Introduction:

There are few publications on the application of prognostic scales to predict the use of invasive mechanical ventilation (IMV) in SARS-CoV-2 pneumonia. Therefore, the study’s objective was to evaluate the performance of PSI/PORT and SOFA in predicting the use of IMV in patients with SARS-CoV-2 pneumonia.

Material and methods:

A retrospective study that included hospitalized patients with SARS-CoV-2 pneumonia from April 01, 2020, to May 31, 2020. Analysis of ROC curves was performed, calculating the area under the curve for PSI/PORT and SOFA scores, as well as sensitivity, specificity, and predictive values.

Results:

151 patients were included, aged 52 years (IQR 45-64); 69.5% were men. Of the total, 102 patients required IMV (67.5%). Area under the curve to predict IMV were: SOFA 0.71 (95% CI 0.64-0.78) and PSI/PORT 0.78 (95% CI 0.71-0.85). When comparing them, there was no statistical significance (p = 0.08).

Conclusions:

In patients with SARS-CoV-2 infection, SOFA and PSI/PORT may underestimate the need for IMV. In our study, SOFA and PSI/PORT score performed fair in predicting IMV use in hospitalized patients with SARS-CoV-2 pneumonia.
