That's nothing new. Sometimes the system gets overloaded and EMSA has to rely on outside agencies for assistance. Nothing wrong with that. Fire departments do that all of the time. During the ice storm, EMSA was really short on units and was looking for other EMS services to actually post in Tulsa and run emergency calls for them. Someone will get mad about that statement though. They shouldn't, because it was a severe weather event of record proportions and EMSA was running a record number of calls. They were also experiencing a severe misuse of the EMS system. People needing rides to doctors appointments because they were afraid to get out on the ice...etc..etc.
What's WRONG is to ask for mutual aid then try to hide the fact that you did it, and then get mad about it when people mention it. People need to ask themselves: Why would EMSA want to hide the fact that they got overloaded from the public?
I don't think that it will play a role on whether or not TFD takes over EMS services in the Tulsa metro area. Why should it? Again, it's nothing new and it's been going on for years.
As far as the non-interoperability goes, that's not something proprietary to just EMSA. All sorts of agencies around here can't talk to each other. My local fire department can't even talk to the neighboring department that does 90% of the mutual aid in our area. Why? They won't turn loose of any portables. Oh, it's not that they don't have any to spare or anything like that though.
If EMSA had other EMS services running calls for them, they could have easily sent a little EMSA SUV, pickup truck, or van, that you see running all over town to take the other crew some portables while they were helping out. However, the cell phone method seemed to work just fine since there was no interuption of the local cellular system.
