This part of ISO 12967 specifies the fundamental characteristics of the information model to be implemented by a specific architectural layer (i.e. the service architecture) of the information system to provide a comprehensive and integrated storage of the common enterprise data and to support the fundamental business processes of the healthcare organization, as defined in ISO 12967-1.

The information model is specified without any explicit or implicit assumption on the physical technologies, tools or solutions to be adopted for its physical implementation in the various target scenarios. The specification is nevertheless formal, complete and non-ambiguous enough to allow implementers to derive an efficient design of the system in the specific technological environment that will be selected for the physical implementation.

This specification does not aim at representing a fixed, complete, specification of all possible data that can be necessary for any requirement of any healthcare enterprise. It specifies only a set of characteristics, in terms of overall organization and individual information objects, identified as fundamental and common to all healthcare organizations, and that is satisfied by the information model implemented by the service architecture.

Preserving consistency with the provisions of this part of ISO 12967, physical implementations allow extensions to the standard information model in order to support additional and local requirements. Extensions include both the definition of additional attributes in the objects of the standard model, and the implementation of entirely new objects.

Also, this standard specification is extensible over time according to the evolution of the applicable standardization initiatives.

The specification of extensions is carried out according to the methodology defined in ISO 12967-1:2019, Clause 7, "Methodology for extensions".

HISA specifies fundamental requirements for 'information infrastructure' and healthcare specific ‘service architecture’.

This part of ISO 12967 specifies the fundamental characteristics of the computational model to be implemented by a specific architectural layer of the information system (i.e. the service architecture) to provide a comprehensive and integrated interface to the common enterprise information and to support the fundamental business processes of the healthcare organization, as defined in ISO 12967-1. The computational model is specified without any explicit or implicit assumption about the physical technologies, tools or solutions to be adopted for its physical implementation in the various target scenarios. The specification is nevertheless formal, complete and non-ambiguous enough to allow implementers to derive an efficient design of the system in the specific technological environment which will be selected for the physical implementation.

The computational model provides the basis for ensuring consistency between different engineering and technology specifications (including programming languages and communication mechanisms) since they must be consistent with the same computational object model. This consistency allows open inter-working and portability of components in the resulting implementation.

This specification does not aim at representing a fixed, complete, specification of all possible interfaces that may be necessary for any requirement of any healthcare enterprise. It specifies only a set of characteristics – in terms of overall organization and individual computational objects, identified as fundamental and common to all healthcare organizations, and that are satisfied by the computational model implemented by the service architecture.

Preserving consistency with the provisions of this part of ISO 12967, physical implementations shall allow extensions to the standard computational model in order to support additional and local requirements. Extensions shall include both the definition of additional properties in the objects of the standard model and the implementation of entirely new objects.

Also, this standard specification shall be extendable over time according to the evolution of the applicable standardization initiatives. The specification of extensions shall be carried out according to the methodology defined in Clause 7 of ISO 12967-1:2019, which identifies a set of healthcare common information services, describing their need and the methodology through which they will be used.

These information services are only the minimal set identifiable according to the needs of the healthcare enterprise, and constituting the service architecture (i.e. the integration platform) to serve as the basis for healthcare applications, e.g. EHR or patient administration.

This international standard (IS) establishes the Reference Standards Portfolio for the Clinical Imaging Domain (as defined in Section 4).

The Clinical Imaging RSP lists the principle health information technology (HIT) standards that should form the basis of implementing and deploying interoperable applications. These standards have been selected as being mature, fit for purpose and the most appropriate to clinical imaging.

The Clinical Imaging RSP includes a description of the domain, a normative list of standards, and an informative framework for mapping the standards to example deployment use cases.

This work reflects the experience and learning of the international community in developing interoperability standards in clinical imaging domain, including representatives of:

•DICOM (Digital Imaging and Communication in Medicine)

•IHE Radiology (Integrating the Healthcare Enterprise)

•ISO/TC215 Health Informatics.

The primary target audience for this document is policy makers (governmental or organizational), regulators, project planners and HIT managers. The Clinical Imaging RSP will also be of interest to other stakeholders such as equipment and HIT vendors, clinical and health information management (HIM) professionals and standards developers.

The intended usage of this document is to inform decisions about selecting the standards that will form the basis of integration projects in geographic regions or healthcare organizations. For example:

•What standards to use for capturing/encoding/exchanging certain types of information

•What standards to use for interfaces between the devices and information systems that supportinformation capture, management, exchange, processing and use

•What standards to use for specific use cases/deployment scenarios

The selected standards, and/or corresponding RSP sections, may be useful when drafting project specifications.

It should be noted, however, that achieving full interoperability within a given environment or set of systems is a large endeavor of which the selection of underlying standards is an important component, but just one component. Additional guidance may be found in the Process section of the TR on IHE Global Standards Adoption [2].

This RSP was developed based on concepts and methodology described in the Healthcare Informatics – Reference Standards Portfolio (RSP): Development Framework. RSPs are an evolution of past work, such as that done by the Board of Directors of the American Medical Informatics Association [2].
