Colchester Hospital says it is not "working on the assumption" that one out of three cancer patients (approximately 2,000 a year) has had their records falsified, as claimed by The Observer newspaper.
Any figures quoted in the media about the number of patients who may have been affected are purely speculative.
We are determined to get to the bottom of all of the concerns and issues raised in the CQC report and we are already working closely with professional regulators, local GPs, North East Essex Clinical Commissioning Group, NHS England and Essex police to do so.
If there is any evidence that any of our staff have inappropriately adjusted and reported cancer figures, the Trust will take strong action in all cases...
Our priority is the safety and welfare of all cancer patients.
