Plain English Summary
Background and study aims
Over 850,000 people living in the UK have been diagnosed with dementia. This number is expected to double over the next 20 years. People with dementia receive little routine monitoring by health care providers, with this responsibility falling to their family and friends. This means that, despite best efforts, there can be delays in picking up health issues such as urinary tract infections, falls or problems with mobility which may result in the person with dementia requiring more care from family and friends or being admitted to hospital. We have developed an Internet of Things (IoT) technologies system – using connected environmental sensors and healthcare devices – to monitor the person with dementia in their own home. This system is known as the TIHM for Dementia System of Care, and has been tested previously in a randomised controlled trial (ISRCTN46184518). Installed in the person with dementia’s home, it gathers information from the environment and connected healthcare devices (e.g. blood pressure monitor, weighing scales). This information is fed into a predictive algorithm which is designed to alert a team of clinicians monitoring the system 24 hours a day, seven days a week to any health issues the person with dementia may have. This team will then telephone the person with dementia or their carer to offer healthcare advice and support. This study aims to refine and evaluate the TIHM for Dementia System of care ready for wide use.
Who can participate?
People with dementia can participate along with their live-in or nominated carer if they are currently living in the community and receiving 10 or more hours per week of home care. Persons with dementia need to be aged 50 years or older and have a confirmed diagnosis of dementia (any type) and meet all other study inclusion criteria.
What does this study involve?
Participants will use the TIHM for Dementia System of Care for 6 months. This will involve the person with dementia being remotely-monitored in their home. Most of this monitoring will take place automatically, however the person with dementia and their carer may be asked to also take measurements, such as blood pressure, temperature and pulse. People with dementia and their nominated carers will be asked to complete some questionnaires at the beginning, middle (after 3 months) and end (at 6 months) of the study. They may also be invited to take part in an interview with a researcher about their experience of using the system; these will take place at the middle and end of the study. After using the TIHM for Dementia System of Care for 3 months and as a result of feedback from the questionnaires and interviews, the technologies installed in the person with dementia’s home may be reviewed and changed. Participants will then continue to use TIHM for Dementia for the remaining 3 months.
What are the possible benefits and risks of participating?
There is the opportunity to help improve current health care and support for people with dementia and their carers by helping to refine and evaluate a novel health monitoring and management system. Participants will also benefit from the additional continuous healthcare support the system provides.
Taking part in this study presents minimal risk; however, the TIHM for Dementia System of Care is an experimental system. People with dementia and their carers may find it intrusive to have sensors in their home and difficult or time-consuming to use devices. The system does not replace usual care and participants will be asked to contact their standard care provider (e.g. GP or A&E department) should they feel the need to do so.

This study uses the TIHM for Dementia System of Care, an Internet of Things (IoT) health monitoring and integrated management system. This system gathers information about the person with dementia through environmental sensors installed in their home and devices which monitor their daily activity and vital signs (e.g. GPS tracker, blood pressure monitor, thermometer, weighing scales). The IoT relays this information to a dedicated monitoring team through a computer-based alert system, which uses machine learning algorithms to provide the team with actionable-information and alerts for health and social care concerns. The monitoring team then contacts the patient and/or their carer to offer advice. Dementia Navigators also provide support for non-emergency issues. Patients are monitored by the TIHM for Dementia system 24 hours a day, seven days a week for their six months of participation.
Primary outcome measure
The composition of an optimised TIHM for Dementia System of Care solution based on:
1. Direct cost: Data on service use and patterns of unpaid care and support provided by families and friends will be recorded by a modified version of the Client Service Receipt Inventory (CSRI). Costs will be attributed to service use using NHS reference costs and unit costs from the Personal Social Services Research Unit (PSSRU, www.pssru.ac.uk). This will be assessed at the baseline and after 3 and 6 months
2. Service-use data, collected via a modified CSRI at the baseline and after 3 and 6 months
3. System performance, captured in real-time through data captured by the system itself on alerts related to technical performance
4. User-acceptability, assessed using an investigator designed tool developed based on the TAM at the baseline and after 3 and 6 months
Secondary outcome measures
The following are assessed at the baseline and after 3 and 6 months:
1. Incidence of A&E attendance, assessed using a modified version of the Client Service Receipt Inventory (CSRI)
2. Duration of hospital stay, assessed using a modified version of the Client Service Receipt Inventory (CSRI)
3. Incidence and severity of neuropsychiatric symptoms experienced by the person with dementia (PwD), assessed using the Neuropsychiatric Inventory–Questionnaire (NPI)
4. Incidence of urinary tract infections, agitation and falls experience by the PwD, assessed using a modified version of the Client Service Receipt Inventory (CSRI)
5. Health Related Quality of Life (HR-QoL) of the PwD, assessed using:
6. HR-QoL of carers, assessed using the EQ-5D-5L
7. Carer burden, assessed using the Zarit Burden Interview
8. Technology acceptance, assessed using an investigator-developed tool
