Oscar the Cat Predicts Patients' Deaths

It demonstrates the usage of tacit knowledge in medicine, in this particular instance in a cat.
It reminded me of tales of physicians/seers of yore who were said to have predicted not only their patient deaths but also their own deaths right down to the last minute and would generally choose to depart in style surrounded by their initially disbelieving relations.
Off course this may not be generalized to all physicians and this particular cat too needed to have been gifted to have found its place in nejm (unless he was as success theorists like to believe just being at the right place at the right time).
In recent times another mention of tacit knowledge in physicians (Greenhalgh T, British Journal of General Practice, May 2002 395) particularly with reference to predicting patient death has been made by a well known author physician and the paper also raises issues on EBM as EBM is definitely a way of reducing over-reliance on tacit knowledge in physicians:
That night, I went home and told my husband that I had
seen a man who was going to die. He did indeed die, four
days later, despite normal bloods and observation chart
throughout. Postmortem showed a strangulated volvulus.
This story raises a number of questions about the appropriate
clinical management of the patient in hospital, but I
include it here to show that intuitive insights are commonplace
in general practice, and they may or may not save
lives. They are rarely as impressive as the one I first heard
quoted by Professor Nigel Stott (and which I subsequently
analysed in detail1) from a GP in Cardiff: 'I got a call from a
lady saying her three-year-old daughter had had diarrhoea
and was behaving strangely. I knew the family well, and was
sufficiently concerned to break off my morning surgery and
visit immediately.'
This GP's hunch led him to diagnose correctly, and treat
successfully, a case of meningococcal meningitis on the
basis of two non-specific symptoms reported over the
phone — an estimated 'hit rate' for that particular GP of one
in 96 000 consultations, and a veritable tour de force for clinical
intuition. The intuitive judgements we make on a daily
basis in clinical practice are generally less dramatic but no
easier to explain on a rational level.
I wonder if EBMers would like to comment on this parallel movement and is there a possibility of developing an experimental design to study these phenomena in medicine?
