Along the same lines, I give out mortin 800s all day long. After I have assessed a patient and decided on a treatment plan.
That assessment does not require a host of adjuncts like labs and xrays all the time, but it does require knowledge and responsibility.
Sorry, but most of the US EMS providers are simply not capable of safely deciding a patient doesn't need a hospital or can make due with an OTC.
In other countries that require more education it is not an issue. In countries where the provider signs the chart and is held accountable to those decisions without pointing the finger at the doctor when something goes wrong, that is not an issue.
But the US is the most simplistic of protocol medicine in EMS. It is one size fits nearly all with just a few sizes in stock.
It would benefit not only the patients, but the economics for US providers to be at the same level as their counterparts in other modern nations.
But it is not a popular view on EMTlife, in the real world even less.
