Trends and Outcomes of Alcoholic Liver Cirrhosis Hospitalizations in the Last Two Decades: Analysis of the Nationwide Inpatient Sample

Abstract

Background Liver cirrhosis is a major burden on the health care system. Alcohol is one of the most common etiologies of cirrhosis. The aim of our article is to examine the trends of alcoholic liver cirrhosis (ALC) hospitalizations over the past two decades. Methods This was a retrospective longitudinal study. Using the International Classification of Diseases, Ninth Revision, Clinical Modification/Procedure Coding System (ICD-9-CM/PCS) and the ICD-10-CM/PCS, the Nationwide Inpatient Sample (NIS) database was analyzed. We included 1998, 2003, 2008, 2013, and 2018 NIS databases. Using multivariate regression analysis, we examined trends of ALC hospitalizations including inpatient mortality, mean length of stay (LOS), and mean total hospital charges (THCs). Results We included 261,420 hospitalizations with ALC as the primary diagnosis for admission. There was a trend toward increasing hospitalizations over that period; they increased from 46,186 in 1998 to 69,970 in 2018 (P < 0.001). Moreover, there was a 2.1-fold increase in the mean THC in 2018 compared to 1998 (P < 0.001). On the other hand, inpatient mortality decreased from 12.8% in 1998 to 4.7% in 2018 (P < 0.001), and a trend of decreasing mean LOS was observed. The mean LOS decreased from 7.0 days in 1998 to 5.9 days in 2018 (P < 0.001). Conclusions Over the last two decades, there was a trend of increasing hospitalizations and THC. However, we noticed a trend toward decreasing inpatient mortality and LOS over that period, which might reflect in part an improvement in the medical care provided for these patients.
