ABSTRACT

Objective: To compare the qSOFA and qCSI scales to predict severity and mortality in patients with COVID-19.
Materials and Methods: Observational, cross-sectional study of patients hospitalized at the High Specialty Medical Unit No. 71, Torreon, Coahuila, Mexico, for SARS-CoV-2 infection confirmed by RT-PCR, from October to November 2020. Demographic variables, comorbidities, severity of COVID-19 disease, qSOFA and qCSI scales, need for invasive mechanical ventilation, ICU admission, length of hospital stay and mortality were assessed.
Results: A total of 166 hospitalized patients (99 women and 67 men; mean age 60 years) were analyzed. The severity of the disease was classified as moderate (3.6%), severe (92.2%) and critical (4.2%) according to the WHO. The qSOFA scale to predict mortality was not discriminant, with an area under the curve of 0.524; sensitivity: 59%, specificity: 51%. While the qCSI scale for severity prediction had an area under the curve of 0.651; sensitivity: 97%, specificity: 29%, and for mortality prediction it had an area under the curve of 0.735; sensitivity: 95%, specificity: 52%.
Conclusions: Statistically significant results were obtained with the qCSI scale with a score ≥ 5 to predict severity and ≥ 7 to predict mortality. These scoring systems could help clinicians design specific interventions to try to decrease mortality in Mexican patients with COVID-19.
