Despite continuous development of, and the quarterly updates to, CDISC Controlled Terminology, there is still a need for study-specific extensions to standard codelists. Often, extensions to standard terminology are incorrect. For example, some users falsely believe that any new terms can be added to an extensible codelist and related data validation is not needed if new terms are listed in the define.xml.
In this webinar, Sergiy Sirichenko will summarize industry metrics across many studies and sponsors to produce an overall picture of CDISC Controlled Terminology utilization. He will review common issues with implementation of controlled terminology and reinforce best practices for extending standard codelists.
