Mahavir Dialysis Centre- Patient Discharge Summary using GenAI

AWS Lambda function is triggered to invoke a pre-deployed Large Language Model (LLM) endpoint for generating patient discharge summary reports. This Lambda function receives the processed data after the processing step, sends it to the LLM endpoint, and stores the generated reports in an Amazon S3 bucket. An EC2 instance with a FastAPI application serves as the user interface. Users can search for patient IDs, which triggers a pipeline to retrieve the corresponding patient's contents and generate the discharge report.

The Open-Source Large Language Model is fine-tuned on medical domain data and deployed as a SageMaker endpoint. This model is responsible for generating accurate and concise discharge summary reports based on the processed patient data received from the Lambda function. We chose Mistral 7B Instruct, an open-source Large Language Model (LLM), for our medical report analysis and discharge summary generation solution. This decision was driven by the model's capability to be effectively fine-tuned on medical domain data, enabling accurate comprehension of medical terminology and contextual nuances. Furthermore, Mistral 7B Instruct offers better customizability, seamless deployment flexibility on AWS SageMaker, and potential cost-effectiveness, making it a superior choice over proprietary models for this critical healthcare solution.
