Your friend has my sympathy and prayers. Regarding this horrible tragedy, I would recommend that she sit down with close friends and family and make a list of what she wants the hospital to do. At a minimum, I would suggest including at least six consoling sessions, that the hospital develop a new fool-proof internal procedure for dealing with miscarriages like this one, and universal annual training in this procedure for all hospital personal. Once she has a list put together, she will need to pay a widely feared attorney for a half-hour to draft a letter demanding these items using the threat of a large monetary lawsuit.
I'm amazed at the number of FReepers in this thread who think that hospitals are intimidated by lawsuits. Lawsuits, and lots of them are just part of the day to day operation of any hospital. This hospital probably has at the very least a dozen going on right now where someone actually died as the alleged result of someone's actions. I hate to break this to you guys, but an incident like this would be handed down to junior members of the legal team to settle or litigate.
