Abstract
Introduction Hepatic encephalopathy (HE) is a common complication of cirrhosis and a common reason for hospital admission. We aimed to determine whether expert consultation from gastroenterology (GI) leads to better clinical outcomes for inpatients with HE. Methods A retrospective review was performed of all adult patients (age ≥ 18) admitted with HE to a tertiary care hospital between January 2013 and April 2018. Patients who received a GI consult were compared to patients who did not receive a GI consult (No consult group). The primary outcome was hospital length of stay (LOS); secondary outcomes were rates of 30-day hospital readmission and 90-day mortality. Multivariate analysis was conducted to adjust for known confounders. Results Four hundred and twenty-five patients (814 encounters) were included in the study; of these, 236 patients had received a GI consultation for HE. Patients in the GI consult group were younger (mean age 55 vs 58 years, p= 0.02) and had higher Model For End-Stage Liver Disease-sodium (MELD-Na) score (mean MELD-Na 23.5 vs 17.5, p<0.01) compared to patients who did not receive GI consultation. The precipitants of HE were significantly different between the groups: there was more spontaneous bacterial peritonitis (SBP) and GI bleeding (GIB) in the GI consult group and more lactulose non-adherence in the no consult group. There was no difference in the etiology of liver disease between the two groups. Median LOS for the GI consult group was six days vs three days in the no consult group (p<0.01); the incidence rate ratio was 1.79 (95%CI 1.59-2.02, p<0.01) on multivariate analysis. There was no difference in 30-day readmission or 90-day mortality between the two groups. Conclusion GI consultation for patients with HE admitted to a hospital medicine service may be associated with longer LOS. In selected patients admitted with HE, GI consultation may not be necessary to achieve good clinical outcomes.
