Muhammet Özbilen: Is the IV Iron Given to Hospitalized Patients Sufficient?

Muhammet Özbilen, Associate Professor Doctor at Ordu University, shared a post on LinkedIn about a recent article by Joséphine A. Cool et al. published in AJH, adding:

“Is the IV iron given to hospitalized patients sufficient?

A paper published last month in the American Journal of Hematology paints a vivid picture.

The investigation was carried out at Harvard Medical School’s training hospital.

  • More than 200,000 hospital admissions from 5 years were studied.
  • Only 31.5% of anemic individuals had their iron levels checked.
  • Only half (54%) of patients with iron deficiency anemia (IDA) were given iron supplements.
  • The calculated median iron deficiency in patients receiving IV iron was 1,847 mg, while the median amount provided was only 500 mg.

So ‘Mind the Gap’ expresses just this: there is a 1,364 mg difference in the IV iron dose provided.

The cause for this big disparity can be described as follows:

  • Iron measurements are commonly neglected when anemia is not the main reason for admission.
  • The majority of DEA patients in this investigation were normocytic (median MCV: 86), contrary to expectations of microcytosis.
  • Ferric gluconate is the most often used IV iron formulation with a low daily maximum dose. However, it is insufficient for non-dialysis patients and requires numerous doses.
  • The present hospital treatment approach prioritizes acute stabilization over chronic disease management.

However, appropriate iron therapy has been shown to normalize hemoglobin levels within 8 weeks, reducing the need for outpatient IV iron.

Conclusion: DEA is underdiagnosed and undertreated in the inpatient context. To address this, physician education and system-level interventions are required.”
