Outcomes of Upper Gastrointestinal Bleeding in Hospitalized Patients With Generalized Anxiety Disorder

Background Upper gastrointestinal bleeding (UGIB) has a high morbidity and mortality. Social deprivation is a risk factor for UGIB and is associated with anxiety. The primary pharmaceutical therapeutic agents for anxiety are selective serotonin reuptake inhibitors. Anxiety is prevalent in the general population and generalized anxiety disorder (GAD) is a common form of anxiety. This study explores the impact of GAD on the outcomes of adult patients hospitalized with UGIB. Methods Adult UGIB patients were selected utilizing the National (Nationwide) Inpatient Sample database from year 2014 and International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes. The outcomes of UGIB patients with and without GAD were investigated. The outcomes explored include inpatient mortality, hypotension/shock, acute renal failure, acute hepatic failure, acute respiratory failure and acute myocardial infarction. A multivariate logistic regression analysis was used to determine if GAD is an independent predictor of the outcomes. Results Among 19,850 UGIB patients studied, 2357 had comorbid GAD. GAD was identified as a risk factor for acute renal failure (adjusted odds ratio [aOR] 1.37, 95% confidence interval [CI] 1.30-1.57, p < 0.05) and inpatient mortality (aOR 1.50, 95% CI 1.01-2.06, p < 0.05). The aORs of hypotension/shock, acute hepatic failure, acute respiratory failure and acute myocardial infarction were not statistically significant. Conclusion UGIB patients with comorbid GAD are at elevated risk of inpatient mortality and acute renal failure. These results may gain increasing relevance as GAD prevalence has increased since the start of the coronavirus disease 2019 (COVID-19) pandemic.
