Improving Interoperability in Healthcare: A User-Friendly International Standard Data Conversion Framework

Standardization helps improve supplier compatibility, interoperability, repeatability, security, and quality. The SARS-CoV-2 pandemic has highlighted the need for global requirements regarding the interoperability of healthcare information. Currently, Taiwan still relies on the second edition of the Clinical Document Architecture (CDA) as the standard for exchanging medical data, which was formulated 17 years ago. There is currently no unified specification for medical data transformation or review mechanism in place. To address this issue, it is necessary to adopt the widely used international healthcare data exchange standard, Fast Healthcare Interoperability Resources (FHIR), established by Health Level Seven International (HL7). The aim of this research is to simplify the mapping of medical data and convert it into the international FHIR format, enabling rapid data transformation. Additionally, an interface will be designed to meet user habits and requirements. By utilizing common clinical data structures in Taiwan as an example, a mechanism for data conversion and verification will be developed to achieve fast health data exchange and enhance interoperability in the healthcare field.
