      PS01.01 - Smart Home Technology Detecting Nighttime Wandering in Persons with Dementia (ID 476)

      Steve Burton, /

      • Abstract

      Purpose/Objectives:
      The Wander Detection and Diversion (WDD) system is designed to assist caregivers and persons with dementia (PWD) that are at risk of wandering at night. Using smart home technologies such as sensors, smart bulbs, pressure mats and speakers, the system detects when the PWD gets out of bed and automatically provides cue lighting to guide them safely to the washroom and back. It will also guide them back to bed through audio prompts if they near an exit – all without disturbing the caregiver in any way. The caregiver is only woken if the PWD opens an exit door. The system has a flexible design allowing it to be adapted to meet the needs of diverse residences and users such as protection for multiple exit doors or coverage for higher risk areas of the residence such as a kitchen or stairs. The message to the PWD is also customized both in the content and the voice. The goal of the system is to improve the caregiver’s sleep and reduce their stress while supporting the safety of the PWD.


      Methodology/Approach:
      Our team of researchers installs the smart technology devices into participants houses for a 12 week trial period. Before the installation the caregiver is asked a series of questions regarding their stress, depression and anxiety levels, as well as questions regarding how many hours of sleep in a night they are getting and how often their PWD exits the bed during the night. During the 12 weeks the participants are contacted every 2 weeks to ensure satisfaction with the technology. At the end of the 12 weeks the caregiver is asked the same questions as the date of the install, comparing their stress, depression and anxiety levels after having the system in their home for 12 weeks.


      Finding/Results:
      3 male and 1 female participant, age range from 59 years old to 98 years old, had this system installed in their houses for a 12 week trial period. There was an average depression rate of 6.5 and an average anxiety rate of 8 at the beginning of the trial, at the end of the trial the average depression decreased to 4.5 and the average anxiety rate decreased to 6.7. The only issues caregivers have had thus far in the research is that there were a few technical issues and that at the end of the 12 weeks the system had to be uninstalled.


      Conclusion/Implications/Recommendations:
      The study is not completed, however thus far, all participants have been satisfied and said that they felt less stressed, depressed and anxious. All participants were able to get more hours of sleep in a given night, and those who did not had reasons unrelated to the system and their PWD. Next steps include testing other types of sensors and looking for a private sector partner.


      140 Character Summary:
      An off-the-shelf smart home technology solution is installed in participants’ homes for a 12 week trial to detect and redirect nighttime wandering in PWD.
