CORe Model - BioBERT + Clinical Outcome Pre-Training

Model description

The CORe (Clinical Outcome Representations) model is introduced in the paper Clinical Outcome Predictions from Admission Notes using Self-Supervised Knowledge Integration. It is based on BioBERT and further pre-trained on clinical notes, disease descriptions and medical articles with a specialised Clinical Outcome Pre-Training objective.

How to use CORe

You can load the model via the transformers library:

from transformers import AutoTokenizer, AutoModel
tokenizer = AutoTokenizer.from_pretrained("bvanaken/CORe-clinical-outcome-biobert-v1")
model = AutoModel.from_pretrained("bvanaken/CORe-clinical-outcome-biobert-v1")

From there, you can fine-tune it on clinical tasks that benefit from patient outcome knowledge.

Pre-Training Data

The model is based on BioBERT pre-trained on PubMed data. The Clinical Outcome Pre-Training included discharge summaries from the MIMIC III training set (specified here), medical transcriptions from MTSamples and clinical notes from the i2b2 challenges 2006-2012. It further includes ~10k case reports from PubMed Central (PMC), disease articles from Wikipedia and article sections from the MedQuAd dataset extracted from NIH websites.
