ADVANCED HEALTHCARE SYSTEM USING E-HEALTH & M-HEALTH IN CLOUD & MOBILE ENVIRONMENTS

Large-scale distributed systems, such as e-healthcare, are difficult to develop due to their complex and decentralized nature. The service oriented architecture facilitates the development of such systems by supporting modular design, application integration and interoperation, and software reuse. This article describes a distributed e-healthcare system that uses the service-oriented architecture as a means of designing, implementing, and managing healthcare services. We present a cloud-based approach for the design of interoperable electronic health record (EHR) systems and the concept of “m-health” is defined in transactions as “mobile computing, medical sensor, and communications technologies for healthcare.” We propose an EHR system?cloud health information systems technology architecture (CHISTAR) that achieves semantic interoperability through the use of a generic design methodology which uses a reference model that defines a general purpose set of data structures and an archetype model that defines the clinical data architecture. The m-health concept has become one of the key technological domains that reflect the key advances in remote healthcare and e-health systems. The m-health is currently bringing together major academic research and industry disciplines worldwide to achieve innovative solutions in the areas of healthcare delivery and technology sectors. The new and novel concept of 4G health and 5G technology that represents the long-term evolution of mhealth.
