Health Data Systems
A true longitudinal healthcare record including data from VA and non-VA sources. The health data system supports research and population analyses; facilitates Patient access to data; sharing of information across VHA; and improves data quality and data security.
The clinical data repository for HealtheVet-VistA. HDR II will store all nationalized, viewable, patient-centric clinical data for the VHA in support of longitudinal, patient-centric care.
The HDR Hx collects legacy VistA data from 128 VistA systems in at least four clinical domains. HDR Hx stores the data in a text “read only” format to accessible by the local VistA systems.
The pre-HDR II interim solution for nationalizing viewable, patient-centric clinical data. The HDR IMS will collect data from 128 VistA systems in at least four clinical domains from the point at which the data is standardized in the VistA system going forward. HDR IMS will ultimately be replaced by HDR II. Prior to the deployment of HDR II, HDR IMS will be a data provider to CDS.
A standardized messaging protocol that is common to medical applications.
The next generation of VistA provides enhanced flexibility for future healthcare and compliance with the One VA Enterprise Architecture. It enables seamless data sharing between all parts of VA to benefit Veterans and their families.
Health Information Architecture
A powerful, ultra-high performance object/relational persistence and query service for Java. It allows for the development of persistent classes following common Java idiom–including association, inheritance, polymorphism, composition, and the Java collections framework. The Query Language, designed as a “minimal” object-oriented extension to SQL, provides a bridge between the object and relational worlds. Also allows for the expression of queries using native SQL or Java-based Criteria and Example queries.
A VA Data Field used to indicate whether an item is considered “high-risk” to a patient and therefore requires follow-up or double-checks during administration.

A list of all active, recently discontinued, and expired prescriptions for a Patient.
Health Level Seven
An instruction not to dispense an “Active Order” until a specified date/time. The Hold is removed once the date/time is met. For doses, a user specifies how many doses to “Hold” and the system automatically calculates the date/time associated with the doses. A Patient’s “Active Orders” can also be automatically placed on “Hold” when there is a Patient movement event (i.e., admission, discharge, transfer, pass). In this case, the “Hold” is manually removed by an authorized user.

HealtheVet-VistA
A protein-carbohydrate solution. Electrolytes, fats, trace elements, and vitamins can be added. Since this solution generally provides all necessary nutrients, it is commonly referred to as Total Parenteral Nutrition (TPN). This solution provides all necessary nutrients parenterally.
A process of long-term feeding of a hyperal.
The basic language that is used to build hypertext documents on the World Wide Web. It is used in basic, plain ASCII-text documents, but when those documents are interpreted (or rendered) by a Web browser, the document can display formatted text, color, a variety of fonts, graphic images, special effects, hypertext jumps to other Internet locations, and information forms.
