Western Australia's health unions say tensions arising from the death of Aishwarya Aswath will not be tempered until the government pledges to fix systemic problems.
The Australian Medical Association (AMA) has made good on its threat to refer two high-ranking health officials to the Australian Health Practitioner Regulation Agency (AHPRA) over the handling of the Easter Saturday tragedy.
AMA State President Andrew Miller said Perth Children's Hospital boss Aresh Anwar and WA health department director general David Russell-Weisz should face the same scrutiny from the medical watchdog as junior staff.
"We don't shy away that there could have been problems at all levels," Dr Miller told reporters on Sunday.
"But what we don't want to see is the powerless junior staff being the only ones who are looked at closely, particularly by their professional regulator."
A report by WA's Child and Adolescent Health Service found PCH emergency department staff missed a "cascade" of opportunities to escalate seven-year-old Aishwarya's care as she succumbed to a fatal infection.
WA Premier Mark McGowan's government has insisted the hospital was adequately staffed but the unions reject that claim.
They say the AHPRA investigation should only go ahead once a planned coronial inquest and an independent review into PCH's emergency department are finalised.
Mr McGowan on Sunday reiterated his call for warring parties to de-escalate the conflict and allow Aishwarya's parents to properly grieve.
"The anger needs to be taken out of this," he said.
"We're dealing with a little girl's family, and she died. I don't think they need this."
But the AMA and Australian Nurses Federation are not backing down, hatching plans for staff to rally outside PCH on Tuesday.
ANF State Secretary Mark Olson said he had a mandate for the action, with a survey showing 96 per cent of its members support walking off the job.
"We want the minister to acknowledge there are serious problems, systemic problems, that require everybody working together," he said.
"If it helps, let's not point the finger of blame. Let's just all work together to get the system fixed."
Mr Olson also called for Health Minister Roger Cook to drop his other portfolios and concentrate on health.
The AMA's Dr Miller said he had not spoken to Mr Cook since the March state election and tensions would remain high as long as the problem remained unresolved.
"I'm not going to get calm, I'm not going to be quiet," he said.
"We're not going to turn the temperature down until they fix the emergency departments, and they're not going to fix them until they acknowledge the problems in the system that they've been in control of for four years now."
