This report examines the experiences of the 252,700 people aged 50 and over who stayed for at least one night in a New South Wales public hospital in 2006-07. Slightly more than 8% of patients (20,800 people) were identified as having dementia. Even allowing for age and sex differences, people with dementia had much higher hospitalisation rates than those without dementia: 26% compared with 12%. They also tended to stay longer in hospital and were more likely to enter or return to residential care on discharge from hospital, or to die in hospital.
