Issue of having to stretch CDISC to accommodate the data. This may be happening because an Ebola outbreak has its own particularities. There is no controlled environment. The outbreak is the only occasion on which one can test drugs. This requires adapted protocols. To what extent does this affect what is recorded.
Suitability of CDISC as primary data dictionary is problematic. It is designed for clinical/drug trials, not for reporting medical/health incidents. It partially works for an outbreak iff there is an accompanying drug trial.
