xml and messaging

1. XML and Messaging Chris Carrigan National Coordinator Cancer Registration, England

3. Its all about Interoperability Messaging XML Interoperability �The ability of two or more systems or components to exchange information and to use the information that has been exchanged� � IEEE, 1990

4. So why the cancer registries?

5. Action Programme (DH 2001)

6. Action Programme (DH 2001) So we need to exchange And we need to useSo we need to exchange And we need to use

7. Cancer Registry Needs� Data currently collected by different mechanisms Standard electronic data NHS Trusts to prove and adopt To use XML To roll out use of the Cancer Data Set This slide to outline briefly the current position with the Cancer Registry data collection and where they are looking to go. Mainly manual data collection by various means. Introduce the vision for consistent electronic data collection to ensure good data quality and improve data collection coverage and timeliness The government requirement is to use xml as the standard inter system data exchange (message) format Any cancer registry message developed will be built using the National Cancer Data Set items.This slide to outline briefly the current position with the Cancer Registry data collection and where they are looking to go.

8. So how is this happening? Modernisation Funding Network Liaison Roles Cancer Dataset Message-based Systems Rules-based Interpretative Systems

9. Cancer Dataset Cancer dataset is a �Fundamental Standard� Operational instances of audit dataset messages based on fundamental standard Cancer waiting times LUCADA � Lung Head and Neck Is this sustainable? This slide to give some back ground to the development of the cancer data set to strategic standard and the various operational develops that have been started/approved based on this. Cancer data set approved by Information Standards Boards as a strategic standard in January 2003. Work continues to develop and pilot remaining cancer areas (Haematology, Childrens, Palliative and Primary Care) Cancer dataset consistent with common items in National Cancer Registry data model. Waiting Times Data Collection � from Dec 2002 Potential to act as trigger for Cancer Registration NCASP � National Clinical Audit Support Programme Breast, Lung, Head & Neck and colorectal 2003 XML message has been developed for LUCADA This slide to give some back ground to the development of the cancer data set to strategic standard and the various operational develops that have been started/approved based on this.

10. NHSIA Messaging Project Collaborative Project with the NHSIA Registries Define the Key Event Requirements Define the Metadata NHSIA Build the XML Schema for Cancer Build messages using the Cancer Dataset Formal routes through ISB Testing, Pilot, Standard, Adoption

13. So what messages are there?

14. What does the XML schema look like?

15. Current registration process

16. Change in data sources over time

17. Implementation Stages Stage 1 test the transmission of Cancer Registration data items from NHS Trusts to Cancer Registries using NHS XML schema data items collected in current mixed formats and converted into messages capable of transmission to Cancer Registries

18. Stage 1 process for registration

19. Implementation Stages Stage 2 will utilise the new services to be available from the Secondary Uses Service (SUS) of the NHS Care Records Service (NCRS). This service will use the Transaction Message Service (TMS) feeding the National Spine via XML schema produced from an HL7 Version 3 Reference Information Model (RIM). The Cancer Registries will then take the data feeds as a user of the NCRS/SUS

20. Final process for registration

21. Pilots Kent Network solution Builds upon existing IT strategy Working with suppliers East Anglia Mapping of known data sources Testing the XML schema

22. Message development Cancer Registry Items in CDS V4.3 Cancer XML Schemas developed Pilots underway ISAB Submission Design Authority HL7 UK

23. How does this fit with the world? Why bother � NPfIT is coming�� How well does our model fit HL7? I bet someone stops you�. Why didn�t you use UML? Cancer as an exemplar?

24. Looking forward - NPfIT Electronic Booking functional December 2005 ETP 50% national implementation December 2005 100% December 2007 NCRS phase 1 December 2004 phase 2 December 2006 PACS 1/3 roll out by December 2004 completed December 2006 Infrastructure full connectivity March 2005 So how do you get into any of these agendas?So how do you get into any of these agendas?
