Abstract

Background: Economic evaluation of subcutaneous immunoglobulin therapy (SCIG) is important, and it has recently been used for treatment of patients with primary immunodeficiency (PID) diseases, and can improve allocation of resources in health care systems. The present research aimed at providing an economic assessment of SCIG and IVIG (intravenous immunoglobulin therapy) administration in Iran. Methods: Data related to clinical effectiveness were obtained from a meta-analysis. Economic analysis was performed taking into account the perspective of health care providers. Incremental cost-effectiveness ratio (ICER) was applied for economic evaluation of the 2 methods, and GDP per capita was considered as a threshold. Results: The results of meta-analysis suggested a higher effectiveness of SCIG compared to IVIG in serum immunoglobulin (Ig) levels (SMD= 0.336) and adverse effects (OR= 0.497), while the cost of IVIG was higher than SCIG ($1370 vs. $121). The ICER obtained in this paper ($2939 for adverse effects and $4348 for serum Ig level) was less than the GDP per capita in Iran ($4,916.10), and thus SCIG is a more cost-effective therapy for PID patients. Conclusion: Switching from IVIG to SCIG is cost-effective for PID patients and is approved by the health care providers' points of view in this study. © 2017, Iran University of Medical Sciences.
