Financial burden associated with discordance to intravenous iron therapies in US patients with iron deficiency anemia
BACKGROUND: Iron deficiency anemia (IDA) affects approximately 5 million people in the United States and has a significant impact on human health. Intravenous (IV) iron is indicated for treatment of IDA when oral iron is not effective or not tolerated. Several IV iron products are available, including oldergeneration and newer-generation products. Newer agents have certain benefits, including the ability to administer high iron doses in fewer infusions; despite the benefits, some payors require failure on older iron products before use of newer iron products in prior authorization processes. IV iron replacement regimens requiring multiple infusions may lead to patients not receiving recommended IV iron treatment per label; potential costs of this discordance may outweigh the difference in price between the older and newer products. OBJECTIVE: To quantify the burden of discordance to IV iron therapy and associated economic consequences. METHODS: This is a retrospective study using administrative claims data between January 2016 and December 2019 from adult patients who are enrolled in a commercial insurance program with a regional health plan. A course of IV iron therapy is defined as all infusions that occur within 6 weeks of the initial infusion. Discordance to therapy is defined as having received less than 1,000 mg of iron over a course of therapy. RESULTS: There were 24,736 patients included in the study. Baseline demographics were similar between the patients who received older- vs newer-generation products and patients who were concordant vs discordant. Discordance to IV iron therapy overall was 33%. Patients who received newer-generation products were less discordant to therapy (16%) than patients who received older-generation products (55%). In general, patients who received newer-generation products had a lower total cost of care than patients who received older-generation products. CONCLUSIONS: Discordance to the older-generation products was significantly higher than that to the newer-generation products. Patients who were concordant to therapy and on a newer-generation product had the lowest total cost of care, suggesting that overall cost of care is not necessarily proportional to the purchase price of the chosen IV iron replacement therapy. Optimizing concordance to IV iron therapy may lead to lower total cost of care in the IDA population. DISCLOSURES: Magellan Rx Management received funding for this study from Pharmacosmos Therapeutics Inc. AESARA contributed to study design and data analysis. Magellan Rx Management contributed to the study design, data analysis, and interpretation of results. Pharmacosmos Therapeutics Inc. participated in the study design and interpretation of results.
