I recently talked to a person who writes protocols for my state. The subject of WEMS was brought up, including field C-Spine clearance. State protocols do not endorse field C-Spine clearance. The W-EMT course is not able to replace state protocols. The W-EMT course is also not able to be used as an official endorsement along the lines of "Monitoring-Basic, Airway-Basic, etc." Some EMTs who had taken a W-EMT course were under the impression that they could use W-EMT protocols on SAR calls, as their medical director "took responsibility and cleared the endorsement." This was also not correct.
While the medical director could send an official request for exemption or implementation to have the W-EMTs protocols put in place, it would understandably have to have valid, quantifiable evidence to prove its worth and soundness of practice. This has not happened.
It was therefore concluded that using these "protocols" was not within the scope of practice, and therefore not good medicine.
Giving that it came from the man who creates the protocols for the BOME, I'm willing to say that it is accurate for my state.
Now, with that said, is the W-EMT useless? No, certainly not. It stresses ingenuity and self-reliance. If I was with my family and we got hurt way out in a wilderness area, without roads nearby, without cell or radio service, and without contact, do you think that I'd use what I'd learned? Of course I would. I just wouldn't use it when I'm on a job or when there are better, more proven methods.
Good subject anyhow. Hope I made a helpful contribution!
Take care.
