No, no - look, I think that people forget what primary care is
supposed to be about.
When you did your family med rotation, what did they stress, over and over again?
Health MAINTENANCE and disease PREVENTION. This is what distinguishes primary care from acute care - long term, continuity of care, that focuses on keeping your current level of health, and doing your best to prevent acute episodes of disease.
The ER
might fill that role occasionally. To be fair, endocrinologists, urologists, ophthalmologists, neurologists, and oncologists all technically fill that role occasionally as well. But just by incidentally filling that role does not make it a "primary care specialty."
Yeah, you
might get a breast cancer screening in the ED. So what? Will they follow up with you to see what that ultrasound/mammogram showed? Will they follow up with you after your mastectomy to see how you're doing? Will they continue to do routine pap smears, and focus on other aspects of your health? (Which begs the question - what's the point of doing a breast cancer screening in the ED if you never follow up on it?)
If you do the screening, but not the followup, it is, in my mind, VERY difficult to call that a primary care specialty.
P.S. I love how the thread is titled "Simple Question," and it's already turning out to be more than just a simple question.
