Welfare cost of childhood- and adolescent-onset epilepsy: A controlled national study.

OBJECTIVES: Epilepsy is associated with a significant burden to patients and society. We calculated the factual excess in direct and indirect costs associated with childhood- and adolescent-onset epilepsy.

METHODS: Using records from the Danish National Patient Registry (1998-2002), we identified 3123 and 5018 patients with epilepsy aged 0-5years and 6-20years at the time of diagnosis, respectively. The two age groups of patients with epilepsy were matched to 6246 and 10,036 control persons without epilepsy, respectively, by gender, age, and geography. The controls were randomly chosen from the Danish Civil Registration System. Welfare costs included outpatient services, inpatient admissions, and emergency room visits based on the Danish National Patient Registry and information from the primary health-care sector based on data from the Danish Ministry of Health. This allowed the total health-care cost of epilepsy to be estimated. The use and costs of drugs were based on data from the Danish Medicines Agency. The frequencies of visits to outpatient clinics and hospitalizations and costs from primary sectors were based on data obtained from the National Patient Registry.

RESULTS: Children with epilepsy had higher welfare costs than controls. The highest cost was found one year after diagnosis, with higher costs up to 10years after diagnosis compared with controls. Children aged 0-5years incurred greater health-care costs than those aged 6-20years.

CONCLUSION: Epilepsy has major socioeconomic consequences for the individual person with epilepsy and for society.
