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

value of Z =
= SUM(points for all of the parameters) - 4.665
probability of critical illness =
= 1 / (1+ EXP((-1) * Z))
Performance:
• The area under the ROC curve was 0.82 in the derivation and 0.79 in the validation cohorts.
