Queensland's corruption watchdog and health ombudsman have been asked to investigate a former government psychiatrist after he wrote a book about killers he once examined.
Donald Grant has defended his decision to write 'Killer Instinct', a new book that draws on contact he had with 10 killers when he was working for Queensland Health.
Queensland Health said it acted on a request from Health Minister Steven Miles to refer the matter to the health ombudsman, and to the Crime and Corruption Commission to consider "any issues of potential corrupt conduct".
"We can't underestimate how serious an issue this appears to be," a Queensland Health spokesperson said in a statement.
"On its surface it looks like a betrayal of patients, victims and their families and the clinicians duty to do the right thing professionally."
Sonia Anderson, mother of slain Queensland woman Bianca Girven, confronted Dr Grant at his book launch earlier in the week, saying the book contained previously undisclosed details about her daughter's final moments of life.
Dr Grant, who stopped working for Queensland Health in 2013, has said grieving families deserve "insight into why their loved ones were killed".
In a statement released by his publisher, he denied breaching doctor-patient confidentiality.
He said the interviews he conducted weren't for treatment, but rather for assessments that were provided to the courts.
