Popis: International audience; BACKGROUND: The Systemic Inflammatory Response Syndrome (SIRS) and Sequential Organ Failure Assessment (SOFA) scores are widely used as prognostic markers in critical care settings and could improve triage of high-risk paracetamol (acetaminophen) overdose patients. AIM: To evaluate the prognostic accuracy of the SIRS and SOFA scores following single time point paracetamol overdose. METHODS Analysis of 100 single time-point paracetamol overdoses admitted to a tertiary liver centre, with subsequent prospective validation of identified thresholds. Individual laboratory samples were correlated with the corresponding clinical parameters in relation to time post-overdose, and the daily SOFA and SIRS scores calculated. RESULTS A total of 74 (74%) patients developed the SIRS, which occurred significantly earlier in patients who died (n=21) compared with spontaneous survivors (n=53, p=0.05). The SIRS occurred in 70 (70%) patients by 96 hours post-overdose, with a 30% mortality rate; compared with 0% mortality in the 30 non-SIRS patients (p=0.001). Median SOFA scores were significantly higher in non-survivors at 48 (p=0.009), 72 (p7 during the first 96 hours post-overdose predicted death/transplantation with a sensitivity of 95.0 (95% CI 78.5-99.1) and specificity of 70.5 (95% CI 66.3-71.6). A validation cohort of 38 single time-point paracetamol overdoses confirmed the extremely high negative predictive value of both the SIRS and SOFA thresholds. CONCLUSIONS The absence of either a SOFA score >7 or a SIRS response during the first 96 hours following paracetamol overdose could improve triage and reduce transfers of lower risk patients to tertiary liver centres.
