I work at a healthcare-related company, ScriptDrop that runs on Elixir. We coordinate couriers & pharmacies to get prescriptions delivered to patients. We don’t have a ton of open-source stuff at the moment, but there is this little library:

https://github.com/ScriptDrop/elixir_signed_overpunch

We use it to handle the “signed overpunch” format that NCPDP D.0 transmissions use for some fields.

We started out using Phoenix + Elixir as “fast Rails” with some extra binary-protocol-handling goodness for D.0. We’re now getting into more Elixir-y things with GenStateMachine.

I’ve never even heard of NCPDP! Will have to read up on it! Awesome!

I know Iora Health uses Elixir and Pill Pack was seriously considering it, but I don’t know if they eventually did.

They actually have a huge Elixir project in Ukraine, it was used to reform and digitalise the healthcare system.

It’s also open source https://github.com/edenlabllc/ehealth.api

Here’s a talk about it:

I have been working on EMR system Helium Health and whole application is written in Elixir. I also have been working on FHIR implementation in Elixir, but since then I have switched the job.

Cool. I had to do a little HL7 once, but so little that I could use very simple template strings. Nice to know this exists for more sophisticated needs.

Wow, an Elixir EMR! that rocks!

It seems that you guys have green wide eyes WOW about Elixir

I have used Elixir about 5 years, in which I use 2 years of Elixir and Phoenix in production for a Pharmacy-related company.
Good things I can say about Elixir:

• Good, simple parallel programming paradigm.
• Kind of stable and not much error prone.

Other than that, I wish I would have chosen Ruby or Python to implement my current production system all the time, all day, every day. Because of the nature of immutable languages, it is a super pain to implement complex business logics that require keeping states and passing states around.
Things I would have finished within one day in Ruby or Python take me about a week in Elixir. And trust me, I write Elixir nearly as well as I write Ruby, and much better than I write Python. Still Elixir productivity is nothing to write home about.

And despite whatever other people say that Elixir is close to Ruby, there is nothing further from the truth. I have worked with Elixir for 5 years, write Elixir code for production system everyday, and I still have to look in docs for function references. Elixir’s syntax is very counter-intuitive. Its syntax is just better than Erlang

This is an interesting perspective. For me it’s the opposite way around.

For low-level details of the code, mutability and direct pointer references make some things much easier (for example, everything having to do with graph algorithms, DOM manipulations, etc). I know because I’ve tried to do these things in Elixir and they are a pain.

However, for higher level program logic, elixir’s immutability seems like a positive thing, although probably less performant.

I know Nedap Healthcare from Netherlands is using Elixir extensively, which is a public knowledge as they posted ads and been hiring Elixir people and also have published open source Elixir code (so so am not breaching any NDA I may or may not have doing so ;)).
