Strategy and Solutions

Zymr developed a Python-based ML engine using scikit-learn, Pandas, and NumPy to train a binary classifier on historical EMR datasets. We exposed the model through a FastAPI microservice, enabling real-time scoring and integration into hospital dashboards. Feature importance was visualized using SHAP to ensure explainability for clinical teams. A retraining pipeline was implemented using Airflow to update the model weekly.

Predicting Hospital Readmissions with Python ML

About the Client

A U.S.-based healthtech SaaS provider serving hospitals and clinics with EMR-integrated platforms. The client aimed to leverage machine learning to predict patient readmission risk and optimize discharge planning.

Key Outcomes

Integrated the ML engine with three EMR systems via FHIR APIs
Deployed real-time scoring with sub-second latency using FastAPI on AWS Lambda

Business Challenges

Hospitals faced rising penalties due to high readmission rates under CMS guidelines. The client needed a predictive model capable of learning from EMR data, including clinical notes, vitals, and medication histories. The existing system lacked infrastructure for real-time prediction and model retraining.

Business Impacts / Key Results Achieved

The model achieved 87% prediction accuracy and enabled proactive interventions that reduced hospital readmissions by 28% within six months. Hospital partners reported improved care planning and better patient outcomes.
