Standardized Electronic Medical Records: Transformation into a Connected Healthcare Information Infrastructure via HL7 FHIR and API Linkage
【システム開発視点】標準型電子カルテとは何か｜HL7 FHIR・API連携・クラウド型SaaSを歯科 ...
Summary
The standardized electronic medical record is redefined not as a single product, but as a connected healthcare information infrastructure. It requires a design philosophy that utilizes cloud SaaS and standards like HL7 FHIR to achieve flexible linkage from minimal core functions to external services.
Details
This article analyzes the concept of standardized electronic medical records from a system development perspective. The model is shifting away from traditional single-product systems that 'encapsulate all functions' toward a design where there is a 'minimal core function' operated on a cloud basis, and 'peripheral functions extended via API.' Key technologies driving this change include HL7 FHIR, an international standard acting as a common language for exchanging medical information between different vendors and products. Operationally, the shift from on-premise to cloud SaaS is becoming standard, emphasizing standardization of maintainability, scalability, and cost efficiency. For dental system development, it is crucial to consider future linkage while respecting unique operational characteristics. Beyond merely implementing APIs, comprehensive design must cover entire operational flows, including authentication, authorization, and data integrity.
