The FHIR Data Standard: How to achieve seamless interaction between patient data and the electronic patient file 

The paper-based documentation of clinical data will be replaced in 2021 in Germany: The electronic vaccination recordthe electronic maternity log or the electronic dental bonus booklet will be central components of the electronic patient file. This requires new digital infrastructures for the integration of clinical data and systems. 

The electronic patient file 

The electronic patient file will be introduced on January 1, 2021 in GermanyIn the future, the e-vaccination recordthe e-maternity log and the electronic dental bonus booklet for the check-up visit to the dentist will make paper-based documents unnecessary. The data documented in the electronic records will be stored centrally in the electronic patient file. With the corresponding consent of the insured person, the status can be viewed and completed on site at the doctor’s office or the clinic.  

Why standardisation? 

Standardising patient files simplifyies all processes that require cross-institutional cooperations between medical service providers, drug supply, nursing care and cost units. 

The cost savings achieved are significant: The use of a uniform, internationally standardised procedure for the transmission of information replaces the implementation of different infrastructures and data formats, such as those used for service accounting. 

Also, data loss, which often occurs using paper-based documents, is no longer an issue. There are no documentation gaps in the event of visiting different doctor’s offices and also, time-consuming follow-up entries can be avoided. 

What is FHIR? 

The FHIR standard (Fast Healthcare Interoperability Resources) enables secure data exchange between software systems and thus plays a central role in the introduction of the electronic patient file. Data formats are exchanged via interface. This means that health-related data provided by patients, e.g. by using health apps, can be processed on mobile devices such as smartphones or tablets and integrated into existing systems. Therefore, FHIR represents the basis of digital data transmission and consolidation, which are essential for the further development of the digitalisation of healthcare.

CSIRO Ontoserver

Terminologieserver, der SNOMED CT-, AMT-, LOINC und FHIR-basierte Code-Systeme in FHIR-Infrastrukturen zur Verfügung stellt

With the Healex Clinical Integration Hub (CIH), Healex presents a seamless FHIR infrastructure for the complete integration of clinical data and systems. 

The Clinical Integration Hub includes the Vonk FHIR Server, an immediately integrated and ready-to-use FHIR server that can be used for clinical documentation, patient portals and mobile apps as well as clinical trials that include studies with pseudonymized data. 

Vonk FHIR plug-ins allow the customised integration of the Vonk FHIR Server into proprietary system architecture and therefore executing user-defined operations within the FHIR framework. 

The FHIR mapper allows clinical data to be integrated into ones own FHIR infrastructure. In addition, mapping of different data formats and ensuring data quality is possible. 

The CSIRO Ontoserver is a FHIR-based clinical terminology server. It uses a fast, prefix-based search algorithm to ensure that content can be found easily. The Healex Clinical Integration Hub offers a comprehensive FHIR infrastructure for digital documentation and transmission of patient data and the upcoming electronic patient file.
