Use of prophylactic negative pressure wound therapy may not be appropriate in surgical cases where women undergo a laparotomy for presumed gynecologic malignancy, according to recent research in Obstetrics & Gynecology.

“The results of our randomized trial do not support the routine use of prophylactic negative pressure wound therapy at the time of laparotomy incision closure in women who are undergoing surgery for gynecologic malignancies or in morbidly obese women who are undergoing laparotomy for benign indications,” Mario M. Leitao Jr., MD, of Memorial Sloan Kettering Cancer Center, New York, and colleagues wrote.

Dr. Leitao and colleagues randomized 663 patients, stratified by body mass index (BMI) after skin closure, to receive negative pressure wound therapy (NPWT) or standard gauze after undergoing a laparotomy for gynecological surgery between March 2016 and August 2019. Patients in the study were aged a median 61 years with a median BMI of 26 kg/m², but 32 patients with a BMI of 40 or higher who underwent a laparotomy for gynecologic surgery regardless of indication were also included in the study. Most women (80%-82%) were undergoing surgery to treat ovary, fallopian tube, or peritoneal cancer. The most common medical comorbidities in both groups were hypertension (34%-35%) and diabetes (8%-14%). Information on race of patients was not included in the baseline characteristics for the study.

In total, 505 patients were available for evaluation after surgery, which consisted of 254 patients in the NPWT group and 251 patients in the standard gauze group, with 495 patients (98%) having a malignant indication. The researchers examined the incidence of wound complication up to 30 days after surgery.

The results showed a similar rate of wound complications in the NPWT group (44 patients; 17.3%), compared with the group receiving standard gauze (41 patients; 16.3%), with an absolute risk difference between groups of 1% (90% confidence interval, –4.5 to 6.5%; P = .77). Nearly all patients who developed wound complications in both NPWT (92%) and standard gauze (95%) groups had the wound complication diagnosis occur after discharge from the hospital. Dr. Leitao and colleagues noted similarities between groups with regard to wound complications, with most patients having grade 1 complications, and said there were no instances of patients requiring surgery for complications. Among patients in the NPWT group, 33 patients developed skin blistering, compared with 3 patients in the standard gauze group (13% vs. 1.2%; P < .001). After an interim analysis consisting of 444 patients, the study was halted because of “low probability of showing a difference between the two groups at the end of the study.”

The analysis of patients with a BMI of 40 or higher showed 7 of 15 patients (47%) developed wound complications in the NPWT group and 6 of 17 patients (35%) in the standard gauze group (P = .51). In post hoc analyses, the researchers found a median BMI of 26 (range, 17-60) was significantly associated with not developing a wound complication, compared with a BMI of 32 (range, 17-56) (P < .001), and that 41% of patients with a BMI of at least 40 experienced wound complications, compared with 15% of patients with a BMI of less than 40 (P < .001). There was an independent association between developing a wound complication and increasing BMI, according to a multivariate analysis (adjusted odds ratio, 1.10; 95% CI, 1.06-1.14).
 

Applicability of results unclear for patients with higher BMI

Sarah M. Temkin, MD, a gynecologic oncologist who was not involved with the study, said in an interview that the results by Dr. Leitao and colleagues answer the question of whether patients undergoing surgery for gynecologic malignancy require NPWT, but raised questions about patient selection in the study.

“I think it’s hard to take data from this type of high-end surgical practice and apply it to the general population,” she said, who noted the median BMI of 26 for patients included in the study. A study that included only patients with a BMI of 40 or higher “would have made these results more applicable.”

The low rate of wound complications in the study could potentially be explained by patient selection, Dr. Temkin explained. She cited her own retrospective study from 2016 that showed a wound complication rate of 27.3% for patients receiving prophylactic NPWT where the BMI for the group was 41.29, compared with a complication rate of 19.7% for patients receiving standard care who had a BMI of 30.67.

“It’s hard to cross-trial compare, but that’s significantly higher than what they saw in this prospective study, and I would say that’s a difference with the patient population,” she said. “I think the question of how to reduce surgical-site infections and wound complications in the heavy patient with comorbidities is still unanswered.”

The question is important because patients with a higher BMI and medical comorbidities “still need cancer surgery and methods to reduce the morbidity of that surgery,” Dr. Temkin said. “I think this is an unmet need.”

This study was funded in part by a support grant from the National Institutes of Health/National Cancer Institute Cancer Center, and KCI/Acelity provided part of the study protocol. Nine authors reported personal and institutional relationships in the form of personal fees, grants, stock ownership, consultancies, and speaker’s bureau positions with AstraZeneca, Biom’Up, Bovie Medical, C Surgeries, CMR, ConMed, Covidien, Ethicon, GlaxoSmithKline, GRAIL, Intuitive Surgical, JNJ, Medtronic, Merck, Mylan, Olympus, Stryker/Novadaq, TransEnterix, UpToDate, and Verthermia.

Endometriosis, which affects 1 in 10 women, is one of the most common conditions that gynecologists treat. It is known to cause pain, pelvic adhesive disease, endometriotic cyst formation, and infertility. However, even more sinister, it also increases a woman’s risk for the development of epithelial ovarian cancer (known as endometriosis-associated ovarian cancer or EAOC). A woman with endometriosis has a two- to threefold increased risk of developing epithelial ovarian cancer, compared with nonaffected women.¹ This risk appears to be concentrated in the premenopausal age group, particularly the fifth decade of life. After menopause their risk of developing cancer returns to a baseline level.

EAOC classically presents as clear cell or endometrioid adenocarcinomas, rather than high-grade serous carcinomas. However, low-grade serous carcinomas are also frequently observed in this cohort.^2,3 Unlike high-grade serous carcinoma, EAOC is more likely to be diagnosed at an early stage, with the majority at stage I or II, and prognosis is better. After matching for age and stage with cases of high-grade serous carcinoma, there is improved disease-free and overall survival observed among cases of EAOC of clear cell and endometrioid histologic cell types.⁴ The phenomenon of dual primaries (synchronous endometrial and ovarian cancer) occurs more frequently in EAOC than it does in patients with nonendometriosis-related high-grade serous cancer (25% vs. 4%).

The genomics of these endometriosis-associated cancers are quite distinct. Similar to benign endometriosis implants, EAOC is associated with genomic mutations in ARID1A, PIK3CA, and PTEN, as well as progesterone resistance.^1,2 Multiple studies have shown that the adjacent eutopic endometrium carries similar gene mutations as those found in both benign endometriotic implants and EAOC.² This may explain the higher incidence (twofold) of endometrial cancer in patients with endometriosis as well as the increased incidence of dual ovarian and endometrial cancer primaries.

Just as there are multiple theories regarding the mechanism of benign endometriosis, we have theories rather than conclusions regarding the origins of EAOC. One such theory is that it develops from malignant transformation in an existing endometriotic cyst.⁵ Endometriotic cysts provide an iron-rich environment which promotes reactive oxygen species that promote carcinogenesis by inducing gene mutations and epigenetic alterations. However, if prolonged exposure to oxidative stress within endometriotic cysts were to be the cause for EAOC, we would expect to see a progressively increasing incidence of ovarian cancer over time in patients with expectantly managed cysts. However, in cases of expectant management, an initial, early, increased risk for cancer within the first 5 years is followed by a subsequent decreasing incidence over time.⁶ This early incidence spike suggests that some endometriotic cysts may have been misclassified as benign, then rapidly declare themselves as malignant during the observation period rather than a transformation into malignancy from a benign endometrioma over time.

An alternative, and favored, theory for the origins of EAOC are that endometrial cells with carcinogenic genomic alterations reflux through the fallopian tubes during menstruation and settle onto the ovarian epithelium which itself is damaged from recent ovulation thus providing an environment that is highly suitable for oncogenesis.² Genomic analyses of both the eutopic endometrium and malignant cells in patients with EAOC have shown that both tissues contain the same genomic alterations.¹ Given that menstruation, including retrograde menstruation, ends after menopause, this mechanism supports the observation that EAOC is predominantly a malignancy of premenopausal women. Additionally, salpingectomy and hysterectomy confers a protective effect on the development of EAOC, theoretically by preventing the retrograde transfer of these mutant progenitor endometrial cells. Furthermore, the factors that increase the number of menstrual cycles (such as an early age of menarche and delayed or nonchildbearing states) increases the risk for EAOC and factors that inhibit menstruation, such as oral contraceptive pill use, appear to decrease its risk.

EAOC most commonly arises in the ovary, and not in the deep endometriosis implants of adjacent pelvic structures (such as the anterior and posterior cul de sac and pelvic peritoneum). It is suggested that the ovary itself provides a uniquely favorable environment for carcinogenesis. As stated above, it is hypothesized that refluxed endometrial cells, carrying important progenitor mutations, may become trapped in the tissues of traumatized ovarian epithelium, ripe with inflammatory changes, post ovulation.² This microenvironment may promote the development of malignancy.

Given these theories and their supporting evidence, how can we attempt to reduce the incidence of this cancer for our patients with endometriosis? Despite their increased risk for ovarian and endometrial cancers, current recommendations do not support routine cancer screening in women with endometriosis.⁷ However, risk-mitigation strategies can still be pursued. Hormonal contraceptives to decrease ovulation and menstrual cycling are protective against ovarian cancer and are also helpful in mitigating the symptoms of endometriosis. While removal of endometriotic cysts may not, in and of itself, be a strategy to prevent EAOC, it is still generally recommended because these cysts are commonly a source of pain and infertility. While they do not appear to undergo malignant transformation, it can be difficult to definitively rule out an early ovarian cancer in these complex ovarian cysts, particularly as they are often associated with tumor marker abnormalities such as elevations in CA 125. Therefore, if surgical excision of an endometriotic cyst is not performed, it should be closely followed for at least 5 years to ensure it is a benign structure. If surgery is pursued and ovarian preservation is desired, removal of the fallopian tubes and uterus can help mitigate the risk for EAOC.⁸

Endometriosis is a morbid condition for many young women. In addition to causing pain and infertility it increases a woman’s risk for ovarian and endometrial cancer, particularly ovarian clear cell, endometrioid, and low-grade serous cancers and synchronous endometrial and ovarian cancers. Endometriotic cysts should be removed or closely monitored, and clinicians should discuss treatment options that minimize frequency of ovulation and menstruation events as a preventative strategy.

While removal of endometriotic cysts may not, in and of itself, be a strategy to prevent EAOC, it is still generally recommended because these cysts are commonly a source of pain and infertility. While they do not appear to undergo malignant transformation, it can be difficult to definitively rule out an early ovarian cancer in these complex ovarian cysts, particularly as they are often associated with tumor marker abnormalities such as elevations in CA 125. Therefore, if surgical excision of an endometriotic cyst is not performed, it should be closely followed for at least 5 years to ensure it is a benign structure. If surgery is pursued and ovarian preservation is desired, removal of the fallopian tubes and uterus can help mitigate the risk for EAOC.⁸

Endometriosis is a morbid condition for many young women. In addition to causing pain and infertility it increases a woman’s risk for ovarian and endometrial cancer, particularly ovarian clear cell, endometrioid, and low-grade serous cancers and synchronous endometrial and ovarian cancers. Endometriotic cysts should be removed or closely monitored, and clinicians should discuss treatment options that minimize frequency of ovulation and menstruation events as a preventative strategy.

The Food and Drug Administration on Feb. 22 updated its October 2020 guidance for manufacturers developing COVID-19 vaccines, diagnostics, and treatments in the wake of circulating SARS-CoV-2 variants.

The United States is currently facing three main variant threats, according to the Centers for Disease Control and Prevention: B.1.1.7, which originated in the United Kingdom; B.1.351 from South Africa; and the P.1 variant, which originated in Brazil.

Acting FDA Commissioner Janet Woodcock, MD, said on a telephone press briefing call Feb. 22 that the FDA has already been communicating with individual manufacturers as they assess the variants’ effect on their products, but these guidelines are issued for the sake of transparency and to welcome scientific input.
 

Tailoring may be necessary

Dr. Woodcock emphasized that, “at this time, available data suggest the FDA-authorized vaccines are effective in protecting circulating strains of SARS-CoV-2.” However, in the event the strains start to show resistance, it may be necessary to tailor the vaccine to the variant.

In that case, effectiveness of a modified vaccine should be determined by data from clinical immunogenicity studies, which would compare a recipient’s immune response with virus variants induced by the modified vaccine against the immune response to the authorized vaccine, the guidance states.

Manufacturers should also study the vaccine in both nonvaccinated people and people fully vaccinated with the authorized vaccine, according to the guidance.

Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, said on the call that the clinical immunogenicity data is needed to understand, for instance, whether a new vaccine strain is able to cover the new and old strain or whether it just covers the new strain. Information is also needed to understand whether the modified vaccine, when given to someone fully vaccinated, will still promote a positive response without introducing safety concerns.

Further discussions will be necessary to decide whether future modified vaccines may be authorized without the need for clinical studies.
 

Variants and testing

The FDA’s updated guidance for test developers, Policy for Evaluating Impact of Viral Mutations on COVID-19 Tests, includes information that test performance can be influenced by the sequence of the variant, prevalence of the variant in the population, or design of the test. For example, molecular tests designed to detect multiple SARS-CoV-2 genetic targets are less susceptible to genetic variants than tests designed to detect a single genetic target.

The FDA already issued a safety alert on Jan. 8 to caution that genetic mutations to the virus in a patient sample can potentially change the performance of a diagnostic test. The FDA identified three tests that had been granted emergency-use authorization (EUA) that are known to be affected.

However, Dr. Woodcock said on the call, “at this time the impact does not appear to be significant.”
 

Updated guidance for therapeutics

The FDA has issued new guidance on the effect of variants on monoclonal antibody treatments.

“The FDA is aware that some of the monoclonal antibodies that have been authorized are less active against some of the SARS-CoV-2 variants that have emerged,” the FDA noted in its press release. “This guidance provides recommendations on efficient approaches to the generation of ... manufacturing and controls data that could potentially support an EUA for monoclonal antibody products that may be effective against emerging variants.”

While the FDA is monitoring the effects of variants, manufacturers bear a lot of the responsibility as well.

The FDA added: “With these guidances, the FDA is encouraging developers of drugs or biological products targeting SARS-CoV-2 to continuously monitor genomic databases for emerging SARS-CoV-2 variants and evaluate phenotypically any specific variants in the product target that are becoming prevalent or could potentially impact its activity.”

Dr.Woodcock added that “we urge all Americans to continue to get tested, get their vaccines when available, and follow important heath measures such as handwashing, masking, and social distancing.”

Residual fixatives from liquid-based Pap tests and cervical swabs contain tumor-specific biomarkers for ovarian cancer, according to an analysis of proteins found in matched biospecimens from a woman with high grade serous ovarian cancer.

The findings suggest that Pap test fluid or cervical swabs could be used to detect ovarian cancer biomarker proteins to allow for earlier detection of ovarian cancer, reported Kristin L. M. Boylan, PhD, assistant director of the Ovarian Cancer Early Detection Program at the University of Minnesota, Minneapolis, and colleagues.

The investigators examined the biospecimens from a 72-year-old woman diagnosed with metastatic high-grade serous adenocarcinoma that did not encompass the cervix. The Pap test, obtained prior to surgery, was negative for malignancy, but nearly 5,000 proteins were detected in the three matched biospecimens, including more than 2,000 that were expressed in each of them.

These proteins included several known ovarian cancer biomarkers, such as CA125, HE4, and mesothelin, the investigators noted.

The findings were published online Feb. 9 in Clinical Proteomics.

“Our data demonstrate that ovarian cancer biomarkers can be detected in Pap test fluid or a cervical swab by MS-based proteomics,” the investigators wrote. “In addition to identifying multiple known biomarkers, over 2,000 proteins were detected in all three biospecimens, suggesting a potential role for novel biomarker discovery.”

Proteins from the cell-free supernatant of the patient’s liquid-based Pap test fixative were concentrated by acetone precipitation or eluted from the cervical swab, and protein was also extracted from the patient’s tumor. Analyses showed similarities in the Pap test fluid and cervical swab proteins, as well as the tumor extract.

The findings are notable, because while early detection of ovarian cancer increases survival, an adequately sensitive and specific screening tool for use in the general population is lacking, the investigators explained.

Pap test screening is widely accepted, suggesting that developing it as a screening tool for both cervical and ovarian cancers could improve testing for this “lethal but elusive disease,” they said, addding that “[W]hile our samples were from a single patient, the results are proof of concept: that Pap test fluid or cervical swabs could be used for detection of ovarian cancer biomarker proteins, and this approach warrants further investigation.”

Senior author Amy Skubitz, PhD, professor and director of the Ovarian Cancer Early Detection Program, stated in a press release that she “sees an opportunity for this method to be translated into a self-administered, at-home test, where swabs could be collected by women at home and sent to a central laboratory for analysis of proteins that would diagnose ovarian cancer.”

However, next steps include using quantitative mass spectrometry to determine if the proteins or peptides identified in this analysis are detected at higher levels in ovarian cancer Pap tests or swabs compared to controls.

“Their presence alone is not sufficient for diagnosis,” she stated.

This study was supported by the Minnesota Ovarian Cancer Alliance, the Cancurables Foundation, Charlene’s Light: A Foundation for Ovarian Cancer, and the Department of Defense Ovarian Cancer Research Program Pilot Award. The authors reported having no disclosures.

Despite slightly decreasing numbers of pregnant women hospitalized with influenza, the rate of morbidity among those who do have influenza has substantially increased from 2000 to 2015, likely due in part to an increase in comorbidities.

Maternal patients who have influenza while hospitalized for delivery are twice as likely to develop severe maternal morbidity than are those without influenza, according to findings from a new study presented at the Pregnancy Meeting, sponsored by the Society for Maternal-Fetal Medicine.

Pregnant women were also at substantially greater risk of sepsis or shock, needing mechanical ventilation, and acute respiratory distress syndrome. In fact, rates of overall severe maternal morbidity and of influenza-related complications have increased in maternal patients with influenza by more than 200% from 2000 to 2015.

“It was striking to see how the rate of delivery hospitalizations complicated by influenza has remained relatively stable with a small decline, but the rates of severe maternal morbidity were increasing and so markedly among those with influenza,” Timothy Wen, MD, MPH, a maternal-fetal medicine clinical fellow at the University of California, San Francisco, said in an interview. “The findings suggest that influenza may either be a contributor to rising rates of severe maternal morbidity or synergistically amplifying existing comorbidities to worsen outcomes,” he said during his presentation.

The increased risk of influenza complications in pregnant women became particularly apparent during the 2009-2010 H1N1 influenza pandemic. “Physiologic and immunologic changes predispose pregnant patients to higher risk for complications such as pneumonia, intensive care unit admission, and inpatient mortality,” Dr. Wen told attendees. But data have been scarce since H1N1.

The researchers conducted a cross-sectional analysis of delivery hospitalizations from 2000 to 2015 using the Nationwide Inpatient Sample, which includes about 20% of all U.S. inpatient hospitalizations from all payers. They looked at all maternal patients aged 15-54 who had a diagnosis of influenza. In looking at potential associations between influenza and morbidity, they adjusted their calculations for maternal age, payer status, median income, and race/ethnicity as well as the hospital factors of location, teaching status, and region. They also adjusted for a dozen clinical factors.

Of 62.7 million hospitalizations, 0.67% involved severe maternal mortality, including the following influenza complications:

• 0.02% with shock/sepsis.
• 0.01% needing mechanical ventilation.
• 0.04% with acute respiratory distress syndrome.

The 182,228 patients with influenza represented a rate of 29 cases per 10,000 deliveries, and 2.09% of them involved severe maternal morbidity, compared to severe maternal morbidity in just 0.66% of deliveries without influenza.

When looking specifically at rates of shock/sepsis, mechanical ventilation, and acute respiratory distress syndrome, the data revealed similar trends, with substantially higher proportions of patients with influenza experiencing these complications compared to maternal patients without influenza. For example, 0.3% of patients with influenza developed shock/sepsis whereas only 0.04% of patients without influenza did. Acute respiratory distress syndrome was similarly more common in patients with flu (0.45% vs. 0.04%), as was the need for mechanical ventilation (0.09% vs. 0.01%).

During the 15-year study period, the rate of maternal hospitalizations with influenza infections declined about 1.5%, from 30 to 24 per 10,000 deliveries. But trends with severe maternal morbidity in patients with influenza went in the other direction, increasing more than 200% over 15 years, from 100 to 342 cases of severe maternal morbidity per 10,000 patients with influenza. An increase also occurred in patients without influenza, but it was more modest, a nearly 50% increase, from 53 to 79 cases per 10,000 hospitalizations.

From year to year, severe maternal morbidity increased 5.3% annually among hospitalizations with influenza – more than twice the rate of a 2.4% annual increase among hospitalizations without influenza.

The researchers found that influenza is linked to twice the risk of severe maternal morbidity (adjusted risk ratio [aRR] = 2.08, P < .01). There were similarly higher risks with influenza of sepsis/shock (aRR = 3.23), mechanical ventilation (aRR = 6.04), and acute respiratory distress syndrome (aRR = 5.76; all P < .01).

Among the possible reasons for the increase in influenza morbidity – despite a decrease in influenza infections in this population – is the increase in the medical complexity of the patient population, Dr. Wen said.

“Patients who are getting pregnant today likely have more comorbid conditions (chronic hypertension, obesity, pregestational diabetes mellitus, etc.) than they did decades prior,” Dr. Wen said. “Clinically, it means that we have a baseline patient population at a higher risk of susceptibility for influenza and its complications.”

Maternal influenza immunization rates have meanwhile stagnated, Dr. Wen added. Influenza “is something that we know is preventable, or at least mitigated, by a vaccine,” he said. “Our results serve as a reminder for clinicians to continue counseling on the importance of influenza vaccination among pregnant patients, and even in those who are planning to become pregnant.”

He said these findings suggest the need for a low threshold for treating pregnant patients who have influenza symptoms with over-the-counter therapies or closely monitoring them.

Adetola Louis-Jacques, MD, of the University of South Florida, Tampa, found the increase in morbidity in those with flu particularly unexpected and concerning.

The researchers conducted a cross-sectional analysis of delivery hospitalizations from 2000 to 2015 using the Nationwide Inpatient Sample, which includes about 20% of all U.S. inpatient hospitalizations from all payers. They looked at all maternal patients aged 15-54 who had a diagnosis of influenza. In looking at potential associations between influenza and morbidity, they adjusted their calculations for maternal age, payer status, median income, and race/ethnicity as well as the hospital factors of location, teaching status, and region. They also adjusted for a dozen clinical factors.

Of 62.7 million hospitalizations, 0.67% involved severe maternal mortality, including the following influenza complications:

• 0.02% with shock/sepsis.
• 0.01% needing mechanical ventilation.
• 0.04% with acute respiratory distress syndrome.

The 182,228 patients with influenza represented a rate of 29 cases per 10,000 deliveries, and 2.09% of them involved severe maternal morbidity, compared to severe maternal morbidity in just 0.66% of deliveries without influenza.

When looking specifically at rates of shock/sepsis, mechanical ventilation, and acute respiratory distress syndrome, the data revealed similar trends, with substantially higher proportions of patients with influenza experiencing these complications compared to maternal patients without influenza. For example, 0.3% of patients with influenza developed shock/sepsis whereas only 0.04% of patients without influenza did. Acute respiratory distress syndrome was similarly more common in patients with flu (0.45% vs. 0.04%), as was the need for mechanical ventilation (0.09% vs. 0.01%).

During the 15-year study period, the rate of maternal hospitalizations with influenza infections declined about 1.5%, from 30 to 24 per 10,000 deliveries. But trends with severe maternal morbidity in patients with influenza went in the other direction, increasing more than 200% over 15 years, from 100 to 342 cases of severe maternal morbidity per 10,000 patients with influenza. An increase also occurred in patients without influenza, but it was more modest, a nearly 50% increase, from 53 to 79 cases per 10,000 hospitalizations.

From year to year, severe maternal morbidity increased 5.3% annually among hospitalizations with influenza – more than twice the rate of a 2.4% annual increase among hospitalizations without influenza.

The researchers found that influenza is linked to twice the risk of severe maternal morbidity (adjusted risk ratio [aRR] = 2.08, P < .01). There were similarly higher risks with influenza of sepsis/shock (aRR = 3.23), mechanical ventilation (aRR = 6.04), and acute respiratory distress syndrome (aRR = 5.76; all P < .01).

Among the possible reasons for the increase in influenza morbidity – despite a decrease in influenza infections in this population – is the increase in the medical complexity of the patient population, Dr. Wen said.

“Patients who are getting pregnant today likely have more comorbid conditions (chronic hypertension, obesity, pregestational diabetes mellitus, etc.) than they did decades prior,” Dr. Wen said. “Clinically, it means that we have a baseline patient population at a higher risk of susceptibility for influenza and its complications.”

Maternal influenza immunization rates have meanwhile stagnated, Dr. Wen added. Influenza “is something that we know is preventable, or at least mitigated, by a vaccine,” he said. “Our results serve as a reminder for clinicians to continue counseling on the importance of influenza vaccination among pregnant patients, and even in those who are planning to become pregnant.”

He said these findings suggest the need for a low threshold for treating pregnant patients who have influenza symptoms with over-the-counter therapies or closely monitoring them.

Adetola Louis-Jacques, MD, of the University of South Florida, Tampa, found the increase in morbidity in those with flu particularly unexpected and concerning.

Work load, not personal vulnerability, may be at the root of the current physician burnout crisis, a recent study has concluded.

The cutting-edge research utilized cognitive theory and work load analysis to get at the source of burnout among practitioners. The findings indicate that, although some institutions continue to emphasize personal responsibility of physicians to address the issue, it may be the amount and structure of the work itself that triggers burnout in doctors.

“We evaluated the cognitive load of a clinical workday in a national sample of U.S. physicians and its relationship with burnout and professional satisfaction,” wrote Elizabeth Harry, MD, SFHM, a hospitalist at the University of Colorado at Denver, Aurora and coauthors. The results were reported in the Joint Commission Journal on Quality and Patient Safety.

The researchers investigated whether task load correlated with burnout scores in a large national study of U.S. physicians from October 2017 to March 2018.

As the delivery of health care becomes more complex, physicians are charged with ever-increasing amount of administrative and cognitive tasks. Recent evidence indicates that this growing complexity of work is tied to a greater risk of burnout in physicians, compared with workers in other fields. Cognitive load theory, pioneered by psychologist Jonathan Sweller, identified limitations in working memory that humans depend on to carry out cognitive tasks. Cognitive load refers to the amount of working memory used, which can be reduced in the presence of external emotional or physiological stressors. While a potential link between cognitive load and burnout may seem self-evident, the correlation between the cognitive load of physicians and burnout has not been evaluated in a large-scale study until recently.

Physician task load (PTL) was measured using the National Aeronautics and Space Administration Task Load Index (NASA-TLX), a validated questionnaire frequently used to evaluate the cognitive load of work environments, including health care environments. Four domains (perception of effort and mental, physical, and temporal demands) were used to calculate the total PTL score.

Burnout was evaluated using the Emotional Exhaustion and Depersonalization scales of the Maslach Burnout Inventory, a validated tool considered the gold standard for measurement.

The survey sample consisted of physicians of all specialties and was assembled using the American Medical Association Physician Masterfile, an almost complete record of all U.S. physicians independent of AMA membership. All responses were anonymous and participation was voluntary.
 

Results

Among 30,456 physicians who received the survey, 5,197 (17.1%) responded. In total, 5,276 physicians were included in the analysis.

The median age of respondents was 53 years, and 61.8% self-identified as male. Twenty-four specialties were identified: 23.8% were from a primary care discipline and internal medicine represented the largest respondent group (12.1%).

Almost half of respondents (49.7%) worked in private practice, and 44.8% had been in practice for 21 years or longer.

Overall, 44.0% had at least one symptom of burnout, 38.8% of participants scored in the high range for emotional exhaustion, and 27.4% scored in the high range for depersonalization. The mean score in task load dimension varied by specialty.

The mean PTL score was 260.9 (standard deviation, 71.4). The specialties with the highest PTL score were emergency medicine (369.8), urology (353.7), general surgery subspecialties (343.9), internal medicine subspecialties (342.2), and radiology (341.6).

Aside from specialty, PTL scores also varied by practice setting, gender, age, number of hours worked per week, number of nights on call per week, and years in practice.

The researchers observed a dose response relationship between PTL and risk of burnout. For every 40-point (10%) reduction in PTL, there was 33% lower odds of experiencing burnout (odds ratio, 0.67; 95% confidence interval, 0.65-0.70; P < .0001). Multivariable analyses also indicated that PTL was a significant predictor of burnout, independent of practice setting, specialty, age, gender, and hours worked.
 

Organizational strategies to reduce physician burnout

Coauthors of the study, Tait D. Shanafelt, MD, professor of medicine at Stanford (Calif.) University and Colin P. West, MD, PhD, of the Mayo Clinic in Rochester, Minn., are both experts on physician well-being and are passionate about finding new ways to reduce physician distress and improving health care delivery.

“Authentic efforts to address this problem must move beyond personal resilience,” Dr. Shanafelt said in an interview. “Organizations that fail to get serious about this issue are going to be left behind and struggle in the war for talent.

“Much like our efforts to improve quality, advancing clinician well-being requires organizations to make it a priority and establish the structure, process, and leadership to promote the desired outcomes,” said Dr. Shanafelt.

One potential strategy for improvement is appointing a chief wellness officer, a dedicated individual within the health care system that leads the organizational effort, explained Dr. Shanafelt. “Over 30 vanguard institutions across the United States have already taken this step.”

Dr. West, a coauthor of the study, explained that conducting an analysis of PTL is fairly straightforward for hospitals and individual institutions. “The NASA-TLX tool is widely available, free to use, and not overly complex, and it could be used to provide insight into physician effort and mental, physical, and temporal demand levels,” he said in an interview.

“Deeper evaluations could follow to identify specific potential solutions, particularly system-level approaches to alleviate PTL,” Dr. West explained. “In the short term, such analyses and solutions would have costs, but helping physicians work more optimally and with less chronic strain from excessive task load would save far more than these costs overall.”

Dr. West also noted that physician burnout is very expensive to a health care system, and strategies to promote physician well-being would be a prudent financial decision long term for health care organizations.

Dr. Harry, lead author of the study, agreed with Dr. West, noting that “quality improvement literature has demonstrated that improvements in inefficiencies that lead to increased demand in the workplace often has the benefit of reduced cost.

“Many studies have demonstrated the risk of turnover due to burnout and the significant cost of physician turn over,” she said in an interview. “This cost avoidance is well worth the investment in improved operations to minimize unnecessary task load.”

Dr. Harry also recommended the NASA-TLX tool as a free resource for health systems and organizations. She noted that future studies will further validate the reliability of the tool.

“At the core, we need to focus on system redesign at both the micro and the macro level,” Dr. Harry said. “Each health system will need to assess inefficiencies in their work flow, while regulatory bodies need to consider the downstream task load of mandates and reporting requirements, all of which contribute to more cognitive load.”

Rochelle Walensky, MD, MPH, director of the Centers for Disease Control and Prevention, walked through a multiagency attack plan for halting the spread of three COVID-19 variants earlier this week.

As part of JAMA’s Q&A series with JAMA editor in chief Howard Bauchner, MD, Dr. Walensky referenced the blueprint she coathored with Anthony Fauci, MD, the nation’s top infectious disease expert, and Henry T. Walke, MD, MPH, of the CDC, which was published on Feb. 17 in JAMA.

In the viewpoint article, they explain that the Department of Health & Human Services has established the SARS-CoV-2 Interagency Group to improve coordination among the CDC, the National Institutes of Health, the Food and Drug Administration, the Biomedical Advanced Research and Development Authority, the Department of Agriculture, and the Department of Defense.

Dr. Walensky said the first objective is to reinforce vigilance regarding public health mitigation strategies to decrease the amount of virus that’s circulating.

As part of that strategy, she said, the CDC strongly urges against nonessential travel.

In addition, public health leaders are working on a surveillance system to better understand the SARS-CoV-2 variants. That will take ramping up genome sequencing of the SARS-CoV-2 virus and ensuring that sampling is geographically representative.

She said the CDC is partnering with state health labs to obtain about 750 samples every week and is teaming up with commercial labs and academic centers to obtain an interim target of 6,000 samples per week.

She acknowledged the United States “is not where we need to be” with sequencing but has come a long way since January. At that time, they were sequencing 250 samples every week; they are currently sequencing thousands each week.

Data analysis is another concern: “We need to be able to understand at the basic science level what the information means,” Dr. Walensky said.

Researchers aren’t sure how the variants might affect use of convalescent plasma or monoclonal antibody treatments. It is expected that 5% of persons who are vaccinated against COVID-19 will nevertheless contract the disease. Sequencing will help answer whether such persons who have been vaccinated and who subsequently contract the virus are among those 5% or whether have been infected by a variant that evades the vaccine.

Accelerating vaccine administration globally and in the United States is essential, Dr. Walensky said.

As of Feb. 17, 56 million doses had been administered in the United States.
 

Top three threats

She updated the numbers on the three biggest variant threats.

Regarding B.1.1.7, which originated in the United Kingdom, she said: “So far, we’ve had over 1,200 cases in 41 states.” She noted that the variant is likely to be about 50% more transmissible and 30% to 50% more virulent.

“So far, it looks like that strain doesn’t have any real decrease in susceptibility to our vaccines,” she said.

The strain from South Africa (B.1.351) has been found in 19 cases in the United States.

The P.1. variant, which originated in Brazil, has been identified in two cases in two states.
 

Outlook for March and April

Dr. Bauchner asked Dr. Walensky what she envisions for March and April. He noted that public optimism is high in light of the continued reductions in COVID-19 case numbers, hospitalizations, and deaths, as well as the fact that warmer weather is coming and that more vaccinations are on the horizon.

“While I really am hopeful for what could happen in March and April,” Dr. Walensky said, “I really do know that this could go bad so fast. We saw it in November. We saw it in December.”

CDC models have projected that, by March, the more transmissible B.1.1.7 strain is likely to be the dominant strain, she reiterated.

“I worry that it will be spring, and we will all have had enough,” Dr. Walensky said. She noted that some states are already relaxing mask mandates.

“Around that time, life will look and feel a little better, and the motivation for those who might be vaccine hesitant may be diminished,” she said.

Dr. Bauchner also asked her to weigh in on whether a third vaccine, from Johnson & Johnson (J&J), may soon gain FDA emergency-use authorization – and whether its lower expected efficacy rate may result in a tiered system of vaccinations, with higher-risk populations receiving the more efficacious vaccines.

Dr. Walensky said more data are needed before that question can be answered.

“It may very well be that the data point us to the best populations in which to use this vaccine,” she said.

In phase 3 data, the J&J vaccine was shown to be 72% effective in the United States for moderate to severe disease.

Dr. Walensky said it’s important to remember that the projected efficacy for that vaccine is higher than that for the flu shot as well as many other vaccines currently in use for other diseases.

She said it also has several advantages. The vaccine has less-stringent storage requirements, requires just one dose, and protects against hospitalization and death, although it’s less efficacious in protecting against contracting the disease.

“I think many people would opt to get that one if they could get it sooner,” she said.

“While I really am hopeful for what could happen in March and April,” Dr. Walensky said, “I really do know that this could go bad so fast. We saw it in November. We saw it in December.”

CDC models have projected that, by March, the more transmissible B.1.1.7 strain is likely to be the dominant strain, she reiterated.

“I worry that it will be spring, and we will all have had enough,” Dr. Walensky said. She noted that some states are already relaxing mask mandates.

“Around that time, life will look and feel a little better, and the motivation for those who might be vaccine hesitant may be diminished,” she said.

Dr. Bauchner also asked her to weigh in on whether a third vaccine, from Johnson & Johnson (J&J), may soon gain FDA emergency-use authorization – and whether its lower expected efficacy rate may result in a tiered system of vaccinations, with higher-risk populations receiving the more efficacious vaccines.

Dr. Walensky said more data are needed before that question can be answered.

“It may very well be that the data point us to the best populations in which to use this vaccine,” she said.

In phase 3 data, the J&J vaccine was shown to be 72% effective in the United States for moderate to severe disease.

Dr. Walensky said it’s important to remember that the projected efficacy for that vaccine is higher than that for the flu shot as well as many other vaccines currently in use for other diseases.

She said it also has several advantages. The vaccine has less-stringent storage requirements, requires just one dose, and protects against hospitalization and death, although it’s less efficacious in protecting against contracting the disease.

“I think many people would opt to get that one if they could get it sooner,” she said.

Rochelle Walensky, MD, MPH, director of the Centers for Disease Control and Prevention, walked through a multiagency attack plan for halting the spread of three COVID-19 variants earlier this week.

As part of JAMA’s Q&A series with JAMA editor in chief Howard Bauchner, MD, Dr. Walensky referenced the blueprint she coathored with Anthony Fauci, MD, the nation’s top infectious disease expert, and Henry T. Walke, MD, MPH, of the CDC, which was published on Feb. 17 in JAMA.

In the viewpoint article, they explain that the Department of Health & Human Services has established the SARS-CoV-2 Interagency Group to improve coordination among the CDC, the National Institutes of Health, the Food and Drug Administration, the Biomedical Advanced Research and Development Authority, the Department of Agriculture, and the Department of Defense.

Dr. Walensky said the first objective is to reinforce vigilance regarding public health mitigation strategies to decrease the amount of virus that’s circulating.

As part of that strategy, she said, the CDC strongly urges against nonessential travel.

In addition, public health leaders are working on a surveillance system to better understand the SARS-CoV-2 variants. That will take ramping up genome sequencing of the SARS-CoV-2 virus and ensuring that sampling is geographically representative.

She said the CDC is partnering with state health labs to obtain about 750 samples every week and is teaming up with commercial labs and academic centers to obtain an interim target of 6,000 samples per week.

She acknowledged the United States “is not where we need to be” with sequencing but has come a long way since January. At that time, they were sequencing 250 samples every week; they are currently sequencing thousands each week.

Data analysis is another concern: “We need to be able to understand at the basic science level what the information means,” Dr. Walensky said.

Researchers aren’t sure how the variants might affect use of convalescent plasma or monoclonal antibody treatments. It is expected that 5% of persons who are vaccinated against COVID-19 will nevertheless contract the disease. Sequencing will help answer whether such persons who have been vaccinated and who subsequently contract the virus are among those 5% or whether have been infected by a variant that evades the vaccine.

Accelerating vaccine administration globally and in the United States is essential, Dr. Walensky said.

As of Feb. 17, 56 million doses had been administered in the United States.
 

Top three threats

She updated the numbers on the three biggest variant threats.

Regarding B.1.1.7, which originated in the United Kingdom, she said: “So far, we’ve had over 1,200 cases in 41 states.” She noted that the variant is likely to be about 50% more transmissible and 30% to 50% more virulent.

“So far, it looks like that strain doesn’t have any real decrease in susceptibility to our vaccines,” she said.

The strain from South Africa (B.1.351) has been found in 19 cases in the United States.

The P.1. variant, which originated in Brazil, has been identified in two cases in two states.
 

Outlook for March and April

Dr. Bauchner asked Dr. Walensky what she envisions for March and April. He noted that public optimism is high in light of the continued reductions in COVID-19 case numbers, hospitalizations, and deaths, as well as the fact that warmer weather is coming and that more vaccinations are on the horizon.

Of four surgical procedures for breast cancer that have been determined to be of low value because they yield no meaningful clinical benefit, two continue to be utilized. In fact, the use of two of these procedures has increased in the United States, new research shows.

“This is the first study to [evaluate] all four of the low-value breast cancer procedures at the same time and try to draw some conclusions on practice patterns across facilities,” said senior author Lesly A. Dossett, MD, MPH, Center for Health Outcomes and Policy, the University of Michigan, Ann Arbor.

The two low-value procedures that have increased in use are contralateral prophylactic mastectomy for average-risk women with unilateral cancer and sentinel lymph node biopsy for clinically node-negative women aged 70 years and older with hormone receptor–positive (HR+) cancer.

“This suggests that formal efforts to reduce low value care through dissemination of guidelines, education of patients or providers, or alignment of incentives will be necessary to achieve full deimplementation,” she told this news organization.

The researchers emphasize that the providing of services that have no clinically meaningful benefit is a national epidemic, costing the United States more than $100 billion dollars annually.

These trends are notable and likely reflect a broad range of factors, commented Katharine Yao, MD, chief of the division of surgical oncology at the NorthShore University HealthSystem, Evanston, Ill.

“I think the better message here is not so much that facilities are doing too many low-value procedures but more that these procedures are still being performed, and the trends show increased rates over the years – why is that?”

“Perhaps there are other factors here we need to explore: why do these procedures persist, and why, despite the Choosing Wisely campaign, [do] they continue to increase?” she said in an interview. “Maybe there is something we can learn here about patient and physician preferences that perhaps we should be paying more attention to.”

The study was published on Feb. 3 in JAMA Surgery.

For the analysis, Dr. Dossett and her colleagues evaluated surgical data from the National Cancer Database. They examined data from more than 1,500 surgical facilities and from surgeries involving 920,256 women in the United States who were diagnosed with breast cancer between 2004 and 2016.

The team focused on four procedures that have been determined to be of low value by Choosing Wisely, a campaign of the American Board of Internal Medicine Foundation, on the basis of recommendations of the American College of Surgeons, the Society for Surgical Oncology, and the American Society for Breast Surgeons.

The results show that, for two of the four low-value procedures, use declined significantly over the study period. These two procedures were axillary lymph node dissection for limited nodal disease, for patients undergoing lumpectomy and radiotherapy, and lumpectomy re-excision for patients whose surgical margins were close but were negative for invasive cancer.

Axillary lymph node dissection declined from 63% in 2004 to 14% in 2016. The steepest reduction was seen soon after data from the Z0011 study were published in 2010. The rates for this procedure halved in the following year, from 62% in 2010 to 31% in 2011 (P < .001).

Likewise, reoperation rates after lumpectomy dropped from 19% in 2004 to 15% in 2016. The sharpest decline, from 18% in 2013 to 16% in 2014, corresponded to the publishing of the SSO/ASTRO consensus statement, which designated a negative margin as having “no tumor on ink.”

Two of the four low-value procedures increased in use during the study period.

Rates of contralateral prophylactic mastectomy increased nearly 2.5-fold among women with unilateral breast cancer undergoing mastectomy, from 11% in 2004 to 26% in 2016, despite SSO guidelines issued in 2007 recommending that the procedure not be used for women at average risk.

In addition, rates of sentinel lymph node biopsy among women aged 70 years and older with clinically node-negative HR+ breast cancer increased from 78% in 2004 to 87% in 2012. There was no significant decline in the use of this procedure, even after the CALGB 9343 trial from the Cancer and Leukemia Group B showed no survival benefit in 2013.
 

Patterns at hospitals vary

The authors of the study also examined hospital factors, which can heavily influence choice of procedure.

These results showed that the greatest reductions of the low-value breast cancer procedures occurred at academic research programs and high-volume surgical facilities. Elsewhere, the rates varied widely.

Interfacility rates of axillary lymph node dissection ranged from 7% to 47%; lumpectomy reoperation rates ranged from 3% to 62%; contralateral prophylactic mastectomy rates ranged from 9% to 67%; and sentinel lymph node biopsy rates ranged from 25% to 97%.

Being an outlier for use of one procedure did not necessarily translate to nonconformity for others. Factors such as a hospital’s volume of breast cancer cases or the type of facility did not appear to influence rates of axillary lymph node dissection or lumpectomy reoperation.

However, the rates of contralateral prophylactic mastectomy were significantly higher in high-volume centers and integrated network cancer programs, compared with community cancer programs (23% vs. 2%; P < .001).

Dr. Dossett said the lack of consistency was somewhat unexpected.

“We expected we would find some facilities were constantly good or bad at deimplementation or that there would be stronger associations between certain facility characteristics and performance,” she said. “That really wasn’t the case, and most facilities had mixed performance.”
 

Evidence may or may not influence trends

The authors speculate on why the low-value designation is in some cases being ignored.

The evidence regarding the risk for lymphedema related to axillary lymph node dissection procedure appears to have helped reduce its use, they note.

However, surgeons have been much less convinced of benefits in omitting sentinel lymph node biopsy, either because they are unfamiliar with the recommendations to avoid the procedure, or they may feel the procedure adds only minimal time and risk to a patient’s operation, the authors explain.

Patients may be convinced to opt to omit sentinel lymph node biopsy if they are properly counseled regarding the risks and benefits of the procedure, Dr. Dossett commented.

Dr. Yao added that, for elderly patients, age can play an important role in sentinel node biopsy.

“Patients’ life expectancy has increased over the years, and node status may impact adjuvant therapy decisions for these patients, even chemotherapy decisions,” she said.

Pressure to continue to perform contralateral prophylactic mastectomy is believed to be significantly patient driven, Dr. Dossett noted.

“I ultimately think the best way to reduce contralateral prophylactic mastectomy is to encourage women with small cancers to undergo breast-conserving surgery, i.e., lumpectomy, instead of mastectomy,” she explained.

“Once the decision for mastectomy is made, there is often a great deal of momentum towards a contralateral prophylactic mastectomy.”

“Contralateral prophylactic mastectomy is a personal preference that many surgeons are willing to do for their patients,” Dr. Yao explained.

“Although no survival benefit has been demonstrated for this procedure, patients find many other benefits that have nothing to do with survival.”

The authors and Dr. Yao have disclosed no relevant financial relationships.

While the likelihood of a cesarean delivery usually drops as maternal education level increases, the disparities seen in cesarean rates between White and Black or Hispanic women actually increase with more maternal education, according to findings from a new study presented at the Pregnancy Meeting sponsored by the Society for Maternal-Fetal Medicine.

Typically, higher maternal education is associated with a lower likelihood of cesarean delivery, but this protective effect is much smaller for Black women and nonexistent for Hispanic women, leading to bigger gaps between these groups and White women, found Yael Eliner, MD, an ob.gyn. residency applicant at Boston University who conducted this research with her colleagues in the ob.gyn. department at Lenox Hill Hospital, New York, and Hofstra University, Hempstead, N.Y..

Researchers have previously identified racial and ethnic disparities in a wide range of maternal outcomes, including mortality, overall morbidity, preterm birth, low birth weight, fetal growth restriction, hypertensive disorders of pregnancy, diabetes, and cesarean deliveries. But the researchers wanted to know if the usual protective effects seen for cesarean deliveries existed in the racial and ethnic groups with these disparities. Past studies have already found that the protective effect of maternal education is greater for White women than Black women with infant mortality and overall self-rated health.

The researchers conducted a retrospective analysis of all low-risk nulliparous, term, singleton, vertex live births to U.S. residents from 2016 to 2019 by using the natality database of the Centers for Disease Control and Prevention. They looked only at women who were non-Hispanic White, non-Hispanic Black, non-Hispanic Asian, and Hispanic women. They excluded women with pregestational and gestational diabetes, chronic hypertension, and hypertensive disorders of pregnancy.

Maternal education levels were stratified into those without a high school diploma, high school graduates (including those with some college credit), college graduates, and those with advanced degrees. The total population included 2,969,207 mothers with a 23.4% cesarean delivery rate.

Before considering education or other potential confounders, the cesarean delivery rate was 27.4% in Black women and 25.6% in Asian women, compared with 22.4% in White women and 23% in Hispanic women (P < .001).

Among those with less than a high school education, Black (20.9%), Asian (23.1%), and Hispanic (17.9% cesarean delivery prevalence was greater than that among White women (17.2%) (P < .001). The same was true among those with a high school education (with or without some college): 22% of White women in this group had cesarean deliveries compared with 26.3% of Black women, 26.3% of Asian women, and 22.5% of Hispanic women (P < .001).

At higher levels of education, the disparities not only persisted but actually increased.

The prevalence of cesarean deliveries was 23% in White college graduates, compared with 32.5% of Black college graduates, 26.3% of Asian college graduates, and 27.7% of Hispanic college graduates (P < .001). Similarly, in those with an advanced degree, the prevalence of cesarean deliveries in their population set was 23.6% of Whites, 36.3% of Blacks, 26.1% of Asians, and 30.1% of Hispanics (P < .001).

After adjusting for maternal education as well as age, prepregnancy body mass index, weight gain during pregnancy, insurance type, and neonatal birth weight, the researchers still found substantial disparities in cesarean delivery rates. Black women had 1.54 times greater odds of cesarean delivery than White women (P < .001). Similarly, the odds were 1.45 times greater for Asian women and 1.24 times greater for Hispanic women (P < .001).

Controlling for race, ethnicity, and the other confounders, women with less than a high school education or a high school diploma had similar likelihoods of cesarean delivery. The likelihood of a cesarean delivery was slightly reduced for women with a college degree (odds ratio, 0.93) or advanced degree (OR, 0.88). But this protective effect did not dampen racial/ethnic disparities. In fact, even greater disparities were seen at higher levels of education.

“At each level of education, all the racial/ethnic groups had significantly higher odds of a cesarean delivery than White women,” Dr. Eliner said. “Additionally, the racial/ethnic disparity in cesarean delivery rates increased with increasing level of education, and we specifically see a meaningful jump in the odds ratio at the college graduate level.”

She pointed out that the OR for cesarean delivery in Black women was 1.4 times greater than White women in the group with less than a high school education and 1.44 times greater in those with high school diplomas. Then it jumped to 1.69 in the college graduates group and 1.7 in the advanced degree group.

Higher maternal education was associated with a lower likelihood of cesarean delivery in White women and Asian women. White women with advanced degrees were 17% less likely to have a cesarean than White women with less than a high school education, and the respective reduction in risk was 19% for Asian women.

In Black women, however, education has a much smaller protective effect: An advanced degree reduced the odds of a cesarean delivery by only 7% and no significant difference showed up between high school graduates and college graduates, Dr. Eliner reported.

In Hispanic women, no protective effect showed up, and the odds of a cesarean delivery actually increased slightly in high school and college graduates above those with less than a high school education.

Dr. Eliner discussed a couple possible reasons for a less protective effect from maternal education in Black and Hispanic groups, including higher levels of chronic stress found in past research among racial/ethnic minorities with higher levels of education.

“The impact of racism as a chronic stressor and its association with adverse obstetric and prenatal outcomes is an emerging theme in health disparity research and is yet to be fully understood,” Dr. Eliner said in an interview. “Nonetheless, there is some evidence suggesting that racial/ethnic minorities with higher levels of education suffer from higher levels of stress.”

Implicit and explicit interpersonal bias and institutional racism may also play a role in the disparities, she said, and these factors may disproportionately affect the quality of care for more educated women. She also suggested that White women may be more comfortable advocating for their care.

“While less educated women from all racial/ethnic groups may lack the self-advocacy skills to discuss their labor course, educated White women may be more confident than women from educated minority groups,” Dr. Eliner told attendees. “They may therefore be better equipped to discuss the need for a cesarean delivery with their provider.”

Dr. Eliner elaborated on this: “Given the historical and current disparities of the health care system, women in racial/ethnic minorities may potentially be guarded in their interaction with medical professionals, with a reduced trust in the health care system, and may thus not feel empowered to advocate for themselves in this setting,” she said.
