Study: Prenatal supplements fail to meet nutrient needs
Although drugstore shelves might suggest otherwise,
In a new study published in the American Journal of Clinical Nutrition, investigators observed what many physicians have long suspected: Most prenatal vitamins and other supplements do not adequately make up the difference of what food-based intake of nutrients leave lacking. Despite patients believing they are getting everything they need with their product purchase, they fall short of guideline-recommended requirements.
“There is no magic pill,” said Katherine A. Sauder, PhD, an associate professor of pediatrics at the University of Colorado Anschutz Medical Campus, Aurora, and lead author of the study. “There is no easy answer here.”
The researchers analyzed 24-hour dietary intake data from 2,450 study participants across five states from 2007 to 2019. Dr. Sauder and colleagues focused on six of the more than 20 key nutrients recommended for pregnant people and determined the target dose for vitamin A, vitamin D, folate, calcium, iron, and omega-3 fatty acids.
The researchers tested more than 20,500 dietary supplements, of which 421 were prenatal products. Only 69 products – three prenatal – included all six nutrients. Just seven products – two prenatal – contained target doses for five nutrients. Only one product, which was not marketed as prenatal, contained target doses for all six nutrients but required seven tablets a serving and cost patients approximately $200 a month.
For many years, Dr. Sauder and her colleagues have struggled to identify the gold standard of vitamins for pregnant patients.
More than half of pregnant people in the United States are at risk of inadequate intake of vitamin D, folate, and iron from their diet alone, and one-third are at risk for insufficient intake of vitamin A and calcium.
Although more than 70% of pregnant women take dietary supplements, the products do not eliminate the risks for deficiencies.
The effects of inadequate nutrition during pregnancy may include neural tube defects, alterations in cardiovascular structure, and impaired neurocognitive development.
The researchers also looked at the challenges within the dietary supplement industry. The U.S. Food and Drug Administration regulates dietary supplements as foods rather than drugs and therefore does not require third-party verification that would ensure product ingredients match labels.
The researchers acknowledged the challenges in creating a one-size-fits-all nutritional supplement.
“The supplement industry is difficult, because you’re trying to create a product that works for a large, diverse group of people, but nutrition is very personal,” Dr. Sauder said.
Kendra Segura, MD, an ob.gyn. at the To Help Everyone Health and Wellness Center, Los Angeles, said she was unsurprised by the results.
“There’s no good prenatal vitamin out there,” Dr. Segura said. “There’s no ‘best.’ ”
Dr. Segura said she advises her patients to focus on increased nutritional intake with foods but added that that the lack of nutrients in diets and the need for supplements reflects the lack of availability of healthy food in some communities (known as “food deserts”), as well as poor dietary choices.
Diana Racusin, MD, an assistant professor of obstetrics, gynecology, and reproductive services at the University of Texas Health Science Center’s McGovern Medical School, Houston, also “wasn’t terribly surprised” by the findings. She stresses the importance of what patients eat more than the availability of supplements.
“What this is really showing us is we have work to do with our nutrition,” Dr. Racusin said.
Dr. Sauder’s biggest takeaway from her study is the need for more patient guidance for their nutrition beyond advising a supplement.
“We need better support for women to help them improve their diet during pregnancy so that they’re getting the nutrients they need from food,” she said, “and not having to rely on supplements as much.”
The study was supported by the Environmental Influences on Child Health Outcomes Program of the National Institutes of Health and by the nonprofit organization Autism Speaks. Dr. Sauder reports no relevant financial relationships. Two coauthors reported various conflicts of interest.

FROM THE AMERICAN JOURNAL OF CLINICAL NUTRITION
Oophorectomies continue to dominate torsion treatment
Prompt surgical management is essential in cases of ovarian torsion in order to salvage ovarian function, and recent studies have shown that conservative management with detorsion does not increase postoperative complications, compared with oophorectomy, wrote Hannah Ryles, MD, of the University of Pennsylvania, Philadelphia, and colleagues.
The American College of Obstetricians and Gynecologists issued practice guidelines in November 2016 that recommended ovarian conservation rather than oophorectomy to manage adnexal torsion in women wishing to preserve fertility. However, the impact of this guideline on clinical practice and surgical patterns remains unclear, the researchers said.
In a study published in Obstetrics and Gynecology, the researchers reviewed data from 402 patients who underwent surgeries before the updated ACOG guidelines (2008-2016) and 1,389 who underwent surgeries after the guidelines (2017-2020). Surgery data came from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. The study population included women aged 18-50 years who underwent adnexal torsion surgery and were identified as having either oophorectomy or ovarian conservation surgery.
A total of 1,791 surgeries performed for adnexal torsion were included in the study; 542 (30.3%) involved ovarian conservation and 1,249 (69.7%) involved oophorectomy.
The proportion of oophorectomies was similar during the periods before and after the guidelines (71.9% vs. 69.1%; P = .16). However, the proportion of oophorectomies changed significantly across the entire study period, by approximately –1.6% each year.
Factors significantly associated with oophorectomy compared with ovarian conservation included older age (35 years vs. 28 years), higher body mass index (29.2 kg/m2 vs. 27.5 kg/m2), anemia (12.2% vs. 7.2%), hypertension (10.4% vs. 3.1%), and higher American Society of Anesthesiologists classification.
“There remains no defined acceptable rate of oophorectomy; this decision involves multiple factors, such as fertility and other patient desires after a risk and benefit discussion, menopausal status, concern for malignancy, and safety and feasibility of conservative procedures,” the researchers wrote in their discussion. However, in emergency situations, it may be difficult to determine a patient’s preferences, and a lack of desire for future fertility may be presumed, which may contribute to the relatively high oophorectomy rates over time, they said.
The findings were limited by several factors including the retrospective design and lack of data on surgical history, histopathology, and intraoperative appearance of the ovary, as well as lack of clinical data including the time from presentation to diagnosis or surgery, the researchers noted. “Although we were also unable to determine obstetric history and fertility desires, our median age of 32 years reflects a young cohort that was limited to women of reproductive age,” they added.
However, the results reflect studies suggesting that clinical practice often lags behind updated guidelines, and the findings were strengthened by the use of the NSQIP database and reflect a need for greater efforts to promote ovarian conservation in accordance with the current guidelines, the researchers concluded.
Consider unilateral oophorectomy
The current study highlights the discrepancy between the ACOG guidelines and clinical practice, with “disappointingly low” rates of ovarian preservation in the adult population, wrote Riley J. Young, MD, and Kimberly A. Kho, MD, both of the University of Texas Southwestern Medical Center, Dallas, in an accompanying editorial. The reasons for the discrepancy include clinical concerns for conserving a torsed ovary and the difficulty of assessing fertility desires in an emergency situation, they said.
However, consideration of unilateral oophorectomy as an option should be part of clinical decision-making, according to the editorialists. Previous studies suggest that retention of a single ovarian may still allow for a successful pregnancy, and the effects of unilateral oophorectomy have been studied in infertility and assisted reproductive technology settings.
Women with a single ovary have fewer eggs and require higher amounts of gonadotropins, but pregnancy is possible, the editorialists said. However, the long-term effects of unilateral oophorectomy are uncertain, and potential detrimental outcomes include increased mortality and cognitive impairment; therefore “we aim for premenopausal ovaries simply to be conserved, whether fertility is the stated goal or not,” they noted. This may include consideration of unilateral oophorectomy. “Each ovary conserved at midnight moves us closer to a more acceptable ovarian conservation rate,” they concluded.
The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Kho disclosed funding to her institution from Hologic for being on an investigator-initiated study, Dr. Young had no financial conflicts to disclose.

Glutathione a potential biomarker for postpartum suicide
Approximately 10,000 suicide deaths are recorded in Brazil every year. The suicide risk is highest among patients with depressive disorders, particularly women (> 18% vs. 11% for men).
There are countless people who work to prevent suicide, and the challenges they face are many. But now, on the horizon, there are new tools that could prove invaluable to their efforts – tools such as biomarkers. In a study recently published in the journal Frontiers in Psychiatry, researchers from the Catholic University of Pelotas (UCPel), Brazil, reported an association of glutathione (GSH) with the degree of suicide risk in women at 18 months postpartum. Specifically, they found that reduced serum GSH levels were significantly lower for those with moderate to high suicide risk than for those without suicide risk. Their findings suggest that GSH may be a potential biomarker or etiologic factor among women at risk for suicide, with therapeutic implications.
This was a case-control study nested within a cohort study. From this cohort, 45 women were selected at 18 months postpartum. Thirty of them had mood disorders, such as major depression and bipolar disorder. The other 15 participants, none of whom had a mood disorder, made up the control group.
Depression and the risk for suicide were assessed using the Mini International Neuropsychiatric Interview Plus (MINI-Plus 5.0.0 Brazilian version), module A and module C, respectively. Blood samples were collected to evaluate serum levels of the following oxidative stress biomarkers: reactive oxygen species, superoxide dismutase, and GSH.
The prevalence of suicide risk observed in the women at 18 months postpartum was 24.4%. The prevalence of suicide risk in the mood disorder group was 36.7%.
In addition, the statistical analysis found that women with moderate to high suicide risk had cerebral redox imbalance, resulting in a decrease in blood GSH levels.
The study team was led by neuroscientist Adriano Martimbianco de Assis, PhD, the coordinator of UCPel’s postgraduate program in health and behavior. He said that the correlation identified between GSH serum levels and suicide risk gives rise to two possible applications: using GSH as a biomarker for suicide risk and using GSH therapeutically.
Regarding the former application, Dr. Martimbianco de Assis explained that additional studies are needed to take a step forward. “Although we believe that most of the GSH came from the brain – given that it’s the brain’s main antioxidant – as we analyze blood samples, we’re not yet able to rule out the possibility that it came from other organs,” he said in an interview. So, confirming that hypothesis will require studies that involve imaging brain tissue. According to Dr. Martimbianco de Assis, once there is confirmation, it will be possible to move to using the antioxidant as a biomarker for suicide risk.
He also shared his views about the second application: using GSH therapeutically. “We already know that there are very simple alternatives that can influence GSH levels, [and they] mostly have to do with exercise and [improving the quality of] the food one eats. But there are also drugs: for example, N-acetyl cysteine, which is a precursor of GSH.” Adopting strategies to increase the levels of this antioxidant in the body should reverse the imbalance identified in the study and, as a result, may lead to lowering the risk for suicide. But, he reiterated, “getting to a place where GSH [can be used] in clinical practice hinges on getting that confirmation that it did, in fact, come from the brain. Recall that our study found lower levels of GSH in women at risk for suicide.”
Even though the study evaluated postpartum women, it’s possible that the results can be extrapolated to other populations, said Dr. Martimbianco de Assis. This is because when the data were collected, 18 months had already passed since giving birth. The participants’ physiological condition at that point was more similar to the one prior to becoming pregnant.
The UCPel researchers continue to follow the cohort. “We intend to continue monitoring GSH levels at other times. Forty-eight months have now passed since the women gave birth, and the idea is to continue studying [the patients involved in the study],” said Dr. Martimbianco de Assis, adding that the team also intends to analyze brain tissue from in vitro studies using cell cultures.

Blood samples were collected to evaluate serum levels of the following oxidative stress biomarkers: reactive oxygen species, superoxide dismutase, and GSH.
The prevalence of suicide risk observed in the women at 18 months postpartum was 24.4%. The prevalence of suicide risk in the mood disorder group was 36.7%.
In addition, the statistical analysis found that women with moderate to high suicide risk had cerebral redox imbalance, resulting in a decrease in blood GSH levels.
The study team was led by neuroscientist Adriano Martimbianco de Assis, PhD, the coordinator of UCPel’s postgraduate program in health and behavior. He said that the correlation identified between GSH serum levels and suicide risk gives rise to two possible applications: using GSH as a biomarker for suicide risk and using GSH therapeutically.
Regarding the former application, Dr. Martimbianco de Assis explained that additional studies are needed to take a step forward. “Although we believe that most of the GSH came from the brain – given that it’s the brain’s main antioxidant – as we analyze blood samples, we’re not yet able to rule out the possibility that it came from other organs,” he said in an interview. So, confirming that hypothesis will require studies that involve imaging brain tissue. According to Dr. Martimbianco de Assis, once there is confirmation, it will be possible to move to using the antioxidant as a biomarker for suicide risk.
He also shared his views about the second application: using GSH therapeutically. “We already know that there are very simple alternatives that can influence GSH levels, [and they] mostly have to do with exercise and [improving the quality of] the food one eats. But there are also drugs: for example, N-acetyl cysteine, which is a precursor of GSH.” Adopting strategies to increase the levels of this antioxidant in the body should reverse the imbalance identified in the study and, as a result, may lead to lowering the risk for suicide. But, he reiterated, “getting to a place where GSH [can be used] in clinical practice hinges on getting that confirmation that it did, in fact, come from the brain. Recall that our study found lower levels of GSH in women at risk for suicide.”
Even though the study evaluated postpartum women, it’s possible that the results can be extrapolated to other populations, said Dr. Martimbianco de Assis. This is because when the data were collected, 18 months had already passed since giving birth. The participants’ physiological condition at that point was more similar to the one prior to becoming pregnant.
The UCPel researchers continue to follow the cohort. “We intend to continue monitoring GSH levels at other times. Forty-eight months have now passed since the women gave birth, and the idea is to continue studying [the patients involved in the study],” said Dr. Martimbianco de Assis, adding that the team also intends to analyze brain tissue from in vitro studies using cell cultures.

IUD-released levonorgestrel eases heavy menstrual periods
Median blood loss decreased by more than 90% in the first three cycles. Overall, treatment was successful in 81.8% of 99 patients (95% confidence interval, 74.2%-89.4%), according to findings published in Obstetrics & Gynecology.
Already approved for contraception, the IUD (Liletta) had substantial benefits for quality of life in measures such as sleep, pain/cramping, and daily functioning, wrote a group led by Mitchell D. Creinin, MD, a professor in the department of obstetrics and gynecology at University of California, Davis.
“This study provides evidence of high efficacy, as expected, for the Liletta levonorgestrel 52 mg IUD for heavy menstrual bleeding treatment,” Dr. Creinin said in an interview.
Racially diverse cohort
Conducted at 29 U.S. sites prior to seeking FDA registration for this new use, the phase 3 open-label trial of the 52 mg progestin-releasing IUD enrolled 105 participants with a mean age of 35.4 years. Unlike previous trials, this one included obese or severely obese women (44.8%), with 42 participants having a body mass index (BMI) of more than 35 kg/m2, and also 28 nulliparous women (27.6%).
Those with abnormalities such as fibroids or coagulopathies were excluded. Although most of the cohort was White (n = 68), the study included Black (n = 25), Asian (n = 4), and Hispanic (n = 10) women, plus 7 from other minorities, suggesting the results would be widely applicable.
Mean baseline blood loss in the cohort ranged from 73 mL to 520 mL (median, 143 mL). Of 89 treated women with follow-up, participants had a median absolute blood-loss decreases of 93.3% (86.1%-97.8%) at cycle three and 97.6% (90.4%-100%) at cycle six. Median bleeding reductions at cycle six were similar between women with and without obesity at 97.6% and 97.5%, respectively, and between nulliparous and parous women at 97.0% and 98.1%, respectively (P = .43). The study, however, was not sufficiently powered to fully analyze these subgroups, the authors acknowledged.
Although results were overall comparable with those of a previous study on a different IUD, the expulsion rate was somewhat higher, at 9%, than the 6% reported in the earlier study.
“Although this strategy for reducing blood loss is not new, this study is notable because it looked at high-BMI women and nulliparous women,” said Kathryn J. Gray, MD, PhD, an attending physician in the department of obstetrics and gynecology at Brigham and Women’s Hospital in Boston, who was not involved in the research.“No prior trials have included patients with BMIs exceeding 35 kg/m2 or nulliparous patients, while this study enrolled a full array of patients, which allowed exploratory analyses of these subpopulations,” Dr. Creinin confirmed.
According to Dr. Gray, the IUD approach has advantages over systemic treatment with oral medication. “First, treatment is not user-dependent so the user doesn’t have to remember to take it. In addition, because the medication is locally targeted in the uterus, it is more effective and there is less fluctuation and variability in drug levels than when taken orally.”
As to treatment durability, Dr. Creinin said, “Long-term studies in a population being treated for heavy menstrual bleeding would be helpful to have an idea of how long this effect lasts. Still, there is no reason to expect that the effect will not last for many years.”
And with this treatment, he added, both patient and clinician can readily detect its effect. “If bleeding begins to increase, they will know!”
Would there be a lingering residual effect even after removal of the IUD? “That is an excellent question that remains to be answered,” Dr. Creinin said. “There are no data on when the heavy bleeding returns, but it would be expected to do so.”
This study was funded, designed, and supervised by Medicines360, which also provided the study treatment. Dr. Creinin disclosed financial relationships with various private-sector companies, including Medicines360, Organon, Fuji Pharma, GlaxoSmithKline, and Merck & Co. Multiple study coauthors disclosed similar financial ties to industry partners, including Medicines360. Dr. Gray had no potential conflicts of interest with regard to her comments.

FROM OBSTETRICS & GYNECOLOGY
Outpatient costs top drug costs in some insured, working women with breast cancer
Among a sample of younger women with invasive breast cancer and employer-sponsored insurance, outpatient-related out-of-pocket (OOP) costs were greater than drug costs.
For these same patients, prescriptions were largely for nonproprietary anticancer drugs and entailed limited OOP costs. For women with high-deductible health plans (HDHPs) and commercially driven health plans (CDHPs), OOP costs were higher, compared with coverage by more generous plans, according to the Research Letter published in JAMA Network Open.
“You would expect that people undergoing cancer treatment should not have to face very high out-of-pocket costs associated with care regardless of treatment modality because their treatment is largely guideline-indicated, and they have no choices,” stated corresponding author Rena Conti, PhD, associate professor with the school of business, Boston University, in an interview. “If you are diagnosed with cancer and undergoing treatment, you’re following the recommendation of your doctor, and your doctor is following standard protocols for treatment. In that scenario, Economics 101 suggests that people should not have to pay anything or [should pay] very little, especially for things that are cheap and are known to be effective, because there’s no overuse. Where normally we think that out-of-pocket costs are meant to control overuse, people with breast cancer are not opting to get more than indicated chemotherapy or radiation.”
The analysis of 25,224 women with invasive breast cancer diagnosis and claims for 1 or more of 14 oral anticancer drugs revealed that OOP costs for nondrug outpatient claims represented 79.0% of total costs. OOP drug costs were modest, with a 30-day supply ranging from $0.57-$0.60 for tamoxifen to $134.08-$141.07 for palbociclib.
“We were interested in understanding to what extent women who are insured with private insurance are exposed to out-of-pocket costs for standard breast cancer treatment, both in looking at drugs, but also the other aspects of the treatments they undergo.”
High OOP costs for the oral anticancer prescription drugs that are central to breast cancer treatment are associated with treatment nonadherence and discontinuation. Little has been known, however, about OOP costs of treatment associated with invasive breast cancer among employer-insured women younger than 65 years, the paper says.
“This population may face significant financial burdens related to long-term hormonal-based prevention and enrollment in high-deductible health plans and consumer-driven health plans,” the authors state in their paper.
In the cross-sectional study, which used the national 2018 Marative MarketScan database, 23.1% were HDHP- or CDHP-insured. Fifty-one percent had no OOP costs for drugs. The total mean estimated OOP cost, however, was $1,502.23 per patient, with inpatient costs representing only $112.41 (95% confidence interval, $112.40-$112.42); outpatient costs were $1,186.27 (95% CI, $1,185.67-$1,188.16). Pharmaceutical costs were $203.55 (95% CI, $203.34-$203.78).“We were surprised to find that the vast majority were getting breast cancer treatment with older, very effective, very safe, relatively inexpensive drugs and had limited out-of-pocket costs with some variation – higher costs for the few receiving newer, expensive drugs. The backbone of treatment is the older, generic drugs, which are cheap for both the insurers and the patients. But we found also that women are facing high out-of-pocket costs for nondrug-based therapy – specifically for doctor visits, getting check-ups, diagnostic scans, and maybe other types of treatment, as well. ... It’s a very different story than the one typically being told about the preponderance of out-of-pocket costs being drug-related,” Dr. Conti said.
The explanation may be that progress in breast cancer treatment over the last decades has led to effective treatments that are largely now inexpensive. The situation is different with ovarian cancer and many blood cancers such as chronic lymphocytic leukemia and multiple myeloma. For them, the new, innovative, safe, and effective drugs are very expensive, she noted.
“I think that insurers can modulate the out-of-pocket costs associated with drug treatment through formulary design and other tools they have. It’s less easy for them to modulate out-of-pocket costs associated with other modalties of care. Still, for medical care that is obviously necessary, there needs to be a cap on what women should have to pay,” Dr. Conti said.
A further concern raised by Dr. Conti is shrinking Medicaid coverage with the expiration of COVID-specific expanded Medicaid eligibility.
“Policy folks are closely watching the size of uninsured populations and also the growing importance of the high deductible and consumer-driven plans in which patients face high out-of-pocket first dollar coverage for care. With Medicaid rolls shrinking, we’ll see more people in low-premium, not well-insured plans. Americans’ exposure to higher costs for guideline-recommended care might grow, especially as more of them are independent contractors in the gig economy and not working for big corporations.”
“We worry that if and when they get a diagnosis of breast cancer, which is common among younger women, they are going to be faced with costs associated with their care that are going to have to be paid out-of-pocket – and it’s not going to be for the drug, it’s the other types of care. Doctors should know that the younger patient population that they are serving might be facing burdens associated with their care.”
Dr. Conti added, “Among women who are underinsured, there is a clear burden associated with cancer treatment. Reform efforts have largely focused on reducing out-of-pocket costs for seniors and have not focused much on guideline-consistent care for those under 65 who are working. Their burden can be quite onerous and cause financial harm for them and their families, resulting in worse health,” she continued, “Policy attention should go to unburdening people who have a serious diagnosis and who really have to be treated. There’s very good evidence that imposing additional out-of-pocket costs for guideline-consistent care causes people to make really hard decisions about paying rent versus paying for meds, about splitting pills and not doing all the things their physician is recommending, and about staying in jobs they don’t love but are locked into [because of health coverage].”
Dr. Conti concluded, “The good news is that, in breast cancer, the drugs work and are cheap. But the bad news is that there are many people who are underinsured and therefore, their care still has a high out-of-pocket burden. ACA radically changed working age people’s ability to qualify for insurance and be insured, but that didn’t mean that they are really well-covered when they become sick. They are still in peril over high out-of-pocket costs because of the proliferation of plans that are very skimpy. Women think they are insured until they get a diagnosis.”
Noting study limitations, Dr. Conti said that OOP costs cited are an underestimate, because many patients will also be treated for other comorbidities and complications related to treatment.
The authors disclosed no conflicts of interest. The study was funded by the American Cancer Society.

For them, the new, innovative, safe, and effective drugs are very expensive, she noted.
“I think that insurers can modulate the out-of-pocket costs associated with drug treatment through formulary design and other tools they have. It’s less easy for them to modulate out-of-pocket costs associated with other modalties of care. Still, for medical care that is obviously necessary, there needs to be a cap on what women should have to pay,” Dr. Conti said.
A further concern raised by Dr. Conti is shrinking Medicaid coverage with the expiration of COVID-specific expanded Medicaid eligibility.
“Policy folks are closely watching the size of uninsured populations and also the growing importance of the high deductible and consumer-driven plans in which patients face high out-of-pocket first dollar coverage for care. With Medicaid rolls shrinking, we’ll see more people in low-premium, not well-insured plans. Americans’ exposure to higher costs for guideline-recommended care might grow, especially as more of them are independent contractors in the gig economy and not working for big corporations.”
“We worry that if and when they get a diagnosis of breast cancer, which is common among younger women, they are going to be faced with costs associated with their care that are going to have to be paid out-of-pocket – and it’s not going to be for the drug, it’s the other types of care. Doctors should know that the younger patient population that they are serving might be facing burdens associated with their care.”
Dr. Conti added, “Among women who are underinsured, there is a clear burden associated with cancer treatment. Reform efforts have largely focused on reducing out-of-pocket costs for seniors and have not focused much on guideline-consistent care for those under 65 who are working. Their burden can be quite onerous and cause financial harm for them and their families, resulting in worse health,” she continued, “Policy attention should go to unburdening people who have a serious diagnosis and who really have to be treated. There’s very good evidence that imposing additional out-of-pocket costs for guideline-consistent care causes people to make really hard decisions about paying rent versus paying for meds, about splitting pills and not doing all the things their physician is recommending, and about staying in jobs they don’t love but are locked into [because of health coverage].”
Dr. Conti concluded, “The good news is that, in breast cancer, the drugs work and are cheap. But the bad news is that there are many people who are underinsured and therefore, their care still has a high out-of-pocket burden. ACA radically changed working age people’s ability to qualify for insurance and be insured, but that didn’t mean that they are really well-covered when they become sick. They are still in peril over high out-of-pocket costs because of the proliferation of plans that are very skimpy. Women think they are insured until they get a diagnosis.”
Noting study limitations, Dr. Conti said that OOP costs cited are an underestimate, because many patients will also be treated for other comorbidities and complications related to treatment.
The authors disclosed no conflicts of interest. The study was funded by the American Cancer Society.

Routine third-trimester ultrasounds can detect likely breech births
Implementing universal ultrasound during the third trimester of pregnancy significantly reduced the number of undiagnosed breech presentations, according to a study published in PLOS Medicine. The effects held if sonographers used a traditional ultrasound machine or if midwives used a handheld ultrasound tool to perform what is known as a point-of-care ultrasound (POCUS) procedure.
“Giving pregnant women a third-trimester scan reduces the rate of undetected breech in labor by over two-thirds, which reduces the chances of harm to the baby,” said Asma Khalil, MBBCh, MD, professor of obstetrics and maternal-fetal medicine at the University of London’s St. George’s Hospital, and a coauthor of the new study.
Routine ultrasounds typically are performed from the 10th to the 13th week of pregnancy, not during the third trimester, when the risk for a breech birth would be most apparent. Breech births occur in 3%-4% of pregnancies, raising the risk that babies will experience broken bones or hemorrhage. Knowing that breech is possible before birth enables physicians to discuss options with the pregnant woman in advance, Dr. Khalil said. These steps include rotating the baby in the uterus or conducting a cesarean delivery. Such counseling is not possible if breech is undetected until spontaneous or induced labor.
“Breech presentation at term is not very common, but diagnosing it prior to the onset of labor or induction of labor offers patients much more flexibility in terms of options and planning,” said Cecilia B. Leggett, MD, a resident in obstetrics and gynecology at Cedars-Sinai in Los Angeles. Dr. Leggett, who was not involved in the study, has shown that handheld devices are as accurate at assessing fetal weight as are standard ultrasound machines.
Two tools, same result
Dr. Khalil and her colleagues compared the rates of undiagnosed breech presentations before and after implementing universal third-semester ultrasound at two hospitals in the United Kingdom. The requirement began in 2020; the study compared the rate of undiagnosed breeches from the period of 2016-2020 with that of 2020-2021.
St. George’s Hospital in London used a traditional ultrasound machine that is read by a sonographer, whereas the Norfolk and Norwich University Hospitals, in Norwich, England, employed midwives to use a handheld ultrasound device.
The rate of undiagnosed breech cases declined from 14.2% at St. George’s before the universal ultrasound requirement (82 missed cases of 578 breech births) to 2.8% after the requirement began (7 missed cases of 251 breech births). The story was similar at Norfolk and Norwich, where 16.2% missed breech cases occurred before the requirement (27 of 167) and 3.5% missed cases were reported after it (5 of 142).
The increased accuracy of breech diagnosis before labor probably led to fewer cases of impaired blood flow to a baby’s brain at birth, Dr. Khalil’s group reported, as well as a probable reduction in the number of stillborn babies or those who die extremely young.
Traditional ultrasound scans read by sonographers are expensive, Dr. Khalil noted, whereas the portable handheld devices are much cheaper and could be used widely to improve detection of breech births. That step would require robust training about how to properly use these devices, Dr. Leggett said.
“As we see more and more studies come out about technology for POCUS, I think it’s important to keep in mind that we need the education about the tools to be as accessible as the tools themselves,” she said.
Dr. Leggett had no relevant financial relationships. Dr. Khalil is a vice president of the Royal College of Obstetricians and Gynaecologists, is a trustee and the treasurer of the International Society of Ultrasound in Obstetrics and Gynecology, and has lectured at and consulted in several ultrasound-based projects, webinars, and educational events.

FDA withdraws approval of Makena
The Food and Drug Administration has decided to withdraw approval of Makena and generic versions of the drug, the agency announced April 6.
The medication was approved in 2011 to reduce the risk for preterm birth in women who had previously experienced spontaneous preterm birth. The treatment had been approved under an accelerated pathway that required another trial to confirm clinical benefit.
A postmarketing study did not show clinical benefit, however, and the agency proposed withdrawing the drug, hydroxyprogesterone caproate injection, in 2020. The drug’s sponsor requested a hearing on the decision, and that meeting was held in October 2022.
The FDA commissioner and chief scientist subsequently reviewed submitted reports, comments, and transcripts, and made the decision to withdraw the drug.
“Effective today, Makena and its generics are no longer approved and cannot lawfully be distributed in interstate commerce,” the agency said.
“It is tragic that the scientific research and medical communities have not yet found a treatment shown to be effective in preventing preterm birth and improving neonatal outcomes – particularly in light of the fact that this serious condition has a disparate impact on communities of color, especially Black women,” FDA Commissioner Robert M. Califf, MD, said in a statement.
Risks associated with the drug include thromboembolic disorders, allergic reactions, decreased glucose tolerance, and fluid retention, regulators have noted. The agency acknowledged that some supplies of the product have already been distributed. Patients with questions should talk to their health care provider, the FDA advised.

COVID-19 in pregnancy affects growth in child’s first year of life
in a new analysis.
This “exaggerated growth pattern observed among infants with COVID-19 exposure may in some cases be a catch-up response to a prenatal growth deficit,” Mollie W. Ockene and colleagues wrote in a report published recently in the Journal of Clinical Endocrinology & Metabolism.
But given that lower birth weight and accelerated postnatal weight gain are risk factors for cardiometabolic disease, the findings “raise concern” about whether children born to mothers with prenatal COVID-19 go on to develop obesity, diabetes, or cardiovascular disease, senior coauthors Andrea G. Edlow, MD, and Lindsay T. Fourman, MD, of Massachusetts General Hospital, Boston, told this news organization.
Further studies in larger numbers of patients with longer follow-up and detailed assessments are needed, the researchers said, but this points to “a potentially increased cardiometabolic disease risk for the large global population of children with in utero COVID-19 exposure.”
It will be “important for clinicians caring for children with in utero exposure to maternal COVID-19 to be aware of this history,” Dr. Edlow and Dr. Fourman added, “and to view the child’s growth trajectory and metabolic risk factors in a holistic context that includes this prenatal infection exposure.”
COVID-19 vaccination important during and prior to pregnancy
The study also underscores the importance of primary prevention of COVID-19 among women who are contemplating pregnancy or who are already pregnant, the researchers noted, “including the need for widespread implementation of protective measures such as indoor masking and COVID-19 vaccination and boosting during or prior to pregnancy.”
Dr. Edlow and Dr. Fourman added, “Given the disproportionate impact that COVID-19 has had on historically marginalized populations, adverse health outcomes following in utero exposure to maternal COVID-19 may threaten to widen existing disparities in child health.”
On the other hand, although “COVID-19 vaccination rates lagged behind in minority populations following the initial vaccine rollout,” they noted, “these differences have fortunately narrowed over time, particularly for Hispanic individuals, though they do still persist in the Black population,” according to a recent report.
BMI trajectories during first year of life
In utero exposure to COVID-19 has been linked to fetal/neonatal morbidity and mortality, including stillbirth, preterm birth, preeclampsia, and gestational hypertension, but less is known about infant outcomes during the first year of life.
The researchers aimed to compare weight, length, and BMI trajectories over the first year of life in infants with, versus without, in utero exposure to COVID-19.
They identified 149 infants with in utero exposure to COVID-19 and 127 unexposed infants; all were born between March 30, 2020, and May 30, 2021, to mothers who participated in the Mass General Brigham COVID-19 Perinatal Biorepository.
The study excluded infants whose mothers received the vaccine (n = 5) or who had unclear vaccination status during pregnancy (n = 4) to reduce sample heterogeneity.
At the time of the study, few women had received the COVID-19 vaccine because vaccines were approved by the Food and Drug Administration for emergency use in December 2020 and the CDC recommended them for all pregnant women much later, in August 2021.
The researchers examined the weight, length, and BMI of the infants at birth, and at 2, 6, and 12 months, standardized using World Health Organization (WHO) growth charts.
Compared with mothers who did not have COVID-19 during pregnancy, those who had COVID-19 were younger (mean age, 32 vs. 34 years) and had a higher earliest BMI during pregnancy (29 vs. 26 kg/m2) and greater parity (previous births, excluding the index pregnancy, 1.2 vs. 0.9), and they were more likely to be Hispanic or Black and less likely to have private insurance.
Compared with infants exposed to COVID-19 in utero, infants who were not exposed were more likely to be male (47% vs. 55%).
Both infant groups were equally likely to be breastfed (90%).
Compared with the unexposed infants, infants born to mothers with prenatal COVID-19 had lower BMI z-scores at birth (effect size, −0.35; P = .03) and greater gain in BMI z-scores from birth to 12 months (effect size, 0.53; P = .03), but they had similar length at birth and over 12 months, after adjustment for maternal age at delivery, ethnicity, parity, insurance status, and earliest BMI during pregnancy, as well as infant sex, date of birth, and if applicable, history of breastfeeding.
The study received funding from the National Institutes of Health, Harvard Nutrition Obesity Research Center, Boston Area Diabetes Endocrinology Research Centers, American Heart Association, and Simons Foundation. Ms. Ockene has reported no relevant financial relationships. Dr. Edlow has reported being a consultant for Mirvie and receiving research funding from Merck outside the study.

Cervical screening often stops at 65, but should it?
“Did you love your wife?” asks a character in “Rose,” a book by Martin Cruz Smith.
“No, but she became a fact through perseverance,” the man replied.
Medicine also has such relationships, it seems – tentative ideas that turned into fact simply by existing long enough.
Age 65 as the cutoff for cervical screening may be one such example. It has existed for 27 years with limited science to back it up. That may soon change with the launch of a $3.3 million study that is being funded by the National Institutes of Health (NIH). The study is intended to provide a more solid foundation for the benefits and harms of cervical screening for women older than 65.
It’s an important issue: 20% of all cervical cancer cases are found in women who are older than 65. Most of these patients have late-stage disease, which can be fatal. In the United States, 35% of cervical cancer deaths occur after age 65. But women in this age group are usually no longer screened for cervical cancer.
Back in 1996, the U.S. Preventive Services Task Force recommended that for women at average risk with adequate prior screening, cervical screening should stop at the age of 65. This recommendation has been carried forward year after year and has been incorporated into several other guidelines.
For example, current guidelines from the American Cancer Society, the American College of Obstetricians and Gynecologists, and the USPSTF recommend that cervical screening stop at aged 65 for patients with adequate prior screening.
“Adequate screening” is defined as three consecutive normal Pap tests or two consecutive negative human papillomavirus tests or two consecutive negative co-tests within the prior 10 years, with the most recent screening within 5 years and with no precancerous lesions in the past 25 years.
This all sounds reasonable; however, for most women, medical records aren’t up to the task of providing a clean bill of cervical health over many decades.
Explained Sarah Feldman, MD, an associate professor in obstetrics, gynecology, and reproductive biology at Harvard Medical School, Boston: “You know, when a patient says to me at 65, ‘Should I continue screening?’ I say, ‘Do you have all your results?’ And they’ll say, ‘Well, I remember I had a sort of abnormal pap 15 years ago,’ and I say, ‘All right; well, who knows what that was?’ So I’ll continue screening.”
According to George Sawaya, MD, professor of obstetrics, gynecology, and reproductive sciences at the University of California, San Francisco, up to 60% of women do not meet the criteria to end screening at age 65. This means that each year in the United States, approximately 1.7 million women turn 65 and should, in theory, continue to undergo screening for cervical cancer.
Unfortunately, the evidence base for the harms and benefits of cervical screening after age 65 is almost nonexistent – at least by the current standards of evidence-based medicine.
“We need to be clear that we don’t really know the appropriateness of the screening after 65,” said Dr. Sawaya, “which is ironic, because cervical cancer screening is probably the most commonly implemented cancer screening test in the country because it starts so early and ends so late and it’s applied so frequently.”
Dr. Feldman agrees that the age 65 cutoff is “somewhat arbitrary.” She said, “Why don’t they want to consider it continuing past 65? I don’t really understand, I have to be honest with you.”
So what’s the scientific evidence backing up the 27-year-old recommendation?
In 2018, the USPSTF’s cervical-screening guidelines concluded “with moderate certainty that the benefits of screening in women older than 65 years who have had adequate prior screening and are not otherwise at high risk for cervical cancer do not outweigh the potential harms.”
This recommendation was based on a new decision model commissioned by the USPSTF. The model was needed because, as noted by the guidelines’ authors, “None of the screening trials enrolled women older than 65 years, so direct evidence on when to stop screening is not available.”
In 2020, the ACS carried out a fresh literature review and published its own recommendations. The ACS concluded that “the evidence for the effectiveness of screening beyond age 65 is limited, based solely on observational and modeling studies.”
As a result, the ACS assigned a “qualified recommendation” to the age-65 moratorium (defined as “less certainty about the balance of benefits and harms or about patients’ values and preferences”).
Most recently, the 2021 Updated Cervical Cancer Screening Guidelines, published by the American College of Obstetricians and Gynecologists, endorsed the recommendations of the USPSTF.
Dr. Sawaya said, “The whole issue about screening over 65 is complicated from a lot of perspectives. We don’t know a lot about the safety. We don’t really know a lot about patients’ perceptions of it. But we do know that there has to be an upper age limit after which screening is just simply imprudent.”
Dr. Sawaya acknowledges that there exists a “heck-why-not” attitude toward cervical screening after 65 among some physicians, given that the tests are quick and cheap and could save a life, but he sounds a note of caution.
“It’s like when we used to use old cameras: the film was cheap, but the developing was really expensive,” Dr. Sawaya said. “So it’s not necessarily about the tests being cheap, it’s about the cascade of events [that follow].”
Follow-up for cervical cancer can be more hazardous for a postmenopausal patient than for a younger woman, explained Dr. Sawaya, because the transformation zone of the cervix may be difficult to see on colposcopy. Instead of a straightforward 5-minute procedure in the doctor’s office, the older patient may need the operating room simply to provide the first biopsy.
In addition, treatments such as cone biopsy, loop excision, or ablation are also more worrying for older women, said Dr. Sawaya, “So you start thinking about the risks of anesthesia, you start thinking about the risks of bleeding and infection, etc. And these have not been well described in older people.”
To add to the uncertainty about the merits and risks of hunting out cervical cancer in older women, a lot has changed in women’s health since 1996.
Explained Dr. Sawaya, “This stake was put in the ground in 1996, ... but since that time, life expectancy has gained 5 years. So a logical person would say, ‘Oh, well, let’s just say it should be 70 now, right?’ [But] can we even use old studies to inform the current cohort of women who are entering this 65-year-and-older age group?”
To answer all these questions, a 5-year, $3.3 million study funded by the NIH through the National Cancer Institute is now underway.
The project, named Comparative Effectiveness Research to Validate and Improve Cervical Cancer Screening (CERVICCS 2), will be led by Dr. Sawaya and Michael Silverberg, PhD, associate director of the Behavioral Health, Aging and Infectious Diseases Section of Kaiser Permanente Northern California’s Division of Research.
It’s not possible to conduct a true randomized controlled trial in this field of medicine for ethical reasons, so CERVICCS 2 will emulate a randomized study by following the fate of approximately 280,000 women older than 65 who were long-term members of two large health systems during 2005-2022. – both before and after the crucial age 65 cutoff.
The California study will also look at the downsides of diagnostic procedures and surgical interventions that follow a positive screening result after the age of 65 and the personal experiences of the women involved.
Dr. Sawaya and Dr. Silverberg’s team will use software that emulates a clinical trial by utilizing observational data to compare the benefits and risks of screening continuation or screening cessation after age 65.
In effect, after 27 years of loyalty to a recommendation supported by low-quality evidence, medicine will finally have a reliable answer to the question, Should we continue to look for cervical cancer in women over 65?
Dr. Sawaya concluded: “There’s very few things that are packaged away and thought to be just the truth. And this is why we always have to be vigilant. ... And that’s what keeps science so interesting and exciting.”
Dr. Sawaya has disclosed no relevant financial relationships. Dr. Feldman writes for UpToDate and receives several NIH grants.

Cesarean deliveries drop in women at low risk
Although clinically indicated cesarean deliveries may improve outcomes for mothers and infants, “when not clinically indicated, cesarean delivery is a major surgical intervention that increases risk for adverse outcomes,” wrote Anna M. Frappaolo of Columbia University College of Physicians and Surgeons, New York, and colleagues.
The Healthy People 2030 campaign includes the reduction of cesarean deliveries, but trends in these procedures, especially with regard to diagnoses of labor arrest, have not been well studied, the researchers said.
In an analysis published in JAMA Network Open, the researchers reviewed delivery hospitalizations using data from the National Inpatient Sample from 2000 to 2019.
Births deemed low risk for cesarean delivery were identified by using criteria of the Society for Maternal-Fetal Medicine and additional criteria, and joinpoint regression analysis was used to estimate changes.
The researchers examined overall trends in cesarean deliveries as well as trends for three specific diagnoses: nonreassuring fetal status, labor arrest, and obstructed labor.
The final analysis included 40,517,867 deliveries; of these, 4,885,716 (12.1%) were cesarean deliveries.
Overall, cesarean deliveries in patients deemed at low risk increased from 9.7% in 2000 to 13.9% in 2009, then plateaued and decreased from 13.0% in 2012 to 11.1% in 2019. The average annual percentage change (AAPC) for cesarean delivery was 6.4% for the years from 2000 to 2005, 1.2% from 2005 to 2009, and −2.2% from 2009 to 2019.
Cesarean delivery for nonreassuring fetal status increased over the entire study period, from 3.4% in 2000 to 5.1% in 2019. By contrast, overall cesarean delivery for labor arrest increased from 3.6% in 2000 to a high of 4.8% in 2009, then decreased to 2.7% in 2019. Cesarean deliveries with a diagnosis of obstructed labor decreased from 0.9% in 2008 to 0.3% in 2019.
More specifically, cesarean deliveries for labor arrest in the active phase, latent phase, and second stage of labor increased from 1.5% to 2.1%, 1.1% to 1.5%, and 0.9% to 1.3%, respectively, from 2000 to 2009, and decreased from 2.1% to 1.7% for the active phase, from 1.5% to 1.2% for the latent phase, and from 1.2% to 0.9% for the second stage between 2010 and 2019.
Patients with increased odds of cesarean delivery were older (aged 35-39 years vs. 25-29 years, adjusted odds ratio 1.27), delivered in a hospital in the South vs. the Northeast of the United States (aOR 1.11), and were more likely to be non-Hispanic Black vs. non-Hispanic White (OR 1.23).
Notably, changes in nomenclature and interpretation of intrapartum electronic fetal heart monitoring occurred during the study period, with recommendations for the adoption of a three-tiered system for fetal heart rate patterns in 2008. “It is possible that current evidence and nomenclature related to intrapartum FHR interpretation may result in identification of a larger number of fetuses deemed at indeterminate risk for abnormal acid-base status,” the researchers wrote in their discussion.
The study findings were limited by several factors including the use of administrative discharge data rather than clinical records, the exclusion of patients with chronic conditions associated with cesarean delivery, changes in billing codes during the study period, and the inability to account for the effect of health factors, maternal age, and use of assisted reproductive technology, the researchers noted.
However, the results were strengthened by the large sample size and 20-year study period, as well as the stratification of labor arrest by stage, and suggest uptake of newer recommendations, they said. “Future reductions in cesarean deliveries among patients at low risk for cesarean delivery may be dependent on improved assessment of intrapartum fetal status,” they concluded.
Consider populations and outcomes in cesarean risk assessment
The decreasing rates of cesarean deliveries in the current study can be seen as positive, but more research is needed to examine maternal and neonatal outcomes, and to consider other conditions that affect risk for cesarean delivery, Paolo Ivo Cavoretto, MD, and Massimo Candiani, MD, of IRCCS San Raffaele Scientific Institute, and Antonio Farina, MD, of the University of Bologna, Italy, wrote in an accompanying editorial.
Notably, the study authors identified a population aged 15-39 years as low risk, and an increased risk for cesarean delivery within this range increased with age. “Maternal age remains a major risk factor associated with the risk of cesarean delivery, both from results of this study and those of previous analyses assessing its independence from other related risk factors,” the editorialists said.
The study findings also reflect the changes in standards for labor duration during the study period, they noted. The longer duration of labor may reduce cesarean delivery rates, but it is not without maternal and fetal-neonatal risks, they wrote.
“To be sure that the described trend of cesarean delivery rate reduction can be considered positive, there would be the theoretical need to analyze other maternal-fetal-neonatal outcomes (e.g., rates of operative deliveries, neonatal acidemia, intensive care unit use, maternal hemorrhage, pelvic floor trauma and dysfunction, and psychological distress),” the editorialists concluded.
More research needed to explore clinical decisions
“Reducing the cesarean delivery rate is a top priority, but evidence is lacking on an optimal rate that improves maternal and neonatal outcomes,” Iris Krishna, MD, a maternal-fetal medicine specialist at Emory University, Atlanta, said in an interview.
“Hospital quality and safety committees have been working to decrease cesarean deliveries amongst low-risk women, and identifying contemporary trends gives us insight on whether some of these efforts have translated to a lower cesarean delivery rate,” she said.
Dr. Krishna said she was not surprised by the higher cesarean section rate in the South. “The decision for cesarean delivery is multifaceted, and although this study was not able to assess clinical indications for cesarean delivery or maternal and fetal outcomes, we cannot ignore that social determinants of health contribute greatly to overall health outcomes,” she said. The trends in the current study further underscore the geographic disparities in access to health care present in the South, she added.
“This study notes that cesarean delivery for nonreassuring fetal status increased; however, nonreassuring fetal status as an indication for cesarean delivery can be subjective,” Dr. Krishna said. “Hospital quality and safety committees should consider reviewing the clinical scenarios that led to this decision to identify opportunities for improvement and further education,” she said.
“Defining contemporary trends in cesarean delivery for low-risk patients has merit, but the study findings should be interpreted with caution,” said Dr. Krishna, who is a member of the Ob.Gyn. News advisory board. More research is needed to define an optimal cesarean section rate that promotes positive maternal and fetal outcomes, and to determine whether identifying an optimal rate should be based on patient risk profiles, she said.
The study received no outside funding. Lead author Ms. Frappaolo had no financial conflicts to disclose; nor did the editorial authors or Dr. Krishna.

Notably, changes in nomenclature and interpretation of intrapartum electronic fetal heart monitoring occurred during the study period, with recommendations for the adoption of a three-tiered system for fetal heart rate patterns in 2008. “It is possible that current evidence and nomenclature related to intrapartum FHR interpretation may result in identification of a larger number of fetuses deemed at indeterminate risk for abnormal acid-base status,” the researchers wrote in their discussion.
The study findings were limited by several factors including the use of administrative discharge data rather than clinical records, the exclusion of patients with chronic conditions associated with cesarean delivery, changes in billing codes during the study period, and the inability to account for the effect of health factors, maternal age, and use of assisted reproductive technology, the researchers noted.
However, the results were strengthened by the large sample size and 20-year study period, as well as the stratification of labor arrest by stage, and suggest uptake of newer recommendations, they said. “Future reductions in cesarean deliveries among patients at low risk for cesarean delivery may be dependent on improved assessment of intrapartum fetal status,” they concluded.
Consider populations and outcomes in cesarean risk assessment
The decreasing rates of cesarean deliveries in the current study can be seen as positive, but more research is needed to examine maternal and neonatal outcomes, and to consider other conditions that affect risk for cesarean delivery, Paolo Ivo Cavoretto, MD, and Massimo Candiani, MD, of IRCCS San Raffaele Scientific Institute, and Antonio Farina, MD, of the University of Bologna, Italy, wrote in an accompanying editorial.
Notably, the study authors identified a population aged 15-39 years as low risk, and an increased risk for cesarean delivery within this range increased with age. “Maternal age remains a major risk factor associated with the risk of cesarean delivery, both from results of this study and those of previous analyses assessing its independence from other related risk factors,” the editorialists said.
The study findings also reflect the changes in standards for labor duration during the study period, they noted. The longer duration of labor may reduce cesarean delivery rates, but it is not without maternal and fetal-neonatal risks, they wrote.
“To be sure that the described trend of cesarean delivery rate reduction can be considered positive, there would be the theoretical need to analyze other maternal-fetal-neonatal outcomes (e.g., rates of operative deliveries, neonatal acidemia, intensive care unit use, maternal hemorrhage, pelvic floor trauma and dysfunction, and psychological distress),” the editorialists concluded.
More research needed to explore clinical decisions
“Reducing the cesarean delivery rate is a top priority, but evidence is lacking on an optimal rate that improves maternal and neonatal outcomes,” Iris Krishna, MD, a maternal-fetal medicine specialist at Emory University, Atlanta, said in an interview.
“Hospital quality and safety committees have been working to decrease cesarean deliveries amongst low-risk women, and identifying contemporary trends gives us insight on whether some of these efforts have translated to a lower cesarean delivery rate,” she said.
Dr. Krishna said she was not surprised by the higher cesarean section rate in the South. “The decision for cesarean delivery is multifaceted, and although this study was not able to assess clinical indications for cesarean delivery or maternal and fetal outcomes, we cannot ignore that social determinants of health contribute greatly to overall health outcomes,” she said. The trends in the current study further underscore the geographic disparities in access to health care present in the South, she added.
“This study notes that cesarean delivery for nonreassuring fetal status increased; however, nonreassuring fetal status as an indication for cesarean delivery can be subjective,” Dr. Krishna said. “Hospital quality and safety committees should consider reviewing the clinical scenarios that led to this decision to identify opportunities for improvement and further education,” she said.
“Defining contemporary trends in cesarean delivery for low-risk patients has merit, but the study findings should be interpreted with caution,” said Dr. Krishna, who is a member of the Ob.Gyn. News advisory board. More research is needed to define an optimal cesarean section rate that promotes positive maternal and fetal outcomes, and to determine whether identifying an optimal rate should be based on patient risk profiles, she said.
The study received no outside funding. Lead author Ms. Frappaolo had no financial conflicts to disclose; nor did the editorial authors or Dr. Krishna.
Although clinically indicated cesarean deliveries may improve outcomes for mothers and infants, “when not clinically indicated, cesarean delivery is a major surgical intervention that increases risk for adverse outcomes,” wrote Anna M. Frappaolo of Columbia University College of Physicians and Surgeons, New York, and colleagues.
The Healthy People 2030 campaign includes the reduction of cesarean deliveries, but trends in these procedures, especially with regard to diagnoses of labor arrest, have not been well studied, the researchers said.
In an analysis published in JAMA Network Open, the researchers reviewed delivery hospitalizations using data from the National Inpatient Sample from 2000 to 2019.
Births deemed low risk for cesarean delivery were identified by using criteria of the Society for Maternal-Fetal Medicine and additional criteria, and joinpoint regression analysis was used to estimate changes.
The researchers examined overall trends in cesarean deliveries as well as trends for three specific diagnoses: nonreassuring fetal status, labor arrest, and obstructed labor.
The final analysis included 40,517,867 deliveries; of these, 4,885,716 (12.1%) were cesarean deliveries.
Overall, cesarean deliveries in patients deemed at low risk increased from 9.7% in 2000 to 13.9% in 2009, then plateaued and decreased from 13.0% in 2012 to 11.1% in 2019. The average annual percentage change (AAPC) for cesarean delivery was 6.4% for the years from 2000 to 2005, 1.2% from 2005 to 2009, and −2.2% from 2009 to 2019.
Cesarean delivery for nonreassuring fetal status increased over the entire study period, from 3.4% in 2000 to 5.1% in 2019. By contrast, overall cesarean delivery for labor arrest increased from 3.6% in 2000 to a high of 4.8% in 2009, then decreased to 2.7% in 2019. Cesarean deliveries with a diagnosis of obstructed labor decreased from 0.9% in 2008 to 0.3% in 2019.
More specifically, cesarean deliveries for labor arrest in the active phase, latent phase, and second stage of labor increased from 1.5% to 2.1%, 1.1% to 1.5%, and 0.9% to 1.3%, respectively, from 2000 to 2009, and decreased from 2.1% to 1.7% for the active phase, from 1.5% to 1.2% for the latent phase, and from 1.2% to 0.9% for the second stage between 2010 and 2019.
Patients with increased odds of cesarean delivery were older (aged 35-39 years vs. 25-29 years, adjusted odds ratio 1.27), delivered in a hospital in the South vs. the Northeast of the United States (aOR 1.11), and were more likely to be non-Hispanic Black vs. non-Hispanic White (OR 1.23).
