A former medical board investigator says a report recommending criminal charges be considered against six Queensland doctors should go further.

The report is the result of an investigation lead by former Fitzgerald inquiry prosecutor and Brisbane barrister Jeff Hunter.

Mr Hunter was hired by the State Government following whistleblower complaints last year, and asked to determine if charges should be laid against doctors who were disciplined over the deaths or harming of their patients.

The ABC has obtained a copy of the report, which recommends six doctors be referred to police for possible criminal charges involving 23 cases.

But whistleblower and former investigator for the Medical Board of Queensland, Jo Barber, says that figure should be closer to 100.

"I am very surprised that they have only chosen to look at six doctors," she said.

"I worked at the medical board and I am familiar with the files there and there are many, many more than six doctors that should be investigated for criminal offences.

"Mr Hunter refers to 89 that he looked at and that's a closer figure in my mind, much closer to 100, that should be considered for criminal charges at the medical board at least.

"My view is that these six are the patsies - let's give them a couple of scalps, let's keep the public happy and then we can just leave the system alone."

Legislative change?

Health Minister Lawrence Springborg says one doctor is linked to 11 of the cases.

He says some incidents involve surgery being done without relevant symptoms, while others involve failed cosmetic and surgical procedures.

Mr Springborg says Queensland needs an effective and accountable health complaints process.

He says the findings will help shape legislative change to alter the way allegations of medical malpractice are handled in the future.

The minister says he is happy to heed the advice of the report author, Mr Hunter.

"In his very considered and studious view, there would only be any hope of being able to sustain charges against six particular individuals and I think we need to respect that," Mr Springborg said.

"This has been an enormously thorough investigation and review by a very, very well-respected Queensland senior lawyer."

The Queensland branch of the Australian Medical Association (AMA) says it is preparing a detailed response to ensure the matters can be addressed openly, transparently and efficiently in the future.

The AMA says all Queenslanders deserve the highest standard of medical care and accountability, and the majority of doctors working in the state are highly skilled and dedicated to improving their patients' health and wellbeing.
