Institutional review board statement: The National Inpatient Sample database contains numerous safeguards to protect patient privacy. It also lacks patient- and hospital-specific identifiers. Therefore, our study was exempt from Institutional Review Board (IRB) evaluation as per guidelines put forth by our institutional IRB for analysis of HCUP databases.
Informed consent statement: The data for this study was collected from the National Inpatient Sample (NIS) database. As the NIS database lacks patient-specific and hospital-specific identifiers, this study did not require informed consent.
Conflict-of-interest statement: All the authors report no relevant conflicts of interest for this article.
Data sharing statement: The National Inpatient Sample is a publicly available database that can be accessed at Due to the availability of a large sample size within the NIS database, it is an ideal choice for the estimation of national trends and clinical outcomes.

Core Tip

Core Tip: Due to dietary and lifestyle changes, the prevalence of non-alcoholic fatty liver disease (NAFLD) is on the rise worldwide. Peptic ulcer disease (PUD) is commonly seen in patients with liver cirrhosis. However, data on PUD in NAFLD hospitalizations is currently lacking. In this study, we noted an increase in inpatient mortality for NAFLD hospitalizations with PUD in the United States. The rates of Helicobacter pylori infection and upper endoscopy for NAFLD hospitalizations with PUD were on the decline. Despite a higher comorbidity burden, inpatient mortality, mean length of stay, and mean total healthcare cost were lower for NAFLD hospitalizations with PUD compared to the non-NAFLD cohort.
