Healthcare Technology & Interoperability Architecture

EA Horizon Healthcare Technology Architecture

At EA Horizon, Inc., our software engineering approach bridges advanced machine intelligence with resilient, open-standards healthcare infrastructure.

The EA Horizon platform serves as the foundational data and intelligence engine powering our applications, including our flagship product, Santé.

Architectural Principles

1. Data Liquidity via FHIR R4 & USCDI

Healthcare data has historically suffered from proprietary silos and non-standardized schemas. EA Horizon builds on open standards to guarantee true interoperability:

  • HL7 FHIR Release 4: Native support for FHIR resources including Patient, Encounter, Observation, Condition, DocumentReference, and CarePlan.
  • USCDI (United States Core Data for Interoperability): Standardized data classes enabling seamless compliance with ONC and CMS interoperability mandates.
  • SMART-on-FHIR Integration: Allows Santé to launch directly within clinical EHR portals (Epic Hyperspace, Cerner PowerChart) without context switching or secondary logins.

2. Privacy-Preserving AI & Clinical NLP

Clinical documentation is dense, unstructured, and sensitive. Our machine learning pipelines are designed specifically for clinical fidelity and patient privacy:

  • Zero Patient Data Leakage: AI models operate in isolated, zero-retention HIPAA-compliant enclaves. Model inference does not feed public foundation models.
  • Specialized Clinical Entity Recognition: Named entity recognition (NER) specifically trained on medical ontologies (SNOMED-CT, RxNorm, LOINC, ICD-10-CM).
  • Deterministic Verification Gateways: AI predictions are cross-referenced with hard-coded clinical rules and CMS guidelines before audit suggestions are presented to human reviewers.

3. Edge-Resilient, Offline-First Mobile Systems

Clinical care often takes place in rural communities, high-density residential buildings, or transit zones with intermittent connectivity.

  • Local SQLite & CRDT State: Clinicians can perform vital checks, capture electronic signatures, and record visit logs completely offline.
  • Conflict-Free Replication: When the device regains cellular or Wi-Fi connectivity, data merges deterministically with cloud backends using conflict-free replicated data structures.
  • Hardware-Backed Cryptography: Device-level biometric validation (FaceID, TouchID, Android Biometrics) secures patient health information stored locally.

Developer Ecosystem & Integrations

EA Horizon offers modern, developer-friendly interfaces for health IT departments and enterprise system integrators:

  • REST & GraphQL Endpoints: Rich querying capabilities for workforce scheduling, audit flags, and operational metrics.
  • Webhook Subscriptions: Real-time push notifications for shift status updates, visit verifications, and audit completion events.
  • Comprehensive SDKs: Python, TypeScript, and Go client libraries for rapid enterprise integration.
