A lot of medical RP comes down to injury and who is involved in the roleplay situation on both sides. Some of my favorite scenes from a medic perspective were when there were extreme injuries that had to be treated multiple times. On these bigger scenes, I would ride in the back of an ambulance and provide medical RP (in terms of the ambulance itself) all the way to the hospital while an EMT was transporting. This was a way for me to show EMT's and Paramedics that there was not a limit to medical RP. I understand the thing with stabilize but it (at the moment) is a command that lets you stay alive. From that point, I don't see any issue with letting some form of treatment fail, especially if you are prepared with realistic injuries. In terms of making the script not protect the medics' RP, -1. Especially for the super injured, the length of time and creativity would cause issues in providing the best treatment and making it fun for the parties on both sides.
Who knows, if medical RP overnight changes for the much better, maybe staff would consider a change.
