Patient records

Patient records

  • Store clinical information as XML

    • Structured documents

      • Case notes

      • Discharges

      • Referrals

      • Summary documents

    • Structured data

      • XML data model


Information storage

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)


Examples

Examples

  • Graphnet

  • CSW

  • Office

  • Anaesthetic records…

  • Next 4 slides…


Office applications

Office applications

  • MS office, Sun, OpenOffice

    store & use XML documents

  • Infopath forms client

    • Supports web services & XML

    • Build forms from xml schema

  • Advantages:

    • Many views of single data

    • Support clinical networks

    • Support automated query tools


Nhs data dictionary

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

Communications


Electronic data interchange

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


Gp records exchange

GP records exchange

  • Patient moves house or changes GP

  • Records follow 4+ weeks later

  • Electronic exchange is quicker

  • Added clinical information

  • Make useful to clinical care

  • Rolled out to all maternity units


Concept

Concept

  • Single web site in NHSnet

  • Browser input from maternity units

  • Link to PAS’s

  • Link to new maternity systems

    • Reduce data duplication

  • Link to CHI

    • Give baby new CHI number at birth
