[Contract] 📂 EHR Interoperability Bridge

[salazarsebas]

🎯 Objective

Create a complete smart contract for ehr-interoperability-bridge that enables seamless data exchange between electronic health record (EHR) systems on the Stellar network using Soroban, ensuring secure and standardized data transfers while complying with healthcare interoperability standards like HL7 FHIR.

🏗 Contract Structure

ehr-interoperability-bridge/src/
  lib.rs                // Configuration and contract exports
  bridge.rs             // Core logic for EHR data bridging
  interoperability.rs   // Handling of data exchange protocols
  utils.rs              // Shared utilities for format conversions and validation
  Makefile              // Build and deployment automation
  README.md             // Contract documentation and usage instructions

🗂 Requirements

1. EHR Interoperability

   • Implement data exchange mechanisms compliant with standards like HL7 FHIR or SMART on FHIR.
   • Support secure data requests and transfers between EHR systems.
   • Enable format validation and conversion for compatibility across systems.

2. Healthcare-Specific Features

   • Consent-verified exchanges with role-based access for healthcare providers.
   • Integration hooks for linking to patient consent or medical records contracts.

3. Build and Test

   • Must successfully execute cargo build, stellar contract build, and cargo test.

---

📦 Key Data Structures

The contract will use maps to associate EHR system identifiers with supported data schemas and connection details. A request queue structure will manage pending data exchanges, each request including sender and receiver addresses, requested data types, and consent verification statuses for secure transfers.

🔑 Key Functions

• initialize() – Set up the bridge with registered EHR systems.
• request_data() – Initiate a data request from one EHR system to another.
• transfer_data() – Execute data transfer upon consent and validation.
• validate_format() – Validate and convert data to compatible formats.
• log_exchange() – Log successful data exchanges for auditing.

📌 Additional Notes

• Optimize storage to minimize transaction fees on Soroban for healthcare providers.
• Design for scalability to interconnect multiple EHR systems globally.
• Ensure secure data handling to comply with healthcare privacy regulations.
• Support future integration with standardized health APIs like FHIR.
• Include encryption mechanisms for data in transit within the bridge.
