Standardized Medical Data Interoperability: Explaining Diverse Interfaces like HL7, GDT, and FHIR
Praxissoftware Anbindung Arztpraxis GDT HL7 FHIR REST - AnaBoard
Summary
This article explains multiple standardized interfaces used to achieve data exchange between electronic health records and external systems. It details international communication standards like HL7, as well as Germany-specific protocols such as GDT (Gerät-Daten-Transfer) and VDDS, illustrating the technical aspects of medical data interoperability.
Details
This article introduces several standardized specifications for connecting hospital information systems with practice management software. First, it focuses on HL7 (Health Level Seven), an international electronic communication standard that enables the exchange of patient data and clinical findings between various healthcare systems like KIS and LIS, thereby improving automation and efficiency. Technically, this involves exchanging messages via protocols such as TCP/IP or HTTP. It also covers GDT (Gerät-Daten-Transfer), a standard widely used in German practices. This protocol specializes in transferring data from medical devices to practice systems, characterized by its manufacturer independence and ability to automatically integrate test results into the electronic patient record. Furthermore, for dental fields, VDDS (Verband Deutscher Dental-Software Unternehmen e.V.) has established unique interfaces that standardize the exchange of clinical records, images, and billing data. Collectively, these standards solve information sharing challenges in medical settings, forming the foundation for interoperability necessary for realizing electronic patient records (ePA). The text demonstrates how specialized technical solutions like HL7 and GDT address specific integration needs across various systems.
