Abstract

Objectives: To examine in liver transplant recipients at centers participating in the Pediatric Health Information System dataset the number of hospitalizations for respiratory syncytial virus (RSV) and vaccine-preventable infections (VPIs) in the first 2 years after transplantation, morbidity and mortality associated with these hospitalizations, and costs associated with these hospitalizations.

Study design: A retrospective cohort study of patients <18 years of age who underwent liver transplantation at a Pediatric Health Information System center between January 1, 2004, and December 31, 2012. Hospitalizations for RSV/VPIs during the first 2 years post-transplant were ascertained using International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes. Data were collected on clinical care, outcomes, and costs during these hospitalizations.

Results: There were 2554 liver transplant recipients identified; 415 patients (16.3%) had 544 cases of RSV/VPIs. RSV, rotavirus, and influenza were the most common infections resulting in hospitalization. Ninety-two patients (3.6%) had RSV/VPI during their transplant hospitalization. Transplant hospitalizations complicated by RSV/VPI were longer (44 days vs. 21 days; P < .001), had higher rejection rates (37% vs. 26%; P = .02), and were more expensive ($259 697 vs. $190 860; P < .001). Multivariate analyses identified age <2 years at transplant (P < .001) and multivisceral recipient (P = .04) as predictors of a hospitalization for RSV.

Conclusions: VPIs occurred in 1 of 6 liver transplant recipients in the first 2 years post-transplant, a significantly higher rate than in the general pediatric population. These hospitalizations had substantial morbidity, mortality, and costs, demonstrating the importance of vaccinating patients before transplantation.
