A measure of home treatment (5)

I believe the answer is:

metre

'a measure' is the definition.
(metre is a kind of measure)

'of home treatment' is the wordplay.
'of' says the answer is hidden in the clue.
'METRE' is hidden in the letters of 'home treatment'.

(Other definitions for metre that I've seen before include "Alignment of feet determines such" , "Poetic rhythm" , "39.37 inches" , "determined by scanning" , "Yard is smaller than this" .)

I've seen this clue in the Evening Standard.
