Boisrame et al identified risk factors for placental abruption during pregnancy. A patient at risk for abruption and her fetus may benefit from more aggressive management. The authors are from Strasbourg University Hospital in France.


Risk factors:

(1) parity >= 3 (odds ratio 1.6)

(2) gestational hypertension (odds ratio 7.4)

(3) pre-eclampsia (odds ratio 2.9)

(4) preterm premature rupture of membranes (PPROM, odds ratio 9.5)


The risk for abruption increases with the number of risk factors present.


The cumulative odds ratio (PRODUCT of odds ratios) may indicate the risk assuming that the risk factors are independent.
