Risk Score of Suta et al for Predicting Postpartum Hemorrhage (PPH) Following Cesarean Delivery

Description

Suta et al developed a score for predicting postpartum hemorrhage in a woman undergoing cesarean section. This can identify a woman who may benefit from more aggressive management. The authors are from Vajira Hospital and Navamindradhiraj University in Bangkok.

Patient selection: cesarean section

Outcome: postpartum hemorrhage (PPH)

Parameters:

(1) maternal age

(2) race

(3) parity

(4) placenta praevia

(5) acuity of the cesarean section

(6) fetal body size and birthweight in grams

(7) second stage of labor

Parameter	Finding	Points
age in years	< 35 years	0
	>= 35 years	1
race	Thai	0
	other Asian	2
parity	nullipara	0
	multipara	1
placenta praevia	no	0
	yes	4
acuity of surgery	elective	0
	emergency	1
birth weight	< 2,500 grams	-2
	2,500 to 3,999 grams	0
	>= 4,000 grams	2
second stage of labor	normal	0
	abnormal	3

total score =

= SUM(points for all 7 parameters)

Interpretation:

• minimum score: -2

• maximum score: 14

• A score >= 3 was associated with postpartum hemorrhage.

Performance:

• The sensitivity was 60% with a specificity of 18% (poor).

• The area under the ROC curve is 0.61.
