Very cool! Their Github profile seems to mostly be in other languages, e.g., they’ve got a deidentification library in Python (which makes sense since it’s NLP-based). I had to write one for our company, but it’s very different (built around maintaining consistent fake identities against real data and lacking NLP).
Can you mention any more about what kind of work they’re using Elixir for?
I only can google and send you links to what is publictly available at the moment, but one of the growing library of Elixir projects they use is at the heart of authorization mechanism: Shield.

Use Google Translate to get more details but this system basically answers the question of “if this user should have access to that patent’s data”. These security checks are being done throughout their systems, as you can imagine, and Elixir is at the core.
Edit: there is also one project I do have permission to share and it’s being used to report COVID-19 cases from care houses. Not much publictly facing but it’s an Elixir/Phoenix app with LiveView parts. My team at AmberBit helped build it.
Awesome, thanks for the info!
I also wrote Elixir code this year to send out alerts when patients from long-term care facilities get Covid tests or positive results after entering a hospital!
We use it heavily at Bridge Connector (also Nashville, but I and 75% of the Elixir devs are remote) where we’re building an “Integration PaaS” (think Zapier) for building healthcare integrations. We’ve been through a couple iterations to come up with a system we think can scale from a business perspective, but the current version seems like we’ve gotten it, and should just be a matter of incremental changes.
We actually use HCA’s HL7 library 
I’m really hoping FHIR gets used more widespread. It’s huge, but hopefully it makes integrations simpler.
Hehe awesome! We’re trying to probably solve similar issues in terms of high integration volume with Elixir!
Let me know if you need any features or have any suggestions for the HL7 library!
We also have an MLLP library on github (not Hex yet), not as well documented but it works.

And I’ve been writing a FHIR library – but got sidetracked on some other work before finishing it. I made the mistake of building it from the XSDs they provide. But it turns out they only have about 90% of the data needed to really generate validation code. You have to use the “structure definition” files instead. And the fact that FHIR breaks the JSON standard drove me CrAzY. Can’t use JSON.parse in a browser… can’t use Jason in Elixir (I forked it to make FHIR-Jason, couldn’t convince its author to violate the standard to support the “standard”…
You should visit our currently virtual NashFP (Nashville Functional Programming group) some time!
Nice. If anything comes to mind for the HL7 library I’ll let you know .
A previous healthcare shop I worked that had elixir (CoverMyMeds) used the google/fhir protobuf definitions in a small app a few years ago. I haven’t used them since then, and it was a pretty specific use-case (i.e. didn’t exercise a whole lot of the resources).
I know the state of the protobuf libraries has improved a good bit too. GitHub - elixir-protobuf/protobuf: A pure Elixir implementation of Google Protobuf. · GitHub was still pretty new, and exprotobuf/gpb generally worked but there were some validation annoyances in gpb that we kinda hacked around. No matter what though, some of the different ways of using Fhirpath, and references look like they’ll be a pain.
I’ll watch the twitter account for the next NashFP meeting. I went to the one back in February when I was in town, but haven’t attended any of the remote ones yet 
Just some extra information, there’s also the Protox library. This forum post gives more information about it:
https://forum.elixirforum.com/t/protox-a-100-conformant-protobuf-library
Hope it is helpful The maintainer @ahamez is also very nice, helpful and quick to respond.
Aaaaand Bridge Connector as a company doesn’t exist anymore 
We were building pretty awesome stuff but the CEO made some “questionable” choices, and the board.
I really want them to be able to sell their IP so at least someone can use it :-/
Current place, “prescribeFIT” is also healthcare + elixir working on remote patient monitoring combined with personal coaching and physician oversight. Majority of the existing code is an Express API and Angular 2 frontend, but the mandate is that whenever possible all new features will be in Elixir. I’ve been here about a month and have only written Elixir so far. Lots of Ecto.Multi at the moment and whenever we can finding ways to unwind poorly designed database schemas, or give ourselves more useful intermediate structures when we can’t.
Hi! Ratio PBC* has Elixir apps deployed in both NY and NJ for their pandemic response. I’d love to chat with other Elixir devs in the healthcare space! @darkmarmot I don’t know how many times I’ve recommended to colleagues the keynote of what HCA is doing in Elixir. It’s amazing.
* We spun out of Geometer, of which our former colleague Sax just gave a talk on one of our Elixir projects at Code Beam. https://www.youtube.com/watch?v=K15hC_aNf2w
My brother (family physician) and I started a direct primary care practice in South Carolina. We ended up building a lot of tools to run the practice and now sell them at https://scalpel.com/. We handle note taking, scheduling, internal/external communication, patient surveys, invoicing, online booking, and more. So there are at least two EMRs built in elixir. @darkmarmot let me know if you want to chat more about what we’re doing.
