Background:
Iron deficiency anaemia is a public health problem. In case oral iron treatment is ineffective, poorly tolerated or contraindicated, the intravenous route becomes the first choice. The aim of the study was to evaluate the shift between ferrous gluconate (FG) and ferric carboxymaltose (FCM) usage at our hospitals over the years. We also performed a cost comparison between pre and post-FCM availability periods, taking into account the acquisition costs of both intravenous iron and red blood cell units (PRBC).
Study Design And Methods:
The amount and costs of FG and FCM released by hospital Pharmacy Services from 2010 to 2019 were analysed, along with the number of transfused PRBC units in the same timeframe.
Results:
Overall, the proportion of FCM usage rose from 8.6 % in 2014 to 71.9 % in 2019, as percentage of total intravenous iron released. After exclusion of haemodialysis, where FG is still widely used, the FCM use in the last four years raised from 12.9% to 92.5%. Despite the higher FCM cost, the mean yearly expenditure for intravenous iron plus PRBC units did not differ between pre- and post-FCM eras (2010-2013, € 2,396,876 € versus 2014-2019, € 2,307,875 - p = 0.234), as a result of a net decrease of PRBC usage, namely from 15,083 to 12,654 (-16.1 %), respectively.
Discussion:
Intravenous iron has a major role in treating iron deficiency anaemia in several settings. Third generation compounds are paving the way to more updated and safer treatments.
