Materials and Methods: Data are first-ever hospitalized strokes (2010-2014) in the Australian Stroke Clinical Registry from 39 hospitals linked to the national death registrations. Multilevel Poisson regression was used to estimate the women:men mortality rate ratio (MRR), with adjustment for sociodemographics, stroke severity, and processes of care (stroke unit care, intravenous thrombolysis, antihypertensive agent[s], and discharge care plan).
Results: Among 14,118 events (46% females), women were 7 years older and had greater baseline severity compared to men (29% vs. 37%; p < 0.001), but there were no differences in the four processes of care available across hospitals. In the whole cohort, 1-year mortality was greater in women than men (MRRunadjusted 1.44, 95% confidence interval [CI] 1.34-1.54). However, there were no differences after adjusting for age and stroke severity (MRRadjusted 1.03, 95% CI 0.95-1.10). In analyses of additional processes from Queensland hospitals (n = 5224), women were less often administered aspirin ≤48 hours (61% vs. men 69%, p < 0.015). In Queensland hospitals, there were no statistically significant sex differences in 1-year mortality after adjusting for age, stroke severity, and early administration of aspirin.
Conclusion: Greater mortality in women can be explained by differences in age and stroke severity. This highlights the importance of better management of risk factors in the elderly and, potentially, the need for greater access to early aspirin for women with stroke.
