Reducing Hospital Readmissions With Predictive AI In Healthcare

Aivox partnered with Medi Bridge Health, a leading healthcare provider, to develop a predictive model capable of identifying high-risk patients based on electronic health records (EHR), lab data, and prior history. Our goal was to reduce hospital readmissions by enabling proactive care.

Project Overview

At Aivox, we collaborated with MediBridge Health to tackle a critical issue in the healthcare sector: unplanned patient readmissions. By developing a predictive AI model using real-time clinical data and historical records, we enabled the hospital to identify high-risk individuals before complications occurred.

The Solution

We built a machine learning model trained on anonymized EHR data, lab results, and patient notes. Key features included:

• Feature engineering from clinical records
• Gradient Boosting & Random Forest algorithms
• HIPAA-compliant data pipelines
• Real-time risk dashboards for physicians
• Integration with hospital’s internal portal

Technologies used

• Python – Core language for data processing and model development
• Scikit-learn & XGBoost – For predictive modeling and algorithm optimization
• Pandas & NumPy – For structured data manipulation and transformation
• Jupyter Note book – For exploratory data analysis and prototyping
• AWS Sage Maker – For model training, hosting, and deployment in a secure cloud environment
• PostgreSQL – To manage patient-related metadata and processed outputs
• Apache Airflow – For automating data pipelines and model retraining workflows

Key Benefits

• Reduced Readmissions by 22% Enabled proactive care with accurate patient risk scoring, decreasing unplanned hospital returns.
• Improved Early Intervention by 30% Gave doctors real-time insights to act sooner and prevent complications.
• 95%+ Model Accuracy Built a robust, validated machine learning model using real-world clinical data.
• Seamless System Integration Integrated easily into the hospital’s existing portal and workflows with minimal training required.
