Lind KE, et al. - Researchers performed a dynamic retrospective cohort study involving Australians with dementia in 68 residential aged care facilities to estimate the prevalence, duration, and time to initiation of anti-dementia medication (cholinesterase inhibitors or memantine). Further, they assessed resident and facility factors associated with use. This analysis consisted of 5,354 residents with dementia. Variation in anti-dementia medication use was observed in correlation to clinical and sociodemographic characteristics (3-points lower for single, 4-points lower for divorced relative to married residents, and 3-points higher for Australian-born). Lower anti-dementia medication use was observed in correlation to most comorbidities (myocardial infarction, cerebrovascular disease and heart failure 3-points lower, respiratory disease and diabetes 2-points lower). A complex relationship was observed between age and anti-dementia medication use that varied by sex and if medication was started before or after admission. Compared with females, males demonstrated earlier initiation of anti-dementia medication following admission. In all, anti-dementia medication use in Australian facilities was lower compared with other nations, and varied by clinical and sociodemographic factors.
