Review of international nursing home brings alarm (5)
I believe the answer is:
panic
'alarm' is the definition.
(alarm can mean panic or worry)
'review of international nursing home' is the wordplay.
'review of' says the letters should be written in reverse.
'international' becomes 'cap' (sportsperson who competes internationally).
'nursing' is an insertion indicator.
'home' becomes 'in' (to be in is to be (at) home).
'cap' placed around 'in' is 'cinap'.
'cinap' back-to-front is 'PANIC'.
'brings' is the link.
(Other definitions for panic that I've seen before include "Blind fear" , "Flap" , "general alarm" , "Great consternation" , "Overwhelming terror" .)
