An elderly patient was left in blood-soaked, vomit-stained clothing for two days at St Vincent's Hospital after being admitted last week, according to a family member, who today labelled his treatment "disgusting".

Ron Kenyon, 79, was taken to St Vincent's with head injuries after falling down steps in Geelong on Thursday last week.

His stepdaughter, Lisa Llewellyn, said Mr Kenyon was rushed from Geelong Hospital after suffering "a brain bleed and also an external bleed and a number of other injuries" from the fall.

But when Ms Llewellyn and her brother, who both live in Sydney, visited Mr Kenyon on Saturday they were shocked to find him still dressed in filthy clothing.
