RESUMEN
The Sequential Organ Failure Assessment (SOFA) could function as an effective risk stratification tool in the admission of critically ill patients with COVID-19 and would allow stratification based on a risk assessment. We aimed to examine whether the SOFA score is useful to define 2 severity profiles in COVID-19 patients admitted to ICU: mild with SOFA < 5, and severe with SOFA ≥ 5. A retrospective cohort, multicenter study was conducted from February 11 to May 11, 2020. We analyzed patients admitted to all ICUs of the 14 public hospitals of the Castilla-La Mancha Health Service at the beginning of the pandemic and with SARS-CoV-2 infection. Patients were divided in 2 groups according to the level of severity by SOFA at admission to the ICU. Cox regression was used to evaluate factors associated with survival and Kaplan-Meier test to examine survival probability. In total, 405 patients with a complete SOFA panel were recruited in the 14 participating ICUs. SOFA <5 group showed that age above 60 years and D-dimer above 1000 ng/mL were risk factors associated with lower survival. In SOFA ≥ 5 it was found that high blood pressure was a risk factor associated with shorter survival. Kaplan-Meier showed lower survival in SOFA ≥ 5 in combination with high blood pressure, time since viral symptom onset to admission in ICU < 7 days, D-dimer ≥1000 ng/mL and respiratory pathology. However, SOFA < 5 showed only higher age (≥60 years) associated with lower survival. Age over 60 years and D-dimer over 1000 ng/mL were risk factors reflecting lower survival in patients with SOFA < 5. Moreover, SOFA ≥ 5 patients within a week after COVID-19 onset and comorbidities such as high blood pressure and previous respiratory pathology showed lower survival.
