The main therapy of β-thalassemia major are blood transfusion and iron chelation drugs. However, those therapies also have some adverse effects and problems such as iron overload, transfusion reactions, nutritional deficiencies, and patient compliance problems. Those arising problems also have an impact on therapy cost. Hence, this study was designed to analyze drug utilization study and cost of therapy in β-thalassemia major adult patients at Dr. Soetomo General Hospital Surabaya. This research was conducted in descriptive observational-retrospective design using secondary data obtained from patient's medical records and billing registrations from January 1-December 31, 2019. There were 18 patients out of 233 patients that were analyzed. Deferasirox was the most administered drug with doses between 500 mg/day-1,500 mg/day while deferiprone was ranged between 1,500 and 4,500 mg/day. Patients also received transfusion reaction drugs with dexamethasone injection 5 mg/ml which was administered the most. The most administered supplement was folic acid 1 mg. Patients had an increase in serum ferritin due to low compliance. Deferasirox had the most adherence number of patients with decrease of serum ferritin. The two highest costs of direct medical components were top-up medicines and consumable medical supplies. Overall, the hospital gained profit from national health insurance claims. The most administered chelating agent was deferasirox. Deferasirox also had the most adherence number of patients with decreased number of serum ferritin. However, deferasirox also yielded the highest cost. Yet, overall, the hospital gained profit from national health insurance claims.
