Nine Billion Faxes, or One Road

Healthcare sends an estimated nine billion faxes a year because every organization built its own private line to every other one — "a different dirt road for every car to everywhere else." A neutral hub says: connect once, reach everyone. Watch the difference.

Tangle, meet road

Each dot is a hospital. First, the world we have: everyone wiring to everyone, a private connection for every pair. Hit Pave the road and the tangle collapses to a single hub — the same reach, a fraction of the wiring. The counters underneath are the whole argument.

reach either way

The math: wiring every org to every other is N×(N−1)/2 private lines — 45 hospitals need 990. One neutral hub is N — just 45. Same reach; 20× less to build, break, and secure.

Hospitals are getting on it — fast, but not done

TEFCA — the federal "connect once, reach everyone" agreement — went live in late 2023. The 2024 ONC/AHA hospital survey captures an early rollout: a substantial group is live, and an even larger group is only planning. Look at the gap between the road that's paved and the road that's only planned:

461
hospitals live on TEFCA, 2024 survey
1,106
hospitals planning to join
88%
now in some health-info network
Live on TEFCA
20.5%
Planning to join
49.1%
In any network
88.2%

Share of 2,253 surveyed hospitals, 2024 wave. Nearly half are "planning" — a roadmap, not a road.

The critical lens. Two honest caveats before you cheer the curve. Planning isn't plumbing: the 49% "planning to join" is a self-reported intention, not a live connection — awareness ran ahead of exchange, and intent has a way of stalling. And the poster child is n=4. Delaware, whose neutral-hub bet inspired this whole story, reports zero hospitals live on TEFCA and all four planning — because its road is DHIN, a state exchange that predates the federal one. A great template can be true while the transplant is still hard.

Build for the person; the institutions plug themselves in.

The hub only wins because it's neutral — the one thing no single vendor can credibly be, since every vendor's incentive is to own the pipe, not share it. That's the opening.

When the connection becomes a public road, the point-to-point half of your product turns into free infrastructure. Don't mourn it — build the thing that only makes sense once "connect once, reach everyone" is true. The pearl from the hub's founder: build for the person, and every institution finds its own reason to show up.

MimiLabs report + SQL (query 6a58823653c953cfacc6047e) returns 2,253 hospitals across 51 jurisdictions: 461 live, 1,106 planning, and 1,988 in a health-information organization. These are self-reported survey indicators of awareness and intent, not measured live-exchange volume. "Nine billion faxes" is an industry estimate cited in the paired newsletter.
