I poked around some more on PRNMED, & found two people on a survivalist forum who have done the course. One loved it. The other was unimpressed, saying EMT training would be better. I'm thinking that if I'm going to do EMT, I probably won't do PRNMED's course. Also, looking at their curriculum, they really do seem to squeeze a lot into the weekend. I spent quite some time practicing improvising splints in the WFR course, and I got better as a result of all that practice. I'm guessing you can't make the course shorter without losing something.
Interesting.
I have never heard of PRNMED so I googled it. I looked at their curriculum and application. My impression, based on that, is that they seem to cram a lot of rather advanced stuff into a short course. That might be OK for students coming in with previous background such as WFR or EMT. But they don't seem to have any prerequisites, and I'm a bit skeptical they could do a good job of covering all that advanced material with students who are coming in cold.
Having done both WFR and EMT basic, my opinion is that if I could only do one, it would be WFR. EMT covers a lot of stuff related to ambulance work that won't be so useful if you aren't working in that setting. One thing you might get in EMT is a bit more emphasis on medical issues like cardiac, COPD, acute abdomen, etc. WFR covers that stuff as well, but tends to focus more on trauma. EMT tends to assume you have all the toys available and will rapidly transport to an ER, but doesn't much cover working in an austere or improvised environment, or a long term care setting. At least that was my experience. Like I said, I think most folks on this forum would find WFR more suited to their needs.
One thing to check into is your states licensing/certification regulations for EMT. In Alaska, anyone can be certified as an EMT-1 (same as EMT-B in most states). You cannot be certified in Alaska at higher levels (EMT-2, EMT-3, Paramedic) unless you are working in a service (ambulance, VFD, etc) with a supervising physician. In some states I believe you must be part of an official service even to be an EMT-B. WFR is not an officilly recognized certification by the State of Alaska. This is changing somewhat, however. I have been able to count my WFR recert course as CE for my EMT-1 recert. That brings up another point. You might want to ask the PRNMED folks how they handle refresher training.
Medical skills are perishable. To keep my WFR and EMT-1 cards current, I have to do recerts every couple of years. I think even WFA now has recert requirements to keep current.
