C Nugent, S O’Neill, M Donnelly, L Galway, M Beattie, S McClean, B Scotney
2. Dementia
• Dementia is a progressive, disabling, chronic
disease.
• 28 million people suffer from dementia worldwide.
• By 2030 the numbers are expected to double and
by 2050 they are expected to triple (Prince 2010).
• The costs of care associated with those suffering
from dementia were estimated at £400bn in 2010.
• Typical symptoms include impairments of
memory, thought, perception, speech and
reasoning.
• It is also common to witness changes in personality
and behaviour in addition to exhibit symptoms of
depression, apathy and aggression.

8. User Recruitment
• Participants were recruited by clinical research staff at the Memory
Clinic, Belfast City Hospital.
• Inclusion criteria:
– recorded as having mild dementia (MMSE >18),
– who lived alone and/or with a wiling carer able to record video
messages.
• Both patient and carer were involved in the informed consent
procedure.
• Baseline measurements of cognition were made based on MMSE and
the Disability Assessment for Dementia was used for functional ability.
• Pre and post evaluation questionnaires were administered by a research
nurse via face-to-face interviews.

Analysis of Results following evaluations
13. Analysis of post evaluation
questionnaires
• Overall the feedback from the participants and carers (based on set of 30
questions post evaluation) was positive:
– It supported reminders for their necessary tasks.
– The phone was easy to use.
– The phone interface and button size was very usable.
• Only 1 participant wore the phone around their neck others felt it was too
heavy.
• There was reported embarrassment about the reminder being delivered in
public.
• When asked about WTP, all dyads agreed that they would pay for the
service.
14. Analysis of post evaluation
questionnaires
• Negative Comments
“It didn't do anything, I didn't hear the messages.”
“It was too much she couldn't manage it and got frustrated, she kept
trying to listen like a phone to her ear” (Carer)
• Positive Comments
“Reminders very good especially re medication in middle of day.”
“useful prompt, took time to get used to it, only getting real hang of it
now”
15. Challenges
• Internet access (Broadband / Dongle)
• Personalisation
– Level of detail shown on screen and on
documentation
– Mode of reminder delivery (text, video)
• Data Management
– Heartbeat
– Activity / Acknowledgments
– Battery level
• Compliance
– Compliance Assessment (Sensorised Environment)
– Feedback Management
16. Conclusions
• Although data was limited with 4 participants, a
useful insight has been gained into the overall
utility of the system. (Long duration and recording
of video messages.)
• Varying levels of personalisation should be offered.
• Value the importance of technical framework to
support deployments.
• Support by carer is correlated with success of using
the device.
• Consider factors affecting technology adoption.
