CORe Model - Clinical Mortality Risk Prediction

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.

This model checkpoint is fine-tuned on the task of mortality risk prediction. The model expects patient admission notes as input and outputs the predicted risk of in-hospital mortality.

How to use CORe Mortality Risk Prediction

You can load the model via the transformers library:

from transformers import AutoTokenizer, AutoModelForSequenceClassification
tokenizer = AutoTokenizer.from_pretrained("bvanaken/CORe-clinical-mortality-prediction")
model = AutoModelForSequenceClassification.from_pretrained("bvanaken/CORe-clinical-mortality-prediction")

The following code shows an inference example:

input = "CHIEF COMPLAINT: Headaches\n\nPRESENT ILLNESS: 58yo man w/ hx of hypertension, AFib on coumadin presented to ED with the worst headache of his life."

tokenized_input = tokenizer(input, return_tensors="pt")
output = model(**tokenized_input)

import torch
predictions = torch.softmax(output.logits.detach(), dim=1)
mortality_risk_prediction = predictions[0][1].item()
