Introduction: Numerous studies have explored variations in access to healthcare among racial and ethnic groups, revealing disparate challenges in insurance coverage and other healthcare services. Hyperosmolar Hyperglycemic State (HHS) or Hyperosmotic Hyperglycemic Nonketotic State (HHNK) represents a severe complication associated with type 2 diabetes mellitus. Objective of the study:To investigate if there are any racial disparities between white and black populations with the diagnosis of HHS, focusing on outcomes such as mortality rates, length of stay (LOS), hospital costs, and other outcomes. Methods: Retrospective data encompassing adult patients (age >18) with HHS between 2017 and 2020 were extracted from the National Inpatient Sample (NIS). Employing STATA as the data analysis tool, the International Classification of Diseases (ICD-10) was utilized to select disease and outcome codes. Multivariate regression analysis adjusted for relevant variables determining the adjusted odds ratio (aOR). Proportions were compared using the Fisher exact test, while continuous variables were assessed via the student t-test. The study's primary outcome was mortality, with secondary outcomes including LOS, total hospitalization costs, Acute Coronary Syndrome (ACS), septic shock, pulmonary edema, Acute Respiratory Failure (ARF), mechanical ventilation, Acute Respiratory Distress Syndrome (ARDS), Acute Kidney Injury (AKI), and Cerebrovascular Accident (CVA). Results: Among 181,720 HHS-diagnosed patients, 84,140 were white, and 58,645 were black. White patients exhibited a $2,741 higher total hospital expenses compared to their black counterparts. Rates of septic shock (aOR=0.78, 5.26% vs. 4.1%, p<0.001) and ARF (aOR=0.83%, 10.54 vs. 9%, p<0.001) were elevated in whites compared to blacks. Conversely, rates of AKI were higher in blacks (aOR=1.48, 58.29% vs. 50.58%, p<0.001) compared to whites. No statistically significant differences in mortality rates, mean LOS, ACS, pulmonary edema, mechanical ventilation, ARDS, and CVA were observed. Conclusion: Whites demonstrated increased rates of total hospital expenses, septic shock, and ARF compared to blacks, while blacks exhibited higher rates of AKI. No significant differences were observed in mortality rates, LOS, ACS, pulmonary edema, mechanical ventilation, ARDS, and CVA. Presentation: 6/2/2024
