Description
Feng Xu, Jinjiang Li, Wei Zhao, Shijing Ding, and Jing Cao show that tracking a nutrition score over time predicts sepsis death better than one reading at admission. Their 2026 study follows 492 adults with sepsis. The score joins blood protein and immune cell counts into one index.
Admission scores alone split survival weakly and lose force after adjustment. Repeated scores from the first week tell a stronger story. In time-aware models, higher moving scores link to lower 28-day death risk. The two parts of the score, taken alone, show no such link. Joint models that handle early death or discharge confirm the tie. The authors advise watching the trend, not the snapshot, when judging nutrition-linked risk.
