Dive</h2> <p>Healthcare interoperability remains one of the industry’s most persistent challenges. After implementing FHIR and HL7 solutions across multiple healthcare systems, I’ve learned valuable lessons about what works, what doesn’t, and why these standards matter more than ever.</p> <h3 id="why-healthcare-interoperability-matters">Why Healthcare Interoperability Matters</h3> <p>Every day, critical health information is trapped in silos:</p> <ul> <li>Lab results delayed because systems can’t communicate</li> <li>Duplicate tests ordered due to missing historical data</li> <li>Medication errors from incomplete medication lists</li> <li>Insurance claims rejected due to data format issues</li> </ul> <p>The cost? Lives affected, billions wasted, and physician frustration.</p> <h3 id="hl7-v2x-the-legacy-foundation">HL7 v2.x: The Legacy Foundation</h3> <p>HL7 v2.x has been the backbone of healthcare data exchange for decades.
