Simplified Fournier Gangrene Severity Index Score (SFGSI)

Description

Lin et al validated the original Fournier Gangrene Severity Index (FGSI) for patients with Fournier gangrene. They identified a subset of the original parameters that can predict mortality. The authors are from National Cheng Kung University in Taiwan.

Patient selection: Fournier gangrene

Parameters:

(1) serum potassium in mmol/L

(2) serum creatinine in mg/dL

(3) hematocrit in percent

Parameter	Finding	Points
serum potassium in mmol/L	>= 7.0	+4
	6.0 - 6.9	+3
	5.5 - 5.9	+1
	3.5 - 5.4	0
	3.0 - 3.4	+1
	2.5 - 2.9	+2
	< 2.5	+4
serum creatinine in mg/dL	> 3.5	+4
	2- 3.4	+3
	1.5- 1.9	+2
	0.6- 1.4	0
	< 0.6	+2
hematocrit in percent	>= 60	+4
	50- 59.9	+2
	46- 49.9	+1
	30- 45.9	0
	20- 29.9	+2
	< 20	+4

Fournier's gangrene severity index score =

= SUM (values for parameters)

Interpretation:

• minimum score: 0

• maximum score: 12

• A score > 2 has a sensitivity of 87% and specificity of 77% for mortality.
