Empowering Aging in Place: An innovative Web-Based Simulation Approach for Enhancing Domestic Risk Evaluation Among Older People

Context: Faced with the growing challenge posed by the aging population, preserving autonomy at home is now essential. To achieve this goal, it is necessary to identify and prevent domestic risks associated with aging, using innovative and inclusive solutions. In this regard, the web platform PREVIE has been developed to provide contextualized phenotypes of cognitive difficulties in older individuals, based on the simulation of activities of daily living. – Method: Two participants aged 69 and 70 were included in the study. They underwent six sessions over three weeks, using the web platform PREVIE on a tablet. Pre- and post-test assessments included measures of self-efficacy, computer anxiety, expectations, and technology acceptance. The methodology integrated learning phases, unassisted application, and assisted application, with continuous performance assessment. – Results: A significant improvement in participants' performances over the sessions was observed. Self-efficacy, expectations, and the intention to use the platform also evolved positively. The types of errors varied, highlighting the platform's sensitivity to cognitive changes in a simulated environment. – Conclusion: The results of this case study suggest that the PREVIE web platform offers an accessible approach to assess cognitive difficulties in simulated activities of daily living, which can subsequently be used as a basis for understanding home risks in older individuals. Current findings suggest that it is feasible to explore the potential of digital phenotyping in older adults, in addition to conventional household risk assessments. This approach opens the door to earlier, tailored interventions for this demographic group.
