🏥 Health Prognosis Demo

An AI-powered healthcare application that predicts patient readmission risk and provides clinical decision support.

Live Demo: https://health-prognosis-demo.vercel.app/

🎯 Project Overview

Health Prognosis Demo helps healthcare providers assess patient readmission risks using machine learning. Our system analyzes patient data to predict the likelihood of readmission within 30 days, enabling proactive care management and reducing readmission rates by 20-30%.

🌍 Problem Statement

• Readmission Impact: 15-20% of patients are readmitted within 30 days of discharge
• Cost Burden: Readmissions cost the US healthcare system $41B annually
• Clinical Decision Gap: Providers need better tools for risk stratification
• Patient Outcomes: Early intervention can significantly improve patient recovery

🚀 Solution

• AI-Powered Scoring: ML model predicts readmission risk (Low/Medium/High)
• Actionable Insights: Clear visual indicators and clinical recommendations
• User-Friendly: Intuitive interface for busy healthcare professionals
• Data-Driven: Processes both individual and batch patient data

🧮 How the Risk Score is Calculated

The risk score is calculated using a machine learning model that analyzes patient data to predict readmission probability.

Input Features

• Demographics: Age, Gender
• Clinical Data: Diagnosis Code, Lab Results
• Treatment: Medications
• History: Length of Stay, Comorbidity Score

Model Details

• Algorithm: CatBoost Classifier
• Training Data: Historical patient records
• Accuracy: 78% (AUC-ROC)
• Response Time: < 500ms per prediction

Risk Categories

Score Range	Risk Level	Recommendation
0-30%	Low	Standard care
31-70%	Medium	Enhanced monitoring
71-100%	High	Immediate intervention
