Clinical Document Architecture (CDA)

Clinical Document Architecture (CDA) is a flexible XML-based clinical document architecture that uses the HL7 document markup standard that specifies the structure and semantics for the purpose of exchanging these documents. CDA documents use HL7 v3 Data Types and obtain their machine processable meaning from the HL7 Reference Information Model (RIM). Although the CDA is not a specific document, it can be used to express many types of documents.

CCD, Lab Report (HITSPC37), XDS-MS Discharge Summary (HITSP C48), and History and Physical (HITSP C84) are some of the types of CDA documents. CDA document data sections can be few or numerous and contain narrative text or structured data elements with text or code.

CONNECT

Is a software solution that supports health information exchange that implements 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. It enables public and private organizations to participate in the NHIN by leveraging their existing health information systems.

CONNECT Adapter

The portion of the CONNECT architecture that encapsulates the components most likely to be customized or replaced by an organization implementing CONNECT.

CONNECT Gateway

The portion of the CONNECT architecture that encapsulates the components most likely to be use as-is by an organization without modification. These components are primarily responsible for orchestrating information exchange with the NHIN.

Continuity of Care Document (CCD)

The Continuity of Care Document (CCD), in accordance with the ASTM E2369-05 Standard Specification for Continuity of Care Record (CCR), describes constraints on the HL7 Clinical Document Architecture, Release 2 (CDA) specification, and is intended as an alternate for the institutions or organizations committed to implementation of the HL7 Clinical Document Architecture specified in the ASTM ADJE2369 implementation. The CCD is just one of numerous types of CDA documents that can contain some of the same CCD sections, but can also contain different sections.

The Continuity of Care Record (CCR) shows one or more patient healthcare encounters, and is the core data set of the most relevant information facts in the patient's health records. It is used to support the patient's continuity of care, and provides a means for a healthcare practitioner, system, or setting to gather together a collection of all of the patient's pertinent data forward it to another practitioner, system, or setting.

Cross-Enterprise Document Media Interchange (XDM)

XDM uses a common file and directory structure over standard media to provide a document interchange that allows patients to carry medical documents using physical media. It also allows person-to-person email for the transfer of medical documents.

Health Information Exchange

Health Information Exchange is an entity that enables the movement of health-related data among entities within a state, a region, or a non-jurisdictional participant group, which might include "classic" regional health information organizations at regional and state levels, Health Information Organization integrated delivery systems and health plans, or health data banks that support health information exchange.

Health Information Organization

Health Information Organization is an organization that enables the movement of health-related data among entities, evolving as a replacement term for health information exchange or HIE. Healthcare Information Technology Standards Panel Or simply HITSP, a cooperative partnership between the public and private sectors formed and supported by ONC for the purpose of harmonizing and integrating standards that will meet clinical and business needs established by AHIC use cases for sharing information among organizations and systems.

Integrating the Healthcare Enterprise

Integrating the Healthcare Enterprise is an initiative by healthcare professionals and industry to improve the way computer systems in healthcare share information, promoting and coordinating the use of established standards such as DICOM and HL7 to address specific clinical need in support of optimal patient care. The Nationwide Health Information Network is being developed by ONC to provide a secure, nationwide, interoperable health information infrastructure that will connect providers, consumers, and others involved in supporting health and healthcare.

Nationwide Health Information Network

Nationwide Health Information Network is a set of standards, services and policies that enable secure health information exchange over the Internet. The network will provide a foundation for the exchange of health information across diverse entities, within communities and across the country, helping to achieve the goals of the HITECH Act. This critical part of the national health IT agenda will enable health information to follow the consumer, be available for clinical decision making, and support appropriate use of healthcare information beyond direct patient care so as to improve population health.

Nationwide Health Information Network Gateway

Within the CONNECT solution, the implementation of the core NHIN services and service interface specifications, comprising the CONNECT gateway and CONNECT adapter. The NHIN health information exchange or NHIE, a health information exchange that implements the NHIN architecture, processes, and procedures, is accredited as a participant of the NHIN.

Oracle Virtual Machine

Oracle Virtual Machine is a platform that provides a fully equipped environment for better leveraging the benefits of virtualization technology. Oracle VM enables you to deploy operating systems and application software within a supported virtualization environment.

Oracle Virtual Machine Manager

Oracle Virtual Machine Manager provides the user interface, which is a standard ADF (Application Development Framework) web application, to manage Oracle VM Servers. It manages virtual machine lifecycle, including creating virtual machines from installation media or from a virtual machine template, deleting, powering off, uploading, deployment and live migration of virtual machines. It manages resources, including ISO files, virtual machine templates, and sharable hard disks.

Oracle Virtual Machine Server

Oracle Virtual Machine Server allows a self-contained virtualization environment designed to provide a lightweight, secure, server-based platform for running virtual machines. Oracle VM Server is based upon an updated version of the underlying Xen hypervisor technology, and includes Oracle VM Agent.

Oracle Virtual Machine Template

Oracle Virtual Machine Template provides an innovative approach to deploying a fully configured software stack by offering pre-installed and pre-configured software images. Use of Oracle VM templates eliminates the installation and configuration costs, and reduces the ongoing maintenance costs helping organizations achieve faster time to market and lower cost of operations.

Security Assertion Markup Language

Security Assertion Markup Language is an XML-based standard for exchanging authentication and authorization data between security domains.

Web Services Description Language

Web Services Description Language is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information.

XML Schema

XML Schema is a means for defining the structure, content, and semantics of XML documents.
