Hands-on treatment suits a hospital casualty? (7)

I believe the answer is:

shiatsu

I'm a little stuck... Click here to teach me more about this clue!

'hospital casualty?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.

'hands-on treatment suits a' is the wordplay.
'hands' becomes 'h' (this could be a standard abbreviation which I don't know about).
'on' indicates putting letters inside.
'treatment' is an anagram indicator (letters treated or processed differently).
'suits'+'a'='suitsa'
'suitsa' anagrammed gives 'siatsu'.
'h' placed within 'siatsu' is 'SHIATSU'.

(Other definitions for shiatsu that I've seen before include "Japanese healing therapy using massage with the fingers" , "form of massage" , "Treatment involving finger pressure at specific points" , "Form of treatment that entails pressure with the fingers on specific points on the body" , "form of Japanese therapy" .)
