Description
Ziang Li and colleagues build a simple ratio score for death risk in septic shock in a 2026 study. Lactate alone can understate risk when its rise is modest, so lactate was paired with diastolic pressure into one ratio. Past records from two intensive care groups were used to build and test the score.
The build group held 320 patients and the test group held 962 patients from a large database. Death at 28 days neared three in ten in both groups. The ratio sorted risk in both groups and beat lactate alone by a small margin. Gains in the gray zone were modest, so the score should aid, not replace, lactate.
