Data Standards
The use of data structures and OpenEHR
Richard Kavanagh, Head of Data Standards, HSCIC
What are Data Structures?
• Definitions of Information components used
within Interoperability
– Blood Pressure
– Blood Spot Screening Results
– Appointments
• Reusable definitions that are not based on
any one implementation technology
• They are “documentation” assets not
implementation assets
2
Why do we need them?
• Promotes reuse between different
implementation forms
• Provides a “semantic target” for information
structures
• Is more accessible than technical notation in
HL7v3, HL7v2 etc.
• Enables engagement with less technically
skilled people
3
The anatomy of a Data Structure.
Metadata to
describe the data
structure
The individual data
items & their
relationship to each
other
Their data types,
optionality, coding
details, definitions
etc.

• Discrete component parts
• Groupings of data items
• Parent<>Child relationships
• Text, Integer, Quantity, Coded etc
• SNOMED, dm+d, NHS Number
• Mandatory / Optional

The use of OpenEHR
• A common reference model for all structures
to drive consistency
• A stable set of open source tools for creating
models, freely available today
• A growing community creating openEHR
models (incl. Integration Pioneers)
• Options for publishing and collaboration
platforms
8
How will HSCIC use openEHR?
• We WILL use it for creating data structures (aka
archetypes) for interoperability standards going
forwards
• We WILL use the publicly available openEHR
tooling for creating our models
• We WILL publish our models in formats including
openEHR formats
• We WILL NOT use openEHR as the messaging
layer
• We WILL use openEHR for documentation, not
implementation
9
When will it arrive?
• Multiple projects are in progress within
HSCIC that are using “Data Structures”
• This is being embedded into the internal
development methodology
• Some retrospective modelling is expected
during Q1/Q2 next year

– Allergies & Adverse Reactions
– Blood Pressure
– Document Metadata

GPSoC IM2 (Prototypes)
• Working with industry partners:
– Appointments
– Repeat Prescriptions
openEHR
FHIR

Questions
• What are your priority data structures?
• How do these align with what we are already
working on – how do we create synergies?
