Uhh...I have to disagree. One point I haven't seen mentioned is the fact that if you're a paramedic for 5-10 years, you won't be 24 years old when you start interacting with patients in a meaningful way. Even if all of the patient assessment skills, critical thinking, and procedural skills that you learned as a paramedic were of no use to you as a physician (and I think most people realize they are), the fact that you're older and have more life experience does make you a better clinician. I'm sorry, but 20-somethings and 30-somethings tend to interact with patients in a very different way.
I can't even count the number of times I've seen comments on my evaluations about my maturity, or ability to interact with patients and other caregivers, or my ability to independently manage patients being way above my peers. I'm not that smart (trust me!), so I think some of it has to be the fact that 10 years ago I was running codes by myself, and deciding when someone was sick enough to jam a tube down their throat, and deciding when (with a base physician consult, of course) someone really shouldn't be resuscitated. I've had to tell people that their loved ones have died, run mass casualty incidents, and learned my strengths and weaknesses throughout the process.
Judgement and intuition are formed from your clinical experiences (hopefully). I'm sorry, but spending 5 or 10 years being the one ultimately responsible for a patient's care does contribute just a tiny bit to your clinical skills.
I've noticed that my classmates with little clinical experience just refuse to believe that someone who spend all day driving an ambulance for 10 years might know something they don't about taking care of patients. Those of us who were paramedics realize that we had the unique opportunity to assess and treat patients unsupervised--one we won't get again until after residency. Anyone who didn't improve their clinical skills (become a batter clinician) after 10 years of seeing patients has no place in the medical field.
So, become a paramedic to get into med school/residency? No way. Has it helped - hell yes!
I'm going to go take my arthritis meds now and curl up with a warm blanket on the couch now. Then i'll put my dentures back in, get some dinner and wait for medicaire to kick in.
