  1. Technical Perspectives Mat Jordan Steve Anderson

  2. Current situation - 1 • SCR will not be available for CAF messages within the lifetime of the programme • No national NHS systems will be CAF enabled within the lifetime of the CAF programme* • Without end-to-end systems, National Integration Centre (NIC) will not give priority to CAF messaging projects • Full CAP is still required for point-to-point messaging through the Spine using TMS (a lighter CAP may be available but not for 6+ months) • * There is still a possibility that TPP System 1 might be CAF enabled before March 2012.

  3. Current situation – 2 • GCSX / N3 Gateway is available – no need for IGSoC and separate N3 connection • Specifications for all CAF messages are now available (assessment & care planning, delayed discharge and continuing healthcare assessment) • All CAF messages are now ‘universal’ so can be sent by non-Spine transport mechanisms • Spine can still be used for point-to-point messaging between systems using the Transaction Messaging Service (TMS) • DH Technology Office have agreed to provide additional support for local messaging

  4. Options • Build point-to-point CAF messaging functionality based on Spine / TMS • Look at local messaging options • Interoperability toolkit (ITK) • Data Transfer Service (DTS) • NHS Mail • Locally agreed interface

  5. Point-to-point via Spine • Both health and social care systems are required that can be CAF enabled in time: • Already PDS enabled or well on the way • Ready to start CAP for CAF messaging soon • Functionality could possibly be built at risk for future use

  6. Interoperability Toolkit • Standardised web service-based interface between two systems • Requires local assurance • Purported to enable rapid development • Technology Office have agreed to support this • But: • Still requires both NHS and social care systems that can be upgraded in time • Does not yet include social care messages • Assurance process for social care not yet defined

  7. Email / DTS • Crude but effective mechanisms for sharing information between organisations • Cheap and widely available • But: • Unsophisticated • Requires careful management • Partial solution – may be first step towards better sharing

  8. Other local interfaces • Locally agreed point-to-point interfaces between systems using Universal CAF messages • Agreed standards for interoperability • Agreed between supplier and customers • Agreed across all interested CAF sites? • Ownership and maintenance of standards would need to be agreed • Local assurance processes would need to be developed and agreed • How can replicability be supported?

  9. Key questions for sites • What can be achieved locally within the demonstrator timescales • What tactical solutions are possible? • What would make sense as part of a longer term strategy? • What, if any, messaging requirements do you envisage (dates of build and test)? • What standards will be required? • What existing standards are appropriate (e.g. NHS Number)? • Is a Demonstrator-wide standards group required? • What support will be required from DH / CFH / Others?

  10. Next steps • Technical roadmap: • Clear technical scope for each site • Short term and long term options • Informed by meetings / workshops • Support requirements from DH / CFH / Others • Standards – cross site agreement on standards
