Maternal perinatal mortality: A pediatric issue


 

Checking on the well-being of mothers is one of the important acknowledged aspects of primary pediatric care. “How are you doing?” directed to the child’s mother has long been considered an appropriate question. The AAP recommends several checks in the Bright Futures Guidelines, including conducting several formal screens for depression and asking about “getting time alone with your partner” as well as other supports.

But I have recently become aware of new data that changes my ideas about what we pediatricians need to be doing as part of our care for children and their families, especially in the first year: Considering the risks to the mother of dying.

Maternal mortality increased by 26.6% from 2000 to 2014 across the United States such that it is higher now than it was for our own mothers. The U.S. now has the highest rates of maternal mortality among high-income nations, especially for Black, American Indian, or Alaska Native women, those of lower socioeconomic status, and those under 18 or over 35 years old.

You may be thinking, well, that is an issue for ob.gyns. Indeed, the most common reasons for maternal death are cardiovascular: hemorrhage, hypertensive disorders, deep vein thrombosis, and stroke, all usually occurring at or in the first week after birth. You may have heard about sudden unexpected heart failure from postpartum cardiomyopathy, although rare (1 in 1,000-4,000), presenting from 1 month pre birth to 5 months post delivery, which is when we may be the main clinicians seeing the mother, not the ob.gyns. This can be easily missed since it presents with shortness of breath and decreased exercise tolerance, fatigue, palpitations, and/or leg swelling. Serious eclampsia may have only symptoms of headache or abdominal pain. All of these may easily be mistaken for lingering pregnancy symptoms. But in higher income countries, such as the U.S., 38% of maternal deaths occur from 8 to 42 days after birth, the period for fatal infections as well as cardiac complications. Elevated risk for all of these causes of mortality include Black race, obesity, tobacco use, congenital heart disease, and being older than 40.

As pediatric providers, we may see mothers along with their infants as newborns in the hospital, at day 2, at 2 weeks, or even at 1-2 months after birth, potentially before their one recommended postnatal obstetric visit at 3-8 weeks. Asking the mother how she is feeling at those times should not just be a social nicety but rather an additional check for serious postnatal complications.

Additional concerns

But wait, it gets worse.

Did you know that the leading cause of maternal death from pregnancy up to 1 year after a birth is homicide?

Maternal perinatal mortality figures have not usually included “perinatal-associated” deaths, a maternal death attributable to a condition that is unaffected by the pregnancy and occurring within 1 year of delivery (that I will cite as perinatal henceforth). While half of maternal deaths occur during pregnancy, another half occur in the year following. There were 3.62 homicides per 100,000 live births among females who were pregnant or within 1 year postpartum, 16% more than for similarly aged nonpregnant and nonpostpartum women (3.12 deaths/100,000 population, P < .05). Homicides made up 8.4% of reported perinatal maternal deaths from all causes, with a rate of 1.7 per 100,000 live births, twice the rate of any one of the other leading causes noted above. Black women had seven times the risk of perinatal homicide as that of White women. Females under 20, many of them our own pediatric patients, had a greater than six times higher risk and those aged 20-24 had a 65% higher risk of pregnancy-associated homicide across race and ethnic groups. Homicide is most likely before 21 weeks of pregnancy, decreases in the third trimester, but increases again after birth. Two-thirds of pregnancy-associated homicide deaths occurred in the home, with the perpetrator a current or prior partner (> 59%, with 98% being male), 45%-50% were associated with reported intimate partner violence (IPV), and the most common method was a firearm (55%). Often the same women had histories of substance abuse, serious mental illness, and/or prior IPV, all risk factors for pregnancy-associated deaths, including from homicide.

Homicide? “Not the mothers in my practice,” you may say, but, if not homicide, drug-related deaths (3.68 per 100,000 person-years) and suicide (1.42 per 100,000 person-years) together comprise 18% of all maternal deaths. Non-Hispanic White women, Medicaid-insured women, and women residing in smaller cities were especially likely to die from drugs or suicide. More than half (54.3%) of perinatal suicides involve intimate partner conflict, which increases the risk ninefold. Perinatal mood disorders, affecting up to 15% of pregnant and postpartum U.S. women, is also a risk factor in substance abuse, opioid overdose death, and suicide.

And substance use has gotten more dangerous with the increase in fentanyl lacing. Pregnancy-associated deaths (4%-10% of deaths) involving opioids more than doubled between 2007 and 2016, and, although the rates are higher for Black women, the increase has been greater for non-Hispanic White women. Two-thirds of those deaths occur between 6 and 12 months postpartum, on our watch. Although many women decrease substance use during pregnancy, they may fall back into substance use (rates increase 4 times by 7-12 months after delivery) and not continue to receive treatment. Although pharmacotherapy (e.g., methadone, buprenorphine treatment) is the current standard of care for opioid use disorder (OUD) during pregnancy, nearly half receiving treatment in publicly funded centers are not receiving these medications and others may lose insurance or access to pregnancy-related treatment programs after delivery, increasing risk of relapse. Stigma, and punitive or discriminatory approaches to pregnant women with OUD (e.g., jail, removal of children) can dissuade them from participating in treatment, increasing overdose risk.

It is important to note that in more than half of the 41 deaths from violent trauma in one study (including 22 homicides), obstetrical providers knew of or suspected IPV. Also, the vast majority (74%) of those who died by drugs or suicide had made one or more emergency department or hospital visit between their delivery and death, and 39% had made three or more visits. Without knowing if anything was done in those cases, we also know that, in addition to thorough, compassionate providers, there is sometimes segmentation of responsibility, insensitivity, discrimination, racism, stigma, inequity, lack of resources, lack of access, lack of payment mechanisms, legal issues for immigrants, time constraints, and other systemic deficits that may hinder effective care for these and subsequent women.
