The Efficacy of Virtual Reality for Persistent Cancer Pain: A Call for Research

Virtual reality in specialist palliative care: a feasibility study to enable clinical practice adoption

BACKGROUND

The use of virtual reality (VR) is increasing in palliative care. However, despite increasing interest in VR, there is little evidence of how this technology can be implemented into practice.

AIMS

This paper aims to: (1) explore the feasibility of implementing VR therapy, for patients and caregivers, in a hospital specialist inpatient palliative care unit and a hospice, and (2) to identify questions for organisations, to support VR adoption in palliative care.

METHODS

The Samsung Gear VR system was used in a hospital specialist palliative inpatient unit and a hospice. Patients and caregivers received VR distraction therapy and provided feedback of their experience. Staff completed a feedback questionnaire to explore their opinion of the usefulness of VR in palliative care. A public engagement event was conducted, to identify questions to support implementation of VR in palliative care settings.

RESULTS

Fifteen individuals (12 (80%) patients and 3 (20%) caregivers) participated. All had a positive experience. No adverse effects were reported. Ten items were identified for organisations to consider ahead of adoption of VR in palliative care. These were questions about: the purpose of VR; intended population; supporting evidence; session duration; equipment choice; infection control issues; content choice; setting of VR; person(s) responsible for delivery and the maintenance plan.

CONCLUSIONS

It is feasible to use VR therapy in palliative care; however, further evidence about its efficacy and effectiveness is needed. Palliative care practitioners considering VR use should carefully consider several factors, to ensure that this technology can be used safely and effectively in clinical practice.

Identification of Digital Health Priorities for Palliative Care Research: Modified Delphi Study

BACKGROUND

Developments in digital health have the potential to transform the delivery of health and social care to help citizens manage their health. Currently, there is a lack of consensus about digital health research priorities in palliative care and a lack of theories about how these technologies might improve care outcomes. Therefore, it is important for health care leaders to identify innovations to ensure that an increasingly frail population has appropriate access to palliative care services. Consequently, it is important to articulate research priorities as the first step in determining how finite resources should be allocated to a field saturated with rapidly developing innovation.

OBJECTIVE

The aim of this study is to identify research priority areas for digital health in palliative care.

METHODS

We selected digital health trends, most relevant to palliative care, from a list of emerging trends reported by a leading institute of quantitative futurists. We conducted 2 rounds of the Delphi questionnaire, followed by a consensus meeting and public engagement workshop to establish a final consensus on research priorities for digital technology in palliative care. We used the views of public representatives to gain their perspectives on the agreed priorities.

RESULTS

A total of 103 experts (representing 11 countries) participated in the first Delphi round. Of the 103 experts, 55 (53.3%) participated in the second round. The final consensus meetings were attended by 10.7% (11/103) of the experts. We identified 16 priority areas, which involved many applications of technologies, including care for patients and caregivers, self-management and reporting of diseases, education and training, communication, care coordination, and research methodology. We summarized the priority areas into eight topics: big data, mobile devices, telehealth and telemedicine, virtual reality, artificial intelligence, smart home, biotechnology, and digital legacy.

CONCLUSIONS

The priorities identified in this study represent a wide range of important emerging areas in the fields of digital health, personalized medicine, and data science. Human-centered design and robust governance systems should be considered in future research. It is important that the risks of using these technologies in palliative care are properly addressed to ensure that these tools are used meaningfully, wisely, and safely and do not cause unintentional harm.

Feasibility and acceptability of virtual reality for cancer pain in people receiving palliative care: a randomised cross-over study

CONTEXT

Pain management in palliative care remains inadequate; the development of innovative therapeutic options is needed.

OBJECTIVES

To determine the feasibility and preliminary effectiveness for larger randomised controlled trials of 3D head-mounted (HMD) virtual reality (VR) for managing cancer pain (CP) in adults.

METHODS

Thirteen people receiving palliative care participated in a single-session randomised cross-over trial, after which they completed a qualitative semi-structured interview. We also compared the effects of 3D HMD VR and 2D screen applications on CP intensity and levels of perceived presence. Feasibility was assessed with recruitment, completion rates and time required to recruit target sample.

RESULTS

Although recruitment was slow, completion rate was high (93%). Participants reported that the intervention was acceptable and caused few side effects. Although participants reported significantly reduced CP intensity after 3D HMD VR (1.9 ± 1.8, P = .003) and 2D screen applications (1.5 ± 1.6, P = .007), no significant differences were found between interventions (-.38 ± 1.2, 95% CI: -1.1-.29, P = .23). Participants reported significantly higher levels of presence with the 3D HMD VR compared to 2D screen (60.7 ± SD 12.4 versus 34.3 ± SD 17.1, mean 95% CI: 16.4-40.7, P = .001). Increased presence was associated with significantly lower pain intensity (mean 95% CI: -.04--0.01, P = 0.02).

CONCLUSIONS

Our preliminary findings support growing evidence that both 3D and 2D virtual applications provide pain relief for people receiving palliative care. Given the relative lack of cybersickness and increasing access to portable VR, we suggest that larger clinical studies are warranted.
