The DIPH.DEM study

DIPH.DEM investigates the activities and symptoms of people with dementia living in nursing homes. We want to evaluate participants’ physical, mental and social activities, because many residents experience restlessness, pain and poor sleep during their stay. In order to be able to measure these activities and symptoms, we will use wireless sensors that sit bedside and smartwatches. The devices used will help us to obtain objective measurements of activities and symptoms. By participating, you can help to improve activity assessment for people with dementia in nursing homes, contributing to improved quality and treatment decisions.

Practical information and who is invited to participate: 

  • People with dementia, aged 65 and over, who have lived in a nursing home for longer than 1 year.
  • If you participate, you will be followed up by a research and nursing home team.
  • At the start of the study, we ask you and your primary contact questions.
  • We will collect sensor data with a small box that is installed in your room.
  • Furthermore, we ask you to wear a smartwatch on your arm for about 7 days.
  • The data collection is repeated every 6 months.
  • If you become seriously ill, sensor data must be collected continuously.
  • We will also meet your next of kin and ask for relevant information.
  • Study participation is voluntary! You can withdraw at any time without giving a reason.
