Model of Dubsky et al for Predicting Recurrence of a Diabetic Foot Ulcer

Description

Dubsky et al developed a logistic regression model for recurrence of a diabetic foot ulcer. This can help to identify a patient who may benefit from more aggressive management. The authors are from Institute for Clinical and Experimental Medicine in Prague, University Hospital Maastricht and University of Washington Seattle.

Patient selection: diabetic foot ulcer at initial presentation

Outcome: recurrence within 3 years

Parameters:

(1) location of ulcer

(2) osteomyelitis

(3) hemoglobin A1c in percent

(4) C-reactive protein (CRP) in mg/L

Parameter	Finding	Points
location of ulcer	plantar	2.15
	other	0
osteomyelitis	no	0
	yes	1.64
hemoglobin A1c	<= 7.5%	0
	> 7.5%	1.4
CRP	<= 5 mg/L	0
	> 5 mg/L	1.45

X =

= SUM(points for the 4 parameters) - 3

probability of diabetic foot ulcer recurrence =

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