Summary Treatment with antiepileptic drugs is commonly guided by serum level mon-
itoring. Such monitoring requires expensive laboratory equipment and products. However,
well-conducted studies on the cost-effectiveness of therapeutic drug monitoring for antiepilep-
tic drugs are lacking particularly in patients with structural-metabolic epilepsy. The study
aims to assess the cost-effectiveness of serum level monitoring services in the management
of children with structural-metabolic epilepsy during the first year of diagnosis.
A retrospective cost-effectiveness analysis was conducted from the provider perspective. It
included patients attended a paediatric neurology clinic. The effectiveness measures used in
this analysis were the number of patients that achieved ≥50% reduction in seizure frequency,
and the number of patients with 3-month seizure free. Medical records of the patients were
reviewed for the required information. Medical chart/billing data obtained from the hospital
were collected to estimate the resources used (One Malaysian Ringgit MYR is equivalent to 0.31
USD). The recruited children were followed for one year following their first visit.
The average cost effectiveness ratio for the monitored patients (MYR 2735 per patient that
achieved a ≥50% reduction in seizure frequency) was lower than that for non-monitored patients
(MYR 2921 per patients that achieved a ≥50% reduction in seizure frequency), with incremental
cost-effectiveness ratio of MYR 2357 per one additional patient that achieved a ≥50% reduction
in seizure frequency. The average cost effectiveness ratios for monitored and non-monitored
