This is where it was discussed in court, with Nick Johnson cross-examining Lucy Letby for the prosecution. He makes a bit of a meal of the timing and that seems to have caused some confusion in the press, with some suggesting this was about baby O.
NJ: Let's go to the Datix form now please. This is the Datix form for the child JA. There we see that you made this report at 20:55 on June 30th 2016.
LL: No I believe the date the open date when I started the form is July 1st.
NJ: I see, all right, so the incident is the 30th
LL: From reading that I would say yes.
NJ: So just to put that in context this is an incident being recorded four days after the text that we were just looking at when I was suggesting you had your thinking cap on relating to an incident that happened three days after that text.
Okay so if we can go back to the form in general please, Mr Murphy. A clinical incident was how you described it and equipment problem malfunction or unavailable is that right?
LL: Yes
NJ: Is this your selection from the drop down menu?
LL: Yes
NJ: No harm, low potential harm.
What you then record is that on the 30th as you said at 15:00 hours so let's just put that into context please this is five hours or so before the end of the day shift that you were on.
LL: If I was working that shift, yes.
NJ: Well, you're reporting an incident that's happened on a shift, aren't you?
LL: Yes.
NJ: Yes. So five hours before the end of the shift, about seven hours after the start of the shift.
LL: Yes.
NJ: Yes. Yes. So seven hours after you first met this child, JA.
LL: Yes, if I was looking after JA, yes.
NJ: What you say is, upon administering IV medication via UVC, the port on one of the lumens was noted not to have a bung on the end, and was therefore open.
LL: Yes
And this is the presentation of Lucy Letby's text messages about it later on:
Monday the 4th and Tuesday the 5th were annual leave days and we come next to a message sent at 14.16 on Tuesday the 5th by [Nurse E] to Lucy Letby:
"I only found out yest about the business with J[A]'s UVC."
A. Lucy Letby replied:
"Really? I thought they were going to take it straight out. Did he still have it in?"
Q. "Yes."
Then she says:
"Mark came in chatting to me at the start of last night's shift and said [redacted] needs LL. L as soon as UVC been in nearly 2 weeks and he said something about J[A]'s already being changed and I said it hadn't and he told me about the open port."
A. Lucy Letby replied to [Nurse E]:
"Jeez, well, that was on Thursday. [Dr A] didn't have time to look for access in the evening so had to label it and not use port overnight and they would sort it the next day. Abby new."
Q. From [Nurse E]:
"I handed over to Abby this morning and she said she knew nothing about it being changed and why would it be."
A. And Lucy Letby replied:
"Bloody hell. Thank goodness I did a Datix."
Q. "Did you? Good.
Well, when that gets looked into they'll see it never got changed."
A. Lucy Letby replied:
"I told her about it that night. Yes, because thought it's a massive infection risk and risk of air embolism. Don't know how long it had been like that."
So - she reported an open bung and discussed it with a friend after the friend brought it up. Nobody seems to dispute that any of this happened - the prosecution just decided to view her reporting it as some sort of attempt to smear the unit.
