7313 Impact of Day of Admission on Hyperosmolar Hyperglycemic State Outcomes- a National Inpatient Sample Study

Abstract Disclosure: B. Neupane: None. S. Karki: None. A. Bhandari: None. K. Rajamani: None. Introduction: Hospital mortality and results are significantly influenced by the day of admission (weekend vs. weekday). Studies have shown there is an increase in rates of adjusted hospital mortality in various diseases. Hyperosmolar hyperglycemic state (HHS), or Hyperosmotic hyperglycemic nonketotic state (HHNK), is a serious complication associated with type 2 diabetes mellitus. There have been limited studies on how the day of admission impacts outcomes in HHS. Objective:To investigate if there are differences in weekend vs. weekday admission with the diagnosis of HHS on hospital outcomes. Methods: Retrospective data on adult patients (age >18) with a primary diagnosis of HHS was taken between 2017 and 2020 using the National Inpatient Sample (NIS). The data analysis tool utilized was STATA. Diseases and outcome codes were selected using the International Classification of Diseases (ICD-10). Multivariate regression analysis was used to adjust for potential variables and determine the adjusted odds ratio (aOR). The Fisher exact test was used to compare proportions, while the student t-test was used to compare continuous variables. The study's primary outcome was mortality; additional secondary outcomes included length of stay (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 accidents (CVA). Between 2017 and 2020, the mortality rates, LOS, and total hospitalization charges of weekend and weekday admissions were analyzed. Results:181,720 patients were diagnosed with HHS; 46,100(25.36%) were admitted on the weekend. Weekend admission had increased rates of ARF (aOR =1.2, 11.15% vs. 9.57%, p
