The Australian Medical Association says the Government should be boosting hospital bed numbers instead of patients having to be treated in hospital corridors.

It is not the only organisation critical of the practice with the WA nurses union labelling it degrading and dangerous.

The AMA WA president Richard Choong says patients should not be treated in hallways.

"Overcrowding has reached such a point that we've actually institutionalised it, we've made it normal by installing these facilities," he said.

Dr Choong was referring to hospitals installing additional power points in corridors to be able to treat patients in ward hallways.

The Australian Nursing Federation's Mark Olson says he has received emails from nurses complaining of patients being routinely treated in makeshift bays in corridors, marked with gaffer tape on the floor.

"The government has normalised a practice that degrades and humiliates the patients," he said.

"The government will have you believe these are emergency measures.

"I'm sorry, these are measures which have been deliberately put in place because I'm sure if we didn't have a copy of that policy, then the government would deny that it exists."

Mr Olson says the practice is dangerous.

"This is how they have moved the problem from the emergency departments and filtered it up through the hospital," he said.

"So, we have patients in corridors where there is no suction, there is no emergency equipment, where there is no electricity, and often they are in corridors because they waiting for a room."

There have been reports of Perth hospitals being forced to install additional power points in ward corridors to treat patients in hallways.

Earlier, the Premier Colin Barnett said patient care has not been compromised.

Mr Barnett says while it is not ideal, WA patients are still receiving unrivalled care.

"That's clearly undesirable but can I stress, and even from personal experience in my family, where that's happened there's been no lesser level of patient care," he said.

The Opposition's Roger Cook says services are clearly being affected.

"This is another sign the health system under the Barnett government is being mismanaged," he said.

It comes as new figures reveal ambulances were ramped outside Perth hospitals for almost 1,600 hours last month, double the number recorded in June last year.

Mr Barnett says concerns of overcrowding need to be kept "in perspective."

He says growing demand on health services will be eased when new hospital services are rolled out.

"We need more capacity but you can't create a hospital overnight," he said.

"And, if I can say so, this government is building the greatest rebuild of new hospitals in the state's history and they will start to come online next year."
