Logistic Organ Dysfunction Score (LODS)
Logistic Organ Dysfunction score for ICU patients: 6 organ systems (neurologic, cardiovascular, renal, pulmonary, haematologic, hepatic), worst values in the first 24 hours of ICU admission, each organ scored by its most severe variable. Total 0–22; converts to predicted hospital mortality.
Score interpretation
Le Gall 1996 conversion: 3.2 % at 0 rising to 15 % at 4.
→ Standard ICU monitoring; organ support as clinically indicated; daily reassessment; target organ function recovery
Le Gall 1996 conversion: 21 % at 5 rising to 59 % at 9.
→ Active organ support (vasopressors, renal replacement, ventilation as needed); daily SOFA/LODS reassessment; ICU consultant review; family communication about prognosis; consider specialist input (renal, hepatology)
Le Gall 1996 conversion: 68 % at 10, 83 % at 12, 96 % at 16, over 99 % at 22.
→ Full ICU organ support; senior ICU consultant involvement; goals of care discussion with family; consider withdrawal of treatment discussions if irreversible; palliative care team involvement; ethical review if prolonged futile treatment
