OBJECTIVES/SPECIFIC AIMS: Projected to soon become the most prevalent cause of End-Stage Liver Disease, the frequency of Non-Alcoholic Fatty Liver Disease (NAFLD) has been rising in the US community. However, studies on NAFLD among inpatients are lacking. Aims: To report the 1) prevalence and trends, 2) outcomes of NAFLD associated hospitalizations in the US. METHODS/STUDY POPULATION: NAFLD cases were identified in the National Inpatient Sample (2007-2014) with ICD-9-CM codes, and the prevalence and trends over the 8-year period were calculated among different demographic groups. After excluding secondary causes of hepatic fat accumulation from the NAFLD cohorts (n = 210,660), the impact of sex, race, and region on outcomes (mortality, discharge disposition, length of stay [LOS] and cost) of NAFLD was computed with generalized estimating equations (SAS 9.4). RESULTS/ANTICIPATED RESULTS: Admissions with NAFLD tripled from 2007-2014 at an average rate of 79/100,000 hospitalizations/year (p-value < 0.0001), with a larger rate of increase among males vs. females (83/100,000 vs. 75/100,000), Hispanics vs. Whites vs. Blacks (107/100,000 vs. 80/100,000 vs. 48/100,000), and governmental-/un-insured patients vs. privately-insured (94/100,000 vs. 74/100,000). Males had higher mortality, LOS and cost than females. Blacks had longer LOS and poorer discharge destination than Whites; while Hispanics and Asians incurred higher cost than Whites. Uninsured patients had higher mortality, longer LOS and poorer discharge disposition than the privately-insured. DISCUSSION/SIGNIFICANCE OF IMPACT: Hospitalizations with NAFLD is rapidly increasing in the US, with a disproportionately higher burden among certain demographic groups. Measures are required to arrest this ominous trend and to eliminate the disparities in outcome among patients hospitalized with NAFLD.
