In a matter of knowing whether or not emergency medicine is the type of environment you would like to work in, it is helpful, but not indespensable. Extensive physician shadowing and even observation ride-alongs on a paramedic ambulance should help you realize the reality vs. the tv portrayal.
On the other hand, I myself am a paramedic and have been in EMS for the past six years. Through this, I not only have a realistic expectation of what EM will entail, but I think I have the advantage of having something "to hang my hat on" while I am sludging my way through school. I get to practice ALS skills in the field that I am not yet allowed to do in the hospitals (IV skills, drug admin, adult and pedi intubation (incl. RSI), surgical airways, thoracotomy, pericardiocentesis, etc.). This keeps me interested in school and other clinical rotations because I have previous experiences to apply it all to, and I can apply that combined knowledge set into my future pt contacts. This helps me stay motivated.
In this way, EMS would be a great benefit even as a volunteer EMT-Basic(especially in a higher call volume system), just as well as working as an ER tech or CNA in an ED would help you. In EMS, I have been able to develop professional and personal relationships with many of the doc's in my area hospitals. And they are more than helpful in supporting my education in any way that I need- shadowing, tutoring, Saturday night stress-relief drinking parties... 🙂
The EMT-Basic training is rather simple to obtain. It is 120 hrs of course work, usually 2-3 evenings per week and a Sat or two per month for about 6-8 months depending on the school you choose. My EMT-B was $600, but the going rate in my area is now about $850. EMT-Intermediate (IV, intubation w/o RSI, dual-lumen airways, front-line resusc. drugs) is typically another 3 months (80-100 hrs) and $800-1000, and is the same certificate-program format as the EMT-B with a not-so-easy national registry test to complete it.
I got my EMT-Paramedic through an associates degree program, which is nice because all of the classes transferred to my pre-med major. However, most Paramedic courses are still 9-12 month certificate courses that cost $8000-10,000. During the professional year, my program was 700 hrs of didactic coursework, plus just over 1000 hrs of clinical rotations including 24 24-hr preceptorship shifts on the ambulance providing the full scope of practice under the supervision of an assigned paramedic. Keep in mind that even if you do a certificate program, many pre-med programs will grant some credit for the experience.
I 😍 LOVE 😍 working in EMS, and plan to continue the relationship once I am an EM doc. If you have any more questions, definitely drop me a line. I am happy to help.
