The Choosing Wisely campaign was begun in order to reduce unnecessary use of medicine and medical procedures.  Non-medically indicated use is unsafe for patients as well as being expensive.  Not only are there costs involved in the medicine or procedure itself, but there are also costs in treating side effects and other health consequences.

The American College of Obstetricians and Gynecologists (ACOG) has a list they made for the Choosing Wisely campaign, “Five Things Physicians and Patients Should Question.”  The top two items on the list are about elective induction of labor (these two items also made the American Academy of Family Physicians list).  The first warns against scheduling a delivery (cesarean or induction) before 39 weeks unless there is a clear medical indication.  Here is the text of the second:

Don’t schedule elective, non-medically indicated inductions of labor between 39 weeks 0 days and 41 weeks 0 days unless the cervix is deemed favorable:  Ideally, labor should start on its own initiative whenever possible. Higher Cesarean delivery rates result from inductions of labor when the cervix is unfavorable. Health care practitioners should discuss the risks and benefits with their patients before considering inductions of labor without medical indications.

This is similar to the information I provided in my posts on Pitocin and elective inductions.  Before 41 weeks, unless there is a clear medical indication, labor should begin on its own.  Note the caveat that if an elective induction is to occur, the cervix should be “favorable.”  A laywoman might ask what this means.  A favorable cervix is soft, effaced and dilated.  But really the standard that physicians use for determining whether a woman’s body is ready to labor is the Bishop score.

In 1955, Dr. Edward Bishop published a paper (subscription needed to get text) on elective induction of labor in which he looked at the likelihood of induction success based on several factors: fetal position, cervical softness, cervical effacement, cervical dilation, and the “station” of the fetus (how far it was engaged in the woman’s pelvis).  We might question the ethics of inducing labor without medical indication, but Dr. Bishop did find that if the baby was anterior and the cervix was soft,  higher levels of effacement, dilation and engagement made elective inductions likely to work and labors were more likely to be shorter.  This chart from Preparing for Birth sums it up:

Bishop’s scoring system is still used and has some accuracy at predicting the likelihood of an induction’s success.  Some doctors use a simplified score that just looks at effacement, dilation, and station.

Here are some graphs from Intermountain Healthcare’s care process model on elective induction:

You can see that higher Bishop scores lead to higher likelihood of a successful induction, and that the higher the score, the shorter the labor.

Nulliparous women (first time mothers) are especially likely to have cesareans when they have lower Bishop scores.  It is important to note, however, that even with a favorable Bishop score, nulliparous women are much more likely to have a cesarean than they would be if labor began on its own, and they are more likely to have operative deliveries (forceps or vacuum).

Dr. Gene Declercq of Boston University and colleagues run a wonderful site call Birth by the Numbers and produced this chart with data from Listening to Mothers III:

This data does not imply that an induction cannot be successful, that no one should have an epidural, or that a cesarean might not be necessary for reasons having nothing to do with inductions or epidurals.  But the data do give credence to the idea of choosing wisely.  Taking Pitocin to start labor in an uncomplicated pregnancy before 41 weeks is akin to taking high blood pressure medicine when your blood pressure is normal (credit Debra Bingham).  The Bishop score may help to determine if the medicine will not hurt you, but why take it in the first place?  If you do want to go the induction route, however, your Bishop score is a tool to let you know how likely an elective induction is to lead to unnecessary major surgery.

All inductions should be done with full informed consent and should not be scheduled around a care provider’s office hours, vacation time, or child’s birthday party.  The well being of the pregnant woman and her fetus and the woman’s informed choice should be the only considerations.  A woman is a human being and not a vessel to be manipulated for the convenience of others.

When something goes wrong, we often seek someone to blame.  Sometime the culprit is obvious, as when someone hits you or rams into your car or knocks over your vase.  When things go wrong in a pregnancy, it can be harder to tell what happened.  But having someone to blame is comforting.  Assigning blame allows us to believe that avoiding the blameworthy person’s mistakes will spare us a similarly bad outcome.

Blaming Mothers

People are quick to blame women for any bad pregnancy outcome–miscarriage, preterm birth, still birth, baby with disabilities, baby with genetic disorders, low birthweight baby and on and on and on.  Any choice a pregnant or birthing mother makes, it seems, can be used against her.  A New York Times piece points out that

much of the language surrounding advice to pregnant women as well as warnings is “magical thinking” that suggests that women who do everything right will have healthy babies — and therefore, women who have babies with birth defects failed to do everything right.

Women are blamed for not following a doctor’s orders, even if those orders have no basis in evidence, such as bed rest to prevent preterm birth.

Women may be blamed for not following folk wisdom: some people strongly believe that a pregnant will miscarry if she lifts anything heavier than a frying pan or that her fetus will strangle on its umbilical cord if she raises her arms over her head.

Women may be blamed if they do follow a doctor’s orders if a bad outcome occurs.  Virginia Rutter notes the following case from Paltrow and Flavin’s 2013 article on the criminalization of pregnant women:

A Louisiana woman was charged with murder and spent approximately a year in jail before her counsel was able to show that what was deemed a murder of a fetus or newborn was actually a miscarriage that resulted from medication given to her by a health care provider.

Women may be blamed for choosing a provider or place of birth someone else feels is inadequate.  One mother who planned to birth at home with a registered midwife wrote,

If something does go wrong, with the birth, or otherwise, [my mother] is going to blame me forever, for my “selfishness.” If the baby grows up to have a learning disability or something (for whatever reason), my Mom [who had cesareans] is going to say that it’s all my fault for having a natural birth, that I damaged the baby’s brain.

In fact, blame may be heaped on women for things that others believe have the potential to cause poor pregnancy outcomes, even if the actual outcomes are just fine.  For instance, women are often pilloried for having so much as a sip of wine during pregnancy, even though the evidence of harm in to the human fetus from low to moderate alcohol use is nearly nonexistent.

Women may even be blamed for things that they no longer do, as was the case with Alicia Beltran, who was imprisoned for refusing medical drug treatment while pregnant because she no longer used drugs.

Blaming Providers 

Some OBs openly acknowledge that their colleagues find it difficult to change practice in response to new scientific information–or even old scientific information.  Some examples are recommending bed rest, performing routine episiotomies, and using Pitocin for elective induction of labor.  However, when a woman or her infant develops a complication from one of these routinely prescribed interventions, the physician is rarely blamed for the poor outcome.  In fact, the doctors are often lauded in such circumstances for doing “all they could.”

Doctors  claim that women demand potentially harmful procedures, such as elective inductions or cesareans. Ashley Roman, MD, a maternal fetal medicine specialist at NYU Medical Center said,  “I have definitely seen an increase in C-section requests, even when there is no real medical justification behind it.” But the Listening to Mothers III survey found, “Despite much media and professional attention to ‘maternal request’ cesareans, only 1% of respondents who had a planned initial, or ‘primary,’ cesarean did so with the understanding that there was no medical reason.”

ACOG actually sanctions elective cesareans (albeit reluctantly).  In a 2013 Committee Opinion on elective surgery, ACOG concludes, “Depending on the context, acceding to a request for a surgical option that is not traditionally recommended can be ethical.”  Though their 2013 Committee Opinion on maternal request cesarean says vaginal birth should be recommended, it provides parameters for performing an elective cesarean.

Doctors sometime behave as if they are helpless to say no in the face of maternal request for elective medical procedures, such as cesareans or early inductions.  The director of women’s services at one hospital with a high early induction rate said,

A lot of the problem was the fear among our physicians that if they didn’t do what the patient asked, they’d go find another doctor. It was a financial issue.

Women, however, report that physicians consistently offer elective inductions and cesareans.  On the Evidence Based Birth Facebook page, Megan posted, “I was ‘offered’ an induction at 39 weeks at every visit starting at 34 weeks.”  At The Bump, user Ilovemarfa wrote, “I was induced with my son when I went overdue by over a week and he was estimated to be about 10 lbs 5 oz. My doctor offered me a c section due I possible high birthweight…” Her baby weighed 8lbs 9 oz.  Note that a prophylactic cesarean is only supposed to be considered if the baby is estimated to weigh at least 11 pounds.

Physicians may act as if they are doing women a favor by offering elective procedures.  For instance Emily on Baby Gaga posted,

I’m due [in two weeks]. I went to the doctor today. Last week I wasn’t dilated, but now I am 3 cm. He said if I don’t have the baby by my next appointment, I could pick a day, and they would induce me. No medical reason.

Or the provider may state that the procedure will be done, without any discussion or informed consent process.  On the Evidence Based Birth Facebook page, Becca reported, “[My]care provider did routine 36 week ultrasounds. [I] was told I was going to have a ‘Texas sized baby’ and would be induced if labor didn’t start…before 40wks.”   Dana was told at 29 weeks that “All first time moms need an episiotomy.”

In their Committee Opinion on Maternal Decision making, ACOG recommends,

Pregnant women’s autonomous decisions should be respected. Concerns about the impact of maternal decisions on fetal well-being should be discussed in the context of medical evidence and understood within the context of each woman’s broad social network, cultural beliefs, and values. In the absence of extraordinary circumstances, circumstances that, in fact, the Committee on Ethics cannot currently imagine, judicial authority should not be used to implement treatment regimens aimed at protecting the fetus, for such actions violate the pregnant woman’s autonomy.

Despite their acceptance of elective interventions and a professional ethics opinion stating that women’s decisions should be respected, physicians sometimes threaten or persecute women when they refuse interventions–whether they are evidence based or not.  At the blood-pressure-raising website My Ob Said What?, a woman who told her OB that she refused to schedule a routine C section for her twin pregnancy (not evidence based) reported that she was told,

If you do that, then we’ll have to get social services involved and believe me, you don’t want that, Cookie.”

Another said she was told,

If you don’t agree to the cesarean section, we will call Child Protective Services and they will take the baby away for someone to be a real parent.”

A woman in Florida “was ordered to stay in bed at Tallahassee Memorial Hospital and to undergo ‘any and all medical treatments’ her doctor, acting in the interests of the fetus, decided were necessary.”  She was not even allowed to ask for a second opinion (bed rest is not evidence based).

One woman pointed out that doctors are not “reported to social services for child endangerment every time they try to induce a baby who’s not ready to be born, just for their own convenience” but that “if a mother did something for her own convenience that landed her child in the hospital, there sure as hell would be…lots of tough questions, lots of shaming.”

As stated earlier, when bad outcomes happen because of a physician’s choices, people often praise the doctor’s heroic efforts, even if the dangerous situation was caused by the physician.

A prime example is use of Pitocin without medical indication (you can read more about Pitocin here and elective induction here).  Some doctors who want to rush a birth or generate a reason to perform a cesarean practice something called “Pit to distress.”  Nursing Birth has an in-depth explanation with examples, but the short version is as follows:

  • A doctor starts Pitocin to induce labor or augment it (speed it up).
  • The dose is raised until the woman is contracting strongly and regularly.
  • The doctor orders that the dose keep going up, even though the woman’s contractions are already strong (at least 3 in 10 minutes).
  • The uterus becomes “tachysystole,” meaning there are more than 5 contractions in 10 minutes.
  • In many cases, not enough oxygen gets to the fetus under these conditions, the fetus goes into distress, and the mother is rushed to the operating room for an emergency cesarean that “saves” her baby.

Many times, the woman has no idea that the physician ordered that her Pitocin dose be raised, so she doesn’t realize that the doctor caused the fetal distress.  All she knows is that the baby was in distress, and that her doctor saved the baby from a potentially terrible outcome.

Even when bad outcomes occur, lawsuits are not common.  Despite the hype around liability, it doesn’t seem to impact practice the way doctors say it does.  After tort reform passed in Texas, limiting physician liability, the cesarean rate continued to go up at more or less the same rate as the rest of the country.  As one obstetrical nurse said, though physicians and nurses fear lawsuits, “hospital staff are rarely criminally prosecuted for their actions or inactions.”

Blame, Fate and Social Control

Certainly there may be someone to blame when a pregnancy or birth has a bad outcome.  But there may not be.  Blaming a doctor is frightening–it encourages people to question someone they need to trust with their lives–and their babies’ lives.  Fate can be even scarier–no one controls fate.  And in looking someone to blame, it seems society is often more interested in the social control of pregnant women than in rooting out the real culprit.  There may be those who escape unscathed, but nobody wins in this blame game.

I have written previously about problems with Pitocin overuse (and about widespread overuse of other medical procedures in birth).  Now that the holidays are almost upon us, it seems wise to revisit the Pitocin issue.

Pitocin is a synthetic form of oxytocin, a natural hormone that promotes bonding and also causes cervical dilation and labor contractions.  Using Pitocin interferes with the body’s natural output of oxytocin, doesn’t effectively dilate the cervix, and prevents the body’s release of endorphins that naturally alleviate pain.  There are sometimes good reasons for inducing labor with Pitocin (for instance, if the baby must be born right away for health reasons).  In many cases, however, good reasons are not in the equation when the Pitocin comes out.

In 1990, fewer than 10% of women underwent labor induction.  Now, estimates indicate that up to 40% or more of labors may be induced.  As scheduled cesarean rates have also gone up dramatically in that same period (see this graph), we know that the proportion of women planning a vaginal birth who are induced has gone up even more.  If you doubt that large numbers of births are being scheduled, see this graph that shows that births are disproportionately on Tuesday-Friday, with an extraordinary dip on weekends.

Doctors like to indicate that elective inductions are primarily done at maternal request.  While some women definitely do request inductions, pregnant women cannot induce themselves with Pitocin.  Doctors seem to have no problem enforcing non-evidence-based practices that women don’t want, such as not eating in labor, but act as if they are helpless in the face of induction requests.

Some doctors also have selective memory when it comes to their own induction practices.  According to mothers, childbirth educators, and nurses, it is usually doctors who are encouraging inductions.  As one childbirth educator said,

[A]n increasing number [of women] are being encouraged by their physicians to have labor induced. Threats of “your baby is getting too big” or “your blood pressure is a bit high” or “going past your due date is dangerous” and seduction with “your baby is ready, let’s get on with it” are almost routine.

Even some doctors acknowledge that elective induction is often physician driven.  Dr. Vivien von Gruenigen writes,

Health care providers may request a patient to have an elective induction of labor and the “fee for service” model is a factor.  This routine is common for physicians in solo practice with needed time off call or impending vacation.  In addition, many physicians in group practice schedule elective inductions when they are on call for the purpose of financial gain.

Inductions are usually performed without true informed consent.  Pitocin is not FDA approved for elective induction of labor and carries a black box warning because it is a high alert medication (prone to errors in administration that lead to catastrophic consequences).  It appears that very few women are told that they are receiving a high alert medication that is being used “off label.”

One suggested consent form for elective induction includes the following for women to acknowledge:

  • An increased risk of the need for cesarean section (surgical abdominal birth)
  • I have also discussed the use of cervical “ripening agents” with my physician and I understand their separate risks of: a. Excessive stimulation of the uterus to the point that my fetus may become compromised and require emergency delivery, either vaginally or abdominally. b. I also understand that rarely the uterus may rupture under these circumstances, and cause death of my fetus and severe hemorrhage or death to myself.
  • An increased risk that instruments may be used to accomplish a vaginal delivery if necessary.
  • I also realize that if I have a cesarean birth, I am likely to require cesarean births for all of the children I may have in the future, and that each of these will incur the usual risks associated with cesarean section that I might have avoided had I had this birth vaginally.
  •  I acknowledge that there may be an increased risk for the need of blood transfusion, and I give my full consent to receive blood and blood products as necessary unless specifically stated here:

I have never met a lay woman who was aware of all of these risks, even if she had undergone an elective induction.

Marilyn Curl notes that elective deliveries spike before holidays–but that women do not always realize that the induction is elective:

Few doctors want to be pacing the halls on Thanksgiving or Christmas, waiting for a mother to deliver, so it’s not uncommon to see a surge of women with normal pregnancies being told that there might be an issue and that they should consider scheduling the delivery, coincidentally, right before a holiday.

Jill Arnold has a whole post about the pre-holiday induction phenomenon at The Unnecesarean.

Aside from  the health risks, there are many other disadvantages to a pre-holiday induction, namely that there are so many of them being done that the obstetric wards are likely to be overcrowded.  Robin Elise Weiss notes that

  • Trying to schedule an induction just before Christmas ensures a hugely busy and overworked staff because of everyone else doing the same thing.  I’ve personally seen women laboring in the halls or having very long wait for services like epidural anesthesia because of it.
  • When you have a baby in the week before Christmas (with lots of other women), you’ve also got a crowded postpartum floor.  This means longer waits for being seen by pediatricians, getting pain medicationss, etc.
  • Being in the hospital in a crowded induction season can mean that you have to share resources in the hospitals that are already spread thin, like the lactation consultant, breast pumps, birth certificate clerks, etc.

At a recent PCORI conference, consensus opinion was that elective induction of labor before 41 weeks was one of the most important issues facing perinatal care today.  As Deborah Bingham pointed out, we don’t give people with normal blood pressure medication for high blood pressure, because that would be dangerous; similarly, we should not be giving healthy pregnant women medication designed for rushing a birth in a medically dangerous situation.  And it certainly shouldn’t be done by tricking women into thinking an induction is necessary because of a big baby or other concern that is not an indication for induction.

Not even before Thanksgiving or Christmas.
