Data Standards and Products - Implementation CfH Interoperability Toolkit (ITK) Overview and Positioning Principles Selected Standards Profiling IHE-UK and HL7-UK involvement ‘Unifying the Belts’ Pilots Questions

Data Standards and Products - Implementation Overview and Positioning Christine Connelly made a public commitment to the development of a toolkit for interoperability. The objectives of this work are as follows: The publication of a set of standards and frameworks for interoperability covering transactional and analytical services – by end Sept 09 The implementation of the services for use by third party – by end March 2010 The development of guidance for the use of the standards – by end March 2010

Data Standards and Products - Implementation Overview and Positioning Publication of specifications will be driven by pilot (proof of concept) use cases. September publication is ‘draft - for consultation’ inviting comment and opportunity for refinement Specification development will continue beyond September in association with: Vendors associated with pilots HL7-UK IHE-UK Note: On completion, Technology Office will seek ISB approval for the standards referenced in the specification

Data Standards and Products - Implementation Overview and Positioning Operating Model (Processes and Governance) National Profiles (standards) Applications (use of data) Standards are defined appropriate to the business scenario (e.g. HL7v2, HL7v2 XML, HL7v3) with focus on simplified XML to reduce barriers for new suppliers. Messaging Infrastructure exposes interfaces (based upon the standards) and provides technical services e.g. adapters, audit, routing, security Applications use adaptors (or standards directly) to execute business processes Operating Model provides enabling processes and governance Standards are defined appropriate to the business scenario (e.g. HL7v2, HL7v2 XML, HL7v3) with focus on simplified XML to reduce barriers for new suppliers. Messaging Infrastructure exposes interfaces (based upon the standards) and provides technical services e.g. adapters, audit, routing, security Applications use adaptors (or standards directly) to execute business processes Operating Model provides enabling processes and governance Application Suppliers Messaging Infrastructure (connectivity) Middleware Suppliers

Data Standards and Products - Implementation Principles Established standards (Best-of-Breed) Proven and established standards will be used wherever relevant. A flexible, best-of- breed approach will be used to select the standards most appropriate to the integration task in hand. Practical approach The Toolkit is not an academic exercise. All Toolkit development will be based on genuine business problems and pilot implementations in a Live Trust environment. Lean but extensible The Toolkit will contain only the features necessary for concrete practical scenarios, with no unneeded theoretical “baggage”. On the other hand, there is a balance to be struck – and the lean approach means that it is important to plan in extensibility for future needs. Low barriers to entry Clear standards will explain clearly what is required to participate in the market. Standards definitions will be kept simple and based on widely understood technologies (e.g. Web Services, XML)

Data Standards and Products - Implementation Principles Toolkit (ITK) The initial tranche of message payloads identified for the pilot deal with the Administrative domain. Therefore HL7v2.4 XML has been selected as the most appropriate standard. PID||| ||EXAMPLE^DAVI D^S|| |M|||23MAINSTREET ^^ANYTOWN^ HL7 v3 (Lite) National HL7v2.XML Web Services HL7 v3 (Lite) National HL7v2.XML HL7 v2 (Lorenzo) HL7 v2 (Cerner) HL7 v2 (Kiosk) New Toolkit App (external) New applications can build directly to the Toolkit standards. No adaptor needed Standard adaptors, provided with the Toolkit for common conversions Bespoke adaptor, developed by existing Kiosk vendor

Data Standards and Products - Implementation Standards Choice Initial Choice: HL7 version 2.4 initially based on HL7-UK Version 2.4 A2 Proposal to ‘profile’ this for use in the UK with HL7-UK and IHE-UK support Eventual submission to NHS Information Standards Board  National / International Standards  Exiting system capability  Timescales  Proof of Concept scenarios  Extensibility and future requirements (native pipe and hat over MLLP) Decision to natively support the XML format of HL7v2.4 over web services Provide native toolkit adapter to convert ‘|^’ (pipe and hat) over MLLP

Data Standards and Products - Implementation Examples Traditional ‘^|’ form of HL7: MSH|^~\&|PAS|ORG1|LSP|ORG1 | ||ADT^A01^ADT_A01 … XML form of HL7: | ^~\& PAS ORG1 LSP ORG ADT A01 ADT_A01 …..

Data Standards and Products - Implementation ITK Reference Tables We have started a process of reviewing all the reference data tables in the HL7v2.4 specification in order to identify mismatches with PDS, SDS, NHS Data Dictionary etc. Part of the profiling process will be to agree a common set of nationally agreed reference values (where appropriate) Invitation to all stakeholders to engage in this review process

Data Standards and Products - Implementation HL7v2.4 XML Benefits of choosing HL7v2.4, XML over Web Services: Continue support for National Standards Minimal change to current application capability Provision of ‘toolkit adapters’ for standardised transforms (Pipe and Hat -> XML) Ability to cross enterprise boundary using existing TMS/N3 protocols ‘Black Box’ toolkit services, abstracted from vendor services. Ability to easily extend range of services provided through toolkit

Data Standards and Products - Implementation The Pilots - background A key aspect of the current Toolkit work is that it is based on practical pilots The aim is not just to create documents and specifications, but also to demonstrate the Toolkit in use within real-world NHS Trusts By working closely with stakeholders to develop the Toolkit approach, the aim is to deliver business benefit from the very start Note that the initial pilots are based on iPM and Cerner.

Data Standards and Products - Implementation The Pilots Clinical Domains? Administrative Domains Other? Scope of pilot Potential future directions

Data Standards and Products - Implementation Directions – Interoperability Coverage Local Health Community Acute Trust Cross Health Community / National Services? Initial pilot scenarios, based around interoperability within an Acute Trust Potential future directions – linking Toolkits to the Spine and/or each other? Further pilot scenarios to enable Local Health Community interoperability (e.g. GP)

Data Standards and Products - Implementation Pilot Scenarios Scenarios identified include: ScenarioBenefits SMS RemindersReduction in DNA Self-Service Outpatient Kiosks Reduction in Resource/Improve Data Quality Patient Ward/specialty transfer Reduction in Resource/Improve Data Quality NHS encounter summary Cross-care exposure
