eHealth InfrastructureEnsure smooth network integration

Siemens eHealth Infrastructure-Components Grafik

The IT landscape of most clinical institutions is rather complex and heterogeneous. Furthermore, strict data security requirements have to be observed. eHealth Solutions make patient information seamlessly available across institutions while complying with national and international security standards. Its components can be individually implemented, depending on the need and the existing infrastructure of the clinical institution.


Local Node
The Local Node is a network node that is installed in a participating institution (or as central tenant) and connected to the local primary systems. It enables the participation in the network of the institution.

Community Node
A Community Node provides central services such as an MPI, a document register or an authorization system and connects the Local Nodes of the participating institutions to a health network (“affinity domain”).

Application Node
The Application Node provides the framework for a pool of different applications that can be placed on the network. This supports cross-institutional treatment as well as workflows.

  • Identification of patient through matching of master data and unique identifiers
  • Data exchange of patient-related documents, images between communication partners
  • Patient-centric search and retrieval of images and documents
  • Control of access rights
  • Full audit trail
  • Support of cross-facility processes

The eHealth standards-compliant IHE networking infrastructure provides the basis for the exchange of health-related data. The infrastructure consists of following components. Learn more by clicking on the links.

eHealth Infrastructure Components

The eHealth standards-compliant IHE networking infrastructure provides the basis for the exchange of health-related data.

The infrastructure consists of:

Siemens eHealth Master-Patient Index

Creating a cross-institutional MPI
eHealth Solutions allow several institutions with different clinical information systems or large healthcare enterprises with multiple patient identity sources to set up a shared Master Patient Index – fully based on IHE profiles and supporting HL7 v2 and v3. The generated Master Patient ID unifies identification and patient demographics.

Benefits at a glance:

  • Centralized access to healthcare data, produced in a heterogeneous healthcare environment with multiple sources for patient identification (Multi-HIS environment)
  • One index for all patient information, manage and monitor from a modern, web-based administration console
  • Opportunity to lower costs for clearing patient identification and demographics using intelligent and flexible matching algorithms


Siemens eHealth Electronic Health Record

One electronic patient record across institutions
With the EHR, several healthcare providers in a region or within a clinical enterprise can gain save access to the existing health data of a patient. It offers:


  • A fine-grained access control system to define user-dependent access rights for highest possible data security
  • Support of distributed data repositories and central index services such as MPI or document registry
  • Adaptors for easy connection based on HL7, DICOM, web service or IHE

Benefits at a glance:

  • Access to medical data of a patient, independent from the institution of treatment
  • Working in own primary system, which is connected with the network
  • Audit trail about transactions, which are transporting sensitive information
  • One channel for communication with other institutions
  • Very high security measures, interfaces fully follow IHE standards
  • One data exchange platform for several purposes of data exchange, extendable by cooperative care applications


Siemens eHealth Electronic Health Record Adapter Set OutlineOverview

A highly flexible health network
eHealth Solutions offer an out-of-the-box product for usually difficult interfacing tasks: Easily connect heterogeneous health systems to standardized and IHE-based EHR systems using different interface adaptors.


Benefits at a glance:

  • Seamless integration of own IT tools (like CIS, RIS, PACS, etc.) with cross-enterprise EHR systems.
  • Keep working in own system and access documents or images from other systems/care providers
  • Quick and simple connection to EHR systems even of different IHE vendors
  • Translation of interfaces (in and out), i.e. from HL7 v2 to v3, data validations, semantic standardizations of meta data, patient identifier handling


Siemens eHealth Enterprise Audit Repository

Audit trail data in one place
With EAR, eHealth Solutions support collecting audit tail messages from different IT systems (e.g. HIS, EMR, PACS, RIS, LIS) in one Audit Repository for data security and reporting purposes. It offers:


  • Full compliance with IHE ATNA Audit Repository and “Secure Node” requirements
  • Performant search mechanisms for user- or patient-based audit trails
  • A web-based analysis and reporting tool
  • Archiving of log entries, and more

Benefits at a glance:

  • Transparency, simple evidence, and proof in case of data security issues
  • Easy reporting on accesses over different IT systems in a hospital
  • Traceability of user- and patient-related actions
  • Increased awareness for data security in enterprise
  • Fulfill legal requirements
