Abstract

Hepatorenal syndrome (HRS) is one of the leading causes of hospitalizations in patients with chronic liver disease (CLD). We conducted a retrospective national database study to determine the epidemiology of HRS in hospitalized patients with CLD. Data from a Nationwide Inpatient Sample were extracted from 2002 to 2012 using ICD-9-CM codes related to CLD and HRS. The following outcomes were examined: in-hospital mortality, total charges, length of stay (LOS), patient demographics, procedures, complications, and comorbidities. Statistical analysis including regression was performed to examine factors associated with HRS. During 2002-2012, hospital discharges related to CLD increased from 407,246 to 836,475 with an increase of 37.9% for HRS as a complication in this population. Patients with CLD and HRS had worse outcomes compared with patients with CLD without HRS. This was manifested as a higher mortality rate (32.0% vs 10.3%), increased LOS (median 7 vs 5 days), and increased hospital costs (median $16,000 vs $11,000). Logistic regression demonstrated that HIV/AIDS (adjusted OR 2.9, 95% CI 2.2 to 3.9), pneumonia (aOR 2.8, 95% CI 2.3 to 3.2), and esophageal variceal bleeding (aOR 1.9, 95% CI 1.7 to 2.0) were associated with higher mortality in patients with HRS. Conversely, liver transplantation (aOR 0.1, 95% CI 0.1 to 0.1), transjugular intrahepatic portosystemic shunt (aOR 0.5, 95% CI 0.4 to 0.6), and hospitalization in the Midwest region of the USA (aOR 0.7, 95% CI 0.6 to 0.7) were associated with reduced mortality. The incidence of HRS in hospitalized patients with CLD increased during 2002-2012. HRS is associated with significant mortality and morbidity in these patients.
