Tess disturbed about hospital room attendants (8)
I believe the answer is:
stewards
'attendants' is the definition.
(steward is a kind of attendant)
'tess disturbed about hospital room' is the wordplay.
'disturbed' indicates anagramming the letters (the order of letters is disturbed).
'about' is an insertion indicator.
'hospital room' becomes 'ward' (I've seen this before).
'tess' is an anagram of 'stes'.
'stes' enclosing 'ward' is 'STEWARDS'.
(Other definitions for stewards that I've seen before include "They look after passengers on aircraft or ship" , "Custodians" , "Attendants, on aircraft say" , "They look after passengers on aircraft and ships" , "waiters" .)
