Healthcare Patient Outcome Prediction Using Amazon HealthLake and Amazon SageMaker

Unnamed AWS healthcare customers developed a deep learning model to predict patient outcomes such as mortality within 90 days after ICU discharge by utilizing both structured and unstructured healthcare data. The solution used Amazon HealthLake to normalize and extract clinical data, combining embedding techniques for richer unstructured data representation. A custom convolutional neural network model was trained on Amazon SageMaker using TensorFlow containers. Visualization of results was provided using SHAP values for interpretability through a custom UI and API Gateway. This approach enabled improved healthcare provider decision-making and early patient intervention based on predictive insights.

  • 1Patient Outcome Prediction
  • 2Deep Learning
  • 3Model Interpretability
  • Healthcare providers face challenges in effectively using heterogeneous clinical data including structured and unstructured records to predict patient outcomes.
  • Interpreting complex prediction model results in an intuitive way to support clinical decisions is difficult.
  • Data from Amazon HealthLake was exported and transformed using AWS Glue and crawlers to create a queryable Data Catalog.
  • Deep learning models were trained on Amazon SageMaker to combine embeddings from unstructured data and structured clinical variables for accurate predictions.
  • An API Gateway and Lambda serverless functions were developed to deliver visual explanations of predictions via SHAP values in a web UI for model interpretability.
  • The model achieved an AUC of 0.82 and an F1 score of 0.74, indicating good predictive performance.
  • Healthcare providers can intervene earlier with patients at risk, improving care outcomes and reducing hospital readmissions.
  • Visualization of SHAP values helped clinical teams better understand model decisions and trust AI predictions.
Architecture

The architecture includes Amazon HealthLake for clinical data normalization, a data catalog with AWS Glue, model training and inference pipelines on Amazon SageMaker with TensorFlow, and visualization through Lambda and API Gateway for SHAP-based interpretability.
