Multi-part quality evaluation of a customized mobile application for monitoring elderly patients with functional loss and helping caregivers.

BACKGROUND: The challenges faced by caregivers of the elderly with chronic diseases are always complex. In this context, mobile technologies have been used with promising results, but often have restricted functionality, or are either difficult to use or do not provide the necessary support to the caregiver - which leads to declining usage over time. Therefore, we developed the Mobile System for Elderly Monitoring, SMAI. The purpose of SMAI is to monitor patients with functional loss and to improve the support to caregivers' communication with the health team professionals, informing them the data related to the patients' daily lives, while providing the health team better tools. METHOD: SMAI is composed of mobile applications developed for the caregivers and health team, and a web portal that supports management activities. Caregivers use an Android application to send information and receive care advice and feedback from the health team. The system was constructed using a refinement stage approach. Each stage involved caregivers and the health team in prototype release-test-assessment-refinement cycles. SMAI was evaluated during 18 months. We studied which features were being used the most, and their use pattern throughout the week. We also studied the users' qualitative perceptions. Finally, the caregiver application was also evaluated for usability. RESULTS: SMAI functionalities showed to be very useful or useful to caregivers and health professionals. The Focus Group interviews reveled that among caregivers the use of the application gave them the sensation of being connected to the health team. The usability evaluation identified that the interface design and associated tasks were easy to use and the System Usability Scale, SUS, presented very good results. CONCLUSIONS: In general, the use of SMAI represented a positive change for the family caregivers and for the NAI health team. The overall qualitative results indicate that the approach used to construct the system was appropriate to achieve the objectives.

The UFRJ-UERJ group: interdisciplinary virtual reality experiments in neuropsychiatry.

This paper describes the research lines of an interdisciplinary group composed by two government universities in Rio de Janeiro. The first research line, a Virtual Environment for testing the acceptance of Virtual Reality equipment by schizophrenia patients, has stimulated a growing interest in this area in the country and abroad. The second research line, in progress now, develops a virtual environment to improve the learning abilities of children with Attention-Deficit and Hyperactivity Disorder (ADHD). Another study is related to the use of Virtual Reality in the cognitive treatment of common city phobias, beginning with the reproduction of some tunnels of our city to treatment of claustrophobic patients. The last of the research lines in progress in this group develops a virtual square for stimulating autistic patients.
