Health check claimed to be mishandled (7)
I believe the answer is:
medical
'health check' is the definition.
(synonyms)
'claimed to be mishandled' is the wordplay.
'to be mishandled' indicates an anagram.
'claimed' with letters rearranged gives 'MEDICAL'.
(Other definitions for medical that I've seen before include "examination carried out by a doctor" , "Examination of physical health" , "Doctor's test" , "Declaim (anag) -- health check" , "Relating to the art of healing" .)
