CONNECT is an open source software solution that supports health information exchange – both locally and at the national level. CONNECT uses Nationwide Health Information Network (NHIN) standards and governance to make sure that health information exchanges are compatible with other exchanges being set up throughout the country.
OpenEMed is a set of distributed healthcare information service components built around the OMG distributed object specifications and the HL7 (and other) data standards and is written in Java for platform portability. We emphasize the interoperable service functionality that this approach provides in reducing the time it takes to build a healthcare related system. It is not intended as a turnkey system but rather a set of components that can be assembled and configured to meet a variety of tasks.
The Arden Syntax as a standardized language to represent medical knowledge can be used to express medical knowledge.
Arden2ByteCode is a open source compiler for the Arden Syntax. Arden2ByteCode runs on Java Virtual Machines (JVM) and translates Arden Syntax directly to Java bytecode (JBC)
executable on JVMs. It also serves as runtime environment for execution of the compiled bytecode.
The PUMA Repository (Pascal units for medical applications) is a collection of reusable source code for bioinformatics. It is compatible with Lazarus and Free Pascal, parts of the source code can also be used with Delphi and winsoft Pocket Studio.
Components of the PUMA repository include a unit converter for transforming instrumentation readouts consisting of a numerical value and a measurement unit, and an HL7 engine for reading, parsing, compiling and writing HL7 messages.
SPINA (structure parameter inference approach) is a method for calculating constant structure parameters of endocrine feedback control systems in vivo from hormone levels obtained from serum or plasma.
A first successful implementation applies to evaluation of thyroid function. It allows for calculating the thyroid's maximum secretory capacity (GT or SPINA-GT) and the sum activity of peripheral 5'-deiodinases (GD or SPINA-GD) from levels of TSH, (F)T4 and (F)T3 that have been determined once only (SPINA Thyr).
Mirth is an open source cross-platform HL7 interface engine that enables bi-directional sending of HL7 messages between systems and applications over multiple transports. It is divided in three subprojects:
- Mirth Connect: Specifically designed for HL7 message integration, Mirth Connect provides the necessary tools for developing, testing, deploying, and monitoring interfaces.
