Smile CDR core functions
Interoperable data management
Storage of clinical information according to HL7 FHIR (R4) - version-safe, traceable, usable for documentation, analysis and decision support.
Integration & interfaces
Connection via HL7 v2 or REST APIs. nursIT ensures correct processing and semantic consistency – including embedding of unstructured content (e.g. PDFs from MDM).
Terminologies & semantics
Supports SNOMED CT, LOINC and ICD-10 – comprehensible, comparable and analyzable across systems.
Security & Governance
Role-based access management, central authentication, complete logging – on premise, GDPR-compliant.
Application scenarios in clinics and research
With Smile CDR, clinics create the basis for an interoperable and sustainable data architecture for modern care. At the same time, Smile CDR creates a standardized database for clinical research, quality assurance and data-driven analyses – always under the full control of the clinic.
Central data platform
Structured recording, storage and provision of health data - as an integral part of digital treatment and care processes.
Integration of heterogeneous IT
Standardized interfaces connect HIS, MDM and specialist systems to form a consistent database.
Supply, research, analysis
Consolidated, locally stored information for quality assurance, process control and studies - without external cloud services.
Basis for data-driven applications
Foundation for real-time monitoring, clinical decision support and AI analysis. Allows customized FHIR front ends from simple dashboards to complex applications such as careIT for use directly at the point of care.
Why clinics rely on Smile CDR
As a database for our KAS careIT or as a stand-alone platform, Smile CDR connects systems, harmonizes information and ensures the exchange and reusability of clinical data across system boundaries - for long-term usable health data.
Interoperable according to international standards
Supports FHIR, HL7, SNOMED CT and LOINC – manufacturer-independent and ISiK-compliant.
Full data sovereignty and security
Local processing and storage – GDPR-compliant and with transparent access control.
Seamless integration into existing systems
Integrate Smile CDR into your IT structure without major changes – with support from nursIT experts.
Open for innovation and further development
Modular platform for future digital and AI-based applications.
Frequently asked questions about FHIR CDR
-
What is FHIR?
FHIR (Fast Healthcare Interoperability Resources) is an international HL7 standard for the structured exchange of healthcare data.
FHIR uses modern web technologies (e.g. REST APIs, JSON, XML) and creates a future-proof basis for digital patient records, clinical data platforms and interoperable software solutions in the healthcare sector.
-
What is the difference between HL7 V2.x and HL7 FHIR?
HL7 v2 has been used worldwide for the exchange of medical data for many years, but is technically complex and often interpreted differently.
HL7 FHIR works with resource models and web technologies and thus enables a more flexible, better interoperable data exchange - ideal for modern hospital IT, clinical data repositories and national platforms.
-
What is Smile CDR?
Smile CDR is a Clinical Data Repository (CDR) that is fully based on the HL7 FHIR standard and securely stores, harmonizes and provides interoperable clinical data.
It serves as a central data platform for care, research and AI-supported analyses and forms the basis for modern, interoperable healthcare IT.
-
What distinguishes a FHIR-CDR from normal clinical databases?
A FHIR-CDR:
-
Stores data in a standardized and structured way,
-
integrates information from different clinical systems,
-
enables interoperable access via FHIR APIs,
-
supports analysis, reporting and AI processing.
In contrast to proprietary individual databases, this creates a standardized, future-proof data platform.
-
-
Can existing HL7 v2 interfaces continue to be used?
Yes, existing HL7 v2 interfaces can continue to be used and integrated into a modern FHIR architecture.
-
What does ISiK-compliant mean?
ISiK (Interoperability Standard for Information Systems in Hospitals) defines binding gematik requirements for data exchange in hospitals. ISiK-compliant means that these requirements are met.
This includes standardized interfaces, FHIR support and defined security mechanisms. ISiK-compliant systems are future-proof and designed for modern hospital IT architectures.
-
What are SNOMED CT, LOINC and ICD-10 and how do they complement FHIR?
SNOMED CT, LOINC and ICD-10 are international terminologies and classifications that standardize medical terms. FHIR defines the structure and transfer of the data - together they ensure semantically clear, interoperable information.
-
SNOMED CT: clinical terminology for the precise description of medical concepts (diagnoses, findings, measures).
-
LOINC: Standard for laboratory and measured values such as blood parameters or vital data.
-
ICD-10: Classification system for coding diagnoses for documentation, statistics and billing.
In combination with FHIR, a basis for high-quality, analyzable data is created - essential for digital care, research and AI-supported analyses.
-
-
Does Smile CDR meet European requirements?
Yes, Smile CDR can be operated entirely on premise, is GDPR-compliant and can be adapted to national legal frameworks in Europe.
This makes the platform ideal for clinics and healthcare networks in Germany, Austria, Switzerland and the EU that value data sovereignty and legally compliant processing.
-
How does nursIT support the introduction of the FHIR CDR?
nursIT provides hospitals with comprehensive support in the planning, implementation and operation of a FHIR-CDR – from architecture to go-live.
