Scoring systems for ICU and surgical patients:

MSSS (Meningococcal Septic Shock Score) 


Variables (help)

Values (1 if yes, 0 if no)

Beta

Points

Refractory hypotension

Base deficit > 10 mmol/L

Glasgow coma scale < 8

.

Leukocytes < 4000 / mm3

.

PTT > 150 % control

.

Cyanosis

.

Oliguria

.


(worst value during the first 2 h in the PICU is taken in account)

Predicted Death Rate:
Logit = -5.623+ Sum (values*beta)
Predicted Death Rate =
e(Logit) / (1 + e(Logit))

Score:
Score = Sum (points)

Risk groups:
L ow risk (score <=3) : Mortality rate 3%
Intermediate risk (score 4-5) : Mortality rate 26%
High risk (score >=6) : Mortality rate 74%

Reference

Alpha value (-5.623) has not been still published (with courtesy of Alvaro Castellanos-Ortega).
