Anemia is a common and multifactorial condition encountered in critically ill patients, with potential consequences such as impaired oxygen delivery, increased cardiac workload, delayed wound healing, and worsened clinical outcomes. In the ICU, anemia often arises from acute blood loss, inflammation, impaired erythropoiesis, frequent phlebotomy, or nutritional deficiencies, making its evaluation and management a critical component of patient care. Understanding the complex interplay of these factors is essential for optimizing patient outcomes both during critical illness and after ICU discharge [1, 2] [Ref: Algorithm 91.1].
