+[[ALERT Scale]] Calculation (go to [[ALERT Scale App]])
-After some searching I don't actually think we have the calculation for the MOST score documented on the wiki. Julie, could you please put it up here? Please include what the meaning of the calculated score is.
-Thanks!

+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 [[Charlson Comorbidity Index]])
+*+(0.0532 x Total [[ADL Score]]
+*-(0.1720 x [[Glasgow Coma Scale | Glasgow Coma Scale (GCS)]])
+*+(0.0678 x [[Age]] in years)
+*-(0.0004 x (age x age)
+*+(0.0175 x heart rate in beats per min )
+*+(0.0631 x respiratory rate in breaths per min )
+*+(0.0289 x white blood cell count in cells per microlitre x 0.001 )
+*-(0.0410 x systolic blood pressure in mm Hg )
+*+(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.
+How to calculate R:
+*'''R=exp(Y)/1 + exp(Y)'''
+*Heart rate ([[HR]]), respiratory rate ([[RR]]), White Blood cell Count ([[WBC]]), systolic Blood Pressure (sBP, [[AP Sys BP Field]]) - are continuous data
+The cut-off probability for '''R''' is 0.088 . "A cut-off point of 0.088, or a predicted probability of adverse outcome of 8.8%, was used to classify patients into two groups; high-risk and low-risk of adverse outcome." ([[Media:Bmjopen-2014-005501.ALERT SCALE.pdf|from publication]])
