A reference architecture for healthcare supportive home systems from a systems-of-systems perspective

Abstract : Population ageing has been taking place all over the world, being estimated that 2.1 billion people will be aged 60 or over in 2050. Healthcare Supportive Home (HSH) Systems have been proposed to overcome the high demand of remote home care for assisting an increasing number of elderly people living alone. Since a heterogeneous team of healthcare professionals need to collaborate to continually monitor health status of chronic patients, a cooperation of pre-existing e-Health systems, both outside and inside home, is required. However, current HSH solutions are proprietary, monolithic, high coupled, and expensive, and most of them do not consider their interoperation neither with distributed and external e-Health systems, nor with systems running inside the home (e.g., companion robots or activity monitors). These systems are sometimes designed based on local legislations, specific health system configurations (e.g., public, private or mixed), care plan protocols, and technological settings available; therefore, their reusability in other contexts is sometimes limited. As a consequence, these systems provide a limited view of patient health status, are difficult to evolve regarding the evolution of patient’s health profile, do not allow continuous patients monitoring, and present limitations to support the self-management of multiple chronic conditions. To contribute to solve the aforementioned challenges, this thesis establishes HomecARe, a reference architecture for supporting the development of quality HSH systems. HomecARe considers HSH systems as Systems-of-Systems (SoS) (i.e., large, complex systems composed of heterogeneous, distributed, and operational and managerial independent systems), which achieve their missions (e.g., improvement of patients’ quality of life) through the behavior that emerges as result of collaborations among their constituents. To establish HomecARe, a systematic process to engineer reference architectures was adopted. As a result, HomecARe presents domain knowledge and architectural solutions (i.e., architectural patterns and tactics) described using conceptual, mission, and quality architectural viewpoints. To assess HomecARe, a case study was performed by instantiating HomecARe to design the software architecture of DiaManT@Home, a HSH system to assist at home patients suffering of diabetes mellitus. Results evidenced HomecARe is a viable reference architecture to guide the development of reusable, interoperable, reliable, secure, and adaptive HSH systems, bringing important contributions for the areas of e-Health, software architecture, and reference architecture for SoS.
