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 a word).
'hospital' becomes 'H' (abbreviation for hospital).
'in'+'h'='inh'
'dept' inserted 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" .)
