Severe maternal morbidity in Canada, 1991-2001

The death of a mother during pregnancy or delivery is fortunately a rare event. So rare, that routine tracking of national and provincial rates, while important, fails to capture other non-fatal but serious health hazards.

Shi Wu Wen and colleagues report rates of severe maternal morbidity in Canada over a 10-year period. Severe maternal morbidity, such as cardiac arrest, postpartum hemorrhage requiring transfusion, uterine rupture and other life-threatening illnesses occur in 1 of every 250 deliveries. Women who developed these complications were 158 times more likely to die than women who did not have the complications. An analysis over the 10-year period of the study showed that rates for some complications, such as hemorrhage requiring transfusion, were declining, while others, such as uterine rupture, were increasing.

There is a worldwide trend towards improved monitoring of maternal health during pregnancy and in the postpartum period.
