ABSTRACT
INTRODUCTION:
Adverse skin reactions due to drugs such as Stevens Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) occur in 3% of people receiving anti epileptic drugs (AED). Although SJS/TEN has a low incidence, the mortality and morbidity rates are high. Indonesia has not adopted HLA-B*1502 screening prior to administration of carbamazepine (CBZ), although previous studies found a relationship between HLA-B*1502 and SJS/TEN.METHODS:
A hybrid decision tree and Markov model was developed to evaluate three strategies for treating newly diagnosed focal epilepsy CBZ direct therapy, levetiracetam (LEV) direct therapy, and therapy based on HLA-B*1502 test results. From a societal perspective, base case and sensitivity analyses were carried out over a lifetime.RESULTS:
Direct administration of CBZ appears to have a slightly lower average cost than the HLA-B*1502 allele screening strategy. The increase in quality-adjusted life year (QALY) in HLA-B*1502 screening before treatment related to the cost difference reached 0.519 with an incremental cost-effectiveness ratio (ICER) of around USD 984 per unit of QALY acquisition. Direct treatment of LEV increased treatment costs by almost USD 2000 on average compared to the standard CBZ strategy. The increase in QALY is 0.834 in direct levetiracetam treatment, with an ICER of around USD 2230 for each QALY processing.CONCLUSION:
Calculation of the cost-effectiveness of lifetime epilepsy therapy in this study found that the initial screening strategy with the HLA-B*1502 test was the most cost-effective.Key words
