Social deprivation and stroke severity on admission : a French cohort study in Burgundy and the West Indies - Guyana region

Abstract : BACKGROUND AND PURPOSE: Although there is growing and convincing evidence that socially deprived patients are at higher risk of stroke and worse outcomes, it remains controversial whether or not they suffer more severe stroke. This study aimed to evaluate the influence of social deprivation on initial clinical severity in patients with stroke. METHODS: A total of 1536 consecutive patients with an acute first-ever stroke (both ischaemic stroke and intracerebral hemorrhage) were prospectively enrolled from six French study centers. Stroke severity on admission was measured by the National Institutes of Health Stroke Scale score. Social deprivation was assessed at the individual level by the Evaluation de la Précarité et des Inégalités de santé dans les Centres d'Examen de Santé (EPICES) score, a validated multidimensional questionnaire, and several additional single socioeconomic indicators. Polytomous logistic regression analyses were performed to evaluate the association between social deprivation and stroke severity. RESULTS: In univariate analysis, the EPICES score (P = 0.039) and level of education (P = 0.018) were the only two socioeconomic variables associated with stroke severity. Multivariate analysis of the association between EPICES and National Institutes of Health Stroke Scale scores showed that more deprived patients presented a significantly higher risk of both mild and moderate/severe stroke (odds ratio for mild versus minor stroke, 1.39; 95% confidence interval, 1.06-1.84; odds ratio for moderate/severe versus minor stroke, 1.44; 95% confidence interval, 1.09-1.92). A non-significant trend towards a higher risk of both mild and moderate/severe stroke in less educated patients was observed. CONCLUSIONS: Social deprivation was associated with a more severe clinical presentation in patients with stroke. These findings may contribute to the worse outcome after stroke in deprived patients, and underline the need for strategies to reduce social inequalities for stroke. © 2017 EAN.
