Out-of-hospital Cardiac Arrest (OHCA) is the abrupt cessation of cardiac function outside of a hospital setting. With limited research into the presence of racial disparities among outcomes of OHCA patients, this systematic review and meta-analysis was conducted. PubMed, Cochrane, and Scopus were searched from inception to March 2023. This analysis includes a total of 53,507 black patients, and 185,173 white patients, resulting in the pooling of 238,680 patients in this meta-analysis. It was observed that the black population was associated with significantly worsened survival to hospital discharge (OR: 0.81; 95% CI: 0.68, 0.96, P = 0.01), return of spontaneous circulation (OR: 0.79; 95% CI: 0.69, 0.89, P = 0.0002), and neurological outcomes (OR: 0.80; 95% CI: 0.68, 0.93; P = 0.003) when compared to their white counterparts. However, there were no differences found with respect to mortality. To the best of our knowledge, this is the most comprehensive meta-analysis assessing racial disparities in OHCA outcomes that have never been explored before. Increased awareness programs, and greater racial inclusivity in the field of cardiovascular medicine is encouraged. Further studies are needed in order to arrive at a robust conclusion.
