My interpretation is that the suggestion is that- while they undoubtedly observed and recorded some kind of skin discolouration- they may have built it up into something more specific/meaningful, in the years since, than what it was at the time due to confirmation bias around the air embolism narrative.
well, this was Dr Harkness's clinical note
on the night E collapsed
: 'Sudden deterioration at 11.40pm, brady 80-90bpm, sats 60%, poor perfusion,
colour change over abdomen purple discoloured patches'. The note adds, after an improvement in sats, '
purple discolouration in abdomen remained', and a plan of action noted for E. (electronic evidence)
LL's note: 11.40pm became Bradycardiac,
purple band of discolouration over abdomen,...
A nursing colleague had referred to '
discoloured abdomen' in a retrospectively written note at 1.30am.
I don't think there was an air embolus narrative at the hospital.
Dr Harkness also testified he has not been in discussions with anyone in relation to these observations.
For baby B, this was the on-call consultant's note -
The court is shown clinical notes made by her, written retrospectively at 2.40am on
June 10, 2015.
She was called at home at 12.36am, and arrived at the neonatal unit at 12.50am.
She recorded Child B "went apnoeic [stopped breathing]", followed by "
suddenly purple blotching of body all over, with slowing of heart rate."The consultant says the 'purple blotching' would have been
the registrar's account of events,
relayed to her.The consultant noted, for her observation: "
Upon my arrival purple blotching right mid-abdomen and right hand." The baby was "pink and active".
The consultant's notes add: "Spoke to parents. "Purple discolouration almost resolved. "?? cause."
She tells the court: "I think this was something I was puzzled about, and wondering what it would be."
She says other causes were ruled out as such a rash had "come out of nowhere" and had "almost completely gone" a couple of hours later. The consultant says, from looking at her notes, she was "quite puzzled" by that as there were two question marks.The doctor says she was 'puzzled' by Child B's deterioration. Describing the 'rash' that covered her, she said: '
It was so florid, it came out of nowhere. One and a half hour's later it is completely gone'
Dr Evans said [...] his original conclusion was without knowing about the skin discolouration in Child A. I think this shows he hadn't even seen the statements made to the police when he made his diagnosis.
He adds that if you discover additional information, that "simply firms up your diagnosis".
I could go on, finding very similar witness statements for babies C and D.
And it's not just Dr Evans and Dr Bohin coming up with a narrative, Professor Arthurs also says the air on the x-rays available is consistent with air being administered and not consistent with death from natural causes or post mortem changes.
Seen in a cluster of sudden unexpected collapses in babies who were stable and showed no signs of slow deterioration, 'confirmation bias' is not a very convincing strategy, IMO
