Chronic kidney disease is associated with angiodysplasia of gastrointestinal tract leading to increased risk of gastrointestinal bleeding.
To determine the nationwide prevalence, trends, predictors and resource utilization of angiodysplasia-associated gastrointestinal bleeding in end-stage renal disease hospitalizations.
The Nationwide Inpatient Sample database from 2009 to 2014, was utilized to conduct a retrospective study on patients with angiodysplasia associated- gastrointestinal bleeding and end-stage renal disease. Hospitalizations with end-stage renal disease were included in the Nationwide Inpatient Sample database and a subset of hospitalizations with end-stage renal disease and angiodysplasia-associated gastrointestinal bleeding were identified with International Classification of Diseases, 9th revision, Clinical Modification codes for both end-stage renal disease (585.6) and Angiodysplasia (569.85, 537.83).
The prevalence of angiodysplasia-associated gastrointestinal bleeding was 0.45% (n = 24709) among all end-stage renal disease patients (n = 5505252) that were hospitalized. Multivariate analysis indicated that the following were significant factors associated with higher odds of angiodysplasia associated-gastrointestinal bleeding in end-stage renal disease patients: an increasing trend from 2009-2014 (P < 0.01), increasing age (P < 0.0001); African American race (P = 0.0206); increasing Charlson-Deyo Comorbidity Index (P < 0.01); hypertension (P < 0.0001); and tobacco use (P < 0.0001). Diabetes mellitus (P < 0.0001) was associated with lower odds of angiodysplasia associated-gastrointestinal bleeding in end-stage renal disease patients. In comparison with urban teaching hospitals, rural and urban nonteaching hospitals were associated with decreased odds of angiodysplasia associated-gastrointestinal hemorrhage.
Angiodysplasia-associated gastrointestinal bleeding in end-stage renal disease patients showed an increasing trend from 2009-2014. Advanced age, African American race, overall high comorbidities, hypertension and smoking were significant factors for angiodysplasia-associated gastrointestinal bleeding in end-stage renal disease hospitalized patients.
Core tip: There was an increasing trend of angiodysplasia associated-gastrointestinal bleeding among end-stage renal disease patients over the study period of 2009-2014. The likelihood of angiodysplasia associated-gastrointestinal bleeding significantly increased with advanced age with the highest likelihood occurring in patients above the age of 75 years. African American race, increased co-morbidities, hypertension and tobacco use were independent predictors of angiodysplasia associated-gastrointestinal bleeding in end-stage renal disease hospitalized patients.
