Details
This document details the technical specification for a new FHIR search parameter, 'EEMPIExternalSystemPresence,' related to Estonia's electronic health record system. The purpose of this parameter is to confirm the existence of a patient across multiple distinct data sources that healthcare institutions might connect with. This capability is crucial for accurately identifying the same individual across different systems, thereby enhancing interoperability and ensuring consistency in patient identification. The parameter is defined as `external-system-presence` and utilizes a specific token for implementation. Based on FHIR 5.0.0 and provided as version 1.5.0, this specification strengthens standard identifier lookup mechanisms within FHIR. Such technical updates are vital for preventing critical issues like duplicate or missing patient IDs, forming a foundation for safer and more reliable healthcare information exchange globally.
