Vaginal Birth Best 85% of the Time? Why Did Tuteur Claim C/S Rate Too High?

In the discussion on the post, A Midwife and an OB Walked into a Blog, Amy Tuteur provided a very evasive answer to my request that she defend her statements made about the cesarean rate being twice what it should be. I am creating a new post so she will have the opportunity to clarify how she arrived at the conclusion that there is an ideal cesarean rate.

 

It began with this comment by me:

It is truly a shame that the option for breech, VBAC and twin delivery have been reduced to almost nil in American hospitals. If anyone meets a care provider who dedicates their career and bears the additional risk (and costs*) of liability to give women choices, please tell them they are doing a good job. They need to hear it.

*costs of insurance and TIME. VBAC= lots of time spent at hospital while patient labors

 

There were some comments that followed which challenged my belief that it’s a shame, so I addressed them.

Why is it a shame?

The shame isn’t the numbers or the drop in vaginal birth. The shame is lack of access for the patients and their doctors (and midwives) that comprise the numbers.

A few OB-GYNs have written about their lament of the state of maternity care of late and their thoughts echo the conversations I have had over the last year or two with other OB-GYNs. Drs. Fineberg (An Obstetrician’s Lament) and Plante (Lament, in Stereo) summed up their concerns about the direction in which things are headed and why no one should really be that surprised if women start looking around for alternatives to an automatic cesarean if surgery is not their preference.

While I know some like the idea of midwives as laborists with an OB backup for emergencies, others really want the chance to practice obstetrics as they were trained, not just saved as cesarean machines.

I don’t ever hear anyone talk in extremes like Amy, demanding that everyone acknowledge the rightness of obstetrics or the wrongness of midwives, even if they are adamantly opposed to the notion of home deliveries. I hear more stories of devastating, life-altering lawsuits, the emotional effects of bad outcomes, the loss of family time, sleep and health because of the demands of the profession, the efforts made to keep patients happy when some are chronic discontents, the challenges of working with high numbers of obese patients and dealing with any and all comorbidities while trying to get a baby safely in their arms, managing a practice and having to be a business person on top of it all, how difficult it is to counsel patients and have them understand that to which they are consenting when the ABSOLUTE risk associated with two options is very low, frustration with colleagues that section and induce right and left and how at some point, somewhere along the path, the art of obstetrics got swapped out with scheduled cesareans for factors unrelated to patient preference. The ones that have been around long enough watch best evidence flip flop back and forth and just seem to be unimpressed by some stupid raging internet debate. Like the honey badger, they don’t give a shit.

Amy has taken a very extreme position on the number of cesareans performed and I don’t agree. In her book, How a Baby is Born, she calls a 20% rate “too much of a good thing.”

Nonetheless, it is possible to have too much of a good thing. The odds are as high as 1 in 5 that Caesarean section will be recommended to you. How will you know if it is the right procedure for your situation? How can you avoid having an unnecessary Caesarean section? The first step toward answering both questions is to understand exactly what a Caesarean section is—and when it is recommended.

She called a sub-30% cesarean rate “at least twice what it should be.”

The C-section rate is rapidly approaching 30%. That’s at least twice what it ought to be, and last I heard babies have not doubled in size and fetal distress has not doubled in incidence. If that’s not defensive medicine, I don’t know what is.

If that’s not a wildly disingenous philosophical flip-flop, I don’t know what is. Between 2006 and today, Amy went from offering biting criticism of obstetricians for practicing defensive medicine and performing what she feels are twice as many cesareans as they should to arguing the points here on this thread. Why the change, Amy? I have long been curious about why you changed your tune.

I can’t speak for Amy, but one thing that happened between 2006 and now is the 2009 release of “Monitoring Emergency Obstetric Care: a handbook.” The WHO wrote: “Both very low and very high rates of caesarean section can be dangerous, but the optimum rate is unknown. Pending further research, users of this handbook might want to continue to use a range of 5-15% or set their own standards.” … “Earlier editions of this handbook set a minimum (5%) and a maximum (15%) acceptable level for caesarean section. Although WHO has recommended since 1985 that the rate not exceed 10-15%, there is no empirical evidence for an optimum percentage or range of percentages, despite a growing body of research (and the research they list here isn’t all that convincing) that shows a negative effect of high rates.”

I had always assumed that the number quoted by the WHO had its basis in some sort of meta-analysis, but apparently it didn’t. That was enough to make me suspicious of 10-15% as an ideal rate.

We’ve discussed this many times, Jill. If NCB advocates want to increase access to vaginal breech and VBAC, they’ll have to stop whining that it is some sort of giant conspiracy on the part of obstetricians to get to the golf course, and they’ll have to start acknowledging that more liberal policies of vaginal breech and VBAC will increase perinatal death. You can’t begin to address the causes of the rising C-section rate if you refuse to acknowledge what they are.

Personally, I think the best solution would be no-fault compensation on the order of the vaccine fund. We know that vaccines will kill some children and leave others brain damaged, but the overall vaccines save massive numbers of lives. Therefore, we automatically compensate those who can prove they were injured by vaccines. Similarly, we KNOW that more liberal policies on vaginal breech and VBAC will kill some babies and leave others brain damaged. Unless and until society (and NCB advocates) are willing to acknowledge that certain choices will inevitably lead to preventable neonatal deaths and absolve obstetricians of responsibility for those deaths, nothing is going to change.

Amy, to be clear, you are holding to your claim that the cesarean rate at 30 percent was twice what it should have been?

On what specifically were you and are you basing this claim in both examples? Was there a study in particular or did you conduct your own research?

In other words, the rate is currently more than twice what it should be in your opinion, however, we can’t expect to return to this ideal rate unless we understand the issue and are prepared to accept the consequences.

Alexis, that is a good example. I can think of several other reasons why the idea of claiming as Amy has that there is an ideal rate, especially one of 15%, is problematic. Is Amy’s assertion that vaginal birth would be better than cesarean section more than 50% of the time based on anything substantial or does she have “other ways of knowing” that it’s just too high?

AHRQ looks to Canada in its measure summary:

Caesarean section rates provide information on the frequency of surgical birth delivery relative to all modes of birth delivery. Since Caesarean section delivery increases maternal morbidity/mortality and is associated with higher costs, Caesarean section rates are often used to monitor clinical practices with an implicit assumption that lower rates indicate more appropriate, as well as more efficient care.

I am interested in knowing why there is an implicit assumption that lower rates are better. Is this measure even worthwhile? Why?

 

 

Philosophies can change dramatically when presented with new information, so I would like to assume this is the case. I wanted to make sure that Amy had a forum to explain her position or why she flip-flopped so dramatically.

 

Appeal to Decency: Hey readers, I know Amy leaves Professor Dearest comments like this sometimes, but I am requesting that you be respectful even in your anonymity.
