Organ Dysfunction Assessment

Prognostic Factors

• The Modified SOFA score, assessed after 3 days, is a crucial prognostic factor in cirrhotic patients, with a high predictive value for outcomes, as recommended by the Society of Critical Care Medicine and the American Association for the Study of Liver Diseases 1
• A bedside screening tool evaluating altered mental status, systolic BP ≤100 mmHg, and respiratory rate >22/min can indicate high risk of poor outcomes, with a score ≥2, although it is less discriminative than the full SOFA score (AUC 0.712 vs 0.744) 2
• Persistence of 3-4 non-hematological organ failures at day 3 predicts in-hospital mortality with 93% specificity, according to the American Thoracic Society and the Society of Critical Care Medicine 1
• The evolution of the SOFA score between days 3-7 better predicts 28-day and 90-day mortality than the score at diagnosis (AUROC 0.86 vs 0.65), as suggested by the European Society of Intensive Care Medicine 1

Scoring Systems

• The following scores are used to evaluate organ dysfunction:

• The SOFA score >10 is predictive of mortality in 93% of cases, according to the American Society of Anesthesiologists 1
• The APACHE II scoring system demonstrates excellent discriminative power for mortality prediction with a pooled AUC of 0.81, as recommended by the American College of Critical Care Medicine and the Society of Critical Care Medicine 3
• The SMART-COP scoring system estimates the need for intensive respiratory and vasopressor support by assigning points to 8 clinical features, including systolic BP, multilobar involvement, albumin level, respiratory rate, tachycardia, oxygenation, arterial pH, and BUN, as endorsed by the American College of Chest Physicians 2

Sepsis Definition and Management

• Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection, characterized by an increase in the SOFA score of 2 points or more, as defined by the American College of Radiology and the Society of Critical Care Medicine 4, 5, 6
• The quick Sequential Organ Failure Assessment (qSOFA) is a bedside screening tool that evaluates three clinical parameters: altered mental status, systolic blood pressure ≤100 mmHg, and respiratory rate >22/min, to identify patients at risk of sepsis, with a score ≥2 indicating high risk, and a strength of evidence classified as moderate 4, 5, 7, 8, 9, 10, 6
• High-risk patients (qSOFA ≥2 or NEWS2 ≥7) should receive broad-spectrum antibiotics within 1 hour, IV fluid bolus (30 ml/kg crystalloid) for hypotension, and monitoring every 30 minutes, as recommended by the guideline society, with a strength of evidence classified as high 7, 11

Triage and Resource Allocation

• Regular, repeated scoring enables monitoring of patient condition and disease development, and can help prioritize patients for ICU admission during mass casualty incidents or resource-limited scenarios, supported by the European Society of Intensive Care Medicine and the Society of Critical Care Medicine, with a strength of evidence classified as low 9, 12
• Patients with lower SOFA scores may receive higher priority for limited resources, and the score can be used in triage prioritization tools to determine qualification for ICU admission, as recommended by the European Society of Intensive Care Medicine, with a strength of evidence classified as low 12, 13
• The APACHE score should be calculated within the first 24 hours of ICU admission using the worst values recorded during that period, and used in conjunction with clinical judgment, as recommended by the Society of Critical Care Medicine 14
