Don't worry the world hasn't ended yet but there are paramedics in my neck of the woods that suture wounds and prescribe anti-biotics.
Given the appropriate level of training anything is possible and their role is to remove pressure from the already overstretched emergency room. Why remove a doctor from the ED floor to suture basic lacs when it can all be done at home?
Extended care paramedics (ECP's) take on a role similar to a nurse practitioner and are able to keep a lot of sick patients out of the ED. In turn freeing up resources and allowing patients to stay at home.
As for increasing the scope of ALL paramedics to cover these things, that is another matter.
