IntroductionRace and socioeconomic status (SES) is interconnected. There is scarce data analyzing trends of atrial fibrillation (AF) in-hospital mortality in black and non-black adults based on SES. MethodsWe queried the National Inpatient Sample database from January 2004 to December 2018 to identify patients admitted with AF. We used ICD-9-CM and ICD-10-CM diagnosis codes to identify all patients who were 18 years of age or older and hospitalized with a primary discharge diagnosis of Atrial Fibrillation. Our cohort was further categorized by race, into black and non-black groups, and socioeconomic status (SES) using median household income (MHI) as a surrogate, into low SES (MHI 0-50) and high SES (MHI 51-100). We excluded all patients with incomplete data on age, gender, race, MHI and in-hospital mortality status. Also, in order to reduce the possibility of data duplication, the patients with an indicator for transfer to another acute-care facility were excluded. Cochran-Armitage Test was utilized to estimate temporal trends. ResultsBlack and non-black adults have had improvement of in-hospital mortality, although black adults still have higher trends as compared to non-black counterparts (p
