Filter by:This research is being done to find out if patients and caregivers who use the iPREPARED mobile health technology experience less delirium, a type of acute confusion, and if they do experience delirium, the delirium will be less severe and distressful. iPREPARED prepares patients and caregivers on what to expect during their hospital stay and provides instructions and resources on how to use non-pharmacologic strategies like re-orientation, distraction techniques, and other activities to maintain their brain health during their hospital stay.
Delirium has been long considered as a major contributor to cognitive impairments following a critical illness. Currently, both pharmacologic and non-pharmacologic prevention and treatment strategies are used in the intensive care unit, despite these strategies remaining controversial. However, with previous studies showing the feasibility of using virtual reality (VR) within the critical care setting, the investigators propose to use this technology to investigate the effect of 360-degree immersive virtual reality stimulation on the incidence of delirium in the ICU. Stimulation will be provided for 30 minutes, three times a day, evenly spaced between 7:00 AM and 7:00 PM, using a commercially available head-mounted display. The investigators hypothesize that by providing relaxing virtual environments to patients through a head-mounted display and headphones, the incidence of delirium will be lower compared to the control group receiving no VR stimulation. Secondary outcomes will include evaluating the movement patterns and intensity between the intervention and control group, and between patients with and without delirium, using inertial measurement units and an under mattress bed sensor. It is hypothesized that it will be possible to detect difference in movement patterns between groups and identify patterns indicating the presence or absence of delirium. Secondary objective also include the evaluation of the effect of VR on duration of delirium. Here it is hypothesized that the duration of delirium will be shorter in participants receiving the VR stimulation compared to those in the control group. Physiological parameters (e.g. heart rate, respiration rate, oxygen saturation, etc.) will also be recorded during the stimulation to further understand what, if any, effect VR has.
By the year 2038, over a million Canadians are expected to have Alzheimer's disease, a type of dementia. Dementia increases the risk of nursing home placement among the elderly more than fivefold. Given the exceptionally vulnerable nature of this patient population, there is a pressing need to ensure that the clinical care they receive is evidence-based, tailored specifically for them, and meeting the high standards of quality that would be expected in any other health-care setting. Delirium is a sudden and severe change in brain function that can cause a person to appear confused or disoriented, have memory loss, and have difficulties maintaining focus. It is an urgent care issue facing elderly patients residing in nursing homes, or long-term care (LTC) facilities. Delirium is a significant cause of illness and mortality, affecting between 10%-89% of LTC patients, but little research has focused on delirium prevention in the LTC setting. This study will assess the effectiveness of a LTC multicomponent delirium prevention program (PREPARED Trial intervention). The PREPARED Trial intervention is an intervention provided to nursing staff working in LTC facilities that consists of four components: a decision tree, an instruction manual, a training package, and a toolkit. The feasibility and acceptability of the PREPARED Trial intervention has already been successfully demonstrated; however, a thorough and well-designed large scale study is needed in order to confirm its ability to reduce delirium among LTC residents. In this study, approximately 40-50 LTC facilities will be randomized to either receive the PREPARED Trial intervention or to receive usual care. At the end of the 4-year study period, the investigators will be able to demonstrate the degree to which the PREPARED Trial intervention reduces: 1) the number of new cases of delirium; 2) delirium severity; and 3) the duration of delirium episodes. This study will provide the blueprint of a program that can be transferable to LTC facilities across Canada.
Delirium is common in the elderly after orthopedic surgery and is associated with worse outcomes. Continuous femoral nerve block is frequently used for postoperative analgesia after total knee arthoplasty. The investigators hypothesize that dexmedetomidine, when combined with ropivacaine for continuous femoral nerve block, can reduce the incidence of delirium and improve the long-term outcome in elderly patients after total knee arthroplasty.
The research program explores how delirium influenced brain function in patients surviving delirium and septic encephalopathy from a non neurological specialized ICU cohort from 2013 to 2015 in Rigshospitalet (Glostrup).
For patients undergoing mechanical ventilation, light sedation is better than deep sedation for the outcomes, which is manifested as shortened length of ICU stay, shortened duration of mechanical ventilation, and decreased mortality. In a recent study of the investigators, low-dose dexmedetomidine without sedative effects (0.1 ug/kg/h) improved sleep quality and reduced the incidence of delirium in elderly patients admitted to the ICU after surgery. The investigators hypothesize that, for ICU patients with prolonged mechanical ventilation, low-dose dexmedetomidine infusion (0.1 ug/kg/h) may also be effective in decreasing delirium. The purpose of this study is to investigate whether low-dose dexmedetomidine infusion can reduce the incidence of delirium in ICU patients with prolonged duration of mechanical ventilation (>= 24 hours).
