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

'these medical facilities' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'antria is a doctor' is the wordplay.
'doctor' indicates anagramming the letters.
'antria'+'is'+'a'='antriaisa'
'antriaisa' is an anagram of 'SANITARIA'.

'in' is the link.
