My midwife failed me: How homebirth transfer affects mothers

Homebirths account for just a small percentage of all births in the US: 0.59% of births happen at home. Interestingly, this number increased by 5% between 1990 and 2005, which we could call a surge in homebirths [1]!

Besides homebirths being more satisfying for women [7], one of the main reasons some women choose a planned homebirth over a hospital-based delivery is because both mothers and babies have better outcomes. The cesarean section rate in homebirths is around 4%, compared to over 30% nationwide [4]. Mothers have fewer interventions, including episiotomy (a surgical cut to open the vagina), and babies die less often [2].

There is no way to sugar-coat that. Babies born at home die less often -- because of the lack of unnecessary interventions. One meta-analysis found that the neonatal mortality rate tripled in planned homebirths versus hospital births, and attributed the better outcomes for babies to the decrease in interventions [2].

Not all mothers that plan to deliver at home end up doing so. For a variety of reasons, a transfer to a hospital may be necessary or preferable during or after childbirth. Sometimes the reason for transfer is maternal exhaustion -- labor takes a very long time and the mother is too tired to go on. Sometimes there are negative health signs with the baby -- heart rate decelerations, or meconium in the amniotic fluid. Rarely, the transfer is caused by something more grave. Usually, the decision to transfer from the home to the hospital rests on the midwife. In the US, the transfer rate is around 12.1% [4].

But how does a woman, who planned to deliver at home, who spent months preparing for her natural birth within the safety and comfort of her home, who anticipated an intimate experience, feel about a transfer to a hospital? Anecdotal evidence hints that something is missing from the birth experience. Does the mother blame herself for failing to deliver a baby at home? Does the blame later shift to her midwife, for letting her down? Is she grateful for being able to spend even part of her labor at home [6]?

We turn to science for an answer.

Is homebirth transfer traumatic?

Let's take a look at the Netherlands, where the homebirth rate is much higher than the US: In one study, over 38% of first-time moms and 67% of repeat mothers delivered at home (recall that the US average has risen to under 1%) [3]. For the first-time moms, 40% of the planned homebirths ended up transferring to the hospital at some point during birth or shortly thereafter; and 11% of repeat moms transferred to the hospital (compared to 12.1% of home-birthing mothers in the US, both first-time and otherwise). The Netherlands data is summarized in the table below.

Repeat mother
Planned homebirth
38%
67%
Transfer to hospital
40%
11%
The women in this study rated their birth experience, their midwife, and their immediate postpartum days by marking agreement with specific adjectives on a five-point scale (where 1 is strongly agree and 5 is strongly disagree). The conclusion from this study?

Our research showed, contrary to expectations, that an unplanned transfer from a planned home birth to hospital has little influence on the experience of childbirth [3].

Let's look at Sweden.

In Sweden, homebirths are rare -- as rare as in the US -- that is, less than 0.1%.  In Lindgren, et al.'s study [5], the homebirth transfer rate was 25% for first-time mothers -- that is, one in four women that plan a homebirth end up in the hospital (much better than the 40% rate in the Netherlands). The most common reasons women transfer to the hospital are "lack of progress" and (this was surprising to me) the midwife being unavailable for the mother during labor.

The exciting conclusion in Sweden:
Being transferred during a planned home birth negatively affects the birth experience [5].
Looking elsewhere, we find agreement:
Women who are referred to the hospital while planning for a home birth are less satisfied than women who planned to give birth in hospital and did. A referral has a greater negative impact on satisfaction for Dutch women [than for Belgian women] [7].
In fact, the Swedish study found that women really hated and resented their homebirth transfer experiences, as visualized (by me, from Lindgren's data) by the graphs shown below in Figure 1 and Figure 2.  In these graphs, the blue line indicates a "very satisfied" response and the red line is anything less than "very satisfied." The thing to take away from these graphs is the area inside the red line. A large red area is bad. In the homebirth without transfer case, you can see that women were more likely to be "very satisfied" with all aspects of their birth (except for being in control -- but can you really control birth?).  In the homebirth transfer case, women were more likely to be less than satisfied with everything except partner support and the midwife making the partner involved.

Figure 2. Satisfaction among Swedish women that planned a homebirth but transferred to the hospital during or as a consequence of childbirth [5].



Homebirth: Forbidden fruit


Could it be, then, that in places where homebirth is rare, women place undue emphasis on the location of birth? Could it be that birthing at home becomes kind of a holy grail that women strive for?  It is so rare in the US and Sweden that it is like a forbidden fruit. We hear and read so much about its beauty that we -- that is, those women that yearn for homebirth -- strive for it and are crushed when we do not get it.

Consider another birth outcome some women consider traumatic: the cesarean section. One thing that childbirth educators did to make the prevalence of the c-section more palatable and less scary is to demystify it. In childbirth education classes, c-section is presented as a possible birth outcome -- a real possibility. In a good prenatal education class, analgesia, surgical procedures, and postpartum recovery will be discussed in detail. When you think about it, this is a really good idea, because one in three people in the classroom will have this surgery, whether or not they planned for it.

It may be that one of the things that makes homebirth transfer an emotionally crushing outcome is that it is still an unknown evil. So why not demystify the homebirth transfer? Describe it in detail for women and their birth partners to take in: causes, procedures, outcomes. The Wiegers study made this interesting note:
It seems more important ... to reduce the fear of unplanned [homebirth to hospital] transfer, especially among nulliparas, than to advise women to choose a hospital birth in order to avoid such transfer [3].
Interesting because this is the only study that I found that did not result in negative emotions in the mothers resulting from homebirth transfer. Maybe in the Netherlands they drill the transfer as much as we (ought to) drill the c-section?

Lindgren had a different conclusion:
Treatments as well as organizational factors are considered to be obstacles for a positive birth experience when transfer is needed. Established links between the home birth setting and the hospital might enhance the opportunity for a positive birth experience irrespective of where the birth is completed [5].
In fact, in the Sweden study, one of the main reasons women were unhappy with the hospital setting was because everyone was so dang mean to them -- possibly for choosing a homebirth to begin with. They found that doctors -- obstetricians, general practice physicians -- simply do not understand what a midwife does in the home and why she should continue to be useful even after a transfer. Maybe the homebirth transfer education should start with the hospital.

Did my midwife fail me?

I do not know. But I do know that everywhere around the world where homebirth is rare, homebirth transfer to a hospital carries with it a negative weight. In the Sweden study, half of the women that underwent homebirth transfer were less than satisfied with their midwife's support, compared to over three-fourths (76%) of those that stayed home. Not surprising when you consider that the #2 reason for transfer is because the midwife simply could not come to the birth [5].

Conclusion

There are three ways to fix the problem of the negative affect of homebirth transfer.

  1. Teach hospital staff about homebirth transfers. Drill it, demystify it. Emphasize that a transfer is not the mother's fault; it is not the midwife's fault. These things just happen.
  2. Teach mothers that plan for homebirth about homebirth transfer. I mean, really drill it.  It is a real possibility and a mother should know the routine. Drill it, demystify it. Encourage that a transfer is not her fault.
  3. Encourage homebirths. There is reason to believe that, when the overall percentage of women that plan for a homebirth is large, a transfer to the hospital is no big deal -- possibly because the hospital staff know what to expect from a woman and her support team, and how to best help.

Given our surge in national homebirth rates (still under 1%, but we do our best), you would think we would be quick to implement these items.

  1. Interesting, thank you. I am still trying to figure out why I have regret about my transfer to the hospital for the birth of my second. She was a successful VBAC baby and I thought that was my goal by selecting a homebirth in the first place. Why do I feel so negative about having to transfer when ultimately, she was born naturally? I think you hit the nail on the head - a homebirth to me was described as this transcendent, beautiful and sacred event and since she is my last baby, I will never have that. But her birth was a triumph for me nonetheless - I got to 9cm at home and was back home 24 hours after her birth. You failed to mention one thing too - I had to pay for the birth twice - $3500 for the midwives and another $3500 for the hospital.

  2. Thank you for this interesting article. I don't know why the US is so backwards. I wish I was home delivered, then maybe my mother wouldn't have needed a c-section. Or I wish at least she was conscious. Then I also might not have had my penis mutilated but a cutting man. I don't know why the US is so backwards, home births and midwives seem so obvious to me. To go with nature not fight nature. It seems like the cost is just so high, when it comes to health, bonding, etc. I try not to be too "philosophical" or ideological. Nothing against hospitals themselves, but everything against hospitals in America where every woman is on the drip and 1/3 get c-sections. That's just wrong. crazy crazy crazy. They treat mothers and infants like they are objects, not people. Crazy crazy crazy

  3. It seems you are interpreting the data incorrectly for your second article cited. A higher neonatal morality rate actually indicates more deaths, so the article is actually stating that there are triple the number of neonatal deaths in home births vs. hospital births. Below is a link explaining the NMR measure:

  4. Word for word, this is what the article you cited states:

    "Although planned home and hospital births exhibited similar perinatal mortality rates, planned home births were associated with significantly elevated neonatal mortality rates."

    "Less medical intervention during planned home birth is associated with a tripling of the neonatal mortality rate."

    That means that the baby is three times more likely to die at home than at the hospital.

    I'm planning on having a home birth myself, but I don't appreciate other advocates of home birth being dishonest. Articles such as this one make the entire movement seem less credible. From everything I've read, no, home birth is not safer for the baby, European studies indicating its comparable safety are only relevant if the mother and midwife are willing to transfer for the same reasons that mother and baby were transferred to the hospital during those studies, and home birth is safer for the mother.

    My conclusion was this: only when you're low-risk, close to a hospital, and keep a close eye on the baby and mother's state of health during labor, do you mitigate the increased risk to the baby enough to enjoy the benefits of a more peaceful, comfortable, and safe setting for you. Since the maternal mortality rate is so much lower than the neonatal mortality rate, I'd still transfer to a hospital if my baby seemed unwell. I've also had to mentally prepare myself for the possibility of transferring to the hospital for malpresentation, being past due, developing high blood pressure or a fever, etc., because these were the reasons why women transferred to hospitals in the European studies. I'm well aware of the fact that I have the constitutional right to refuse a c-section at a hospital if I feel it's unnecessary. Knowing that I'd transfer to hospital care in these situations has made me even more diligent about having good pregnancy habits such as frequent walking, sleeping well, and maintaining good nutrition. These things can often prevent the reasons a woman has to transfer.
