Lactate enhanced-quick Sequential Organ Failure Assessment 2 (LqSOFA2): A new score for bedside prognostication of patients with sepsis

Background P<0.0001). The mean lactate on days one, three and seven in survivors were 2.27±0.91, 1.72±0.77 and 1.14±0.48, respectively, while it was 4.32±2.35, 3.57±2.28 and 2.13±1.22, respectively, in the non-survivor group (P<0.001). The new score LqSOFA2 also significantly predicted mortality between non survivors and survivors (3.52±0.71 vs. 2.37±0.91). There was a significant correlation of qSOFA with SOFA and APACHE II on day one. Lactate levels and SOFA correlated on all three days. Interpretation & conclusions: qSOFA, a novel score and lactate can independently predict mortality in patients with sepsis. They correlate with APACHE II and SOFA but fail to equilibrate with either. The combination score LqSOFA2 showed marginal (statistically insignificant) increase in predictive accuracy and specificity when compared to lactate or qSOFA alone. Early diagnosis by LqSOFA2 makes it a good standalone bedside prognostic marker.
