Colchester Hospital in Essex has been placed in special measures after allegations staff were "bullied" into falsifying details about cancer waiting times.
The discrepancies were uncovered by the Care Quality Commission (CQC).
Health trust chiefs said they would now be helped to make further improvements.
Susie Fowler-Watt spoke to the chairman of the trust, Dr Sally Irvine, and asked her if thousands of patients could have been affected by the scandal.
