local anesthetic alone. METHODS: Patients scheduled for US-guided biopsy were invited to participate. Eligible patients were females 18 years of age or older. Patients were randomized to VR or control group at a 1:1 ratio. Patients in the VR group underwent biopsy with the addition of a VR experience and patients in the control group underwent usual biopsy. Patient-perceived levels of anxiety and pain were collected before and after biopsy via the State-Trait Anxiety Inventory (STAI) and Visual Analog Scale (VAS). Physiological data were captured during biopsy using a clinically validated wristband. Differences in anxiety, pain, and physiologic data were compared between the VR and control group. RESULTS: Sixty patients were enrolled. After excluding 2 patients with VR device malfunction, there were 29 patients in the VR and 29 patients in the control group for analysis. The VR group had reduced anxiety compared to the control group based on postintervention STAI (P <.001) and VAS (P = .036). The VR group did not have lower pain based on postintervention VAS (P = .555). Physiological measures showed higher RR intervals and decreased skin conductance levels, which are associated with lower anxiety levels in the VR group. CONCLUSION: Use of VR in addition to standard local anesthetic for US-guided breast biopsies was associated with reduced patient anxiety. Virtual reality may be a useful tool to improve the patient biopsy experience.

Designing and developing a nature-based virtual reality with heart rate variability biofeedback for surgical anxiety and pain management: evidence from total knee arthroplasty patients.

OBJECTIVES: Total knee arthroplasty (TKA) is one of the most common joint surgeries, with over a million procedures performed annually in the US. Over 70% of patients report moderate to high pain and anxiety surrounding TKA surgery, and 96% are discharged with an opioid prescription. This population requires special attention as approximately 90% of TKA patients are older adults and one of the riskiest groups prone to misusing opioids. This study aimed to develop and compare the efficacy of nature-based virtual reality (VR) with heart rate variability biofeedback (HRVBF) to mitigate surgical pain and anxiety. METHODS: This randomized control trial recruited 30 patients (mean age = 66.3 ± 8.2 years, 23 F, 7 M) undergoing TKA surgery and randomly assigned to a control, 2D video with HRVBF, or VR with HRVBF group. A visual analog scale (VAS) was used to measure pain levels before and after the intervention. In addition, a second VAS and the State-Trait Anxiety Inventory (STAI) were used to measure anxiety before and after the intervention. Electrocardiogram (ECG) was used to continuously measure HRV and respiration rate in preoperative and postoperative settings. RESULTS: VR and 2D-video with HRVBF decreased pain and anxiety post-intervention compared with the control group, p's <.01. On analyzing physiological signals, both treatment groups showed greater parasympathetic activity levels, and VR with HRVBF reduced pain more than the 2D video, p < .01. CONCLUSIONS: Nature-based VR and 2D video with HRVBF can mitigate surgical pain and anxiety. However, VR may be more efficacious than 2D video in reducing pain.

Risk-adjusted policies to minimise perioperative staffing shortages during a pandemic: An agent-based simulation study.

Healthcare workers' (HCWs) safety and availability to care for patients are critical during a pandemic such as the one caused by severe acute respiratory syndrome coronavirus 2. Among providers of different specialities, it is critical to protect those working in hospital settings with a high risk of infection. Using an agent-based simulation model, various staffing policies were developed and simulated for 90 days using data from the largest health systems in South Carolina. The model considers staffing policies that include geographic segregation, interpersonal contact limits, and a combination of factors, including the patient census, transmission rates, vaccination status of providers, hospital capacity, incubation time, quarantine period, and interactions between patients and providers. Comparing the existing practices to various risk-adjusted staffing policies, model predictions show that restricted teaming and rotating schedules significantly (p-value <0.01) reduced weekly HCW unavailability and the number of infected HCWs by 22% and 38%, respectively, when the vaccination rates among HCWs were lower (<75%). However, as the vaccination rate increases, the benefits of risk-adjusted policies diminish; and when 90% of HCWs were vaccinated, there were no significant (p-value = 0.09) benefits. Although these simulated outcomes are specific to one health system, our findings can be generalised to other health systems with multiple locations.

Digital Practices by Citizens During the COVID-19 Pandemic: Findings From an International Multisite Study.

BACKGROUND: The COVID-19 pandemic brought digital practices and engagement to the forefront of society, which were based on behavioral changes associated with adhering to different government mandates. Further behavioral changes included transitioning from working in the office to working from home, with the use of various social media and communication platforms to maintain a level of social connectedness, especially given that many people who were living in different types of communities, such as rural, urban, and city spaces, were socially isolated from friends, family members, and community groups. Although there is a growing body of research exploring how technology is being used by people, there is limited information and insight about the digital practices employed across different age cohorts living in different physical spaces and residing in different countries. OBJECTIVE: This paper presents the findings from an international multisite study exploring the impact of social media and the internet on the health and well-being of individuals in different countries during the COVID-19 pandemic. METHODS: Data were collected via a series of online surveys deployed between April 4, 2020, and September 30, 2021. The age of respondents varied from 18 years to over 60 years across the 3 regions of Europe, Asia, and North America. On exploring the associations of technology use, social connectedness, and sociodemographic factors with loneliness and well-being through bivariate and multivariate analyses, significant differences were observed. RESULTS: The levels of loneliness were higher among respondents who used social media messengers or many social media apps than among those who did not use social media messengers or used ≤1 social media app. Additionally, the levels of loneliness were higher among respondents who were not members of an online community support group than among those who were members of an online community support group. Psychological well-being was significantly lower and loneliness was significantly higher among people living in small towns and rural areas than among those living in suburban and urban communities. Younger respondents (18-29 years old), single adults, unemployed individuals, and those with lower levels of education were more likely to experience loneliness. CONCLUSIONS: From an international and interdisciplinary perspective, policymakers and stakeholders should extend and explore interventions targeting loneliness experienced by single young adults and further examine how this may vary across geographies. The study findings have implications across the fields of gerontechnology, health sciences, social sciences, media communication, computers, and information technology.

Daily exposure to virtual nature reduces symptoms of anxiety in college students.

Exposure to natural environments offers an array of mental health benefits. Virtual reality provides simulated experiences of being in nature when outdoor access is limited. Previous studies on virtual nature have focused mainly on single "doses" of virtual nature. The effects of repeated exposure remain poorly understood. Motivated by this gap, we studied the influence of a daily virtual nature intervention on symptoms of anxiety, depression, and an underlying cause of poor mental health: rumination. Forty college students (58% non-Hispanic White, median age = 19) were recruited from two U.S. universities and randomly assigned to the intervention or control group. Over several weeks, anxious arousal (panic) and anxious apprehension (worry) decreased with virtual nature exposure. Participants identifying as women, past VR users, experienced with the outdoors, and engaged with the beauty in nature benefited particularly strongly from virtual nature. Virtual nature did not help symptoms of anhedonic depression or rumination. Further research is necessary to distinguish when and for whom virtual nature interventions impact mental health outcomes.

A data driven policy to minimise the tuberculosis testing cost among healthcare workers.

INTRODUCTION: The Centres for Disease Control and Prevention (CDC) mandates that healthcare employees at high-risk exposure to Tuberculosis (TB) undergo annual testing. Currently, two methods of TB testing are used: a two-step skin test (TST) or a whole-blood test (IGRA). Healthcare leadership's test selection must account for not only direct costs such as procedure and resources but also indirect costs, including employee workplace absence. METHODS: A mathematical model based on Upstate South Carolina's largest health system affecting over 18,000 employees on six campuses was developed to investigate the value loss perspective of these testing methods and assist in decision-making. A process flow map identified the varied direct and indirect costs for each test for four employee types, and 6 travel-to-testing-site times were calculated. RESULTS: The switching point between testing procedures that minimised total system costs was most influenced by employee salary compared to travel distance. Switching from the current hospital policy to an integrated TST/IGRA testing could reduce TB compliance costs by 28%. CONCLUSIONS: This study recommends an integrated approach as cost-effective for large health systems with multiple campuses while considering the direct and indirect costs. When accounting for 'inconvenience costs' (stress, etc.) associated with visits, IGRAs are recommended irrespective of employee salary.

Impact of Surgical Table Orientation on Flow Disruptions and Movement Patterns during Pediatric Outpatient Surgeries.

(1) Background: The surgical table within a typical ambulatory surgery operating room is frequently rotated and placed in different orientations to facilitate surgery or in response to surgeon preferences. However, different surgical table orientations can impact access to different work zones, areas and equipment in the OR, potentially impacting workflow of surgical team members and creating patient safety risks; (2) Methods: This quantitative observational study used a convenience sample of 38 video recordings of the intraoperative phase of pediatric outpatient surgeries to study the impacts of surgical table orientation on flow disruptions (FDs), number of contacts between team members and distance traveled; (3) Results: This study found that the orientation of the surgical table significantly influenced staff workflow and movement in the OR with an angled surgical table orientation being least disruptive to surgical work. The anesthesia provider, scrub nurse and circulating nurse experienced more FDs compared to the surgeon; (4) Conclusions: The orientation of the surgical table matters, and clinicians and architects must consider different design and operational strategies to support optimal table orientation in the OR.
