Preferred Label : Defined Observation Focal Date Range;
NCIt related terms : DefinedObservation.focalDateRange;
NCIt definition : The time period in which the observation result is held to be true, expressed either
as a simple date range or as an evaluable expression that references a study-defined
date or milestone.;
Alternative definition : BRIDG 3.0.3: The time period in which the observation result is held to be true, expressed
either as a simple date range or as an evaluable expression that references a study-defined
date or milestone. EXAMPLE(S): For a survey question, Have you traveled to Europe
between 1990 and 1999?, the focalDateRange would be January 1, 1990 to December 31,
1999.For the question, Have you smoked in the last 2 months, the focalDateRange would
be an expression referencing a variable that represents the PerformedObservation.actualDateRange
(a value yet to be defined) and a formula for the date range between when the question
is asked (PerformedObservation.actualDateRange.low) and 2 months prior (PerformedObservation.actualDateRange.low
- 2 months). NOTE(S): As an attribute with data type EXPRIVLTS.DATETIME, focalDateRange
can be used to express a simple date range such as January 1, 1990 to December 31,
1999 or a relative time expression that includes a variable that represents another
date in the model that is a study-defined anchor point. The other date may or may
not be known at the time the DefinedObservation is created, but will be known by the
time the PerformedObservation is created.; BRIDG 5.3: The time period in which the observation result is held to be true, expressed
