The costs of epilepsy in three different populations of patients with epilepsy

The purpose of this study was to estimate the costs of care in three different populations of patients with epilepsy (general practices (GP), University Hospital (UH), and Epilepsy Center (EC)), and to analyse the distribution of costs by type of services for each patient group. A cost diary was developed to obtain prospective information on epilepsy-attributable service use over a period of 3 months. Similar information over the previous 3 months was obtained from a cost questionnaire. In addition, a quality of life inventory (QOLIE-31) was used. Standard cost lists were applied for the valuation of the direct cost items. A sensitivity analysis was performed for certain cost items for which no reliable data were available. One hundred and sixteen patients with established epilepsy were included, and the mean costs per patient per month (in Euros) ranged from 52.08 to 357.63. Patients from GP appeared to have lower direct costs, spent less time in seeking or undergoing a treatment, and reported lower seizure frequencies and less severe seizure types than the patients from the other patient groups. Patients from the EC reported the highest productivity changes and unemployment rates and also had the lowest scores on the QOLIE-31. The cost items anti-epileptic drugs, hospital services, unpaid care, and transportation accounted for the majority of the total direct costs.
