Architectural design of national evidence based medicine information system based on electronic health record.

Background: The global implementation of Electronic Health Records has significantly enhanced the quality of medical care and the overall delivery of public health services. The incorporation of Evidence-Based Medicine offers numerous benefits and enhances the efficacy of decision-making in areas such as prevention, prognosis, diagnosis, and therapeutic approaches.

Objective: The objective of this paper is to propose an architectural design of an Evidence-Based Medicine information system based on the Electronic Health Record, taking into account the existing and future level of interoperability of health information systems in Greece.

Implementation of a nationwide electronic health record (EHR).

Purpose The purpose of this paper is to identify the best practices applied during the implementation process of a national electronic health record (EHR) system. Furthermore, the main goal is to explore the knowledge gained by experts from leading countries in the field of nationwide EHR system implementation, focusing on some of the main success factors and difficulties, or failures, of the various implementation approaches. Design/methodology/approach To gather the necessary information, an international survey has been conducted with expert participants from 13 countries (Denmark, Austria, Sweden, Norway, the UK, Germany, the Netherlands, Switzerland, Canada, the USA, Israel, New Zealand and South Korea), who had been playing varying key roles during the implementation process.

Integrated Nationwide Electronic Health Records system: Semi-distributed architecture approach.

Background: The integration of heterogeneous electronic health records systems by building an interoperable nationwide electronic health record system provides undisputable benefits in health care, like superior health information quality, medical errors prevention and cost saving.

Objective: This paper proposes a semi-distributed system architecture approach for an integrated national electronic health record system incorporating the advantages of the two dominant approaches, the centralized architecture and the distributed architecture.

Methods: The high level design of the main elements for the proposed architecture is provided along with diagrams of execution and operation and data synchronization architecture for the proposed solution.
