New data has uncovered more than 60% of patients at a major Queensland hospital are not being seen within clinically recommended times.

Government data has shown Logan Hospital was amongst the worst in the state, where 61% of patients were not being seen within the recommended time frame.

Opposition leader, Deb Frecklington, said with the health budget increasing by 8.5%, and the number of patients only up by 5%, there was no reason the system couldn't be improved.
