Doctor embraces home care (4)
I believe the answer is:
Here is my best explanation:
'care' is the definition.
'doctor embraces home' is the subsidiary indication.
'doctor' becomes 'md' ('MD' can be a synonym of 'doctor'**).
'embraces' means one lot of letters goes inside another.
'home' becomes 'in' ('he's home' can mean 'he's in').
'md' going around 'in' is 'mind'.
(Other definitions for mind that I've seen before include "Take care of; intellect", "Look after", "Seat of the faculty of reason", "Object to, intellect", "Intellect; object to", "Object to; take care of", "Intellect; care", "Take offence (at)", "remember" and "This can be made up".)
