A fine period at hospital -- result! (9)
I believe the answer is:
aftermath
'result' is the definition.
(aftermath is a kind of result)
'a fine period at hospital' is the wordplay.
'a fine' becomes 'af' (I've seen this in other clues).
'period' becomes 'term' (term is a kind of period**).
'hospital' becomes 'h'.
'af'+'term'+'at'+'h'='AFTERMATH'
(Other definitions for aftermath that I've seen before include "Consequence of an event, situation that follows" , "Second possible harvest" , "Consequences of a bad event" , "Wake" , "Sequel" .)
