The Brisbane Mater Mothers' Public Hospital is investigating the death of a woman who died just days after being sent home after giving birth.
It's understood she was discharged from hospital last month and had suffered a suspected blood clot after having a caesarean delivery.
Mater Health Chief Executive Officer Sean Hubbard confirmed on Thursday the woman's death was being investigated but gave no further details.
"As would be the case with any unexpected clinical outcome, Mater will conduct a thorough and detailed review into the care and treatment provided while she was at Mater," he said in a statement.
"The case has also been referred to the coroner."
Queensland Health Minister Steven Miles did not comment directly on the woman's case but did say Queensland public maternity services are among the safest in the world.
"The Palaszczuk government has focused on increasing resources and staff, making sure that Queensland mums and bubs, and their families have the very best pre and post-natal care," Mr Miles said in a statement.
Despite this, any maternal death was a tragedy, he said.
