A Privacy-First Approach to Health Data Integration Introduction The healthcare sector is on the cusp of a massive transformation, spurred by breakthroughs in generative AI, real-time health monitoring, and federated data infrastructure. As companies like OpenAI and Anthropic introduce clinical-grade capabilities into large language models (LLMs), the prospect of AI-assisted diagnostics, treatment planning, and patient support is no longer a distant vision. But with this innovation comes a deep concern:

Public Facing PR post The recent announcements from OpenAI and Claude around healthcare signal a growing intersection of AI innovation and patient privacy. As more AI services enter the clinical space, the need for a secure, patient-centered gateway is becoming urgent. While these models don’t yet offer public healthcare-specific APIs, demand is clearly building. In the meantime, existing APIs can be used to construct trust-preserving gateways that leverage AI without
