Often times, elderly patients suffer from dementia resulting in memory loss and decreased judgment over time.
This leads to problems when patients wander about. Since numerous incidents have been reported involving
confused wandering patients that have led to serious accidents, a function that monitors patient locations in order to
prevent incidents is urgently needed. The prevalence of patients with dementia is particularly high in nursing homes,
and almost all such facilities have problem with wandering patients. In many large nursing homes, the problem is
exacerbated by the range over which a patient can wander, which makes it very hard for care workers to maintain
visual contact with all patients. Thus, there is a strong demand for a technology capable of monitoring patient
locations within nursing homes.
