Mortality Prediction Model of Efstathiou et al for Diabetic Ketoacidosis

Description

Efstathiou et al identified predictors for mortality in a patient with diabetic ketoacidosis (DKA). This can help to identify a patient who may benefit from more aggressive management. The authors are from the University of Athens and Sotiria General Hospital.

Patient selection: diabetic ketoacidosis

Parameter:

(1) severe co-existing disease at presentation

(2) pH at presentation

(3) regular insulin dose in IU during first 12 hours

(4) serum glucose in mmol/L after 12 hours

(5) mental status after 24 hours

(6) fever after 24 hours

Parameter	Finding	Points 1	Points 2
co-existing disease	absent	0	0
	present	1	6
pH	>= 7.0	0	0
	< 7.0	1	4
regular insulin	<= 50 IU	0	0
	> 50 IU	1	4
serum glucose	<= 16.7 mmol/L	0	0
	> 16.7 mmol/L	1	4
mental status	normal	0	0
	depressed	1	4
fever	absent	0	0
	present	1	3

total tally score =

= SUM(points 1 for all 6 parameters)

total points score =

= SUM(points 2 for all 6 parameters)

Interpretation:

• minimum scores: 0

• maximum tally score: 6

• maximum points score: 25

• The higher the score the greater the mortality.

Tally Score	Mortality
0 to 2	0%
3	2%
4	21%
5	88%
6	100%

Total Points Score	Mortality
0 to 14	1%
15 to 18	21%
19 to 25	93%
