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