Out of the FHIR Podcast · New episodes weekly
I'm Eugene Vestel. Through consulting, open-source tools, and the Out of the FHIR podcast, I help teams navigate healthcare interoperability and turn data into outcomes.

What “quality measurement” looks like when it stops being a slide.

Standards
I hired and led b.well Connected Health's first FHIR team, stood up Analytics on FHIR there, and mapped the data for the interoperability platform now behind Samsung Health and Fitbit's medical records. The standards work below is where that experience keeps getting tested against other implementers.

Open Source
A guardrail layer between AI agents and health data, a personal care agent built on top of it, and an open corpus of the quality measures the whole industry keeps rewriting from scratch. All open, all running.
A security layer between AI agents and clinical data. Redacts PHI on every read, enforces multi-step human approval for clinical writes — proposal, permission evaluation, HMAC confirmation, immutable audit log — and keeps your health agent interactions HIPAA-compliant.
Spin up a personal health agent in under a minute. Every read redacted, every access audited, every action approved by you — guardrailed by HealthClaw. This is what the guardrail layer looks like once a person is actually using it.
An open, MIT-licensed corpus of healthcare quality measures with verified provenance, plus a typed record of what implementers have actually learned about each one. CQL and SQL alongside the measure, not buried in a PDF.
An ongoing analysis of the CMS health tech ecosystem and the national provider directory modernization effort. Mapping the players, the standards, and the FHIR-based architecture behind the next-generation healthcare directory.

Advisory
I advise healthcare organizations on FHIR implementation strategy, data architecture, quality measurement, and AI readiness. Whether you're starting your FHIR journey or optimizing an existing implementation, I can help you move faster and avoid common pitfalls.
