Brief Summary

Behavioural and Psychological Symptoms of Dementia (BPSD) (such as aggression, restlessness, agitation, wandering, anxiety, depression) are common to most people with dementia at some point during their illness and represent an aspect of dementia particularly difficult to manage. There is growing attention to the therapeutic effects of natural environments on people's health. 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. Virtual Reality (VR) is a novel technology that uses a Head Mounted Display (HMD) to generate simulated immersive experiences that elicit perceptions and behaviors similar to those in real life and can make one feel as though they are truly present in another place. Based on scientific research, previous studies, and expert consultation, we created a library of VR experiences depicting calming nature scenes designed specifically for people with dementia.

The objectives of this RCT are 1) to evaluate the effects of VR-therapy on BPSD and the hospital care experience of in-patients with dementia and/or delirium admitted to an acute care hospital, 2) to determine the usability, tolerability, and safety of VR-therapy for patients with dementia and/or delirium admitted to acute care, 3) determine the effect of VR-therapy on quality of life for patients with dementia and/or delirium admitted to acute care and 4) to explore a framework for introducing non-pharmacological therapies in acute care hospitals.

Our hypotheses are 1) VR-therapy helps manage BPSD (e.g. decrease anxiety, aggression, depression, violent behaviors, incidents of wandering), and may decrease the amount and/or frequency of sedatives and anti-depressant medication administered and/or the number of incidents that require restraints, and the number of falls, in people with dementia and/or delirium admitted to an acute care hospital. 2) VR-therapy will improve the quality of life for individuals with dementia and/or delirium admitted to an acute care hospital (operationalized through conducting a validated instrument to measure quality of life for people with dementia). 3) VR-therapy is safe and feasible to administer to individuals with dementia and/or delirium admitted to an acute care hospital (with assistance from their circle of care members and/or caregivers).

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
Intervention	VR-therapy	The intervention arm will receive a VR-therapy session every 24-72 hours of their stay in the hospital. Participants will view specially designed 360-degree VR films using a Virtual Reality head mounted display for a maximum of 20 minutes per session.

Primary Outcome Measures

Name	Time	Method
Number of pressure ulcers during the hospital stay	Throughout the acute hospitalization, an average of 10.6 days	All pressure ulcers that developed during the acute hospitalization that were recorded in the electronic medical record will be assessed for all participants
Changes in Behavioural and Psychological Symptoms of Dementia (BPSD) during the hospital stay	Throughout the acute hospitalization, an average of 10.6 days	BPSD recorded in the electronic medical record during the acute hospitalization, averaging 10.6 days, will be assessed for all participants. The E-BEHAVE-AD will be administered to all participants on days 1 and 4-7 of hospitalization
Number of falls without injury during the hospital stay	Throughout the acute hospitalization, an average of 10.6 days	All falls without injury that occurred during the current acute hospitalization that were recorded in the electronic medical record will be assessed for all participants
Discharge disposition	At the end of the acute hospitalization, an average of 10.6 days	Discharge disposition - The disposition (also called Status) of the patient at time of hospital discharge (i.e., discharged to home, expired, etc.). For each participant, the discharge disposition, will be collected from the electronic medical record on the last day of acute hospitalization
30-day readmission rate	Within 30 days following the last day of acute hospitalization which is an average of 10.6 days	The number of re-admissions to acute care at this hospital site in the 30 days following discharge will be collected for all participants.

Number of falls with injury during the hospital stay	Throughout the acute hospitalization, an average of 10.6 days	All falls with injury that occurred during the acute hospitalization that were recorded in the electronic medical record will be assessed for all participants
Length of acute hospital stay	At the end of the acute hospitalization, an average of 10.6 days	Number of days of acute hospitalization as recorded by the site staff, will be collected from the electronic medical record after patient's discharge from acute care for all study participants

Secondary Outcome Measures

Name	Time	Method
Usability of VR-therapy	Throughout the acute hospitalization, an average of 10.6 days	Usability of VR-therapy will be assessed at each study session (every 24-72 hours of the hospital stay) through a semi-structured interview conducted immediately after VR-therapy. Usability of VR-therapy will only be assessed in the intervention arm.
Number of participants with VR-therapy related adverse events as assessed by the post-intervention semi-structured interview and research coordinator observations	Throughout the acute hospitalization, an average of 10.6 days	Participants in the intervention arm will be asked if the VR head mounted display was painful, too heavy, or otherwise uncomfortable. Participants with hearing aids will be asked if they heard buzzing noises during VR-therapy. Participants will be asked if VR-therapy made them feel nervous/anxious, confused/disoriented, nauseous, or any other negative side effect. The research coordinator will observe participant reactions during VR-therapy and record behavior suggesting an unpleasant experience. Participant reactions during VR-therapy will be monitored and the semi-structured interview will be administered immediately after VR-therapy at each session (every 24-72 hours of the hospital stay) for participants in the intervention arm.
Participant Experience and Satisfaction of VR-therapy	Throughout the acute hospitalization, an average of 10.6 days	Participants in the intervention arm will be asked if they had fun and felt relaxed during VR-therapy. They will be asked open-ended questions about what content they enjoyed most and would like to see in the future. They will be asked if they would like to own VR, recommend VR to a friend, and would like to try VR again. Participant reactions during VR-therapy will be monitored by the research coordinator. Perceived participant enjoyment, relaxation, and engagement will be recorded. Instances of participant vocalizations and reminiscence will be recorded. Participant experience and satisfaction will be assessed at each study session (every 24-72 hours of the hospital stay) for participants in the intervention arm.
In-Hospital Quality of Life Observational Scale	Throughout the acute hospitalization, an average of 10.6 days	The scale contains 11 items. Total scores range from -22 to 22. Higher scores indicate a higher in-hospital quality of life. This scale is adapted from the Quality of Life in Late-Stage Dementia (QUALID) Scale. Scale will be administered at the beginning of each study session (every 24-72 hours of the hospital stay) for all participants.
