Hi! Marijn.
No, no "national" code used by Consultants, just the personal phrases oft used by individuals.
"pleasant lady" is a compliment....why look for hidden meanings?
Some Consultants would say "Thank you for referring this old trout" others might say," he is the original Mr Magoo"...remember doctors are human and have human failings as anybody else and can get p.ssed off and this is reflected in their nomenclature sometimes.
Medicine is a different animal now, the patient's notes are not the property of the Health Authority, but of the patients themselves, so one has to be careful what one writes.
No Marijn.....no ulterior meaning or sinister connotations.
