Temporal trends of cirrhosis associated conditions

摘要

BACKGROUND Chronic liver disease and cirrhosis is the 12^(th) leading cause of death in the United States. Patients with decompensated-cirrhosis, especially with hepatic encephalopathy/coma(HC), have a higher rate of early readmission and contribute to higher healthcare cost.AIM To evaluate the national inpatient trends of discharges, mortalities and financial impacts associated with four common conditions of cirrhosis.METHODS The publicly available Healthcare Cost and Utilization Project National Inpatient Sample database was utilized to examine the temporal trends of total number of discharges, mortalities and inpatient costs related to hospitalization with a primary diagnosis of HC, transjugular intrahepatic portosystemic shunt(TIPS),esophageal varices with bleeding(EV) and spontaneous bacterial peritonitis(SBP) from 2005 to 2014. The ten-year temporal trends were assessed using simple linear regressions and multiple regression analysis. Two-sided P < 0.05 was considered statistically significant.RESULTS From 2005 to 2014, the total number of discharges with cirrhosis-associated complications trended up for HC, SBP and EV(HC by 70% increase, P < 0.0001;SBP by 819% increase, P = 0.0002; EV by 9% increase, P = 0.016), but not for TIPS(P = 0.90). HC related to viral hepatitis showed faster increase by 357%(P <0.0001) in comparison to HC not related to viral hepatitis by 33 %(P = 0.0006).Overall, in-hospital mortality rates for each condition decreased from 2005 to2014(HC by 29% reduction, P = 0.0024; SBP by 26% reduction, P = 0.0038; TIPS by 32% reduction, P = 0.021) except for EV(P = 0.34). After adjustment for inflation, aggregate cost of hospitalization for EV, HC, and SBP significantly increased by 20%, 86%, and 980%, respectively, from 2005 to 2014(all P < 0.02),while TIPS had trend toward decreasing cost by 3%(P = 0.95).CONCLUSION The number of hospitalizations and costs for some of the cirrhosis-associated conditions increased. However, the inpatient mortality rates for most of these conditions decreased.
