"The similarities between this young woman and [Alice Figueiredo] are startling in terms of presentation, age range, background," the email said.
It goes on to say while it appears there has been "some learning" since Alice's death, there was "significant evidence" that not all incidents were being properly reported.
The hospital used an NHS risk management system called Datix where incidents should be logged on the system to help identify risks and patterns of behaviour.
The report says during the time Alice was on the ward there were 81 incidents or near misses that met the criteria for being reported via Datix, but just 14 (17.2%) were logged on the system.
In the November case, there was also significant under-reporting. The report suggests that of 45 self-harm events involving the unidentified young woman, 27 do not appear on the risk management system, including the attempt to harm herself using a bin bag.
