Impact of Admission SOFA Score and 48-hour Delta SOFA on Clinical Outcomes in Critically Ill Patients

Organ dysfunctions are associated with high morbidity and mortality. The SOFA (Sequential Organ Failure Assessment) score developed by Vincent et al. sequentially assesses the presence and severity of dysfunctions in six organ systems: respiratory, cardiovascular, coagulation, hepatic, neurological and renal. Although the SOFA score was created to quantify organ dysfunctions, the obvious relationship between organ dysfunctions and mortality has been widely documented. Dynamic measurements of the SOFA score assess response to treatment and can be used to search for perpetuating sources of severity and reassess the treatment plan.

The primary objective of this study will be to assess the impact of an admission SOFA score equal to or greater than 2 and subsequent interventions on outcomes related to the 48-hour delta SOFA on ICU and hospital mortality, length of stay in the ICU, duration of mechanical ventilation, time of vasoactive drug use.

Patients will be divided into three groups: those who did not trigger the SOFA trigger on admission to the ICU (Group 1), those who triggered the SOFA trigger and improved on the third day (Group 2) and, finally, those who triggered the SOFA trigger and worsened on the third day (Group 3).
