I think that privacy is always a primary issue and the BBC nor any of the other people (besides the parents) are not really at liberty to discuss what it was that happened, because that would violate the parent's right to privacy. While I do not know the story, a poor outcome likely means that a baby was born still, which happens. It is always a tragedy and always worth looking into to make sure it was not something that could have been avoided.
I think the BBC is a very safe and reasonable place to give birth and I have atteneded becautiful births there myself. If you are a patient of those midiwves, you might be able to ask for further reassurance or explanation from them.
Faeriecurls, congrats on your pregnancy!
