This gets at the heart of the issue. The one use for wilderness medicine. So people can tell their buddies, "We can go do crazy stuff in the back-country, get seriously injured, not have access to modern transportation, and still be fine because...I know wilderness medicine." Complete lunacy.
It would be a great skill to be able to do an appendectomy in the field, but the chances of that being needed are astronomically low. Besides, if you want to learn how to reduce a shoulder, you work in an ER, you don't go to a wilderness medicine course.
If you want to learn medicine, you go to where the practice of medicine is happening, not to the wilderness to literally practice on fake patients and run through scenarios that could possibly happen.
The only examples of things that would be helpful to patients in the wilderness are either things that would be taught to any paramedic, or they are things that would be taught to any ER resident.
There's a lot of back and forth going on, and i'm honestly not sure why. I think that everyone would agree that skills specific to "wilderness" or "international/developing world" medicine are not things you generally need in your every-day practice in the ED. But they ARE legitimate skills - not only for practical purposes, but also to give you a better understanding of where you're working and what you're dealing with. Some personal examples:
I spent a month in the Himalayas with a group called the Himalayan Health Exchange. We spent a month trekking in Jammu-Kashmir (northern border of India), setting up clinics for local villages as we went along. 95% of what we did was incredibly routine and only mildly educational - scabies, vitamin deficiency, pterygium, etc. Not too exciting, although I did see some fantastic clinical findings that I definitely haven't seen in the US. But we also had several cases of altitude sickness (where one guy got pulmonary edema and had to be evacuated out), drained several abscesses (had to sterilize a blade in the field), and learned a lot about the chronic effects of living at altitude (physiology, etc). Not to mention some down-and-dirty dentistry! This group is also affiliated with HRA (Himalayan Rescue Association), which runs clinics on some of the major trails leading up to Everest. Physicians volunteer up there for 2-3 months at a time and aside from treating climbers for sprains, infections, HAPE, etc., they also treat a lot of the locals.
What is all of this useful for? Well, nothing if you're just going to practice in an ED somewhere. But if you want to work on expeditions, or work in Nepal or any developing-world location at high altitude, or even just climb, it's extremely useful to have this exposure. There's also a ton of critical care research going on at Everest. If nothing else, it was a month that opened my eyes to some very "out of the box" possibilities and things I can do with my career later on.
I think that programs with a specific focus - EMS, wilderness, international, etc., are not just valuable for the skills they offer but for the exposure to opportunities outside the beaten path. How else do you learn that you love diving medicine and want to go work with Navy divers if you haven't spent time in Hyperbarics? How do you even find out about Himalayan health posts if you don't have the opportunity to go and work there? I've met several US EM docs doing incredible things - setting up an emergency clinic in Rwanda, working with the IRC, disaster relief during the Tsunami and later in Pakistan, volunteering with MSF, working in South Africa, Zimbabwe, Australia... and so on. The opportunities are endless, IF you make the right connections - that's where the "wilderness medicine focus" question comes in, and that's why it's incredibly relevant for those that are interested in it.
Even if you only spend 5% of your time doing things that directly involve these niche areas, it's amazing. It's what keeps many people going. And I don't understand why those who aren't interested in them are getting so worked up about it.
