The ITK accreditation releases contain tools and guidance for attaining accreditation to the ITK Standard, applicable to all system suppliers seeking accreditation.

To attain ITK accreditation a vendor must demonstrate the technical conformance of their product to the ITK requirements specifications by submitting evidence to HSCIC for review. This is achieved using the ITK Toolkit Workbench, completing the Supplier Certified Requirements Coverage checklist, and by providing supporting evidence.

Successful accreditations are listed within the ITK Accreditation Catalogue.

ITK Architecture

These documents are intended for a mixed technical audience, specifically those intending to develop ITK Accredited Systems, as well as those in the Health and Social Care Architecture communities.

There are 8 documents in 2 categories. The first part provides an overview of both the ITK and ITK Accreditation.

ITK Security Requirements Accreditation and Concessions

As part of an extensive review of the ITK Architecture Specifications during the latter half of 2012, a team of representatives from the Centre and the suppliers agreed a number of changes to the way ITK messages are authenticated.

The changes reflected implementation difficulties presented by the nature of the WS-Security header signing specification given current development platforms, and addressed the inclusion in ITK, of multi-hop and non-SOAP transports. Technical details on the reasons for these changes are given in ITK Security Briefing Paper – Strawman Proposals.

The concessions discussed here will form part of the intended refresh and update to the ITK Architecture Specifications planned for completion by autumn 2013.

Releases of this item must be used in conjunction with the ITK Web Services Transport Specification found within the related documents section of the ITK Core releases.

ITK Trust Operating Model

The Trust Operating Model is an integral part of the Interoperability Toolkit. It details the Trusts’ responsibilities for Locally Assured Systems and Spine Mini Service compliant systems.

The main audience for the Trust Operating Model are project teams working for a deploying organisation who are responsible for the runtime requirements of the implementation. Suppliers are envisaged as a secondary audience for the Trust Operating Model documentation.

The documentation has 2 categories, Guidance and Governance, and these are more relevant to the Project Manager and technical team within a deploying organisation. Senior management may find the overview document relevant and may want to read the information on Governance and Stakeholders.

Legally restricted patient confidential reference data

The technical preview code list was originally drafted to support a refresh of the ISB 1572 Sensitive Data standards and for no other purpose.

The legal basis for patient identifiable data and sensitive information changed with the introduction of the Health and Social Care Act 2012. However, the legal and policy context and interpretation for sensitive and/or legally restricted data has not been fully established due to the changes in legislation since the original standard was released.

As a result, this supporting code list has remained static since April 2016. NHS Digital will update the codes once an updated policy and instruction is provided by our commissioners.

Some subsets will be listed in more than one category - this is intentional, and the subset content will be the same. We suggest you register for domains of interest, rather than selecting all, or be aware that some duplication will occur.

We recommend subscribing to this item to receive updates of the latest content before formal release.

We welcome feedback on any of the products, but especially early in the lifecycle of the product it is useful to have feedback on how products are intended to be used or any definition or quality concerns users (or potential users) have. Where subsets relate directly to your domain of practice, there may be opportunities to be more actively involved in development or ownership of the subset. This particularly applies to domain experts within professional bodies - contact the subset service via information.standards@nhs.net.

SNOMED CT UK Query Table and History Substitution Table

Releases of this item contain 2 related derivatives of the SNOMED CT UK Edition to aid the processing of inactive content within systems and data repositories.

The History Substitution Table provides a single table identifying valid substitutions for concepts that are now inactive, along with metadata about that substitution; it is computed using the historical relationships within the main SNOMED CT release but presented as a simpler look-up table.

The Query Table is an extension to a normal SNOMED CT transitive closure table, taking into account the History Substitutions Table and other data. It provides a mechanism to achieve optimal data retrieval, regardless of inactive and active concept status in data or query definitions. The Query Table is recommended as a mechanism for ensuring inactive content is still returned in searches, and is specifically recommended by the Joint GP IT Committee for use in primary care systems.
