BABE Series: Cesarean Section Role Play Helps Prepare Families

April 30th, 2015 by avatar

apron and babyToday, in our monthly series “Brilliant Activities for Birth Educators” (BABE), I would like to share one of the activities that I do in my Lamaze class to help families feel prepared for a cesarean section. Most families in my classes are planning a vaginal birth, but it never hurts to be prepared should plans change.  One in three pregnant people will birth by cesarean in the USA.  April is Cesarean Awareness Month and that is why I am sharing this activity at this time.

Objectives

My objectives for this specific activity are threefold – 1) to share how the procedure is done 2) to offer different options that might be available for the family to request (skin to skin in the OR, delayed newborn procedures, etc., and 3) brainstorm the role of the support person during a cesarean and what kind of support the pregnant person will find comforting and helpful.

This role play is done in the fifth week of a seven week series. We have just covered variations in labor (induction, augmentation, EFM, AROM, pain medications, assisted second stage and more). They have heard about the hard and soft reasons for a cesarean and now I hope that they will understand the procedure and the choices and options they might have at the time.

Supplies for the activity and the setup

  • Cesarean apron
  • surgical masks
  • drape
  • soft baby
  • hair nets
  • scrubs
  • surgical clothing
  • laminated labels for each role
  • optional – IV bag, BP cuff, EKG leads, etc
up close cesarean apron

Up close of four zippers on cesarean apron

My main prop in this activity is a “cesarean apron” handmade by Kris Avery, a fellow LCCE here in Washington State. The apron has breasts, a belly button and some pubic hair painted on it, but what makes it special is a series of zippers that correspond to the different layers of a person’s body that will be cut during the cesarean procedure. Each zipper is sewn into a different layer and opens to reveal the layer underneath. The skin is represented by the apron, and then there is a layer of fat (yellow felt) that zips open, revealing the uterus (red felt). There are no muscles to “open” because as we know, the abdominal muscles are retracted and not cut. Finally, underneath the uterus, is the amniotic sac, represented by a thin white nylon material.

I ask a partner to come with me out of sight of the class and place the cesarean apron on them. All the zippers are closed. I place a soft baby doll (I use the baby from IKEA) underneath the apron with the head positioned right near the inner zipper.  Sometimes I place the baby in the breech position and plan on having the bum be removed first. When the partner is ready, we walk together back into the classroom and I ask them to lay on a table, where I have placed a pillow.

How I conduct the role play

I invite two class members to come up and hold a drape at chest level, just like it might be positioned in the OR.  I hand out laminated cards to all the other class members. Each card has the role of someone who might be in the OR during a cesarean section – surgeon, baby nurse, anesthesiologist, surgical tech, respiratory therapist, and so on.   I ask the pregnant person who is partnered with my “cesarean person” to play the role of “partner.”  I invite the partner to get into the white “moon suit” that is normally provided to family members during a cesarean.  I hand out hair nets, scrubs, face masks, surgical gowns, to all those who will be in the OR and everyone suits up.  I position all the “actors” in the appropriate spot.  Some go by a pretend “baby warmer” and others stand around the birthing person while others go where they might be in the real operating room. I talk about how hard it is to tell who is in the room and what their role is, when everyone is wearing scrubs/gowns/hats/masks and suggest that they ask people to introduce themselves.  I discuss strategies that the birthing person can use if they are temporarily separated from their support person.  I bring the support person over and seat them at the head of the OR table near the “anesthesiologist” and discuss how they cannot see over the drape for both the patient and the partner. The partner can stand up at the time of birth if they wish, or together they could ask for the drape to be dropped at that moment.  I ask the pregnant person how they are feeling as the surgery is about to begin.FullSizeRender

I walk everyone through the procedure step by step and describe what is happening.  I share what noises they might hear, and what sensations the pregnant person might “feel.”  (Tugging, pressure, pulling, but no pain.)  I try and give a sense of how long it takes for each part of the operation, (prep, incision to baby, closure)  I ask the surgeons to begin to open the zippers, and talk about each layer that they come to.  Finally the surgeons are through the amniotic sac and they reach in and remove the baby’s head through the opening. It is a somewhat tight fit and we discuss how that might benefit the baby.

The baby is delivered, shown to the parents and taken over to the “warmer” where the baby team is waiting.  I encourage partner to go over and see the baby, initiate talking to the baby and start sharing information with the birthing person – what the baby looks like, how s/he is doing, and so on.

cesarean apronWe go on to discuss how the partner can facilitate having the baby brought over to the birthing person ASAP, skin-to-skin, what might need to happen if baby is moved to the special care nursery, and more.  Throughout all of this, the class participants are role-playing through all of the likely activities and people are stepping up to help the family to have a positive experience, within the scope of their assigned role.  The surgeons close (zip up) the different layers and close the outer zipper on the skin.

I am leaving out much of the detail, as I am confident that you can fill in the activities that happen when a person is prepped, taken to the OR, has the cesarean surgery and is then taken to recover.  My hope is to have parents aware of some of the major points of the overall procedure.

Processing the activity

The class members take off the “costumes” and return to their seats.  I feel it is very important to debrief this activity.  It can be overwhelming to some. We debrief further, discussing any observations they had, how they felt as our role play was happening. I ask what are the values that are important to them and their family, if a cesarean should be needed.  A discussion also takes place about what a cesarean recovery plan might look like and how the family’s needs might change if they do not have a vaginal birth.

How is this activity received?

IMG_0116During the activity, class members are usually very engaged and creative in answering questions, acting out their “roles” and brainstorming solutions to the situations I present.  The real magic happens when we debrief.  I can see the wheels turning as families articulate what they will want and need should they have a cesarean birth.  They learn that they have a voice and can share what is important with their medical team.

Time and time again, I receive emails and and notes from class members who ended up having a cesarean. They share how “accurate” our role play was and how it helped them to understand the steps involved with their cesarean.  They were able to speak up in regards to their preferences and felt like their class preparation helped to reduce their stress and anxiety.

Summary

This activity takes time and I often wonder if I should replace it with something much shorter that covers the same topic.  But, I continue to do this role play activity because I see how it really helps families to understand how to play an active role in the birth of their baby, even if it is by cesarean section.

Other resources that I share with the class are the following links:

How might you make a “cesarean apron” that you could use for this activity?  Do you have ideas on how you could modify this activity for your classes?  What other things do you do to help your families to be prepared for a cesarean birth?  I would love to learn how you cover this important topic.  Please share your ideas in the comments section below.

The Healthy Birth: Dyad or Triad? Exploring Birth and the Microbiome

April 28th, 2015 by avatar

By Anne Estes, PhD, Illustrated by Cara Gibson, PhD

There has been much discussion and burgeoning research on how the mode of birth affects the microbiome of the infant (and later on the adult).  It is becoming clear that how babies are born impacts the type of bacteria that take up residence in and on our bodies. Today, I would like to welcome researcher and writer Anne Estes, PhD, and researcher and illustrator Cara Gibson, PhD to Science & Sensibility.  Anne shares information on the research into a newborn’s (and later on the adult) microbiome and how it can be affected by the location of birth, the type of birth and the interventions that occur during birth.  Learn more about what this new field of research is telling us about the importance of the microbiome. Stay tuned for a future interview by Anne, with some of the research scientists attempting to supplement the microbiome of infants delivered by planned Cesareans. – Sharon Muza, Science & Sensibility Community Manager

Birth plans often change. Neither my husband nor I anticipated the series of interventions with my first daughter’s birth. In the end, though we had the most important outcome – a healthy mom and baby dyad. How did these interventions influence the health of the third, silent, and invisible member of my daughter’s birth that I hadn’t included in her birth plan – her microbiome?

The helpful and harmful bacteria, viruses, and fungi that live in and on every environment, both living and non-living, are the microbiome of that environment. The bacterial component of the microbiome is best understood to date and will be this post’s focus. An organism’s microbiome influences the development and health of those animals and plants, whereas the microbiome of soil and buildings influence organisms that reside in those non-living environments. Our helpful microbes provide services that range from vitamin synthesis and food degradation to preventing attacks by pathogens. However, in the last few centuries of human-microbe interactions, changes in our birth and medical practices and living conditions may have altered the acquisition of our microbial communities. Our altered microbiomes, especially in the industrialized world, may help explain the increase in allergies, asthma, diabetes, gastrointestinal diseases, and mental disorders, such as depression, anxiety, and autism.

Humans as ecosystems for microbes

To a bacterium, you are a planet made up of several different ecosystems. From the dry, UV-intense “desert” of your skin to the warm, wet, nutrient-rich “lake” of your mouth, specific bacteria live in different regions on a person, just as specific vertebrate animals live in different ecosystems on the Earth (Figure 1, left and center). As ecosystems of the human environment change during development, pregnancy, or with changing diets, which bacterial species remain or how these microbial species function may shift is slowly becoming understood. How do we first acquire these microbes? Previous posts here and other blogs have done excellent reviews of the human microbiome and birth, so my post will serve to provide updates and pose new questions for consideration.

Fig1_MapLadies6

The source of the infant microbiome

The infant microbiome is acquired during birth [1, 2], from first foods [3-5], and the environment [6], and may also be partially colonized in utero [7]. The microbiome of infants born vaginally most closely represents the microbiome of the mother’s vagina and feces [1], and is rich in beneficial bacteria such as Bifidobacterium longum subsp. infantis and Bacteroidetes [8, 9] (Figure 2, left). In contrast, the microbiome of infants born via planned Cesarean is more similar to that of the mother’s skin and hospital environment [1]. The microbiomes of planned Cesarean-born infants are more likely to have hospital-acquired pathogens such as Clostridium difficile, methicillin-resistant Staphylococcus aureus (MRSA), and pathogenic Es. coli [1] and lack beneficial Bacteroidetes and Bi. longum subsp. infantis [10] (Figure 2, right). However, when beneficial Bifidobacterium were occasionally present in Cesarean-born infants, pathogenic Es. coli and C. difficile were not found [11] suggesting that one benefit of Bifidobacterium, especially Bi. longum subsp. infantis, may be outcompeting these potential pathogens.

Influence of birth mode on microbiome transmission

Repeatedly, studies in different countries, ethnic groups, ages, and health status have suggested that planned Cesarean-born infants are more likely to have more health issues and a different microbiome, as compared to vaginally born infants [2, 10, 12-14]. These differences in community composition can even be seen in adulthood [15]. A new Canadian study finds that the microbiome of infants born via unplanned Cesarean had increased bacterial richness and diversity, more similar to that of vaginally born infants than planned Cesarean [10]. Unfortunately, this was only a small study where fewer than ten mother-infant pairs were examined. Several variables such as length of time in labor or how far labor progressed, antibiotic use, natural vs. artificial rupture of membranes, and/or other interventions that may influence the microbiome were also not examined [10]. However, it does suggest that the process of labor, perhaps the hormonal or other physiological changes, may influence the microbiome. Additionally, some maternal bacteria may be transmitted when membranes rupture during labor [10]. Are bacteria “eavesdropping” on the chemical changes in the human to prepare themselves for transmission to the baby? Do these maternal hormone changes lead to increased vaginal or gut epithelial sloughing to transmit more or specific bacteria? Certainly, studies with larger sample sizes that can help control for these variables along with experimental studies on model animals are warranted.

Influence of birth place on microbiome transmission

Infants also acquire a proportion of their microbiome from their physical, inanimate surroundings. What proportion of the microbiome and which bacteria are acquired most likely depends on how many and what kinds of bacteria are acquired in utero, through birth method, and first foods. Since Cesarean delivered infants seem to be exposed to a lower density of maternal bacteria than vaginally delivered babies, the former may be more likely to acquire bacteria from their environment. However, this hypothesis has not been examined.

Fig2_MicrobirthVagvC5

 

Just as living organisms are a microbial environment, so are non-living structures such as buildings. Scientists at several universities working together on The Microbiology of the Built Environment Project funded by the Sloan Foundation are comparing the microbes of homes and hospitals. They have found that buildings are quickly colonized by the microbes of the people living in them [16]. Such rapid colonization specific to the individual being housed is even seen in infants in the neonatal intensive care unit (NICU) [17, 18] (Figure 3).

Fig3_Locations4

One group is surveying the microbiome of a hospital over time, as it is being built and then occupied. Hospital-acquired infections are an increasing concern for all patients, especially newborns. Infants born by Cesarean have an increased rate of MRSA, C. difficile, and other opportunistic pathogens [1]. However, different hospitals and even wards within a hospital might be expected to have disparate levels of pathogens depending on how prevalent the disease is within the hospital patients and staff. Whether freestanding birth centers, operating rooms dedicated to labor-and-delivery only, and mixed-use operating rooms have dissimilar microbiomes has yet to be investigated. Infants born in private homes would be exposed to the same microbiomes of members of the household.

 

Influence of first foods on microbiome transmission

Fig4_MicrobirthBreastvBottle5First foods are another influence on the infant microbiome. Breastfed infants have two “moms:” their human mother and their Milk-Oriented Microbiota (MOM) (Figure 4, left). The MOM are beneficial, protective bacteria in the infant’s gut that thrive when fed the sugars in breast milk [19]. Although human milk oligosaccharides (HMOs) are the third most abundant component of breast milk, the infant cannot digest these sugars. Instead, HMOs are a natural prebiotic or “bacterial food”. Various HMO sugar types and concentrations influence bacterial diversity, keeping strains of Bifidobacterium longum subsp infantis in highest abundance in the first few months of life and preventing pathogens from binding to the gut [20]. HMOs vary between pre-term and full term birth, vaginal deliveries and planned Cesarean births (reviewed in [20]), and even between mothers with different types of “secretor” genes [21]. Does this HMO variability serve to maintain and enhance some of the differences in bacterial communities between individuals? In addition to the MOM, a diversity and abundance of bacteria are found in breast milk. The average breastfed baby is exposed to between 1 and 10 million bacteria daily from their mother’s milk [5]! The breast milk microbiome is a unique assemblage of bacteria, distinct from human skin, gut, oral, vaginal, and other specific body site microbiomes [4]. Like other components of breast milk, the bacterial community changes dramatically between colostrum and mature milk with colostrum being the most diverse with over 1,000 different bacterial types [4]. Although only ten women were followed, it is intriguing that the breast milk microbiome of women delivering via planned Cesarean at birth, one month, and six months post-birth, was more similar to their gut microbiome than the breast milk of mothers who delivered vaginally [4]. Milk of moms undergoing unplanned Cesarean and vaginally delivering mothers were most similar [4]. How the presence of different microbes influences the developing human infant immune system has yet to be determined. Additionally, does the breast milk bacteria colonize the infant gut or are they digested? Could breast milk bacteria change how the MOM infant gut microbiome works as they pass through the gut, as one probiotic does in elderly patients [22]?

Formula-fed babies have a more diverse and rich microbiome than breast-fed babies, with lower numbers of Bifidobacterium and higher abundances of Peptostreptococcaceae, which includes C. difficile [10, 23] (Figure 4, right). Gut bacterial diversity is essential in increasing the ability of adults to digest a wide variety of foods. However, bacterial diversity may be detrimental in the infant stage when the immune system is developing and learning to distinguish between microbes that are friends and those that are foes. Breast milk sugars may mediate the relative abundances of different bacterial species [24]. Through studies like the Milk Bioactives Program at University of California at Davis, more is learned about the interaction between breast milk sugars and specific bacteria that can lead to better probiotic and prebiotic formulas and improve infant health.

Influence of in utero environment on microbiome transmission

Many other factors surrounding birth may influence the infant microbiome. High levels of reported maternal stress and high cortisol concentrations during pregnancy, correlated with lower relative abundances of beneficial Lactobacillus and Bifidobacterium sp. and higher abundances of Proteobacteria, such as Enterobacter and Escherichia. Infants of these highly stressed mothers had increased reports of gastrointestinal symptoms and allergic reactions, though these issues were reported by caregivers, not physicians, which may confound the findings [25]. A separate study found infants whose gestation lengths were less than 38 weeks had microbiome communities that were low in Bifidobacterium and took 3 to 6 months to reach a normal Bifidiobacterium-rich community as compared to infants born at 40 or more weeks [9]. Finally, the use of antibiotics during pregnancy [12] may also lead to infant health issues.

Do birth interventions change the microbiome?

The potential “eavesdropping” of bacteria on human hormones during pregnancy and labor led me to wonder how the use of synthetic hormones such as Pitocin, especially during stalled labor, might influence the microbiome and overall infant health. There are so many variables to the birth process that many of these questions could only be answered with extremely detailed data of tens of thousands of mother-infant-microbiome triads over time. The influence of interventions such as epidurals, frequency of cervical checks, episiotomies, vaginal preparation with betadine, enemas, and other procedures used during labor and delivery also have not been extensively examined. In general, any procedure that “sterilizes” or cleans the vaginal and rectal area would most likely decrease the transmission of the mother’s microbial community. Whether cervical checks introduce skin or environmental microbes to the infant should also be considered. Finally, what effect does postponing baby’s first bath until 24 or 48 hours after birth have on microbial colonization? What role does the vernix have in facilitating the colonization of the infant’s microbiome?

From lab bench to birth room

Antibiotics, Cesarean delivery, and other interventions are valuable and life-saving for many women and infants; however, as they have become more commonly used we have seen an increase in many long-term diseases and disorders. Recent microbiome research suggests that we should consider birth as delivering and nurturing a healthy triad – mom, infant, and microbiome. Currently, studies are being conducted to swab Cesarean delivered infants with vaginal secretions immediately after birth. Should fecal microbiome members also be considered? If hormone surges are important for the microbiome transmission during labor and in breast milk, as the unplanned Cesarean data suggest, how could the natural hormone surges of labor be mimicked for planned Cesarean? When antibiotics are needed for mother or infant, how best can we quickly repopulate the disturbance to the native microbiome?

Humans, and all organisms, are planets with diverse ecosystems. In sequencing of the human genome, we learned that diseases rarely correlated to specific human genes. Most likely instead of focusing on only the human or only the microbes, we should be examining the intersection between human genomics and microbiome structure and function to best understand health and disease of human-microbe ecosystems. Both human genomics and microbiome work are in their infancy (pun intended). Researchers examine correlations to develop testable hypotheses that can be examined in non-human animal models. Yet many of the microbes of interest are currently unable to be cultivated for direct testing or probiotic use. At this time, directly translating research findings to the delivery room is difficult, but I hope that this post will stimulate thought and conversations about the silent, invisible, yet important third member of human birth and life.

Because… A Poem Honoring Cesarean Awareness Month

April 9th, 2015 by avatar

CAM 2015 GBWCGiving Birth with Confidence is the sister blog to Science & Sensibility, Lamaze International and is geared for parents and new families.  Cara Terreri, ( you may remember Cara, we followed her journey to becoming an LCCE) has been the Community Manager there since the blog was first established in 2008.  I always point the families in my classes to Giving Birth with Confidence because I know that they will find evidence based information along with great inspiration to push for a safe and healthy birth.

Cara recently wrote and published a poem on Giving Birth With Confidence to commemorate Cesarean Awareness Month (April), and it really spoke to me.  Since April is also National Poetry Month, I wanted to share her poem with you, in hopes that you might pass on and share with the families you work with.  Because 1 in 3 is too many.

Because…

1 in 3 is too many

Recovery is hard

My birth was still a birth

I want to have a VBAC

My scar still hurts

I was separated from my baby

My doula supported me in the OR

I didn’t have a choice

I got to experience skin to skin with my baby right away

I made the choice this time

I wish I would have known

I feel cheated

My doctor never told me this could happen

It’s going to be OK

My sister said this was easier anyway

My midwife made the right decision to transfer to the hospital

Friends told me at least I had a healthy baby

I have postpartum depression

It was the best decision for my birth

My husband has scars too

I’m embarrassed

My doula wasn’t allowed back into the OR

I failed the one thing I’m supposed to be able to do as a woman

My mom had one too; I guess it was meant to happen

I know my doctor helped me make the best decision

I want more for my daughter

I am a source of courage and support for others who have gone before me and those who will go after me

I did the best that I could with the knowledge I had at the time

I’m doing better now

My baby is beautiful

My body is strong

I am resilient

My birth matters

Too Bad We Can’t Just “Ban” Accreta – The Downstream Consequences of VBAC Bans

April is Cesarean Awareness Month (CAM), and throughout the month, Science & Sensibility will be covering issues that are directly related to the number of cesareans (1,284,339 in 2013) performed every year in the United States.  To start our CAM series off, Jen Kamel, founder of VBACFacts.com, shares important information about placenta accreta.  Tomorrow, April 3rd, is the Hope for Accreta Awareness National Blood Drive, as part of the 30 Day Hope for Accreta Challenge sponsored by the Hope for Accreta nonprofit that provides consumer information and offers support to families affected by placenta accreta. – Sharon Muza, Community Manager, Science & Sensibility

cam lamaze 2015Even though the American College of Obstetricians and Gynecologists (ACOG) and the National Institutes of Health (NIH) have described vaginal birth after cesarean (VBAC) as a safe, reasonable, and appropriate option for most women, VBAC bans (hospital or practice wide mandates that requires repeat cesareans for all women with a prior cesarean) remain in force in almost half of American hospitals. It’s true that scheduled repeat cesareans almost always successfully circumvent the most publicized risk of VBAC (uterine rupture) by virtually eliminating its incidence and for this reason, many people celebrate and credit the repeat cesarean section for resulting in a good outcome for mother and baby. But what most people do not consider is that VBAC bans translate into mandatory repeat cesareans, and those surgeries expose women and babies to a condition far more life-threatening and difficult to treat than uterine rupture: placenta accreta.

Placenta accreta occurs when a placenta abnormally attaches to (accreta), in (increta), or through (percreta) the uterine wall. No one knows exactly why some women develop accreta other than there is some abnormality in the area where the fertilized egg implants (Heller, 2013). Anyone who has had a prior surgery on her uterus is at a substantially increased risk of accreta and, as it happens, cesarean section is the most common surgery in the United States (Guise, 2010). In fact, the rate of accreta has grown along with the rate of cesarean surgery: from 1 in 4,027 pregnancies in the 1970s, to 1 in 2,510 pregnancies in the 1980s, to 1 in 533 from 1982-2002 (American College of Obstetricians and Gynecologists [ACOG], 2012). That rate escalates to 1 in 323 among women with a prior uterine surgery and the risk rises at a statistically significant rate with each additional cesarean section (Silver, Landon, Rouse, & Leveno, 2006).

Up to seven percent of women with accreta will die from it (ACOG, 2012). After the baby is born, the placenta does not detach normally, causing bleeding, which can’t be stopped before the doctors are able to either surgically remove the placenta or perform an emergency cesarean hysterectomy. Babies die from accreta due to the very high rate of preterm delivery associated with accreta. In fact, 43% of accreta babies weigh less than 5.5 lbs (2,500 gm.) upon delivery (Eshkoli, Weintraub, Sergienko, & Sheiner, 2013). Accreta is not a routine complication. Accreta is serious.

As Silver (2006) points out, the risk of accreta after two cesareans (0.57%) is greater than the risk of uterine rupture after one prior low transverse cesarean during a non-induced/augmented planned VBAC (0.4%) (Landon, Hauth, & Leveno, 2004). In other words, women are literally exchanging the risk of uterine rupture in a current pregnancy for the more serious risk of accreta in future pregnancies. This poses a striking public health issue when you combine what the CDC (2012) has reported for numbers of unintended pregnancies–49%–and the lack of access to vaginal birth after cesarean: over half a million repeat cesareans every year, resulting in higher rates of accreta.

Yet due to the nonmedical factors that inhibit access to VBAC and influence how the risks and benefits of post-cesarean birth options are communicated to the public, women are rarely informed of these risks in a transparent and straightforward way. Additionally, it can be very difficult for the woman to obtain social support when confusion and fear about giving birth after cesarean remains the norm.

Given all this, providers are ethically obligated to inform patients of the future implications of their current mode of delivery. However, it can be especially difficult for providers working within the political climate of a hospital where VBAC is banned to frankly inform their patients of this reality. How can providers clearly explain to women the risks and benefits of their options, with VBAC as a viable option, when they do not offer that option at the facility? Such a situation could even result in professional ramifications for the provider, like revocation of hospital privileges. Additionally, some providers do not offer VBAC, “not because of an explicit hospital policy against it, but because [they] were unwilling to stay in the hospital with a woman attempting [a planned VBAC]” (Barger, Dunn, Bearman, DeLain, & Gates, 2013).

It is for this reason that some argue that VBAC bans create a conflict of interest among providers (ACOG, 2011; Charles, 2012). On one hand, they are bound by ethical obligations to the patient’s well-being, respect for patient autonomy, and support of an informed decision-making process. But these obligations are threatened by financial and professional ties to the hospital.

ACOG stresses throughout their guidelines and committee opinions that informed consent and patient autonomy are paramount (ACOG, 2011). They share how obstetrics should be moving from a paternalistic system to a more collaborative model (ACOG, 2013). They acknowledge that women should be allowed to accept increased levels of risk (ACOG, 2010). They assert how there is no “right” or “wrong” answer, only what is right or wrong for a specific woman (ACOG, 2010). And they are clear that restrictive VBAC policies cannot be used to force women to have a repeat cesarean or to deny a woman care during active labor (ACOG, 2010).

Yet, with 48% of women interested in the option of VBAC, 46% of them cannot find a provider or facility to attend their VBAC (Declercq, Sakala, Corry, Applebaum, & Herrlick, 2013). Only 10% of U.S. women have a vaginal birth after cesarean, as opposed to another cesarean (National Center for Health Statistics, 2013). Barriers to VBAC remain firm.

Those barriers often include one-sided counseling to women of the risk of uterine rupture in a VBAC. Rarely are they told of the complication rates of accreta, which are higher across several measures. This is true when we look at maternal mortality (7% vs. 0%) (ACOG, 2012; Guise, et al., 2010), blood transfusion (54% vs. 12%) (Eshkoli, Weintraub, Sergienko, & Sheiner, 2013; Barger, et al., 2012), cesarean hysterectomy (20-70% vs. 6%) (Eshkoli, Weintraub, Sergienko, & Sheiner, 2013; Barger, et al., 2012), and maternal ventilation (14% vs. 3%) (Eshkoli, Weintraub, Sergienko, & Sheiner, 2013; Barger, et al., 2012). Further, 5.8% of accreta babies will die within the first week of life (Eshkoli, Weintraub, Sergienko, & Sheiner, 2013) in comparison to 2.8 – 6.2% of uterine rupture babies (Guise, et al., 2010).

Accreta results in higher rates of mortality and morbidity because it requires a complex response which most hospitals are not equipped to provide. A 2012 study advises, “Treatment of placenta accreta is best accomplished in centers that have the expertise to handle the management, which involves multiple disciplines, including blood bank, interventional radiology, anesthesia, and surgical expertise, gynecologic oncology, urology, or obstetric subspecialty expertise” (Heller, 2013).

It ís worth noting that uterine rupture does not require this level of response in order to generate a good outcome. As Aaron Caughey, OB-GYN and Chairman of the Department of Obstetrics and Gynecology at Oregon Health & Science University in Portland explains, “From an obstetrician standpoint, there are no particular special skills to managing a VBAC. Even in an emergency situation, we all have the surgical skills to deal with it” (Reddy, 2014).

Because some hospitals are not equipped to manage an accreta, some women who are diagnosed prenatally find themselves traveling hundreds of miles away from their family in order to deliver with accreta specialists.

At 19 weeks pregnant, Dawn was diagnosed with percreta, the most severe form of accreta where the placenta goes through the uterine wall and attaches to other structures in the abdominal cavity. She had nine prior pregnancies. Dawn was among the 93% of women who were never informed of the risks of accreta when she was pregnant after her first, second, or third cesarean (Kamel, 2014). All she heard were the dangers of VBAC. Thus, she had three cesareans.

When she got pregnant again, she heard the word accreta for the first time upon her diagnosis as is the case in 59% of women diagnosed with accreta (Kamel, 2014). Dawn ultimately traveled from her home in rural Virginia to Houston, Texas, at 27 weeks pregnant, to the Fox-Texas Children’s Pavilion for Women, an accreta specialty center. Due to complications related to her precreta, her son was delivered by cesarean hysterectomy at 33 weeks. Her son spent 19 days in the NICU before they could return back home to Virginia (personal communication, March 30, 2014).

It’s because accreta is so dangerous, complex to treat, and unknown to the general public, that professionals and researchers are sounding the alarm about the risk exchange that happens when repeat cesarean is chosen (or forced) over VBAC. As Dr. Elliot Main, Medical Director of the California Maternal Quality Care Collaborative, cautions, “In California, we are seeing a lot of hysterectomies, accretas, and significant blood loss due to multiple prior cesareans. Probably the biggest risk of the first cesarean is the repeat cesarean” (Main, 2013). (The state of California has a 9% VBAC rate, just a point below the national rate) (State of California Office of Statewide Health Planning and Development, 2013). A 2009 study from the Netherlands advises, “Ultimately, the best prevention [of uterine rupture] is primary prevention, i.e. reducing the primary caesarean delivery rate. The obstetrician who decides to perform a caesarean has a joint responsibility for the late consequences of that decision, including uterine rupture” (Zwart, et al., 2009). And a 2012 study warns, “Because cesarean delivery now accounts for about one-third of all deliveries in the United States, rates of abnormal placentation and subsequent hysterectomy will likely continue to rise” (Bateman, Mhyre, Callaghan, & Kuklina, 2012). By reducing the primary cesarean rate and increasing access to VBAC, we could also reduce the incidence of accreta, cesarean hysterectomy, and hemorrhage.

Following multiple uterine rupture lawsuits in the 1990s, some hospitals crafted their restrictive VBAC policies around litigation fears. However, the concern over lawsuits resulting from “VBAC gone wrong” may soon be overshadowed by the worry of being sued when women or babies die from accreta, after failing to adequately respond to this dangerous condition and/or denying access to VBAC (Associated Press, 2013; Children to sue hospital over death of mother, n.d.). This will certainly become the case as the public becomes more aware of the connection between VBAC bans, cesareans, and accreta.

It could also become a public relations nightmare as Americans begin to realize that litigation fears–not patient safety, drive hospital policy. This becomes more likely as more women are diagnosed with accreta.

As mothers are the ones who carry the risk of either uterine rupture or accreta, shouldn’t they be the ones deciding which set of risks are tolerable to them? As ACOG (2010) says, “the ultimate decision to undergo [planned VBAC] or a repeat cesarean delivery should be made by the patient in consultation with her health care provider” –  not by hospital administrators, malpractice insurance companies, or providers who simply don’t want to deal with VBAC.

As Dr. Howard Minkoff (2010) shared at the 2010 NIH VBAC Conference, “We should be starting with a sense of what’s the best interest of the mother. Unfortunately, the decision here is not always who are better equipped, it’s more like who are willing. There are a lot of hospitals that are quite capable of providing VBACs but exercise an option not to do it particularly if there’s someone nearby that will take that on for them.”

Hospitals around the country, and particularly those that are located in areas where VBAC bans mean that all women have repeat cesareans, are seeing and will continue to see increasing numbers of accreta. They have no choice but to manage it – which can be especially problematic for smaller facilities in rural areas that don’t offer the sophisticated response accreta requires.

But motivation remains the driving factor in hospital VBAC policy even in rural hospitals. Take the five small community hospitals in New Mexico that serve the Navajo Nation. As Dr. Jean Howe (2010), their Chief Clinical Consultant for Obstetrics, shared at the 2010 NIH Conference, these rural facilities collectively deliver 3,000 babies each year and maintain a 15% cesarean rate and a 38% VBAC rate. Numbers like that just don’t happen. They are the result of motivated administrators, providers, and patients who want VBAC to be an option at their facility.

The bottom line is, VBAC bans simply delay risk. The sooner hospital administrators and the American public realize this, the sooner we can mobilize–reducing future risks of accreta by making VBAC a viable option in more hospitals. It is one thing for a woman to knowingly plan a repeat cesarean understanding this risk. That is her choice as both VBAC and repeat cesarean come with risk. However, it is unconscionable when a woman is not presented with her options and she develops accreta in a subsequent pregnancy.

As the American public becomes more aware of the serious risks associated with repeat cesarean, will more providers and facilities be sued as a result of accreta-related complications and death? Will it have to come to fear of litigation, again, in order for hospitals to throw aside their current VBAC bans, listen to what the NIH, ACOG, and the medical research has to say; to create an environment that is supportive of VBAC, respect a mother’s right to make her own medical decisions, and prepare accreta-response protocols?

Women are entitled to understand what that first cesarean means in terms of their future birth options and their long term health. Consumers and providers should work with hospital administration to reverse VBAC bans, review current VBAC policies to insure they are aligned with national guidelines and evidence, and improve response times for obstetrical emergencies through team training and drills (Cornthwaite, Edwards, & Siassakos, 2013). Providers should have frank conversations with patients about the immediate and long-term risks and benefits of their options within the context of intended family size, acknowledging that sometimes the stork delivers when you’re not expecting it. This is about administrators, providers, professionals, and consumers working together for better processes and healthier outcomes. Let’s get to work.

Practice Variation in Cesarean Rates: Not Due to Maternal Complications

November 13th, 2014 by avatar

By Pam Vireday

Pam Vireday, an occasional contributor to Science & Sensibility reviews the recent study by Katy Kozhimannil, PhD and colleagues that examined the differences in cesarean rates between over a thousand hospitals in the USA.  Consumers of maternity care quite possibly do not realize what a significant impact their choice of facility (and provider) may have on their birth outcome.  Can you think of hospitals in your own community serving similar populations of pregnant families that have drastically different cesarean rates.  Have you considered why that might be?  Do you think that the families you work with have explored this too?  Do they even have access to this information?  Read Pam’s discussion of this recent study below.  – Sharon Muza, Community Manager, Science & Sensibility.

There’s a new study out that discusses the variation in cesarean rates between hospitals in the United States. “Maternal clinical diagnoses and hospital variation in the risk of cesarean delivery: Analyses of a national US hospital discharge database” was released late last month and has received a lot of press and discussion ever since.

Practice variation is a serious problem in obstetrics (Arcia 2013). Women are often far more at risk for a cesarean in certain hospitals than in others, even when the hospitals serve the same geographical area and population (Arnold, January 2013 and August 2012).

Of course, care providers protest that some hospitals have higher cesarean rates because they serve higher-risk patients. This is a valid point, but it still doesn’t explain the wide variation in rates between many hospitals (Clark 2007).

For example, in a press release about the new study, the mother’s risk status and diagnoses did not explain the variation in cesarean rates between hospitals:

“We found that the variability in hospital cesarean rates was not driven by differences in maternal diagnoses or pregnancy complexity,” said [lead study author] Kozhimannil. “This means there was significantly higher variation in hospital rates than would be expected based on women’s health conditions. On average, the likelihood of cesarean delivery for an individual woman varied between 19 and 48 percent across hospitals.”

Other key points highlighted included:

  • Among lower risk women, likelihood of cesarean delivery varied between 8 and 32 percent across hospitals.
  • Among higher risk women, likelihood of cesarean delivery varied between 56 and 92 percent across hospitals.
  • Hospital variability did not decrease after adjusting for patient diagnoses, socio-demographics, and hospital characteristics.

This shows that practice variation in cesarean rates is real, substantive, and not just a reflection of the mother’s risk level. 

Perhaps now we can stop playing the mother blame-game when we talk about cesarean rates? (Declerq 2006, Oganowski 2011)

This study is not the first to show that the culture of a hospital, its policies, and its routine practices all help determine how likely a woman is to “need” a cesarean in that hospital.

For example, Cáceres 2013 found that even after adjusting for socio-demographic and clinical factors and including only NTSV (Nulliparous, Term, Singleton, Vertex) pregnancies, the cesarean rate varied significantly between Massachusetts hospitals, “suggesting the importance of hospital practices and culture in determining a hospital’s cesarean rate.”

In addition, a 2014 consensus statement from the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine notes, “Variation in the rates of nulliparous, term, singleton, vertex cesarean births also indicates that clinical practice patterns affect the number of cesarean births performed.”

Preventing cesareans when possible is important because while cesareans can be life-saving at times, they present more risk for maternal infection, bleeding and blood clots, and more neonatal breathing problems (Liu 2007, Visser 2014).

Notably, a large case-control study in U.K. maternity units found that delivery by cesarean was a strong risk factor for severe sepsis (Acosta 2014). Other research has found a high rate of maternal complications (Pallasmaa 2010) and poorer neonatal outcomes (Kolås 2006) associated with cesareans.

In addition, a cesarean’s potential negative effect on future pregnancies is important (Silver 2012). One American study found that the rate of an abnormal placental attachment increased in conjunction with the rise in cesarean delivery rate (Wu 2005), while a Canadian study found that a prior cesarean was associated with an increased risk for adverse neonatal outcomes in subsequent pregnancies (Abenhaim and Benjamin 2011).

Bottom line, it matters where and with whom a woman gives birth in order to lessen the risk for complications, both now and in the future.

But many women naively choose their care provider for pregnancy based mostly on convenience and location, not realizing that their chances of surgical birth may vary greatly depending on which hospital and caregiver they use (Arnold 2014, Arnold January 9 2013).

Childbirth Connection, a leading consumer education site, points out:

Research suggests that the same woman might have a c-section at one hospital but a vaginal birth if she gave birth at another, just because of the different policies and practices of those hospitals. One of the most effective ways to lower your chance of having a c-section is to have your baby in a setting with a low c-section rate.

Yet it is not always easy to find out the cesarean rates of local hospitals in some areas. For example, the health departments of Missouri, South Carolina, and Washington D.C. do not make hospital-level cesarean rates available to consumers.

Hospitals remain largely unaccountable for high cesarean rates, although we are beginning to see marginal progress in some places towards more accountability (Gentry 2014 and Dekker 2014). In the meantime, however, thousands of women are undergoing cesareans, many of which might be preventable with changes in clinical practices (Boyle 2013).

And even when a cesarean is truly necessary, there can be large discrepancies in complications afterwards between hospitals (Alonso-Zaldivar 2014). It’s not just about how many cesareans are done, but also about which hospitals have the best outcomes when a cesarean is done. Without more information, how is a woman to know which hospital to choose?

Bottom line, more transparency and accountability are needed. As the lead author of the study states:

Women deserve evidence-based, consistent, high-quality maternity care, regardless of the hospital where they give birth…and these results indicate that we have a long way to go toward reaching this goal in the U.S.

Do you ever encourage your students and clients to look at the cesarean rates (and rates of other interventions which may lead to cesareans) of the hospitals they are considering birthing in.  Please share your experience in our comments section. – SM
