Step 2: Map clinical concepts to archetypes
Map them to existing archetypes or determine which new ones we need. Determine the state of the existing archetypes – do we need to modify or enhance with additional requirements? Consider all possible use cases for each archetype – the end result will be better if we can be as inclusive as possible for all clinical scenarios.
The archetypes identified for this Pregnancy record are:
Corresponding archetype concept name NOTE: is linked to the actual archetype in a CKM instance
|Antenatal Plan||An overarching plan for the patient's antenatal care||Antenatal Plan <INSTRUCTION.antenatal_plan>|
|Information Provided||Details of each piece of health education information discussed or provided to patient||Information Provided <ACTION.health_education>|
|Social Summary||Social Summary <EVALUATION.social_summary>|
|Adverse Reaction List||Adverse Reaction list is made up of multiple Adverse Reaction entries||Adverse Reaction <EVALUATION.adverse_reaction>|
|Family History List||Family History list is made up of multiple Family History entries||Family History <EVALUATION.family_history>|
|Diagnosis||Problem lists, whether current or past are made up of multiple Problem/Diagnosis entries – the same data pattern will be used in all instances||Problem/Diagnosis <EVALUATION.problem_diagnosis>|
|Recent Problem/Diagnosis List|
|Procedure list||Procedure list is made up of multiple Procedure entries||Procedure <ACTION.procedure>|
|Smoking consumption||Tobacco use <OBSERVATION.substance_use-tobacco>|
|Alcohol consumption||Alcohol consumption <OBSERVATION.substance_use-alcohol>|
|Obstetric Summary||Obstetric summary <EVALUATION.obstetric_summary>|
|Pregnancy Summary||An evolving summary of key data about a single pregnancy – either current or past||Pregnancy summary <EVALUATION.pregnancy_summary>|
|Examination Findings||Examination Findings <OBSERVATION.exam> Examination of the uterus <CLUSTER.exam-uterus> Examination of the fetus <CLUSTER.exam-fetus>|
|Current Medication List||Medication list is made up of multiple Medication instruction entries||Medication instruction <INSTRUCTION.medication>|
|Medication administered||Medication action <ACTION.medication>|
|Weight||Body weight <OBSERVATION.body_weight>|
|Body Mass Index||Body Mass Index <OBSERVATION.body_mass_index>|
|Blood Pressure||Blood Pressure <OBSERVATION.blood_pressure>|
|Fetal Movements||Fetal Movements <OBSERVATION.fetal_movements>|
|Fetal heart sounds||Heart rate and rhythm <OBSERVATION.heart_rate>|
|Urinalysis||The pattern for urinalysis is identical to the pathology test results, and in some cases will be performed in the lab, so the same pattern will be used||Pathology test result <OBSERVATION.pathology_test>|
|Pathology Test results|
|Ultrasound results||Imaging examination result <OBSERVATION.imaging_exam>|
KEY: Pink archetype names indicate those that are early drafts. Green archetype names indicate those that are reasonably mature – through previous reviews within CKM Red archetype names indicate those yet to be developed.
Step 3: CKM Review
Within CKM each archetype will undergo review rounds by a range of clinicians, terminologists, software engineers, informaticians and other interested experts. The purpose of each review round will be to fine-tune each archetype so that it meets the requirements for each stakeholder group.
Step 4: Create an openEHR template
Once community consensus is reached within CKM, the archetypes will be aggregated and constrained in a template to accurately meet the specific use-case requirements for this particular Pregnancy Health Record. Each bold, black heading in the the following screenshot represents an archetype. The Pregnancy Summary archetype has been opened up to see the details. Black text indicates data elements that will be utilised in this use case; grey text indicates inactive data elements.
Other groups may use the same archetypes aggregated in a different order and constrained in a different way to represent their version of the Pregnancy Health Record. As the data in both Pregnancy Records is being recorded according to the same pattern, dictated by the underlying archetype, the information can be exchanged without ambiguity or loss of meaning.
