Factors predicting lower hospital stay after liver transplantation using a comprehensive enhanced recovery after surgery (ERAS) protocol

Abstract

Introduction: Enhanced recovery after surgery (ERAS) protocols facilitate patient recovery without increasing complication rates. An ERAS protocol designed for our liver transplant (LT) patients obtained a median hospital length of stay (LOS) of 4 days. However, a proportion of patients do not achieve early discharge. This study aimed to identify factors that predict an LOS≤ 4 days.

Methods: Identifying factors associated with LOS <4 days in our LT patients.

Results: We performed 293 LTs (2012-2021), LOS≤4 days in 171 (58.4 %). The following factors emerged as statistically predictors of LOS≤4 days in the univariate analysis: male sex, HCC or HCV patients, lower MELD score, lower BAR score, no DCD patients, shorter operative time, no intraoperative transfusion, shorter ICU stay, no Clavien-Dindo complications grade ≥ III, no primary graft dysfunction, no acute rejection, no readmission at 30 days and no retransplantation were associated to LOS≤4 days. However, in the multivariate analysis, the only independent risk factor that predicted LOS≤4 days was the presence of hepatocarcinoma. DCD donors and higher MELD score were negative factors.

Conclusions: Applying ERAS programs in LT patients is beneficial, safe and extensible to all patients, but those with hepatocarcinoma obtain higher rates of LOS≤4 days.
