Description

Martinez-Lacalzada et al reported the PRIORITY score for predicting critical illness in a patient with COVID-19. This can help to identify a patient who may benefit from more aggressive management. The authors are from multiple institutions in Spain and members of the SEMI-COVID-19 Network.


Patient selection: COVID-19

 

Parameters:

(1) age in years

(2) moderate or severe dependency

(3) cardiovascular disease

(4) severe chronic kidney disease

(5) dyspnea

(6) systolic blood pressure in mm Hg

(7) tachypnea (> 20 breaths per minute)

(8) SpO2 in percent

(9) oxygen requirement

(10) confusion

Performance:

• The area under the ROC curve was 0.82 in the derivation and 0.79 in the validation cohorts.
