# BJH-perioperative-notes-bioGPT

This clinical foundational model is designed to predict potential risk factors / post-operative surgical outcomes from clinical notes taken during perioperative care. It was finetuned from the `microsoft/biogpt` model through a multi-task learning approach, spanning the following 6 outcomes:
- Death in 30 days
- Deep vein thrombosis (DVT)
- pulmonary embolism (PE)
- Pneumonia
- Acute Knee Injury
- delirium

## Dataset 
We used 84,875 perioperative clinical notes spanning 3 years worth of anonymized patient data from the Barnes Jewish Healthcare (BJH) system in St Louis, MO. BJH is the largest hospital in the state of Missouri and the largest employer in the greater St. Louis region! The following are the characteristics for the data:
- vocabulary size: 3203
- averaging words per clinical note: 8.9 words
- all single sentenced clinical notes

## How to use model

```python
from transformers import BioGptTokenizer, AutoModelForCausalLM
model=AutoModelForCausalLM.from_pretrained("cja5553/BJH-perioperative-notes-bioGPT")
tokenizer = BioGptTokenizer.from_pretrained("microsoft/biogpt")
```
*Note: Because of our distinct model architecture, you are required to train a distinct predictor or use a respective fully-connected network above the hidden state when deploying the model via `transformers`*


## Codes
Codes used to train the model are publicly available at: https://github.com/cja5553/LLMs_in_perioperative_care 

## Note:
The model remains private as it was trained on clinical notes from patients. Requests made with non-institutional emails (e.g., `gmail.com`) will be rejected. 
Reasonable requests from recognized institutional emails may have to undergo appropriate approvals to access the model.
