Candidates for transplant dopy coming round in London hospital (4,5)

'candidates for transplant' is the definition.
(body parts can be transplanted)

'dopy coming round in london hospital' is the wordplay.
I cannot quite see how this works, but
an anagram of 'dopy' is 'odyp' which is present in the answer.
'hospital' could be 'barts' (short for St Bartholomew's Hospital) and 'barts' is present in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
