Usabilidade do sistema inteligente GerontoIA para avaliação multidimensional de pessoas idosas na Atenção Primária a Saúde

Abstract

The increase in the elderly population is a global phenomenon that has drawn the attention of researchers and healthcare professionals in recent years. Therefore, there is a need to perform multidimensional assessments of elderly individuals in the context of Primary Health Care. To this end, technological solutions are required to assist in this assessment. Objective: To validate the GerontoIA Intelligent System for the multidimensional assessment of elderly individuals. Method: This is a methodological study aimed at validating the GerontoIA software through usability evaluations with researchers and experts using an online form based on Nielsen's Heuristics and the System Usability Scale. Results: The overall mean and standard deviation of the Heuristics reached a score of 4.5±0.56, with the best-rated heuristics being "User control and freedom" (4.9±0.38) and "Consistency and standards" (4.81±0.31); and the worst-rated was "System status visibility," with an average of 4.16±0.98. Regarding the overall severity rating, the score was 1.9 ~ 2 indicating that issues can be addressed with low priority for repair. A mean SUS score of 90 was observed, indicating excellent satisfaction (acceptable range), with the lowest score ranging from 80 (excellent) to 95 (best imaginable). After the usability evaluation by experts, the team gathered to make improvements to the software, prioritizing user experience regarding its usability. Final considerations: GerontoIA has acceptable usability measured by two relevant metrics. As it is a prototype, it requires improvements, but it is potentially usable by the target audience.
