Description: OpenCDS is a multi-institutional, collaborative effort to develop open-source, standards-based clinical decision support (CDS) components and resources that can be widely adopted to enable CDS at scale. OpenCDS provides a reference implementation of the Decision Support Service (DSS) standards adopted by the Health Level 7 (HL7) and Object Management Group (OMG) standards development organizations. The DSS standards specify a standard interface for providing clinical decision support as a software service, and is a part of a larger effort to standardize software service interfaces for health care known as the HL7-OMG Healthcare Services Specification Project. OpenCDS uses a flattened form of the Virtual Medical Record (vMR) internally as its data model. OpenCDS can also communicate with external systems using an XML form of the vMR. vMR is a standard HL7 data model optimized specifically for clinical decision support.

OpenCDS does not utilize a database. Any data generated by this technology is saved to the user`s local drive.
