Cirrhosis is associated with worse outcomes in peptic ulcer bleeding (PUB). There are no population-based studies from the United States on the impact of cirrhosis on PUB outcomes.To investigate the impact of cirrhosis on outcomes of patients with PUB.Cross-sectional study.Nationwide Inpatient Sample 2009.International Classification of Diseases, the 9th revision, codes were used to identify patients with PUB and cirrhosis. The control group was patients with PUB without cirrhosis.In-hospital mortality, length of stay, and hospitalization costs.A total of 96,887 discharges with PUB as a diagnosis were identified—3574 with PUB and cirrhosis and 93,313 with PUB alone without cirrhosis. Mortality of PUB with concomitant cirrhosis was higher than in the control group without cirrhosis (5.5% vs 2%; P = .01); decompensated cirrhosis had higher mortality than did compensated cirrhosis (6.6% vs 3.9%; P = .01). In multivariate analysis, the presence of cirrhosis independently increased mortality (adjusted odds ratio (aOR) 3.3; 95% confidence interval [CI], 2.2-4.9). Stratified analysis showed that decompensated cirrhosis (aOR 4.4; 95% CI, 2.6-7.3) had higher mortality than compensated cirrhosis (aOR 1.9; 95% CI, 1.04-3.6). There was no difference in the proportion of patients who underwent endoscopy within 24 hours (51.9% vs 51.1%; P = .68) between those with cirrhosis and controls. Patients with cirrhosis received less surgical intervention (aOR 0.8; 95% CI, 0.6-0.9) compared with controls. Hospitalization costs also were increased in patients with decompensated cirrhosis.Administrative data set.Both decompensated and compensated cirrhosis are associated with increased mortality in patients with PUB.
