O2‐04‐05: Disclosure of amyloid imaging results in cognitively normal individuals

(acute care, home care, physician visits), placement in long-term care and survival. New cases of physician-diagnosed dementia were also identified. Descriptive statistics and Cox proportional hazard models were used to compare individuals with and without dementia on these outcomes, and patient level demographic and functional predictors, including the role of coexisting chronic conditions, were examined. Results:There was a two-fold increase in the number of community-dwelling older adults with physiciandiagnosed dementia over six years (40,251 in 2007 to 74,450 in 2012). Compared to older adults without a dementia diagnosis, those with dementia were more likely to be 85 years and older (36.9% versus 9.9%), female (60.9% versus 54.8%) and a higher number of coexisting chronic conditions. At the end of six years 73.9% of individuals with dementia had visited an emergency department (versus 66.7% no dementia); 58.8% had been admitted to acute care (versus 45.0% no dementia) and 32.2% had applied for long-term care placement (versus 5.5% no dementia) (p-values >0.01). Over the six-year period 15.3% of individuals with dementia were placed in long-term care and 45.9% died. Conclusions: Our findings suggest that community-dwelling older adults with physician-diagnosed dementia make frequent contact with the Ontario health care system. Results highlight that community supports, such as home care, are priority areas for future investments.
