EstRusMum the stats from the Birthplace study were based on intended place of birth, so a birth planned at home remained classed as a home birth even if transferred, for the very reasons you mention.
Chalala - for mums birthing second or subsequent babies, the most severe outcomes were the same (as in death or severe injury or illness) but the less severe outcomes were very significantly improved with home birth or MLU birth. For instance, for planned home births or MLU births, the risk of a CS birth was about halved. Birth using forceps or ventouse, and other birth trauma and physical damage to mothers were significantly less out of hospital.
All this was the same for first time mums too, however, there was a very, very tiny increase in the most serious outcomes to babies which is sometimes described as 2x greater risk of babies dying if birthing at home compared to hospital or MLU (MLU still has same outcome as home). When the Birthplace study was first released this was the DF's headline of choice, rather than all the good stuff - and it wasn't even true.
In fact, it's yet again not that simple. The numbers of babies dying was so immensely tiny that there was no significant difference between those who were born at home or anywhere else. Only by combining those figures with a number of serious outcomes, such as meconium aspiration syndrome and many others, were the numbers made significant - from 5 in 1000 to 9/1000. 13% of these 9 were babies who died either in labour or within a week of birth. So about 8 of these 9 babies will not have died.
Compare some other stats:
Multiparous women:
episiotomy: 15/1000 (home), 23 (MLU), 35 (alongside MLU), 56 (OB unit)
CS birth 7 (home). 8 (MLU). 10 (alongside MLU). 35 (OB unit)
So for NO medical reason women who planned to birth at home EVEN if they ended up birthing in hospital) had a 7/1000 risk of a CS birth compared to a 35/1000 risk in an obstetric unit. That, my friends, is outrageous. Stats for CS birth in nulliparous women are significantly higher as is usually the case, at 80/1000 (home), 69 (MLU), 70 (alongside MLU). 121 (obstetric unit).
80 women in 1000 ended up with a CS birth who had planned to home birth. 121 who planned to vaginally birth in hospital, going in with the same "risk factors" had a CS birth.
That is why the 2x likely your baby will die headlines, and (indeed anything) what the "Sceptical OB" writes about a 4x risk is just meaningless, and does NOT inform us.
Part of any campaign is to increase MW numbers. Homebirth is cheaper than hospital birth - even with two midwives. Properly set up and run, it's cheaper on so many levels.
- Fewer hospital rooms needed, maintenance of which is hugely costly. Cleaning of a room, new sheets, etc, in labour and postnatal covers the cost of the midwife's additional hours with having two at a birth.
- Fewer CS births or instrumental births which are hugely costly
- Lower costs in follow up care of the women who were physically damaged in birth, say by a CS birth or episiotomy, etc.
- Less pressure on psych services due to women feeling more positive about their births when they go well (and more do, I'm talking over a community here)
Just to throw a few out there. There's many more.
