ABSTRACT
In an Australian nursing home population, associations between cognitive function and 12-month hospitalizations and costs were examined. Participants with dementia had 57% fewer hospitalizations compared to those without dementia, with 41% lower mean hospitalization costs; poorer cognition scores were also associated with fewer hospitalizations. The cost per admission for those with dementia was 33% greater due to longer hospital stays (5.5 days versus 3.1 days for no dementia, p = .05). People with dementia were most frequently hospitalized for fractures. These findings have policy implications for increasing investment in accurate and timely diagnosis of dementia and fall and fracture prevention strategies to further reduce associated hospitalization costs.

Key Points
People living in nursing homes are at high risk of hospitalization.
Australians in care with dementia had fewer hospitalizations than those without.
Hospital cost and length of stay was greater for people in care with dementia.
Fractures were the most common reason for hospitalization for those with dementia.
Falls prevention programs could reduce hospitalizations and costs of dementia care.

Statement of ethics
Human research ethics approval was obtained from the Flinders University Social and Behavioural ethics committee (references, 6594, 6732, 6753) and by federal and state custodians of hospital data: the Department of Veterans’ Affairs Human Research Ethics Committee (reference, E015/014), the SA Department for Health and Ageing Human Research Ethics Committee (reference, SSA/16/SAH/29), the Department of Health WA Human Research Ethics Committee (reference, 2015/59), the Queensland Department of Health (reference, RD006096), and the NSW Population and Health Services Research Ethics Committee (reference, HREC/15/CIHS/35). Self-consent by patients to participation was obtained when possible; for participants with more severe cognitive impairment, proxy consent for participation was provided (usually by a close family member).
