Effects of a multifaceted intervention to promote the use of intravenous iron sucrose complex instead of ferric carboxymaltose in patients admitted for more than 24 h.

Purpose: Although more practical for use, the impact of ferric carboxymaltose (FCM) on the hospital budget is considerable, and intravenous iron sucrose complex (ISC) represents a cost-saving alternative for the management of iron deficiency anemia in patients during hospitalization. The Drug Committee decided to reserve FCM for day hospitalizations and contraindications to ISC, especially allergy. ISC was available for prescription for all other situations.
Methods: The impact of a multifaceted intervention promoting a switch from FCM to ISC was evaluated using an interrupted time series model with segmented regression analysis. The standardized rate of the dispensing of FCM, ISC, and oral iron by the hospital pharmacy, as well as the rate of the dispensing of packed red blood cells and the number of biological iron status measurements, was analyzed before and after the intervention.
Results: There was an immediate decrease in FCM consumption following the intervention, with a reduction of 88% (RR: 0.12 [CI _95% 0.10 to 0.15]). Conversely, there was a large increase in ISC use (RR: 5.1 [CI _95% 4.4 to 5.9]). We did not observe a prescription shift to packed red blood cells or oral iron after the intervention. The time series analysis showed the frequency of iron status testing to remain stable before and after. The direct savings for intravenous iron for 8 months were 187,417.54 €.
Conclusion: Our intervention to lower the impact of intravenous iron therapy on the hospital budget was effective.
