EHR development
• Project started 2001 first phase complete end 2002• Joint work ongoing with NHS England• ENV 13606 prime candidate• Various problems identified• NHS profile required ??• Evaluating options for
– GP summary input– Hospital event input (referral, discharge)– Patient access– Overall architecture
Shared care with local authorities

Analysis
Provisional!
Based onENV 13606Architecture ??
XML Dictionaryfor NHS Scotland and
ENV13606Repository of standard XML tags reusable
fragments and Schema for clinical content
Motivation: nothing exists !
Started early 1999
Scope of Dictionary
• To support creation of Schema used in NHS
• Enable interoperability of clinical data between vendors
• clear definitions of elements matched to standard dictionary of terms.
Priorities• Discharge letter• Referral letter• Clinic letter• Lab results• Test ordering• GP-GP record exchange• Find CHI information• Request new CHI number• Provide Birth record• GP-EHR summary• Trust – EHR event
Standards development
• Make Public Open Schema• Include manufacturers (consensus)• Include professional bodies• Accreditation
- testing - conformance
Standards input & compromise• Sources
– SIGN publications, ISD published standards, XML implementations, existing EDIFACT messages, paper samples, Headings, READ, ENV13606
• Consultation
– Professional clinical bodies, manufacturers, pilot & test
• Implementation IT training & timing
– Short time scales
– Limited expertise & funding
– Realistic expectations
• Architecture considered for EHR and Store mk 2
• NHS Data Dictionary and XML Standards repository terminology
• Teeside confidentiality model incorporated into CareNet and SCI Store mk 2 (provisional)
• Schema closer relationship with ENV part 4
• Evaluate REALISTIC working solutions to NHS developments within given constraints
Current ENV 13606 work
Issues with ENV
• Migration path from current Store• Full working models in short supply (none ?)• R&D development vs scaleable maintainable
24x7x365 working model• Functionality & timescales for development• Skills shortage (industry vs academic)• OO database – R&D (only?)• Relational Database – Industrial strength,
scaleable, high performance - required
Requirements
• Relational design from slim NHS profile• Address confidentiality issues for deployment• Create real working models• Don’t change the standard (too much)
• Use now, 3yrs from now, or 20yrs from now ?
