Get lost in poorly-ventilated institute of education (5,3)

I believe the answer is:

stuff you

'get lost' is the definition.

'poorly-ventilated institute of education' is the wordplay.
'poorly-ventilated' becomes 'stuffy'.
'institute of education' becomes 'ou' (abbreviation for Open University).
'stuffy'+'ou'='STUFF YOU'

'in' acts as a link.

I've seen this clue in The Independent.
