Interaction of the HCM system with existing
systems
Necessary interfaces for integration
Well Integrated: HCM in the
Hospital IT Landscape
The HCM concept is based on the idea of centralized, uniform management
of medical data. Wherever centralization is required, integration is a must.
In practical terms, this means that an HCM system will only work if it integrates
itself seamlessly and deeply into the existing IT architecture. Figure 6.1
gives an overview of various IT systems in healthcare facilities and how an HCM
system integrates itself within the facility.
The Thing about Interfaces
Receiving and retrieving images and documents from other clinical systems is
only half the battle in an HCM context. After all, data can also undergo subsequent
alterations. And, of course, these alterations must not be lost when the data
is transferred to other systems. They must at least be carried out in the HCM system,
but preferably also within the subsystems. Both HL7 and IHE XDS already
provide for change management in their messages and transactions. In DICOM,
the alteration of data is not originally defined; however, it is introduced via the
IHE IOCM profile.
HL 7 FHIR: Interface of the future. For some time now, the HL7
standard has been evolving towards a new communication standard
called
HL7 FHIR (Fast Healthcare Interoperability Resources). Similar
to the HL7 standard of version 2 and 3, which has been used for many
years, this standard is specifically intended to support data exchange
