🧠 PyBrain - Unified Healthcare Intelligence Platform

PyBrain is the intelligence layer of the BrainSAIT Healthcare Unification Platform, providing AI-powered data harmonization, clinical NLP, and decision support for building next-generation healthcare systems.

🚀 Features

• AI-Powered Data Harmonization: Automatically maps and transforms data across different healthcare standards
• Clinical NLP Engine: Extracts structured data from unstructured clinical notes with medical language understanding
• Federated Learning Framework: Enables privacy-preserving AI model training across healthcare institutions
• Real-time Decision Support: Provides evidence-based recommendations using ensemble AI models
• Predictive Analytics: Forecasts patient outcomes, resource needs, and population health trends

📦 Installation

pip install pybrain

For development:

pip install pybrain[dev]

For all ML features:

pip install pybrain[ml,nlp]

🔧 Quick Start

Basic Usage

from pybrain import AIEngine, DataHarmonizer

# Initialize AI engine
ai = AIEngine()

# Extract entities from clinical text
clinical_note = "Patient presents with type 2 diabetes, prescribed metformin 500mg twice daily"
entities = ai.extract_clinical_entities(clinical_note)
print(entities)
# {'conditions': ['Diabetes'], 'medications': ['Metformin'], ...}

# Harmonize HL7v2 data to FHIR
harmonizer = DataHarmonizer()
hl7_data = {
    "PID": {
        "5": {"1": "Smith", "2": "John"},
        "7": "19800415",
        "8": "M"
    }
}
fhir_patient = harmonizer.harmonize_to_fhir(hl7_data, "hl7v2", "Patient")

AI-Powered Risk Assessment

from pybrain import AIEngine, DecisionEngine

ai = AIEngine()
decision_engine = DecisionEngine()

# Patient data
patient_data = {
    "age": 65,
    "conditions": ["diabetes", "hypertension"],
    "medications": ["metformin", "lisinopril"],
    "bmi": 28.5
}

# Predict clinical risks
risk_score = ai.predict_risk_score(patient_data)
print(f"Overall risk score: {risk_score:.2f}")

# Get clinical recommendations
recommendations = decision_engine.evaluate_patient(patient_data)
print("Clinical alerts:", recommendations["alerts"])

Population Health Analytics

from pybrain import AnalyticsEngine

analytics = AnalyticsEngine()

# Analyze population trends
population_data = [
    {"patient": {"id": "1", "birthDate": "1960-01-01"}, "observations": [...]},
    {"patient": {"id": "2", "birthDate": "1975-05-15"}, "observations": [...]}
]

metrics = analytics.calculate_population_metrics(population_data)
print(f"High-risk patients: {metrics['risk_distribution']['high']}")
print(f"Recommendations: {metrics['recommendations']}")

CLI Usage

# Analyze clinical text
pybrain analyze -t "Patient has hypertension and diabetes"

# Harmonize data files
pybrain harmonize -i patient.json -f hl7v2 -r Patient -o patient_fhir.json

# Start API server
pybrain serve --port 8000

🤝 Integration with PyHeart

PyBrain works seamlessly with PyHeart for complete healthcare system unification:

from pybrain import AIEngine
from pyheart import FHIRClient

# Use PyHeart for data access
client = FHIRClient("https://fhir.example.com")
patient_data = client.get_patient("12345")

# Use PyBrain for intelligence
ai = AIEngine()
risk_score = ai.predict_risk_score(patient_data)

if risk_score > 0.8:
    print("High-risk patient - immediate intervention required")
