There are concerns a lack of data on regional hospital demand is obscuring the strain the system is under, with reports an SA emergency department had twice as many patients as it did treatment spaces.
The SA Salaried Medical Officers Association (SASMOA), which represents doctors working in hospitals, said a code white should have been activated last Wednesday at the Mount Gambier hospital.
A code white is called when a hospital's emergency department reaches 125 per cent capacity.
SASMOA chief industrial officer Bernadette Mulholland said members at the hospital claimed they had 12 treatment spaces and 30 patients.
Ms Mulholland said that surge in demand would normally trigger an "escalation plan" that would help to decompress the ED and take pressure off the staff.
"When there's insufficient spaces it makes it difficult to see those acutely unwell patients in the emergency department," she said.
"It also increases the distress of not only the clinicians, but also the patients."

Data needed to solve problems
A publicly available dashboard tracks the status of Adelaide emergency departments, but does not include regional hospitals.
Ms Mulholland said that made it difficult to know whether incidents of overcapacity were anomalies or patterns.
"What would be useful to understand better the pressure on our rural hospitals, particularly our bigger rural hospitals like Mount Gambier, Gawler and Mount Barker, is to have those added to the dashboard," she said.
"It provides a better understanding for people in that rural community the type of pressure that is on the emergency department.
"That would give us some really good data to work with the [health] department and the government to ensure there is sufficient capacity in these hospitals."

SA Shadow Health Minister Jack Batty said he had heard anecdotal reports from patients about the pressure the health system is under.
"We know our doctors and nurses in the regions are doing an extraordinary job, but they're being stretched to breaking point by a hospital system that isn't coping," he said.
"If we can't properly identify the extent of the problem, how on earth are we going to plan for the solutions?"

Statewide health strain
Health Minister Blair Boyer said presentations to EDs across the state had increased in recent weeks.
He said the number of patients waiting to be transferred from hospital beds to aged care facilities increased pressure on hospitals.
"You add on top of that we've had a spike in flu cases … it's those things that are driving this really high pressure we're seeing on our hospitals," he said.
"We are [also] seeing an increase in the people presenting who need care."

Government data showed ED presentations at Mount Gambier hospital had increased each year since the 2020-21 financial year, including an increase from 27,351 in 2024-25 to 28,621 in the last financial year.
Mr Boyer said he would look at providing regional hospital data on the ED dashboard, but he would "have to be convinced it would provide value and change".
Limestone Coast Local Health Network acting CEO Kylie Williams said the the hospital was dealing with a "continued rise" in presentations.
She added that the hospital had increased clinical staff from 303 full-time equivalent positions to 354 in 2026.
