Background: Alcoholic hepatitis (AH) readmissions are commonly secondary to relapse to alcohol use after discharge from the hospital.

Methods: This retrospective interrupted trend study analyzed the National Readmissions Database (NRD) from 2010 to 2018 to identify 30-day readmissions of AH using the International Classification of Diseases (ICD)-9 and ICD-10 codes (571.1 and K70.1). Individuals < 18 years, elective and traumatic readmissions were excluded. The biodemographic characteristics and hospitalization trends were highlighted over an 8-year time frame. A multivariate regression analysis was used to calculate the risk-adjusted odds of trends for all-cause 30-day readmissions, AH-specific readmissions, inpatient mortality, mean length of stay (LOS), and mean total hospital charge (THC) after adjusting for age, gender, grouped Charlson Comorbidity Index (CCI), type of insurance, mean household income, and hospital characteristics. P-values ? 0.05 were considered statistically significant.

Results: We noted an increasing trend for total 30-day readmissions of AH from 1,839 in 2010 to 3,784 in 2018 (P-trend < 0.001). Males made up a majority of the population; however, gender distribution was not statistically significant. Additionally, 30-day AH readmissions had an increasing comorbidity burden with time. The 30-day all-cause readmission rate increased from 18.8% in 2010 to 24.4% in 2018 and AH-specific readmission rate from 2.9% in 2010 to 3.9% in 2018 without a statistically significant trend. However, we noted a declining risk-adjusted trend of inpatient mortality for 30-day readmissions of AH from 8.7% in 2010 to 7.4% in 2018 (P-trend = 0.022). Furthermore, the total LOS attributable to 30-day readmissions of AH increased by 132.5% from 11,275 days in 2010 to 26,220 days in 2018 and the attributable THC increased by 160.9% to over $67 million in 2018.

Conclusions: For 30-day AH readmissions, inpatient mortality declined to 7.4% in 2018, while the total number of hospitalizations, LOS and THC increased from 2010 to 2018.
