Abstract
ALANIS-NARANJO, José Martín; ANGUIANO-ALVAREZ, Víctor Manuel; HAMMEKEN-LARRONDO, Eduardo Federico and OLGUIN-CONTRERAS, Gabriela. Performance of PSI/PORT and SOFA in predicting mechanical invasive ventilation in SARS-CoV-2 pneumonia. Med. crít. (Col. Mex. Med. Crít.) [online]. 2022, vol.36, n.3, pp.155-160. Epub Dec 05, 2022.

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.
