Definition of Terms-


Concepts

A locution or word given to represent a numbe= r of different items in the i2b2 realm. These items can include terms, prov= iders and codes from standardized coding systems.

CRC

Clinical Research Chart. Also referred to as = the Data Repository Cell.

Drag and Drop

Phrase used to describe the action of moving = or copying items (queries, patient sets, etc.) from one location to another= .
"Drag" is done by clicking on = the item to be moved and while holding down the button on the mouse, move t= he mouse and in essence the item to the area on the screen in which you wan= t to place it.
"Drop" is the act= ion of releasing the button and placing the item in the new location.

Draggable Item

Only certain items can be "dragged" to anothe= r location (see drag and drop definition).

Encounter

This represents a "session' where observation= s were made. This "session" can involve a patient directly such as a visit = to a doctor's office, or it can involve the patient indirectly such as runn= ing several tests on a tube of the patient's blood. Encounters, Events, and Visits are al synonyms.

Events

This represents a "session' where observation= s were made. This "session" can involve a patient directly such as a visit = to a doctor's office, or it can involve the patient indirectly such as runn= ing several tests on a tube of the patient's blood. Encounters, Events, and Visits are al synonyms.

Group Template

A grouping of query items. It is also known a= s a panel. See panel for definition.

Item

This is a subsection for a panel in query= definition xml. This represents metadata constraints like concept key= , concept name, hlevel, modifier, etc.

NLP

Natural Language Processing = is a core cell in the i2b2 hive. It is an AI service, which extracts differ= ent concepts from patient notes.

Observations

Observations are collections of phenotypic da= ta and may contain values associated with a concept, such as a value of the= systolic blood pressure.

Observation Fact

The observation fact table represents the "fa= ct" table of the RPDR Star Schema. The fact table= can contain values associated with the concept, such as a value of the sys= tolic blood pressure.

Observers

The individual or item making the observation= .

Panel

This is one of the sections in the query = definition xml. Query Panel encloses a group of query items and contai= ns constraints like inversion and total occurrences.

patient_coll

Patient collection

Patient Data Object

A container of patient's visits, provider and= observation facts.

Patient Identifier

A unique code assigned to a patient that link= s the patient and the clinical data.

Patient Number

An internal number in the CRC that is assigne= d to the patient. These numbers should not be modified.

Patient Set

A collection of patients which the researcher= is interested in for a particular study. Patient set is an ordered collect= ion of patient numbers that should not be modified. The order is the set is= maintained all the time.

PID

Patient Identifier. See Patient Identifie= r for definition.

PDO

Patient Data Object. See Patient Data Obj= ect for definition.

Previous Query

Once a user runs a query it is stored as a "<= em>query master" and it becomes the first level on the query tree. The= se queries can be accessed via the Previous Query View.

Query

Mechanism for getting information from the da= tabase. Consists of concepts that are used as the search criteria to specif= y or narrow the results returned.

Query Definition

Contains all the outer tag information where = each group is represented in a query as panels.

Visit

This represents a "session' where observation= s were made. This "session" can involve a patient directly such as a visit = to a doctor's office, or it can involve the patient indirectly such as runn= ing several tests on a tube of the patient's blood. Encounters, Events, and Visits are al synonyms.

XML_RESULTS

The returned data from a query that is in xml= format.
