Nulliparous psychosocial induction
I have been reading about induction recently, specifically, nulliparous induction for psychosocial reasons with an unfavorable cervix. In English, that is a first time mom, getting a labor induction for non medical reasons, and her cervix is not dilated or softened.
Induction of labor is relatively common. I recently sat with a doula client during her induction with Cervidil (Dinoprostone). (Not a comfortable placement procedure when you have a posterior, undilated cervix. It seemed more painful than any contraction I have ever seen.) Before it was applied, she was chatting with the nurse, who was 38 weeks pregnant. The nurse was happily anticipating her own induction, saying “I want to get her out before she’s too big.”
I briefly mentioned that estimations of fetal weight were not evidence supported and notoriously imprecise. I didn’t feel it was appropriate to mention that, at least according to the textbook we used for our women’s health system, induction was not recommended for suspected macrosomia. In fact, I had to point that out, politely, after class, to our pharmacology professor. She would read from the lecture notes, then pepper the lecture with the story of her own delivery, which was a failed induction for suspected macrosomia. She had a cesarean for fetal distress. The way she told the story, that was a good treatment decision, and suspected macrosomia was an indication for induction. I showed her the section in our textbook, said I thought it seemed contradictory, and suggested she talk about it with the head of the department.
I knew induction + macrosomia has an association with shoulder dystocia. Well, I was trying to find out more information about induction and Bishop score. Although this particular doula client met the ACOG recommendation of reaching 39 weeks gestational age, I was fairly sure a favorable Bishop’s score was more important. I had told this to my doula client when she mentioned the 39 week induction. I understood why she wanted it. She was on strictly limited maternity leave. Her mother was flying in. Anyone who has been pregnant full term or has talked with women who are in their late third trimester knows they are usually extremely uncomfortable and sick of being pregnant. She was no different.
Also, her obstetrician had already predicted, several weeks before, that she would go into labor a full ten days before her due date. Yes, it was the nature of her job that she was on her feet a lot, but who says that to a nulliparous woman with a long, closed, posterior cervix? I certainly don’t mean to imply she was setting the stage for a 39 week induction that she could work around her clinical schedule, but talk of induction started to happen as soon as that ten-days-before-due-date due date passed. I mentioned the Bishop’s score, and she seemed to think her obstetrician thought her cervix was ready. But, when we got to the hospital for the induction, her cervix was closed and posterior. I didn’t hear an exact effacement, but even with a generous guess, there is no way she was above a Bishop score of 8. I don’t think her doctor told her that it meant she had twice the risk of a cesarean. I didn’t think it was appropriate to tell her, since they didn’t do the cervical exam until the Cervidil was ordered and unwrapped, and she was admitted for the induction that she and her physician had decided was right for her at her last prenatal visit, and the physician was managing the induction over the phone.
Well, when researching the decision making that goes into these common inductions, I have read some interesting things. The first was on the Cervidil site I linked to above, that lists “Patients in whom there is evidence or strong suspicion of marked cephalopelvic disproportion” as a contraindication for Cervadil. In other words, suspected macrosomia.
Secondly, on the ACOG website, a recent article about quality improvement by Dr. D. Ware Branch, Jr., says:
“[B]eginning nearly 10 years ago, the program sought to implement a systematic, multi-institutional approach to discourage elective inductions in nulliparous women with a Bishop score of less than 10.
During the first several years of the project, the number of elective inductions in nulliparous women with an unfavorable cervix decreased from approximately 105 per month (15%) to 60 per month (6.7%) in the 11 hospitals that participated. The total number of elective inductions in nulliparous women also declined by two-thirds.
Currently, the proportion of nulliparous women with an unfavorable cervix undergoing elective induction within the Intermountain Healthcare system is less than 5%. Some facilities have even disallowed any nulliparous inductions whatsoever.”
Also, when rereading ACOG’s Practice Bulletin on Induction, (which is problematic for a few reasons) I noticed it states “Although trained nursing personnel can monitor labor induction, a physician capable of performing a cesarean delivery should be readily available.” Hmm, that sounds remarkably similar to the recommendation in their Practice Bulletin on Vaginal Birth After Cesarean, which states “VBAC should be attempted in institutions equipped to respond to emergencies with physicians immediately available to provide emergency care.”
I am not trying to say that elective inductions should never be done, not even that they should never be done for psychosocial reasons. However, I doubt many nulliparous patients are given a risk explanation for an elective induction that is in anyway similar to the common treatment of VBAC. I am also fairly sure that elective inductions in nulliparous women for psychosocial reasons will not be banned from many facilities, like VBAC currently is. As far as I could tell by this interaction between my client and her nurse, elective induction for nulliparous women seems pretty standard, at least in my area. The quality improvement article from the ACOG website was reassuring, however.
The ultimate KALI questionnaire
This is the absolute last version of the KALI questionnaire. (You can access the previous incarnations here.)
How do I know this? Well, first of all, one of my mentors gave me the lifted eyebrow when I went to him to talk about the wording, again, on Monday. I am particular and a hair splitter, but I also had a good reason to change the wording of this part. I had a problem with it from the beginning, and one of my beta testers also had an issue with it. I was editing the second to last question, and it used to say “How often do you consult the following sources regarding obstetrical practice?” But, I really didn’t want to know how often the physicians literally consulted these sources. No physician furtively looks in a textbook “always” or “often”. I wanted to know how useful these sources were in clinical decision making, how valuable the physicians considered each source to be, and how often they applied the knowledge from these sources to their clinical practice. And, I wanted it to be in one question, since I had three complaints about the length of the survey by beta testers. (This version is also a few questions shorter, and one question is a combination of two previous ones.)
So, I ended up with: “This final section lists potential sources that you may consult to stay up to date on obstetrical standards of care. How often are the following sources useful in making clinical decisions?” Not perfect, but I am accepting it and moving on.
The second reason I know this is the final version, at least for this research, is because I sent out a few email invites yesterday. (Eep! Wish me a good response rate!) I will be phoning ob/gyn offices today, begging for email addresses for the physicians in the practice. (Eep! Wish me good luck getting email addresses!)
So, here is the final questionnaire:

Mammograms and the USPSTF: it’s the denominator, stupid
There has been a lot of brouhaha over the new mammography recommendations by the United States Preventative Services Task Force (USPSTF). Rachel at Women’s Health News has an excellent round up of posts on the issue, if you feel like you need to do some background reading.
I am also a big fan of Barbara Ehrenreich’s take on it.
Take your time if you need to check out those links, since I highly recommend it. Back? Good.
I have many thoughts on this issue. First of all, I am completely in support of the new recommendations. If you have been reading my blog for long, this may come as no surprise, since I tend to prefer using interventions only when absolutely necessary, and am a big fan of evidence based medicine.
Secondly, I don’t think it is anti-feminist to discuss the anxiety caused by false positive diagnoses, whether it be false positive mammography results or false positive prenatal genetic screening results. Not only is the anxiety potentially substantial to many, but, the false positives also lead to more invasive tests. My mother, who is as low risk as I am for breast cancer (white, has had children and has breastfed, non-smoker, not a heavy drinker, no first degree relatives who have had breast cancer, etc.) is also endowed with huge breasts, as I am. She had at least three biopsies and lots of ultrasounds in her 40’s. None of these came up with anything of concern, but there was plenty of anxiety leading into them. And, a biopsy is not comfortable or risk free. Come to think of it, neither is a mammogram. In fact, the radiation from repeated mammograms may actually cause breast cancer in some women. I know this is an anecdotal story, but my mother is the primo example of who this consensus opinion is talking about. These mammograms are not improving outcomes in typical low risk women in their 40’s, like my mom was when she started getting mammograms and subsequent biopsies.
Third, I had an argument with a fellow student today. He said that the public wants the extra mammograms, and they are too stupid to understand the nuance to the issue. He also said all they want is “the best care.” I said the best care is evidence based care, and that I plan on educating my patients. I do not believe in the can-I-have-fries-with-that-have-it-your-way approach to medicine. I do believe that patients’ values and opinions definitely matter. But, in the end, if a patient insists on a procedure I think will cause more harm than good, I will politely refuse and refer them to a practitioner that will accommodate them, if I know of one.
Fourth, and possibly coolest, I heard a discussion on Doctor Radio that made my nerdy day. The oncologist, Dr. Silvia Formenti, is fully supportive of the new recommendations. She also explained why there is an apparent discrepancy in breast cancer survival rates between the United States and United Kingdom, which is one of the few if only outcomes that appear better in the United States. She explained that this is a false comparison, since the denominator is different. My public health instructor has always harped about the denominator of any rate being key, but I thought it was just a nitpicky instructor thing – sure, you only include women of childbearing age in maternity rate stats, got it – but it’s more important than that. Dr. Formenti said that the reason our rates seem better is that we are currently overscreening younger women, and overtreating in situ cancers. So, our denominator is stacked with low risk women who are not really that sick. In fact, I spent too much time looking over the ACOG site for the article, but I read something recently in one of their publications that showed that a wait-and-see protocol for such cancers led to a shocking remission rate. I remember it being over 20%, but since I cannot find the article, please don’t quote me on it.
So, the denominator matters, and not just in a nit-picky way. Also, I was happy to see that the National Health Service, of which I am a fan, is not failing women with breast cancer, which was bugging me a little. What especially impressed me with her commentary was that not only is she a renowned oncologist and an attending at NYU Langone, but she practices in the United States. She could have easily said “Hooray for my team, hooray for my field, we’re kicking butt.” It’s really refreshing to hear someone value truth over seeming to be the best.
And, finally, I am a little chagrined by how many people are saying that these USPSTF recommendations are going to change the way the insurance companies reimburse mammography, and change medicine in the United States dramatically. I am still waiting for that to happen due to their recommendations of labor and delivery from November of 2008, in which many interventions are panned as inconclusively supported by evidence or detrimental to patients (such as third trimester estimation of fetal weight, denying nutrition p.o. to laboring patients, and episiotomy) and others are highlighted as extremely effective and highly recommended (e.g. upright positioning for pushing and the continuous support of a doula during labor.) I wish there was an uproar following those dramatic recommendations, but there was barely a peep. Hello, sweeping changes? Helloooooooo?
Moving during labor
Amy at Lamaze’s Science and Sensibility is hosting the second Healthy Birth Blog Carnival. This one is about Lamaze’s Second Healthy Birth Practice: Walk, move around, and change positions throughout labor.
Amy did a great job explaining how natural birth advocates are constantly asked to prove that what is physiologically normal, like being free to move during labor, is better than an intervention, when it should be the other way around. Here’s a great quote from her anticipatory pre-carnival post:
Somehow, things have gotten turned around, and the normal condition is now the “experiment” and the intervention is the “control”. In addition to being irrational, this is a set-up to perpetuate conventional obstetric care, which imposes unhealthy and unfounded restrictions on women in labor. This is because in “intervention versus control” research, you have to show that the intervention performs significantly better, otherwise the control condition remains standard practice. While many of us believe that encouraging a laboring woman to move when and how she wants to is healthier and safer than making her stay in bed, waiting for evidence that it produces better health outcomes is putting a burden of proof on normal birth that has never been applied to routine intervention. Besides, lack of evidence of harm, less pain, and maternal satisfaction are valid and important outcomes in and of themselves, and provide the justification we need to reject routine policies and practices that restrict maternal movement.
I had a similar argument with a commenter on this post. Many elective cesarean advocates seem to want to present vaginal birth and cesarean birth as two equal options, not a physiologically normal event and an intervention.
So, since Amy already handled this angle well, I am going to talk about my own experience, and give a little advice at the end.
When I had my first child, I thought I was well informed. Hell, I had read every page in What to Expect When You’re Expecting. I read Mothering and Parenting magazines (both sides!), hired a midwife, took a childbirthing class, and thought I would have a “natural birth” as long as there wasn’t any unexpected emergencies.
Well, soon after I arrived at the hospital, I was told they didn’t have a birthing tub (I never thought to ask ahead of time, dangit) but I was told I could labor in the shower. After the shower, which was probably 20 minutes at the most, I was told I needed an IV with Pitocin. I had no idea what that was, but since my midwife recommended it, and everyone knows midwives always favor natural births over interventions, I didn’t even think of refusing. Well, I was told as soon as the Pitocin was started that I needed to be on continuous external fetal monitoring. Huh? Then, my midwife told me I had to stay in my bed(!!!), since the baby was showing signs of distress. I was not told before being administered the Pitocin that it would require being tethered to the machine, and I wasn’t told it may cause fetal distress, even after my fetus was apparently diagnosed with fetal distress. I wasn’t even told it may not be necessary, considering I had only been in active labor for about an hour when it was administered.
Fast forward several hours and I was flat on my back, pushing too soon, leading to a swollen cervix. No, no alternate positions were encouraged for my three hours of pushing, either.
So, my advice? Ask your practitioner(s), ahead of time, what their positions are on intermittent monitoring and movement in labor. Don’t just assume that what seems basic and normal will be encouraged or allowed.
More on fat bias and pregnancy
Jill at The Unnecessarean linked to this frustrating but great birth story at My Best Birth. “A Curvy Gal’s fight for a Natural Childbirth” is full of head exploding details, such as baseless threats from her midwife, recommendations for risky procedures with a lack of adequate informed consent, and suggestions of medical approaches that would actually increase the risk of adverse outcomes, not decrease them.
Here is a choice quote:
After some research, I called my midwife to say that I did not want a Miso induction, and that I wanted to wait and go into labor spontaneously. She said, “Well, in my experience, women with BMIs higher that 26 tend to have cervixes that won’t dilate without chemical induction.” Okay—first I was being pressured into induction because of the increased risks of a long gestation to m y baby and NOW she’s saying that because I am a curvier gal, my body is somehow clueless about giving birth (by the way, I had NO other risk factors in this pregnancy—no gestational diabetes, no elevated blood pressure, etc) I have since searched high and low for ANY medical study that supports her belief and have come up with nothing. I argued with her that I’d like to give my body the chance to go into labor on its own—at least through the weekend (agreeing to the postponed induction with the foly (sic) catheter instead). She was condescending and doubtful, but ultimately said it was up to me.
Rrrrrrgh.
The good news is that she did her research, refused the inductions, and ended up going into labor spontaneously and having a quick and easy birth.
Sick and leaning on the mute button
So, I am sick. Sick sick sick sick. I hurt everywhere. I have a fever and I am lightheaded. Runny nose, cough…the works. Blegh.
I am planted in front of the computer and the TV. I watched these Bill Nye videos about genetically modified foods. I just happened to get a link for them by being a fan of Slow Food USA on Facebook. It was interesting timing (not ironic, huh CableGirl?), since I just got in an annoying argument with commenters on on Dispatches from the Culture Wars. First of all, I am no fan of people who use snotty insults when they’re arguing on a site. Not necessary. Sarcasm is fine. But, if you’re going to go there, you better be right. I also don’t think blindly accepting technological advances is any more reasonable or educated than being blanketly afraid of all technology.
So, while I was tooling around on the internet, I had the Travel Channel on mute. Anthony Bourdain was visiting Ted Nugent. I could never listen to that much douchebaggy conversation, but I left it on in case there were any exciting gun accidents. Not that I wish that on anyone, but still, it’s exciting.
Now I am watching Birth Day. I wish I had the mute on here, too. I have heard “vertex position is NECESSARY” for a vaginal delivery. Also, I heard about a woman who had been in a long labor, and when her nurse introduced the next shift nurse, she said “And Amy has been with us forever.” Nice. She ended up with a fever after several hours of an epidural, and of course they discussed ZOMG infected baby!! but didn’t mention the link between epidurals an fever. The baby was born by “abdominal rescue” (wha??) and then was immediately taken to the well child nursery. Wait, I guess they don’t think there is a big risk this baby is infected. Then they talked about how it’s just great that she had a healthy baby.
I did get to see a successful external version (I cheered!) but I was surprised to see she got a neck down epidural for it, and then they induced labor immediately. I don’t know that much about external versions, however. The baby has distress now. They think it’s from the version. But, can it be from the Pit?
There is a woman who is one day past her due date (the horror) and was told her baby is “big” and she needs a cesarean. Oh, but she’s a hemophiliac. How does this sound safer? Her bleeding time test did not look good from my amateur eye. Why cut her without good indications?
