Description

Rocco et al developed an equation using logistic regression to predict mortality in patients with the Adult Respiratory Distress Syndrome (ARDS) following trauma or surgery. This used parameters known at the onset of the ARDS and can be used to identify patients at increased risk for death. The authors are from Brown University in Providence, Rhode Island.


Parameters (see Table 6, page 419):

(1) age of the patient

(2) Lung Injury Score (LIS)

(3) Multiple Organ Dysfunction Score (MODS)

 

L =

= (-1.712) + (2.061 if age > 75) + (1.527 if MODS >= 8) + (0.91 if LIS 2.76 to 3.0) + (1.742 if LIS > 3.0)

 

probability of death =

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