Working to turn around hospital drama (3)
I believe the answer is:
noh
'drama' is the definition.
(Noh or No is a Japanese masked drama)
'working to turn around hospital' is the wordplay.
'working' becomes 'on' (on can mean working or activated).
'to turn around' shows that the letters should be reversed in order (I've seen 'turning around' mean this).
'hospital' becomes 'H' (abbreviation for hospital on maps).
'on' backwards is 'no'.
'no'+'h'='NOH'
(Other definitions for noh that I've seen before include "Dramatic form" , "Drama in Japan" , "Traditional Japanese stage drama" , "Sort of drama" , "Japanese drama form" .)
