Iron deficiency anemia--bridging the knowledge and practice gap

Area of Science:

• Hematology
• Internal Medicine
• Clinical Practice

Background:

• Anemia is highly prevalent across patient populations, particularly in hospitalized individuals.
• Anemia is linked to adverse clinical outcomes, including increased hospital stay, reduced quality of life, and higher morbidity/mortality.
• Anemia is a modifiable risk factor for allogeneic blood transfusions, carrying its own risks.

Purpose of the Study:

• To provide recommendations for the detection, diagnosis, and management of anemia.
• To address the unmet medical need in identifying and treating iron deficiency anemia and iron-restricted erythropoiesis.
• To review current evidence on anemia prevalence, etiology, health implications, and therapeutic options.

Main Methods:

• A multidisciplinary panel of anemia management experts convened.
• Reviewed published data on anemia prevalence, etiology, health implications, and management guidelines.
• Developed an algorithm for anemia detection and management.

Main Results:

• Iron deficiency is frequently observed in anemic patients.
• The proposed algorithm incorporates iron studies (transferrin saturation), renal function tests (serum creatinine, glomerular filtration rate), and vitamin B12/folic acid levels.
• Management strategies include iron therapy (oral/IV), erythropoiesis-stimulating agents, and appropriate referrals.

Conclusions:

• Anemia requires greater clinical attention due to its high prevalence and negative impact on patient outcomes.
• A systematic approach to anemia detection and management, including iron status assessment, is essential.
• Effective management strategies can mitigate the adverse effects of anemia and reduce transfusion needs.
