This is a feasibility study, designed to assess the acceptability of At Home Temperature Monitoring (AITM) by patients at high risk of diabetes foot ulceration. The investigation hopes to identify any problems with the study design before progressing to a full-scale evaluation, and will assess the ease of use of the technology and if there are any barriers to using this. Participants will be provided with an infrared camera and SMART phone and trained in how to use them. The participants will then be expected to capture images of both the plantar and dorsal aspects of their feet that will be sent to the research team for review. The two images will be captured once per day. The Intervention period will be 12 weeks. If a raised temperature is identified, the participant will be offered a face to face review appointment where they will receive podiatry treatment (if required), ulcer prevention advice and more detailed thermal imaging. Patient and health care professional (HCP) questionnaires will be used at the start and end of the study period to assess quality of life impact and device ease of use.

Device Feasibility - Completion
Participants successful completion of 12 weeks (percentage of all subjects who were enrolled in the study with ≥70% considered successful target (21 patients). This will assess if usage of the device on a daily basis over a specific period of time is practical
Time frame: 12 weeks
Device Feasibility - Withdrawal
Participants withdrawal (Percentage of all subjects who were enrolled in the study ≤30% considered successful target). A low withdrawal rate will demonstrate that usage of the device is practical over the time period
Time frame: 12 weeks
Device Feasibility - Compliance
No submission of images - i.e. no image submissions for 7-consecutive days on 2-occasions, generating 2-alerts over 12 weeks (absolute number of 'no submission' alerts). A lack of compliance with the study protocol will demonstrate low feasibility for regular device usage
Time frame: 12 weeks
Device Feasibility - Safety
Incidence of Serious adverse events (SAEs) and Adverse device reactions (ADRs)
Time frame: 12 weeks
Device Feasibility - Quality of life (QoL) utilising EQ-5D-5L instrument
Patient completion of EQ-5D-5L health utility score to obtain a health utility score at Baseline and at Week 12 (target 80% completion). (The EQ-5D-5L descriptive system comprises the same five dimensions as the EQ-5D-3L (MOBILITY, SELF-CARE, USUAL ACTIVITIES, PAIN / DISCOMFORT and ANXIETY / DEPRESSION), but each dimension now has five response levels: no problems, slight problems, moderate problems, severe problems, unable to/extreme problems. The respondent is asked to indicate his/her health state by checking the box next to the most appropriate response level for each)
Time frame: 12 weeks
Device Feasibility - Health Economics
Health care utilisation and costs. The podiatrists will keep a log of time spent checking images and additional appointments generated in response to alerts. Costs will be calculated using staff time x staff payment costs
Time frame: 12 weeks
Device Feasibility - Staff feedback on device use
A focus group meeting with podiatrists will be scheduled at the end of the participant data collection period to obtain qualitative data relating to device use.
Time frame: 12 weeks
Device Feasibility - Patient feedback on device use
Patient completion of User Questionnaire Form (Week 12) (target 80% completion)
Time frame: 12 weeks
