I'll give it a shot by quoting verbatim from the article. To be perfectly fair though, the article is very information dense and has a lot of supporting links as evidence: it's a worthwhile read in my opinion especially if this topic is important to you.

>> Overall summary (last paragraph before the first subtitle)

Through the course of reporting this story, it quickly became apparent that there is no single reason, but instead a complex brew of factors that, together, point to deep-rooted, systemic problems that run through the entire social and health care system of the country. Gender, class, race—and across all, a fragmented, mainly private health system—conspire to work against maternal health.

>> Older, fatter, sicker: The fault of the mothers (first subtitle)

In certain parts of the world—Scandinavia and Western Europe, in particular—a focus on more dedicated care, before, during, and after birth leads to dramatically different results.

Instead, we need to understand why American women are fatter and sicker in the first place, and why manageable conditions end in women dying.

>> Priority matters (second subtitle)

When it comes to pregnant women, this manifests itself in a focus on the child, at the cost of a focus on the mother, as highlighted in a recent investigation by NPR and ProPublica into the issue.

American women typically have three to five ultrasounds of their fetus, for instance, compared to the two or three British (and most other European) women have.

Many other countries (including the UK) provide support from nurses and doulas after a woman has left the hospital, while that’s rarer in the US. Meanwhile, the US is the only rich country that doesn’t mandate maternity leave.

This marked a big step forward given that suicide is the second leading cause of death among postpartum mothers. But a pregnant or postpartum woman who finds herself in need of mental health support still has to navigate a complex process of getting treatment, including waiting lists and screenings, said Joy Burkhard, who leads 2020 Mom, an organization focused on improving maternal mental health care in the US.

Once the baby is born, new mothers in the US generally have to wait six weeks for their first post-delivery obstetrician-gynecologist (OB-GYN) appointment, so even if their doctor is trained to recognize symptoms of depression (which isn’t common) those first symptoms of depression that can follow delivery will be missed entirely. This contributes to a vast underdiagnosis of postpartum depression (only 50% cases are recognized in the US) and undertreatment of the condition (15% receive treatment). Suicide accounts for 20% of postpartum deaths.

According to the CDC, as many as 17% of the pregnancy-related deaths caused by blood clots—like Liz Logelin’s—could be prevented with simple measures such as compression stockings, or anti-coagulants post-surgery. Such precautions are typically employed after other kinds of surgery, yet often aren’t after c-sections. It was only in 2011 that the American College of Obstetricians and Gynecologists (ACOG) postpartum guidelines were updated to recommend anticoagulant therapies following a c-section.

>> Birthing while black (third subtitle)

But 10 days past her due date, even though neither she nor the baby showed any signs of distress, the personnel at the hospital insisted on inducing labor.

Maddy Oden, her mother, remembers her daughter arguing with the staff that she did not want to be induced, but “finally the nurse said ‘well, you don’t want to go home with a dead baby, do you?’” This succeeded in gaining her daughter’s assent.

She said it was only later, after both Tatia and baby Zorah had died during an emergency c-section, that the family was told that the drug, misoprostol, could cause severe side effects, including amniotic fluid embolism, a potentially lethal complication of childbirth that occurs when amniotic fluid enters the bloodstream.

>> A matter of access (fourth subtitle)

“Maternal health doesn’t just begin [and end] at pregnancy,” says Nadia Hussein, an advocate with MomsRising, noting that health care before, in between and after pregnancies is equally important, especially for the 20% of women dependent on Medicaid who suffer from chronic conditions like depression, hypertension, and type 2 diabetes.

For example, of the 3,144 counties that make up the US, more than a third—1,263—don’t have an OB-GYN. By 2020, it is estimated the country will be 8,000 to 9,000 OB-GYNs short, largely because the number of OB-GYNs has remained steady since the 1980s, while the population has continued to grow. Financial pressures are, once again, a major reason why. OB-GYNs pay the second-highest malpractice insurance rates after neurosurgeons, reflecting their exposure to a high risk of claims against them. (78% of ACOG fellows have been sued at least once in their career.)

Crear-Perry describes the hospital birthing practice as a mix of “efficiency and fear of litigation.” There are, she says, certain delivering techniques, for instance how to turn a baby who’s in an inconvenient position for birth, that are no longer taught to OB-GYNs. They are instead trained to turn to surgical intervention whenever the situation isn’t straightforward, or if delivery isn’t happening within a certain timeframe.

>> Too much is not enough (fifth subtitle)

C-sections, after all, are far more convenient for a hospital. They are easier to schedule, quicker, and make a lot more money; a US hospital can, on average, bill 50% more for a c-section than a vaginal delivery.

Jennie Joseph, a British-trained nurse midwife who has been practicing in the US for the past 26 years and runs Commonsense Childbirth, a birth center which offers midwifery prenatal care in Orlando, Florida, sums it all up effectively: “It’s racism, it’s classism, it’s sexism: All of these things are at play and […] the intersection with capitalism and power,” she told Quartz. “[Women] are dying of a system that’s broken.”

>> No country for new mothers (sixth subtitle)

If the US was like other rich countries, a health crisis such as this would be met with a flurry of initiatives, spearheaded and mandated at a federal level, to find out why mothers are dying, and to figure out ways to reverse it. But the US isn’t like other rich countries. With its uniquely fragmented health system, straddling states and federal government in a complex web of public and private, for-profit and nonprofit, it is nearly impossible to effectively tackle complex issues.

For years, 27 state review groups known as maternal mortality review committees (MMRCs)—some which have sprung from public-health initiatives, others via state OB-GYN societies—have tried to look at available data to assess the causes of maternal death, and if and how they were preventable.

Five years ago, the CDC embarked on an effort to coordinate this ad-hoc system of state-by-state analysis of maternal mortality, providing guidance to help individual review committees standardize their findings to make them comparable across states. However, the CDC still isn’t involved directly in the reviews and, so far, the committees continue to operate independently from one another, says Goodman.

It’s a leadership void that in the past few years has been filled in part by a private-sector actor.

Though the program was built for developing countries with maternal mortality outcomes far worse than the US, Naveen Rao, the doctor who leads it, says Merck for Mothers was expanded to include the US in response to the poor state of childbirth outcomes in the country.

I hope that helps.
