OSEHRA led a special session on Open Source EHR Innovation during HIMSS 2014 on Sunday, February 23rd.  The first portion of the agenda highlighted innovations by providers such as Oroville Hospital, the State of North Carolina, and the College of St. Scholastica.  The latter portion of the session focused on the leadership and vision of the U.S. Department of Veterans Affairs.  VA provided a stellar team of briefers covering a range of topics that included VistA Evolution, Standardization, and Community Engagement.

Announcing the VistA Novo Project

A new OSEHRA open source project has just been launched to create an open source toolkit developers can use to build VistA-based applications using mainstream development environments. The project, called VistA Novo, will initially focus on supporting JavaScript (using node.js)—additional environments that could be supported in the future include Ruby on Rails and Python.
 

Visualizing worldwide installations of VistA

Working with data provided by Open Health News we developed a visualization of the worldwide installations of VistA.  The visualization was developed using Google's WebGL Globe open platform.  To view the visualization you'll need to use an updated version of Chrome, Safari or Firefox.  The visualization will not work in Internet Explorer.  To view the visualization, go to 

OSEHRA Automated Patching framework for VistA Development

Introduction:

KIDS (Kernal Installation & Distribution System) is a standard way of sending and loading patches and packages in VistA. Because the way patches are constructed and distributed, every patch might have specified dependencies and may only apply in a specific order.

A common problem related to VistA patching process is to figure out a right sequence to apply them in order, especially if a VistA instance is further behind the up-stream, as the dependency among KIDS builds can be very complicated.

VistA patch available from OSEHRA.

In late July, a possible VistA security vulnerability was discovered as part of an academic exercise at a major university.  The VISTA Expertise Network validated the vulnerability for some VistA configurations, and contacted OSEHRA to coordinate a community response.  A special open-source project group was formed.  Operating under non-disclosure agreements (industry best practice in handling zero-day exploits), OSEHRA members and collaborating partners (including VA and IHS) worked jointly to create and test an applicable patch.
