Our Contemporary Open Source EHR

July 18, 2023

We are releasing Electronic Health Record (EHR) functionality module by module over the next twelve months, culminating in a fully production-ready open source and proprietary EHR.  The latest release includes authentication and authorization, appointments, and patient management.  It’s available on GitHub.

There are two parts to a Oystehr app.  Oystehr itself is a back-end cloud-service or “headless EHR,” including a secure FHIR API and datastore, authentication and authorization, and extensibility using Zambda Functions.

The second component is the front-end user interface you build on top of our back-end APIs and infrastructure.  To reduce effort and speed time to market, we want to provide not only the best health tech cloud service, but also production-ready open source Electronic Medical Records (EMR) and code samples that can be freely forked and modified by any organization using Oystehr.  

With that in mind, we regularly release front-end components and applications as reference implementations. 

Check out the source code of this week’s release on GitHub and take a look around this simple static React web application.  The key features of this sample are:

Authentication (and authorization)

zapEHR open source EHR console login

Appointments Tracker

PM Pediatric Care open source EHR appointments tracker

Patient Details

PM Pediatric Care open source EHR patient details

PM Pediatric Care used a custom version of the reference implementation to monitor appointment bookings from a behavioral health scheduling and intake application:

PM Pediatric Care open source EHR application

PM Pediatric Care augmented the reference implementation allowing Oystehr booked appointments and patient data to interface to external systems via HL7v2 ADT and SIU feeds. They use a Oystehr-based admin application to monitor, troubleshoot, and correct an unstable HL7v2 feed provided by an existing monolithic EHR.

The sample EHR codebase is available under the open source MIT-style license. Check it out on GitHub. If you have any questions or just need a little help getting the sample running, you can email us or join our Slack.
