Leadership from chap, a shining example on hospital department (10)
I believe the answer is:
management
'leadership' is the definition.
(thesaurus)
'chap a shining example on hospital department' is the wordplay.
'chap' becomes 'man' (chap can mean a man).
'shining example' becomes 'gem' (I've seen this in another clue).
'on' means one lot of letters go next to another.
'hospital department' becomes 'ent' (abbreviation for Ear, Nose and Throat department).
'man'+'a'+'gem'+'ent'='MANAGEMENT'
'from' acts as a link.
(Other definitions for management that I've seen before include "Senior staff" , "Top part of organisation" , "Organisation heads" , "Administration" , "Business's upper echelons" .)
