Prescription Validation Integration

Integrate Oneliac's prescription validation service to securely validate prescriptions with drug interaction checking, eligibility verification, and pharmacy confirmation.

Overview

The prescription validator performs comprehensive validation:

• Drug interaction analysis
• Patient eligibility verification
• Cross-chain pharmacy confirmation via LayerZero
• Zero-knowledge proof generation

Drug Interaction Database

Oneliac includes an extensive drug interaction database:

from oneliac.prescriptions import DrugInteractionChecker

checker = DrugInteractionChecker()

interactions = checker.check_patient_interactions(
    patient_id="patient_abc123",
    new_medication="metformin_500mg",
    severity_filter="moderate"  # minor, moderate, severe
)

for interaction in interactions:
    print(f"{interaction.drug1} + {interaction.drug2}: {interaction.severity}")

Implementation Example

from oneliac.prescriptions import PrescriptionValidator

validator = PrescriptionValidator(
    api_key="sk_live_...",
    network="mainnet"
)

prescription = {
    "patient_id": "patient_abc123",
    "medications": [
        {
            "ndc_code": "0093-7651-56",
            "name": "Metformin",
            "strength": "500mg"
        }
    ],
    "provider_npi": "1234567890",
    "pharmacy_npi": "1111111111"
}

result = validator.validate(prescription)

if result.validation_status == "approved":
    print(f"Prescription approved: {result.prescription_id}")
    print(f"Pharmacy can fill on: {result.checks['pharmacy_confirmation']['estimated_availability']}")
elif result.validation_status == "requires_review":
    print("Manual review required")
else:
    print(f"Validation failed: {result.validation_status}")

LayerZero Cross-Chain Verification

Pharmacy confirmation across multiple blockchains:

from oneliac.prescriptions import CrossChainPharmacyVerifier

verifier = CrossChainPharmacyVerifier()

verification = verifier.verify_pharmacy(
    pharmacy_npi="1111111111",
    pharmacy_address="0x...",
    source_chain="solana",
    dest_chains=["ethereum", "polygon"]
)

if verification.confirmed_on_all_chains:
    print("Pharmacy verified across all chains")

Error Codes

Code	Description
INTERACTION_FOUND	Drug-drug interaction detected
CONTRAINDICATED	Medication contraindicated for patient
INELIGIBLE	Patient ineligible for medication
PHARMACY_ERROR	Pharmacy verification failed
PROOF_FAILED	ZK proof generation failed

Callbacks and Webhooks

Set up webhooks for prescription events:

validator.register_webhook(
    event="prescription.approved",
    url="https://your-system.com/webhooks/prescription"
)

Batch Validation

Validate multiple prescriptions efficiently:

prescriptions = [
    {"patient_id": "...", "medications": [...]},
    {"patient_id": "...", "medications": [...]},
]

results = validator.validate_batch(prescriptions)

Caching and Performance

Enable caching for faster validation:

result = validator.validate(
    prescription,
    cache=True,
    cache_ttl=3600  # 1 hour
)

Compliance

• NCPDP compliant
• HIPAA secure
• DEA controlled substance verification
• State pharmacy board regulations
