Open Electronic Health Record Mechanism for Interoperable Cloud Performance and Confidentiality
Sadhula Srihari Reddy, Murali Mohan Vutukuru · 2025
The popularity of interoperable cloud environments can be attributed to the growing need for secure and effective administration of healthcare data. In order to guarantee interoperability, performance and privacy, OpenEHR—an open standard specification in health informatics is essential. This survey research uses OpenEHR technologies to investigate performance and privacy management issues in interoperable cloud environments. The main features of OpenEHR are covered, along with how it can be used in cloud contexts and how it affects the administration of medical data. Along with outlining the advantages and difficulties of utilizing OpenEHR in healthcare data management, the article also covers recent developments and research in this area. The study also addresses how OpenEHR 's standardized data models and access control methods might support effective data interchange while protecting patient privacy. Four EHR systems are compared in this study: Cleveland Clinic's Epic, HL7 FHIR, OPENEHR, and CDA. Although its implementation complexity is minimal, OpenEHR boasts significant levels of interoperability, data reuse, and customization possibilities. Although HL7 FHIR has modest implementation complexity and expense, it allows real-time data access and flexibility. Although CDA offers strong regulatory compliance, it is less flexible and requires more work when creating templates. Cleveland Clinic's Epic system has a high degree of maturity, strong community support, and complete regulatory compliance; but, it also has a high cost, restricted data reuse, and severe vendor lock-in.
