Abstract

Introduction: Angiodysplasia is the most common vascular lesion of the gastrointestinal (GI) tract. However, limited epidemiological data exists on hospitalizations related to angiodysplasia of the intestine (ADOI) in the United States (U.S.). The aim of this study is to analyze inpatient trends and outcomes in hospitalizations with ADOI. Methods: We analyzed the National Inpatient Sample (NIS) database for all subjects with discharge diagnosis of angiodysplasia of the intestine with or without hemorrhage (ICD-9 code 569.85 and 569.84 respectively) as principal and/or secondary diagnosis during the period from 2001 to 2011. Results: In 2001, there were 39,244 admissions with discharge diagnosis of ADOI as compared to 41,214 in 2011 (p <0.0001). Women (58.0%) were more commonly affected than men (42.0%) (p < 0.0001). Overall in-hospital mortality rate was 2.2% for patients with ADOI with hemorrhage and 1.6% for patients with ADOI without hemorrhage (p <0.0001). Mean cost of hospitalization increased from $10,701 in 2001 to $12,478 in 2011 (16.6% increase, p < 0.0001). Conclusion: The total number of hospitalizations with ADOI increased significantly with women having significantly higher hospitalization rates. Mortality rate was higher in hospitalizations with ADOI with hemorrhage than those without hemorrhage. There was a notable increase in the average cost of hospitalization.
