Variables AESTDT AESTDT_P AESTOT AEENDT AEENDT_P AEENST in AE rawdata

[DmytroYermak]

Hi all,

Do anybody ever faced this variables: AESTDT_P     AEENDT_P   ?

Another variables mean:

SAS Output

AESTDT - start date of AE

AESTDT_P - ?

AESTOT - start time of AE

AEENDT - end date of AE

AEENDT_P - ?

AEENST - end date of AE

Could you please explain what do these two  (AESTDT_P     AEENDT_P ) mean? Thank you!

You should check with the data source. SAS doesn't "pick" variable names generally.

Actually I have not found this variable in a CRF but it is present in AE-SDTM specification. The length is $1. Very strange case...

In Clinical, when a patient doesn't remembers the exact start and end date of Adverse Event. In that case a partial start and end date is captured as provided by the patient.

So assuming from the given variables names, AESTDT_P and AEENDT_P  are the variables containing the partial dates w.r.t. AESTDT and AEENDT.
