I think NICE really do have to improve this, because women's healthcare is important and not more or less so than other areas. To be honest, if the NHS can't afford things, it needs to address this in different ways rather than pretending that the evidence says something it doesn't because of cost factors. I have seen this time and time again in my own field (am a HCP). Cost factors reduce available choice and over time practitioners begin to believe that what is offered is state-of-the-art against best available evidence.. there can even be a grudging "this is the NHS, take it or leave it" attitude that does no one any favours. If the NHS can't survive as a free-at-the-point-of-care service, that is no reason to deny or ignore evidence: there will be a need to look at different payment models and yes, involving patients in paying for some choices where this is practicable or involving a sliding scale/means-testing for some payment.
However, it is a dangerous game in public health care to place maternity services against, say, cancer care because one is more "worthy". The rate of infant death in late pregnancy and childbirth is very high in this country and despite the report I mentioned earlier (late 1990's) nothing has really changed in a long time. The forums here have been full of really shocking tales of poor treatment and substandard care, and although I feel I was fortunate in that the team dealing with me were skilled, it was definitely a "bare basics" service and at very many points a toss of fate's coin could have really caused even more serious damage to me or ds.
This is what would make me want to consider choosing a CS. Not because I really want one, but because I feel that there would be less likelihood of being left to labour alone or in situations that might risk my health or that of my baby. That's not really a lifestyle choice now, is it? Ideally I would favour decent quality maternity services that would mean a good VB was likely but I know that this is less likely to happen before I next give birth than that a CS would be adequately staffed. It is not right that people are afraid to give birth in a developed country because of fears that they will not be attended to safely in labour.
This isn't really good enough, just because childbirth is a "choice". There is more to humanity than living and dying and our biology, as mammals, is strongly geared to reproduction.. so saying "just live with your choices" is a weak argument. If I lost my partner or my child tomorrow, I would live but would be devastated... if someone told me that I had made my choice by choosing to love someone, knowing there was a risk of pain and death, I would (rightly) want to lamp them.
If your argument is that the NHS is free so like it or lump it, then that seriously undermines the feasibility of that system. It needs to be safe for all, that is a basic determinant of its fitness for purpose.
