Just for clarity: statistics were not used in the Letby prosecution. The problem with Letby is that a serial killer was able to hide because finding a rare event (a member of staff murdering multiple babies) is hard to do in the noise (the mish mash of data available). Currently the English NHS is moving away from SIRI (Serious Incident Requiring Investigation) to PSIRF (Patient Safety Incident Response Framework) which focuses a lot more on "no blame" and "open culture", so it's important that NHS Trusts get the stats right to be able to detect and understand these very rare events. |

I was going to say that this is the second time I see someone in this thread claim this, but I noticed the other comment is also from your account:

As I say in that other comment, statistics were used in Lucy Letby's trial, in the form of the staff duty roster spreadsheet that the prosecution showed to the jurors to convince them that Lucy Letby was a "common denominator" in all the suspicious incidents.
