Transition from pediatric to adult care system in patients with complex epilepsies: Necker model for transition...

Complex epilepsies such as epileptic and developmental encephalopathies require multidisciplinary care throughout life. A coordinated transition program is therefore essential to provide optimal support for patients leaving pediatric for adult care. The aim of this study is to describe and evaluate our transition program for complex epilepsies, focusing on the last step in this program, that is, the multidisciplinary transition day hospital (MTDH).

We performed a retrospective observational study including patients with complex epilepsies who underwent the full steps of the transition program at Necker-Enfants Malades Hospital between May 2021 and June 2023, with a follow-up until February 2024. We described the cohort and detailed the interventions performed during the MTDH including medical, medicosocial, educational, daily life abilities, and laboratory and imaging assessments with the participation of one member of the adult team. We evaluated two indicators of our program: (1) the "adult first clinic attendance rate," defined by the percentage of patients attending their first adult clinic; and (2) the "return rate," defined by the percentage of patients who requested a pediatric encounter after their transfer.

Our cohort included 70 patients with a mean age of 19.1 years (interquartile range = 16.3-19.5). Eighty percent had an epilepsy syndrome diagnosis; 72.8% were treated with three or more antiseizure medications. All patients had their appointment at the adult clinic within 6 months of the day hospital, and only two families requested a pediatric encounter after the transfer.

The transition program is key for an optimal transfer of patients with complex epilepsies to adult care. It requires a comprehensive multidisciplinary approach and provides a complete summary of the medical record. Our program secures a smooth landing in adult care and is a promising model to better manage the challenging transition process, especially in patients with complex epilepsy.
