Health Information Exchange Integration: A Technical Framework for Interoperability, Resilience, and Compliance

This technical framework documents practical patterns for building Health Information Exchange (HIE) platforms, drawing on experience from production systems processing millions of healthcare messages. The patterns address database contention in clustered deployments, audit logging performance, DNS failover for persistent connections, and data archival strategies balancing cost against compliance. Key contributions: (1) Schema partitioning eliminating write contention with 3x throughput improvement; (2) Asynchronous audit logging reducing latency from 50-200ms to 5-10ms; (3) Adaptive DNS failover reducing recovery time by 90%; (4) Time-based archival reducing storage costs by 80-95% while meeting HIPAA retention requirements.
