A Comparative Analysis of Bleeding Peptic Ulcers in Hospitalizations With and Without End-Stage Renal Disease

Abstract

Background: End-stage renal disease (ESRD) patients are highly susceptible to peptic ulcer bleeding (PUB). We aimed to assess the influence of ESRD status on PUB hospitalizations in the United States (USA).

Methods: We analyzed the National Inpatient Sample to identify all adult PUB hospitalizations in the USA from 2007 to 2014, which were divided into two subgroups based on the presence or absence of ESRD. Hospitalization characteristics and clinical outcomes were compared. Furthermore, predictors of inpatient mortality for PUB hospitalizations with ESRD were identified.

Results: Between 2007 and 2014, there were 351,965 PUB hospitalizations with ESRD compared to 2,037,037 non-ESRD PUB hospitalizations. PUB ESRD hospitalizations had a higher mean age (71.6 vs. 63.6 years, P < 0.001), and proportion of ethnic minorities i.e., Blacks, Hispanics, and Asians compared to the non-ESRD cohort. We also noted higher all-cause inpatient mortality (5.4% vs. 2.6%, P < 0.001), rates of esophagogastroduodenoscopy (EGD) (20.7% vs. 19.1%, P < 0.001), and mean length of stay (LOS) (8.2 vs. 6 days, P < 0.001) for PUB ESRD hospitalizations compared to the non-ESRD cohort. After multivariate logistic regression analysis, Whites with ESRD had higher odds of mortality from PUB compared to Blacks. Furthermore, the odds of inpatient mortality from PUB decreased by 0.6% for every 1-year increase in age for hospitalizations with ESRD. Compared to the 2011 - 2014 study period, the 2007 - 2010 period had 43.7% higher odds (odds ratio (OR): 0.696, 95% confidence interval (CI): 0.645 - 0.751) of inpatient mortality for PUB hospitalizations with ESRD.

Conclusions: PUB hospitalizations with ESRD had higher inpatient mortality, EGD utilization, and mean LOS compared to non-ESRD PUB hospitalizations.
