where I work FT we have 3 crews during the week, and we are 45 minutes away from closest backup (4 medic trucks) and 75 miles from heavy response backup.. 25 minutes from 1 helicopter if they are available and 35-60 minutes from more helicopters.
PT job is 2 to 3 ambulances (4 if a lot of PT are signed up), 60 miles from 1 BLS truck for backup and 110-125 miles from more backup. 45-75 minutes for helicopters.
Fun thoughts for mass casualty
yeah, and? I don't know of a single EMS agency that can justify 20 staffed ambulances standing by just in case an MCI happens.
3 crews during the week sounds appropriate for any given area, depending on call volume. 2-3 sounds good to. I used to work in a city that had 1 ambulance staffed and that's it. you have between 2 and 3 times as much as them. And they relied on mutual aid for a large amount of their routine calls.
The important thing is not to think about how many resources you have at any given time, but rather to develop a plan for what to do if the MCI happens. If you have 1 ambulance, and you have an MCI with 30 patients (two school buses collide head on, building collapse, CO poisoning at the mall or local walmart, or an active shooter with multiple people down), what will your plan be? it's much easier to know in advance where you can get additional resources, vs trying to figure it out when the incident is unfolding.
Using your examples, what you might say is in the event of an MCI, immediately request 2 medic trucks from 45 minute away, and initiate a response from your "heavy response" backup. It might take them two hours to get there, but at least you will have resources available, either for the MCI or to cover the routine issues. You might also initiate an off duty recall, asking anyone who is available to respond to your station and staff a reserve ambulance. You might also request a bus from the local school, or bus company, and use that to transport your green patients, and maybe even some yellows if needed. And do you have the approvals already obtained from the bus companies, from the AHJ to pay OT, and from your neighbors that in the event of an MCI, this is what you are going to request, and they will do their best to commit if available?
Does your state or county have any special resources? lets start them sooner than later. Do you know the
Utah MCI Plan? Does your county have one? if not, maybe it's time to think about one. What about the hospitals? how many can they handle during an MCI? can they recall additional staff, or bring staff down from the floors to the ER to handle the surge of patients? how does that affect your transport decisions?
All these things take planning, approvals, and advance knowledge of what your areas resources are capable of. It doesn't matter how short staffed you are: you need to plan for the worst case, so when it happens, you aren't scrambling to come up with a solution on the fly. And hopefully, you never need to implement it, but if you do, it's nice to know that someone was thinking ahead.
