Vic mum wants answers over son's death

A Victorian mother whose newborn son died after staff at a hospital failed to diagnose his heart defect is still waiting for answers from public health officials nine years later.

Liam was born in 2006 at the Djerriwarrh Health Service in Bacchus Marsh, which is now under investigation after a later cluster of baby deaths caused by "multi-system" staff failures.

A review of 10 neo-natal deaths at Djerriwarrh between 2013 and 2014 found seven could have been avoided.

More families have since come forward about the deaths of their children at Djerriwarrh.

Liam's mother, Nichole Bink, was just 22 and Liam was her first baby.

He had a blue face and cold hands for 24 days before he died of a congenital heart defect.

After his death Ms Bink went to see a cardiologist at the Royal Children's Hospital to find out if she had a genetic problem.

That's when she learned Liam could have been saved by a 15-minute operation that had a 99 per cent success rate.

Ms Bink is still waiting for an explanation about her son's death.

"I haven't heard from anybody at all and it would be nice to hear from somebody, some sort of explanation, on why it happened," she told AAP.

"There's a lot of families out there who have gone through the exact same thing, and a lot of people are asking questions but nothing has been answered."

Health Minister Jill Hennessy has sacked the Djerriwarrh board, replacing it with an administrator.

Obstetrics expert Euan Wallace has been asked to expand his investigation to include neo-natal deaths and other serious cases at Djerriwarrh before 2013.

A former director of obstetrics and gynaecology at Djerriwarrh, Surinder Parhar, was investigated for 28 months after a complaint from a colleague over a baby's death in February 2013.

While he was being investigated, a number of babies died in potentially preventable circumstances.

Dr Parhar, who worked in Victoria for 30 years, had conditions placed on his ability to practise before he resigned in June.

It's understood he is no longer in Australia.

"If I had known what I know now, there's no way I would have gone to that hospital," Ms Bink says.

"For us to find out that they knew back then, that's pretty devastating."
