Abstract

Objectives To explore the impact of dementia on the trends in fall-related fracture and non-fracture injuries for older people. Methods Individuals aged ≥65 years who were admitted to a NSW hospital for at least an over-night stay for a fall-related injury from 2003 to 2012 were identified. Age-standardised hospitalisation rates, length of stay, access to in-hospital rehabilitation, 30-day and 1-year mortality were examined. Annual percentage change (PAC) over time was calculated using negative binomial regression. Results Of the 228,628 fall-related injury hospitalisations, 20.6% were for people with dementia. People with dementia were more likely to be admitted with a hip fracture, and less likely to be admitted with a fracture of the forearm/wrist, and received less in-hospital rehabilitation than people without dementia. Fall-related hip-fracture rates for people with dementia decreased by 4.2% (95%CI −5.6 to −2.7, p < 0.001) per annum; there was no change over time for people without dementia (PAC-0.2%; 95%CI −0.8 to 0.5, p = 0.643). Rates for other fractures decreased by 1.2% (95%CI −1.9 to −0.5, p < 0.001) per annum in people with dementia, while rates increased by 2.2% (95%CI 1.9–2.5, p < 0.001) for people without dementia. By contrast, non-fracture injuries including traumatic brain injury increased significantly for both people with and without dementia. Conclusion Rates of fall-related fracture and non-fracture hospitalisations for people with dementia remain higher than for those without dementia. However, fall-related fracture hospitalisation rates have decreased for people with dementia, while there has not been a corresponding decrease in people without dementia.
