Title: Applications of XML in the NHS


1
Applications of XML in the NHS
  • Paul Woolman
  • Standards Program Manager
  • ISD

2
Contents
  • XML for
  • Patient Records
  • Publishing
  • Communications

3
Patient records
  • Store clinical information as XML
  • Structured documents
  • Case notes
  • Discharges
  • Referrals
  • Summary documents
  • Structured data
  • XML data model

4
Information storage
  • XML as the format for authoring and storage of
    documents
  • Rather than Word .Doc, Rich Text Format, Text
  • Clinical documents
  • Metadata (description of documents)
  • Latest Office applications (MS, SUN, Open)

5
Examples
  • Graphnet
  • CSW
  • Office
  • Anaesthetic records
  • Next 4 slides

6
Office applications
  • MS office, Sun, OpenOffice
  • store use XML documents
  • Infopath forms client
  • Supports web services XML
  • Build forms from xml schema

  • XML for
  • Patient Records
  • Publishing
  • Communications

12
Publishing
13
Document Metadata
  • Data about datadescriptions eg keywords
  • Descriptive headings about documents
  • Useful for filing, searching and cataloguing
  • E-Government metadata standard
  • HL7 Clinical Document Architecture
  • need NHS Scotland standards

14
SHOW NELH
  • Main NHS portals
  • HTML pages need manual updating
  • XML data storage
  • XML -gt HTML in active server pages
  • Advantages
  • Many views of single data
  • Support clinical networks
  • Support automated query tools

16
NHS Data Dictionary
  • Data definitions on web
  • XML export selected definitions
  • UML models designing XML schema refer to data
    definitions.
  • New dictionary to tie all three together

17
Contents
  • XML for
  • Patient Records
  • Publishing
  • Communications

18
Communications
19
Electronic Data Interchange
  • Moving data from one computer to another
  • Eg Patient referral from GP to hospital
  • Replace older formats eg EDIFACT
  • New forms of EDI with user interaction
  • XML allows Graceful Degradation
  • View messages if required

20
GP records exchange
  • Patient moves house or changes GP
  • Records follow 4 weeks later
  • Electronic exchange is quicker
  • GPASS early implementations ongoing

21
NHSScotland GPEX
  • GPASS specific message
  • GP exports XML document to PSD
  • PSD send off to new GP update CHI
  • New GP selectively imports record into new GPASS
  • Currently in early implementation sites

22
Scottish Birth Record
  • Replaced SMR for births
  • Added clinical information
  • Make useful to clinical care
  • Rolled out to all maternity units

23
Concept
  • Single web site in NHSnet
  • Browser input from maternity units
  • Link to PASs
  • Link to new maternity systems
  • Reduce data duplication
  • Link to CHI
  • Give baby new CHI number at birth

25
Use of XML
  • CHI link
  • Maternity system
  • Ongoing development

26
Community Health Index (CHI)
  • Mainframe application
  • Green screen terminal input
  • Need machine EDI input query

27
Concept
  • Casablanca XML to VMS transform application
  • NHS Standard XML Schema
  • Web server
  • HTTPS and XML input to active server pages

28
XML messages
  • Register new patient
  • Find patient
  • Responses

29
SCI integration
  • SCI Store every health board
  • Labs systems feed into Store
  • E-Biz 2000 middleware XML

30
Test requests and results reporting To achieve
this SCI first has to integrate existing hospital
systems and re-assemble the patients information
in a new system called SCI Store
OK
3.2

31
SCI web services
  • Electronic Transmission of Prescriptions
  • Referrals to outpatients
  • SCI Gateway
  • David Brazier this afternoon

32
E-Care
  • Shared care records between health, social
    services, education and others
  • Eg Shared Assessments
  • Elderly
  • Mental health
  • children

33
Single Shared Assessments
  • Lots of work on data and definitions
  • Based on paper versions
  • Initiated by any party
  • Involves patient/client and relatives/carers
  • Involves independent sector
  • Eg churches, voluntary orgs.

34
Concept
  • Server in demilitarized zone
  • XML integration to health system
  • XML integration to social work system
  • Browser input

35

36
E-care store
  • Central data store
  • Multiple identifiers CHI, Hospital nos., social
    work numbers
  • XML Web Services for data exchange

37
Virtual EHR portal
  • Pull data from distributed systems
  • Rearrange
  • Present to viewer
