Nevertheless, there is no a specific economic evaluation that has been applied to investigate the cost-effectiveness of FF-FA and FG-MV.Objective: This study aimed to investigate the cost-effectiveness of FF-FA and FG-MV to be implemented in Teluk Bintuni, as one of the districts with the highest prevalence of iron deficiency anemia in Papua by taking the healthcare perspective into account.Methods: A prospective observational study was applied by considering two groups of women (15– 49 years old) with iron deficiency anemia who received FF-FA and FG-MV from September to November 2018. Applying a purposive sampling method, respondents were selected from 875 targeted women in six sub-districts, who met inclusion criteria. To estimate the total cost, we applied a healthcare perspective that considered direct medical cost only (eg, the procurement cost of iron tablets, cost of Hb test, and cost of healthcare visit). To estimate the effectiveness of intervention, we applied two major parameters, such as Hb level and utility score in quality-adjusted life year (QALY). The cost-effectiveness values were evaluated by using the criteria on the cost-effectiveness of healthcare intervention according to the threshold of gross domestic product (GDP) per capita (cost per QALY gained).Results: From 875 targeted women in six sub-districts who met inclusion criteria, we found approximately 222 women with moderate–severe iron deficiency anemia and 110 women with complete data in the group of FF-FA (n=69) and FG-MV (n-41). The results showed that there were significant differences (p-value 2.00 g/dL, $79.93 per patient with Hb increment > 1.00 g/dL, and $11.59 per QALY gained.Conclusion: The ICER was estimated to be $11.59 per QALY gained, which was highly cost-effective, according to GDP-based cost-effectiveness threshold. In addition, the utility score of women with iron deficiency anemia was considered to be the most influential factor impacting the cost-effectiveness value.Keywords: ICER, cost per controlled patient, cost per patient with Hb increment > 2.00 g/dL, cost per patient with Hb increment > 1.00 g/dL, cost per QALY gained
