Hospitalizations and costs associated with hepatitis C and advanced liver disease continue to increase.

Disease burden models have predicted worsening morbidity of liver disease caused by hepatitis C in the United States. The aim of this study was to determine the trend in hospitalizations caused by hepatitis C and advanced liver disease. We analyzed data for the period 2004-11 from the Nationwide Inpatient Sample, the largest nationwide all-payer hospital inpatient care database. Hospitalization rates for hepatitis C per 100,000 people increased significantly from 4.76 in 2004-05 to 13.81 in 2010-11-an increase of 190 percent. Hospitalization rates for advanced liver disease also increased, particularly for hepatorenal syndrome (93 percent) and portal hypertension (62 percent). Hepatitis C was the principal diagnosis for 64,867 hospitalizations in 2010-11, resulting in a total charge of $3.5 billion. We found nationwide trends in increasing morbidity and medical costs for advanced liver disease associated with hepatitis C. Our findings suggest that hepatitis C is a public health problem and has been growing in magnitude in recent years. Stakeholders and policy makers should implement both recommended screenings for people born in the period 1945-65 and more effective treatment for hepatitis C, which have the potential to reverse the rising morbidity and costs of hepatitis C.
