Ratko Dujela, 79, was last seen at Sunshine Hospital about 4pm Friday, where he left with a cannula still in his arm after being admitted on Thursday.
“I literally just left work dropped everything and went to my mum’s,” step daughter Jacinta Neralic said.
His family were the ones to report him missing and police are appealing for public assistance to help locate the missing St Albans man who lives with dementia and poor eyesight.
They said his family is very worried about his welfare and have searched everywhere possible, concerned he is about to spend a third night on his own.
Ms Neralic said the family was particularly worried given the amount of time he has been missing, the heat during the day and cooler temperatures at night.
“Having dementia he doesn’t know that he’s lost,” she said.
“He hasn’t eaten, he hasn’t slept … he hasn’t had anything to drink.
“We’ve exhausted all avenues, to be honest.”
Ms Neralic said friends and work colleagues had been supportive in their search of her stepfather.
Mr Dujela’s partner of 16 years, Helen Guenzi, said everybody loved the 79-year-old and she just wanted him home.
“My God … what’s happened … I hope he’s alive,” Ms Guenzi said.
“I do everything for him … I hope he comes back.”
This is not the first time the grandfather has gone missing.
In October, social media helped track him down when he disappeared, but the family feels they are running out of options this time.
“It’s like trying to find a needle in a haystack … we’ve spent almost three days driving around looking for him … where do you look? We don’t know,” Ms Neralic said.
Police are patrolling the streets trying to find the elderly man.
“We’re currently conducting ongoing searches around the Brimbank area to try and locate Ratko from searching parklands, pokies venues and shopping centres,” Sergeant Shane Wallace said.
Mr Dujela is described as being 198cm tall with a solid build and grey hair.
He was last seen wearing a striped tan coloured top and blue jeans.
