Telemedicine- versus outpatient-based initiation and management of ketogenic diet therapy in children with drug-resistant epilepsy during the COVID-19 pandemic.

Introduction: Initiation of ketogenic diet therapies (KDT) for pediatric epilepsy is usually done on an inpatient basis and the diet is managed during clinical appointments following a protocol of visits and routine tests. Because of the 2019 coronavirus disease (COVID-19) pandemic and the associated lock-down measures, we switched from outpatient to telemedicine-based KDT initiation.

Objective: To explore the feasibility, effectiveness, and safety of online KDT initiation and follow-up by comparing a group of children with drug-resistant epilepsy that was managed by telemedicine compared to a group that was treated on an outpatient basis.

Materials And Methods: An observational study was conducted in two groups of patients with drug-resistant epilepsy who initiated KDT and were followed up with an online versus an outpatient modality by the interdisciplinary KDT team of Hospital Pediatria JP Garrahan in Buenos Aires, Argentina. Dietary compliance, ketosis, retention rate, adverse effects, number of contacts, and clinical outcome were evaluated at 1, 3, and 6 months on the diet.

Results: Overall, 37 patients were included, of whom 18 started the KD by telemedicine and 19 on an outpatient basis. Minimum follow-up of the patients was 6 months. All patients received the classic ketogenic diet. No statistical differences between the two groups regarding efficacy and safety of the diet were found.

Conclusions: Our results support the feasibility and safety of initiating and management of KDT by telemedicine. Patients and their families should be carefully selected in order to guarantee a good outcome.
