Severe maternal morbidity is highly associated with the risk of pregnant woman's death

The number of serious maternal illnesses (SMMs) a pregnant woman has is highly associated with her risk of maternal death, according to a new study by ICES scientists and St. John's Hospital. Michael & apos; s Hospital.

SMM is defined by potentially life-threatening conditions such as entry to ICU, invasive ventilation, and cardiac conditions that occur during pregnancy.

A study published today in Open Network JAMA looked at data from more than 1.9 million births in Ontario hospital and found that the number of SMM conditions was strongly associated with maternal deaths within 42 days of delivery. Researchers found that the number of SMMs was exponentially linked to maternal death.

"Our findings show that some SMMs predict death, and in the light of this, we should focus on preventive SMMs or limit their progress through an early-warning system to reduce maternal mortality," Dr. Joel Ray, lead researcher and researcher at ICES and the Li Ka Shing Knowledge Institute at St. Michael's Hospital.

Researchers found that women with one SMM had a 20 times higher mortality rate than women who did not have SMMs and the risk increased to 102 times the risk with two SMMs and up to 2192 times the risk with six or more SMMs.

Conclusions show that the most common conditions for SMM were bleeding after postpartum blood transfusion bleeding, admission to ICU, puerperal sepsis (bacterial infection), severe preeclampsia (high blood pressure), and an urgent need for hysterectomy.

Scientists identified 181 maternal deaths of 1,953,943 births – a rate of 9.3 per 100,000 births. Of the 181 deaths, 68% of the women who died had at least one SMM disease. The women who died were older, for the first time mothers, with lower income and African-Caribbean origin, with multifetal pregnancy, with pre-existing diabetes, high blood pressure, and kidney disease.

"Despite improvements in family planning and obstetric care, maternity deaths remain stable in Canada, with half of them being considered as preventive." Our findings illustrate the value of using existing maternal early warning systems and protocols to identify a woman's clinical worsening to reduce maternal deaths, "he adds. Ray.

"The prevalence of serious morbidity in the mother and maternal mortality factors in Canadian Ontario" was published today at JAMA Open Network.
