1 Integration Projects at Portsmouth Hospitals Trust Andrew Sergeant ICT Development Manager Island and Portsmouth Health ICT Service (IPHIS)

2 IPHIS IPHIS is a shared services consortium that provides IT Services to: Portsmouth Hospitals NHS Trust Portsmouth City PCT East Hampshire PCT Fareham and Gosport PCT Part of Hampshire Shared Financial Services Part of Hampshire Partnership Trust 76 General Practices (Estimated 12,500 users)

3 HL7 & NPfIT Prepare for NPfIT IDX Carecast NPfIT - HL7 version 3 Portsmouth - Part of Southern Cluster (LSP: The Fujitsu Alliance) Currently internal systems utilise HL7 version 2.x

4 Current Infrastructure Many older servers (over 3 years) and not under support agreements Multiple data feeds between a large number of systems and servers Many versions of HL7 Version 2.x to contend with

5 New Infrastructure Web Server Cluster (16 HP Blade Servers - Windows Server 2003, IIS) Database Cluster – 2 x HP DL580 (Quad CPU, 6Gb RAM, 6*HDD) SAN - HP EVA 5000 Centralised around EPR project – XML based data warehouse

6 EPR Project XML Data warehouse ASP.NET interfaces for key departmental applications (e.g. A&E, MAU) XML Web services providing data exporting facilities to SHA

9 Integration Engines Using Cloverleaf – good for file IO, but difficult to access programmatically as native code is TCL Standalone.NET applications outputting XML and HL7 version 2.x between systems Evaluating new Integration Engines

10 XML Web Services Cancer Minimum Dataset from Portsmouth Hospitals Trust CMI system to SHA Clinical Data Repository XML Schema based on Cancer Dataset V4.0 SQL Server 2000 For XML Explicit Stored Procedure.NET XML Web Service (C#)

12 Demo 1 Web Service Demo

13 Internal Integration Strategy XML Web Services to pass data between in-house developed systems XML and HL7 version 2.x messaging between 3 rd party systems HL7 version 3 is one standard and so easier to create specific handler classes in.NET to convert XML messages (unlike 2.x)

14 Demo 2 XSLT Demo as used by HL7 Handler classes

15 Future Technologies Replace Integration Engine More Web Services More.NET Applications InfoPath?
