Decline brought surgical procedure and occupational therapy (2,2,3)
I believe the answer is:
go to pot
'decline' is the definition.
(I've seen this before)
'brought surgical procedure and occupational therapy' is the wordplay.
'brought' becomes 'got' ('get' can be a synonym of 'bring').
'surgical procedure' becomes 'op' (short for operation).
'and' is a charade indicator (letters next to each other).
'occupational therapy' becomes 'ot' (abbreviation for occupational therapy).
'got'+'op'+'ot'='GO TO POT'
(Other definitions for go to pot that I've seen before include "Fall into ruin" , "Become ruined" , "Approach snooker table" , "Tea bags will" , "Decline" .)
