According to this single study.

From a personal point of view, I would ask myself: does waiting for an ambulance to arrive and then get to hospital increase risk to mother or child when a sudden complication arises? Bearing in mind that if the midwife could cope with the complication, the ambulance would probably not have been called.

I would choose to already be in the place where the specialist teams and equipment are.

We're still talking about general odds here. None of which are satisfactorily granular for me.

There were complications when dalglia was born. Suddenly. He could have died or been permanently mentally disabled. Fortunately, we were already in the NRIE and within seconds a medical team was in the room. They acted like poetry in motion, like they were telepathically linked. Stuff happened. And dalglia was delivered safely.

Would I want to have waited for an ambulance? No. dalglia could have died. Would I want to have waited for the ambulance to reach the NRIE from the wrong side of the city? No. dalglia could have died.

I realise this experience may skew my opinion but: fuck that study.

Forget the statistics for a moment: can adding 30 minutes of delay to treatment of an ongoing life threatening situation increase the risk of death? Let's say... ::shakes magic 8-ball of deadly childbirth complications::...massive bleed out from mother after birth due to tearing.

If we're going anecdotal, my son nearly died due to complications caused and worsened by hospital procedures and conditions. For one thing, the hospital had no air conditioning or hot water - I'm not kidding! I had both at home.

Then they saved him, then he had an 8 minute seizure. He's only marginally impaired.

I was very tempted to have my second baby at home, but lived more than an hour from hospital so decided it wasn't prudent. He was born with no doctor in the room because I had him so fast they didn't have time to get there from down the hall.

In light of my experience, I absolutely believe that, in the case of a healthy woman who has been screened for complications and attended by a midwife, home within reasonable range of a hospital is just as safe as hospital.

Apparently there's a saying going around Microsoft now; bowdlerized, it's, "the average person has one breast and one testicle." It's a caution against relying on statistical models without examining the context.

I strongly suspect that the reason second-child home-births have the same complication rate as hospital births is that those who were most prone to complications (as demonstrated the first time) went to the hospital. This skews the result heavily... indeed, I'm surprised that home-birth for second children doesn't show a greater safety rate because of that bias.

Of course I haven't seen the study design or how they controlled for this so perhaps I'm being unfair.

Because complications are rare, pulling complications out of the home birth pool is like pulling tokens out of a bag with a lot of tokens. So removing the mothers who had complications the first time shouldn't affect the home birth statistics positively enough to detect. Which is just what we observe: home births rise to the safety level of hospital births on and after second birth, but do not exceed it, despite the theoretical skew from first-birth complications electing hospital the second time around.

Edit: the study is talking about comparable risk of complications occuring between different birth settings for the second birth but doesn't cover what happened when there were complications.

So, the risk of complication is roughly equal between birth settings for the second birth, but: where there were complications, was there an increased risk to the health/well being of mother and child being away from hospital?

At the risk of sounding flippant: a statistically insignificant outcome can feel pretty damn scary and significant when your result is one of the outlying exceptions to the rule.

Dalglivk did an obs and gynae attachment at St Johns and saw the fallout of enough outcomes, that would have been statistically insignificant for this study, to convince her that hospital was best for her births.

I'm with danieldwilliam: I'd want to be where all the surgeons hang out.

Actually, I thought the GMC had given guidance that everyone can drink as long as they do it in moderation. Sadly, the general drinking populace are generally incapable of understanding 'in moderation' and come up with things like 'alcopops don't count' etc. So it's easier for government to say 'don't drink at all'. Of course, government also has an agenda to reduce NHS costs which are hammered by heavy drinking related illness and injury every Friday and Saturday night...

I correct 'general drinking populace' to 'loud cohort who make people's lives a misery on a Saturday night'.

And agreed re GMC. The problem here is that some members have a political and ambition agenda that they can only further by spouting heavy handed garbage.

The anecdote is to illustrate that even with statistics on your side, shit still happens.

In that scenario, where would you rather your wife and child be?

I not sure that question is a fair comparison. They do not carry like for like possibilities of 'complications'.

Now: if i lived in a 200 window building and I knew that a rogue police marksman was aiming at a random window and was going to shoot whoever opened it, would I open my window? Probably not. I'd find a less risky way of getting fresh air.

Let's see how far we can take this analogy :)

Let's say risk of 'complication' from rogue police sniper is 1% in an apartment block 45 minutes from the hospital and a hospital block being terrorised by another rogue police sniper.

What the statistics of the study say is that, for people who have already been shot by a rogue police sniper once before ~45% of the unlucky 1% who get shot back at the apartment block end up have to go to hospital anyway (albeit mostly for flesh wounds). Critically, the statistics say that the risk of dying from being shot by a rogue police sniper the second time around is the same whether your at the apartment block (a 45 minute ambulance journey from the hospital) or at the hospital block (where all the surgeons are).

You know what? I'd still rather be shot by a rogue police sniper at the hospital block.

Reading more on this. It's quite fascinating seeing the different studies from different groups with different agendas.

Of course a statistically insignificant outcome feels more important when you're in the middle of it.

This is why anecdotes make for awful recommendations
