[Evaluation of the User Experience of GER-e-TEC, a Geriatric Telemonitoring Tool for Risk Prevention]

Population aging leads to an increase in emergency hospitalizations among older adults, particularly those living in nursing homes (EHPAD). To help prevent such hospitalizations, the GER-e-TEC device was developed to provide home-based medical telemonitoring by collecting various physiological parameters. The aim of this study was to evaluate the user experience (UX) of the device among patients, caregivers, and healthcare professionals. The study included nine patients, nine healthcare professionals, and ten caregivers who had used GER-e-TEC for at least four weeks. UX was assessed using the AttrakDiff questionnaire, which measures both pragmatic and hedonic qualities of the device. The usability of the MyPredi application was evaluated with the DEEP questionnaire, while older adults' acceptance of technologies was assessed with the S-STAM scale. Descriptive statistical analyses and qualitative feedback were also used to complement the evaluation. The study revealed an overall positive UX. Patients and caregivers appreciated the user-friendliness and relevance of the device, although heterogeneous responses were observed. Healthcare professionals expressed concerns about usability, particularly the lack of clear guidance on procedures to follow in the event of an alert. The MyPredi application was generally well received, although some caregivers reported technical difficulties. GER-e-TEC was generally well accepted, especially by patients who found it reassuring. However, improvements are needed, particularly regarding the clarity of procedures and communication between healthcare professionals and the coordination unit. Despite these limitations, the device appears effective in improving home medical monitoring and preventing avoidable hospitalizations.
