Tidy hospital employee (7)
I believe the answer is:
orderly
This clue is a double definition.
'tidy' is the first definition.
(similar in meaning)
'hospital employee' is the second definition.
(I've seen this in another clue)
(Other definitions for orderly that I've seen before include "Well-behaved; hospital worker" , "Well-regulated" , "Hospital attendant - neat" , "Well-behaved -- soldier attending to a superior officer" , "Officer's assistant" .)
