#Renal Failure is Associated With Increased Mortality and Hospital Utilization in Patients Admitted With Nonalcoholic #Steatohepatitis

We aimed to investigate the mortality and hospital utilization outcomes of hospitalized nonalcoholic steatohepatitis (NASH) patients with and without kidney failure in a nationwide cohort..

..The overall sample included 7,135,090 patients. Among 6855 patients admitted for NASH, 598 or 8.7% had comorbid kidney failure. After multivariate regression analysis, NASH patients with renal failure had increased in-hospital mortality [odds ratio=28.72, 95% confidence interval (CI): 8.99-91.73], length of stay (Ξ²=3.02, 95% CI: 2.54-3.5), total hospital charges (Ξ²=$37,045, 95% CI: $31,756.18-$42,335.62). Positive predictors of mortality in the renal failure group were Charlson Comorbidity Index β‰₯3 [adjusted odds ratio (aOR)=3.46, 95% CI: 1.04-11.51], variceal bleeding (aOR=3.02, 95% CI: 1.06-8.61), and hepatic encephalopathy (aOR=26.38, 95% CI: 1.29-540.56). Predictors of decreased mortality were Medicaid (aOR=0.047, 95% CI: 0.28-0.79) and private insurance (aOR=0.56, 95% CI: 0.38-0.83).

Conclusions:
The prevalence of renal failure in NASH hospitalizations is associated with markedly increased mortality, hospital costs, and length of stay. As a result, clinicians should be vigilant in treating kidney failure in this population.
