An inn set about establishing a health scheme (4)

I believe the answer is:

bupa

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

'a health scheme' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'an inn set about' is the wordplay.
'an' becomes 'a'.
'inn' becomes 'pub' (both can mean a drinking establishment).
'set about' shows that the letters should be reversed in order.
'a'+'pub'='apub'
'apub' written backwards gives 'BUPA'.

'establishing' acts as a link.

Can you help me to learn more?
