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%, p0.01) and mechanical ventilation (aOR =1.24, 7.04% vs. 5.79%, p0.01) compared to the weekday admission. There was no difference in the outcomes of the two groups in the mortality rate, mean LOS, total hospital charges, ACS, septic shock, pulmonary edema, AKI, CVA, and ARDS. In weekend admission, there was an increase in trends of LOS and total hospitalization charges, but there were no significant outcomes in the mortality rates over the years. In weekday admission, there was an increase in mortality rate trends, LOS, and total hospitalization charges. Conclusion: There was an increase in ARF and mechanical ventilation rates on weekends compared to weekday admission. When the two groups were compared, there were no significant outcomes in mortality rate, LOS, hospital charges, and other hospital outcomes. In both weekend and weekday admissions, there was an increase in trends of LOS and total hospitalization charges; however, only admissions during the weekday showed a significant increase in mortality rate trends.
