Description

He et al reported a nomogram for predicting severe pneumonia in a pediatric patient with adenoviral pneumonia. This can help to identify a patient who may require more aggressive management. The authors are from Hunan Normal University in Changsha, China.


Patient selection: pediatric patient with adenoviral pneumonia

 

Parameters:

(1) gender of the patient

(2) serum LDH in IU/L

(3) pulmonary emphysema

(4) lung consolidation score in lung CT images, from 0 to 9

(5) lobular inflammation score in lung CT, from 0 to 16

 

points for serum LDH =

= 0.02857 * (LDH)

 

points for consolidation score =

= 4.733 * (score)

 

points for lobular inflammation score =

= 1.4587 * (score)

Interpretation:

• minimum score: 0

• maximum score: 206.7

 

value of X =

risk of severe pneumonia=

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

 

Performance:

• The area under the ROC curve is 0.91 in the training and 0.85 in the validation cohorts.
