Brief summary
The goal of this substudy (main study NCT04498585) is to determine the feasibility of applying virtual reality stimulation to patients in the intermediate care unit. Patients on this ward are generally more awake and alert than patients in the intensive care unit, thereby they are able to provide feedback about their experience. As the intermediate care unit is not without stress, examining the physiological parameters (e.g., heart rate, respiration rate, blood pressure, etc.) could also provide telling information as to the calming effect of virtual reality. The movements of these patients are also recorded using accelerometers which will provide valuable information about the characteristics of the movements that patients make while confined to their beds. These movements can act as a reference for further investigation into movements related to delirium which is a secondary outcome measure of the main study.
Interventions
Participants in the intervention group will be provided with up to 30 minutes of relaxing, 360-degree virtual reality (VR) stimulation and corresponding sounds, twice in 24 hours during their stay on the intermediate care unit.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Acceptability of providing virtual reality stimulation | Recorded immediately after every VR stimulation | To determine the acceptability of providing VR stimulation to patients in the intermediate care (IMC) unit based on 1) the subjective perception of the feedback, and 2) the ability of the stimulation to be maintained for minimum 20 minutes. |
| Safety of providing virtual reality stimulation | Safety will be determined based on the reporting of adverse or serious adverse events in the 1-hour following the completion of the VR stimulation. | To determine the safety based on the adverse or serious adverse events reported by the medical staff, or the subjective reporting of the participant who received the VR stimulation. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Blood Pressure | Recorded during entire stay in the IMC (up to 24 hours) | Changes in blood pressure (mmHg) recorded from the patient will be compared from the start of the stimulation to the end of the stimulation period. |
| Heart Rate | Recorded during entire stay in the IMC (up to 24 hours) | Changes in heart rate (beats per minute) recorded from the patient will be compared from the start of the stimulation to the end of the stimulation period. |
| Respiration Rate | Recorded during entire stay in the IMC (up to 24 hours) | Changes in respiration rate (breaths per minute) recorded from the patient will be compared from the start of the stimulation to the end of the stimulation period. |
| Oxygen Saturation | Recorded during entire stay in the IMC (up to 24 hours) | Changes in oxygen saturation (%) recorded from the patient will be compared from the start of the stimulation to the end of the stimulation period. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Movement Intensity before and after VR stimulation | Recorded during entire stay in the IMC (up to 24 hours) | Movement intensity, measured as acceleration and rotation, will be measured using inertial measurement units. The data will be used to determine if there is a change in intensity between periods before, during, or after stimulation. |
| Movement Patterns before and after VR stimulation | Recorded during entire stay in the IMC (up to 24 hours) | Movement patterns, measured as acceleration and rotation, will be measured using inertial measurement units. The data will be used to determine if there is a change in pattern between periods before, during, or after stimulation. |
| Cognitive Functioning | Recorded during entire stay in the IMC (up to 24 hours) | Cognitive abilities will be measured using the Montreal Cognitive Assessment (MoCA). |
