Elevated Incidence and Risk of Emergent Cirrhosis Complications in Alcoholic Cirrhosis Compared with Other Etiologies

Gastrointestinal bleeding (GIB) is a common cause of urgent hospitalization in patients with cirrhosis. However, limited studies have examined the prevalence and risk of these complications based on etiology. This study aims to compare the occurrence and risk of cirrhosis complications on inpatient mortality between alcoholic cirrhosis (ALC) and other etiology-induced cirrhosis (NALC). This retrospective analysis included 7,159,694 patients. ALC was diagnosed based on ICD-10, while NALC included primary and secondary biliary cirrhosis, nonalcoholic steatohepatitis (NASH), and unspecified cirrhosis of the liver. GIB included bleeding from esophageal and gastric varices. Bivariate analyses using appropriate statistical tests were performed to compare the two groups. ALC patients had a significantly higher incidence of GIB compared with NALC patients (10.8% vs. 6.4%, p < 0.01), with an associated 60% higher risk of GIB than NALC patients (p < 0.01). ALC was associated with a higher prevalence of ascites (45.6% vs. 27.9%, p < 0.01) and hepatic encephalopathy (HE) (45.5% vs. 27.2%, p < 0.01) compared with NALC patients. The risk of ascites and HE was 2.2 times and 2.3 times higher, respectively, in ALC patients compared with NALC patients (p < 0.01). Furthermore, ALC patients had higher hospital mortality rates compared with NALC patients, with a 47% higher risk of hospital mortality after adjustment (p < 0.01). ALC patients also had prolonged hospital stays, higher charges, more emergency room (ER) visits, and more frequent esophagogastroduodenoscopy (EGD) requirements compared with those of NALC patients (p < 0.01). ALC patients have a significantly higher risk of developing GIB, ascites, and HE compared with NALC patients, leading to increased mortality and greater medical burden on hospitals.
