Introduction
Intravenous (IV) iron is typically the preferred treatment for patients with iron deficiency anemia (IDA) who cannot tolerate or absorb oral iron, or who require fast replenishment of iron stores pre-operatively. Several IV iron formulations are available with different dosing characteristics affecting infusion speed and maximum dose. The aim was to develop a resource impact model to calculate the cost of establishing an IV iron clinic and model resource impact of different IV irons to inform clinicians and service providers implementing innovative pre-operative IV iron services in Ireland.
Methods
A resource impact tool was developed to model resource utilization and IDA treatment costs. Two fast-administration, high-dose formulations of IV iron are available in Ireland: iron isomaltoside 1000/ferric derisomaltose (IIM) and ferric carboxymaltose (FCM). The tool modeled clinic throughput based on their different dosing characteristics in a specific IDA population, capturing fixed overheads, variable costs, clinic income from private and publicly-funded patients, and savings associated with IV iron.
Results
Based on a 70:30 split between public and private patients in a new pre-operative service with capacity for 12 infusion slots weekly, IIM would facilitate correction of iron deficits in 474 patients annually, resulting in a net annual clinic balance of €42,736 on income of €159,887 and net costs of €117,151. FCM would facilitate treatment of 353 patients, resulting in a net annual clinic balance of €36,327 on income of €116,050 and costs of €79,722, a difference of €6408 and 121 patients treated in favor of using IIM over FCM.
Conclusion
Based on this provider-perspective analysis, IIM would maximize clinic throughput relative to other IV iron formulations, allowing clinicians in Ireland to optimize their current service provision and expenditure, and model the impact of introducing IV iron clinics for pre-operative patients with IDA.
