Ahh, but Penguin - seatbelts can cause horrible injuries - severe bruising at best. Fractures ribs/sternum, ruptured liver/spleen, gut injuries..... Again, not a common occurrence but by wearing one for the small chance of saving your life, you put yourself at risk of some pretty horrible stuff too...... But they do save lives, if not injuries.
Having re-read some of Merkin's posts - good papers. As I said though, those cat 1 sections where only 66% had baby out in the aimed for 30mins cover a whole heap of clinical situations. They will range from the cord prolapse (category 1/2, if you like) to the 'trace was shit but now with some fluid and better positioning it's recovered and staying fine' scenario (category 1.5 perhaps). They all get recorded at cat 1 with no qualification, unless you read the individual case notes. Also, as was notes in one of the papers, rushing unnecessarily can actually do more harm than good (as with many things in life). That's when clinical experience and judgement come in. When we need to rush, boy do we rush. If it's clinically appropriate to back off the gas a bit, then that too. Remember, categories are made, ascribed things used as audit tools. Not predetermined givens. A cat 2 can also become a cat 1.....Most 'emergency' sections are category 2, where decision to delivery is aimed at an hour. Category 3 is within 24 hours so again you can imagine the huge variety of a cases that get shoehorned into those wildly different categories.
Being able to read the papers and look at the numbers but also apply clinical knowledge to bare figures probably makes a difference. You can't really take one without the other, although I'm not sure if it's a blessing or a curse in my current state! If I only relied on what I'd seen, then I'd be convinced that no one delivers except in screaming agony (epidural), with an induction of a section or a tear. Now clearly that's not the case, but I have only seen 1 natural delivery (and that's cos I asked to as I felt I needed a bit of balance!). I'm not going to base all my views on childbirth on my own experience, it's waaaaay skewed.
The homebirth numbers are so very small in this country, and not representative of the population (low risk) that comparing them with hospital births is very difficult. Ditto MLUs. Less of a dichotomy but still there in both numbers and caseload. The fact that about half of 'home births' end up not being also skews things. If about half of hospital births ended up being sent home for delivery, what would that do to figures? Homebirthers are a pretty select bunch; low risk, not wanting intervention and successful, by definition, at birthing at home. Usually, if something goes wrong, they come in. And the complications/interventions happen in hospital.
As somebody earlier said: 'it's just maths'. Yes, it is. But it assumes equal populations and the populations are anything but.
