Wang et al reported a nomogram for predicting enteral feeding intolerance for a critically ill patient. The authors are from Jilin University in Changchun, China.
Patient selection: ICU patient on enteral nutrition
Parameters:
(1) primary diagnosis
(2) acute gastrointestinal injury (AGI) grade from 1 to 4
(3) APACHE II score from 0 to 40
points for APACHE II =
= 2.04 * (APACHE)

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 215
value of X =
= (0.0478 * (score)) - 3.961
probability of enteral feeding intolerance =
= 1 / (1 + EXP((-1) * X))
Performance:
• The area under the ROC curve is 0.85 for the derivation and 0.88 for the validation cohorts.
