Evaluating the Impact of VR-therapy on BPSD and QoL of Individuals With Dementia Admitted to Hospital

Behavioural and Psychological Symptoms of Dementia (BPSD) (including hallucinations, delusions, aggression, restlessness, agitation, wandering, anxiety, depression, elation, euphoria, disinhibition, motor disturbances, nighttime behaviours, and appetite disturbances) represent an aspect of dementia particularly difficult to manage for which new treatments are urgently needed. Current means to manage BPSD typically involve medications (e.g. anti-psychotics, anti-depressants, sedatives) associated with negative side effects such as lethargy, loss-of-self, cognitive decline, and increased risk of falls, and/or applying physical barriers and restraints (alarms, locks, Buxton chairs, tethers) that can cause pressure sores, injury, infection, as well as negative psychological effects such as anxiety, distress, and aggression. Although options for non-pharmacological management of BPSD in acute care exist (e.g. reminiscence therapy, therapeutic touch, music therapy), they are seldom implemented in practice due to lack of time, resources, and/or training. Exposure to natural environments (seeing greenery, hearing outside natural sounds) has been shown to enhance wellbeing, reduce depression, anxiety, and stress levels, and decrease hospital length-of-stay for inpatients. Through VR technology, one's surroundings can be seamlessly replaced by a virtual world of their choosing. Based on previous studies and expert consultation, we created a library of VR experiences depicting calming nature scenes (peaceful lake, refreshing forest, cheerful playground) designed specifically for people with dementia, as a prototype for introducing immersive VR-therapy to hospitals, long term care facilities and private homes. The goal of VR-therapy is to help manage BPSD and stimulate psychological/cognitive health and daytime engagement for people with dementia. The RCT will be informed by our prior pilot study conducted in the hospitalist medicine department of Michael Garron Hospital with inpatients with dementia to validate the proposed RCT study protocol (processes, methods, recruitment strategy, resource requirements, timelines) as well as by previous feasibility studies in outpatients that showed it is safe and feasible to use VR/HMDs for people with dementia.
