Hospital eradicating first sign of unwanted rash (8)
I believe the answer is:
heedless
'rash' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for heedless that I've seen before include "Paying no attention, to advice or danger" , "Rash" , "Without caution" , "Led Hesse (anag)" , "Taking no notice" .)
