What is OSEHRA VistA?
OSEHRA VistA is a set of software components designed to support open source EHR solutions based upon the award-winning VistA EHR developed by the US Department of Veterans Affairs. OSEHRA VistA consists of FOIA VistA, replacing redacted code, and adding innovations and established software from the community that has been certified by OSEHRA. OSEHRA VistA lays the groundwork for enhanced collaboration and accelerated innovation among the many members of the open source electronic health record (EHR) community. Implementers of OSEHRA VistA will reap the benefits of a common open source baseline while adding their own value to produce production EHR solutions.
The new product set is the result of more than five years of community collaboration. OSEHRA VistA is not intended as a complete EHR solution, but as a baseline of open source community code that will strengthen all VistA-based EHR implementations and accelerate community innovation. Until now, the open source VistA community has been unable to realize the full benefit of open source development. While many vendors and healthcare providers have utilized VA code or derivative versions of VistA, prior to the initiation of this project, code sharing and collaborative development among the community members have been handicapped by the lack of a common baseline with a known licensing model. The emergence of OSEHRA VistA will allow all community members to share portions of their code.
OSEHRA VistA Core
OSEHRA VistA Core provides a common underlying foundation for VistA-based solution development. It is intentionally limited in size, and tightly controlled to ensure compatibility with the variety of VistA distributions (both current and future). Current core content includes:
OSEHRA Certified VistA Components
OSEHRA Certified VistA Components include various VistA packages that have been OSEHRA Certified (minumum OSEHRA Level-2). As part of this certification, these components have been certified as compatible with OSEHRA VistA Core, so that they can be easily implemented as part of any EHR solution utilizing that core. Certified components include:
- Appointment Postcard Notification Letter v4.0
- XU Digital Signature
- Problem List Refactoring
- OSEHRA Patch Module 2.5
- Inactive Allergies and Sign/Symptoms are selectable fix
- Problem List Infinite Loop when removing and re-adding a problem
- CPRS Medication Dialog Complex Order Fixes (slated for inclusion into FOIA VistA)
- Maternity Tracker Software (deployed in various regions in the VA--currently contracting for further enhancements)
- Auto Resize Margins to fit Terminal Size (slated for inclusion into FOIA VistA)
- Prostate Clinical Outlook Visualization System
The following have been OSEHRA Certified VistA Components that already made into FOIA VistA:
What does "Open Source" mean?
OSEHRA VistA is licensed under the Apache 2.0 Open Source License. That means the source code for the entire system is available to the public free of charge. Open Source enables adopters to easily obtain the code, use it, improve it, and share enhancements fluidly and freely with the rest of the Open Source Community through OSEHRA. In short, everyone benefits from the collective contributions to the shared code base.
