How effective is virtual reality technology in palliative care? A systematic review and meta-analysis.

BACKGROUND: The efficacy of virtual reality for people living with a terminal illness is unclear. AIM: To determine the feasibility and effectiveness of virtual reality use within a palliative care setting. DESIGN: Systematic review and meta-analysis. PROSPERO (CRD42021240395). DATA SOURCES: Medline, Embase, AMED, PsycINFO, CINAHL, Cochrane Central Register of Controlled Trials and Web of Science were searched from inception to March 2021. Search terms included 'virtual reality' and 'palliative care'. Eligibility: (1) adult (>18 years old) with a terminal illness (2) at least one virtual reality session and (3) feasibility data and/or at least one patient outcome reported. The ROB-2 and ROBINS tools assessed risk of bias. The Grading of Recommendations, Assessment, Development and Evaluations (GRADE) tool assessed the quality of the evidence. Standardised mean differences (Hedges's g) were calculated from the pre- and post-data. A DerSimonian-Laird random effects model meta-analysis was conducted. RESULTS: Eight studies were included, of which five were in the meta-analysis. All studies had at least some concern for risk of bias. Virtual reality statistically significantly improved pain (p = 0.0363), tiredness (p = 0.0030), drowsiness (p = 0.0051), shortness of breath (p = 0.0284), depression (p = 0.0091) and psychological well-being (p = 0.0201). The quality of the evidence was graded as very low due to small sample sizes, non-randomisation methods and a lack of a comparator arm. CONCLUSIONS: Virtual reality in palliative care is feasible and acceptable. However, limited sample sizes and very low-quality studies mean that the efficacy of virtual reality needs further research.

Implementation, Adoption, and Perceptions of Telemental Health During the COVID-19 Pandemic: Systematic Review.

BACKGROUND: Early in 2020, mental health services had to rapidly shift from face-to-face models of care to delivering the majority of treatments remotely (by video or phone call or occasionally messaging) due to the COVID-19 pandemic. This resulted in several challenges for staff and patients, but also in benefits such as convenience or increased access for people with impaired mobility or in rural areas. There is a need to understand the extent and impacts of telemental health implementation, and barriers and facilitators to its effective and acceptable use. This is relevant both to future emergency adoption of telemental health and to debates on its future use in routine mental health care. OBJECTIVE: To investigate the adoption and impacts of telemental health approaches during the COVID-19 pandemic, and facilitators and barriers to optimal implementation. METHODS: Four databases (PubMed, PsycINFO, CINAHL, and Web of Science) were searched for primary research relating to remote working, mental health care, and the COVID-19 pandemic. Preprint servers were also searched. Results of studies were synthesized using framework synthesis. RESULTS: A total of 77 papers met our inclusion criteria. In most studies, the majority of contacts could be transferred to a remote form during the pandemic, and good acceptability to service users and clinicians tended to be reported, at least where the alternative to remote contacts was interrupting care. However, a range of impediments to dealing optimal care by this means were also identified. CONCLUSIONS: Implementation of telemental health allowed some continuing support to the majority of service users during the COVID-19 pandemic and has value in an emergency situation. However, not all service users can be reached by this means, and better evidence is now needed on long-term impacts on therapeutic relationships and quality of care, and on impacts on groups at risk of digital exclusion and how to mitigate these.
