Transition from pediatric to adult care in a Japanese cohort of childhood-onset epilepsy: prevalence of epileptic syndromes and complexity in the transition

Transition in epilepsy - A pilot study with patients in and outside of academic centers

RATIONALE

Epilepsy is a complex condition and seizures are only one part of this disease. The move from pediatric to adult healthcare system proves difficult for many adolescents with epilepsy and their families. The challenges increase when patients have epilepsies associated with intellectual and/or developmental disabilities, autism spectrum disorder, and motor disorders. Knowledge and system gaps may exist between the two systems, adding to the challenges. The main goal of this study is to understand the perception of patients with epilepsy and their families who were preparing to move from pediatric to adult healthcare system or had already moved.

METHODS

A survey was distributed to patients/caregivers of patients with epilepsy through patient support groups in North America and in-person through the 2019 Epilepsy Awareness Day at Disneyland. Patients were required to be 12 years or older at the time of the survey and were divided into two groups: those between 12 and 17 years and those 18 years or older. Caregivers answered on behalf of patients who were unable to respond (e.g., intellectual disability). Major components of the survey included demographics, epilepsy details, quality and access to care received in pediatric and adult years, and questions regarding transition and readiness.

RESULTS

Responses were received from 58 patients/caregivers of patients with epilepsy from Canada and the United States. In group A (patients between 12 and 17 years), none of the 17-year-old patients were spoken to about transition. Patients (caregivers) with epilepsy and intellectual and/or developmental disabilities (IDD) had less time to discuss important things during the transition/transfer phase than patients with normal intelligence. Finally, there was a statistically significant difference observed in access to specialty care reported in the adult years, compared to the years in the pediatric system. In the group B (patients 18 years and older) a) 35 % still visit their family doctor for epilepsy related treatment despite the majority being on 2 or more antiseizure medications (ASMs); b) 27 % of patients in this group were still being followed by their pediatric neurologist; c) one patient received care only through visits to the emergency department; d) only 4 % felt that they received clear instructions during transfer of care such as knowing the name of the adult healthcare practitioner and/or the name of the care institution they were being transferred to.

CONCLUSIONS

This study highlights the lack of appropriate transition to adult healthcare system (AHCS) amongst an unselected group of patients with epilepsy in Canada and United States. An overwhelming majority of patients followed in the community and in academy centers were simply "transferred" to an adult health practitioner, or they remained under the care of pediatricians. Finally, most patients lack access to significant social and medical support after moving to the AHCS.

Characteristics of an advanced epilepsy treatment gap in a region in Japan

To investigate the quality of epilepsy care in a region in Japan that lacked specialised care, we retrospectively evaluated patients who visited our newly established epilepsy division between April 2018 and March 2021, and had been treated with anti-seizure medications (ASMs) for at least 1 year prior. Of the 231 patients included, 169 had ongoing seizure episodes at first visit (seizure-persist group) and 62 had no seizure episodes for more than a year (seizure-free group). Eighty-three patients in the seizure-persist group had not received specialised epilepsy care, 15 had been treated with unnecessary medications, and seven had experienced side effects from ASMs. Twelve patients in the seizure-free group had been treated with unnecessary ASMs, 10 had been treated with ASMs with teratogenic potential and four had experienced ASM side effects. These patients could be classified as having an advanced epilepsy treatment gap (ETG) because they had not previously received necessary specialised care. The progressive decline in the number of patients with advanced ETG suggests that our new epilepsy division has addressed this issue. This study highlights that a significant number of patients with advanced ETGs exist in Japan and that proper countermeasures are required to address this gap.

Transition to adult care in epilepsy: A systematic review

The transfer from paediatric to adult care can be a complex process in children with epilepsy. Inadequate care during this phase can affect long-term medical and psychosocial outcomes. The aim of this study was to review studies on transitional care from paediatric to adult healthcare for young persons with epilepsy in order to synthesize evidence for best practice. We undertook a systematic review following PRISMA guidelines and employed narrative synthesis. A total of 36 articles were included, of which 11 were interventional studies and 25 observational studies. Study quality was rated as 'good' for only four studies. Interventions included joint or multidisciplinary clinics, education (patient and health professional education) and extended service provision (Saturday clinics, peer-groups). All studies observed a positive effect experienced by the participants, regardless of intervention type. Observational studies showed that transition plans/programmes are asked for but frequently not existing or not adapted to subgroups with intellectual disability or other neurodevelopmental conditions. The results of this systematic review on transitional care in epilepsy suggest that a planned transition process likely enhances medical and psychosocial outcomes for young people with epilepsy, but the body of evidence is limited and there are significant gaps in knowledge of what efficacious transition constitutes. More studies are needed employing qualitative and quantitative methods to further explore the needs of young people with epilepsy and their families but also robust study designs to investigate the impact of interventions on medical and psychosocial outcomes.
