Thoughts about what my sister in-law thinks when a midwife calls EMS.

My wife (EMT) was telling me (paramedic) that her sister who is going to become a midwife how they just call EMS for a ride to the hospital from birthing center in emergency and they (midwife) are the ones who are in charge of all pt care. SIL also said that they get upset when EMS asks all the question like if a BGL was checked (yes that was one that the lady she was shadowing was pissed that EMS asked) and thinks it's irrelevant to asks the questions we are trained to ask. That same call the medic told the midwife to calm down and need to anwser the questions. SIL did admit to my wife the midwife was a little frazzled due to the severity. When my wife told me about that I said if they called me it's my pt and I may let them assist me if they seem competent and would be a good recourse. If they aren't then I wouldn't let them either go or sit in the back. Yes I would like use them for information or extra hands if needed but not if I feel they would make the situation worse. My SIL is in the twin cities area and wonder if anyone is there and what you do or anyone anywhere how you deal with midwife and what is your policy with them. Like I said I feel that they called me so it's 100% my pt and would be like hand-off for a IFT. We live in an area that does not have many midwifes so I haven't had to deal with them. My wife did make a comment to her that if they think that then why don't they just get a van for the birthing center after she pretty much said they are higher level of care of a paramedic and just using EMS as a taxi. I'm not trying to bad mouth midwife but trying to understand if someone would give full control of their rig to someone else.
