Description

Lin et al reported a nomogram for predicting acute respiratory distress syndrome (ARDS) occurring in a patient with adenoviral pneumonia. This can help to identify a patient who may benefit from more aggressive management. The authors are from Central South University, Xiangya Hospital, Zhushou Central Hospital and affiliated laboratories in Changsha, China.


Patient selection: adenoviral pneumonia, immunocompetent, adult from 25 to 55 years

 

Parameters:

(1) dyspnea

(2) SOFA score from 0 to 20

(3) serum LDH in IU/L from 0 to 3,500

(4) ventilatory support

 

points for SOFA =

= 5 * (SOFA score)

 

points for serum LDH =

= 0.0239 * (LDH)

total score =

= SUM(points for all of the parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 231.8

 

value of X =

= (0.0625 * (score)) - 3.932

 

probability of ARDS =

= 1 / (1 + EXP((-1) * X))

 

Performance:

• The area under the ROC curve is 0.90.
