Neat and tidy hospital attendant (7)
I believe the answer is:
orderly
I believe this is a double definition.
'neat and tidy' is the first definition.
(I've seen this before)
'hospital attendant' is the second definition.

(Other definitions for orderly that I've seen before include "Systematically, not haphazard" , "Neat, tidy; soldier" , "Hospital or military attendant" , "Batman" , "Well-behaved; hospital worker" .)
