client = OpenAIHealthcareClient()

query = HealthcareQuery(
    query="What are the differential diagnoses for chest pain?",
    domain=MedicalDomain.CARDIOLOGY,
    query_type=QueryType.DIAGNOSIS_SUPPORT,
    priority="high"
)

response = await client.process_healthcare_query(query)
print(f"Response: {response.response}")
print(f"Confidence: {response.confidence_score}")
print(f"Compliance approved: {response.compliance_approved}")
