Two entries catch what one might miss
Independent, blinded entry means a single transcription error is caught by comparison rather than going unnoticed.
What's included
How paper CRFs get entered and verified
- Key fields entered independently by two separate data entry staff, blinded to each other's input
- Automated comparison of the two entries, field by field, to catch transcription mismatches
- Any discrepancy between entries routed into query management and resolution rather than resolved informally
- Entry conventions and field priority set out in the data management plan, so second-pass entry is consistent across staff
- Reconciled, verified data logged with a traceable record of what was corrected and when
Discrepancies become queries
Any mismatch is routed into the same query management process used for every other discrepancy.
