MOST Score Calculation

Binary logistic regression resulted in the following outcome model:

  • LN(R/1-R) = Y

Y =

  • -3.8390 + (0.1570 x male gender)
  • +(0.0712 x CCI)
  • +(0.0532 x ADLS)
  • -(0.1720 x GCS)
  • +(0.0678 x age)
  • -(0.0004 x (age x age)
  • +(0.0175 x heart rate)
  • +(0.0631 x respiratory rate)
  • +(0.0289 x white blood cell count)
  • -(0.0410 x systolic blood pressure)
  • +(0.000121 x (systolic blood pressure x systolic blood pressure)

Where R is the risk of bad outcome and the categorical variable gender, is coded female=0 and male=1.

  • CCI - Charlson Comorbidity Index
  • ADLS - Activity of Daily Living Score:
    • 0 - independent
    • 3 - minor dependence
    • 6 - major dependence
  • GCS - Glasgow Coma Scale]]
  • Heart Rate (HR), Respiratory Rate (RR), White Blood cell Count (WBC), systolic Blood Pressure (sBP) - are continuous data


How to calculate R:

  • R=exp(Y)/1 + exp(Y)


The cut-off probability for R is 0.088
