RESUMO
BACKGROUND: Pediatric patients with kidney failure often experience cognitive delays. However, academic delay (being more than one grade level below age-appropriate grade, or in special education) after pediatric kidney transplantation (KTx) has not been explored. We sought to identify patient characteristics associated with a higher risk of academic delay 1 year post-KTx. METHODS: We used the United Network for Organ Sharing (UNOS) database to identify children aged 6-17 years who received a primary KTx between 2014 and 2021 and had a functioning graft 1 year after KTx. The primary outcome was the patient's academic progress at 1 year post-transplant. The secondary outcome was change in academic progress between transplant and 1-year follow-up: onset of new delay, resolution of pre-existing delay, persistence of delay, or no delay at either timepoint. Binomial and multinomial mixed effects logistic regression models were used to predict each outcome based on patient characteristics. RESULTS: The study included 2197 patients, of whom 14% demonstrated academic delay at 1 year post-KTx, 4% demonstrated a new onset of academic delay, 5% demonstrated a resolution of academic delay, and 10% demonstrated persistent academic delay. Patients undergoing transplantation at a younger age, receiving a deceased donor kidney, experiencing longer waitlist times, and undergoing KTx for vascular or other disease indications for KTx were more likely to experience academic delays, including new-onset academic delays. CONCLUSIONS: Academic delays are frequently reported among pediatric KTx recipients. Additional academic support may help resolving or preventing academic delay for at-risk subgroups of children undergoing KTx.
