According to treatment received, patients were identified as users or nonusers of PPI. Clinical and laboratory data, complications during hospitalization, and overall survival were recorded in all the patients.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Of the 489 patients, 299 (61.1%) patients received PPI therapy. The logistic regression analysis showed that age, albumin, history of previous hepatic encephalopathy (HE), and the chronic liver failure-sequential organ failure assessment (CLIF-SOFA) score were independent risk factors for HE in patients with decompensated cirrhosis [odds ratio (OR) = 1.07, 95% CI: 1.03\u20131.12, <jats:italic>p<\/jats:italic> = 0.001; OR = 1.13, 95% CI: 1.04\u20131.24, <jats:italic>p<\/jats:italic> = 0.006; OR = 242.52, 95% CI: 40.17\u20131464.11, <jats:italic>p<\/jats:italic> &amp;lt; 0.001; and OR = 2.89, 95% CI: 2.11\u20133.96, <jats:italic>p<\/jats:italic> &amp;lt; 0.001, respectively]. Previous severe liver injury and previous bacterial infections were independent risk factors for spontaneous bacterial peritonitis (SBP) in patients with decompensated cirrhosis (OR = 3.43, 95% CI: 1.16\u201310.17, <jats:italic>p<\/jats:italic> = 0.026 and OR = 6.47, 95% CI: 2.29\u201318.29, <jats:italic>p<\/jats:italic> &amp;lt; 0.001, respectively).
