Health, there is a high corrolation between elderly in hospitals or long term care facilities developing increased colonization of c. diff, causing extreme diahrea and often death. But feel free to say I am blaming this on medical negligence.
Lets face it – hospitals are places where sick people go. My OBGYN encouraged me to use a local, community hospital during pregnancy for non-extreme emeregencies. She said that if I would come in to Columbia, I would be exposed to a lot more lethal diseases when all I needed was an IV and antibiotics.
Hospitals are not these sterile zones we think of them. There are sick people there. Your home is generally safer.
That being said, I will most likely end up with a (hopefully medical intervention free) birth in a hospital. With my OBGYN, who respects my wishes to be as intervention free as possible.
