Model of Prohl et al for Never Regaining Consciousness After Cardiac Arrest

Description

Prohl et al evaluated different outcomes following cardiac arrest. They developed model for predicting the probability of never regaining consciousness after losing consciousness during a cardiac arrest. The authors are from the University of Hamburg and Hamburg-Eppendorf University.


 

Parameters:

(1) age in years

(2) serum NSE (neuron specific enolase) in ng/mL on day 4 (method ECLIA Roche/Hitachi Modular Analytics E170; upper limit of normal reference range at 95th percentile 15.2 ng/mL)

(3) clinical examination score on day 4, which ranges from 0 to 32 (with 32 normal)

 

X =

= (0.061 * (age in years)) + (0.248 * (serum NSE on day 4)) - (0.347 * (CES on day 4)) - 0.73

 

probability of never regaining consciousness =

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