One may write a column about hospital worker (8)
I believe the answer is:
reporter
'one may write a column' is the definition.
(I've seen this before)
'about hospital worker' is the wordplay.
'about' becomes 're' (regarding).
'hospital worker' becomes 'porter' (I've seen this before).
're'+'porter'='REPORTER'
(Other definitions for reporter that I've seen before include "Newsman" , "He gives details" , "Newspaperman" , "One gives us the news" , "One may get a story" .)
