Serum biomarkers of inflammation may help identify which athletes will take longer to recover after a sport-related concussion, research suggests. Levels of interleukin-6 (IL-6) and IL-1 receptor antagonist (IL-1RA) are significantly elevated 6 hours after concussion, and higher IL-6 levels are associated with slower recovery, according to a study of 41 high school and college football players with concussion. The findings were published online ahead of print July 3 in Neurology.

“With so many people sustaining concussions and a sizeable number of them having prolonged symptoms and recovery, any tools we can develop to help determine who would be at greater risk of problems would be very beneficial,” said study author Timothy B. Meier, PhD, assistant professor of neurosurgery at the Medical College of Wisconsin in Milwaukee, in a news release. “These results are a crucial first step.”

Symptoms of sport-related concussion typically resolve within 1-2 weeks but may last longer. Although prior studies have focused on biomarkers that are specific to brain injury, nonspecific inflammatory markers also may hold promise in predicting recovery after a mild traumatic brain injury, the authors said.

To examine whether acute elevations in serum inflammatory markers predict symptom recovery following sport-related concussion, Dr. Meier and his research colleagues enrolled 857 high school and college football players into a prospective cohort study. They included in their analyses 41 concussed athletes and 43 matched control athletes with an average age of 18 years. None of the concussed athletes lost consciousness, two had posttraumatic amnesia, and one had retrograde amnesia. The concussed athletes had a mean symptom duration of 8.86 days.

The researchers measured serum levels of IL-6, IL-1RA, IL-1 beta, IL-10, tumor necrosis factor, C-reactive protein, and interferon-gamma and recorded Sport Concussion Assessment Tool, 3rd edition, symptom severity scores.

Participants with concussion underwent testing at the start of the season, within 6 hours of injury, 24-48 hours after injury, and at 8, 15, and 45 days after injury. Control athletes underwent testing at similar times.

Among athletes with concussion, IL-1RA and IL-6 were elevated at 6 hours, compared with all other postinjury visits and with controls. IL-6 and IL-1RA significantly discriminated concussed from control athletes at 6 hours postconcussion with an area under the receiver operating characteristic curve of 0.79 for IL-6 and 0.79 for IL-1RA. Furthermore, IL-6 levels at 6 hours significantly correlated with symptom duration, “with a 1-unit increase in natural log-transformed IL-6 associated with 39% lower hazard of symptom recovery,” the researchers reported.

The extent to which these results generalize to females, youth athletes, or athletes who develop postconcussion syndrome is unclear, and larger studies may be needed to adequately assess inflammatory markers as clinical biomarkers of sport-related concussion, the authors noted.

“Eventually, these results may help us better understand the relationship between injury and inflammation and potentially lead to new treatments,” Dr. Meier said.

Selinexor (Xpovio) has been approved for use in combination with dexamethasone for the treatment of select adult patients with relapsed refractory multiple myeloma (RRMM), the Food and Drug Administration announced in a statement.

The oral therapy was approved for patients who have received at least four prior therapies and whose disease is resistant to several other forms of treatment, including at least two proteasome inhibitors, at least two immunomodulatory agents, and an anti-CD38 monoclonal antibody, according to the FDA.

The approval provides a “treatment option for patients with multiple myeloma with no (other) available therapy,” said Richard Pazdur, MD, director of the FDA Oncology Center of Excellence and acting director of the Office of Hematology and Oncology Products in the FDA Center for Drug Evaluation and Research.

The approval was based on a study that included 83 patients with RRMM who had an overall response rate of 25.3% to Xpovio in combination with dexamethasone.

“The median time to first response was 4 weeks, with a range of 1-10 weeks. The median duration of response was 3.8 months. The efficacy evaluation was supported by additional information from an ongoing, randomized trial in patients with multiple myeloma,” according to the statement.

Common side effects seen in patients taking Xpovio in combination with dexamethasone include leukopenia, neutropenia, thrombocytopenia, and anemia. Patients also reported vomiting, nausea, fatigue, diarrhea, fever, decreased appetite and weight, constipation, upper respiratory tract infections, and hyponatremia.

Patients taking Xpovio should be monitored for low blood counts, platelets, and sodium levels, and should avoid other medications that may cause dizziness or confusion. Patients’ hydration status, blood counts, and other medications should be optimized to avoid dizziness or confusion. Females of reproductive age and males with a female partner of reproductive potential must use effective contraception during treatment with Xpovio. Women who are pregnant or breastfeeding should not take Xpovio.

Xpovio must be dispensed with a patient Medication Guide that describes important information about the drug’s uses and risks.

Xpovio in combination with dexamethasone was granted accelerated approval, and further clinical trials are required to verify and describe the drug’s clinical benefit.

The FDA granted the approval of Xpovio to Karyopharm Therapeutics.

CASE Low-risk maternity patient wants fewer prenatal visits

A recently pregnant patient asks her obstetrician if she can schedule fewer prenatal visits given that she is at low risk, wants to minimize missing work, and lives an hour away from the clinic office. Her physician tells her that she needs the standard 13 to 15 visits to have a healthy pregnancy.

Obstetric care in the United States largely remains a “one-size fits all” approach despite compelling data that fewer visits for low-risk women are medically acceptable and may be more cost-effective.

Prenatal care: One size does not fit all

With nearly 4 million births annually in the United States, prenatal care is one of the most widely used preventive health care strategies.^1,2 The ideal method for providing prenatal care, however, remains controversial. At the inception of early 20th century prenatal care in the United States, preventive strategies focused in part on eclampsia-related maternal morbidity and mortality, which in turn informed the content and frequency of prenatal visits.² Despite the dramatic changes in medical practice over the last 100 years, the basic timing and quantity of prenatal care has not changed substantively.

The lack of change is not because we have not explored other models of prenatal care and sought to introduce evidence-based change. Several studies have assessed the impact of reduced prenatal care visits for low-risk women.^3-7 Systematic reviews evaluated 7 randomized trials, with more than 60,000 women enrolled, of prenatal care models with a reduced number of planned antenatal visits (4 to 9 visits vs the traditional 13 to 15 visits).^3,8 There were no demonstrable differences in maternal or perinatal morbidity or mortality, particularly in higher resource settings.

Despite strong safety data and the potential cost-effectiveness of a reduced schedule of prenatal visits, US prenatal care practices generally continue to have a one-size-fits-all approach. Several organizations, however, have called for a change in practice.

Endorsing a reduced number of prenatal visits for low-risk women, the US Department of Health and Human Services Expert Panel on Prenatal Care issued a report in 1989 that stated “the specific content and timing of prenatal visits, contacts, and education should vary depending on the risk status of the pregnant woman and her fetus.”⁹ Consistent with that recommendation, the American Academy of Pediatrics and the American College of Obstetricians and Gynecologists (ACOG) jointly published guidelines that recommend a system of goal-oriented antenatal visits at specific gestational ages and that support a reduced schedule of prenatal visits, compared with traditional models, for low-risk, parous women.¹⁰ The World Health Organization also published recommendations for an 8 “contact” prenatal care system to reduce perinatal mortality and improve women’s prenatal experience.¹¹

Is obstetric dogma the reason for lack of change?

Concerns about patient satisfaction may play a role in limiting the use of a reduced prenatal care visit model. In trials that evaluated a model of reduced prenatal care visits, women were less satisfied with a reduced visit schedule and the gap between provider contacts.^3,8 Anecdotally, providers have expressed concerns about perceived liability. Most compelling, perhaps, is the idea that the traditional prenatal schedule has become obstetric dogma.

Continue to: Consciously or unconsciously, clinicians may feel...

Consciously or unconsciously, clinicians may feel uncomfortable diverging from a schedule of visits that is firmly entrenched in obstetric practice. Continuing the status quo is easier than restructuring prenatal care practice. Ultimately, a paradigm shift may be required to broadly adopt a model of fewer prenatal visits for low-risk pregnancies.¹² With these issues propelling the historic patterns of prenatal care, it is easy to see why we have not yet changed despite convincing reasons to do so.

In this article, we detail the reduced-visit prenatal care models developed at 3 institutions and how they incorporate use of today’s technology.

Approach #1: University of Utah Virtual Prenatal Care Program

The University of Utah Virtual Prenatal Care Program was conceived as a “baby step” toward developing a model of fewer total prenatal visits. Virtual visits were intended to reduce the number of prenatal face-to-face visits while maintaining the same total number of visits. Since large clinical trials had established the safety of reduced visits, the primary objectives were to retain patient satisfaction and to facilitate provider adoption.

Would women be satisfied with remote prenatal care? A prospective randomized controlled trial was designed in which 200 women were assigned to receive either a combination of telemedicine and 5 scheduled in-clinic prenatal visits (remote care group) or traditional in-clinic prenatal care (usual care group). Low-risk multigravida pregnant women who were between 6 0/7 and 16 0/7 weeks’ gestation were enrolled. The primary outcome was patient satisfaction.

The face-to-face visits were goal oriented, with scheduled physical examination, laboratory tests, or ultrasonography, and were conducted by the patient’s established obstetric provider (physician or nurse midwife) to maintain continuity of care. The remote care group self-collected measurements for weight, blood pressure, and fetal heart rate by handheld Doppler device prior to each telemedicine visit and entered the information into the electronic medical record. The purpose of the self-collected data was patient engagement and satisfaction, as well as increased provider comfort with the change in prenatal care schedule, rather than medical necessity.

The primary outcome of overall patient satisfaction with prenatal care was ascertained by questionnaire after delivery. The sample size calculation of 200 patients was based on noninferiority testing, and analysis was by intent-to-treat. The details of the trial are pending publication.

As expected, the remote care group had significantly fewer in-clinic prenatal care visits compared with the usual care group (7.2 vs 11.3 visits); the total number of prenatal visits was not different between groups. Overall satisfaction with prenatal care was very high in both the remote care and the usual care group (100% vs 97%).

The virtual prenatal care model for low-risk pregnancies, consisting of a novel remote monitoring strategy and a reduced number of in-clinic visits, was not associated with lower patient satisfaction compared with traditional care.

New care strategy gives patients a choice. The success of this clinical trial has led to its programmatic adoption at the University of Utah, and low-risk women currently are offered a choice between participating in the Virtual Prenatal Care Program or receiving traditional prenatal care. The University of Utah is moving on from the one-size-fits-all approach to adopt new strategies that provide personalized evidence-based prenatal care at the lowest cost, while retaining high patient satisfaction. Formal cost-effectiveness analyses are underway.

Approach #2: Mayo Clinic OB Nest

In 2011, the Mayo Clinic Obstetric Division partnered with 2 other Mayo Clinic divisions, the Center for Innovation and the Center for the Science of Health Care Delivery, to redesign prenatal care for low-risk expectant mothers.Pregnant women and their obstetric health care teams (including obstetricians, certified nurse midwives, registered nurses, and clinical support staff) were convened to develop a novel model of prenatal care.⁴ The goal of this collaboration centered on:

• creating an evidence-driven prenatal care model for low-risk expectant women designed by relevant stakeholders
• focusing on meeting the on-demand needs of expectant mothers
• integrating innovative 21st century technology, and
• reducing the burden of prescheduled, low-value office visits.

Exploratory efforts to develop a novel care program. Based on feedback from the collaboration and guided by these goals, 141 expectant mothers participated in 19 different experiments, enabling the health care team to understand the impact of changing various components of prenatal care.

The experiments included integration of home monitoring (home fetal Doppler devices, drop-in fetal Doppler stations, home blood pressure monitoring devices), technology-enhanced communication with obstetric team members (video chats, tummy photos, virtual prenatal clinic appointments, proactive calls), and social media engagement (secure online prenatal care community).

Recommendations for the final components of OB Nest were based on feasibility and the potential impact on care. The recommendations included decreasing scheduled clinic appointments from 14 to 8, providing home monitoring devices to measure maternal blood pressure and fetal heart rate, establishing OB Nest virtual connected care visits with a registered nurse, and offering a secure online community of expectant mothers.

Trial assessed program’s efficacy, safety, satisfaction. A mixed-methods randomized controlled trial subsequently was conducted to evaluate the components of OB Nest.⁶ The trial included 300 pregnant women who were randomly assigned to standard prenatal care as recommended by ACOG or to OB Nest care.

OB Nest care consisted of 8 scheduled clinic appointments, 6 planned virtual (phone or online) connected care visits with a registered nurse dedicated to OB Nest, home monitoring of blood pressure (with a home digital sphygmomanometer) and fetal heart rate, and access to an online prenatal care community designated for OB Nest participants.

While publication of the trial results currently is pending, the OB Nest program appears to safely and effectively decrease the number of scheduled prenatal care visits for low-risk expectant mothers while improving the overall patient experience. OB Nest care now is offered as one of several options for low-risk expectant mothers at Mayo Clinic.

Additional avenues of study. Studies evaluating the impact of OB Nest in various nonacademic settings are now underway. Also under review is the potential cost savings of OB Nest as related to the productive lives of expectant mothers, while prenatal care safety is maintained.

The focus shift from a sick to a wellness perspective, stakeholder inclusion in the program design, and the integration of home monitoring tools are all major contributing factors to the success of OB Nest.

Approach #3: Prisma Health utilizes mobile app technology

A third approach to reducing unnecessary visits for routine maternity care is to employ mobile app technology. Technology companies have developed app platforms for providers to use to educate and connect with patients; such apps reduce the number of routine obstetric office visits while maintaining patient satisfaction.

One group’s app experience. In a pilot study at a Prisma Health practice (South Carolina), 100 patients were placed on a reduced appointment schedule of 9 prenatal visits; the women self-monitored their weight gain and blood pressure using a remote monitoring system via an app called Babyscripts.⁷ Patient feedback was collected, with 45 of 100 patients responding.

Ninety-five percent of patients were satisfied with the mobile app, 94% reported positivity around pregnancy readiness, 90% were satisfied with their health care team, and 89% were happy with remote monitoring. Patients visited the app 3 times per week on average, and the top categories of interest were travel, exercise, genetics, and eating right.

One patient using the Babyscripts mobile health app and schedule optimization platform commented, “I am on my second pregnancy and wish this had been available for the first! The app is easy to use and I love seeing my weight on a graph. And I very much like the quality of the cuff” (personal data generated from Babyscripts).

In with the new

As clinicians strive to provide more patient-centered care, offering expectant families more than one way to receive their prenatal care is appropriate. Beyond the traditional 14-visit care model, we should offer use of novel options like mobile health apps, which improve the patient experience while decreasing the cost of care by reducing unnecessary visits.¹² Note also that reducing visits for low-risk mothers opens space in the provider schedule for patients who need services more quickly.

Benefits for postpartum care. Traditionally, clinicians see the low-risk patient for a single follow-up appointment at 6 weeks postpartum. However, the World Health Organization recommends evaluating women at 3 days, 1 to 2 weeks, and 6 weeks postpartum.¹³ Further, the National Institute for Health and Care Excellence guidance recommends screening all women for resolution of postpartum blues at 10 to 14 days.¹⁴

ACOG also has made recommendations on optimizing postpartum care. In a committee opinion, ACOG recommends that all women have contact with their provider within the first 3 weeks postpartum.¹⁵ Recognizing that such an in-person visit may be difficult, ACOG has endorsed communication via text messaging, app-based support, and remote monitoring.¹⁵ An app such as Babyscripts would fill this need conveniently for both patient and provider.

In 2019, patients want choice. As maternity care providers, we should be open to considering novel, evidence-based options that may provide more cost-effective obstetric care.

Approach #2: Mayo Clinic OB Nest

In 2011, the Mayo Clinic Obstetric Division partnered with 2 other Mayo Clinic divisions, the Center for Innovation and the Center for the Science of Health Care Delivery, to redesign prenatal care for low-risk expectant mothers.Pregnant women and their obstetric health care teams (including obstetricians, certified nurse midwives, registered nurses, and clinical support staff) were convened to develop a novel model of prenatal care.⁴ The goal of this collaboration centered on:

• creating an evidence-driven prenatal care model for low-risk expectant women designed by relevant stakeholders
• focusing on meeting the on-demand needs of expectant mothers
• integrating innovative 21st century technology, and
• reducing the burden of prescheduled, low-value office visits.

Exploratory efforts to develop a novel care program. Based on feedback from the collaboration and guided by these goals, 141 expectant mothers participated in 19 different experiments, enabling the health care team to understand the impact of changing various components of prenatal care.

The experiments included integration of home monitoring (home fetal Doppler devices, drop-in fetal Doppler stations, home blood pressure monitoring devices), technology-enhanced communication with obstetric team members (video chats, tummy photos, virtual prenatal clinic appointments, proactive calls), and social media engagement (secure online prenatal care community).

Recommendations for the final components of OB Nest were based on feasibility and the potential impact on care. The recommendations included decreasing scheduled clinic appointments from 14 to 8, providing home monitoring devices to measure maternal blood pressure and fetal heart rate, establishing OB Nest virtual connected care visits with a registered nurse, and offering a secure online community of expectant mothers.

Trial assessed program’s efficacy, safety, satisfaction. A mixed-methods randomized controlled trial subsequently was conducted to evaluate the components of OB Nest.⁶ The trial included 300 pregnant women who were randomly assigned to standard prenatal care as recommended by ACOG or to OB Nest care.

OB Nest care consisted of 8 scheduled clinic appointments, 6 planned virtual (phone or online) connected care visits with a registered nurse dedicated to OB Nest, home monitoring of blood pressure (with a home digital sphygmomanometer) and fetal heart rate, and access to an online prenatal care community designated for OB Nest participants.

While publication of the trial results currently is pending, the OB Nest program appears to safely and effectively decrease the number of scheduled prenatal care visits for low-risk expectant mothers while improving the overall patient experience. OB Nest care now is offered as one of several options for low-risk expectant mothers at Mayo Clinic.

Additional avenues of study. Studies evaluating the impact of OB Nest in various nonacademic settings are now underway. Also under review is the potential cost savings of OB Nest as related to the productive lives of expectant mothers, while prenatal care safety is maintained.

The focus shift from a sick to a wellness perspective, stakeholder inclusion in the program design, and the integration of home monitoring tools are all major contributing factors to the success of OB Nest.

Approach #3: Prisma Health utilizes mobile app technology

A third approach to reducing unnecessary visits for routine maternity care is to employ mobile app technology. Technology companies have developed app platforms for providers to use to educate and connect with patients; such apps reduce the number of routine obstetric office visits while maintaining patient satisfaction.

One group’s app experience. In a pilot study at a Prisma Health practice (South Carolina), 100 patients were placed on a reduced appointment schedule of 9 prenatal visits; the women self-monitored their weight gain and blood pressure using a remote monitoring system via an app called Babyscripts.⁷ Patient feedback was collected, with 45 of 100 patients responding.

Ninety-five percent of patients were satisfied with the mobile app, 94% reported positivity around pregnancy readiness, 90% were satisfied with their health care team, and 89% were happy with remote monitoring. Patients visited the app 3 times per week on average, and the top categories of interest were travel, exercise, genetics, and eating right.

One patient using the Babyscripts mobile health app and schedule optimization platform commented, “I am on my second pregnancy and wish this had been available for the first! The app is easy to use and I love seeing my weight on a graph. And I very much like the quality of the cuff” (personal data generated from Babyscripts).

In with the new

As clinicians strive to provide more patient-centered care, offering expectant families more than one way to receive their prenatal care is appropriate. Beyond the traditional 14-visit care model, we should offer use of novel options like mobile health apps, which improve the patient experience while decreasing the cost of care by reducing unnecessary visits.¹² Note also that reducing visits for low-risk mothers opens space in the provider schedule for patients who need services more quickly.

Benefits for postpartum care. Traditionally, clinicians see the low-risk patient for a single follow-up appointment at 6 weeks postpartum. However, the World Health Organization recommends evaluating women at 3 days, 1 to 2 weeks, and 6 weeks postpartum.¹³ Further, the National Institute for Health and Care Excellence guidance recommends screening all women for resolution of postpartum blues at 10 to 14 days.¹⁴

ACOG also has made recommendations on optimizing postpartum care. In a committee opinion, ACOG recommends that all women have contact with their provider within the first 3 weeks postpartum.¹⁵ Recognizing that such an in-person visit may be difficult, ACOG has endorsed communication via text messaging, app-based support, and remote monitoring.¹⁵ An app such as Babyscripts would fill this need conveniently for both patient and provider.

In 2019, patients want choice. As maternity care providers, we should be open to considering novel, evidence-based options that may provide more cost-effective obstetric care.

CASE Low-risk maternity patient wants fewer prenatal visits

A recently pregnant patient asks her obstetrician if she can schedule fewer prenatal visits given that she is at low risk, wants to minimize missing work, and lives an hour away from the clinic office. Her physician tells her that she needs the standard 13 to 15 visits to have a healthy pregnancy.

Obstetric care in the United States largely remains a “one-size fits all” approach despite compelling data that fewer visits for low-risk women are medically acceptable and may be more cost-effective.

Prenatal care: One size does not fit all

With nearly 4 million births annually in the United States, prenatal care is one of the most widely used preventive health care strategies.^1,2 The ideal method for providing prenatal care, however, remains controversial. At the inception of early 20th century prenatal care in the United States, preventive strategies focused in part on eclampsia-related maternal morbidity and mortality, which in turn informed the content and frequency of prenatal visits.² Despite the dramatic changes in medical practice over the last 100 years, the basic timing and quantity of prenatal care has not changed substantively.

The lack of change is not because we have not explored other models of prenatal care and sought to introduce evidence-based change. Several studies have assessed the impact of reduced prenatal care visits for low-risk women.^3-7 Systematic reviews evaluated 7 randomized trials, with more than 60,000 women enrolled, of prenatal care models with a reduced number of planned antenatal visits (4 to 9 visits vs the traditional 13 to 15 visits).^3,8 There were no demonstrable differences in maternal or perinatal morbidity or mortality, particularly in higher resource settings.

Despite strong safety data and the potential cost-effectiveness of a reduced schedule of prenatal visits, US prenatal care practices generally continue to have a one-size-fits-all approach. Several organizations, however, have called for a change in practice.

Endorsing a reduced number of prenatal visits for low-risk women, the US Department of Health and Human Services Expert Panel on Prenatal Care issued a report in 1989 that stated “the specific content and timing of prenatal visits, contacts, and education should vary depending on the risk status of the pregnant woman and her fetus.”⁹ Consistent with that recommendation, the American Academy of Pediatrics and the American College of Obstetricians and Gynecologists (ACOG) jointly published guidelines that recommend a system of goal-oriented antenatal visits at specific gestational ages and that support a reduced schedule of prenatal visits, compared with traditional models, for low-risk, parous women.¹⁰ The World Health Organization also published recommendations for an 8 “contact” prenatal care system to reduce perinatal mortality and improve women’s prenatal experience.¹¹

Is obstetric dogma the reason for lack of change?

Concerns about patient satisfaction may play a role in limiting the use of a reduced prenatal care visit model. In trials that evaluated a model of reduced prenatal care visits, women were less satisfied with a reduced visit schedule and the gap between provider contacts.^3,8 Anecdotally, providers have expressed concerns about perceived liability. Most compelling, perhaps, is the idea that the traditional prenatal schedule has become obstetric dogma.

Continue to: Consciously or unconsciously, clinicians may feel...

Consciously or unconsciously, clinicians may feel uncomfortable diverging from a schedule of visits that is firmly entrenched in obstetric practice. Continuing the status quo is easier than restructuring prenatal care practice. Ultimately, a paradigm shift may be required to broadly adopt a model of fewer prenatal visits for low-risk pregnancies.¹² With these issues propelling the historic patterns of prenatal care, it is easy to see why we have not yet changed despite convincing reasons to do so.

In this article, we detail the reduced-visit prenatal care models developed at 3 institutions and how they incorporate use of today’s technology.

Approach #1: University of Utah Virtual Prenatal Care Program

The University of Utah Virtual Prenatal Care Program was conceived as a “baby step” toward developing a model of fewer total prenatal visits. Virtual visits were intended to reduce the number of prenatal face-to-face visits while maintaining the same total number of visits. Since large clinical trials had established the safety of reduced visits, the primary objectives were to retain patient satisfaction and to facilitate provider adoption.

Would women be satisfied with remote prenatal care? A prospective randomized controlled trial was designed in which 200 women were assigned to receive either a combination of telemedicine and 5 scheduled in-clinic prenatal visits (remote care group) or traditional in-clinic prenatal care (usual care group). Low-risk multigravida pregnant women who were between 6 0/7 and 16 0/7 weeks’ gestation were enrolled. The primary outcome was patient satisfaction.

The face-to-face visits were goal oriented, with scheduled physical examination, laboratory tests, or ultrasonography, and were conducted by the patient’s established obstetric provider (physician or nurse midwife) to maintain continuity of care. The remote care group self-collected measurements for weight, blood pressure, and fetal heart rate by handheld Doppler device prior to each telemedicine visit and entered the information into the electronic medical record. The purpose of the self-collected data was patient engagement and satisfaction, as well as increased provider comfort with the change in prenatal care schedule, rather than medical necessity.

The primary outcome of overall patient satisfaction with prenatal care was ascertained by questionnaire after delivery. The sample size calculation of 200 patients was based on noninferiority testing, and analysis was by intent-to-treat. The details of the trial are pending publication.

As expected, the remote care group had significantly fewer in-clinic prenatal care visits compared with the usual care group (7.2 vs 11.3 visits); the total number of prenatal visits was not different between groups. Overall satisfaction with prenatal care was very high in both the remote care and the usual care group (100% vs 97%).

The virtual prenatal care model for low-risk pregnancies, consisting of a novel remote monitoring strategy and a reduced number of in-clinic visits, was not associated with lower patient satisfaction compared with traditional care.

New care strategy gives patients a choice. The success of this clinical trial has led to its programmatic adoption at the University of Utah, and low-risk women currently are offered a choice between participating in the Virtual Prenatal Care Program or receiving traditional prenatal care. The University of Utah is moving on from the one-size-fits-all approach to adopt new strategies that provide personalized evidence-based prenatal care at the lowest cost, while retaining high patient satisfaction. Formal cost-effectiveness analyses are underway.

WHAT IS YOUR APPROACH TO THE PERSISTENT OCCIPUT POSTERIOR MALPOSITION?

ROBERT L. BARBIERI, MD

(EDITORIAL; MARCH 2019)

A classic approach for managing fetal malposition

For those of us who trained and practiced obstetrics in the days of the 6% primary cesarean delivery (CD) rate, we never considered the management of the persistent occiput posterior (OP) position to be particularly difficult. I outline below a method that requires no unusual level of skill or dexterity.

1. The cervix must be fully dilated.
2. Dense regional anesthesia must be achieved.
3. The vertex must have reached +1 station.
4. The position must be clearly established, and this does not require anything other than the ability to palpate an ear, as it can be pointed only in one direction. If you feel ultrasonography is needed, be my guest.
5. Use an obstetric lubricant to reduce resistance and minimize lacerations.
6. While a trial of manual rotation is reasonable, it commonly will not succeed and requires that an operator’s hand be inserted rather than a slender and less traumatic device (forceps).
7. Next, palpate the sagittal suture to determine whether the position is straight OP versus left OP or right OP. This should not be difficult unless the poor woman has gone through 2 or 3 hours of unproductive pushing, thereby creating caput.
8. After proper forceps application is confirmed, gently apply upward pressure. This will make rotation easier.
9. Dr. Irving’s recommendations notwithstanding, the forceps handles are not carried in a wide sweep. One should use Kielland’s forceps, which do not have a pelvic curve and were invented for this precise indication. The forceps are simply rotated.
10. Try to avoid delivery as an OP, as this pulls a much larger diameter deflexed head through the pelvis and usually results in significant lacerations.
11. Episiotomy is not always required if rotation has succeeded.
12. Once descent to the outlet has been achieved, it is probably best to switch to a forceps with a pelvic curve to achieve easier extension.
13. This should complete the delivery, but as a general rule, if more than minimal resistance is met in any of the above steps, abandon the procedure and move to CD.
14. This process should result in at least a 70% success rate.

As is most likely understood by the current generation of obstetricians who appear to be satisfied with a 30% to 40% primary CD rate, the above reflects the views of a long-retired ObGyn (whose CD rate never exceeded 10%) and may be inappropriate for those who are not adequately trained in or comfortable with vaginal obstetrics.

HOW DO YOU FEEL ABOUT EXPECTANTLY MANAGING A WELL-DATED PREGNANCY PAST 41 WEEKS’ GESTATION?

ROBERT L. BARBIERI, MD

(EDITORIAL; FEBRUARY 2019)

Membrane stripping can be problematic

The recent discussion on stripping membranes to facilitate the initiation of labor and delivery was intriguing. This practice was reviewed extensively during my training in the 1960s and abandoned when the results were disappointing or contradictory. Although the practice has been revitalized recently, I am concerned that potential risks and the absence of a recommended protocol of safeguards may allow new problems to develop.

In a metropolitan community where I provide consultative services, the only patients I see for evaluation of pregnancies beyond 40 to 41 weeks come from providers who are non-physicians. Apparently, they are concerned that they may have to turn their patients over to physician providers for interventions that they are not capable of doing. My advice to them is simply that nothing good happens after 40 to 41 weeks.

Well-grown babies may continue to grow if they are healthy, and they may incur greater risks of dystotic labor and delivery resulting in injury or the need for physician-administered surgical assistance. If, on the other hand, growth markedly diminishes or ceases, fetal harm or neonatal complications may occur through asphyxia, meconium aspiration, or trauma. In either event, physician-based assistance is strongly encouraged, as long as due diligence in determining gestational age has been done.

Promoting membrane stripping without having a protocol for ascertainment of risk factors is worrisome to me. In my opinion, large population studies that fail to demonstrate increased risks of infection may fail to demonstrate that membrane stripping may induce a degree of perinatal infection comparable to that of prolonged labor with multiple internal examinations with or without ultimate cesarean birth. Prior to considering membrane stripping as a strategy, one should recognize certain important considerations, namely:

• Patients most in need of active intervention may have the least favorable cervical findings, and as a result they are potentially at risk for the greatest discomfort.
• The frequency of group B streptococcal colonization of the vagina at term should be recognized, and a culture should be obtained immediately prior to intervention. When a culture is a positive, membrane stripping should be avoided, or at least a sober consideration of its use and appropriate antibiotic coverage should occur.
• Consider performing transvaginal ultrasonography prior to membrane stripping to exclude the possibility of a placental edge close enough to be encountered and compromised, with resultant hemorrhage in an outpatient venue ill equipped to provide adequate emergency support.
• The comparative effectiveness of other direct cervical conditioning therapies, including use of a Foley catheter or regional prostaglandin medication, has been well explored and found effective. Also, if one takes seriously the need for any intervention, admission to the hospital for overnight cervical conditioning allows for surveillance and avoids the patient experience of being sent home cramping, bleeding, brooding infection, and questioning her trust in the provider.

Continue to: I am concerned that the promotion...

I am concerned that the promotion of this potentially rather brutish practice by highly reputable advisors can result in its growing utilization by providers some of whom may be least qualified to apply proper judgment and sensitivity to its selection. In the most primitive of circumstances, it may have utility. Personally, however, I feel that medically based strategies initiated and monitored by professionals capable of dealing with any untoward departures from the expected results must be considered in the best traditions of what we do. The appeal of simplicity must not encourage the adoption of interventions that lack the proper application of thought and plan and whose only appeal is that of simplicity.

Dr. Barbieri responds

I thank Dr. Priver for his excellent description of how to use forceps to resolve a persistent occiput posterior position. I also thank Dr. Perkins for his valuable comments and agree with him that in the United States among the options available for outpatient cervical ripening, misoprostol or a balloon are more commonly used than membrane stripping. Membrane stripping is an outpatient cervical ripening technique that is commonly used in the United Kingdom.

If, on the other hand, growth markedly diminishes or ceases, fetal harm or neonatal complications may occur through asphyxia, meconium aspiration, or trauma. In either event, physician-based assistance is strongly encouraged, as long as due diligence in determining gestational age has been done.

Promoting membrane stripping without having a protocol for ascertainment of risk factors is worrisome to me. In my opinion, large population studies that fail to demonstrate increased risks of infection may fail to demonstrate that membrane stripping may induce a degree of perinatal infection comparable to that of prolonged labor with multiple internal examinations with or without ultimate cesarean birth. Prior to considering membrane stripping as a strategy, one should recognize certain important considerations, namely:

• Patients most in need of active intervention may have the least favorable cervical findings, and as a result they are potentially at risk for the greatest discomfort.
• The frequency of group B streptococcal colonization of the vagina at term should be recognized, and a culture should be obtained immediately prior to intervention. When a culture is a positive, membrane stripping should be avoided, or at least a sober consideration of its use and appropriate antibiotic coverage should occur.
• Consider performing transvaginal ultrasonography prior to membrane stripping to exclude the possibility of a placental edge close enough to be encountered and compromised, with resultant hemorrhage in an outpatient venue ill equipped to provide adequate emergency support.
• The comparative effectiveness of other direct cervical conditioning therapies, including use of a Foley catheter or regional prostaglandin medication, has been well explored and found effective. Also, if one takes seriously the need for any intervention, admission to the hospital for overnight cervical conditioning allows for surveillance and avoids the patient experience of being sent home cramping, bleeding, brooding infection, and questioning her trust in the provider.

Continue to: I am concerned that the promotion...

I am concerned that the promotion of this potentially rather brutish practice by highly reputable advisors can result in its growing utilization by providers some of whom may be least qualified to apply proper judgment and sensitivity to its selection. In the most primitive of circumstances, it may have utility. Personally, however, I feel that medically based strategies initiated and monitored by professionals capable of dealing with any untoward departures from the expected results must be considered in the best traditions of what we do. The appeal of simplicity must not encourage the adoption of interventions that lack the proper application of thought and plan and whose only appeal is that of simplicity.

Dr. Barbieri responds

I thank Dr. Priver for his excellent description of how to use forceps to resolve a persistent occiput posterior position. I also thank Dr. Perkins for his valuable comments and agree with him that in the United States among the options available for outpatient cervical ripening, misoprostol or a balloon are more commonly used than membrane stripping. Membrane stripping is an outpatient cervical ripening technique that is commonly used in the United Kingdom.

Just when you thought cicada infestations couldn’t get worse – the cicadas are now zombies on an acid trip.

West Virginia University researchers recently discovered that a fungus called Massopora, which has compounds similar to those found in psychedelic mushrooms, can infect cicadas and cause seriously weird behavior.

How weird, you ask? Well, male cicadas try to mate with everything they encounter, even though the fungus has eaten away their limbs … and their genitals. Talk about a bad trip.

It gets worse. These zombie-like cicadas are flying around and exposing their healthy brethren to the fungus. So, now we have to worry about potentially billions of these buggers becoming rotting, flying, hypersexual machines.

Makes a person really want to stay inside for the whole summer, perhaps in a fortified bunker. Just in case.

Also, for the curious: One of the study’s authors concedes that if a person were “motivated enough,” they might be able to get high off the cicada fungus. Not interested in finding out exactly how many cicadas you’d have to crunch on before you start tasting colors?
 

Poster do-over

It’s time to get ready for a revolution – and just in time for 4th of July. No, we’re not redeclaring independence from Britain. It’s something much, much more radical, at least to the scientific community.

Get ready for … the redesign of the science poster.

Mike Morrison, a doctoral student in psychology, has proposed a new way to present information at meetings that breathes new life into the tired poster design. While fascinating insights could be held on a poster, the reality of meetings and conferences is that people often skim over the posters they see, barely registering the information.

Morrison is taking advantage of the ever-present smartphone to ramp up the classic science poster to a new level. He proposes a format where the key research finding is smack in the middle, in big, readable language. Accompanying this is a QR code you can scan, which would take you to a page with the full details of the study.

Morrison tweeted out his idea, and it spread quickly through the scientific community, gaining traction from younger scientists and students who love the idea.

We’re in the age of remakes now – in which classics are reinvented for a new audience. It’s time the science poster got a face-lift, too.
 

Running a marathon, one Veillonella at a time

What’s the difference between an elite athlete and a person who’s out of juice after running for 30 seconds?

Well, many things, we’re sure. A proper diet, rigorous training, not spending 12 hours a day sitting behind a computer screen. But just to add insult to injury, according to a study published in Nature Medicine, athletes even poop better than us normal people.

That may require a bit of explanation. A group of researchers from Harvard University, Boston, analyzed stool samples from elite marathon runners before and just after they participated in the 2015 Boston Marathon. They found that, following the race, the athletes had significantly higher amounts of Veillonella in their microbiota. This bacteria breaks down lactic acid, which is made during intense exercise and causes muscle fatigue and stress.

Naturally, the next step was to take that bacteria, feed it to mice, then get them running on a treadmill.

While not every mouse fed Veillonella saw increased performance, on average, mice that received the bacteria saw a 13% improvement over their non–Veillonella enhanced friends.

The researchers noted that this sort of probiotic treatment could be useful to patients with metabolic diseases, such as diabetes. Plus, there’s the obvious benefit to athletes. We look forward to hearing advertisements swearing by Veillonella-infused Wheaties, the true breakfast of champions.
 

Put a little boredom in your life

Is your job an endless, soul-sucking vortex of dreariness? Do you stare at the wall for hours at a time while you’re at work, wishing you had something better to do? Do you look forward to leaving early to go to the dentist? [Editor query: What does this have to do with health care? LOTME: You’ll see. We’re building dramatic tension.]

Did you answer yes to any of these questions? Way to go! You’ve taken the first step on the road to creativity. [Still waiting. We’re almost there.]

A recent study examined the effects of boredom by assigning people to either a really boring task – sorting a bowl of red and green beans by color for 30 minutes using only one hand – or a nonboring art project using paper, glue, and, of course, beans. [What’s with the beans? It’s not our fault they used beans.]

The next task was the same for both groups: Come up with some reasons for being late for work and think of ideas for a new product by a hypothetical company. The answers were graded on their uniqueness, and the bean-sorting group had more creative ideas than did the art-project group.

The point is, ladies and gentlemen, that boredom is good. Boredom is right. Boredom works. [A Gordon Gekko reference? Couldn’t you find something from this century? No.]

By now you’re probably wondering: “But how can I get one of those really boring jobs? After all, I’m a doctor. I heal the sick and care for the needy. My work is way too interesting to inspire true creativity.” Have you ever considered writing a medical humor column?

[Note to readers: We’ve pulled the staff away from their building blocks and crayons and given them a timeout. Hopefully things will be a little better by next week.]

MADRID – RSLV-132, a novel drug that eliminates circulating nucleic acids, improved the symptoms of mental fatigue in patients with primary Sjögren’s syndrome (pSS) in a phase 2, double-blind, randomized, placebo-controlled “proof-of-concept” study.

Vidyard Video

The mental component of fatigue on the Profile of Fatigue (PRO-F) scale improved by 1.53 points among the patients given RSLV-132, while there was a worsening of 0.06 points in the placebo group (P = .046). Scores range from 0 to 7 on the PRO-F.

There were also improvements in some patient-reported outcomes, namely the EULAR pSS Patient Reported Index (ESSPRI) and the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue (FACIT-F), and improvement of neuropsychological measures of cognitive function, but none were statistically significant. All of these outcomes, including fatigue, were secondary outcomes of the study.

“Fatigue is a major issue for patients with Sjögren’s syndrome,” Wan-Fai Ng, MBChB, PhD, said in an interview at the European Congress of Rheumatology. Indeed, fatigue can be disabling in the majority of individuals, he added.

Currently, the best way to manage fatigue is to first ask about it, said Dr. Ng, who is professor of rheumatology at the Institute of Cellular Medicine at Newcastle University, Newcastle-upon-Tyne, England. He then checks for any underlying problem that could be better managed – sleep problems or anemia, for example – and optimizes treatment for any underlying disease. “I think many people would at least feel satisfied that people take the symptoms seriously.”

Dr. Ng and his coauthors investigated the effects of RSLV-132, a first-in-class human RNase fused to the human Fc domain of human immunoglobulin (Ig) G1, in the RESOLVE 132-04 study. This novel drug been designed to increase serum RNase activity to digest RNA-associated immune complexes, Dr. Ng and associates observed in their abstract. As a consequence of this, they say, activation of toll-like receptors and the production of interferon (IFN) is affected, as is B-cell proliferation and the production of autoantibodies – all mechanisms that are “key to pSS pathogenesis.”

The IFN pathway has been implicated in fatigue, Dr. Ng observed when he presented the RESOLVE 132-04 study’s findings, which involved 30 patients with pSS who had been treated for 3 months. Inclusion criteria were pSS as defined by the American-European Consensus Group 2002 criteria, anti-Ro antibody positivity, and increased expression of three IFN-regulated genes: HERC5, EPSTI1, and CMPK2. Exclusion criteria were the use of hydroxychloroquine, prednisolone at daily doses above 10 mg, and the use of biologic disease-modifying antirheumatic drugs.

Patients were randomized in a 3:1 ratio to receive either 10 mg/kg of RSLV-132 (n = 20) or placebo (n = 8) at weeks 0, 1, 2, and then every fortnight until week 12. Dr. Ng noted that although 30 patients were randomized, two patients had dropped out in the placebo group before they could be “treated.”

The primary endpoint was the change in the blood cell gene expression or serum protein levels indicative of reduced inflammation. The results indicated reductions in noncoding RNA molecules in patients who received RSLV-132 versus placebo, “consistent with the mode of action of the molecule.” In addition, “the majority of inflammatory markers were reduced,” Dr. Ng said.

Another finding showed a nonsignificant trend for improvement of 0.8 units in the physical component in the RSLV-132 group, compared against 0.06 units with placebo (P = .142).

Patients who received RSLV-132 reduced the time needed to complete the Digital Symbol Substitution Test by 16.4 s, compared with an increase of 2.8 s for placebo (P = .024).

Similar trends were observed for ESSPRI and FACIT-F scores.

These are very early data and clearly a bigger study would be needed before any conclusions could be drawn, Dr. Ng said in an interview. What these data suggest is that “maybe there is some way that we could manage fatigue, and we just need to go and explore that.”

RSLV-132 has also been studied in patients with systemic lupus erythematosus (Lupus. 2017;26:825-34).

The trial was sponsored by Resolve Therapeutics. Dr. Ng was an investigator in the trial and disclosed other research collaborations with electroCore, GlaxoSmithKline, and AbbVie. He also disclosed acting as a consultant for Novartis, GlaxoSmithKline, AbbVie, MedImmune, Pfizer, and Bristol-Myers Squibb.

Cancer led to 492,000 deaths for Americans aged 16-84 years in 2015, and those deaths cost $94.4 billion in lost earnings that year, according to a study published in JAMA Oncology.

Cancer also took more than 8.7 million years of life from those individuals, with lung cancer being the most costly in terms of both lost earnings and years of life lost, said Farhad Islami, MD, PhD, and associates at the American Cancer Society, Atlanta.

“Person-years of life lost and lost earnings were high for many cancers associated with modifiable risk factors and effective screening and treatment, suggesting that a substantial proportion of the mortality burden is potentially avoidable,” they wrote, adding that “implementation of comprehensive cancer prevention interventions and equitable access to high-quality care across all states could reduce the burden of cancer and associated geographic and other differences in the country.”

In 2015, lung cancer took more than 2.2 million years of life and $21.3 billion in earnings from Americans aged 16-84 years. Colorectal cancer was next with 766,000 years of life lost and $9.4 billion in lost earnings, followed by female breast cancer with losses of 746,000 years of life and 6.2 billion in earnings, Dr. Islami and associated reported.

For all cancers, the cost in lost earnings per death was almost $192,000, with the highest costs coming from cancers of the brain and nervous system ($315,000) and cervix ($311,000). On that basis, lung cancer cost was lower than average at $159,000 per death, they noted.

At the state level, lost-earnings rates were lowest in Utah ($19.6 million per 100,000 persons) and highest in Kentucky ($35.3 million per 100,000). “If all states had Utah’s lost earnings rate in 2015, lost earnings in the U.S. would have been reduced by 29.3%, or $27.7 billion, and life years lost nationwide in 2015 would be reduced by 2.4 million,” Dr. Islami and his associates said in a written statement.

Data for the study were obtained from the National Center for Health Statistics (mortality) and the U.S. Census Bureau (earnings). The study was supported by the Intramural Research Department of the American Cancer Society, and all of the investigators are employees of the society.

EXPERT COMMENTARY

Cervical ripening is routine practice in women undergoing induction of labor who have an unfavorable cervical examination.¹ This is because generating contractions against a long thick cervix is more likely to lead to failed induction and cesarean delivery. Cervical ripening can be achieved using mechanical or pharmacologic methods.

Misoprostol (a prostaglandin E₁ [PGE₁] analog) is approved by the US Food and Drug Administration for the treatment of peptic ulcer disease, but it also is widely used off-label for cervical ripening, partly due to its low cost. Misoprostol’s optimal dosing regimen and route of administration are not known. The IMPROVE trial was designed to address this knowledge gap, specifically to compare the efficacy and safety of VM versus BM in women undergoing labor induction at term.

Details of the study

The IMPROVE trial was a prospective, randomized, noninferiority, triple-masked, placebo-controlled trial of 300 women with a singleton vertex fetus requiring cervical ripening for induction of labor at term.² Enrolled women were randomly assigned to VM or BM (same dosing regimen) and to a matching placebo administered via the opposite route.

Primary outcomes included time-to-vaginal-delivery from first dose, which was reduced in VM vs BM (20.1 vs 28.1 hours; P = .006), and urgent cesarean delivery for nonreassuring fetal testing, which was similarly reduced in VM (3.3% vs 9.5%; P = .33). These differences persisted after controlling for covariates. There was also a greater difference seen in multiparous versus nulliparous women.

Secondary outcomes also favored VM over BM, including more vaginal deliverieswithin 24 hours, fewer doses to achieve active labor, and a lower maximum dose of oxytocin.

Overall cesarean delivery rates were similar in the 2 groups (VM, 15.8%; BM, 22.3%; P = .15). There were no significant differences in other delivery characteristics or in maternal or fetal adverse events.

Continue to: Study strengths and limitations...

Study strengths and limitations

The IMPROVE trial had a triple-blinded study design with an intention-to-treat paradigm and good follow-up. There was also standardization of PGE₁ administration criteria, which was consistent with the American College of Obstetricians and Gynecologists standards of care. Results were similar to those of prior studies regarding rates of tachysystole, urgent cesarean delivery, and vaginal delivery.

The study has good generalizability as it included both elective and medically indicated inductions; however, patients with ruptured membranes were excluded. Although there was no difference in the overall cesarean delivery rates, the study was underpowered to look at this outcome. The authors included a patient satisfaction survey, but this is hard to interpret since study participants all received tablets orally and vaginally. The study did not address efficacy of VM versus BM administration at different doses or time intervals.

Clinical question: Can differences in hospital readmission rates be explained by patient characteristics not accounted for by Medicare?

Background: In its Pay for Performance program, Medicare ties payments to readmission rates but adjusts these rates only for limited patient characteristics. Hospitals serving higher-risk patients have received greater penalties. These programs may have the unintended consequence of penalizing hospitals that provide care to higher-risk patients.

Study design: Observational study.

Setting: Medicare admissions claims from 2013 through 2014 in 2,215 hospitals.

Synopsis: Using Medicare claims for admission and linked U.S. census data, the study assessed several clinical and social characteristics not currently used for risk adjustment. A sample of 1,169,014 index admissions among 1,003,664 unique beneficiaries was analyzed. The study compared rates with and without these additional adjustments.

Additional adjustments reduced overall variation in hospital readmission by 9.6%, changed rates upward or downward by 0.4%-0.7% for the 10% of hospitals most affected by the readjustments, and they would be expected to reduce penalties by 52%, 46%, and 41% for hospitals with the largest 1%, 5%, and 10% of penalty reductions, respectively.

Bottom line: Hospitals serving higher-risk patients may be penalized because of the patients they serve rather that the quality of care they provide.

Postpartum blood loss greater than 1,000 mL occurs in approximately 7% of cesarean delivery (CD) procedures with the administration of oxytocin alone or oxytocin plus misoprostol.¹ Rapid identification and control of hemorrhage is essential to avoid escalating coagulopathy and maternal instability. In cases of excess blood loss, clinicians request assistance from colleagues, endeavor to identify the cause of the bleeding, utilize additional uterotonics (methylergonovine, carboprost, misoprostol), perform uterine massage, warm the uterus, repair lacerations and replace blood products. If blood loss continues after these initial measures, obstetricians may consider uterine artery embolization (UAE) or hysterectomy. While UAE is a highly effective measure to control postpartum hemorrhage, it is not available at all obstetric hospitals. Even when available, there may be a significant time delay from the decision to consult an interventional radiologist to completion of the embolization procedure.

To avoid the permanent sterilization of a hysterectomy, or to obtain time for UAE or correction of coagulopathy, additional uterus-sparing surgical interventions should be considered. These include: 1) progressive uterine devascularization, 2) uterine compression sutures, and 3) intrauterine balloon tamponade. One caveat is that there is very little high-quality evidence from randomized trials to compare the efficacy or outcome of these uterine-sparing surgical interventions. Most of our evidence is based on limited case series and expert recommendations.

Uterine devascularization

Many techniques have been described for performing progressive uterine devascularization. Most experts recommend first performing an O’Leary suture, ligating both ascending uterine arteries and accompanying veins at a point approximately 2 cm closer to the cervix than the uterine incision (FIGURE 1). An absorbable suture is passed through the myometrium, being sure to remain medial to the ascending uterine vessels. Clear visualization of the vessels posteriorly is essential, usually necessitating exteriorization of the uterus. The needle is then driven through an avascular space in the broad ligament close to the uterine vessels, and the suture is tied down. Ureteral injury can be avoided by extending the bladder flap laterally to the level of the round ligament and mobilizing the vesicouterine peritoneum inferiorly, with the suture placed directly on endopelvic fascia. If necessary, the utero-ovarian ligament can be ligated in a second step, just below the uterine-tubal junction. The progressive devascularization intervention can be limited to the first or second steps if bleeding is well controlled.

In our experience, bilateral O’Leary sutures are highly effective at controlling ongoing uterine bleeding, particularly from the lower uterine segment. In the event that they are not successful, placement does not preclude later use of UAE.

Uterine compression sutures

Compression sutures are most often used in the setting of refractory uterine atony. They also may be helpful for controlling focal atony or bleeding from a placental implantation site. More than a dozen different types of uterine compression sutures have been reported in the literature; the B-Lynch, Hyman, and Pereira sutures are most commonly performed.²

Continue to: The B-Lynch suture³ is performed with...

1. Take bites on either side of the right edge of the hysterotomy incision (A and B). Place these bites approximately 3 cm from the edge of the hysterotomy incision.
2. Loop the suture around the fundus and reenter the uterus through the posterior uterine wall at point C, which is directly posterior to point B.
3. Exit the posterior wall of the uterus through point D.
4. Loop the suture over the uterine fundus.
5. Anchor the suture in the lower uterine segment by taking bites on either side of the left edge of the uterine hysterotomy incision (points E and F).
6. Pull the two ends of the suture tight while an assistant squeezes the uterus to aid compression.
7. Place a surgical knot to secure the suture.
8. Close the hysterotomy incision.

The B-Lynch suture was described with an open hysterotomy incision,³ which avoids closing off the lower uterine segment. We have successfully performed a modific tion on a closed uterus, taking care to not drive the lower uterine sutures through both the anterior and posterior walls.

The Hayman suture⁴ was proposed with two important modifications: The suture is placed through-and-through the lower uterine segment with a closed hysterotomy, and the suture can be fixed to the uterine fundus to avoid slippage. This vertical compression suture (FIGURE 3) is performed by placing two to four vertical #2 chromic sutures directly through the anterior to posterior uterine wall, tying the suture on the fundus using a 3-throw technique to minimize slippage of the first knot. In the original description, Hayman also described injecting carboprost into the uterine fundus to stimulate uterine contraction and regularly inspecting the vagina to evaluate the extent of continued bleeding.⁴

Intrauterine balloon tamponade

Many types of balloon tamponade devices have been developed, ranging from the humble condom tied to a Foley urinary catheter to the sophisticated Bakri^6,7 and Belfort-Dildy⁸ balloon tamponade devices. Intrauterine balloon tamponade is highly effective in controlling excess bleeding following vaginal delivery and less effective when used following a CD. In one study of 226 women with postpartum hemorrhage treated with a Bakri balloon the success rate was 89% and 66% following vaginal delivery and CD, respectively.⁹

Continue to: When using balloon tamponade during a CD...

When using balloon tamponade during a CD, some experts recommend partially closing the transverse hysterotomy incision by placing sutures to close edges of the hysterotomy, followed by insertion of the balloon into the uterus and the stem through the cervix into the vagina. Attachment of the stem to a collection bag should help to quickly assess the rate of blood loss. The balloon is inflated after the hysterotomy is closed. Following inflation of an intrauterine balloon, blood loss should decrease almost immediately.¹⁰ If excessive blood loss continues for more than 10 minutes, additional uterus-sparing interventions or hysterectomy may be required. Following successful balloon tamponade, the balloon may be deflated 12 to 24 hours postpartum when maternal stabilization and normal coagulation have been achieved. If bleeding resumes, the balloon may be reinflated and UAE should be considered.

Combined interventions: Uterine devascularization plus uterine compression sutures

There are no high-quality randomized trials comparing the devascularization plus compression sutures versus a single intervention alone, and case series and case reports on this topic are lacking. If uterine devascularization alone does not sufficiently control bleeding, adding a uterine compression stitch might resolve the hemorrhage. Both procedures require only suture material, which is immediately available in all operating rooms. Hence, this combination of interventions can be executed quickly.

Uterine sandwich: Intrauterine balloon tamponade plus uterine compression sutures

CD for placenta previa is associated with an increased risk of postpartum hemorrhage, with bleeding from the lower uterine segment greatly contributing to total blood loss. While O’Leary sutures can stem the flow of bleeding in this area, the use of both an intrauterine balloon tamponade plus uterine compression sutures—a so-called uterine sandwich—may result in maximal reduction in blood loss.^11,12

In one randomized trial, 106 women undergoing CD for a placenta previa were randomly assigned to uterine devascularization alone or double transverse compression suture at the lower uterine segment plus intrauterine Foley catheter balloon. Compared with women receiving devascularization alone, the combination of compression suture plus intrauterine balloon significantly reduced blood loss (1,350 mL vs 750 mL, respectively; P = .0001).¹³

Underutilization of uterine-sparing interventions

In a nationwide study of 50 consecutive Danish peripartum hysterectomy cases, an audit committee concluded that 24% of the hysterectomies could have been avoided, and an additional 30% of hysterectomies might have been avoided, if uterine-sparing surgical interventions had been utilized.¹⁴ In a recent survey of senior ObGyn residents in France, greater than 70% of respondents reported that they had not mastered uterine-sparing techniques of uterine devascularization and compression sutures, nor peripartum hysterectomy.¹⁵ Together, these studies suggest that uterine-sparing interventions are underutilized and that with more training and practice clinicians would become facile with these interventions.

The cornerstones of uterine-sparing surgical interventions are simplicity, safety, and efficacy. If a combination of pharmacologic and multiple uterine-sparing surgical interventions do not control the bleeding, the patient may need an emergency hysterectomy or, if stable, a UAE. While devascularization and compression sutures are described during CD, it is reasonable to use them after vaginal delivery if the next reasonable step would be a laparotomy. When you next face the clinical challenge of a postpartum hemorrhage, rapid recognition of excess blood loss, early identification of the cause, swift pharmacologic treatment, and timely escalation of surgical interventions will help you reduce the risk of hysterectomy and severe maternal morbidity.

Postpartum blood loss greater than 1,000 mL occurs in approximately 7% of cesarean delivery (CD) procedures with the administration of oxytocin alone or oxytocin plus misoprostol.¹ Rapid identification and control of hemorrhage is essential to avoid escalating coagulopathy and maternal instability.

5. Anchor the suture in the lower uterine segment by taking bites on either side of the left edge of the uterine hysterotomy incision (points E and F).
6. Pull the two ends of the suture tight while an assistant squeezes the uterus to aid compression.
7. Place a surgical knot to secure the suture.
8. Close the hysterotomy incision.

The B-Lynch suture was described with an open hysterotomy incision,³ which avoids closing off the lower uterine segment. We have successfully performed a modific tion on a closed uterus, taking care to not drive the lower uterine sutures through both the anterior and posterior walls.

The Hayman suture⁴ was proposed with two important modifications: The suture is placed through-and-through the lower uterine segment with a closed hysterotomy, and the suture can be fixed to the uterine fundus to avoid slippage. This vertical compression suture (FIGURE 3) is performed by placing two to four vertical #2 chromic sutures directly through the anterior to posterior uterine wall, tying the suture on the fundus using a 3-throw technique to minimize slippage of the first knot. In the original description, Hayman also described injecting carboprost into the uterine fundus to stimulate uterine contraction and regularly inspecting the vagina to evaluate the extent of continued bleeding.⁴

Intrauterine balloon tamponade

Many types of balloon tamponade devices have been developed, ranging from the humble condom tied to a Foley urinary catheter to the sophisticated Bakri^6,7 and Belfort-Dildy⁸ balloon tamponade devices. Intrauterine balloon tamponade is highly effective in controlling excess bleeding following vaginal delivery and less effective when used following a CD. In one study of 226 women with postpartum hemorrhage treated with a Bakri balloon the success rate was 89% and 66% following vaginal delivery and CD, respectively.⁹

When using balloon tamponade during a CD, some experts recommend partially closing the transverse hysterotomy incision by placing sutures to close edges of the hysterotomy, followed by insertion of the balloon into the uterus and the stem through the cervix into the vagina. Attachment of the stem to a collection bag should help to quickly assess the rate of blood loss. The balloon is inflated after the hysterotomy is closed. Following inflation of an intrauterine balloon, blood loss should decrease almost immediately.¹⁰ If excessive blood loss continues for more than 10 minutes, additional uterus-sparing interventions or hysterectomy may be required. Following successful balloon tamponade, the balloon may be deflated 12 to 24 hours postpartum when maternal stabilization and normal coagulation have been achieved. If bleeding resumes, the balloon may be reinflated and UAE should be considered.

Combined interventions: Uterine devascularization plus uterine compression sutures

There are no high-quality randomized trials comparing the devascularization plus compression sutures versus a single intervention alone, and case series and case reports on this topic are lacking. If uterine devascularization alone does not sufficiently control bleeding, adding a uterine compression stitch might resolve the hemorrhage. Both procedures require only suture material, which is immediately available in all operating rooms. Hence, this combination of interventions can be executed quickly.

Uterine sandwich: Intrauterine balloon tamponade plus uterine compression sutures

CD for placenta previa is associated with an increased risk of postpartum hemorrhage, with bleeding from the lower uterine segment greatly contributing to total blood loss. While O’Leary sutures can stem the flow of bleeding in this area, the use of both an intrauterine balloon tamponade plus uterine compression sutures—a so-called uterine sandwich—may result in maximal reduction in blood loss.^11,12

In one randomized trial, 106 women undergoing CD for a placenta previa were randomly assigned to uterine devascularization alone or double transverse compression suture at the lower uterine segment plus intrauterine Foley catheter balloon. Compared with women receiving devascularization alone, the combination of compression suture plus intrauterine balloon significantly reduced blood loss (1,350 mL vs 750 mL, respectively; P = .0001).¹³

Underutilization of uterine-sparing interventions

In a nationwide study of 50 consecutive Danish peripartum hysterectomy cases, an audit committee concluded that 24% of the hysterectomies could have been avoided, and an additional 30% of hysterectomies might have been avoided, if uterine-sparing surgical interventions had been utilized.¹⁴ In a recent survey of senior ObGyn residents in France, greater than 70% of respondents reported that they had not mastered uterine-sparing techniques of uterine devascularization and compression sutures, nor peripartum hysterectomy.¹⁵ Together, these studies suggest that uterine-sparing interventions are underutilized and that with more training and practice clinicians would become facile with these interventions.

The cornerstones of uterine-sparing surgical interventions are simplicity, safety, and efficacy. If a combination of pharmacologic and multiple uterine-sparing surgical interventions do not control the bleeding, the patient may need an emergency hysterectomy or, if stable, a UAE. While devascularization and compression sutures are described during CD, it is reasonable to use them after vaginal delivery if the next reasonable step would be a laparotomy. When you next face the clinical challenge of a postpartum hemorrhage, rapid recognition of excess blood loss, early identification of the cause, swift pharmacologic treatment, and timely escalation of surgical interventions will help you reduce the risk of hysterectomy and severe maternal morbidity.

Postpartum blood loss greater than 1,000 mL occurs in approximately 7% of cesarean delivery (CD) procedures with the administration of oxytocin alone or oxytocin plus misoprostol.¹ Rapid identification and control of hemorrhage is essential to avoid escalating coagulopathy and maternal instability. In cases of excess blood loss, clinicians request assistance from colleagues, endeavor to identify the cause of the bleeding, utilize additional uterotonics (methylergonovine, carboprost, misoprostol), perform uterine massage, warm the uterus, repair lacerations and replace blood products. If blood loss continues after these initial measures, obstetricians may consider uterine artery embolization (UAE) or hysterectomy. While UAE is a highly effective measure to control postpartum hemorrhage, it is not available at all obstetric hospitals. Even when available, there may be a significant time delay from the decision to consult an interventional radiologist to completion of the embolization procedure.

To avoid the permanent sterilization of a hysterectomy, or to obtain time for UAE or correction of coagulopathy, additional uterus-sparing surgical interventions should be considered. These include: 1) progressive uterine devascularization, 2) uterine compression sutures, and 3) intrauterine balloon tamponade. One caveat is that there is very little high-quality evidence from randomized trials to compare the efficacy or outcome of these uterine-sparing surgical interventions. Most of our evidence is based on limited case series and expert recommendations.

Uterine devascularization

Many techniques have been described for performing progressive uterine devascularization. Most experts recommend first performing an O’Leary suture, ligating both ascending uterine arteries and accompanying veins at a point approximately 2 cm closer to the cervix than the uterine incision (FIGURE 1). An absorbable suture is passed through the myometrium, being sure to remain medial to the ascending uterine vessels. Clear visualization of the vessels posteriorly is essential, usually necessitating exteriorization of the uterus. The needle is then driven through an avascular space in the broad ligament close to the uterine vessels, and the suture is tied down. Ureteral injury can be avoided by extending the bladder flap laterally to the level of the round ligament and mobilizing the vesicouterine peritoneum inferiorly, with the suture placed directly on endopelvic fascia. If necessary, the utero-ovarian ligament can be ligated in a second step, just below the uterine-tubal junction. The progressive devascularization intervention can be limited to the first or second steps if bleeding is well controlled.

In our experience, bilateral O’Leary sutures are highly effective at controlling ongoing uterine bleeding, particularly from the lower uterine segment. In the event that they are not successful, placement does not preclude later use of UAE.

Uterine compression sutures

Compression sutures are most often used in the setting of refractory uterine atony. They also may be helpful for controlling focal atony or bleeding from a placental implantation site. More than a dozen different types of uterine compression sutures have been reported in the literature; the B-Lynch, Hyman, and Pereira sutures are most commonly performed.²
