    Abstract:
    BACKGROUND: Liver transplantation is a standard of care for treatment of end-stage liver disease. The aim of this study was to evaluate resource utilization for patients admitted to the U.S. hospitals for liver transplantation from 2005 to 2009. METHODS: Nationwide inpatient sample was used. RESULTS: A total of 5527 hospital admissions were included to the study cohort approximating 27,350 procedures nationwide (compared with 32,228 reported by United Network for Organ Sharing). Approximately 75% of patients had major or extreme severity of illness (All Patient Refined Diagnosis-Related Groups). The most prevalent comorbidities were coagulopathy (36.0%), fluid and electrolyte disorders (39.8%), anemia (18.7%), and type 2 diabetes (23.8%). Furthermore, 5.1% patients died in the hospital, 80.0% were discharged routinely or to home healthcare, and 14.9% were transferred to other healthcare facilities. The mean number of inpatient procedures was 7.2, and 3.5 were minimal therapeutic. The mean length of hospitalization was 22.2 days, the mean hospital charges were $358,200, and the mean inpatient costs of liver transplantation were $114,300. In multivariate analysis, the most significant factors associated with longer stay were younger age, major or extreme severity of illness, and more procedures performed during hospitalization. Similar factors were also associated with higher cost of inpatient treatment. Inpatient mortality, however, was associated only with more severe illness and more procedures while being inversely associated with younger age and higher income. CONCLUSIONS: Liver transplantation is a life-saving procedure with significant economic burden to our society. Severity of illness is the common driver of both in hospital mortality and resource utilization.
