Pediatric length-of-stay index following liver transplantation

Area of Science:

• Pediatric Gastroenterology and Hepatology
• Transplant Surgery
• Health Services Research

Background:

• Pediatric End-Stage Liver Disease (PELD) scores aim to reduce waitlist mortality but do not accurately predict prolonged length-of-stay (LOS) or associated costs.
• Current scoring systems lack precision in identifying pediatric liver transplant recipients at high risk for extended hospitalizations.

Purpose of the Study:

• To develop and validate a novel pediatric length-of-stay (LOS) index.
• To accurately predict the risk of prolonged hospital stay following pediatric liver transplantation.

Main Methods:

• Utilized univariate and multivariate analyses on a large dataset of 5669 pediatric liver transplant recipients.
• Identified independent recipient and donor risk factors associated with prolonged stay (>30 days) using multiple imputation for missing variables.

Main Results:

• Developed a LOS index incorporating 13 donor/recipient factors, achieving a C-statistic of 0.72 for predicting prolonged stay.
• Significant predictors of prolonged LOS included ICU admission, recipient bilirubin levels >32, and pre-transplant hemodialysis.
• The index demonstrated effective discrimination across different patient risk quartiles.

Conclusions:

• The pediatric LOS index provides a validated tool to assess the risk of prolonged hospitalization after liver transplantation in children.
• Key predictive factors include pre-transplant hemodialysis, ICU admission, recipient weight, bilirubin levels, and life support status.
• This index can aid in resource allocation and patient management strategies for pediatric liver transplant recipients.
