Area of Science:

• Hematology
• Internal Medicine

Background:

• Anemia is a highly prevalent condition across various medical and surgical specialties.
• Effective management of anemia is crucial due to its significant clinical impact.

Purpose of the Study:

• To review the epidemiological characteristics of anemia.
• To discuss the clinical evaluation and therapeutic options for anemia.
• To emphasize anemia management in critically ill patients.

Main Methods:

• This is a review article.
• It synthesizes current knowledge on anemia epidemiology, evaluation, and treatment.
• Focuses on evidence-based therapeutic strategies.

Main Results:

• Anemia presents diverse epidemiological features.
• Clinical evaluation involves assessing its impact and causes.
• Therapeutic strategies include blood transfusions, erythropoiesis-stimulating agents, and iron therapy.

Conclusions:

• Rational use of anemia treatments, guided by clinical evidence, is essential.
• Alternative therapies to allogeneic blood transfusion should be considered.
• Optimizing anemia management, particularly in critically ill patients, is a key clinical responsibility.
