Albumin’s association with ICU readmission and mortality is well-documented, although its utility in clinical decision-making is still debated.[26] Hypoalbuminemia reflects illness severity and has been linked to ICU readmission and mortality, particularly in sepsis.[27] However, its predictive value varies, and it should be regarded as an associative feature in our model rather than a causal determinant of readmission. Here, ALB is linked to Hypoalbuminemia.
