Racial Disparities in Acute Stroke

Sponsor: Fondazione Policlinico Universitario Agostino Gemelli IRCCS

Summary

Ischemic stroke is one of the leading causes of mortality and disability worldwide. Although the prevalence of stroke is high globally, not all ethnic and racial groups are affected in the same way, leading to the classification of stroke as an inequitable disease. First of all, ethnic and racial background influences the pathogenesis of stroke, as numerous risk factors-both modifiable and non-modifiable-are more prevalent in Black and Hispanic populations compared to Asian ones. As a direct consequence, the incidence of stroke is higher in Black and Hispanic individuals than in White individuals. Unfortunately, despite this, access to revascularization treatments is not always guaranteed for ethnic and racial minorities, although in recent years, this inequality in access to care appears to be decreasing. Moreover, stroke prognosis also seems to differ based on race/ethnicity, with mortality being higher among Black individuals compared to White individuals, although this trend tends to decrease with advancing age. On the other hand, although cerebral hemorrhage is more prevalent in Black and Asian populations than in White populations, it tends to have a better prognosis in these minority groups. It must be considered, however, that the vast majority of studies on this topic have been conducted in the United States, where the ethnic and racial composition of the population is very different from that of Italy and Europe. In these latter contexts, studies investigating the impact of race and/or ethnicity on the clinical characteristics, management, and prognosis of ischemic stroke are lacking. Furthermore, differences in healthcare system organization may play a significant role in limiting access to timely and appropriate medical care for acute stroke based on race and/or ethnicity. Italy is a country where, similarly to other European nations, the last few decades have seen a significant increase in immigration rates, particularly from Eastern Europe. Today, foreigners account for approximately 9% of the total population. Nevertheless, in Italy, systemic racism toward ethnic and racial minorities remains a significant issue, as evidenced by large disparities in educational attainment, socioeconomic status, and housing conditions between Italian citizens and foreign residents. Although the universal national healthcare system in Italy should ensure equal access to care and emergency treatment for all, regardless of ethnic and racial background, there are no studies investigating this topic. A recent scoping review highlighted how individual racism plays a primary role in generating health inequalities, whereas there is very limited evidence focused on the analysis of structural and institutional racism in the Italian and European context. As a consequence, this study aims to prospectively investigate the presence and the extent of racial and ethnic disparities in access to stroke care and treatment across several Italian comprehensive stroke centers.
