Key result
Dementia was a significant independent determinant of nontreatment with aspirin or warfarin at hospital discharge in older patients with acute ischemic stroke (OR 2.57; 95% CI 1.04-6.30).
Why the study?
Does a clinical diagnosis of dementia increase the likelihood of nontreatment with aspirin or warfarin for secondary stroke prevention in older patients?
Cohort (n=272)
No

Effect estimate: OR 2.57 (95% CI 1.04-6.30)
Older stroke patients with dementia are significantly less likely to be prescribed aspirin or warfarin for secondary prevention at hospital discharge.
No takes yet. Share an insight, caveat, or question.
Dementia may appropriately influence secondary prevention decisions post-stroke; leaves open whether this reflects optimal risk-benefit judgment or undertreatment.
Moroney et al. (1999) conducted a cohort in acute ischemic stroke (n=272). Dementia vs. No dementia was evaluated on Nontreatment with aspirin or warfarin at hospital discharge (OR 2.57, 95% CI 1.04-6.30). Dementia was a significant independent determinant of nontreatment with aspirin or warfarin at hospital discharge in older patients with acute ischemic stroke (OR 2.57; 95% CI 1.04-6.30).
