Outcomes among inpatients with cirrhosis and infection in the modern era: results from an analysis of the National Inpatient Sample.

Background: Patients with cirrhosis are at increased risk of infection (CDI). We analyzed outcomes and healthcare utilization in hospitalized cirrhotic patients with CDI.

Methods: The Nationwide Inpatient Sample from 2016-2017 identified 8245 hospitalized patients with a concurrent diagnosis of cirrhosis and CDI. Our primary outcome was in-hospital all-cause mortality. Secondary outcomes were length of stay (LOS), hospitalization charges and costs, shock, sepsis, acute kidney injury (AKI), intensive care unit (ICU) admission, and home discharge.

Results: There was no significant difference in all-cause in-hospital mortality between patients with cirrhosis compared to patients without cirrhosis (adjusted odds ratio [aOR] 1.31, 95% confidence interval [CI] 0.89-1.93; P=0.16). Patients with cirrhosis had a slightly but statistically significantly longer mean LOS (+0.57 days, P=0.001). The adjusted difference in mean hospitalization charges was greater in patients with cirrhosis ($+4094, 95%CI $1080-7108; P=0.008), as was the mean hospitalization cost ($+1349, 95%CI $600-2098; P<0.001). There was no difference in the likelihood of sepsis, ICU admission, or home discharge between the groups. Patients with cirrhosis were significantly less likely to develop AKI (aOR 0.82, 95%CI 0.72-0.93; P=0.003).

Conclusions: Mortality outcomes associated with CDI have improved over time. Patients with cirrhosis continue to exhibit greater LOS and hospital costs.
