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.
This paper presents a comprehensive approach to describe, deploy and adapt component-based applications having dynamic non-functional requirements. The approach is centered on high-level contracts associated to architectural descriptions, which allow the non-functional requirements to be handled separately during the system design process. This helps to achieve separation of concerns facilitating the reuse of modules that implement the application in other systems. Besides specifying non-functional requirements, contracts are used at runtime to guide configuration adaptations required to enforce these requirements. The infrastructure required to manage the contracts follows an architectural pattern, which can be directly mapped to specific components included in a supporting reflective middleware. This allows designers to write a contract and to follow standard recipes to insert the extra code required to its enforcement in the supporting middleware.
Objective: To analyze the perceptions of caregivers and health professionals about a mobile application used for the caring and social support of people with dementia. Method: A qualitative study was performed on the experience of implementing a Mobile Care System for Older Adults (Sistema Móvel de Assistência ao Idoso, SMAI) in the routine of caregivers of people with dementia, treated at an outpatient clinic for cognitive disorders. Data were obtained through the application of questionnaires about the characteristics of caregivers and the Zarit scale to assess the level of burden. An Activities of Daily Living Questionnaire (ADLQ) was applied for functional evaluation. The perception of caregivers and professionals were collected through the audio recording of focus groups and analyzed according to the thematic-categorical analysis technique. Results: Twenty caregivers and five health professionals participated in the focus groups. Categories that emerged from the study revealed themes related to users’ experiences, communication, medication management, feelings of caregivers, patient management strategies, impact of dementia on caregivers’ lives, illness of caregivers and application evaluation. Conclusion: Interventions using mobile applications can help improve communication and social support in the care of dementia. The experience with the SMAI and its applications represented an innovative opportunity for both family caregivers and healthcare professionals.
This paper presents an approach to describe, deploy and manage component-based applications having dynamic functional and non-functional requirements. The approach is centered on architectural descriptions and associated high-level contracts. Besides specifying non-functional (or QoS) requirements, these contracts are used to guide architecture customizations required to enforce the requirements. The infrastructure required to manage the contracts follows an architectural pattern, which can be directly mapped to specific components included in a supporting reflective middleware. This approach allows designers to write a contract and to follow a standard recipe to insert the extra code required to its enforcement in the supporting middleware.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
