Model Card for BioBERT Fine-tuned on MIMIC-3 for ICD-9 Code Classification

Model Details

Model Description

This is a BioBERT model fine-tuned on the MIMIC-3 (Medical Information Mart for Intensive Care) corpus specifically for ICD-9 code classification. The model is designed to predict medical diagnostic codes based on Electronic Health Record (EHR) and symptom text inputs.

Uses

Direct Use

The primary use of this model is to automatically classify medical conditions by predicting relevant ICD-9 diagnostic codes from clinical text, such as electronic health records, medical notes, or symptom descriptions.

Downstream Use

This model can be integrated into:

• Clinical decision support systems
• Medical coding automation
• Electronic health record (EHR) analysis tools
• Healthcare informatics research

Out-of-Scope Use

• The model should not be used for direct medical diagnosis without professional medical oversight
• It is not intended to replace clinical judgment
• Performance may vary with text outside the medical domain or significantly different from the training corpus

Bias, Risks, and Limitations

• The model's performance is limited to the medical conditions and coding patterns in the MIMIC-3 dataset
• Potential biases from the original training data may be present
• Accuracy can be affected by variations in medical terminology, writing styles, and complex medical cases

Recommendations

• Validate model predictions with medical professionals
• Use as a supportive tool, not a replacement for expert medical assessment
• Regularly evaluate performance on new datasets
• Be aware of potential demographic or contextual biases in the predictions

How to Get Started with the Model

from transformers import AutoModelForSequenceClassification, AutoTokenizer
import torch

# Load the model and tokenizer
model = AutoModelForSequenceClassification.from_pretrained('model_path')
tokenizer = AutoTokenizer.from_pretrained('model_path')

# Example prediction function (similar to the provided get_predictions function)
def predict_icd9_codes(input_text, threshold=0.8):
    # Tokenize input
    inputs = tokenizer(input_text, return_tensors="pt", truncation=True, max_length=512, padding='max_length')
    
    # Get model predictions
    with torch.no_grad():
        outputs = model(**inputs)
        predictions = torch.sigmoid(outputs.logits)
        
    # Filter predictions above threshold
    predicted_codes = [model.config.id2label[i] for i in (predictions > threshold).nonzero()[:, 1]]
    
    return predicted_codes
