Numerous studies have shown that delirium is not very well recognized in Emergency Departments. This may be attributed to the fluctuating nature of this condition. Patients may seem normal upon clinical assessment, and then quickly become confused. The main purpose of the PREDDICT-PREV study is to look at whether a video game can help ED staff to identify persons 65 years and older who are at high risk of delirium. Delirium is a state of confusion or disorientation that can develop rapidly as a complication of medical care. The results of the current study will tell us whether the PrEDDICT-PREV App can help ED staff recognize patients at high risk of delirium. Approximately 1375 patients will participate in this study in five hospitals across Canada, of which 275 will be included at the CHU de Québec – Université Laval.
