Observation start timing relative to a fixed reference point


  • Variable --STTPT represents an applicant-defined fixed reference point that characterizes the start of an observation. Allowable values for --STTPT are a description of or the date and/or time of the fixed reference time point. 
  • Variable --STRTPT represents the start of an observation relative to a reference time point represented in --STTPT. Allowable values are that an observation can:

    Observation end timing relative to a fixed reference point

    • Variable --ENTPT represents an applicant-defined fixed reference point that characterizes the end of an observation. Allowable values for --ENTPT are a description of or the date and/or time of the fixed reference time point. 
    • Variable --ENRTPT represents the start of an observation relative to a reference time point represented in --ENTPT. Allowable values are that an observation can:
      • end "BEFORE" the reference point,
      • end "COINCIDENT" with the reference point,
      • end "AFTER" the reference point,
      • be known that it did not end but was "ONGOING", or
      • be "UNKNOWN" when it ended or if it was ongoing.
    3Planned intervals relative to a fixed reference point

    When instances of an activity are scheduled at planned time intervals relative to a fixed reference point (e.g., an exposure), the following timing variables will be used:

    VariableDescription of Use
    --TPTREFRepresents a description of the fixed reference point from which the planned observation will be made
    --RFTDTCRepresents the actual date/time of the value of --TPTREF
    --ELTM

    Represents the planned elapsed time from the fixed timepoint reference to the planned observation. The value of this variable is usually also reflected in the value of variable --TPT.

    --TPTRepresents the label for the time point relative to the value of --TPTREF
    --TPTNUMRepresents the order of time points represented in --TPT relative to the value of --TPTREF
