Abstract
BACKGROUND: The Compassionate Access Scheme (CAS) being delivered through the Queensland Children's Hospital is designed to allow access to an investigational purified Cannabidiol oral solution to paediatric patients with severe refractory epilepsy. The objectives of this study were to conduct semi-structured interviews to: 1. Understand families' expectations and attitudes about the use of an investigational cannabinoid product for their child's seizures; 2. Understand families' perceptions of Cannabidiol's efficacy for their child's seizures; and other aspects of their child's behaviour, quality of life and/or cognition. METHODS: Children aged 2-18 years had been enrolled in, or were enrolled in a compassionate access scheme for Cannabidiol at the time of the study. Semi-structured interviews (n = 19) with parents or caregivers (n = 23) of children diagnosed with refractory epilepsy were voice-recorded, transcribed and analysed to generate common themes. RESULTS: Key themes emerged relating to seizure activity, family and school engagement, drug safety and legal access, efficacy, clinical support, social acceptance of the medication and program delivery. The use of Cannabidiol was perceived to have benefits in relation to reducing the severity and frequency of seizure activity for almost a third of patients experiencing refractory epilepsy. Participants described other benefits including improved social engagement, wakefulness and a reduction of side effects related to a reduction of conventional medication dosage. CONCLUSION: This study provided unique perspectives of families' experiences managing untreatable epilepsy, their experiences with conventional and experimental pharmacological treatments and health services. Whilst families' perceptions showed the use of Cannabidiol did not provide a therapeutic reduction in the seizure activity for all patients diagnosed with refractory epilepsy, it's use as an additional pharmacological agent was perceived to provide other benefits by some patient families.
