Student Study: Washington Medical Center – Study tracking Doctor and Nurses Time
Universal Data Issues
• Lots and lots of data scattered around• Very diverse data types• Legacy systems everywhere• No standards• Too many standards• Traditional business practices work against
integration & sharing
Universal Data Problems
• Completeness problem– Hard to know whether you have all the known
data• Correctness problem
– Hard to resolve conflicting or incorrect data• Access problem
– Hard to get at data even when you know some information exists in a particular place
• Organization problem– Hard to put it all together
• Time problems– Time resources, delays, response speed
“XML as a common way of describing data is important to deliver true interoperability”
Why Does Microsoft Care About XML
• Work started in 1997
• Microsoft bet the company on this with .NET in 2000
• Had a major impact on all software systems: OS, database, Office, services
• Industry-wide adoption
• Competition on implementation
Simple adaptors allow connection to any power outlet in Europe
Industry standards for interoperability• Software that talks to other software
over the network • Based on Internet standards• Works with any operating system• Loosely coupled programming• Preserve and connect existing systems• Integrate inside and outside the firewall• Broad industry support
So why is this important?

Best Practices XML/HL7 in Action
• New Zealand Health Connection Engine (HCE)– Brings together primary care, pharmacy, lab and tertiary
care integration regardless of existing systems by using XML, Web Services and HL7
• Singapore EMRX (Electronic Medical Record Exchange)– Integrates tertiary care patient record with lab results and
more to create a single patient record that can be shared amongst hospitals
• Korea Yonsei University Medical Centre– integrating and interconnecting, OCS, EMR, PACS (Picture
Archiving and CommunicationsSystems) and ERP (Enterprise Resources Planning) systems
– Taking this further through the creation of an HER and extending building the base for CDSS (Clinical Decision Support Systems)
