Delirium is a serious medical condition where people experience sudden changes in their thinking, attention and memory, causing them to become confused, agitated or drowsy.

Usually lasting from a few days to weeks, it can lead to serious complications such as falls, pressure injuries, longer hospital admissions and sometimes death.

We know the best treatment for delirium is prevention – around 30-40 per cent of delirium cases that occur in hospital are preventable. However, delirium is not well detected by health professionals and is often misdiagnosed for dementia or depression.

We partnered with the Institute for Healthcare Improvement (IHI) and 21 health services to deliver this collaborative, using the IHI’s proven Model for improvement.
