BIAS IN OBSTETRICS

 BTCanada would like your help.  We want to hear from mothers, regardless of how or when you had your child(ren), about bias in obstetrics and how it impacted your decisions and your life after childbirth.   What things were you told were true only to find out that they weren’t for you? Please drop us a letter or an email.  Please specifically state that your comments are about bias in obstetrics.  We will not reply to your comments unless you specifically request that.

The medical definition of bias is ‘any trend in the collection, analysis, interpretation, publication or review of data that can lead to conclusions that are systemically different from the truth.’

Bias is also defined as ‘an attitude that inhibits impartial judgment or an unfair policy stemming from prejudice.   It is an error caused by systemically favouring some outcomes over others.’

There are no shortages of bias in obstetrics, both now and in the past.  When we’ve had a chance to hear your voices we will publish an article highlighting them on this page.

BIAS IN OBSTETRICS

Penny Christensen, Chair, Birth Trauma Canada

 
Bias induced myopia and naiveté is used as an excuse to disregard women’s rights.  “But we didn’t know” becomes their mantra when they are caught in their lies.  And for some this is true.  There really are people so stupid they can’t figure out they are stupid and there is no cure for ignorance in this case.  They are hapless victims of their conditioning and training.  Most bias can’t trace this as its only source.  Most ‘stupidity’ is inexcusable.  Claiming ignorance is hollow and indefensible.  Most people guilty of perpetuating obstetrical myths and bias aren’t naïve and they have the intellectual capacity for reasoned thought.   They just don’t use it.  They have the ability to see cause and effect.  They have first hand knowledge of it and they have had for decades, even centuries.  Some recognize this and are too afraid to speak up lest they be ridiculed or ostracized for speaking the truth.  When those brave few do speak they are treated like lone voices in the wilderness but change doesn’t happen without them.
The most disheartening reason for perpetuating bias and myth in any form of systemic discrimination is also the most common.  They simply choose not to change their ways because their station in life is threatened if they do.  They hold tight to their attitudes.  When chinks start to appear in their armour they just beat their drums louder and with more viciousness.  It is why bias is so hard to overcome. They refuse to ask questions they don’t want to hear the answers to.  They conduct studies that ignore variables that discredit their hypotheses.  They pontificate endlessly without considering or caring about their victims’ experience.  It doesn’t occur to them to even ask.  In the face of credible evidence they shut their eyes tight, cover their ears and hum.  They blather on about supporting evidence-based science and empowering women but many of them do neither.  It is childish and unprofessional behaviour and it strips them of their credibility.   
Humans can always be counted on to preserve their own groundless sense of superiority over others.  People will elevate their own status by sacrificing the rights of others.  And this doesn’t take very long.  Put a group of equals in a room, assign one group to be the ‘controllers’ and the other group to be the ‘controlled’ and watch the degradation start to happen within hours.  Overall, we aren’t a very altruistic or superior species.  That doesn’t stop me from being optimistic about our evolution as a species.  I’ve just learned to temper my optimism with a heavy dose of realism.
Bias, and the discrimination it spawns, makes chumps out of educated people.  This is why education is only a partial remedy.  People need to know how to recognize bias, refuse to believe it and then resolve to banish it.  Bias exists without any credible evidence and often without a shred of common sense.  This isn’t the same as a lack of information supporting it.  There is usually no shortage of supporting blah, blah, blah, but, of course, not all information is valuable.  Bias hurts people, often badly and permanently.  Sometimes it kills them.  It robs people of their credibility and it blocks progress and advancement.  It is the reason our descendents will wonder of us “How could they be so moronic.  The truth was so obvious.  Why couldn’t they see it?”   It is the reason we ask the same of our ancestors.
What is true for some isn’t necessarily true for others.  A world without bias recognizes that.  Universal human rights give people the right to make their own decisions.  They do not give other people the right to make decisions for them.  Give women access to unbiased, intelligent information and let them make their own decisions.  Don’t assume they are not capable of that because they, most assuredly, are.

Consider these statements:

 1)  Cancer patients do not have the right to safe and effective pain control because pain is a natural consequence of cancer and cancer is a naturally occurring human condition.
2)  Those in burn units who are directly responsible for their injuries have no right to effective pain relief or compassion.  If they don’t like that choice they shouldn’t have burned themselves.
3)  Encourage surgical patients to forego pain relief both during and post surgery.    Instead, have a staff member providing one-on-one encouragement not to have effective pain relief.  Patients should be encouraged to think of their suffering as ‘a good pain’, to ‘work with the pain’ and to embrace ‘an altered sense of consciousness’.  Infer that anyone who wants pain relief is a weak minded failure.  Encourage competitive suffering with post surgery get-togethers.
4)  Hospital policy should ensure that all palliative care patients ask at least twice before their request for pain relief is considered.  If death is imminent consider denying the request.
5)  Trauma sustained during torture results in damaged bodies and damaged psyches.  Depositing a large sum of money in their bank account will make them forget all about it.
6)  Psychiatric studies show that pre-rape courses reduce the terror women feel during and after rape.
In a civilized society these statements would beggar belief, and with good cause.  They are offensive, insensitive and cruel. 
 

Now consider the same statements when they are made about pregnant women:


1)  Maternity patients do not have the right to safe and effective pain control because pain is a natural consequence of childbirth and childbirth is a naturally occurring womanly condition.
2)  Those women who get pregnant should not expect choice in delivery options, nor should they expect pain relief or compassion.  If they don’t like that they shouldn’t get themselves pregnant.
3)  Encourage obstetrical patients to forego pain relief during and after childbirth.  Instead, have a staff member providing one-on-one encouragement not to have effective pain relief.  Patients should be encouraged to think of their suffering as ‘a good pain’, ‘to work with the pain’ and ‘to embrace an altered state of consciousness’.  Infer that anyone who expects effective pain relief is a weak-minded failure.   Encourage competitive suffering with post birth get-togethers. 
4)  Hospital policy should ensure that all obstetrical patients ask at least twice before their request for pain relief is considered.  If birth is imminent consider denying the request.
5)  Trauma sustained during childbirth results in damaged bodies and damaged psyches.  As soon as you put her baby in her arms she will forget all about it.
6)  Psychiatric studies show that pre-natal courses reduce the terror women feel during and after childbirth.
These statements should beggar belief but they actually reflect obstetrical attitudes for the past several decades and, in many obstetrical circles (this country included), they are still widely accepted.  Such attitudes maintain a deplorable status quo.  They prevent advancement.  Systemic discrimination always involves the attitude that a certain sub-group of the population is not deserving of humane treatment.  They are considered inferior.  What is considered unacceptable for other humans is considered acceptable for the group discriminated against.   This is true for any form of systemic discrimination, whether it is based on race, ethnicity and, in this case, gender.  Underlying all obstetrical bias is misogyny. 
Only recently have some obstetrical associations around the world back-tracked from their long held views that childbirth is the only situation where patients can be denied pain relief, under the care of a physician, when safe and effective methods of pain control are available.   
 

A)  Childbirth is healthy

Childbirth is NOT healthy.  It isn’t now and it never has been.  I’m not sure if people who say this are being wilfully deceptive or just plain stupid.  The end result is the same.  Women are not well served by this bias.  Women told this preposterous statement by people who know better, or should know better, have unrealistically high expectations about motherhood and the childbirth experience. 
When fertility rates go up so does the rate of women’s health problems.  Parity is directly related to urinary incontinence, anal incontinence, uterine/vaginal/rectal/urinary prolapse, sexual pain and/or lack of sensation during intercourse, chronic pelvic pain and neurological problems throughout the body.  Parity is also associated with heart disease, diabetes, gallstones, thyroid disorders, Alzheimer’s disease and a number of different cancers (breast cancer, renal cancer, etc.)  Having children for women is also associated with obesity – and all that entails.   Women who have children have much higher unemployment rates and this puts them at higher risk for living in poverty.  And don’t even get me started on the effects of stress.  None of this stuff is healthy. 
Ignoring or dismissing the obvious maintains the status quo and affords no hope for positive change that will improve women’s short term and long term health.

B)  Childbirth is natural (and therefore good) 

Nature isn’t just about fuzzy puppies and rainbows.  Nature is also cruel, unfair and tragic.  None of the people who espouse this obstetrical bias that I have met, to date, are willing to live in caves and forego the technological advancements that enhance their lives.  Humankind exists solely because we can use our brains and ingenuity to counteract nature and none of us would last very long in nature.  We can’t run very fast, we can’t see or hear very well, we have no body covering to protect us from heat, cold, insects and the sun’s radiation.  We are susceptible to all kinds of infectious and non-infectious disease.  The human body is not a superior design.  We need our brains, ingenuity and technology to survive.

Over 500,000 women die directly of childbirth every year.  Most are in the developing world because they do not have access to life saving medical technology and qualified obstetrical care.  Many, many more suffer life altering morbidity problems.  In the developed world we have less maternal mortality and far more ‘near misses’.  My point is that just because something is natural doesn’t mean it is safe.
For those who feel that if it is natural it must be good, consider all the things that are natural and definitely not good for you:
Tornadoes, earthquakes, tsunamis, mudslides, floods, hungry polar bears, any other predatory animal, spiders the size of dinner plates (Really. In Australia. Ewww), poisonous spiders, poison ivy, poison oak, any other poisonous plant, those big snakes than can crush you, HIV, tuberculosis, those ticks that carry Lime Disease, mice that carry Hantavirus, any other infectious disease, marauding elephants, cyanide, arsenic, radon, hurricanes, death, botulism toxin.  You get my point. 

C)  A healthy woman’s body knows how to give birth

Does a healthy man’s body ‘know’ not to have prostate problems?  Does a healthy child’s body ‘know’ not to get cancer?  To suggest they do is both ludicrous and cruel.  Bad things happen to people everyday precisely because their bodies don’t ‘know’.   As addressed above, the human body isn’t an anatomical wonder.  Men have urethras that pass through the prostate gland – a gland that gets bigger as they age, restricts urine flow and has a strong tendency to become malignant.  Some children are born with a pre-disposition to cancer and other sad genetic afflictions.  It is not their fault.  It is not a woman’s fault either when things turn bad during childbirth.  We are the only species where birth involves pushing an infant that is too large through a space that is too small.  There is no better way to make someone feel like a failure than to pump up unrealistic expectations about what their bodies are capable of.  The role of medicine and technology is to address these inadequacies and to make us healthy and keep us healthy despite anatomical deficiencies.
Cemeteries prior to modern medicine are full of healthy young women and their babies whose bodies didn’t ‘know’ and who didn’t make it.  These tragedies still happen today but no where near the same numbers.  Today they are ‘near misses’.  None of these women are failures.  Those who don’t make it are tragic victims.  Those who had near misses are survivors.

D) Childbirth is only painful if a woman thinks it will be painful.

 Good grief.  Childbirth is painful for the same reason kidney stones are painful or surgery without anesthesia is painful. Pain stimuli activates neurotransmitters responsible for pain.  They transmit that information to the brain and the brain responds.  Fear is an adaptive response to pain.  Without this association we would never learn who or what to trust and what dangerous things we should avoid.  Telling someone to relax while they are suffering immensely is maladaptive and counter-intuitive.  It is another way to make women feel like failures.  Why this bias developed with respect to women and childbirth speaks more about disregard for women than rational thought.

E)  Non-pharmaceutical methods are effective pain relief

There are two effective ways to relieve pain.  Both are pharmaceutical.  The first is to prevent pain messages from reaching the brain (like a spinal and/or epidural) and the second is to mess with how the brain receives pain messages (like opium derivatives).  The second way has serious drawbacks.  Doses large enough to provide complete pain relief for the mother would kill the baby, and likely kill the mother.  Any dose alters the mother’s perception of reality. 
Breathing techniques, water baths, massages, having someone in your face with ‘encouragement’ and going to your happy place do not relieve pain.  They layer other sensations on top of pain or give you something else to think about while you are suffering.  If these techniques actually relieved pain anaesthesiologists would be all over them in other areas of the hospital.  You would read headlines like:

“Man passes kidney stones painlessly over three days, without morphine, relying solely on his Kidney Stone Passing support person and breathing techniques.”


 “Anesthesiologists are shocked by pain-free open heart surgery performed without anesthesia in the Jacuzzi.  Patient sipped herbal tea and chatted with the surgical team during surgery.”

“Anesthesiologists outraged that aroma therapists are replacing them.”


Not going to happen.  

F)  Childbirth is painful because women need to be punished for being women. 

 This is un-adulterated misogyny and still widely accepted.

G)  Women need to suffer to be good mothers

Same comment as above.  If this were true we wouldn’t hear from good mothers who didn’t suffer and from good mothers who did suffer whose babies serve as a trigger for traumatic stress symptoms and who struggle with the tremendous guilt that brings.

H)  Women need to reach an ‘altered state of consciousness’ to properly give birth.

This ‘altered state of consciousness’ is dissociation and dissociative amnesia.  It is a human response to severe psychological and physical stress and it should be avoided, not encouraged. 

I) It is a woman’s fault if she has a miscarriage or her baby has a birth defect.  She must have done something wrong.

15% of pregnancies end in miscarriage.  2-3% of babies born will have a birth defect.  They are not caused by eating pineapple, having a glass of wine with supper, watching acrobats, bathing, full moons or any of the other preposterous and blaming theories out there.  Heaping this kind of guilt on women who are struggling with pregnancy loss or struggling with the burden of coping with congenital defects in their children is indefensible.

Developmental biology is a complex science.  There are numerous chances for errors during fetal development.  A woman cannot control her genetics or those of her fetus. 

J)  A healthy baby is enough to make up for the trauma of childbirth

A prize, no matter how wonderful, does not cure physical or psychological trauma in any situation.   Offensive statements like this isolate and further traumatize all trauma victims.  Monetary compensation does not end PTSD for torture survivors.  You don’t tell someone who has lost his legs that he should be happy he didn’t lose his arms.  It is no different for women after childbirth.  The experience of childbirth and the baby are two separate things. The attitude that a healthy baby makes women forget the trauma of their childbirth experience is patently untrue.  Women carry that experience with them for life.  Fatalism and stoicism are not the same as getting over it.

K)  Cesarean surgery on demand will have disastrous social and financial consequences for health internationally”

Blaming women who choose cesarean section for destroying the social and financial fabric is vicious.  Heck, let’s blame them for conflict in the Middle East and pine beetle deforestation as well.  It would make as much sense.  Those with specific biases often use words like ‘empowerment of women’ and rail against ‘views not supported by evidence’, when they, as in this case, are guilty of the same transgressions.  Scare mongering and manipulation are not empowering to anyone other than those wielding power.  Denigrating those who don’t agree with your point of view is not respectful, to women or anyone else. 

When I was first made aware of the source of this statement I was speechless.   It is a direct quote from the Canadian Midwives Association found in their rant against maternal request cesarean section.  I was not expecting such a visceral, inflammatory attack on a woman’s reproductive choice and autonomy from an association of women who fight so hard for a woman’s right to choose a less managed childbirth experience.  We can’t blame patriarchal misogyny for this.  This is blatant woman on woman abuse. 

I want to make it clear that not all midwives think this way.  I’ve talked to some who find this stance as repugnant as I do. 

I strongly support a woman’s right to choose.  Midwives have been maligned and controlled for centuries and I can’t blame them for feeling a bit scrappy.  They provide a professional service strongly desired by some women who have every right to make that choice and that choice should be fully funded but a midwife-attended vaginal birth is not the only acceptable choice women can make. The choice any woman makes is the right one for her and should be respected, not denigrated.

L)  Episiotomies are necessary to protect the pelvic floor.

This bias was once widely held.  Millions of women around the world were subjected to routine episiotomies for decades in the belief that cutting the perineum would have a better outcome for the pelvic floor than spontaneous lacerations.  Studies supporting this bias appeared in medical journals and doctors and nurses everywhere believed this.  There was lots of information to support this stance but not a shred of credible evidence.  That is the nature of bias.  Deliberately damaging the pelvic floor to save the pelvic floor is as inexcusably stupid in hindsight as it should have been during the decades women were subjected to routine episiotomies.  

M)  If it is in a medical journal, it must be true. (Or how to recognize a spin doctor)

This simply isn’t true.  Many medical journals (particularly with respect to childbirth) are propaganda vehicles for a particular bias.  One estimate states that only 0.1% of all medical studies published every year can claim to be both scientifically sound and potentially relevant to doctors and patients.  There are many days when I think that estimate is overly generous.  Dr. Richard Smith’s The Trouble with Medical Journals [RSM Press, 2006] provides insight about this serious problem.  Integrity in medicine remains as elusive (and worth fighting for) as integrity in any other business. There are people working hard to support genuine evidence-based obstetrical information, more humane treatment of pregnant women and factual accountability and transparency.  More power to them.  It has been, and continues to be, an uphill struggle.

How can you distinguish the bad from the good?  It is a problem even those with an understanding of the scientific process struggle with.  One of the first ways to educate oneself about the prevalence of obstetrical bias is to read archived obstetrical journals.  With the benefit of hindsight the bias (and related misogyny) presented in many of these published studies practically jumps off the page.  How do you recognize bias without the benefit of hindsight?  I’ll take one study and dissect it to show what tools of deception are used.  You can look for the same in other studies.

I’ve chosen ‘Maternal mortality and severe morbidity associated with low-risk planned cesarean delivery versus planned vaginal delivery at term’.   It is authored and championed by the Public Health Agency of Canada; the Department of Obstetrics and Gynaecology, University of British Columbia, Vancouver; Perinatal Epidemiology Research Unit; Department of Obstetrics and Gynaecology and of Pediatrics, Dalhousie University; the Faculty of Nursing and Department of Obstetrics, Gynecology and Reproductive Sciences, University of Manitoba; Departments of Pediatrics and of Community Health Sciences, University of Calgary; and the Departments of Pediatrics and of Epidemiology and Biostatistics, McGill University, Montreal.  The lead author is Shiliang Liu.  It was published in the Canadian Medical Association Journal (CMAJ) Febraury 13, 2007.
 Supposedly illustrious connections, to be sure.
 Their conclusions were that planned cesarean deliveries (PCD) had higher morbidity rates than those associated with planned vaginal deliveries (PVD) when comparing healthy pregnant women at term.

 This was a surprising conclusion to me.  I have read many medical studies comparing PCD with PVD that arrive at the opposite conclusion – both in North America and around the world.  The National Institute of Health (United States), in a statement about maternal request cesarean section, concluded that the quality of evidence available wasn’t good enough to say which was safer for the mother – an uncomplicated PVD or an uncomplicated PCD.  How then, can different research scientists arrive at such diverse conclusions?  Rule #1 in recognizing bias in medical studies is:  Are there other better designed studies around the world that dispute the study in questions’ conclusions?  Could there be?  Is there controversy about the conclusions or results?

Rule #2 :  Look for study design flaws.

The U.K. instituted thromboprophylactic guidelines for cesarean deliveries in 1995.  Cesarean deaths (and morbidity) associated with thrombosis and thromboembolism declined sharply thereafter.  (The Society of Obstetricians and Gynaecologists of Canada – SOGC – wouldn’t follow suit for another 5 years.)  Other guidelines for better care of cesarean mothers were accepted and more widespread around the same time. [spontaneous vs. manual extraction of placenta, non-closure vs. closure of peritoneal layers, more reliance on regional vs. general anesthesia, etc.]  Any study seriously comparing mortality and morbidity rates associated with PVD and PCD would ensure advancements were accounted for in your study period.  This study purposely looked at 14 years of Canadian (except Quebec and Manitoba) restrospective data – from 1991 to 2005 - with the majority of planned cesareans prior to 2000.  This is a perfect example of how study design can be used to mask bias and skew results.

Rule #3:  Look for what they aren’t telling you as much as you look at what they are.

There is no better way to ‘prove’ your point of view than to ignore variables that don’t support your position.  Let’s look at the stuff they aren’t telling us.

Maternal Mortality:  This study concluded that ‘the difference we observed in in-hospital maternal deaths between women undergoing planned cesarean vs. planned vaginal delivery was not significant.’  (The emphasis is mine)  In reality no women died in the planned cesarean group whereas 41 (0.02%) died in the planned vaginal delivery group.  Are these deaths insignificant?  I wonder if they would have considered these numbers insignificant if a similar percentage of deaths occurred in the PCD group and not in the PVD group? 

How was maternal morbidity defined? 

*Hemorrhage requiring hysterectomy (0.03% PCD; 0.1% PVD)

Hemorrhage  requiring transfusion (0.7% PVD; 0.2% PCD)

Any hysterectomy (PCD 0.6%; PVD 0.2%) (not sure if this includes those women who had finished childbearing and required a hysterectomy for other medical reasons.  It is certainly easier to do this at the same time as a cesarean.  Requiring a hysterectomy after a vaginal delivery for the same reasons wouldn’t be captured in this data set as it would require a separate operation.  None of this is mentioned.)

Uterine rupture  (0.3% PVD; 0.2% PCD)

*Anaesthetic complications (PCD 5.3%; PVD 2.1%)

Obstetric shock (0.2% PVD; 0.1% PCD)

*Acute renal failure (0.04% PCD; 0.02% PCD)

*Assisted ventilation or intubation (0.1% PCD; 0.05% PVD) 

*Puerperal venous thromboembolism (0.6% PCD; 0.3% PVD)

*major puerperal infection (PCD 6.0%; PVD 2.1%)  You can’t blame an uncomplicated, planned cesarean for puerperal infection.  This is the result of poor infection control, lack of asceptic technique and substandard staff and hospital cleanliness and hygiene.  Many hospitals have zero infection rates for planned cesareans.  A rate of 6.0% is shameful.

*in-hospital wound disruption (PCD 0.09%; PVD 0.5%)  This rate will go up if they aren’t done properly.

*Obstetrical wound hematoma (PCD 13%; 2.7% PVD)  ditto

* Consider how these variables could change if the study period included only data after 2001 with the changes in obstetrical practice I’ve previously mentioned.  This study also looked at planned cesarean deliveries for breech deliveries as representative of all planned elective cesareans but breech cesareans are more difficult than cesareans for cephalic presentations and would reasonably be expected to carry higher maternal risks.

What about the other variables they aren’t mentioning?

Short term and long term health problems

 urinary incontinence, anal incontinence, pelvic prolapses, sexual problems, post traumatic stress, genital tract trauma, subsequent gynaecological surgeries and infections that occur after hospital discharge are examples.  All of these serious morbidity issues are associated far more (or exclusively) with PVD than PCD but they aren’t even mentioned.  No legitimate study ignores important variables.  Study conclusions depend on how you define your study terms.

Maternal experience

How did each individual mother feel about their experiences?  What about the benefits of avoiding anxiety and pain of labour and delivery?  Sedation, tranquilizers, anti-depressants and anti-anxiety pharmaceutical use is part of pregnancy and especially labour and delivery.  How about a reduction in concern about the baby’s health?
It is also worth mentioning that this study ignored the very real problem of doctor and hospital variations.  Including statistics from rogue doctors and substandard hospitals misrepresents the ideal.  The way morbidity was defined in this study would favour higher adverse effects for surgical deliveries than for vaginal deliveries given this reality.

Rule #4    Was the study independent?

 Often medical studies are designed or paid for by pharmaceutical companies, medical device companies or people who would like to keep their jobs.  There are a number of dirty tricks used to hide negative results in such cases.  I don’t think that factored into this study but it is something you should be aware of when you look for bias in other studies.
Many reputable medical journals insist on independent statistical analysis of raw data as a means of reducing bias and maintaining integrity.  This study did not have independent statistical analysis.
Censorship by publishers and editorial staff is another area that limits the integrity of some journals.  Unless these controversies are exposed by someone with integrity and inside information or are picked up by a responsible member of the media these issues never see the light of day, yet they have a profound impact on what appears in medical journals. 
 

As an example, consider the Canadian Medical Association Journal (CMAJ) and its recent struggle with editorial independence. 

On February 20, 2006, Dr. John Hoey and Dr. Anne Marie Todkill, long-standing senior editors of CMAJ, were fired by the publishers – the Canadian Medical Association (CMA).  The CMA had recently decided that their long standing policy of making women come to them for post-coital contraception [levonorgestral or Plan B] violated a woman’s right to reproductive choice because of the barriers they had placed in a woman’s way.  They made Plan B available without prescription.  The CMAJ sent 13 women to buy the emergency contraceptive over-the-counter in pharmacies across Canada, and report their experiences.  The pharmacists asked them for personal data, including the woman’s name, address, date of last menstrual period, when she had unprotected sex, customary method of birth control, and the reason for dispensing the medication.  This was done at the recommendation of the Canadian Pharmacists Association (CPA), which also advised members to store the information permanently on their computers.  Clearly the CPA had their anti-choice barriers in place.  The Canadian Women’s Health Network (bless their hearts) said the obvious by stating that collecting this information was unnecessary and a violation of privacy.  The CPA complained to the CMA, demanding that the names of the pharmacists be removed from the CMAJ article (bullies never like being exposed) and the CMA ordered the CMAJ to comply.  The CMA then fired Hoey and Todkill, stating they wanted to ‘freshen up’ the journal.  The rest of the full time editorial staff resigned on February 28, 2006. 
The former editorial staff at the CMAJ launched a new open-access journal [Open Medicine] in April, 2007.
The CMAJ went on to admit the episode raised serious concerns about the integrity of the journal and its reputation.  Duh. I give them credit for laying the cards on the table and admitting mistakes.  Positive change doesn’t happen without an initial admission of guilt. A warning posted on the CMAJ website by the editorial committee states “In our view, any attempt by the CMA to impose its influence on the editors would be catastrophic for the CMAJ’s reputation as well as damaging to the reputation of the CMA.”  Too little, too late?
Such bad behaviour by the CMA and CPA isn’t restricted to Canada.  Censorship and medical integrity issues are serious problems being addressed (hopefully) around the world.
This cautionary tale highlights the problem of medical solidarity at all costs and it influences what you will see, and just as importantly, what you won’t see in medical journals.

N)  “A labouring woman needs first to be protected against any stimulation of the thinking part of her brain - the neocortex. This part of the brain needs to take a back seat and allow the primal ‘unthinking' part of the brain connected to basic vital functions to take over. A woman needs to be in a world where she doesn't need to think or talk.

This chauvinistic endorsement of trauma induced dissociation is widely quoted by several (but not all) who champion ‘natural’ childbirth.  Statements like this are from that past era where women were encouraged ‘not to worry their pretty heads’.   Being in a world where you are actively encouraged not to think or talk sounds like a setting for some B grade horror movie.  Not thinking is a bizarre strategy to champion for thinking, feeling humans.  I haven’t met a woman yet who wasn’t an intelligent, thinking, feeling type.  My advice to any woman contemplating pregnancy is to put that thinking neocortex into overdrive, not shelve it.  You NEED to think and gather as much information as you can to make an informed decision that is right for you.  It is vital that you think.  Thinking is not a bothersome affliction.  It is not something you should turn off, or accept having turned off, through pain and humiliation induced dissociation or mind altering drugs.

o)  "Epidurals will hurt your baby"

There is no more creepy or insidious (and highly effective) way to manipulate women than to use their maternal love and concern for their child as a weapon against them.  You can force women to accept all manner of horrors if they feel they are doing it for their baby.  That is exactly what this bias is.  Mother love should be respected as the beautiful thing it is and not used as an excuse to hurt mothers.  There is no credible evidence to support this bias.  There has never been any credible evidence to support this bias.  There will never be any credible evidence to support this bias because it is not true.

P)  “No pain, No gain”

Unless you view labour and delivery as an extreme sport – and some do – there is nothing about this bias that serves women well.  Denying effective pain relief to woman during labour, delivery and the post partum without a scientifically valid reason – and there really isn’t any - is misogyny.   Despite this it is still a widely held bias.

Q)

“Vaginal births are safer than planned cesareans” 

“Planned cesareans take longer to recover from than spontaneous vaginal deliveries”

If either of these were true we wouldn’t hear so many stories where the opposite was true.  If either of these were true many obstetricians, anesthesiologists, nurses and others with access to inside information wouldn’t choose a planned cesarean for their own deliveries or those of their loved ones.  If this were true the vast majority of horror stories we hear about wouldn’t be about planned vaginal deliveries.  And if this was true most of the medical malpractice suits filed against obstetricians, midwives and hospitals wouldn’t be about planned vaginal deliveries.

 

R)  “Evolution/Nature wouldn’t make childbirth dangerous.”  

People with this bias have a poor understanding of evolution.  They assume that the end product of evolution is better than the starting point and that maladaptive traits are eliminated as generations go on.  I’m not saying that natural selection isn’t a powerful and effective force.  It certainly is and it isn’t a very pretty process.  Human technology shields us from the full effects of natural selection.  Left to the unchecked processes of natural selection (like getting rid of modern shelter/medicine/optometry/dentistry, etc. ) most of the human population, regardless of gender or age, on earth right now would die, including those with a poor understanding of evolution.  I wouldn’t last very long myself.  Letting natural selection run amok is the last thing a civilized human society would, or should, allow.  But even if we did evolution would not eliminate all maladaptive traits.  It wouldn’t even eliminate all the stuff that doesn’t contribute anything.  Our own human genome is ample evidence of that.  Most of the DNA in each of us is evolutionary baggage.  It doesn’t code for anything yet we replicate the whole shebang every time a cell divides. 

Mutation is a spontaneous process that can occur during cell division/DNA replication.  This can happen during egg or sperm division (meiosis) or during human growth and maintenance that occurs constantly in people of all ages (mitosis).  Cell division is a fascinating, elegant and complex process that is prone to errors, as all complex processes are.  Most mutations are bad or neutral.  Very few give an individual an advantage.  All the positive attitudes about evolution and nature in the world will not stop this. 

Chance – blind, dumb luck or the lack thereof – also influences evolution.  It doesn’t matter if you are the strongest, healthiest person around - if you are covered in a mudslide, drowned in a flash flood, swept up in a tornado, killed in a car accident, whatever, and you haven’t reproduced you obviously aren’t going to be evolutionarily successful.

Consider how many maladaptive traits are carried through from one generation to the next, even though those with the disease generally don’t reproduce.   Cystic fibrosis, hemophilia, muscular dystrophy, colour blindness are but four examples.  There are plenty more.  Consider our evolutionary vestiges.  We have a tail bone but humans don’t have tails.  They would look darned stupid and they would make finding a pair of jeans that fit right even more difficult and we don’t need them.  Our early evolutionary ancestors did and it gave them a survival advantage.  Evolution hasn’t rid us of this or any other trait we no longer use.  A trait will continue in any species as long as enough people have that trait AND it doesn’t kill more individuals than can survive with it.  Put another way, evolution allows certain traits to continue because they don’t reduce fitness enough.  As well, many maladaptive traits aren’t even seen until after reproduction occurs. 

Evolution is measured in the number of reproducing offspring – not lifespan or quality of life.  Evolution doesn’t give a whit about whether the individual likes it.  Consider the lives of two women.  The first was a happy camper who was very rarely sick.  She died at 100, not because she had anything terribly wrong with her.  She was sharp as a whip and still active.  She was hit by a bus because her recent limited mobility didn’t allow her to move out of the way in time.  She never had children.  Another woman dies at 62 of complications from diabetes.  She also had moderate dementia.  Life had been hard for her, as one would expect.  She had two children who both had children.  It is this woman who was evolutionarily successful, not the first.  It is her genes passed to the next generation.

 Evolution will not eliminate any trait that is required for survival in another capacity.  Evolution will never act to reduce the size of the human head because without our increased capacity for intelligence we couldn’t survive.  Evolution will never act to increase the size of the human pelvis because to do so would negate, or seriously limit, our bipedal mobility which would clearly not be advantageous to survival.  Bipedalism requires the legs to be close enough together so the person can walk and this limits the size of the pelvic opening.

 This would be a good time to also consider cultural pressures on evolution.  Two women walk into a bar.  The first is stunningly beautiful.  She is tall and slim with large breasts and a beautiful face.  The other is tall, with moderate sized breasts, a little plump, a beautiful face but her hips are huge.  She has a tough time getting on the bar stool.  Both are wearing the same outfit.  Which one do all the men in the bar want to go home with? 

For those interested in learning more about human birth and evolution there is a book called Human Birth: An Evolutionary Perspective [Wendy R. Trevathan, Aldine Publishers, 1987] that can give more insight. 

 

S)  “Millions of women have given birth vaginally, so you can too.”

Those with this bias never complete that thought process and see the bigger picture.  Certainly millions of women have given birth vaginally and survived.  And millions of them haven’t and many, many more have survived but with negative consequences. 

 

T)  “I had a vaginal birth without drugs/ planned cesarean/ vaginal birth with drugs/ suffered terribly/ etc. and you should too.”

People with this bias have what I like to call Centre of the Universe Syndrome (CUS).  The afflicted suffer from the delusion that, as the centre of the universe, everyone must do and think exactly as they do and think.  Of course, this affliction isn’t concentrated in obstetrics and it certainly doesn’t affect only women.  Recently, at an office, I witnessed two men fighting over the best way to put a cutting board into the dishwasher.  Both insisted their way was the best way and the fists were ready to fly.  A wise and diplomatic co-worker suggested that, at each of their houses, they could put the cutting board in their dishwashers the way they wanted but maybe it would be best today to wash it in the sink.  Three perfectly acceptable ways to get the job done.

Everyone has their own opinions and beliefs.  They are the product of their own experiences.  A person’s fears are a valid part of who they are.  What works for someone doesn’t make it suitable for someone else.  We are the centre of our own universe but we are not the centre of anyone else’s.

U)  “A baby is worth the terrible suffering”

I wonder if people who have this bias think that babies that didn’t result in terrible suffering and maternal injuries aren’t worth it?
