Leading intensivist rushed back with nurses behind (2,7)

Ross

I believe the answer is:

in arrears

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

'behind' is the definition.
(I've seen this before)

'leading intensivist rushed back with nurses' is the wordplay.
I cannot really understand how this works, but
'back' could be 'rear' (synonyms) and 'rear' is present in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for in arrears that I've seen before include "Owing" , "Behind with payments" , "Behindhand (with rent)" , "Overdue" , "Rare rains beyond the due time" .)

I've seen this clue in The Hindu.
