Lab Test
Why do we need the result for uscheduled
instead of result for scheduled
• To use results for analysis as results for
scheduled visits (e.g. In summary statistics) =>
decision and derivation of stats >ADAM
• To use results as Baseline (e.g. Set up of
Baseline flag) => Company decision >SDTM IG
UC2 Pros & Cons
Arguments as
scheduled visits
Pros
Cons
•
•
•
•
no lost information
•
Arguments as
unscheduled visits
•
•
SV is cleaner
data traceability
•
•
Could overlap with the next visit
Difficulty in creation of SV domain
SDTM programming and mapping
more challenging (e.g. need to include
additional result identifier)
Potential issue with Open CDISC
Multiple unscheduled visits possible,
including SVDTC populated with the
same date
Challenges in further analysis
