Healthcare Patient Analytics: Predictive Modeling Case

Use healthcare data to predict patient readmission risks and optimize treatment protocols. Apply diagnostic and predictive analytics techniques.

## Background

A hospital network wants to reduce patient readmissions within 30 days of discharge. High readmission rates indicate potential quality issues and result in financial penalties.

## The Problem

Using historical patient data, you need to:
1. Identify high-risk patients
2. Understand factors contributing to readmissions
3. Build a predictive model
4. Create a monitoring dashboard

## Data Available

- Patient demographics (age, gender, location)
- Medical history (diagnoses, procedures, medications)
- Admission details (reason, duration, department)
- Discharge information (status, follow-up plans)
- Readmission flags (within 30 days)

## Analytics Approach

### Phase 1: Descriptive
- Readmission rates by department
- Patient demographics analysis
- Common diagnoses among readmitted patients

### Phase 2: Diagnostic
- Why are certain patients readmitted?
- Correlation between length of stay and readmission
- Impact of follow-up care compliance

### Phase 3: Predictive
- Build classification model (readmit vs not readmit)
- Identify top risk factors
- Calculate risk scores for current patients

### Phase 4: Prescriptive
- Recommend interventions for high-risk patients
- Optimize discharge planning
- Suggest follow-up protocols

## Deliverables
