Emergency department frequentation and unscheduled readmissions within the first year after liver transplantation, and their impact on survival.

The goal of this research was to assess emergency room frequentation and visit causes, and unscheduled readmissions within the first year after liver transplantation discharge from hospital, as well as their impact on graft and patient survival. This was a retrospective study of the medical records of 98 patients (mean age, 55.6 ± 8.59 years, 77.6 % males) who were consecutively discharged from hospital after receiving a first liver transplant in our institution during the period 2012-2015. All visits to the emergency room during the first year after transplantation were analyzed, and survival at two years after transplantation was calculated. Fifty-six of all 98 patients (57.15 %) visited the emergency room on 117 occasions within the first year post-transplantation. Fever (n = 34; 29.05 %) and digestive symptoms (n = 32; 27.35 %) were the most common causes of consultation, and resulted in over half of visits. Thirty-five of these 56 patients (62.5 %) required urgent readmission during 50 of all 117 (42.7 %) visits, primarily because of infectious complications (44 %) diverse causes (bacterial pneumonia, cholangitis, Clostridium difficile colitis), and biliary tract-related issues. The likelihood of readmission increased from 11.22 % at 30 days after discharge to 22.4 % at 90 days after discharge. Patient survival at 1 and 2 years after transplantation was lower for patients who were readmitted (88.4 % and 80.7 %, respectively) when compared to those who were not (95.56 % and 91.17 %, respectively, p = 0.002).
