BACKGROUND: Patients with hepatitis C virus infection often require hospitalization for progressive liver disease and complications, incurring high cost and risk of death.
GOALS: The aim of our study was to investigate recent trends in the economic burden and outcomes of patients hospitalized for hepatitis C in the United States.
STUDY: Patients with hepatitis C-associated hospitalization were identified from the Nationwide Inpatient Sample 2005 to 2011. We analyzed the in-hospital mortality, hospital service utilization, demographic, and clinical features of patients. A prognostic model to predict in-hospital survival and death with independent risk factors for mortality was developed.
RESULTS: A total of 607,279 cases of hepatitis C-associated hospitalization were identified. Over 7 years, the annual hospitalized volume increased by 28.8%. In-hospital mortality declined from 8.2% to 6.4%. Median length of stay (4 d) was unchanged but the inflation-adjusted hospital charges increased by 33.3%. Acute respiratory failure was the greatest independent risk factor for mortality [odds ratio (OR)=7.3; 95% confidence interval (CI), 7.0-7.5], followed by septicemia (OR=4.1; 95% CI, 4.0-4.3), renal failure (OR=3.4; 95% CI, 3.3-3.5), and acute liver failure (OR=2.9; 95% CI, 2.7-3.0). On the basis of the major risk factors for mortality, a risk-adjusted model was developed that could predict the in-hospital outcome of hepatitis C patients with an accurate rate of 89.2%.
CONCLUSIONS: Despite decreasing in-hospital mortality, both hospital volume and charges related to hepatitis C increased from 2005 to 2011. Use of a risk-adjusted model could help predict mortality and improve outcomes of hepatitis C inpatients.
