Methodical male hospital attendant . . . (7)
I believe the answer is:
orderly
I believe this is a double definition.
'methodical' is the first definition.
(I've seen this in another clue)
'male hospital attendant' is the second definition.
(hospital orderlies are typically male)
(Other definitions for orderly that I've seen before include "Soldier with special duties - hospital attendant" , "Neatly arranged; hospital attendant" , "Well-regulated" , "Methodical, like soldier servant" , "Tidy officer's attendant" .)
