Abstract

Background: Alcoholic liver cirrhosis (ALC) is a chronic liver disease with varying disease severity. Readmissions of ALC are associated with poor outcomes.

Aim: To identify and assess trends of readmissions for ALC over an eight-year period.

Methods: This retrospective interrupted trend study analysed 30-d readmissions of ALC in the United States from 2010 to 2018 using the National Readmissions Database. Hospitalization for ALC was the reason for index admission obtained using the International Classification of Diseases codes (571.2 and K70.3X). Biodemographic characteristics and hospitalization trends were highlighted over time. A multivariate regression analysis model was used to calculate the trend for risk-adjusted odds of 30-d all-cause ALC readmissions, ALC specific readmission rate, ALC readmission proportion, inpatient mortality, mean length of stay (LOS) and mean total hospital cost (THC) following adjustments for age, gender, grouped Charlson Comorbidity Index, insurance, mean household income, and hospital characteristics.

Results: There was a trend towards increasing total 30-d readmissions of ALC from 7660 in 2010 to 15085 in 2018 (P < 0.001). Patients readmitted for ALC were noted to have an increasing comorbidity burden over time. We noted a rise in the risk-adjusted 30-d all-cause readmission of ALC from 24.9% in 2010 to 29.9% in 2018 (P < 0.001). ALC-specific readmission rate increased from 6.3% in 2010 to 8.4% in 2018 (P < 0.001) while ALC readmission proportion increased from 31.4% in 2010 to 36.3% in 2018 (P < 0.001). Inpatient mortality for 30-d readmissions of ALC declined from 10.5% in 2010 to 8.2% in 2018 (P = 0.0079). However, there was a trend towards increasing LOS from 5.6 d in 2010 to 6.3 d in 2018 (P < 0.001) and increasing THC from 13790 dollars in 2010 to 17150 dollars in 2018 (P < 0.001). The total days of hospital stay attributable to 30-d readmissions of ALC increased by 119.2% while the total attributable hospital costs increased by 149% by the end of 2018.

Conclusion: There was an increase in the 30-d readmission rate and comorbidity burden for ALC; however, inpatient mortality declined. Additionally, there was a trend towards increasing LOS and THC for these readmissions.
