Background Posterior circulation strokes (PCS) make up 20% of all strokes, yet there is poor understanding of what factors contribute to poor clinical outcomes. We investigated clinical and demographic characteristics associated with poor clinical outcomes in PCS using a population-based biracial cohort.

Objective We aim to better understand what clinical and demographic characteristics are associated with poor clinical outcomes in posterior circulation strokes.

Design/Methods Greater Cincinnati Northern Kentucky Stroke Study (GSNKSS) 2010 and 2015 data were utilized to identify 1842 patients who were >20 years old with MRI-proven PCS. Eligible patients were then stratified based on functional outcomes (modified Rankin Scale<3 vs >/= 3, with >= 3 considered poor) according to demographics, stroke risk factors, tPA treatment, stroke location, and stroke mechanism were summarized. A multivariable logistic model was then used to identify the predictors for poor functional outcomes.

Results Age, female gender, higher NIHSS, higher baseline mRS, hypertension, atrial fibrillation, diabetes mellitus, temporal, thalamic, cerebellar, and brainstem location, and small-vessel and cardioembolic mechanism were associated with poor clinical outcomes (p-value <0.01). After multivariable analysis, higher NIHSS, higher baseline mRS, hypertension, temporal, thalamic, cerebellar, and brainstem location, and cardioembolic mechanism remained associated with poor outcomes (p-value <0.01, OR 95% CI >1.00).

Conclusions Understanding these factors associated with poor prognosis after posterior circulation stroke will allow for better prognostication and family counseling.
