Respected user, hi I evaluated your query thoroughly.
* Sound clinician doesn`t require / is not dependant upon investigations or
work up.
* Most common causative organisms are E.coli(50%),
gram -ve species ( Klebsiella, proteus,
enterobacter ,
pseudomonas (40%)
grm +ve ( E.faecalis, S.saprophyticus,
S. aureus ) - 10%
Thus clinical treatment starts and target most common susceptible organisms
even though culture is negative.
Best clinicians always treat patient on his judgement rather than relying
totally on mechanical parameters.
Hope this clears your query.
