@DrParasite said medic really isn't going to help you get into nursing or PA school, or med school for that matter. Most health professionals that don't work in EMS or EM dont usually know or care what the difference between the role of an EMT and a Paramedic, including those who are involved in the admissions process for these programs. They will like that you have some experience in healthcare and that you have the desire to build on you education, so there is value in EMT experience.
If you want to be advanced practice I would recommend PA over NP. PA programs are designed to take candidates with minimal healthcare experience and make them effective in their role in 3 years. NP programs are less intense because they rely on nurses' prior experience at the bedside and their prior BSN education.
Dont be fooled by any of those direct entry NP programs, they are not making good NPs and their graduates have a harder time finding jobs than their peers who had bedside RN experience.
Personally I also think that anyone who wants to be an NP should have been an good RN who enjoyed taking care of patients. APRNs are still nurses, those who go advanced practice and dont take pride in the basics of being a good nurse should have found some other kind of work.
Personally I dont see a lot of value in community paramedic as a concept in the United States, and I doubt it will build in any substantial way. The services that are similar in other countries are provided here by community health nurses, who are also paid more so all the community paramedics end up being in many cases is cheaper labor. Whether a paramedic or nurse visits a purposefully noncompliant DM, COPD, CHF, ESRD, or whatever else doesn't change that pattern of health behavior. Those who abuse the 911 system will still do so even if a medic visits them once in a while.
