Score of Fuchs et al for Predicting Early Preterm Birth in a Singleton Pregnancy

Description

Fuchs et al developed a simple score for predicting the chances of an early preterm birth in a woman with a singleton pregnancy. This can help the physician and woman to decide about the need for emergency cerclage. The authors are from multiple hospitals in France.

Patient selection: woman with a singleton pregnancy

Parameters:

(1) obstetric history

(2) cervical dilation in cm

(3) status of membranes

(4) evidence of infection (WBC count >= 13,600 per µL or CRP > 15 mg/L)

Parameter	Finding	Points
obstetric history	primigravida	4
	multigravida, no history of second trimester pregnancy loss	0
	multigravida, history of second trimester pregnancy loss	5
cervical dilatation in cm	1 cm	0
	2 cm	1
	3 cm	2
	>= 4 cm	4
membranes	visible at external os	0
	bulging through os into vagina	4
evidence of infection	none	0
	present	2

total score =

= SUM(points for all 4 parameters)

Interpretation:

• minimum score: 0

• maximum score: 15

• The higher the score the greater the chances of early preterm birth.

probability of early preterm birth =

= 1 / (1 + EXP((-1) * ((0.382 * (score)) – 2.363)))
