Hi Joost,
I don’t have a simple answer for this. The nurses I speak with want to be able to record nursing diagnoses, but they are equally clear that this should not be confused with a formal medical diagnosis.
I am no expert, and any nurse is welcome to correct me, but my understanding is that a nursing diagnosis is not a single clinical concept in the way a medical diagnosis is.
I suspect our plan to develop the functional suite of archetypes that we developed in the SparkedAU project will support important aspects of nursing diagnoses:
- EVALUATION.functional_impairment_summary (TBD) can capture the problem label, corresponding to the P in a PES statement. It may be appropriate to nest CLUSTER.symptom_sign within this archetype and to include a data element for aetiology, corresponding to the E in PES, which can reference relevant contributing conditions or diagnoses in a similar way to how clinical indication is recorded in other archetypes.
- OBSERVATION.functional_ability captures the observable evidence, corresponding to the S in PES, as reflected in the revised concept that replaces the former ADL summary. This archetype is replacing the ‘ADL summary’ which is currently iterating through the review process.
- EVALUATION.functional_independence_summary (TBD) captures the level of dependence and associated care requirement.
Once these three archetypes are reviewed and published, we will be better placed to identify any remaining gaps and address them as needed.
Curious to see if our nurse colleagues agree… 
Regards
Heather
