Comprehensive department cuts in hospital (2-5)
I believe the answer is:
in-depth
'comprehensive' is the definition.
(I've seen this before)
'department cuts in hospital' is the wordplay.
'department' becomes 'dept'.
'cuts' is an insertion indicator (some letters cut their way into other letters).
'hospital' becomes 'H' (abbreviation for hospital on maps).
'in'+'h'='inh'
'dept' going into 'inh' is 'IN-DEPTH'.
(Other definitions for in-depth that I've seen before include "Full" , "With thorough and extensive investigation" , "Detailed (investigation)" , "Getting to the bottom of it" , "Detailed and thorough" .)
