openEHR Archetypes IComputable models of discrete clinical concepts

Familiar components of a health record

Blood pressure, Body weight, Symptom

Medication order, Family history

Prostate cancer histopathology result

‘Maximal dataset’ philosophy Capture as many clinical perspectives as possible

Universal use case

openEHR Archetypes IIcan be designed for specific local use case

particular data entry screen

local message

most useful when designed to be shared and reused

“What do WE mean by pulse rate”

Potential for a SINGLE, SHARED

MODEL of clinical content

Archetypes are based on RM ‘classes’

EHR

Folders

Compositions

Sections

Entries

Clusters

Elements

Electronic health record for one person

High level organisation of the EHR,e.g. by episode or by specialty

Set of entries comprising a clinical care session or document, e.g. encounter, result

Clinical headings reflecting workflow or consultation process

Clinical statements about observations, evaluations, instructions, actions

Entry subcomponents, e.g. device details or inspired oxygen information

Leaf nodes of name-value pair and datatype, e.g. body weight = 60kg (Quantity)

Archetype namingConcept name: the human name of the clinical concept

‘Blood pressure’, ’Report’

ArchetypeID: the technical name used by tooling and CDRs

‘openEHR-EHR-OBSERVATION.blood_pressure.v1’

‘openEHR-EHR-COMPOSITION.report.v1’

Naming examples

SLOTS

Allow modeller to leave a gap

‘plug in’ another archetype

Allows complex ideas to be built up by mixing different combinations of archetypes

SLOT ConstraintsDetermine which archetypes can fill the slot

Good practice

Keep slot options ‘open’

Use the slot constraint to define common slot fills

Only occasionally ‘lock down’ the slot to specific archetypes

Slot constraint examples

COMPOSITION archetypes‘Top level document’ container for all clinical data

All clinical data saved inside a Composition

Represent generic document types in clinical system

Encounter, Report, Lab Report

Problem List, Discharge Summary, End of Life Care plan

Simple

Do not define detailed content.

SECTION archetypesSub-divide complex compositions

No ‘semantic’ meaning

Meaning carried in ENTRY archetypes names inside SECTIONS

Very few pre-defined SECTION archetypes

ELEMENT archetypes

Single datapoint only

Allows re-use in other archetypes

No current use case

SpecialisationAllows new child archetype to be defined

‘Inherits’ all of the content of the parent e.g. Lab_test_panel => Blood Lipid test panel

Add new elements, clusters

Rename nodes

Add coded lists

Common aspects of both parent and child archetypes remain compatible

LocalisationSpecialisation can be helpful for adding / adapting an international archetype for local use

Adding new nodes

Renaming existing nodes

Does impose overheads

filling slots with local cluster archetypes often easier to maintain

Localisation by slot-filling examples
