Nice Is Not Enough: Questions for Interviewing a Maternity Care Provider

Many women want to choose their pregnancy care provider carefully, but aren't sure what questions to ask when interviewing doctors or midwives. 

Here are some general questions that some care providers* have suggested asking any provider you are considering during your pregnancy and birth.
  1. How do you define “normal birth”?
  2. Can you give me an example how you typically manage a normal birth?
  3. How would you feel if I disagreed with you about a procedure you recommended during labor or birth?
  4. How long will you “allow me” to wait if I go overdue?
  5. What position(s) will you allow me to use when giving birth?
  6. How do you feel about IVs and continuous fetal monitoring?
  7. How do you feel about a woman eating and drinking in labor?
  8. What are your thoughts on pain relief in labor?
  9. How do you feel about cesareans?
Some childbirth educators would substitute different questions here and there from this list but it's a reasonable basic list to start with. Adapt as necessary for your own personal situation and concerns.

Also pay close attention to the provider's response to your questions. Of course, care providers have limited amounts of time to answer questions at most visits so it's important to be considerate and concise when you ask questions, but if they are impatient with your questions or dismissive of your concerns, that's a sign you might want to look elsewhere.

There are other additional questions you might want to ask if you are a woman of size, but more on that in future posts. If anything, women of size need to be even more vigilant in asking questions of potential care providers because size bias is so prevalent in maternity care. But for now, the above questions are a reasonable start to the process.

Sample Answers to These Questions

So what are reasonable answers to the above questions? It really depends on the type of birth you are looking for and how interventive you want your care provider to be.

Some people want a totally natural birth, and some want all the interventions and machines that go PING that technology can give them. Neither approach is right or wrong; it's more a matter of what you prefer and the unique needs of your pregnancy.

However, it's far more difficult to find a provider truly supportive of natural birth than a provider that routinely uses lots of technology and interventions. So the slant of this post is going to lean more in the direction of finding someone supportive of natural birth, but readers should not infer any judgment of their own personal preferences. Again, adapt the questions to your own personal needs and preferences.

1. How do you define "normal birth"? 

To some care providers, "normal" birth means just about anything (including significant amounts of interventions), whereas to others it means an undisturbed, spontaneous labor resulting in a vaginal birth without any interventions. You can get some idea of a care provider's attitude towards birth and interventions by what they think of as "normal" in birth.

2. Can you give me an example how you typically manage a normal birth?

To some care providers, typical management includes inducing labor at 39 or 40 weeks, mandatory IV, epidural by 4 cm dilation, and active management of care (breaking the waters early in labor, aggressive management of contractions with oxytocin, etc.). To other care providers, induction is used only when medically indicated (concern over blood pressure, baby not growing well, etc.), IVs are not mandatory, epidurals are completely up to the mother's choice, and routine interventions in labor are not utilized unless medically indicated.

Again, neither is inherently right or wrong, just different ways of looking at and managing labor. By asking the question of how the care provider typically manages normal birth, they can begin to understand where the caregiver falls on the continuum of intervention.

3. How would you feel if I disagreed with you about a procedure you recommended during labor or birth?

This is an important question because it speaks to the caregiver's respect for patient autonomy and how they prefer to interact with patients. Some care providers never want their dictates questioned. Others give education on the pros and cons of procedures and make strong recommendations based on their training and knowledge, but respect the mother's right to choose for herself.

It's important to also point out that women vary greatly in their desire for informed decision-making. Some prefer to leave all the decision-making up to the care provider and don't want to be "burdened" with having to make those choices. Others want to be very involved in the decision-making. The question is designed to help you figure out which style of care you prefer, and whether that aligns with the care style of the provider you are interviewing.

4. How long will you "allow me" to wait if I go overdue?

There is a great deal of controversy about the safest time for women to go into labor. There is a small but significant risk for stillbirth as gestational age increases, but this risk has to be weighed against the significant risks of inducing labor earlier, which may increase the risk for harm from strong drugs or may increase the risk for cesarean. Current research varies quite a bit on whether a pregnancy should be induced to lower the risk for stillbirth or other poor outcomes. There is no "right" answer here, only an answer that reveals to you what your care provider routinely does.

Many care providers induce labor right at 39 or 40 weeks, some wait till 41 weeks, some wait till 42 weeks, some wait even longer as long as the baby's status is reassuring. Some prefer inducing earlier but will respect the mother's decision to wait if baby looks okay. The point is to know your care provider's preferences on this very important point and to explore how flexible they are about it.

5. What position(s) will you allow me to use when giving birth?

Most hospital births occur with the mother either flat on her back, propped up with her legs in stirrups, or with the mother pulling back on her knees ("supine" or "lithotomy" positions). This is our cultural expectation of birth, and nearly all media images of birth show this position.

In other cultures, however, many other birth positions are used, including kneeling, squatting, side-lying, hands-and-knees, and asymmetrical positions, and these labor positions have distinct advantages. Some providers are very comfortable allowing the mother to labor in positions like these, while other providers restrict the mother to only the typical hospital positions. The question is designed to help you find out how your provider feels about birth positions.

Be careful how you word the question, though. Many care providers tell you that they will "let" you labor in whatever position you want, but fail to reveal that when it comes time to actually push out the baby they want you in the usual positions. Many providers are extremely uncomfortable attending a birth in a position other than supine or lithotomy and will pressure you to change positions, even though there is quite a bit of evidence for the benefit of upright and other positions in birth.

Some women don't care about what position they give birth in or are uncomfortable experimenting with different positions. Others are adamant about having the freedom to move as their bodies dictate, especially as the baby emerges. The important thing is to find a provider that is comfortable with your preferences, so be sure to ask ahead of time about not only labor positions, but also what position they want you in for when the baby is actually coming out.

6. How do you feel about IVs and continuous fetal monitoring?

It is important to establish your provider's preferences about routine interventions like IVs and continuous fetal monitoring.

Some providers are fine with women laboring without an IV. Others mandate an IV for all their patients, while still others strike a middle course and only request that a heplock be placed so that emergency access would be faster if an IV became needed.

Although continuous fetal monitoring has not been shown to improve outcomes in low-risk women, it is still extremely common in nearly all hospitals. However, some providers are more flexible than others about when it starts, whether intermittent monitoring can be used instead, and whether mobile monitoring is allowed.

7. How do you feel about a woman eating and drinking in labor?

Some care providers and hospitals have strict rules about whether a woman is "allowed" to eat food or drink during labor, despite a lack of evidence showing harm from this practice. Many allow only ice chips to be used during labor. It is important to understand your caregiver's policies before labor.

8. What are your thoughts on pain relief in labor?

Women vary greatly in their wishes towards pain relief during labor. Some prefer to go natural, some want an epidural "in the parking lot," some would rather take a wait-and-see-if-it's-needed approach.

Some care providers are very respectful of a woman's wishes about pain management in labor. However, some practically mandate that all their patients receive an epidural, while others can be judgmental about any use of pain medications. Still others know many "tricks" to help women lower their need for pain relief in labor but are supportive of whatever the woman chooses at the time.

Respect for one's wishes regarding pain management during labor plays a strong role in women's satisfaction with their birth experience. It is vitally important to find a care provider who is aligned with your preferences and who will be supportive of your choices.

9. How do you feel about cesareans?

Some providers truly believe that vaginal birth is dangerous and that cesarean birth is to be preferred. Others believe that cesareans are to be avoided at virtually any cost. Most providers fall somewhere in between, but most tend to "lean" one way or the other. Obviously, every caregiver is supportive of cesareans when they are truly life-saving but their attitudes towards other cesareans (and the current cesarean rate in first-world countries) can be revealing about their underlying philosophies of birth and likelihood to use a cesarean.

Beware: Nice Is Not Enough

Don't let a care provider's bedside charm and personality supercede your own commonsense about interventions. A care provider can be really charming, caring, and nice and still have a 50+% c-section rate and a 40+% episiotomy rate, which will do far more harm than good in the long run.

Just because they are "nice" doesn't mean you are going to get care from them that doesn't put you at risk for more complications. 

One midwife told the story of the following doctor on her blog:
What is the definition of a “good doctor”? I once knew a physician whom everyone believed was a “good doctor”. Let’s call him Dr. Wonderful. He had a very high cesarean rate, a high episiotomy rate, a high forceps/vacuum rate, and yet his patients adored him. Why?
He made each woman who came to him feel special. He was handsome and charming, and would treat each woman as if she were the only patient in the world that mattered to him. This is not necessarily a bad thing–I believe each patient should feel special and important to her provider. However, when this perception of being special clouds a woman’s judgment, it is time to have a reality check.
Dr. Wonderful would visit his patient after whatever unnecessary procedure he did, sit by the bedside, take her hand, and very regretfully tell her how sorry he was that she needed ___________ (insert the procedure of your choice), but if he had not done it, ___________ would have happened (insert catastrophe of your choice). So he very reluctantly had heroically intervened to save her life, or the life of her baby. The woman would be trembling with gratitude toward this marvelous physician by the time he left the room. None of his patients could ever believe that any of these procedures were unnecessary.
This bait-and-switch tactic is very common among some care providers. They know how to manipulate patients into going along with what they think is best and/or what is most convenient, even when the actual research doesn't support these interventions as best practice. 

Most women think that if their doctor recommends a procedure to them, it must be necessary, and who are they to question the doctor's judgment? But most don't realize how much interventions vary from caregiver to caregiver. Nor are most given adequate information about the pros and cons of most procedures.

The point is not that all interventions are "bad" or must be avoided, but that the benefits and risks of proposed interventions should be discussed thoroughly and true patient autonomy respected, not manipulated. 

If you are sure you want a hospital birth but you'd like to try and find a provider who is more friendly to natural childbirth and patient autonomy than most, the midwife above summarized one strategy for scoping out the possibilities:
I suggest that women who are planning hospital birth call their local [Labor and Delivery] unit, and ask to speak to a nurse who enjoys helping women who want unmedicated birth. Then ask that nurse for names of doctors [or midwives] that she thinks are most likely to support you in your goals.
Last, and perhaps most important, don’t be fooled by a charming bedside manner. Make sure there is substance behind it.
Amen to that. "Nice" is wonderful, but some care providers use it as a way to convince women into all kinds of risky interventions as a way to lower the risk for being sued or because it's more convenient for him/her. 

In particular, many women of size are just so grateful just to find a doctor who doesn't yell at them about their weight that they fail to ask further questions about the provider's rates of interventions that increase the risk for cesarean (a high induction rate, inducing for suspected big baby, etc.). 

I've been there done that myself and gotten burned, so learn from my mistakes.

Don't fall for "nice" over substance. Nice is a good start, but you still have to ask further questions.

Ask for Specific Intervention Rates

It's really important to ask a provider's intervention rates, especially his/her intervention rates for first-time moms.

What's his/her induction rate, cesarean rate, episiotomy rate? 

Also observe how the provider responds to questions about these things. That's as telling as the actual intervention rate.

For example, "I only do them when necessary" is not a helpful answer; for some docs, interventions like these are seen as "necessary" 60% of the time, and that rate presents far more risk than benefit. 

For example, episiotomy rates should be quite low; if it's not, the provider is not practicing evidence-based medicine, which has clearly shown routine episiotomy to be more harmful than helpful

Many doctors say they "only do episiotomies when necessary" --- but if they find it "necessary" 40% of the time, there is something wrong with their definition of "necessary."

Moral of the story: Actual numbers are important for evaluating a provider.

Primary cesarean rates (cesareans in first-time moms or mothers who have never had a cesarean before) is another benchmark by which you can judge providers. Women who have not had cesareans before should not have a very high rate of cesareans during labor; if they do, it suggests that the doctor has a low threshold for surgery or encourages a lot of interventions that lead to more cesareans.

(Of course, if a provider regularly provides care to many high-risk women, the cesarean rate is going to be higher than a provider who mostly sees only low-risk women.....but generally speaking a high cesarean rate is a red flag.) 

It's also helpful to ask how the care provider feels about cesareans. 

If they have a high cesarean rate but are defensive about that, they'll likely say something that minimizes the impact of cesareans and ridicules the mother for caring. 

Watch out for comments like, "The real priority is a healthy baby" or "A healthy baby is more important than the delivery method".....as if that justifies any intervention the doctor uses, as if the mother's outcome is of no importance, and as if the mother questioning things means she doesn't really care about her baby over herself.

Of course the priority is a healthy baby, but a healthy mother is also a priority, and one recovering from unnecessary surgery is not a healthy mother. Nor should a woman be ridiculed for caring about avoiding a cesarean or an episiotomy whenever possible. 

A provider that avoids the question of intervention rates by blaming the mother, brushing off her concern, or making her feel selfish for caring is a giant red flag.

Beware care providers that "don't know" their cesarean rate, or who subtly deride anyone who asks questions about cesarean or episiotomy rates. All providers should have a general idea of their cesarean and episiotomy rates. If they don't, that suggests that they don't think these rates are important or aren't concerned about their use.

Also ask when/why the provider would want to induce labor. If they routinely induce labor if the baby is thought to be  "big," that's another tremendous red flag.  Research shows that inducing early for a "big baby" actually increases the cesarean rate, but despite the evidence, many providers still induce early for a big baby anyway.  [This is one major factor driving the high rate of cesareans in women of size.]

If you interview a provider and they would induce early for a big baby, this is a huge red flag.

Many providers also routinely induce labor at 39, 40 or 41 weeks, and research is mixed on the pros and cons of this practice

Particularly for women of size (whose pregnancies tend to last longer), inducing labor early or right around term "just in case" probably leads to more cesarean risk and a whole host of other potential complications. You may want to find a provider who is more willing to wait and not rush things as long as mother and baby are doing well.

Conclusion

You can have the "nicest" doctor or midwife in the world, and he or she can still coax you straight down the path to a cesarean or episiotomy you don't need by engaging in unnecessarily high rates of interventions with dubious benefits.

Being nice is just not enough. You have to ask careful questions when interviewing a care provider, you have to ask for specific intervention rates, and it's very important to watch for the classic red "alarm" flags.

What questions were most helpful to you when you were interviewing providers? What questions do you wish you had asked? What advice do you have for other pregnant women looking for maternity care providers?


*July 2014 Update: These questions were originally shared in a much longer article ("In Search of Dr. Right: 11 Questions to Ask" by The Midwife Next Door) on another website, and I gave credit and linked to that article in my original post in 2010. Sadly, the original link has since been compromised and now goes to an extremely undesirable site, so I have stripped out all those links and am re-posting this article without them. The questions are helpful so I am keeping the post; but it's important to note that it originally arose from another's work.

Midwives Can Safely Care for Obese Women

Image Credit: Andy Ellison
In many places, midwives are no longer permitted to care for obese women, or at least obese women over a certain BMI (often 35 or 40). 

Many women of size these days are "risked out" of midwifery carehomebirthbirth centers, waterbirth, and even some hospitals. Some OBs are even refusing to see obese patients at all. A fat woman's only choice for care may become a high-risk specialist, even if she is healthy and has no complications.

I've written about this before. I call it Ghettoizing Women of Size.

It is done based on hyperbole around the risks of obesity and does not reflect the fact that many obese women are healthy, do not develop complications, and do just fine with midwifery or other "alternative" care. 

In the following recent Dutch study, although more obese women had their care transferred to OBs (some of which could simply represent bias or exceeding BMI cutoffs rather than actual complications), the obese women who were cared for by midwives had no more adverse outcomes than other women.

This shows that, providing there are no major complications, obese women (and even "morbidly obese" women) can be safely cared for by midwives.

There is no need for automatic transference of care, and definitely no need for routinely ghettoizing obese women into high-risk, high-intervention care.

*Midwives, let's see some more formal studies of midwifery care of obese women. Personally, I'd love to see a study comparing outcomes of healthy obese women routinely assigned to OB care and those routinely assigned to midwifery care. 



Reference

BJOG. 2014 Mar 12. doi: 10.1111/1471-0528.12684. [Epub ahead of print] The impact of obesity on outcomes of midwife-led pregnancy and childbirth in a primary care population: a prospective cohort study. Daemers D1, Wijnen H, van Limbeek E, Budé L, Nieuwenhuijze M, Spaanderman M, de Vries R. PMID: 24618305
OBJECTIVE: To assess the impact of obesity on the likelihood of remaining in midwife-led care throughout pregnancy and childbirth. DESIGN: Secondary analysis of data from a prospective cohort study. SETTING: Dutch midwife-led practices. POPULATION: A cohort of 1369 women eligible for midwife-led care after their first antenatal visit. METHODS: First-trimester body mass index (BMI) was calculated as weight measured at booking divided by height squared. Obstetric data were retrieved from medical records. Multiple logistic regressions were performed to examine the effects of BMI classification on midwife-led pregnancies and childbirths. MAIN OUTCOME MEASURES: Percentages of women remaining in midwife-led care throughout pregnancy and throughout childbirth. RESULTS: Of women in obesity classes II and III, 55% remained in midwife-led care throughout pregnancy and 30% remained in midwife-led care throughout birth. Compared with women of normal weight, women in obesity classes II and III had fewer midwife-led pregnancies (OR 0.38, 95% CI 0.21-0.69), and women who were overweight or in obesity class I had fewer midwife-led childbirths (OR 0.63, 95% CI 0.44-0.90; OR 0.49, 95% CI 0.29-0.84, respectively). Compared with women of normal weight, women who were obese had higher referral rates for hypertensive disorders (4 versus 14%), prolonged labour (4.6 versus 10.4%), and intrapartum pain relief (4 versus 10.4%). The women who were eligible for midwife-led birth and who were overweight or obese, had no more urgent referrals than women of normal weight. Women who were obese and who completed a midwife-led birth had no more adverse outcomes than women of normal weight, with the exception of higher rates of large for gestational age (LGA) babies (>97.7 centile; 12.1%, versus 1.9% in normal weight and versus 3.3% in overweight women). CONCLUSIONS: Although fewer women who were obese remain in midwife-led care during pregnancy and childbirth, there was no increased risk of unfavourable birth outcomes for women who were obese and eligible for a midwife-led birth when compared with women of normal weight. This indicates that when primary care midwives use a risk assessment tool throughout pregnancy and childbirth they are able to safely assign women who are obese to either midwife-led or obstetrician-led care.

CesareanRates.com: Transparency in Maternity Care

www.cesareanrates.com 

There's a new website out that I've been wanting to highlight for a while.  Now, as the author struggles to finance her work on the site, it's even more important that I publicize the site.

The site is called cesareanrates.com and it has the cesarean rates for most of the states in the U.S. and the provinces in Canada.

Most importantly, not only does it have the cesarean rates by state/province, it also has the cesarean rates by individual hospital.

Earthy-birthy types who read my blog probably already know about this wonderful resource, but others may not.  It makes for very interesting reading and I recommend the site.

Having cesarean rates available by hospital is incredibly useful information.  If you live in an area where you have the choice of more than one hospital, you can see which ones have very high baseline cesarean rates and which ones don't.

Such information has to be interpreted with caution, of course, since some hospitals have higher loads of high-risk patients who might be expected to have higher cesarean rates. This is a legitimate concern.  However, even among hospitals that serve higher-risk patient populations, cesarean rates can vary widely. So while caution has to be used when viewing this data, it still can be useful to the consumer.  Some hospitals really do have a strong climate of overutilization of cesareans, and consumers should have access to that information before choosing to become a customer of that hospital.

So let's talk a little bit more about the variations in cesarean use and the importance of transparency in cesarean rates for quality control purposes.
Image Use Disclaimer: I received express permission from creator Jill Arnold of The Unnecesarean to use the cesareanrates.com images. If you want to use them, please ask her permission first.
Variations in Cesarean Utilization

One of the attitudes we have to fight against all the time in Cesarean Awareness advocacy is the common public perception that cesareans are only done when necessary.  In other words, most people assume that if a woman had a cesarean, it was usually because she needed it and it saved her or her baby's life.

Yes, cesareans can be life-saving, and there is no doubt that having them available is a wonderful thing.  Absolutely no argument there.

However, while cesareans mostly used to be used only when truly needed, there are many cesareans being performed today that are not medically indicated.  And the strong regional variations in cesarean use just reinforce this.

Below is a chart from Jill's site of the ten hospitals with the highest c-section rates in Florida.


Now look at a chart from Jill representing the ten hospitals with the highest c-section rates in Utah.


So the hospital with the highest cesarean rate in Florida has a rate TWICE as high as the hospital with the highest cesarean rate in Utah.

Come on, are the uteri of women in Utah really that much more efficient as the uteri of women in Florida? No, of course not.  The fact is that cesarean rates are highly variable by region, by hospital, and by doctor, and many of these variations are not explainable by demographic differences or risk caseload.

Even within one regional area with similar demographics and patient risk profiles (and eliminating cesareans for indications like breech, thought to be "necessary" by some providers), cesarean rates can vary widely.


While doctors like to blame women for high c-section rates (the overused "women are too old or too fat" or "women are requesting these cesareans" arguments), the truth is that provider practice patterns have far more influence on cesarean rates than factors attributable to women themselves.

The Childbirth Connection, an organization devoted to improving maternity care, confirms this trend:
The cesarean rate varies broadly across states and areas of the country, hospitals, and maternity professionals. Most of this variation is due to "practice style" rather than differences in the needs and preferences of childbearing women.
In other words, your chances of "needing" a cesarean at one hospital in your area may be quite different than your chances of "needing" a cesarean in a different hospital in your area.  Even if you fall into a supposedly "high-risk" category, your chances of "needing" a cesarean can vary widely, depending on who you see and their practice patterns around birth.

While some cesareans truly are prudent and at times even life-saving, many cesareans performed today are not.  Women deserve to know which hospitals have high rates of cesarean utilization and which do not, so that they can make informed choices about where they go to birth, should they choose to have a hospital birth.

Caveats

I would like to tell you that hospital-level cesarean rates area available for all 50 states, but alas, that's not true.  Last I checked Jill's site, the following states did not have hospital-level information about cesarean rates available:
Why is this information not available uniformly? The reasons vary. Some states don't think consumers are interested in this information and so don't provide it. Or pencil-pushers decide that providing cesarean rates to the public is not a Department of Health budget priority.  A few states have decided that health consumers have no right to this information and refuse to release hospital-level cesarean rates, despite many requests to do so.

There is information in each of the links above on how to contact these states directly to request that this information be made public.  Sometimes, if a state gets enough requests, they make providing hospital-level cesarean rates more of a priority.  (We were able to do this recently in my state.)

On the other hand, sometimes states actively refuse to provide hospital-level cesarean rates because doctors have actively campaigned to keep these rates private, on the grounds that the public is not smart enough to understand the concept of mitigating factors (like a high-risk caseload, etc.).  Or they simply don't want the bad publicity for their hospitals.

This is ridiculous.

As health consumers, we deserve to have public health information about various hospitals and their quality of care.  And we deserve this information for maternity-related care as well as basic overall care.  

The Importance of Transparency

Transparency is a HUGE up-and-coming issue in healthcare.  As one quality watchdog group notes:
You may not realize there are differences in the quality of care provided by different hospitals. Hospitals are busy and complex places. Every day, hundreds of patients are receiving hundreds of different procedures. Medical mistakes are a leading cause of death each year, causing more deaths each year than car accidents, breast cancer and AIDS. 
There is good news! Hospitals can take steps to prevent mistakes and protect patients from unnecessary injury. Even better, there is information available to help you determine the quality of your local hospitals.
More and more, groups such as consumerreports.org and the Leapfrog Group have begun to document basic information on Quality of Care measures, such as which hospitals have high rates of hospital-acquired infections, which have poor overall patient safety, and which have high rates of medical mistakes or medication errors.

However, these quality monitoring efforts are in their infancy.  Some hospitals participate voluntarily, but some actively resist any attempt to shine a spotlight more closely on care practices. Yet experience shows that when substandard results are highlighted and a program is developed to address these issues, outcomes can be improved.

It is important to be careful when comparing results from different hospitals, but even with this caution in mind, transparency in Quality of Care measures can be useful in improving care and patient outcomes.

Transparency and Participatory Medicine are concepts whose time has come.

How does this translate to maternity care?  In maternity care, substandard care translates to high rates of maternal or neonatal infections, high rates of early scheduled deliveries, higher-than-average deaths, and a too-high cesarean rate.

Some hospitals would argue that a high cesarean rate is not a sign of substandard care. The World Health Organization disagrees, noting that high rates of non-medically indicated cesareans translate into a higher rate of adverse maternal outcomes, including admission to Intensive Care Units, blood transfusions, hysterectomies, and maternal deaths. Other risks include blood clots, wound infections, anesthesia accidents and other problems.  Clearly, overuse of cesareans has risks.

There is an ongoing argument over what the "most optimal" cesarean rate should be, but that's beside the point.  Whatever the "ideal" rate is, women deserve to know the baseline cesarean rate of their hospital of choice, and how that compares to other hospitals.  Then it is up to them which hospital they choose.

Final Thoughts

CesareanRates.com is a powerful new tool for healthcare consumers.

One of the many useful things on the website is the listing of the cesarean rates of all the U.S. states (both alphabetically and by highest-to-lowest rates). There is also a graph showing the increase in cesarean rates over time in the U.S.  Rates from the Canadian Provinces are available as well.

I like the Top Ten slideshow, where slides from several representative states list the hospitals with the highest cesarean rates in those states.  You'll see that quite a few hospitals have c-section rates around 50%-60%, while other states' rates are not nearly so high. This is a good micro-demonstration of how much variation there can be in cesarean rates from hospital to hospital and state to state.  (Click on the page number on the bottom to freeze a particular state's slide.)

Another useful thing is a state-by-state listing of the VBAC ban policies of individual hospitals.  This information can already be obtained from the International Cesarean Awareness Network’s VBAC Policy Database but it's useful to have it all in one place with the hospital-level cesarean rates.

You can read more here about why Jill Arnold created this new site:
CesareanRates.com is a snapshot of online cesarean rate reporting in the United States as of January 2012. The site compiles the most current hospital-level data accessible to the public online, whether reported directly by a state’s department of health or gathered from state hospital association web sites via pull-down menus. The initial goals of the site are to a) show the (poor) quality and inaccessibility of hospital-level information available to the public, b) to assess whether there is public demand for this information and c) to work toward establishing a precedent for hospital data transparency.
How might this site be useful for a typical healthcare consumer?  Jill elaborates on that question here:
As with everything pregnant people can get their hands on, it is one of many tools. Everyone makes decisions differently and weighs things based on their unique experiences, values, preferences and education. For example, a 60% total cesarean rate might trigger a different reaction for different people. A woman that passionately wants to avoid an unnecessary cesarean section might be deterred from giving birth there, while one hoping for an elective primary section might infer something about the culture of the hospital and seek a provider that delivers babies there. Another person might try to evaluate what exactly that means and start investigating why it is so high, while someone else might not care one way or the other where they give birth as long as they are with a care provider they like. 
Ideally, it would be nice to see the site used by pregnant people for the purpose of seeking preference-sensitive care and opening up dialogue with their provider about what they can expect at the hospitals at which their provider has privileges.

There is enormous geographic variation in the use of cesarean delivery: For births over 2,500 grams, adjusted cesarean rates vary fourfold between low- and high-use areas. Even for births under 2,500 grams, high-use counties have rates that are double those of low-use ones. Higher cesarean rates are only partially explained by patient characteristics but are greatly influenced by nonmedical factors such as provider density, the capacity of the local health care system, and malpractice pressure. Areas with higher usage rates perform the intervention in medically less appropriate populations-that is, relatively healthier births-and do not see improvements in maternal or neonatal mortality.

OBJECTIVES: This study was undertaken to examine the national and regional rates of operative delivery among almost one quarter million births in a single year in the nation's largest healthcare delivery system, using variation as an arbiter of the quality of decision making. STUDY DESIGN: We compared the variation in rates of primary cesarean and operative vaginal delivery in facilities of the Hospital Corporation of America during the year 2004. RESULTS: In 124 facilities representing almost 220,000 births during a 1-year period, the primary cesarean and operative vaginal delivery rates were 19% +/- 5% (range 9-37) and 7% +/- 4% (range 1-23). Within individual geographic regions, we consistently found variations of 200-300% in rates of primary cesarean delivery and variations approximating an order of magnitude for operative vaginal delivery. CONCLUSION: Within broad upper and lower limits, rates of operative delivery in the United States are highly variable and suggest a pattern of almost random decision making. This reflects a lack of sufficient reliable, outcomes-based data to guide clinical decision making.

OBJECTIVE: To examine regional variations in rates of primary cesarean delivery and assisted vaginal delivery in the population of British Columbia, while adjusting for the maternal characteristics and conditions that increase the likelihood of operative delivery. METHODS: Using data from the British Columbia Perinatal Database Registry, we studied all deliveries in British Columbia between 2004 and 2007, excluding women who had a previous cesarean delivery (n=116,839)...RESULTS: Crude primary cesarean delivery and assisted vaginal delivery rates varied markedly across the Health Service Delivery Areas ranging from 16.1 to 27.5 per 100 deliveries, and from 8.6 to 18.6 per 100 deliveries, respectively. The most common indication for cesarean delivery was dystocia, which accounted for 30.0% of all cesarean deliveries and varied more than fivefold across regions. After controlling for maternal characteristics and conditions known to increase the likelihood of cesarean delivery and assisted vaginal delivery, adjusted cesarean delivery rates varied twofold, ranging from 14.7 to 27.6 per 100 deliveries, while adjusted assisted vaginal delivery rates varied by more than twofold, ranging from 6.5 to 15.3 per 100 deliveries. CONCLUSION: Our results illustrate substantial regional variation in the use of cesarean delivery that cannot be explained by patient illness or preferences. This variation likely reflects differences in practitioners' approaches to medical decision-making.

BACKGROUND: Studying populations with low cesarean delivery rates can identify strategies for reducing unnecessary cesareans in other patient populations...METHODS: We used a case-control design nested within a cohort of Native American live births, > or = 35 weeks of gestation (n = 789), occurring at an Indian Health Service hospital during 1996-1999... RESULTS: The total cesarean rate was 9.6 percent (95% CI 7.2-12.0). Nulliparity, a medical diagnosis, malpresentation, induction, labor length > 12.1 hours, arrested labor, fetal distress, meconium, and gestations < 37 weeks were each significantly associated with cesarean delivery in unadjusted analyses. The final multivariate model included a significant interaction between induction and arrested labor (p < 0.001); the effect of arrested labor was far greater among induced (OR 161.9) than noninduced (OR 6.0) labors. Other factors significantly associated with cesarean delivery in the final logistic model were an obstetrician labor attendant (OR 2.4; p = 0.02) and presence of meconium (OR 2.3; p = 0.03). CONCLUSIONS: Despite a higher prevalence of medical risk factors for cesarean delivery, the rate at this hospital was well below New Mexico (16.4%, all races) and national (21.2%, all races) cesarean rates for 1998. Medical and practice-related factors were the only observed independent correlates of cesarean delivery. Implementation of institutional and practitioner policies common to the Indian Health Service may reduce cesarean deliveries in other populations.

Induction Math: The Importance of the Bishop Score

Image from Relay Health, as displayed on http://www.med.umich.edu/

Yet another study shows that inducing labor increases the risk for a cesarean, especially in first-time mothers with an unripe cervix (one that has not done much dilating and effacing yet).

In the study, they specifically looked at cesarean rates among induced mothers with an unripe cervix.  They found that cesarean rates were particularly high among first-time mothers who were induced with an unripe cervix, but the risk was also elevated for mothers with prior vaginal births who were induced on an unripe cervix.  

This is why it is absolutely vital to ask your provider about your Bishop Score before agreeing to induce labor.

The Bishop Score

The Bishop Score is a measure of how soft and ripe your cervix is before labor. It can help predict whether or not your body is ready for labor, and whether or not an induction is likely to succeed or fail.

A vaginal exam is done and the care provider evaluates the degree of:
  • cervical dilation (how far the cervix has opened so far)
  • cervical effacement (how thinned out the cervical walls are)
  • cervical consistency (how soft or firm the cervix is)
  • cervical position (whether the cervix is pointing forwards or backwards relative to the vaginal walls)
  • fetal station (how far down the baby is in the pelvis)
[If you need further explanation about the terminology above, you can find an excellent explanation and great illustrations here.]


Each factor is "graded" on a scale of 0-2 or 0-3.  The maximum possible score is 13. This all adds up to what some doulas call "induction math".

The exact cut-offs used differs by source, but generally a score of 5 or less indicates the woman is unlikely to go into labor spontaneously at that time, and that an induction is likely to fail (result in a cesarean).

A score of 8 or more indicates that an induction is more likely to succeed.  A score of 9 or more indicates the woman will likely go into labor on her own very soon.

Sometimes care providers use modifications of a Bishop Score to help predict likelihood of successful induction.  One point may be added to the score for the existence of pre-eclampsia or for every previous vaginal birth.  One point is often subtracted for a "postdates" pregnancy, being a first-time mother (or for no previous vaginal births), or preterm prelabor rupture of membranes.

The Bishop Score is just one tool for predicting a woman's response to induction.  Obviously, other factors matter as well.

The Influence of Fetal Position

One often-overlooked factor is fetal position ─ which way a head-down baby is facing in utero.  Most babies face either occiput anterior (back of the head towards mother's belly; baby looking at mother's back) or occiput posterior (back of the head towards mother's back; baby looking at mother's belly).

Often a low Bishop Score is associated with a posterior baby, which is a less ideal position for birth.  In this position, the the baby's head is not putting pressure as efficiently on the cervix, so there is less cervical effacement or dilation, and the cervix is often posterior (pointed towards the lower vaginal wall and hard to reach during a vaginal exam).  When the baby rotates to anterior, the Bishop Score often changes dramatically because the physics of the baby's pressure changes.

Many "overdue" babies are actually posterior babies whose positions are simply not putting the most efficient kind of pressure on the cervix to thin and dilate, and so the body wisely does not go into labor yet.  Forcing the issue by inducing labor when the baby is posterior (or has other malpositions) tends to result in long, hard labors that often end in a c-section.

[This is a pet peeve for me, because it is the story of my first c-section....induced at 40 weeks despite a very low Bishop Score (the OB told me I had a "horrible" cervix) and a malpositioned baby.  Small wonder I ended up with a cesarean!]

So if your Bishop Score is low, it may not just be that your body is not "ripe" for labor, it may also be that the reason you are not ripe is because the baby is not in a great position for labor.  For that reason, it may be wise to delay inducing until the baby is in a more favorable position for labor.

Seeing a pregnancy chiropractor and getting adjusted may help encourage the baby to get into a better position for labor, which in turn might lessen your chances for a cesarean.  (This is what was key for me in my VBACs.)

Induction Triples the Risk for Cesarean in First-Time Mothers

In the 2011 study listed below, the charts of women who were induced with a Bishop score of less than 7 were studied.

Those first-time moms who were induced with a Bishop score less than 7 had a whopping 42% cesarean rate.  

This shows just how important it is to have a nice ripe cervix before inducing labor, and especially so in first-time moms, whose cervices have never dilated before.

Sometimes a doctor will try to reassure you that it doesn't matter if your cervix isn't ripe; they use drugs that help ripen the cervix before starting the induction drugs.  And it's true that these drugs can help at times.

However, even with cervical ripening methods, many inductions still fail.  Cervical ripening drugs are simply not a panacea for preparing the body for birth when it's not ready.  They work best when the baby is in good position and the body is close to being ready but not quite there yet.  Cervical ripening methods are very unlikely to help in women with very low Bishop Scores.

Now, if the cervix has dilated before, induction is more likely to work. Women who had had vaginal births before had a much lower cesarean rate after induction in this study, 14%.  Still, this was nearly double the cesarean rate of those multips who went into labor spontaneously.  

Obviously, cervical ripeness matters, even in women who have had vaginal births before.

Take-Home Points About Induction

Additional research confirms that cervical ripeness is one of the key factors in whether or not an induction will work.  Here are some take-home lessons from the 2011 study:
  • Whenever possible, wait to go into labor spontaneously
  • If induction is being considered, try to avoid inducing if your Bishop Score is less than 7
Other general bits of wisdom about inductions:
  • Try to see a provider who is not induction-happy and won't induce automatically at a certain gestation.  This is especially important for women of size, because many providers induce "obese" women at extremely high rates (a 50-60% induction rate is common in many recent studies).  This is a direct but under-acknowledged factor in the very high cesarean rate in women of size.
  • Question whether an induction is truly necessary in your case.  Many inductions are done routinely, simply because it is convenient for the provider or protocol to induce by a certain gestational age.  However, you don't have to agree to this intervention.  Discuss the pros and cons of the induction vs. waiting with the provider, and see if you can negotiate for more time.  
  • If you are contemplating an induction, ask about your Bishop Score before agreeing to the induction.  If at all possible, try not to induce before you have a favorable Bishop Score. 
  • If you are contemplating induction, ask about your baby's position before agreeing to the induction.   If the baby is not anterior, consider delaying the induction.  Seeing a well-trained pregnancy chiropractor may help encourage the baby to get into an easier position for birth.
  • If a medical condition makes induction necessary even with an unripe cervix, look into ways to increase cervical ripeness before the induction.  This can include acupuncture, herbs, and cervical ripening agents.  Consider the pros and cons of each choice carefully for your situation, and remember that gentler methods generally need a longer time to be effective.  Don't wait to the last minute to try the more gentle methods of cervical ripening if you are very likely to face induction.
  • Be sure your provider allows adequate induction time before resorting to a cesarean.  Recent research has shown that many providers move to a cesarean too soon in an induction; allowing just a few more hours (provided mother and baby are doing well ) may result in a vaginal birth after all.
  • Remember, induction doesn't automatically mean you're going to have a cesarean; many women who are induced do end up having a vaginal birth.  Go in with a positive attitude, try to remain as mobile as possible, and be sure to have professional labor support (a doula), who can often help maximize your chances even during an induction.  However, because an induction does increase the chances for cesarean, be prepared for any possibility and have a cesarean birth plan ready if one becomes necessary.
Induction is more and more common these days.  This is why it is important for all women to be informed birth consumers and learn more about their choices around induction.  The Bishop Score is an important ─ and often overlooked ─ part of this discussion.

OBJECTIVE: To assess the risk for emergency cesarean section among women in whom labor was induced in gestational week ≥41 and to evaluate if parity and mode of induction affected this association.
DESIGN: Hospital-based retrospective cohort study.
POPULATION: Singleton pregnancies delivered after ≥41 gestational weeks at Danderyd Hospital, Stockholm, Sweden, during 2002-2006.
MATERIAL AND METHODS: Of 23 030 singleton pregnancies meeting the entry criteria, 881 were induced with a Bishop score of less than 7. Obstetric outcome was assessed through linkage with the Swedish Medical Birth Registry and a local obstetrical database containing information from patients' medical files. Results were adjusted for body mass index, age and the use of epidural analgesia.
MAIN OUTCOME MEASURE: Risk for emergency cesarean section.
RESULTS: Among women who were induced, the proportions delivered by emergency cesarean section were 42% for nulliparous and 14% for multiparous. Compared to spontaneous onset, this corresponded to a more than threefold increase in risk for nulliparous women (OR 3.34, 95% CI 2.77-4.04) and an almost twofold increase in risk for multiparous women (OR 1.94, 95% CI 1.24-3.02). There was no significant difference in risk for emergency cesarean section between the two methods of induction (PGE(2) and transcervical catheter).
CONCLUSIONS: Compared to spontaneous onset of delivery, induction of labor is associated with an increased risk for emergency cesarean section both among nulliparous and multiparous women. When labor is induced, the high risk for emergency cesarean must be kept in mind.

The rate of labor induction is increasing in the United States. Methods for quantifying cervical factors have been developed to identify patients who may benefit from cervical ripening before induction. The first cervical scoring systems used digital examination. More recently, cervical ultrasound and testing for the presence of fetal fibronectin have been suggested to evaluatecervical readiness for labor induction, but neither of these methods provides a significant improvement over digital examination. The Bishop score, the most widely used digital examination scoring system, still is the most cost effective and accurate method of evaluating the cervix before labor induction.

OBJECTIVE: To quantify the risk and risk factors for cesarean delivery associated with medical and elective induction of labor in nulliparous women.
METHODS: A prospective cohort study was performed in nulliparous women at term with vertex singleton gestations who hadlabor induced at 2 obstetrical centers. Medical and elective indications and Bishop scores were recorded before labor induction. Obstetric and neonatal data were analyzed and compared with the results in women with a spontaneous onset of labor. Data were analyzed using univariate and multivariable regression modeling.
RESULTS: A total of 1,389 women were included in the study. The cesarean delivery rate was 12.0% in women with a spontaneous onset of labor (n = 765), 23.4% in women undergoing labor induction for medical reasons (n = 435) (unadjusted odds ratio [OR] 2.24; 95% confidence interval [CI] 1.64-3.06), and 23.8% in women whose labor was electively induced (n = 189) (unadjusted OR 2.29; 95% CI 1.53-3.41). However, after adjusting for the Bishop score at admission, no significant differences in cesarean delivery rates were found among the 3 groups. A Bishop score of 5 or less was a predominant risk factor for a cesarean delivery in all 3 groups (adjusted OR 2.32; 95% CI 1.66-3.25). Other variables with significantly increased risk for cesarean delivery included maternal age of 30 years or older, body mass index of 31 or higher, use of epidural analgesia during the first stage oflabor, and birth weight of 3,500 g or higher. In both induction groups, more newborns required neonatal care, more mothers needed a blood transfusion, and the maternal hospital stay was longer.
CONCLUSION: Compared with spontaneous onset of labor, medical and elective induction of labor in nulliparous women at term with a single fetus in cephalic presentation is associated with an increased risk of cesarean delivery, predominantly related to an unfavorable Bishop score at admission.
