A standard, and the people who gave it away

The work begins
in 1987 — not with me.

Before there was a single interface to deliver, a small group of people decided a hospital’s data should belong to no one company. Everything HL7 Interfacing has built — 200+ interfaces across 20+ states — stands on what they chose to give away.

Read the lineage

HL7 was never just a message format. It was healthcare’s agreement to keep systems speaking when care depended on it.

The storm that started a standard

At the Hospital of the University of Pennsylvania, during what Ed Hammond later called the worst electrical storm he’d ever seen, a group of hospital CIOs, vendors, and engineers gathered with one goal: build a standard simple enough to implement immediately.

The catalyst was real pain. Sam Schultz, HUP’s chief information officer, had learned the hard way that connecting clinical systems got more expensive and more brittle by the day. Every interface was bespoke. Nothing was repeatable.

Don Simborg gave the protocol away

The seed was the StatLAN protocol, born at UC San Francisco and commercialized by Simborg Systems. It would have been easy to keep it proprietary — a competitive moat.

Instead, Donald W. Simborg put StatLAN into the public domain and pushed to create a neutral standards body to carry it forward. That act of generosity — choosing the commons over the moat — is the reason the rest of this story is possible.

In 1989, when critics worried HL7 was too close to his own company, Simborg stepped down as chair. He let the standard outgrow him.

He gave away the one thing he could have owned. So the whole field could move.

The standard hardens into infrastructure

HL7 v2 arrived in 1988 — pipe-delimited, fast, immediately useful. ADT, orders, results. For the first time, an interface could be repeatable instead of reinvented.

Ed Hammond took the chair and professionalized the community: formal balloting, governance, and finally ANSI accreditation in 1994. A volunteer idea became national infrastructure.

Grahame Grieve writes FHIR after hours

Two decades on, the web had moved and healthcare hadn’t. Grahame Grieve — an HL7 veteran later called “the father of FHIR” — began writing “Resources for Health” outside the hours of his day job, after a family health emergency showed him how fragmented care really was.

His insight: stop sending rigid messages, start exposing small modular resources — Patient, Observation, Encounter — over plain REST and JSON, the same web every developer already knew. Open-licensed, by design.

FHIR R4 — the foundation goes normative

With R4, the core resources stabilized into a normative standard you could build a business on without fear of the ground shifting. Patient. Condition. Observation. The vocabulary of modern interoperability was set.

This is the platform. Theirs, not mine. What follows is the engineer who bound his whole career to it — the old standard and the new alike.

A human story in segments

An HL7 message looks like delimiters. Inside, it’s a patient.

MSH, PID, PV1, ORC, OBR, OBX — pipes and fields. The genius of HL7 v2 was that it made healthcare operations computable without forgetting the workflow underneath: a patient arriving, an order placed, a result returning.

MSHWho sent it, who receives it, and what event just happened.
PIDWho the patient is.
PV1Where they are in the care journey.
ORCWhat was ordered.
OBRWhat test or observation was requested.
OBXWhat result came back.
Behind every pipe is a handoff. Behind every handoff is a patient, a clinician, and a workflow that has to keep moving.
Now — the work continues

Asmir Hasanbegovic — I learned the standard end to end

I started where everyone starts now: on FHIR — REST, JSON, resources, the modern face of everything Grahame Grieve set in motion. I could have stayed there. Most do.

So I went back to the foundation: back to Simborg’s commons, back to v2 — ADT, ORM, ORU, the pipe-delimited messages that still carry most of the clinical data moving in this country. I learned the standard from the 1987 storm forward, then went and delivered it: 200+ HL7 and FHIR interfaces across 20+ states and 17 EMR platforms, including VA and DoD ecosystems, on Mirth Connect, Corepoint, and Epic Bridges.

That is the throughline. From a 1987 ADT message to a FHIR R4 resource served over OAuth, there is no layer of this standard I haven’t shipped in production — old and new are the same craft to me.

I didn’t pick a side of the standard. I learned all of it — because a patient doesn’t care which version moved their data.

HL7 Interfacing Inc.

Founded in New York, 2022 — built in the hardest rooms in healthcare.

HL7 Interfacing Inc. was incorporated in New York in 2022 — not to chase logos, but to do the work most integrators avoid: the VA, the DoD, and international health systems where the network is unreliable, the stakes are lives, and the standard is the one thing in the room everyone agrees on.

The path ran from federal interoperability — VA and DoD ecosystems, where a single mismatched field is a patient-safety event — outward to international clients who needed that same rigor under far harder conditions.

2022 · Ukraine

The same year the company was formed, we interfaced for humanitarian teams sending aid into Ukraine — building the pipes that captured retina scans of the wounded and turned them into remote patient care delivered off those scans, when no clinician could be in the room.

That is what the standard is for. Not compliance, not a checkbox — a wounded person getting care because their data could move when they couldn’t.

Where the work landed

228 labs, mapped to where they actually are.

At 21, finishing my bachelor’s, I taught myself the APIs and ran 20 lab interfaces concurrently — then brought 228 labs into production as the sole interface analyst.

Now — the puzzle

Now I’m using the standard to solve the hardest puzzle in healthcare.

Every interface was preparation for this: taking the same FHIR R4 resources the founders built, and using them to match real patients to the trials that could change their lives. Every point on the globe is a live recruiting site, geolocated — drawn from the same database that powers asmirhasanbegovic.com.

The same mindset, carried forward

I didn’t just inherit their standard. I inherited how they thought.

Don Simborg · 1985
He put StatLAN into the public domain because a proprietary protocol wasn’t going to survive — healthcare needed something open, or nothing would connect at all.
My version of that same bet: using AI to drive healthcare SaaS license costs down, so the value flows to the organizations and the patients — not into a moat. Open beats owned. It did in 1987, and it still does.
Grahame Grieve · FHIR
His rule for FHIR was the 80/20: nail the part everyone agrees on, keep it simple and stable, and leave a clean way to extend for the rest. Free the health data.
That is exactly how I build a clinical-trial match — solve the 80% of eligibility that’s real and structured on FHIR R4, extend cleanly for the edge cases, and never let perfect become the enemy of a patient getting matched.
Ed Hammond · the long game
He spent decades turning a volunteer idea into governed, accredited national infrastructure — patient, durable, unglamorous work that outlived every hype cycle.
It’s why I went back to v2 instead of chasing only the new thing — and why I want to put real EMR systems in front of the developing world. The standard only matters if it actually reaches the bedside.
