Using virtual reality in palliative care: a systematic integrative review

A Systematic Review of Virtual Reality's Impact on Anxiety During Palliative Care

BACKGROUND

Virtual Reality (VR) is an emerging non-pharmacological treatment for anxiety in palliative care patients. Anxiety, a common symptom in this population, has a significant effect on living standards. The aim of this systematic review is to evaluate the effectiveness of VR interventions in reducing anxiety and improving quality of life in palliative care.

METHODS

The systematic review protocol was registered in PROSPERO (CRD42024517914). The comprehensive search was performed in nine databases, including PubMed, PsycINFO, and EMBASE, and included studies published up to 15 November 2024. RCTs, pilot studies, and feasibility trials involving adult palliative care patients in which VR interventions were used, were compared with standard care. Two reviewers independently extracted and assessed the quality of the data using the RoB 2 tool.

RESULTS

A total of 13 studies were considered eligible, with 333 participants aged 15 to 85 years old. In these experiments, anxiety decreased steadily, and in some cases mood and quality of life were improved significantly. The VR interventions ranged from guided nature walks to memory-training sessions. Sessions lasted between 5 and 30 min and ranged in duration from single sessions to daily use. Personalized and participatory VR-based content was particularly effective in alleviating anxiety. The heterogeneity of the study designs and VR protocols hampered meta-analysis, despite promising findings.

CONCLUSIONS

VR has considerable potential as an adjunctive anxiety therapy for palliative care. The personalization and immersion that VR provides are psychologically unique and have the potential to lower anxiety and improve well-being. But standardizing intervention protocols and more studies are required to define the best VR strategies and evaluate outcomes over the long term. The article highlights the promise of VR as part of palliative care as a viable bio-psycho-socio-spiritual approach.

The Tandem VR™ protocol: Synchronized nature-based and other outdoor experiences in virtual reality for hospice patients and their caregivers

Background

Nature-based and other outdoor virtual reality (VR) experiences in head-mounted displays (HMDs) offer powerful, non-pharmacological tools for hospice teams to help patients undergoing end-of-life (EOL) transitions. However, the psychological distress of the patient-caregiver dyad is interconnected and highlights the interdependence and responsiveness to distress as a unit. Hospice care services and healthcare need strategies to help patients and informal caregivers with EOL transitions.

Methods

Our study uses the synchronized Tandem VR TM approach where patient-caregiver dyads experience immersive nature-based and other outdoor VR content. This mixed methods study will recruit 20 patient-caregiver dyads (N = 40) enrolled in home hospice services nearing EOL. Dyads will experience a personalized nature-based and other outdoor VR experience lasting 5-15 min. Self-reported questionnaires and semi-structured interviews will be collected pre/post the VR intervention to identify the impacts of Tandem VR TM experiences on the QOL, pain, and fear of death in patient-caregiver dyads enrolled with hospice services. Additionally, this protocol will determine the acceptance of Tandem VR TM experiences by dyads as a non-pharmacological modality for addressing patient and caregiver needs. Acceptance will be quantified by the number of dyads accepting or declining the VR experience during recruitment.

Discussion

Using personalized, nature-based and other outdoor VR content, the patient-caregiver dyads can simultaneously engage in an immersive encounter may help alleviate symptoms associated with declining health and EOL phases for the patient and the often overburdened caregiver. This protocol focuses on meeting the need for person-centered, non-pharmacological interventions to reduce physical, psychological, and spiritual distress.

Experiences and perceptions of palliative care patients receiving virtual reality therapy: a meta-synthesis of qualitative studies

BACKGROUND

The combination of virtual reality (VR) and palliative care potentially represents a new opportunity for palliative care. Many previous studies have evaluated the application of VR therapy to patients with advanced disease receiving palliative care. However, patient-perspective reviews to comprehensively understand the actual experiences and feelings of patients and provide practical guidance for designing future studies are currently lacking. This review of qualitative evidence aimed to explore the experiences and perceptions of patients receiving VR therapy in palliative care.

METHODS

This study was conducted in accordance with the Enhancing Transparency in Reporting the Synthesis of Qualitative Research (ENTREQ) statement guidelines. Ten databases, namely, PubMed, Web of Science, EBSCO, OVID MEDLINE, Scopus, John Wiley, ProQuest, CNKI, WANFANG DATA, and SinoMed, were searched, and qualitative and mixed studies from the establishment of each database to June 30, 2023 were included. The Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research was used to assess the quality of the included studies. The data included in the literature were analyzed and integrated by "thematic synthesis" to formalize the identification and development of themes.

RESULTS

The nine selected studies altogether included 156 participants from seven hospice care facilities of different types and two oncology centers. Three key themes were identified: experiences of palliative care patients in VR therapy, the perceived value that palliative care patients gain in VR therapy, and perspectives of palliative care patients toward using VR therapy.

CONCLUSIONS

The patients' feedback covered discomfort caused by VR devices, good sense of experiences, and situations that affected the interactive experience. Some patients were unable to tolerate VR therapy or reported newer forms of discomfort. The findings indicated that VR therapy may be an effective approach to relieve patients' physical and psychological pain and help them gain self-awareness. Moreover, patients showed a preference for personalized VR therapy.

Research Trends and Highlights Toward Virtual Reality in Patients With Cancer: Bibliometric Analysis

This retrospective bibliometric analysis was conducted to explore research trends and identify studies in fields of nursing, virtual reality, and cancer. Data were obtained from the Web of Science database using an advanced search strategy. The study data were analyzed using the R Studio software and visualized using VOSviewer. A total of 594 studies were retrieved and analyzed from January 1995 to December 2021. It was determined that 59.4% of the studies were research articles and that these studies had been conducted by 2771 authors. The reviewed studies were produced by researchers from 25 countries and were published in 29 different journals. Of these, 169 were conducted by researchers in the United States. "Virtual reality" and "nursing" were found to be prominent topics. Studies on virtual reality in patients with cancer in the field of nursing have increased over the past 8 years. Researchers have actively conducted studies in this field. Prominent studies have covered various patients with cancer in all age groups and palliative care processes. It was seen that the majority of the studies were randomized controlled trials, reviews, and systematic reviews. In addition, studies have used virtual reality as a distraction method in the management of symptoms in patients with breast, lung, and pediatric cancers undergoing chemotherapy treatment. This study provides a detailed and up-to-date analysis of the findings obtained from the Web of Science database by emphasizing bibliometric models of virtual reality technologies in nursing patients with cancer. We believe that the current data on the use of virtual reality applications in patients with cancer will guide the clinical practice and scientific studies of healthcare professionals.

A Rapid Review of the Role of Virtual Reality in Care Delivery of Palliative Care and Hospice

Virtual reality (VR) is an emerging technology that can provide a nonpharmacological approach to symptom management for those with serious illnesses. The VR platform offers a unique perspective to connect patients with places and experiences they might otherwise miss. This rapid review aims to present the current literature on the uses and benefits of VR for palliative care and hospice patients. Through a systematic process, we identified 14 articles published between 2018 and 2023 that used VR as an interventional strategy for symptom management. The VR equipment includes a head-mounted display, such as the Oculus Go, and sometimes requires hand controllers or joysticks. Virtual reality software was contained exclusively in the head-mounted displays or required a laptop. Nature scenes, memorable locations, and the solar system are examples of options patients could select for the VR experience. Assessments of the intervention were measured before, during, after, and several hours afterward to evaluate benefits and potential adverse effects. Pain was the predominant symptom assessed in the studies. Overall, most of the studies focused on establishing the safety, efficacy, and feasibility of VR using a single-arm interventional method. Future research should implement randomized controlled trials, increase sample size, and expand to pediatric populations.

Integrating knowledge, skills, and attitudes: professional training required for virtual reality therapists in palliative care

Fully immersive virtual reality (VR) is an advanced technology increasingly studied and used in palliative care for symptom management. While the findings shed a positive light on its therapeutic potential, VR carries adverse effects, leading to ethical concerns. Based on the clinical experiences of a registered clinical psychologist who is also a certified thanatologist, we put forward a perspective on the importance of professional training for VR therapists in view of the possible risks posed by VR in palliative care. We propose professional trainings on knowledge, skills, and attitudes to ensure patients' safety while maximizing the therapeutic benefits of VR. Given the scarcity of reports on such an area, we hope this perspective article opens up discussions and contributes to current understanding and emerging future directions to ensure quality and ethical delivery of VR in palliative care.

Virtual reality use and patient outcomes in palliative care: A scoping review

Objective

Virtual reality is increasingly used in healthcare settings. Potentially, it's use in palliative carecould have a positive impact; however, there is limited evidence on the scope, purpose and patient outcomes relating to virtual reality use in this context. The objective of this scoping review is to chart the literature on virtual reality use in palliative care, identifying any evidence relating to biopsychosocial patient outcomes which could support its use in practice.

Methods

A scoping review of the literature, involving . a systematic search across 10 electronic bibliographic databases in December 2021, . Eligibility criteria were primary research studies, of any research designwithin a 10-year timeframe, which reported on virtual reality use and patient outcomes in palliative care. A total of 993 papers were identified, andcomprehensive screening resulted in 10 papers for inclusion.

Results

This scoping review identified 10 papers addressing virtual reality in palliative care, published within a three-year timeframe 2019-2021. Research methodologies included mixed methods, quantitative and qualitative. The evidence highlightsvirtual reality use with patients receiving palliative care in a variety of settings, and data around useability, feasibility and acceptability is positive. However, the evidence regarding biopsychosocial patient outcomes linked to virtual reality use is limited.

Conclusion

Virtual reality is gathering momentum in palliative care and is potentially a helpful intervention; however more research is needed to underpin the evidence base supporting its application, particularly in understanding the impact on biopsychosocial patient outcomes and ascertaining the best approach for measuring intervention effectiveness.
