I have built machine learning models that rely on unstructured data such as clinical notes, and structured data such as observations, labs, diagnoses, treatments, conditions, in order to give clinicians a risk score – for patient readmission, maternal health, mental health, and other areas of medicine. An example is here: [1904.05342] ClinicalBERT: Modeling Clinical Notes and Predicting Hospital Readmission that has been used at academic medical centers in the US.
Do you know if anyone or any organization has deployed clinical decision support tools on top of openEHR that use machine learning, such as a decision tree model?
Would love to see the implementation to understand what would be involved, and build a technical roadmap to implement such a thing. Feel free to forward if someone in your network may know who I should chat with.
Thanks!

Probably overkill, but I happen to have a PhD on the topic (more or less, since I aimed for the moon with Bayesian Networks…)
I’m not aware of decision trees running on top of openEHR. Implementation-wise @rong.chen is the person who’s probably ahead of everybody in terms of using openEHR for CDS.
Not my field at all but on a quick read of your paper @jaan, it looks as if, by providing highly structured. contextualised data, openEHR should remove the need for the kind of clinical note processing that you are doing.
Seems like an interesting new project to do a comparison of highly structured data ‘at source’ vs. what you can do with narrative processing, as input to the decision support?
you’re welcome @NeoEHR , thanks for the kind words.
I assure you it’s better to be on the reading side of 257 pages than the writing side…
I think they’re great, but they became this niche technique, especially with neural networks blowing up once the problem of training them at scale in parallel was solved. I suspect there’s some convergence now, but BNs in general have fallen out of favour. I personally think it’s a shame but it is what it is.
