The Health Quality and Complaints Commission (HQCC) annual report 2007-08, released on Tuesday, shows the commission managed 2,675 health complaints in the period, closing 42 per cent of cases within 30 days.
The independent statutory organisation - established in 2006 to manage health complaints and improve the quality and safety of the state's health care - completed 24 investigations in the period.
At June 30, 2008, 94 investigations were still active.
In the report, Commissioner Michael Ward identifies information exchange between health services as a key issue for improvement.
"Although serious individual clinician performance failures are fortunately uncommon, they may often be identifiable from information held but not shared by hospitals, medical boards and specialist medical colleges," Prof Ward writes.
"There may well be legal and other barriers that currently prevent these agencies from exchanging this information, but as long as these barriers remain and the key information is not collated, analysed and used appropriately, avoidable problems are likely to recur."
Health Minister Stephen Robertson said the commission would help drive the government's health reform agenda.
"The HQCC has wide-ranging powers to monitor the quality of health services provided to Queenslanders," Robertson said in a statement.
"These include recommending action to improve the quality of health care services, resolving individual health complaints and promoting health rights."
