Introduction: Incidence of and risk factors for early hospital readmission (EHR) are poorly defined in pediatric liver transplant recipients. Therefore, we evaluated EHR incidence and risk factors for pediatric liver recipients in a nationally representative sample.
Methods: Using the Society of Pediatric Liver Transplantation database, we retrospectively analyzed 2808 pediatric liver-only recipients transplanted 2011-2022. Recipient-, donor-, and center-level characteristics were evaluated as possible risk factors for EHR within 30 days of hospital discharge using multivariable modified Poisson regression.
Results: Overall, 23% (N = 642) of pediatric recipients experienced EHR. Independent risk factors for EHR include diabetes (adjusted relative risk [aRR] 2.33, 95% CI: 1.41-3.86, p = 0.001), history of malignancy (aRR 1.59, 95% CI: 1.19-2.11, p = 0.002), and shorter length of transplant hospitalization. Recipients in the shortest length of stay quartile (median [IQR] 8 [7-9] days) had a ninefold increased risk for EHR compared with recipients in the longest length of stay quartile (34 [28-48] days) (aRR 8.86, 95% CI: 5.68-13.81, p < 0.001). Incidence of EHR did not vary by transplant center and was not associated with other characteristics of the donor (DCD vs. not DCD), recipient (age, race, sex, and diagnosis), procedure (whole vs. split liver, ischemic time), or transplant center.
Conclusion: We found the 30-day readmission rate for pediatric liver transplant recipients was 23%. Shorter hospital stays were a major risk factor for EHR, highlighting that longer initial transplant hospital stays may be beneficial for predischarge optimization and coordination of their complex care.
