The Queensland government needs to better manage the state's health system with up to two-thirds of patients not being seen within recommended times at a popular hospital, the opposition says.
Opposition leader Deb Frecklington used recently released statistics about hospital waiting times to attack the government on Saturday, citing Logan Hospital as an example.
About 60 per cent of patients there aren't being seen within clinically-recommended times, she told reporters.
Ms Frecklington said with the health budget increasing 8.5 per cent, and the number of patients only up by five per cent, there was no reason the system can't be improved.
"Our hard-working doctors, nurses, they need support and our patients, the critically ill people who are fronting up to hospitals need help," she said.
"The solution is, Labor concentrating on managing the system better."
But the government says the opposition has distorted the statistics and claims Queensland is leading the country with targets for access to emergency treatment.
"A total of 99 per cent of the most critically-ill patients are seen within two minutes of arriving at our emergency departments and more than 75 per cent of all presentations were completed within four hours," acting health minister Shannon Fentiman said.
"(Other) patients have more complex conditions and it often takes more time to treat them, meaning patients with less urgent conditions sometimes have to wait longer to be seen."
Emergency department deal with 1.75 million patients between July 2016 and June 2017, an increase of 1.5 per cent for the same period the year before.
"Despite these demand challenges, a record number of people are receiving treatment within clinically-recommended timeframes in Queensland," Ms Fentiman said.
