USA – High Rate of Caesarean Births – Nurse-Midwives Respond

(WOMENSENEWS)–At 30 percent of all deliveries, the current national
Caesarean-section rate in the United States is twice the 15 percent
maximum rate recommended by the World Health Organization and three times
the preferred rate cited by many researchers.

All of which Dr. Bruce Flamm, an obstetrician with Kaiser Permanente in
Riverside, Calif., says is remarkable.

But he isn’t sure if it’s remarkably good or remarkably bad.

Flamm says that notwithstanding the WHO recommendation–which followed
the same official U.S. health recommendations in the Healthy People 2000
initiative–there isn’t enough data to say what the appropriate C-section
rate should be.

“Some of my colleagues think it should be higher,” Flamm says. “I have
heard some doctors say that all women should have babies by C-section,
that vaginal births are archaic. Some docs have a C-section rate of 50
percent because they believe in their hearts it’s the best thing for their
patients.”

Flamm does not include himself in the group of doctors who think
vaginal births are archaic, but he does agree with the October 2006
recommendation by the American College of Obstetricians and
Gynecologists–to which he belongs–issued against out-of-hospital
births.

Even though the chance of something going wrong is very small, Flamm
thinks it’s safer to have all necessary equipment and personnel
immediately available in case of an unforeseen emergency, which can happen
even in low-risk pregnancies.

The physician organization’s recommendation–combined with the rising
rate of C-sections–is a hot topic among midwives.

Nurse-Midwife Protest Letter

The American College of Nurse-Midwives sent a letter in late November
2006 to the physician’s organization taking issue with the idea that
safety could only be provided in a hospital.

“The safety of birth in any setting is of utmost priority,” the letter
read. “The implication that there is insufficient evidence to support the
safety of planned out-of-hospital birth is unsubstantiated . . .
Furthermore, we are not aware of evidence supporting the assertion that
the hospital is the safest setting for labor, birth and the immediate
post-partum period for low-risk women.”

The letter went on to say that by discouraging support for
out-of-hospital birth providers the organization’s position could harm the
culture of safety around birth, for patients and providers. It appealed
for collaboration to ensure women’s safety.

Stacy Brooks, a spokeswoman for the physicians’ organization, says the
decision to recommend only hospital births was not based on data showing
home births are dangerous, but just to minimize any possible
complication.

The midwives’ organization, on the other hand, lists multiple studies
on its Web site supporting the safety of home births.

One large study, published in June 2005 by the British Medical Journal,
concluded that the safety of “planned home birth for low-risk women” in
North America involving certified midwives “was associated with lower
rates of medical intervention but similar mortality to that of similar
hospital births.”

Many midwives also say that the growing preference for hospital
settings automatically leads to unnecessary and often uncomfortable
interventions. A prime example is the fetal monitor, which Flamm says he
thinks is used on virtually all women who labor in hospitals.

Fetal Monitors Studied

Meredith Goff, a practicing midwife on the faculty of the Yale School
of Nursing, is writing a paper about the reliability of fetal monitors
versus the old-fashioned fetoscope.

The former is an electronic device, usually attached to the outside of
a woman’s belly and less often attached through the vagina to the baby’s
head. The latter is a hand-held instrument a medical provider moves over
the women’s belly to periodically check the baby’s heartbeat.

“There is absolutely no evidence to support continuous fetal monitoring
since it came about in the late 1960s,” Goff says, “yet in 2002, it was
used on 85 percent of women in labor in the U.S. It’s the most commonly
performed obstetrical procedure. And every professional organization
agrees there is no evidence of its usefulness.”

In fact, she says, the procedure has a very high false positive rate,
meaning that in most cases when the monitor indicates fetal distress, the
baby is fine. “So we’re doing all these C-sections for no reason because
we can’t divorce ourselves from this technology,” Goff adds.

One of the trends that many midwives find particularly troubling is the
decline in vaginal births after Cesareans.

They point to a June 2006 study by researchers at the University of
Utah of more than 30,000 women. Published in Obstetrics and Gynecology,
the study found several serious complications, including hysterectomy and
the need for a major blood transfusion, increased significantly with each
C-section.

Dr. Robert Silver, chief of high-risk obstetrics at the University of
Utah, is the primary author of the study. Only 9 percent of babies born to
a woman who has had a C-section are delivered vaginally now, down from 30
percent a decade ago.

“Vaginal deliveries after a C-section are pretty safe, the risk is
quite low,” Silver says, “but I think people have gotten scared off.”

Downsides to Both Options

Silver says there are downsides to both options. Vaginal deliveries can
damage the pelvic floor, possibly leading to urinary and fecal
incontinence and pro-lapse (in which the pelvic organs descend, causing
discomfort). C-section births lead to more maternal morbidity, increased
recovery time, less bonding and more difficulty with breastfeeding.

Paula Cate, a midwife who’s delivered more than 4,000 babies in 28
years, says a factor in the rocketing rise of C-sections is the economic
incentives of highly skilled medical specialists favoring a high-tech
birth, like the rise in the participation of anesthesiologists in even
routine births.

“There are now lots of places where there are anesthesiologists on the
labor and delivery floor, but when I started in 1978 that wasn’t true; you
had to call them to come,” says Cate.

Midwife Deborah Cibelli argues that C-sections are being driven by a
fear of lawsuits. “It’s a rare provider who gets sued for doing a
C-section,” she says, “but if there’s any outcome that’s less than
perfect, you can get sued for not doing a C-section.”

With the cost of malpractice insurance for both midwives and physicians
skyrocketing, many providers find it more prudent to do C-sections if
there’s any hint–however remote or even mistaken–of complications.

Midwives say current popular culture does little to subdue the sense of
danger and complication surrounding childbirth.

Cibelli, for instance, says “The Baby Story,” a program on the Learning
Channel that shows labor and birth experiences, recorded several of her
patients delivering their babies in the hospital, but none of them was
shown.

“The filmmakers told us that mine were just too normal. What really
sells is drama. They love the rushing down the hallway to save the baby’s
life to do a C-section. Mine were quiet, with dimmed lights. The people
filming thought they were wonderful, but they knew they were not going to
sell because they were not sensational.”
