Abstract

Introduction: Taiwan's National Health Insurance Program approved reimbursement of prophylactic coagulation factor replacement therapy (CFRT) for patients with haemophilia (PWH) in 2014. Aim: To examine 15-year trends and the impact of reimbursement for prophylactic CFRT on its utilization and related medical costs for PWH. Methods: We analysed Taiwan's National Health Insurance Database from 2003 to 2017. We included patients with haemophilia A (PWHA) or B (PWHB) receiving coagulating factor. Female patients were excluded because of small sample size. We analysed annual consumption of CFRT units and medical costs. High proportion of days covered (PDC) with CFRT served as an indicator for prophylactic treatment since it reflects routine use of CFRT. We applied interrupted time series analysis (ITSA) to evaluate the impact of reimbursement for prophylactic CFRT on usage patterns and medical costs. Results: We included 896 male PWHA and 181 male PWHB, with 38.1% and 37.0% aged under 18 years, respectively. By ITSA, we found the trends in coagulation factor consumption and PDC significantly increased after reimbursement for prophylactic CFRT in both PWHA and PWHB (p values for trend change <0.05). The overall medical costs per patient increased with increasing consumption of coagulation factor; however, ITSA revealed non-CFRT cost decreased after reimbursement of prophylactic CFRT for both PWHA and PWHB (p values <.05). Conclusion: Reimbursement for prophylactic CFRT facilitated growth in rates of prophylactic CFRT and increased related costs, but curbed rising non-CFRT costs. These findings provide strong grounds for future cost-effectiveness studies to leverage prophylactic CFRT for its therapeutic benefits.
