It's hard enough to have this conversation with someone outside our profession who doesn't understand our training...but I'll entertain nonetheless.
How much would a lawsuit cost?
For refilling a prescription? I'm not sure what lawsuit you're talking about, but let's say it's for liability should the patient (lets take an extreme case) die as a result of your negligence. Well, you assume that risk every time you prescribe any medication.
Now, since you're not actually a student and haven't taken law and medicine I won't go into scope or standard of care issues regarding malpractice. My point was that you'll eventually be prescribing these drugs, by yourself, for 3 years, every day, for the same patients and that will stop the day you graduate. Are you all of a sudden not competent to handle those issues once you're actually practicing? Perhaps for those who never refilled an insulin script for a diabetic in the first place, but that's not how we're trained today (incase you've never spent a day with a resident).
Copying another doctor's prescription is not the job of a physician.
Who's copying a prescription?
Well first off you said you would re-fill the prescription without doing the necessary examinations.
I never said that, but lets say I did...for someone who's been on sliding scale, like say a type 1 diabetic who's been on the same medication their whole life, what would you perform?
how do you know the current dosage is effective?
You've taken pharmacology, spent endless hours with these patients in clinic, spend no less than 3 years prescribing these medications to these patients, etc..you tell me? Oh, wait...
You will train for 7+ years in order to make sound medical decision for your patient...not to pad your ego.
So not only am I not a sound decision maker by refilling my patient's script, but I'm padding my ego by stating that my training is adequate to manage my patient? Pad on..
..it's about sending the patient to the best doctor for the job.
How would you feel if the endocrinologist said..."oh while your here let me treat all of your foot complaints...I do have an unlimited license."?
That's the patient's decision. The difference is, he wouldn't prescribe a medication he's never prescribed before for a condition he's never seen. Currently, we can't prescribe a medication we've prescribed every day of our training for a disease that nearly all of our patients have.
