Actually, for the BMJ study, participation was a requirement for re-certification as a CPM (certified professional midwife). Only something like 3 or 4 individual MOTHERS (out of more than 5,000) declined to be part of the study.

That's one of the things that makes the BMJ study so spectacular. No study of physician attended birth could ever come close to having 100% participation of providers.

While it's true that the BMJ study was self-report, it was also prospective, and, as any good researcher will do, charts were randomly audited. (For those out there wondering what prospective means: each mom was registered towards the beginning of the pregnancy, making it impossible, or at least really really difficult, to hide bad outcomes at the end).

The real problem is that organized medicine (you know -- ACOG and AMA) are pointing to two very flawed studies that greatly exaggerate the risks. The Washington Study (Pang et al.) was retrospective and relied on birth certificate data of anyone giving birth at home at 34 weeks or later who had a midwife or doctor listed. (34 WEEKS???? No one delivering a 34 weeker at home should retain their license, IMO). And there's an Australian study that included high risk moms in extremely isolated parts of the country. Clearly these two studies do nothing to add to a sincere discussion of planned home birth in America.

For the record: I am a consumer living a state that has no licensure for CPMs, so women where I live wanting a home birth must either book with one of the 4 home birth CNMs in the whole state the nano-second see that + sign, or rely on an underground network of unlicensed providers. THAT'S the real problem -- failure of half of the United States to license CPMs while ACOG, the AMA and state doctor's groups and hospital associations pour literally millions of dollars into campaigns to stop consumers like me who need access to licensed home birth care. If ACOG really cared about home birth women and their babies, they'd stop making policies blocking access to collaborative care and stop blocking licensure laws for CPMs.

Had almost identical experience with my first-born. As I await the birth of my second, I'm looking for insight into this occurrence. How can I prevent a repeat? Any help appreciated.

15% is a good rate, you're doing good work. Rural hospitals - in part because of the lack of OBs hovering over and generally less anesthesia - do have lower rates.

Our birth center / homebirth practice (going strong for our 30th year now) has consistently a 5-6% c/section rate, most planned for known breech births. C/Sections are important and sometimes life saving. FYI this year we will have over 400 out of hospital births.

But the national average IS over 30% (32+ I believe at last count?) and that is, we can all agree, terrible.

Good point, CountryMidwife. However, not every hospital has a 33% C/S rate--ours is closer to 15%, including repeats. I think we should be working to lower C/S rates AND we should be doing more to promote VBAC. Yet I hope women would not be motivated solely by a desire to avoid C/S in choosing a home birth.

Thanks for participating in the dialogue.

Another confounding and immeasurable variable when comparing hospital vs. out-of-hospital outcomes has to do with future risk. We know that a scarred uterus significantly increases risks to future childbearing. With nearly 1 out of 3 women in hospital being delivered surgically, these women face future morbidity and mortality rates that are likely to be higher than those who chose not to be in hospital. Can I prove that? Not yet. But does 1 + 1 = 2?

I appreciate the chance to dialogue and suspect that no one wants an interminable thread. I think that unlike ACOG and the AMA, we all respect the right of women to chose where to birth, and that's the first and most important point.

I'm sorry you chose Dr. Freud, of all physicians, to emulate.

Regarding the evidence for safety of home birth, I think we approach the interpretation of the studies you cite differently.

The BMJ study, while using the most rigorous methodology possible given the topic under study, still relies upon self-report and opt-in by participating midwives. Given that home birth rightly takes place in the presence of only those people a woman wants at her birth, and not trained observers, this is appropriate. I still see it as a major barrier to conducting a satisfactory study on the subject.

There is also a problem in comparing the hospital outcomes between women who transfer from home and women who elected to have a hospital birth to begin with. The comparison group in this study is a subset of data from a national registry; the women in this group were not contacted for their self-report of the experience. Neither were their birth attendents. We therefore can't know what factors compelled them to plan a hospital birth over a home birth, or whether this decision was motivated by some underlying greater risk (diabetes, hypertension, other comorbidities). The hospital sample of singleton, vertex births at greater than 37 weeks does not specify whether other comorbidities were present.

As for the Karolinska study, I believe you mean the study was conducted in Australia, not in the hive of unethical barbarism that is Sweden. In any case, the study compares randomization of low-risk women to midwifery vs. standard obstetrical care within a hospital. It therefore does not specifically examine home birth compared to hospital birth. The study found excellent outcomes within the midwifery group, which I do not dispute. I think the midwifery model of care is wonderful, and my own practice style is much more aligned with midwifery than obstetrical medicine. However, I do not believe you can generalize from hospital-based midwifery to home-based midwifery outcomes. Hospital-based midwives have all the monitoring equipment, invasive and noninvasive testing, and subculture-specific concerns that hospital-based physicians do. Of course, they choose to use these resources less frequently, and perhaps more appropriately, than their physician colleagues. However I do not think you can generalize from the practice style and outcomes of hospital-based midwives to the potential outcomes of home-based midwives. This is a topic on which I'd like to hear more opinions from both types of midwives.

I do not dispute the notion that a home birth can result in a maternal/infant outcome that is as desirable and more satisfying to the mother and her family. I am a supporter of home birth for low-risk women for this very reason.

My purpose in writing about these topics on this blog is to encourage dialogue between participants from all sides of the issue. To that end, I require a respectful approach from all commenters. Whether or not anyone respects me or my profession is something I cannot control and therefore not at issue here. The environment of this blog, and its comments, is a matter of concern. I will remove any flames or off-topic comments, but I am not removing yours, Nata Invicta, because I think you have something important to offer to the dialogue and you obviously feel passionately about the subject. I only ask you to consider the tone of your comments, and whether they advocate for the women and midwives you support. There are some readers of this blog who are trying to educate and inform their opinions of home birth an other birth practices, and I suspect they will draw more influence from your comments if you deliver them with less invective.

"As for your response to momwithastethoscope's comment, I will say only this: it is the last refuge of a losing argument to attack the psychological foundation of your opponent's position."

Hmmmm . . . that's a technique I learned from a physician, S. Freud.

Your understanding of the data is quite shaky, I'm afraid. Studies that show the safety of homebirth include carefully conducted prospective cohort studies that control for risk (as best as possible).

Your grasp of Western ethics is shaky. Nice randomized, controlled studies concerning modes of midwifery care have been performed in that hive of unethical barbarism, Sweden.

I'm so glad, Doctor, that you haven't infected any of your patients with flesh eating bacteria and that you've limited to an acceptable number (at least to your self-congratulatory self) the amount of drug errors and mixed-up babies.

You seem upset, Doctor, that people don't respect you, your posters, and, indeed, your profession. Well, given that we spend 17X what Albania does per capita on health care and have average life expectancy of only 2-3 years longer . . . . and given the resistance doctors put up to cheaper, less invasive substitutes for their "skills," I don't think my attitude unwarranted.

Thank you all for commenting, although I will ask that readers from ALL sides of this issue address each other respectfully and reflect upon their own assumptions *about each other* as well as their assumptions about birth philosophies.

As I have said in several posts, I am supportive of home births for low-risk women. I plan to write more about my position in future posts.

However, I agree with momwithastethoscope's observation that many women/parents appear to be motivated by an ideological agenda in the decisions they make about birth and childrearing.

I also agree that a woman should have ongoing discussions about the risk/benefit scenario of choosing a hospital or a home birth. I tend to sympathize with people who are suspicious of hospitals and I am willing to recognize that a home birth may be a more acceptable set of risks, as Nata Invicta points out, than the set offered by a hospital birth. I think the evidence for safety of home vs. hospital birth is tainted on both sides, and I *don't* think it helps the dialogue between birth choice advocates to let the dialogue degrade into a battle between whose-evidence-is-best.

There is no way to conduct "best evidence" studies of home vs. hospital births. Simply put, women will not be randomized into a birth experience. This violates all tenets of Western ethics. This is the ultimate limitation to the hospital-birth proponents view. However, the home-birth proponents tend to cite evidence of higher M&M in hospitals that, I believe, fails to take into account that hospitals are referral centers and therefore likely to receive mothers and infants who have a higher baseline risk than those who birth at home.

In any case, I think there are faults on both sides of the argument and I think it is a mistake to let the debate degrade into jargon, statements of ideology, and name calling.

Nata Invicta, I would like to reassure you that I have been a staunch advocate for vaginal deliveries in my community, and have never given in to recommending a C/S for no good reason. I do not routinely cut episiotomies. None of my patients have been infected with flesh-eating bacteria. There have been a few cases in which my patients have received the wrong medication, but these did not result in any lasting harm and occurred in less than 1% of my cases. There was a single incident in which a woman was given the wrong baby to nurse, at my residency hospital, and indeed this was a "never event," but against that fault I was proud to have contributed to the safe delivery of >3,500 infants per year at that hospital, mainly to undocumented and low-income women who received excellent care and had complication rates well below national averages. And yes, I did introduce medical students into the care of these women because that is how you learn to respect and honor labor and birth: by being present, observing, and participating.

As for your response to momwithastethoscope's comment, I will say only this: it is the last refuge of a losing argument to attack the psychological foundation of your opponent's position.

All are welcome to comment on this blog, but I require respect for opposing views.

More nonsense but financially motivated guild monopolist physicians.

First, "There are NO proper peer revied RCT that demonstrate the safety of home birth over hospital birth."

Ha, ha! Is that the standard you hold all your procedures to? You'd be out of business, I'm sure. Why is it only non-physicians must be evidence based.

Notice how you frame the debate. By your own admission, there is no peer reviewed RCT evidence that hospital births are safer than home births. Given that it is A FACT that hospital births involve cutting opening women's uterusues, slicing their vaginas, infecting them with flesh-eating bacteria, mixing up their babies, giving them the wrong medicines, forcing their bodies to be unwilling manikins for manipulation by med students, etc., it would seem that you would evidence that hospital births are safer. THERE IS NONE. As a consumers, all we have is a choice between different sets of risks. No one knows which is "better."

Second, pediatrician-woman, the "baby's health" is not the only object in birth. That's vile sexist Victorianism--when doctors would risk the mother's life so that she could produce children for her husband-master. Mothers and babies are party of a shared process--a process of shared risk in which both of their well beings must be considered. To assert otherwise, as you do, indicates the hatred you bear towards your own sex or perhaps some deep, unresolved psychological problems you have with motherhood.

Sounds like hyperventilation and alkalosis.

No obfuscation please ruralmidwife!
There are NO proper peer revied RCT that demonstrate the safety of home birth over hospital birth. Anecdote does not equate to evidence no matter how you try to spin it re the risks of hospital birth. Talking about good outcomes is NOT science - it is village shaman type hogwash.

"The safety lies in choosing a quality professional midwife, her having a rigorous risk assessment before and during labor, an effective transport system, and a collaborative team on the hospital end so that care can be rendered seamlessly"

This statement is dubious at best - much of the danger is inherent in the process regardless of the "rigorous risk assessment" and as some of my midwifery preceptors always said:
Normal delivery is a retrospective diagnosis .
As to the transport process - 5 minutes can mean the difference between life and death - is there a Bell Jetranger on hand at every home delivery?
Sweden has recently stopped their " flying squad" response system for home deliveries as their M&M stats were similar for "low risk" home deliveries when compared to stats for high risk centers. Despite this , I have NO objection to women delivering at home , provided:
a. They are properly informed of the actual risks.
b. I am not expected to pick up the pieces when things go pear-shaped (as if!)
The decision for home delivery should be an informed one and not an ideological one.

Re "experienced witnesses": to be fair, I would bet that L&D nurses, in the crisis of the moment of alleged seizure, would not be able to fully recount details of mom's posturing either. You know how those things become a clusterbeep in hospital!

I want people who rally for the safety of hospital birth (vs home birth) to realize that said benefit of hospital environment does not occur in the majority of hospitals, especially in rural areas. Unless you have docs, anesthesia, OR, and NICU in house 24/7, there's no more safety than in a homebirth. Yes, we have to get our ladies into the hospital, but you have to get your docs and team in as well.

The safety lies in choosing a quality professional midwife, her having a rigorous risk assessment before and during labor, an effective transport system, and a collaborative team on the hospital end so that care can be rendered seamlessly.

Do address some of the risks of hospital birth, sometime if you will Rural Doc. And talk w/ your community midwives about all the GOOD outcomes too!

This mother didn't sound nearly as frustrating to deal with as Dahlia. At least when you got the drill Sargent there she responded.

Was this mother going to breast feed?
I guess that's a story the Pediatrician will write.

As the pediatrician, I am on the receiving end of this story. I often don't get to hear the inside track of a mom's labor. Like you, I focus on my patient. But I am perturbed when mothers come to this process with an agenda - spoken or otherwise. Often these agenda seem to be much more about what this person wants than what is best for both mother AND baby. We're seeing this in the media more as celebrity mothers have become "too posh to push" (a borrowed phrase from Time magazine)and opt for c-section delivery because it suits their schedules. The agendas often don't stop with delivery - there are many expectations that the baby won't spit-up, sleep through the night from the first night home, and generally behave like a doll. It's a rude awakening to some parents that newborns are people, too. Thoroughly enjoyed your post and look forward to more!
