Under Michigan protocols, the only way a pt can be 'handed off' or pt care transferred, is to someone of equal or higher licensure. Since a medic made first pt contatct, they cannot legally transfer the care of a pt they deem as a BLS pt to an EMT-I or EMT-B. They will have to transport the pt themselves, and notify dispatch that they are transporting BLS. RUQ pain, fetal postioning ... lack of masses does sound like Cholecystitis. Granted the call MAY be a BLS call, but the medics in this case would be considered negligent under Michigan protocols, and could in fact be facing abandonment charges because they did not follow protocols in the proper transferrence of pt care.
