Hospital-Acquired Conditions after Liver Transplantation.

Hospital-acquired conditions (HACs) are used to define hospital performance measures. Patient comorbidity may influence HAC development. The National Inpatient Sample database was used to investigate HACs for the patients who underwent liver transplantation. Multivariate analysis was used to identify HAC risk factors. We found a total of 13,816 patients who underwent liver transplantation during 2002-2014. Of these, 330 (2.4%) had a report of HACs. Most frequent HACs were vascular catheter-associated infection [220 (1.6%)], falls and trauma [66 (0.5%), catheter-associated UTI [24 (0.2%)], and pressure ulcer stage III/IV [22 (0.2%)]. Factors correlating with HACs included extreme loss function (AOR: 52.13, P < 0.01) and major loss function (AOR: 8.11, P = 0.04), hepatopulmonary syndrome (AOR: 3.39, P = 0.02), portal hypertension (AOR: 1.49, P = 0.02), and hospitalization length of stay before transplant (AOR: 1.01, P < 0.01). The rate of HACs for liver transplantation is three times higher than the reported overall rate of HACs for GI procedures. Multiple patient factors are associated with HACs, and HACs may not be a reliable measure to evaluate hospital performance. Vascular catheter-associated infection is the most common HAC after liver transplantation.
