Present minutes before hospital department's medical attention (9)
I believe the answer is:
treatment
'medical attention' is the definition.
(I've seen this before)
'present minutes before hospital department's' is the wordplay.
'present' becomes 'treat' (treating is a kind of presenting**).
'minutes' becomes 'm'.
'before' means one lot of letters go next to another.
'hospital department' becomes 'ent'.
'treat'+'m'+'ent'='TREATMENT'
(Other definitions for treatment that I've seen before include "Care provided to improve a situation" , "Method of handling or healing" , "Handling - therapy" , "Maintenance work" , "The handling or management of something" .)
