Thermal Imaging in Old and Frail in the Community

Study Overview
=================
Brief Summary
-----------------
This study aims to test whether infrared thermal imaging using a non-touch, non-ionising, thermal camera system is feasible and reliable as an independent technique for thermal comfort assessment in older people and frail older people living in a care home and with or without mild cognitive impairment.

Detailed Description
-----------------
Thermal comfort (TC) is a complex interaction involving physiological, social, cultural and clothing factors. In hospital and in care homes, health-issues (frailty, dementia, immobility) can affect a person's perception of TC. In the UK 18,000 care homes provide living-communities for approximately 400,000 people. Many are old/frail and vulnerable to indoor chilling. A quality indicator for a good ''home'' environment is related to TC. However, in multiplyoccupied rooms TC varies between individuals. The challenge in health-assessment is in identifying ''uncomfortable'' residents (too hot/too cold). As TC is a subjective perception; a carer cannot reliably predict TC in another person. The objectives are to use infra-red thermal imaging (IRTI) to 'see' the body temperature map, to demonstrate prevalence of TC/thermal discomfort, to demonstrate whether there is correspondence/dissociation between TC self-report and IRTI-measured body/extremity (hand) temperature. The study aims to establish if TC can be predicted by an independent non-invasive imaging device Expected achievements are a two-way pathway to health impact: identification of eligible adults via NHS intermediary care- and awaiting care home residency expert guidance and collaboration with NHS partners translation of results from community to NHS setting e.g. stoke/aged care medicine for improved thermal care on the hospital wards Longer-term the expected achievement (5-7 years)-working with NHS colleagues and design/product development teams is expected to lead towards a commercialisation pathway.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Thermometer | Body Temp: degrees whether an older persons perceptions about thermal comfort is best predicted by their body temperature from the thermometer in Degrees Centigrade. Their temp will be compared to their self reported thermal comfort. | Baseline | 
| Thermal Imaging comparison | whether an older persons perceptions about thermal comfort is best predicted by the image that the thermal camera provides (known as a thermal map) along with the data (temperature values) that can be extracted from the thermal image particularly over the area of interest which in this study is the hands and forearm. The thermal image will be compared to self-reported thermal comfort. | Baseline |
